do you have a UHD monitor or a 1080p only? I ask because I wonder whether the reason for not being able to see the difference (even in fast moving footage) may be the monitor....I mean....albeit I have only a 1080p monitor, I can see the difference when I shot 1080p or 4K, but I cannot see well enough the 4K video and hence I also can not spot difference between the "almost" same footage at 60Mbit vs 100Mbit.

I believe that in theory the difference would be similar to the one we get with a 1080p at 15Mbit vs the same at 25Mbit....not a huge difference in bitrate, but still almost the double....I would bet I should see some difference....(I am puzzle)
No, I don't have a UHD/4K monitor or TV. For now, I just want to see a difference on my computer screen and 1080P TV. I've watched YouTube videos of other camera tests for this type of thing and had no trouble seeing the difference.

Got it. I will also check for similar comparison on either Vimeo or Youtube (I also do not have a UHD monitor...even if the recent ones are not so expensive and I am considering.... :-) )

I'm no expert, but I believe the amount of difference depends greatly on the nature of your subject and lighting conditions.

Extremely detailed objects such as leaves, grass, should show a difference, as someone else has pointed out in a simlilar thread.

Well lit footage of a calm ocean or solid objects, I suspect, will look about the same both ways.

I believe footage shot in poorly lit conditions can benefit from the extra information, and should accept touch ups and FX much better as well, at least that's my understanding.

Hey Mark
Get a 4k monitor
It will blow your mind

Another test, with some trees, water, moving objects, a panning (fast) shot and a slider shot.
No cropping or adjustments made, just editing cuts. Was uploaded to Vimeo as UHD, so if one wants to download in original resolution, they can. It's a big file though.

Thanks for the upload Mark - for me the section that may show the most difference between the 2 bitrates is the shot of trees between 1:10 & 1:20.

However the downloaded file from Vimeo unfortunately only has a bitrate of 22mbps so doesn't quite work unfortunately.

Would it be possible to do a full res screen grab of your video at say 1:25:00 - that should help show up some artefacts?

Many thanks!

I can see no observable difference between the two, seems to be no good reason to shoot in 100mbps especially with the significant increase in memory required.

Paul,

I wasn't able to upload the screen-shot of the tree until I re-sized it to 50%. Not sure why it wouldn't go at original size since it was well within the size limits listed for .jpg files.

I have also uploaded a screen shot of the toy train that is cropped in quite a bit.

I took 4 screen shots of the tree clip and it does consistently show that the left side holds up better when I magnify in. The 60Mbps looks more "muddier" and pixelated.

Andy, I agree. It's really a minor improvement and what that means to me is I won't be buying any of them 256GB cards just yet (too late about the 128GB cards, jumped the gun and bought one already).

On the bright side, at least they didn't charge us for that upgrade.

I think it may make a difference if one is cropping/panning the image to 1920x1080 and then further processing in edit. Especially if like me you would like to use Respeeder to create a 60P file. The interpolated frames should be better with the finer detail.

Re: AX100 Firmware 3.0 is out today!!
 
Not familiar with Respeeder but I have Twixtor for creating slow motion. Would be great if there's a noticeable improvement there. Even on static scenes, if I crop in to a ridiculous size, like SD, I can tell that the 100Mbps is less pixelated than the 60Mbps. But I think for 95% of what I typically do with the camera, nobody will know the difference. Great little camera that fits in my dSLR bag along with the 6D. (Man, I haven't picked up my XF305 in awhile now.)

I agree that the difference is less obvious than I expected, and much less obvious when viewing video rather than screen captures.

I have the X70, and since its upcoming 4K upgrade has been announced as 60 Mbps rather than 100, these clips raise the likelihood (pending seeing actual footage) of my purchasing that upgrade from 40% to 50%. In other words, it's not a deal breaker for me given the things I shoot.

Re: AX100 Firmware 3.0 is out today!!
 
Had the X70 4K upgrade been for 4:2:2, I would then say the differences would be more visible. But then, at only 60 Mbps, the compression ratio would be quite high.

Bruce Dempsey April 6th, 2015 09:09 AM
Re: AX100 Firmware 3.0 is out today!!
 
Seriously You need a 4k monitor
There's a reason the 100mbs is only available in uhd
You wouldn't shoot hd to view on a uhd monitor and viceversa

Thanks for that Mark - yes it does show a marked improvement, interesting!
