GoPro, Editing, & Rendering

Here is what I am running into. I film something with the GoPro and want to trim and speed it up or slow it down. I usually use the 720 60p format. Given that it is already a highly compressed file when I drop it on the timeline here are my questions:

1. What format (other than uncompressed AVI) should I render out to that is timeline friendly and compression friendly? Sometimes I use BCC7 Optical Flow to speed it up- render it out and then apply Optical Flow again to further speed it up (the first render was maxed out at 1000 velocity). The last one was 4 hours crunched into 3 minutes but it took 2 renders- the first render brought it down to 12 minutes and the second I adjusted to 3 minutes. Perhaps there is a better way to do this?

2. Other than adjusting levels for Vimeo, is there anything else I should adjust? Render template custom settings? I am having "Vegas encountered an error" issues when using Sony AVC with an mp4 extension so I have been using MainConcept to render out the files.

3. I was using handbrake when using HDV but that seems like an additional render to add to the mix coming from a GoPro when I can render out directly to mp4 for Vimeo. Should I be using some sort of intermediary file? I know that Cineform was bought by GoPro... however, I didn't own it before the buyout and I don't own it now (except in a previous version of Vegas).

Suggestions?

3. As CineForm is free for GoPro users, not really an issue for buying anything. Download it today http://gopro.com/3d-cineform-studio-how-it-works/

Thanks David, I will download it. I thought it was just for the new 3D package. Thanks for the heads up though.
