Hi Martyn, thought I would drop in a comment here as you have the SR12.I own the SR11 and I believe that what you are experiencing is the results of AVCHD compression.I too noticed a significant difference in the two i.e what I saw live to the LCD and what was captured.If you were able to record the uncompressed HDMI feed to a good codec then the image you see in live mode to your LCD would be the same after editing. That is my area of interest and if you check out the captures I have done over the last few months below you will see that the degradation is indeed happening in the camera when it compresses to to AVCHD.When I capture to Cineform using a Blackmagic intensity,edit using Cineform and export to Cineform - there is no visual degradation at all and the picture is absolutley amazing.Of course what is uploaded to Vimeo is WMV so that loses some quality but the SR11 can produce a picture many times its value when recording HDMI output. HDMI/Composite HD captures on Vimeo I have also done some captures of the HFS10 using compsoite HD and the results are eye popping . As an aside - for those who are pinning their hopes on the Panasonic TM300 for semi pro work.Please allow me to humbly express my opinion - let me just say I bought one a few weeks ago (one of the first to arrive in the UK) and I sent it back after playing with it for the afternoon.Very underwhelmed - I have never been so disappointed with a camera that promised so much.Build quality was so so.Low light was poor even though it is advertised as great.It had horrible grain the darker it got and when you turned up gain in the dark it went all plastic like.A bit like when you add a slight pastel look in Photoshop.I have seen this look on some other Panasonic professional cameras as well.To my eyes the SR11 had a better picture from a sharpness and detail perspective - hands down - oh and I mean live to the LCD so no codecs involved.Subjective but in my opinion true.In contrast the HFS10 has blown me away.There is a small downscaling issue I believe i.e when filming straight diagonal lines one can see pixels peep out - don't know how to explain it but the lines aren't perfectly clean and straight -I think it is called aliasing but even so it is amazing.The SGblade seems to lessen this artifact.I do miss the touch screen but can live without it.The SR11 has an amazing LCD and the Canon's is not as sharp or high resolution - but it is usable.I assume the XR5200 will be very good to. In the end what did it for me was that the HSF10 had more resolving power,more manual control and 24p even if it is wrapped in a 60i stream (NTSC version from Japan) .Low light is a whisker better on the Sony no doubt but no progressive modes on the Sonys sealed the deal for me.I so wanted to stay with sony for digital cinema but I have now jumped ship to Canon and use that with the SGblade for my film stuff - the SR11 for PAL stuff. Let me know your thoughts on the videos.Best wishes. |

Henry I think Martin was referring to playback from the SR12 to his TV compared to his edited output. In this regard I agree with him that it is better than commercial product !!! In his case it is his editing rendering that is the issue not the AVCHD initial encoding. Any editing that does not use a smart encoder will re-encode the output and frankly I have found it better to then go to MPEG2 HD rather than poorer AVC encoders that are around at the moment not all of which are actually Bluray compliant.
I do agree however that the direct output to HDMI from the imager of the Sony's is likely very good and with a lossless encode at a higher data rate will be better than the current 16mbps limit of the Sony encoder. Ron Evans |
Hi Ron,
Understood and I think we are on the same wavelength.Perhaps my emphasis is that the damage is done at acquisition.Anyhow as it turns out I agree with him whole heatedly that after editing the AVCHD files there is a noticeable difference between what is played live to the LCD and what is captured.Could be from the render codec of choice - I agree.In a nutshell I was proposing however that the difference he is noticing is perhaps due to the pounding that in-camera compression does to a wonderful image; of course not withstanding anything else that is a weak link in the post production chain.I have placed a direct comparison between simultaneous captures to AVCHD and also Cineform HDMI on my vimeo channel.Difference is noticeable. I have converted my AVCHD files to the Cineform intermediate during editing.This has maintained any quality captured throughout my post workflow but found it always came up short compared to the initial live HDMI/Composite HD captures even if the final edit is rendered out to Cineform again.I am unashamedly a fan of Cineform as an acquisition format because the SR11/12 is amazing live out the HDMI/Composite HD port.I think that may be the difference that is being noticed but only Martyn can answer that. I can say the same thing for the HFS10.Went out with the family today in London - looked amazing on the Camcorder LCD - got home - watched it on the 40 inch Bravia and slumped my shoulders.It's useable but then again ........Aww shucks well I have been spoilt with this HDMI capture business....just wish that Nanoflash were'nt so pricey. |
One interesting thing that I've found (and I don't know why it's taken me so long to see this) is that there is much more 'headroom' built into the Sonys. By that I mean Canon is apparently using more in-camera sharpening than Sony.
It's easy to see the effect of this when I tinker with my Pioneer Kuro's sharpness control. With the Canon (HG21), raising sharpness just 2-3 clicks will bring about some ringing and edge enhancement. But with the XR, I can raise sharpness 8 clicks and still see no evidence of ringing or edge enhancement. What this does is to allow you to raise the sharpness of your HDTV when playing the XR footage. This has a pretty dramatic impact on the apparent sharpness of the video and makes the Canon and Sony much closer in appearance with regard to sharpness. |
First week with 520V
I am a bit late to this party but only found it in the last couple of days and then had to wait the weekend to get validated.
I went between the HFS10 and 520V for a good while and settled on the 520V. The creative-geek in me much favored the Canon, but with my wife being as much of a user of this particular camera as I, I went for the 520V. I'm waiting for Sony to update something like the A1 which I sold to get this one that is along the lines of the JVC HM100, but the 520V makes a lot of sense for the time being. I put up a couple of first runs at the links below.

