Hello All,
New to the list, greetings all around.
I've been using cinelerra for a while and it is working pretty well. I
am currently using Monty's code on a 3ghz 4core AMD machine with 16gb ram. My
source video is from a Canon T2i 1920x1080 24p.
I find that gets a bit tedious if I do more than cuts only editing, so
I
thought I would experiment with proxy files. I found some info on that and
transcoded my file using: ffmpeg -i MVI_0157.MOV -s 1920x1080 -vcodec dnxhd
-b:v 240M -acodec pcm_s16be intermed.mov
The resulting file works fine in mplayer, and ffplay. When I import it
into Cinelerra I see the squiggly lines for audio, but the video frames are all
black. Any obvious PEBKACs in the above? I did a grep on DNxHD in the source
and
it shows up, but I haven't looked to see if it is actually supported (not sure
I
would be able to tell). I also started to cinelerra from the command line to
see
if is spit out any info on what was happening, but I saw nothing that looked
like an error.
Any advice on how to track down what is happening?
Here is the metadata output from ffplay in case that helps.
