So a card comes from the factory with different formats depending on capacity. That would explain why my 16gb and 32gb cards didn't work until I formatted them ex=fat.

But why doesn't the ax100 format as ex-fat since it should know it must be ex-fat for xavc? It looks like the camera simply reformats it to be what it was. But, why? Or, why not a menu item to select?


That's a problem if traveling because one wouldn't have a computer along. So would one need to buy a 64gb? Lots of luck if one is tibet or even at BB which doesn't stock "expensive" cards.


My 16GB was new and uhs-1. U with a 1 inside.

By the way, using the AJA speed test -- the card was nowhere near claimed speed. Only 35MB/second Read and Write.

Re: Sony FDR-AX100
 
Maybe format depends on what the current record mode is set at in the camera. AVCHD does not need ex-FAT.

Re: Sony FDR-AX100
 
It's funny. I shot some footage with the AX100 at my local Best Buy today. (they let me shoot to my own card)

I shot at 30p using a 1/30 shutter and 1/60 shutter. (did not test 24p)

When looking at the video I shot, I noticed that it all looked extremely sharp. Slow panning and low motion scenes moved pretty smooth. However, every now and then I would get enough people walking by the shot to cause movement to look very "harsh" or unnatural. And again, other times it looked OK

Is anybody else noticing occasional "harsh" movement? I also noticed that the codec would sometimes "smear" pixels that were moving even very slowly. Not all the time, just occasionally.

Anybody else see this? Is this because of the 60MBp/s low bitrate?

Another thing I noticed when testing the video at home was that I saw plenty of compression artifacts on a 1080 zoom/crop. Its not sensor noise, its definetely codec noise the the blacks. So lets see how much zoom cropping that we can really do for 1080 delivery at this bitrate.

I preordered mine lat week. Cant wait to get it!

I REALLY cant wait to see what Sony might do with a "pro" version of this camera next month!

Hearkening back to the HC1 which ran me 1999.00 at pre0rder time from the states and then a few months later I was able to get one from Japan for 1000.00 and then a few months after that the HC3 was released for even less.
Unlike most, I'm happy enough to use a consumer version as I do videographer stuff rather than cinema and besides lately nobody seems to notice or care what the gear looks like especially if an on tripod monitor is used then it looks Pro enough and is OK.
Seems the deFacto and must include feature for cam vendors in the upcoming crop of cheap cameras will be 4K. so I might wait a bit and get 3 cheapo 4K sonys for multi cam and noOne except the pixel peeping pros will notice any difference.
I'm a contrarian in liking the benefits of relatively smallish sensors as a lot of my shoots involve fast movement of the subjects and the camera as in figureskating and various sports therefore the maintaining or really fast re-aqusition of focus is very very important for my work. Sony's release the other day of the 1/3 4k sensor for use in digi and camcorders is sure to be brilliant and no doubt will shoot 60p and beyond ....my 2p

Cliff, if your display has frame doubling capabilities, you'll be amazed at how much better motion looks.

When I implement frame doubling on my plasma, motion goes from just as you described to buttery smooth almost like it was true 60p.

I knew when I got the AX100 (the GH4 will be no different), that motion smoothness would take a hit. It's the reason I've never been a fan of 30p. But most modern displays have frame doublers or more, so motion is smoothed out tremendously. I've seen this on both my plasma and Sharp Elite LED.

Of course these same frame rate increases result in the dreaded soap opera effect with film, so you certainly don't want these engaged while watching movies. But for the AX100 output, it's great.

BTW, I stopped in to an Apple store yesterday and threw my clips on a 27" IMac. The clarity and detail were beyond belief. In fact it drew a crowd of about 5 or 6 people who were stunned by how good the footage looked. I believe at least 2 in that group were going to order the AX100 based on what they saw. The scary thing is that this still wasn't as good as when I saw it on an 85" Samsung UHD TV with full array local dimming.

But that 27" IMac's display is just superb. Too bad my editing programs don't run on Mac.

Re: Sony FDR-AX100
 
Sony does specify an SDXC card for XAVC.

