No, FLV1 movies under 350 Kbps will never be re-encoded.

They do not re-encode them, you can read:

The thing is I'm creating script that will encode uploaded movies automatically.
So, visitors of my website will upload their movies and I don't think they will
do such things as pan&scan.

I can make movies viewable, but what I really want is to get highest possible
quality which is:
448x336 resolution
15 fps
bitrate close to 350 Kbps (including sound)
