compress at 50i or 50p?

source:DV
output:XviD Q3 (or x264)
what is better for quality/size (on C2D PC)
1.compress at 50i and get 50p while playing (yadif)
2.deinterlace (maybee better deinterlacer like mvbob/mcbob, compress at 50p
maybee some denoiser like fft3d
?

?x264 is not very efficient at compressing interlaced video, and I don't remember if Xvid supports interlaced or not.

For DV, I would definitely recommend a denoiser. If you have the disk space, compress it as 50p after deinterlacing; otherwise you can always just dump half the frames if you're really short on disk space.

I would compress at 50p if you can afford the disk space.
