I would really, reaaaaaallly suggest using a modern NLE for modern cameras instead of trying to stay with the older software and transcoding everything. Resolve is getting there editing wise and it also has built in Fusion now for effects and Fairlight for audio. Also the basic version is free and probably does enough for your needs.
If you’re used to doing effects in AE you could render out some supported format from Resolve and work on the shot in AE. That’s pretty much what I do most of the time.
[Norman Willis] “Would you recommend Handbrake and YUV Lossless AVI?”
Not really. There are a bunch of good “visually lossless” formats like Prores and DNxHD but if you’re on Windows it might be tough to get them working as Quicktime has been killed and every program has their own encoders/decoders for that now.
