Well, cinelerra _should_ be able to handle your files just fine. I
assume they are just too big.
If that is the case, my workflow was always to convert the files to
mjpeg at a usable resolution ahead of time, then edit the files, then at
the very end I would copy the edit.xml file to edit_large.xml and
change all the file names and sizes back to the original filename and
size with a text editor and some simple search/replace. Then,
I'd render out to my preferred format and go for a long weekend at the
beach while it renders on my little 600mhz machine intel pII
here is the convert script I used to convert to smaller sizes in a
folder named "convert":
-------------------------------
#!/bin/bash
# change this so that the ratio matches your 1080
SCALE=640:480
mkdir -p convert
for FILE in $( ls *.avi); do
echo item: $FILE
# MAKE sure to use -vf harddup for cinelerra
mencoder -o convert/$FILE -oac pcm -ovc lavc -vf \
harddup -lavcopts vcodec=mjpeg:vbitrate=20000 -lavfopts \
format=mov $FILE
done
-------------------------------
best -august.
