Making Movies
How do I export a good quality, small size movie from Premiere?
Method 1:
- Export a 95-100% quality "Motion JPEG A" video from Premiere.
- Compress this large (often ~1GB) file using mencoder and Szymon's toavi script, which is also reproduced below:
#!/bin/sh - rate=1200 #codec=msmpeg4 codec=mpeg4 case $# in [01]) echo "$0 in.avi out.avi [bitrate]" ; exit 1 ;; 3) rate=$3 ;; esac mencoder $1 -vf eq2=1.2:1.0:-0.1:1.0:1.0:1.0:1.0:1.0 -ovc lavc -oac mp3lame \ -lavcopts vcodec=$codec:mbd=2:mv0:trell:cbp:vqmin=3:last_pred=2:turbo:vbitrate=$rate \ -ffourcc MP43 -ofps 29.97 -o $2
- If you want it to play in Windows Media Player, you may need the "msmpeg4" codec.
- I'm sure there is something I'm forgetting about this whole thing...
