My script and encoding process is using the memory. All of it. I put the laptop on Turbo mode and let it run all night. Memory usage is pretty stable as it processes the video; so if it starts fine, it should continue fine. Unless "system hang prevention" has a word in it.
and if one of the plugins has a bug and it really freezes, then I'd want to know.
Disabling nohang allows it to go about twice further before being killed again.
Memory usage is pretty high, but that's on script start. It remains stable.
I'm wondering whether zram can cause issues by letting VapourSynth think that it can use a lot more space for cache? I'm playing around with cache settings. But anyway; memory doesn't go up, it just decides to kill it at some point. Perhaps at some spikes. It goes up and down in spikes.
Now I'm playing with thread count of both VPY script and FFMPEG, and max_cache_size.
What's strange is that I was running the same script on Windows on 5K footage with x265 encoding. That was hungry. Now it's only 2.7K with x264 encoding.
It starts at about 2.6fps and then steadily go down to ~.8fps when it crashes. Now I see that "swp" in htop was in the red. If I reduce the thread count, swp has some room and it should avoid the crashes, but at lower performance. On Windows I ran 5K footage with x265 at about 0.5fps
Denoising raw cilp... it's too noisy due to lack of lighting, and it does a very good job. Normally it would take 4.5h per 9m clip segments in 5K ... but instead, now it's taking 9h per 9m segment in 2.7K at 60fps. Shouldn't be that slow.
ok so they are not raw files they are gopro files?
what output size quality are you after ?
you say h264, h265 to be able to view on say youtube?
edit why do you think it creates 4gb file of only 9min,s?
it will be for YouTube. Still tweaking the way I configure it. I want above 1K... but 2.7K is only 60fps not 30fps, and that's not suitable indoors with low light. Otherwise it's 1K or 4K in 30fps. It just encodes at standard bitrate no matter the settings it seems; with an option to increase bitrate even further. Fine.. just need to re-encode them afterwards. Then as I'm doing the montage, there seems to be 1 or 2 frames off when switching video compared to the separate audio track...
Then it has wrong VUI tag saying it's TV-range when it's PC-range, video time doesn't account for time zone, h265 encodes with errors...
