Before spending money on any of these, I’d like some advice. I have a hard time spotting the differences between RIFE-App and Flowframes. Which one to use? Of course, this might be a delicate question for any of the developers to answer as there’s an inherent aspect of being partial (devs: by all means, feel free to share some honest, partial thoughts here, I don’t mind). If anything, perhaps at least users who tried both could chime in with their thoughts and experiences?

For all I know, the comment section on Flowframes seems to include some complaints about dodgy functionality. I don’t know if those are related to presumably older, delayed versions released on Itch in contrast to newer versions you’d get if supporting their Patreon, which seems to be their choice of revenue stream. How is stableness and functionality in RIFE-App in comparison?

Personally, I chose RIFE-App because:

• When I used Flowframes a few months ago to interpolate high resolution video (4k to 8k, especially VR), it required a MASSIVE amount of disk space (not RAM or VRAM, hard disk). Like hundreds of gigabytes. RIFE-App doesn't have this problem.
• RIFE-App's profits are shared with the creator of the RIFE algorithm.

I really can't give my opinion since it would be biased, plus I really don't use other software for interpolation so I can't compare, but feel free to discuss it.

I can just say that right now Rife-APP don't use any more of Rife code. It use a algorithm made by myself, trained from scratch, so it should generate interpolations different from any other software.
