Re: AX100 Firmware 3.0 is out today!!
We have had the 100Mbps update for a few weeks now and I thought I would ask if anyone has really seen any difference other than a doubling of the storage required. I have not seen any perceptible difference in any of the posted on-line comparisons. Last weekend I took some footage at a wedding and used 60Mbps, it stood up well to some increase in saturation in post and overall I am very pleased with the results. Auto focus only hesitated a couple of times (indoors) and hung on to the foreground faces. The challenge in editing was to make the best quality DVD with minimal shimmer in leaves/gravel outside. I found 'video to video converter' with 2 pass encoding to down res the 4K to give the best results.

Re: AX100 Firmware 3.0 is out today!!
The search continues...
I am working on a follow-up video, but the clips I've shot so far don't show any difference. I shot trains, palm trees, water fountains at a park, did a fast pan of a flower bed... not seeing any difference. My 1:20 video is 1GB in size already. I'll have it uploaded tomorrow sometime after I add one more scene with motion. I'm not sure what good all those extra bits are doing. Mark |

Re: AX100 Firmware 3.0 is out today!!
Hi Mark,
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) |

Re: AX100 Firmware 3.0 is out today!!
Even if indeed there is not much difference between 4k @ 60 Mbps and 100 Mbps on a large screen, watched from the right distance (meaning just 1m for a 50" display) - which I doubt seriously - please do not forget that if your plan is to use 4k for 1080p projects (and use pan & scan cropping on the 4k material) - than those cropped "windows" will most certainly look better with much less compression artefacts visible if they are 100 Mbps.
But as I said - having experience on various bitrates on my nanoFlash (and that is for 1080p) - I am 100% positive that even full-frame 100 Mbps will look better with lots of "micromotion" (foliage in the wind, water splashes and waves, and alike).

Re: AX100 Firmware 3.0 is out today!!
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.... :-) )

Re: AX100 Firmware 3.0 is out today!!
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.

Re: AX100 Firmware 3.0 is out today!!
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. Mark |

Re: AX100 Firmware 3.0 is out today!!
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! |

Re: AX100 Firmware 3.0 is out today!!
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.

Re: AX100 Firmware 3.0 is out today!!
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. Mark |

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

Re: AX100 Firmware 3.0 is out today!!
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.
