MP4 container video length info is blank

Sun Feb 08, 2015 10:53 pm

After editing and merging sections with Bandicut - when using mp4 container videos - using lossless for the merge, video length info is not maintained. It displays 'blank' info in WinExplorer.

Using the MediaInfo App the video length info does disclose correctly for the mp4s.


If however, you use avi (source) and perform the same editing and merging as above, the video length does show the correct video length info. :|

Hi SnQQpy,

After editing and merging sections with Bandicut - when using mp4 container videos - using lossless for the merge, video length info is not maintained. It displays 'blank' info in WinExplorer.

=> Can you play the video without any problem?

Using the MediaInfo App the video length info does disclose correctly for the mp4s.

=> Could you please let us know the information of the MediaInfo?

Yes - video plays without issues. I did a small test for this purpose I can send it to you if you email me, its only 19KB. :)

Please note this issue is not size or length dependent though. In the original conversion when I noticed the issue its 1GB.
