Windows 10: Error using Photos to trim MP4 higher than 4K resolution

I can use Win11's Photos app to trim MP4 files as long as the file is not higher than 4K. For example, if the MP4 is 4096x2048, I can trim, but if I try to trim an MP4 file that is 4320x2160, I get this error: "It looks like you don't have permission to save changes to this file. Try saving a copy instead." When trimming, my only option is "Save a copy". The MP4 files are stored in the same USB external drive. I make sure the files are Unblocked and I have Full permissions on the files.As I've stated, the only difference I can see is if the file is 4096x2048 or lower, I can trim the file.

Trying to split MP4 in Photos app - trim is grayed out

I'm trying to split an MP4 in the Photos app - but trim is simply is grayed out.

I can play the MP4, but nothing else.

In fact all the edit+create options are grayed out. I could have sworn "draw" was available, but now that I look again, it's not.

 

Video trimming is not working

Hello, I have tried to trim a MP4 file using both Photos and Movies & TV.

After I choose a part and click "trim", the trimming window closes off by itself and the trimmed video is saved but does not play/show anything.

I tried again and again with other MP4 files but it does not work. Please help.

Thank you.

 

Nokia N86 - AVI/MP4 with higher resolution

hi, I have a new N86 - very pleased with it do far. One thing I'd like to do though, is use the TV-out to play video files on a TV almost like a DVD player (eg to watch a film in a hotel through the phone). It works for "normal" MP4 files that have a resolution
less than the mobile can view, but it didn't play a higher resolution clip that would be needed to get a decent picture on a TV. Is there anything I can do about this? I think I saw somewhere that Coreplayer may be able to play AVI files around 700mb, which
may do it.
