Editted files don't work in TV app

[Formshift]

I editted several MP4 files, but most of the editted files will no longer be accepted in the TV app. The uncut versions were accepted with no issues. Is there any way to see what part of the MP4 causes it ? Thank you.

The built in player in most TVs are pretty bad at playing files that have been cut, especially not keyframe cut clips. You may consider using another player on your TV like VLC, Kodi, Nova, etc using an Android device to get the best playback.

By TV app I meant the TV app from Apple in MacOS. I don't want to use other software since that is what I use to stream all my media to my AppleTV.

Make sure your clips are keyframe cut or it won't play. If they still don't play, you have no choice but to use a player that works.

They are keyframe cut, yes. When I do the cuts in Quicktime X, the TV app does accept the file. So it seems like lossless-cut does something that the TV app doesn't accept.

Then as I said before, you have no choice but to use a better player than the TV app. I don't have any issues playing keyframe cut files on the 4 different players on my PC and TV.

Since that's not going to happen, I have no choice but to use a different editor, or hope the developer figures out what the issue might be.

what is the tv app? iOS? Macos? apple tv? and what kind of file (codec/format)?

[Formshift]

The TV app on MacOS. When I drag and drop the files, or put them in the watch-folder "Add to TV library", it doesn't get added to the TV library. The uncut versions get accepted just fine. They are MP4 files with an H264 & AAC track.

Ok I managed to reproduce the issue. When drag-dropping the cut file, nothing happens.

I managed to track it down to -movflags use_metadata_tags. When I remove this the cut file works.

This flag was added because of an issue with metadata #99
But there have been other issues due to the flag, so I'm thinking I should make it default false, but with an option to enable it.

[Formshift]

Okay, thanks for figuring this out. Is this something I can disable myself in the meantime ?

You can run your cut, then go to Help -> Last ffmpeg commands and copy this command to the command line, then remove the flags.

...or you can run this command on your output video: ffmpeg -i video.mp4 -c copy -map_metadata 0 out.mp4, but you will lose metadata.

In the next version there will be an option to not preserve MOV metadata (disable the -movflags use_metadata_tags flag). I have also made this the default (flag disabled). This should fix your issue.
