Personally, I would go with a lossless video format.

I find that doing anything with avfs can be very slow for previewing or any sort of response time. Depending on your system specs. Last time I tried was on a very poor machine.

With lossless video, if you have the space, you won't get as much of a strain on performance, especially when you want to do live previews of your editing.

For all work I do with anything, I like to keep a spare 1TB external HDD around for lossless intermediates.
