i have serious issues with repackaging mkv containers to mp4 for xbox 360 playback.....


started with gotsent and the output files were 10 to 15 seconds out of sync..
then i tried xenonmkv and it was more succesful..every output file was now only 1-2 seconds out of sync..
so now i try using avidemux 2.6 and 8 times out of 10 when muxing the file to mp4 i get a error message saying video is too short..(also should be noted when avidemux does work the resulting mp4 file is flawless with no sync issues)




all i need to do is change the container to mp4 without touching audio/video...


any ideas?? and please no ffmpeg i'm new to all this...i have no idea how to use command line...

here is one i did manage to mux to mp4 with avidemux:

You could try mkv2mp4.

[Wazza10]

You could try mkv2mp4.

i will give it a try! as long as it copies audio + video similar to avidemux it should be just what im looking for..thanks man

Frame rate                               : 30.000 fps
Original frame rate                      : 29.970 fps

The change in frame rate might be a reason for the out of synch issue. This is from your first post.

because that would explain why the video starts off fine but ends up being a second or 2 out of sync

how would i fix that?

[Wazza10]

hey ok so..if i can find when the framerate changes could i split the video into 2 parts to fix this issue?? when i use avidemux and it says files too short...theres still an output file saved its just not the full video...so do you think it would work if i keep that file then try muxing the rest of the video separetly? if that makes any sense lol

sorry so remedial lol.......

[gonca]

The mediainfo in your first post, is it before or after you repack from MKV to MP4?

The mediainfo in your first post, is it before or after you repack from MKV to MP4?

the first post was after repack

[Wazza10]

can you see anything in the working mkv container which would help me identify in the future if avidemux will save the mux correctly?

[gonca]

If you have a framerate and an original framerate which are different you could have issues.
Run the problematic MKV's thru MKVMerge and reset the video and audio framerates to the original values as per mediainfo (29.97 fps)

[jagabo]

Try a simple ffmpeg command. Put this in a batch file called "Remux to MP4.bat" and you can drag/drop video files onto it to remux into MP4.

"c:\program files\ffmpeg\bin\ffmpeg" -i %1 -vcodec copy -acodec copy "%~d1%~p1%~n1.mp4"
pause

Change the path to ffmpeg if you have it installed elsewhere. You might have to specify a frame rate if you get sync problems: "-r 29.97", or "-r 30000/1001" for example. Put the batch file in your SendTo folder and you can right click on any video file and select Send To -> Remux to MP4. You can remove the "pause" but then you won't see error messages when there is a problem. There will be errors if the source file uses codecs that aren't compatible with the MP4 container.