=================

"SDHC cards are shipped preformatted with the FAT32 file system."

"SDXC adopts Microsoft's exFAT file system as a mandatory feature"

So one must buy SDXC cards and they start at 64GB:

SanDisk Extreme Pro 64 GB SDXC Class 10 UHS-1 Flash Memory Card 95MB/s SDSDXPA-064G-AFFP

SanDisk Extreme Plus 64 GB SDXC Class 10 UHS-1 Flash Memory Card 80MB/s SDSDXS-064G-AFFP

Lexar Professional 400x 128GB SDXC UHS-I Flash Memory Card LSD128CTBNA400

These cards can be very expensive unless bought on-line and may not be available in many locations.

On another site they claim much slower cards work fine -- such as the SanDisk SDSDU-064G-A11 64GB Ultra SDXC Card 30MB/s (Class 10). It's claimed to be UHS-I but it only has a 1 and not a 1 within a U so who knows.

Review: "The write speed is 11.28MB/s which is almost double the requirement for recording full HD video. It is above Class 10 but just barely."

It's half the price, but writing dual streams may be a whole different ball-game.

Can anybody with an AX100 see if their HDMI port is outputting video in 4K while recording?

Steve, this morning I took a 32gig SDHC card I had been using in my RX10 and reformatted to exFAT. I put it in the AX100 and it recorded in the 4K mode perfectly. No error messages.

BTW, I had no trouble getting an SDXC card. Amazon and B&H both had it.

Cliff, I'll take a look tomorrow, but I doubt it will output anything via HDMI while recording in 4K.

You do not need those expensive cards. Waste of money. This has already been discussed. You can use, for example, Sandisk Ultra SDXC cards (30MBs/sec) which are cheap and available everywhere ($45). There are even cheaper cards that are class 10 and 64GB. They also come formatted exFAT.

The bitrate for 4K is 60Mbps. That is less than 10 MBps, so you do not need a really fast, expensive card. It is a major advantage of the AX100 compared with any of the non cellphone 4K alternatives - you can use cheap, readily-available sdxc cards.

And, you can format any card to exFAT with your computer before you travel. I use Ultra cards, and have shot hundreds of clips in 4K using them, including this video: https://vimeo.com/89673510#comment_11319741.

Once the card is exFAT, you can format it in the camera to get rid of files, over and over again. No computer needed.

Mark has shown an easy workaround by using a tablet or phone via wifi in conjunction with the PlayMemories app on these devices. You get both the live video from the camera and telephoto control on the tablet or phone while the camera records in 4K.

It may not be what you want, but you can view what the camera sees while shooting 4K remotely over wifi in real time.

Here is what it looks like:

You can see the red rec symbol is on (the camera is set to 4K) so the camera is shooting You can also see the zoom control and the start/stop button.

Here is the 4k clip taken remotely, with zoom:





This is my typical low-light set-up shot. Any jerkiness is the stream, or Youtube compression.

Re: Sony FDR-AX100
 
I recall that when I made the jump from SD to HD about a decade ago, that with my old Sony HDV camcorders like the HVR-A1U that if I shot in 1080i HD, the camcorder could be set to down convert to SD to play on my old SDTVs or to edit in SD on my PC. It was a handy feature to have between the transitioning from SD to HD.

Now, that we might be transitioning from HD to 4K, I was wondering if a similar process is possible here with the FDR-AX1 like being able to shoot 4K and then down convert and playback in HD on your HDTV or to edit in HD on your PC. Is that possible? I ask since 4K shooting might be the future, it is not the present right now.

Mark Rosenzweig March 24th, 2014 09:43 PM

Re: Sony FDR-AX100
 
The AX100 will play (downconvert) the 4K videos in (to) HD if it is attached to an HDTV by HDMI automatically. And, of course, you can convert 4K to HD in any editor, saving the original 4K files for later.

In the meantime you can also upload the 4K videos to Vimeo or Youtube, letting them make the conversions to HD (you do not have to). This works fine. And on Youtube you can also stream in 4K and view in 4K if you have a 4K viewing device.

