Another useful use case is that the tool works on videos with mpv
to interpolate to a higher frame rate. I know that subjectively not everyone likes that for film, but for footage that doesn't rely on sets and the like such as sport and Youtube videos it's a nice improvement.
In terms of quality vs performance, I'd say it's somewhere between the lower quality SVP default and the higher quality (but very resource intensive) RIFE implementation. There's also LSFG_PERF_MODE=1
and decreasing the flow rate, but the former was a pretty obvious decline in quality, but might be needed on slower GPUs.
Neither Reddit nor Lemmy are monoliths. Yes, some are likely being hypocritical, but it's also likely that there isn't much overlap between those that were critical of Nvidia's FG and not of LSFG. I say this because there is still a lot of people shitting on FG in general, whether it's justified or not.
