FRAPS to x264 to Youtube

[kutjong]

I've recently started to do video captures with FRAPS. I will also be going to upload a few of them to Youtube. I'd gladly accept some tips regarding the process.

This is how I've currently planned it:

1. Record with FRAPS 1080p in RGB lossless mode.
I understand there are problems with YV12 capture?

2. Avisynth script simply:
AviSource("file.avi", pixel_type="RGB32")
ConvertToYV12(matrix="rec709")

3. x264 settings:
High Profile 5.1
Preset medium
Tune film
CRF 22

4. Upload to Youtube.


Regarding the avisynth script, will this automatically make the video in 16-235 levels? Or do I have to enter another line for this conversion?

Also, the profiles in x264, any point to encode in 5.1 or is 4.1 ok? Will 5.1 encode more efficiently?

Ps. I did find a few threads on this on search but it was hard to get any good or conclusive facts on this issue, other than YV12 encoding in FRAPS seems to be dodgy.
