Struggling to play holiday video taken on Oneplus 8 PRO

[JN-]

This is Mediainfo of my CFR version. Anyway main thing is it works. Nice show.

VP23 ..
shows end clip position at 13:33;28f
I see now that the audio is at 13:35;24f

So my conforming did this but mediainfo of original is 13:35 when VFR. I wouldn't sweat it anyway, it plays aok.

How did you determine that my file was too damaged when I previously stated that using clever FFmpeg-GU to check for errors in the file, it reported no issues with the file itself?

When I was working with your video.
I first tried a conversion from CLI with FFMPEG.
I got these errors:

Then with Clever I trued to encode the video stream & got thes errors:

It was after that that I used mp4muxer-0.9.3 to demux & then remux the file.
I believe I was the first to suggest the demux then remux approach.

I worked with the first video posted at https://gofile.me/7qEs1/zTD8rwFpJ.
For me this create a file 10minites 17 seconds duration.
After videoAI posted this:
I tried Clever.

I used 2 tools:
1- clever FFmpeg-GUI for stream extraction, multiplex to mkv
2- Losslesscut for container change back to mp4

* the video & audio are 13 min long

I still got 10minites 17 seconds duration from the https://gofile.me/7qEs1/zTD8rwFpJ file.

Then I downloaded the https://www.dropbox.com/scl/fi/f1ji9bxj3folvgvfadf95/VID_20250909_220502.mp4?rlkey=tic...=wt0l8waq&dl=0 file.
Using Clever Stream extract I demuxed this video. Then Multiplexed it.
This gave the 13 minute 35 second duration.
I was able to go strait to .mp4 with Clever.
So I did not need " Losslesscut for container change back to mp4"
With it I got the 13 minute 35 second duration.
The second downloaded file plays correctly in VLC & both MPCs.

Re the differing lengths, the original GoFile is 14min 2sec, whereas the Dropbox version is 13min 35sec.

@ Alwyn,
How did you determine the legnth of the GoFile ?
Maybe something went wrong with the download I did.
MediaInfo shows:
Under General 37 hours 11 minutes
Under Video as Duration 37 hours 11 minutes but the Source duration as 14min 2sec.
Under Audio both at 14min 2sec.
The size of the GoFile I downloaded is 1.44GB.
Both Muxer/demuxers I used show 10 minutes 17 seconds when finished.

This is the first time I have seen MediaInfo have Source duration.

I'm downloading the GoFile .mp4 again as it says it is 2GB.
If the download is that size then something must have went wrong when I downloaded it the first time.

Good Day, Cholla, AVISynth and Magix Video Deluxe both gave 14min 2sec for the GoFile. The one I downloaded was 1.96GB. It gives the 37 hours but also the 14min 2 sec.

Your download must have stopped short?

Your download must have stopped short?

That's what I'm thinking.

I only downloaded the 2nd. Dropbox version when I heard the 1st. one was slow.

[Alwyn]

They are different videos. The filenames give it away.

[JN-]

So it has a video and audio duration of 13:35.
After conforming to 30 fps cfr before extracting streams and muxing it changes to 13m:33s.

The conforming process shortens the video by ~ 2 seconds.

[JN-]

I just now realised that it's unnecessary to extract streams and mux.

Once the original is simply conformed to 30 fps from vfr to cfr it plays fine in both vlc and mpc video+audio.

So all OP needs to do is conform originals. Shutter encoder, Handbrake etc can do that.
