vk.com is not fixed

Ant detects mp4 and aac files, sometimes the mp4 already has sound, sometimes need to merge, other times the 720p has sound but 1080p need to merge  but anyway the final file is unwatchable, it hangs on the player or goes too fast, things like that
Oh, and the conversion reduses significantly the size of the video

Any update on this? New beta did not fix it

See the size of the video before and after conversion and try to play the final file in your player (It's not a codec thing)

My MPC-HC 1.9.8.21 (https://www.codecguide.com/)  plays this video fine!
Synchronization of audio and video is good. Conversion by mpg.dll (from AntDM internal converter)

ok, I could reproduce your issue.
- fox Video Box: ffmpeg.4.1.1 that is currently used in our project does not cope with the correct conversion of such videos.
- fox Video Button: it captures HLS stream and it works fine.
- you can download and try to use the new experimental AntDM.x64 build. It uses ffmpeg 5.1.2 and this should work for this video.
