3 second video freeze at beginning of all converted MP4 to MKV

General Support / Questions

I’m having an issue when I convert HEVC MP4 files to MKV using the below MKV Unprocessed profile. When I play the output file the video is frozen at the frame about 3 seconds in until the audio catches up. I’ve verified on both MPC and VLC. This does not happen on the original MP4 and if I do a ffmpeg -i <inputMP4> -c copy <outputMKV>.

The PrecustomCommand is only to ensure that the srt or vtt is valid based on extension and move it to destination location as I don’t need them processed in MCEBuddy.

Will upload sample files when I get ftp to work.

I have had this issue for years. When MCEbuddy converts a file from mkv to mp4 there is a 3 or 4 second video delay the audio plays but the video is just frozen for the first 3 or 4 seconds. Never have gotten a resolution for this problem.

Try checking the Skip remuxing option in the Conversion task → Advanced options

You can now upload the original video, our server was down for maintenance

That resolve it. Thank you