Re: Sony FDR-AX100
 
So HDMI (1080) field monitors cant be used while recording in 4k. (there goes my Atomos scopes and RGB parade.)

I guess that Sony is also making it very loud and clear that they DO NOT want you bypassing the 60 Mbp/s compression in any way, shape or form at this price point.

Now, the big question will be: If Sony releases the "pro" sister camera to the AX100 what "extra" will they give you for the $1000+ bucks?

XLR Top handle for sure.
XQD card socket?
100 Mbp/s codec at 4:2:0 8 bit?
"unlocked" HDMI out while shooting 4k?
Histogram?
"NXCAM" badge?

I'd return my pre ordered AX100 and spend the extra $1000 for that.

Sony has a Sunday, April 6 live web streaming press event in Las Vegas. All questions will be answered then!

Re: Sony FDR-AX100
 
So far the videos are looking pretty impressive...

Sony runs a risk if they release a "pro" version from what I've seen so far. "Watching video" is more like looking through a window, even on my old 1080 screens, I'm not seeing any major flaws with the 30p (though I'm expecting fast motion might have some gotchas). I'm seeing much the same quality that the RX10 is delivering for me already, and with any luck the RX10 and RX100M2 will be good for "B" cams alongside the AX100. A lot of imaging power in small packages!


Sony would have to either price very high, or do something else to keep quite a few of their other cameras competitive... that's not to say I don't expect an NX version of this any day now, but Sony will have to be very careful not to cannibalize sales from themselves as they blaze the 4K trail with this thing. The so called "limitations" don't seem all that off putting as it is...

They don't cost too much. I have two Sony 64gb SDXC 94MB/s cards that I bought for $60 each online at Amazon. Like others said you don't need to use cards that fast, but for me it's really nice to be able to quickly transfer the footage off the camera when I'm done with a shoot so I went for the fast memory cards as they are relatively cheap anyways.

It wouldn't make me return my incoming AX100 as I have specific needs for that camera (it will replace my NX30), but I do hope they have a larger sensor 4k pro model that could replace my VG900. Either way, good times for good camera gear!

Yes, IF you have a computer one can reformat with it.

And yes, you can get an SDXC card on-line. But, at B&M BB 64GB is $279 and will not likely be available because "their computer has determined that not enough will be sold to justify stocking." Try in small town USA or in Burma.

What one CAN do if needed is good to know, but Sony specifically states SDXC.

And, with only a few days of experience no one can say anything more than "no error messages YET."

Writing 2 streams, one at 60MBps (is this a minimum, average, or maximum -- it's not yet been measured?) and one at 3MBps, I have decades long experience telling me to not underestimate burst rate peak's ability to cause a glitch.

Buying a $2K camera and then taking a chance to save a few bucks strikes me as a real newbie move. Paying about $50 more seems worth it to me. Later when the cheap cards have proven themselves, I'll think about saving money.

Moreover, when reviewing a camera I can't take a chance on MY making an error.

Steve, 64 gig SDXC cards can be had for less than 1/2 the price you quoted from a B&M. Buying from a B&M at that price strikes me as a newbie move.

Frankly I think the paranoia about losing all your pre-formatted cards or the cards suddenly failing, is just that, paranoia. If you're really that concerned, buy only SDXC cards at under $100 and put two in each pocket and two in your socks. No biggie. ;)

Now what happens if you lose your camera on this trip too? :)

Dave, I know I've said it many times, but there are virtually no motion issues when you watch the AX100's 30p, 4K output on an HDTV or 4K display with frame rate doubling. Almost all good displays (plasma & LED/LCD) have had this capability for the last few years.

Anyone watching in this manner will be very hard pressed to see the difference between this and true 60p. For AX100 owners I can't stress this enough. The difference between using this feature and not with fast motion, is huge. To me, it so minimizes the issue of 30p, while watching on a display that has this feature, that it becomes almost moot.

