xeddin1 No problem, Its not a secret haha.
I made a little program in Python that uses ffmpeg to cut videos. You can download the 8K h.265 version of an SLR video and use it without issues. As I mentioned before, you can cut segments of several minutes in just seconds (the last test I did, cutting a 10-minute segment, also took 2 seconds lol).
I can upload the code to GitHub or Google Drive and share it with you, but I would need to explain how it works. The only inconvenience is that you need to manually modify the start and end times of the clip in minutes, seconds, and milliseconds each time you want to trim a video, with no frontend, editing the code manually.
Luckily, I managed to make the program recognize other details like resolution, encoding, FPS, etc auttomatically.
Now I'm trying to create another program that is capable of putting the videos together with some simple transition to get started without having to go through the editor. Let's see how it turns out.
BTW what program do you use for editing video, im using OpenShot, and I hate it 😆