HDR-520V Stabilizatin Stress Test
I just posted a short example of my running backwards while filming. It has a clip with and without iMovie's own stabilizer processing.
Sony HDR-XR520V Stabilization Stress Test on Vimeo -Michael |
Just courious but what happens if you use both stabilizers?

Interesting - a lot of the frame is cut off using the iMovie stabilizer... but does seem to help a bit.
I'd think that a small bracket rig/homebuilt fig rig type device would smooth that out even more as well, but the new super OIS does an amazing job. I've run a few test runs with some of my stabilizing rigs, and am very happy with the results. |
Quote:
Yeah, it's a smooth, zoom and crop process. On that clip it was about 130% (iMovie's scale) where 100% is just the normal video. You can control the trade off between smoothing and cropping/zooming. 130% is pretty heavy, imho, and you can see the cropping that happens at that level playing the clips back to back. On some other shots I've done, 10% or so is just enough to make the handheld HD video very usable without being totally distracting with shake or cropping too much. I would still prefer a proper stabilizer/glide-cam kind of rig, but I can't exactly fit that in my wife's purse when we're out to the park for fun. -Michael |
Regardless of the image quality and bells and whistles, I would go with the S10. Of the two, it's the only camcorder that offers full manual control over gain, WB, shutter, iris, focus and zoom.
|
I think the issue of gain is much less valid when comparing these two. When you see the Sony's picture in low light, you surely don't get concerned with gain. Because the Canon isn't nearly as good in low light, you do need control over the gain.
But I found that even limiting gain on the Canon, gave me a picture that was very dim and lacking in detail. As for control of WB, the Sony gives you that too, including MWB. Focus? They both have manual control over focus, though without a ring adjustment neither is particularly good. So the main differentiator is that of iris and shutter. If you need that and don't do 'run & gun' type video, than the Canon is a good choice. I found, even with my two Canons, I almost never use manual iris or shutter since it's almost always spur of the moment shots for a cam like this where I don't have the time. |

Once one learns how to manipulate the Sony, it's surprisingly controllable. Yes, independent control of each setting (WB, iris, gain, shutter speed) on individual buttons would be great, but not terribly practical in he small form factor. Upsize the cam to something around the size of the old TRV900, now you've lost portability, but I think it would be a decent trade.
With AE shift and exposure controls easily accessible from the button/knob, you've got fairly effective control. Frankly the spot focus function is probably a better option than "manual" focus on a small cam with a small monitor. Anything other than a full size ring is mighty fiddly of you're honest about it... and if you're realy trying to "focus" on the 2.7" LCD... well, good luck with it... The strong points of a good clean low light image and excellent OIS (and a viewfinder, bigger LCD) are pretty good and compelling package for many users. I'd prefer those things even at the expense of a slightly less sharp "good light" picture. |
HDR-XR520 as second/backup cam to Z5
Well, I used the XR520 on a real project for the first time on Wednesday, in conjunction with the Z5 and I must say I'm immensely impressed with the low-light results from such a small cam.
The gig was a rock concert for kids to show off their talents to family and friends, so it was a (very) low budget affair. It was a single-handed effort with the main cam (hand-held, mobile) being my Z5 and 2 small cams mounted on clamps fixed to structures on either side of the stage. The 3rd cam was a borrowed (from a friend) Panasonic HDC-HS100 which I had seen results from in good lighting which were pretty good. However, the low-light capability was much less impressive - to the extent that I don't think I'll even be able to cut it into the finished edit due to the massive difference to it's footage compared to the 2 Sony cams. I'll let you know how I get on once I start editing. At the moment, I'm just converting everything to Cineform intermediates. You can see the difference between the Z5 footage and the XR520 footage (as you would expect for cameras with several thousand pounds difference between them) but it's not so different that it disturbs the viewer when cutting from one to the other with all the coloured disco lighting - unlike the footage from the Panasonic. The audio was recorded on an Edirol R-44 using 4 mics on seperate channels (guitar, bass, drums, vocals). I did a quick test using PluralEyes for syncing the 3 video tracks (using the on-camera audio for syncing) with the 4-channel Edirol tracks and was suitably impressed - it certainly speeds up the syncing process from doing it visually! I'll probably buy the release version (just released). Well, back to work. I'll let you know how things progress. The star of the show is my 12 year old nephew, who is a killer guitarist! Watch this space! |
My main setup is Sony FX1 , SR11 and XR500. Lots of projects are by myself with cameras on tripods or Magic clamps. SR11 and XR500 focused with spot focus and AE shift at -4. In good light they are better than the FX1 a lot of the time. FX1 has the edge when things get difficult to expose or focus for but considering I could buy two more XR500's before I get to the cost of the FX1 the XR500 is really good. I am looking forward to see how the NXCam family turns out as I am sure for me one of them will replace the FX1. The XR500 is used as the full stage camera mostly as it responds great to the lights going up and down with low grain again less than the FX1 a lot of the time. I too am very impressed with the XR500 for the cost.

