Videos Playback is longer then video Files stated Duration?

[shoegod49]

I have a video file I am going to be editing and enlarging. The problem is every program i open it in including Davinci Resolve, Handbrake and even MediaInfo state that the video duration is less then 1 second but if I play the actual video in MPC-BE it shows the duration in the slider as zero but the video keeps playing. Also if I right click the video in MPC-BE and select Properties and Media Info it shows the source duration is actually almost 4 mins long but the media duration is 116ms. How can i fix this issue? I've attached a screenshot of the Media Info screen from MPC-BE. This seems really strange that even MediaInfo doesn't know how long the video is.

Try remuxing the file, that may fix the problem.

With ffmpeg the command would be

ffmpeg -i input.mp4 -c copy output.mp4

Alright I'll give that try right now.

How do i run ffmpeg? I downloaded the file which was a 7zip file, extracted it, went to the folder it got extracted too but there are no .exe files. There is a .bin folder which contains ffmpeg.bin but I can't run it. I'm on Windows 11 and i downloaded the Windows version.

You downloaded what from where? It should contain ffmpeg.exe.

I assume windows is still hiding file extensions. Put a copy of the video in the \bin folder, open a command prompt there and try adding .exe to the command.

ffmpeg.exe -i input.mp4 -c copy output.mp4

If you're not familiar with command line programs try using a GUI front end for ffmpeg. Like ProWo's Clever ffmpeg GUI.
