First of all, thank You for the respond. Luma Fusion is my personal game changer at work, so I couldn't wait to finally get an answer
I use different cameras: from Panasonic, through Sony, and now Go Pro from a few days. But I made a small mistake about my post, I didn't record it with Go Pro. I did that with OBS Studio on my laptop, Go Pro was just giving the signal to PC (through black magic web presenter).
To answer Your questions:
- I got over 100 GB free space left, it is a 256 GB version of 2-nd Generation iPad Pro 10,5 inches
- by importing I meant... I saved a video on my PC, copied to SD card, then copied to "Files" on my iPad using a SD card reader. After I got it on iPad I simply drag & dropped it as every other video. I can see it in a preview window in Luma, but when I drag&drop it on timeline, the program keeps processing the file on and on
- the format of a file is a MPEG-4, 30 fps (1 clip in 1 track), 105m49sec long long, 2.1 GB, 1920x1080, avc1 codec
Just in case I will try to delete the video and save it again on my iPad in the meantime.
P.S. Seems like it is OBS Studio files, that seems to be the problem. I checked long, average long and even a 3 seconds long file recorded on my laptop using OBS Studio. All of them have same issue when trying to drag&drop it on the timeline. Any advice on that?