As for intercutting RX10 and down rez'd AX100 footage, your biggest problem will be the very obviously sharper AX100 footage...even in its down rez'd to HD state. It's impossible not to notice it.

Kind of nice to have these 'problems'. :)

Yeah, but much larger, much heavier (over 2x the weight), a 1/2.3" sensor vs the AX100's 1" sensor and a price tag that's over double.

So as with many things in life, each approach has its pluses and minuses.

Cliff, as far as I know, you can always choose to output the AX100's 4K to an external recorder. That should bypass the 60 Mbps internal compression depending upon what you record it to. The output limitation is only when you're recording 4K internally.

I know for sure I saw my AX100's live, 4K output, on an 85" Samsung UHD TV. It looked superb.

I have the FDR-AX1 a better choice at the moment since the PXW-Z100 is currently only XAVC 10bit 422 and needs the fast and very expensive XQD S cards. 64G card will only last about 10 mins at 60P too. This summer the PXW-Z100 will get a firmware update to record LongGOP which should ease the cost a littlebut now its a very expensive option. Both these camcorders are not great in low light mine is at least 2 stops slower than my NX5U.

Yes they both do have lots of options but miss things that are on the NX5U like smooth gain switching and a nice ramp on the power zoom. At the moment they also do not have data code or time code. Lots of buttons not yet working !!!

I think Sony are rushing to gets lots of 4K products to market.

Bought my AX-100 at Samy's Camera in Culver City, Ca. this past Saturday. Walked into the store and first salesperson said they didn't have it yet. I Spoke to another sales person and asked when they would be receiving it and he said he had one in the back! I Walked out with it and had fun playing with it enroute to Philly while flying on Sunday. Had issues with card at first, and couldn't record 4K, then discovered the exFAT format trick, (based on info in this forum) and walla ! 4k looks gorgeous ! Extra battery and cards arriving via UPS today.

Dull cloudy day here in the Atlantic City area and can't wait for the sun !

BTW Samy's salesperson said he had received six cameras. Three were purchased by a major movie studio on first day and one to an individual before me… He Claims mine was the fifth in LA County.

I agree. I'm going to use the 16gb in my MB Air for Mavericks and Resolve. The 32gb goes to wife's MB Air to giver her more storage.

I've ordered a 64gb sdxc from Amazon for $100.

I can't believe BB wants almost 3x more money.

And yes, I worry about the ax100 going missing on a future 3 week europe trip! I'm a pro at worry. :)

Seriously,on our recent Asia trip it was nice with my wife shooting on her iphone. No computer and no camera to worry about. We could upload every night. A long way from mailing 8mm rolls home from Europe in the `60s.

By the way have you seen the AX1 shootout against an iphone? I pity the Japanese camera companies because most everything they can do can be emulated with software. And, Apple is hiring camera guys and Samsung has plenty in-house.

PS: the interesting thing is i read the AX100 manual multiple times and never noticed that under XAVC it said -- with no warning -- SDXC.

I was comparing my V1 manual to what I'm doing for the AX100 and noticed that Sony had simply dropped many menu items. Perhaps removing functions is a trend. /on the other hand, the touchscreen operation is very simple and fast. It is a real pleasure to use.

At NAB there will be a neat device for the AX100 that may be a must have for many. I'm under NDA but will be doing a review of it.

Somehow I'm not surprised. Where a high quality image is needed and the risk of total destruction is great, I can see movie studios buying bunches of these. With their budgets, these are throwaway cameras that also happen to shoot wonderful video.

To me, it so minimizes the issue of 30p while watching on a display that has this feature, as to render the issue almost moot.)

In the ntsc world our flat-panel tv's always have been able to present 60p. 60i fields are paired to 60p. 24p has 3:2 pulldown added to make 60p. (And some hdtv's allow 60p input.) So we have no choice -- if 30p comes in, we see 60p because each frame is repeated twice.

An optional feature ups the rate from 60p to 120 or 240 -- now almost always with the creation of intermediate frames. So are you talking about turning ON the 120/240 mode?

