Trouble stitching mp4 files together taken on same phone, on same day.

[kklasmeier]

On my phone, I took family videos. Trying to merge them together into a single MP4 file and finding problems in the app.

Check compatibility complains each file is encoded differently than one and other.

Track 0 mismatch: r_frame_rate 30/1 != 30000/1001
Track 0 mismatch: width 800 != 1920
etc.

Furthermore, I cannot determine how many different combinations I have, so I can't even try to group them.

When I view the files individually, they work and look great and they all look 100% the same as each other. Any ideas how I can stitch these together? I have 12,000 files that I want to stitch and I am at a loss given these compatibility alerts.

You could write some script to use ffmpeg to generate a report of all the files and their codec parameters, and then group them based on that. This isn't something that LosslessCut currently supports. Maybe in the future but you're the first persron who requested this so far
