I think it's an ideologic question, but I would choose VP8 and make a
preview with speed=2 and the end-rendering with speed=0. For quality
rate you have to try, because it also depends on your input data (Maybe
start with 6 for the "ugly" and go down to "3.5" for the nice one?).
But also Theora would be good enough for preview. I just can recommend
the use of Matroska (MKV) and Vorbis.

Fortunately I only needed to crop some bits (no transitions necessary) out of an online MP4, which I was able to accomplish pretty speedily after `sudo aptitude install pitivi` (on a Mint box) and a bit of reading of the "manual." I now have a 45-min version of an original that was ~90 min (and 400 MB). At least, I now have that in pitivi ...

Ultimately I want to show this video on a large monitor at an upcoming public meeting, so I chose what seemed to me to be reasonable rendering parameters: video=XGA, audio=CD, and container=mp4mux (taking the container defaults of lamemp3enc and schroenc). This produced a render time=20 hrs (I'm also doing this on fairly lowend hardware), so I decided I should do a quick-and-dirty proof-of-concept first. I chose video=QVGA and twiddled the audio and container parameters to favor performance over quality, until I got a render time=2 hrs, which seemed reasonable.