Moreover, doesn't the AX100 auto-sense the hdtv and automatically output 60p or 60PsF (which looks to the tv like 60i). I can't see Sony ever outputting 30p.

The question of 24p is more complicated. Some hdtvs do accept 24p -- and they could signal the AX100 to output 24p. In this case it will be the hdtv that adds pulldown. But, if the hdtv can accept 60p then the camera can add the pulldown. If neither are accepted -- then pulldown is added to make 60PsF which looks to the tv like 60i. Again, an optional feature ups the rate from 60p to 120 or 240 -- now almost always with the creation of intermediate frames.

I would never use this with 24fps as it removes film judder. In fact, I probably wouldn't use it with 30p for the same reason.

With all the RAW Cinema cameras being used at 24p, I figure why not go with the film look. Plus, 24p goes perfectly to BD, it will obviously be supported on BR2, and it makes more efficient use of the bandwidth allowed by 4K youtube. Moreover, 24p easily becomes 25p. It really is a world standard.

Plus, following the camera/subject motion rules for 24p provides the added benefit of reducing/eliminating RS.

I LOVE 60p, but it just isn't going to be adopted with 4K being a much bigger buzz word. (Youtube will not transmit 1080p60.) And, acceptable 60p can be generated -- as you say -- by the hdtv. Maybe with 8K.

An optional feature ups the rate from 60p to 120 or 240 -- now almost always with the creation of intermediate frames. So are you talking about turning ON the 120/240 mode?

Yes Steve, you are correct, I'm actually speaking of the rate doubler that ups it to 120 or, in some cases, to 240. It's this increase that smooths out the video and makes it look as if it were recorded in 60p. But as I said, this is the same increase that causes the SOE (soap opera effect) when watching film. But I see no ill-effects with the 30p video from the AX100. I also saw this same benefit with ordinary cellphone video that is also generally 30p.

I don't think the output of the AX100 is looked at as 60i by the display. When I feed the camera output to my Samsung F8500, it sees it as 60p. If the display saw the output from the camera as 60i, it would report that, as it does from my Directv STB. When I switch to my STB, you can see the TV reporting back the signal as '60i'. With the Sony, it reports 60p.

I can honestly see no downside and only benefit in enabling the doubler and minimizing/eliminating the stutter of fast motion. I don't see this as the same thing as removing judder in film. If you're watching film you generally want the look of film. To introduce the soap opera effect by using a doubler merely adds the look of video and you no longer have the look of film. But with the AX100 or most other video cameras, I'm trying to retain the look of smooth video, not film. 30p will never look like film IMO.

Looking at the "Hello Kitty" video, it looks pretty good, a bit of motion blur, but not objectionable, actually looked "good" considering, smooth enough and no "stutter" or jerkiness. Perhaps the higher resolution "covers" for the lower frame rate?

RS might be a rare issue, but not a problem for most things, and it's not like other cameras won't have the same issue. Careful panning and not shooting moving trains at close distances will probably do the trick!


So Ken is the AX100 THAT much sharper than the RX10? I know the RX10 &100M2 are quite sharp "HD" and the AX100 is obviously sharp displaying as 1080 (I don't have any 4K screens!). I suppose the RX10M2 will bring 4K to that model... It's scary to see such a big jump in video quality in such a short time! I guess with cell phone sensors and software chomping at the camera market (actually swallowing many parts whole!), the manufacturers have to really up their game to have anything saleable and appealing to the "consumer"!

I suppose it's time to spec a 4K capable computer system! Anyone have one of those "cheap" Seiki 39" 4K TV's as a "monitor"?

Now to go stand outside a studio and try to catch a "throwaway" <wink>!

Glen, congrats, you really did such a nice job with that video. Very impressive.

Yeah Dave, it really is. I remember being so impressed with the detail from the RX10 and now, in comparison, it looks more 'ho hum'. Now remember, I'm talking about viewing both on a 1080p display and I'm talking about starting with a 4K file from the AX100 and down sampling to 1080p. Using that criteria, the AX100's down sampled 1080p is significantly sharper. If you initiate a recording in 1080p on the AX100, it's not nearly as impressive as it is when it originates in 4K.