Lack of progressive recording has to be a big downer on all sony consumer cams.
|
I'm still struggling with understanding why people think the progressive recording is visibly superior for normal HD usage playing back through an HDTV. The 1080i recordings from the Sony cams look spectacular on a Sony 46" 60Hz TV, and I understand the newer TVs at 120Hz do all sorts of clever interpolation and the video might look even better there. I can't even really tell the difference between playback quality on a PC (nominally progressive) vs the HDTV (nominally interlaced) except that the former is on a much smaller screen and isn't my target output device in practice. So that rules out the only source of regret I might have about using a 1080i cam.
I've also heard that some of the advertised 1080p cams aren't actually capturing in that mode, they just interpolate themselves and play it back that way. I understand the technological difference but wonder how much it really matters at this point. For example, I definitely don't buy that a 720p recording looks superior to a 1080i one on my TV. So is the difference something that is visible to the average consumer on an average HDTV today, or is it a futures consideration except for people who are trying to emulate film cameras used for movies? |
I'm with you Tom. Since most modern HDTVs have excellent conversion to progressive, in many cases there is no difference at all between feeding the HDTV an interlaced vs. a progressive signal.

On the other hand, Canon's so-called "1080p" modes are really 1080p streams embedded inside a 1080i container. Thus, they are read as 1080i video in a program which cannot properly remove the pulldown encoded in the videos. |
When we bought our HDTV (a Sony XBR) at least two years ago, it was clear from the manual that the TV itself is now a very powerful graphics processing computer and would do all sorts of things with the incoming signal as opposed to just throwing it onscreen. The 120Hz models sound even more so.
So are there any consumer cams doing true 1080p not wrapped in a 1080i container? I had read a bit about that recently and that's part of why I don't feel any need to go to 1080p - I've gotten the impression that there's some advertising hype going on there. If there are some top to bottom 1080p cams out there (less than $1500), will there be a noticeable visual difference between that and the Sony 1080is on a good LCD 120Hz HDTV? Or does the TV's own processing cover any gap? Again, I don't really care that much about PC playback, if I want to watch the video for entertainment, I'm going to use the TV for that. |
Here in the uk the HV30 does true 25P recording and the look of the filming is better than my previous SR12 as is the overall colour rendition.

Shooting 24p has a purpose if one is going to transfer to film and show at a festival from a film projector. Easier and lower cost way of creating the film. In my mind when festival all go digital projectors there will be little point. Might as well remove the hassle of motion and keep all the other techniques of composition, lighting colour saturation etc. We don't need to stay with the legacy from a century old business decision of the movie industry( it had nothing to do with art or technology it was MONEY). Finally you must have gathered I like smooth motion and as such have no problems with my 60i Sony's. Also my XR500 gives a much nicer clean picture than my FX1. So I will be buying the new Sony NXCAM when it comes out in the new year. Since it will also do 1280x720P60 I will be happy. Ron Evans |
25P in pal looks far better if used properly, running around hand held would of course not, am i right the 7D only records progressive.
Pretty good i reckon wish it was mine, not the music though. |
