Lossless Scaling LSFG + 48 FPS video is insane

I will also note that unfortunately the Radeon 6800 is not exceptional for video encoding compared to Intel's GPUs or particularly Nvidia's recent high end GPUs. The top end 4000 and especially 5000 series Nvidia GPUs have made massive leaps in video encoding performance.
It should be fine for 1440p upscaling using LSSFG's lightweight optical flow accelerator based interpolation as long as you use a low and consistent multiplier factor.

From what I’ve seen on YouTube, most people recommend the 6600 or above to achieve proper LSFG at decent quality. Video encoding is not the issue for me, as I could still do that on my 4080 Super (AV1 especially) without noticeable performance loss — I already do that.
Basically, I would use the 6800 only as the FG GPU. Apparently, AMD has their own FG now (AFMF or something like that), so there may even be different avenues towards the same goal.

I am currently ill, and until the holidays in May, my job will keep me very busy, but if I try that stuff, I will report back.

I can concur... Video works better in Steam's Vint if you have da deluxe works of enough insanity of GPU compute power.

Steam Vint can do RIFE interpolation on video files, which looks much better quality than LSS.

LSS = better for games (can do video, but Vint seems to do video better)
Vint = better for video players (doesn't do games)

While I prefer organic frames, and Hollywood FIlmmaker Mode for movies, there's a time and place for "framegen-based blur busting" approaches. I have purchased licenses to both. I also have a New article on Steam Vint.

Ok, so maybe this just looks better to my eyes but I just discovered a bit of a trick.

If I am on youtube and watching a 30 fps video, I can put playback speed up to 1.20x or 1.30X and it doesn't distort the audio noticeably, but it does give me an additional 3 base FPS to do frame generation from. It also seems to prevent bandwidth of the stream from dropping on low light or low detail scenes preventing more severe macro blocking.

When I engage LSFG I can get a generated 66 FPS with 2x or 112 at 3X on a 30hz video. Interesting way to bypass some of youtube's crappier limitations.
