Hi everyone, today’s 6.2 release for Video AI includes improvements to EXR handling, RTX 5000 series optimization, and support for Google and Apple single sign-on.
Thanks. Short tested in V6.2 frame interpolations with different output codec and models. Input test-file was 25fps h264 mp4, produced no VFR. Output was set to 50fps, everything fine. Then I took FFV1 source and did Aion 50fps and MediaInfo shows VFR. The same file with MKVToolnix remuxed into MKV container and Mediainfos says it’s constant framerate, as it should be.
So TVAI produces no VFR but something happens wrong with container tags, pending on input file codec/format. It’s not a big problem, but when other programs reads out fps from container, worse things could happen. To reproduce import ffv1 source into TVAI, do frame interpolation and check result with MediaInfo.
Left shows VFR with crazy max fps, on the right the same video after remuxed into mkv shows CFR
It adds entries into the preview menu and they all complete to 100% and “done”, but nothing ever changes on the screen to the right (Where the preview always was in earlier versions)
And when I click “Show in explorer” nothing happens.
I can’t even clear the cue (All entries just remain)
Preview still doesn’t work with ProRes 422 HQ, unfortunately. I’m not sure if this is a known issue; it could just be a personal problem.
Also, the timeline scrubber isn’t aligned with the increments and has weird, glitchy movement when you hold the left click on it.
Also also, preview doesn’t work in general sometimes. ProRes, H.265, H.264, doesn’t matter; it turns green on the bar, but then it just turns gray again as if I never even clicked preview. It might be a problem with my footage. I export with ProRes 4444 XQ; I’ll try with ProRes 422 HQ. It happens when I export with AVI as well. However it does work when I use the “Render In > Out.”
Same problem here and not only with ProRes; Preview V6.2 seems generally broken. They gets generated, but not shown into TVAI. You have to open TVAI preview folder and play the preview files in your player.
Some good news: The benchmark for 6.2 says that Nyx runs at like 6.4 fps on my system, where it was running at like 9.8 fps. Processing real videos, it would usually get around 9.3 fps. I just did a test and it was able to get 9.6 fps, so 6.2 has not regressed like I was worried about.
Interesting video. Is the presenter correct that TVAI for macOS isn’t utilising the hardware encoder/decoder engine? This would seem to be a bit of an oversight if true and could make a huge difference to throughput.
I can see it being something that you have to pay Apple to get access to development resources for—something no one in the ffmpeg development community is going to do.
When trying to download the stabilization model via the model manager, I get an error that says “Error: connection handling cancelled”. This happens when gpu (4090) and auto are selected for the device.
A quick look at the ffmpeg command line is enough to show that Video Toolbox is being used whenever possible for hardware encoding - h.264/5 (HEVC) and ProRes. Also, there is no additional GPU / CPU usage shown when those codecs are being used, which also indicates encoding is being done in hardware.
