Mpeg streamclip vs. compressor 3.5 ( mpeg streamclip 100 times faster)

Question

(I also posted this in another thread, but i hopes that it gets read, i'm posting it again...)
I'm working on a mbp 2.66ghz with 4g ram, compressor 3.5. Last night I set up a batch of 6 1440x1080 prores 50i clips (each between 5 and 10 min long) to be encoded for web streaming. The exact specs for the encode are here:

I woke up this morning hoping to be able to watch the clips, and compressor was still chugging away on the first clip - and telling me that it was still going to take 36 hrs to finish.
exasperated, i quit the process.
I decided to try encoding with mpeg streamclip 1.9.3b2. I chose the same settings:
h.264 , multi-pass, 4Mbps @ 90% quality (ok, not 8Mbps like compressor, but 8 was still fast in mpeg streamclip), de-interlace, same frame size, yada yada.
mpeg streamclip did in 5 min. what compressor could not do overnight, and the quality is not bad.
what gives??

Answer 1

will my files still be de-interlaced if I turn frame controls off?