Of course you have the added benefit of now having an archived file in 4K even if your immediate intention is to only use it in HD.

This actually didn't come as a major surprise to me having viewed a number of AX100 videos prior to my purchase and down sampled to 1080p. I could tell that look was not the look I got from my RX10.

Last year I reviewed JVC's 4k that shot at 60p. Then I realized it couldn't go to BR or to Youtube. (Unless i scaled it to 720p.). To get 60p on Vimeo I would have to pay them -- which I wasn't willing to do.

I was at a dead end. At that point I became involved with the Digital Bolex which seemed cheap compared to the Sony AX1. I've now gotten so used to 24fps it doesn't bother me anymore.

<< Technically, all these RAW cameras have zero edge-enhancement so edges are soft and it is the hard edges our eyes lock onto to create judder. In theory, 4k video should need edge enhancement because there is so much detail. Thus, judder should be low. >>

Of course, now we have the d16 at $3300, the BMPC4K at $3000, the AX100 at $2000, and the BMPCC at $1000. And, the under $1000 Chinon. And, I haven't been to NAB yet. There are so many great choices!

There may be a trick IF I WANT THE FILM LOOK OF A BMPC4K. Use FilmConvert to add a bit of grain which MAY soften the AX100 edges a bit -- as well as shifting color to one of the Kodak Vision 3 stocks.

This may prove to be an interesting experiment because Cinema is in and Video is out. Look at the content of the only video magazine left. :)

YAWN. Seriously Steve? In this day and age we are STILL pronouncing things "dead" or "out"?

I'll need to convey that tidbit to my clients as I prepare for my best ever (based on current receivables and projected work) year of video production.

Since 4K is for my own personal pleasure, I have no concern about what's 'in' or 'out'. Never bothered me before and it surely won't now.

My personal goal is to always get as close to the look of 'reality' as possible, to recreate as precisely as I can, what I saw. Cinema doesn't do that. In fact it moves you in a totally different direction. If I were an Indie film maker, it would be a different story, but I'm not. "Dreamy look"? Not for me. "Stylized look"? Not for me.

Frankly, the overwhelming majority of what I see from guys that shoot RAW, look like utter garbage. Properly grading and getting the colors 'right' with RAW is a very difficult process. That's why the Hollywood guys get paid the big bucks. A random look almost anywhere on the web with the average guy showing off his RAW edits, show how painfully distant those skills are from the average bear. But of course the average guy that shoots RAW IS looking for a 'stylized look'. In fact, when some guys show a RAW video that's been graded and produced to look more like 'reality', his results generally get met with poor reviews from other RAW shooters. Such is life. Those rare RAW shooters are producing the kind of video I like.

For me, and the look of reality, the AX100 gets me closer to my goal than any camera I've used before and it does it with a minimum of fuss.

Whatever floats one's boat. :)

...he said with his tongue firmly stuck in his cheek.

Very funny Steve, but you should have placed a bunch of smilies after that comment lest people take you seriously. But just to go with that notion for a bit let me ask which cinema look is in? The horrible juddery 24p mess of unwatchable rubbish produced by many if not most indie film maker wannabe's or the look of, for instance, master cinematographer Christopher Doyle as demonstrated in the classic 'In the Mood for Love'. And there are thousands more somewhere in between.

Here's a suggestion: do a simple survey as follows. Next time you are at a function, partly-like with people happy, chatty, freely opinionated and loose, just normal people and absolutely no film or film related people present (which of course means billions of sane people on the planet totally disinterested in our favorite subject) and ask them out of the blue if they prefer 24p, 30p or 60p. If that mostly draws blank stares don't be surprised nor dismayed and then ask if they can name any production they recently viewed that was convincingly cinematic, filmic (if you can bring yourself to say that non-word) and conversely if they can name any production they recently watched that decidedly was not.

Other than that infinitesimal cohort that is directly involved one way or another (including us or course) people just don't give a toss.

'Video is out'! Very funny:-)
