Number of frames change after converting

[vivabarca]

Hi, after convert mkv to mp4 (with mkvtomp4 0.224) the exact duration is changed:

mkv:


Mp4:


..
I have to convert mkv to mp4 to import in Premiere and the total number of frames is important for me (exact duration of video must be untouched), I tried other ways to convert mkv to mp4 but there is same problem.

Any way to Prevent this Difference?
(I Just need convert to a format that premiere Accepts it. mp4 ,avi ,ts or ...)

It's a difference of one frame. I doubt it's anything to worry about, probably just something like the end of the display duration of the final frame being counted as an additional frame for MP4, or something like that.

Who's counting the frames? I tried remuxing an MKV to MP4 with ffmpeg and checked it with Bitrate Viewer. The total frame count was reported as the same.

Another method you can try..... Download ffmpeg and AnotherGUI. Stick ffmpeg.exe in the same folder as AnotherGUI. Create a preset for ffmpeg to remux as MP4 by adding the following to the first pass section:

-i "<FullSourceFileName>" -y -threads 1 -vcodec copy -acodec copy "<OutputPath><OutputFileName>.mp4"

Save the preset and drag and drop any files containing MP4 compatible video and audio onto AnotherGUI and click the Go button to remux as MP4. You can change the output format by simply changing the output extension in the preset. The video and audio have to be compatible with the output file type when copying them though, or you'll probably see an error.
