Hi
Looking for critique and suggestions for hdv to web hd workflow. I like
vimeo... results:
http://vimeo.com/4684883

dvgrab -a -f hdv

Load clips and render to 720p Quicktime for Linux using translate,
deinterlace and sharpen

yuva 4:2:2 planar file is  apr. 5 GB per min
uncompressed rgb is apr 10 GB per min.

Edit and render Quicktime for Linux.

As per this very informative thread:
http://flowplayer.org/forum/7/12671
I got pretty good h264 results.

mp4 from yuva 4:2:2 is apr 15 MB per min
mp4 from uncompressed rgb is 30 MB per min

the ffmpeg comandline is:

$ ffmpeg -y -i 720-yuv-test2.mov -acodec libfaac -ar 44100 -ab 96k -vcodec
libx264 -level 41 -crf 20 -bufsize 20000k -maxrate 25000k -g 250 -r 20 -s
1280x720 -coder 1 -flags +loop -cmp +chroma -partitions
+parti4x4+partp8x8+partb8x8 -flags2 +brdo+dct8x8+bpyramid -me umh -subq 7
-me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq
'blurCplx^(1-qComp)' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6
-deblockalpha 0 -deblockbeta 0 vimeohd2.mp4

It ended up being a bit choppier than I had hoped and there is a small audio
delay.

Where I was not sucsessful was trying to render mpeg2 with cinelerra as per
crazed mulehttp://
crazedmuleproductions.blogspot.com/2007/06/beginners-guide-to-exporting-video-from.htmls
Audio rendered but video crashed with errors.
Is mpeg any better than x264 ?

Suggestions?

Kind Regards
