As mentioned by others, Windows 7 and older and 32bit Windows are not supported now.

I cannot update the first post because it is posted by another person.

Version 21.2.1 is released

Version 21.2.1 is released.

Others
  • Excluded utv_logc.exe from installer.

License (GPLv2) / readme / Windows exe installer zip package utv_logc.exe / source code / GitHub

In addition, experimental zip package is available. I don't explain the usage of zip package more than written in readme-zip.txt .

FIX: In uninstall procedure, the batch file to execute is uninstall.bat. Not install.bat (written in readme-zip.txt), of course.

Thank you it's the best codec for realtime encoding !
UTvideo T2 is the fastest.

It is supported on ffmpeg ? Or only T1 in FFmpeg ?

As far as I know, T2 encoding is not supported on FFmpeg. T2 decoding is supported.

Hi, Thanks for your codec, it is amazingly fast.

I feel that the "Not recommended" about interlaced video is a bit brutal, because if really encoding Interlaced Video we dont know if we need to use it.

Is it not recommended for progressive, not recommended at all ?

At the moment i'm working on Interlaced video I dont know if I must/need/should check it.

Not recommended is for allways checking this whatever your video is. Otherwise it will assume video is interlaced, and encode accordingly, wich will result in less efficient for progressive video.
If it's always checked, encoding of progressive video will be less efficient.
If it's always unchecked, encoding of interlaced video will be less efficient.
If you think there is more progressive than interlaced videos, you'll not recommend the interlaced mode.
The best is to check it when you have interlaced video, and uncheck when you have progressive.
If you're dealing more often with interlaced than progressive video, and don't want to have to configure each time, it will be more efficient to check it.

The reason I wrote that the option is not recommended is simply because it is slow and I won't optimize it anymore. There is nothing wrong with using this option if there is any reason.
  • If you are working with interlaced video, you can achieve higher compression ratio with the option.
  • If you use ULY0/ULH0 and its input/output format is not YUV 4:2:0, you should use the option correctly because vertical down/up sampling algorithm depend on whether the video is interlaced or not.

Of course, you should not use the option if you are working with progressive video.

Maybe it would be better to label the interlaced option as "slow". It is obvious that the option should be used only for interlaced content, but as things stand the user might assume that it is not recommended even for interlaced content, or that there is some issue with interlaced video in UT VIdeo, which is not the case.

Maybe "Don't enable by default" or similar...

Does ffmpeg include the official codec, or do they have their own UT-Video implementation?

Edit:
I seeem to have a major issue when trying to record with MSI afterburner. No video is recorded.
