Hi all!
First of all I'd like to introduce myself: My name is Ansgar, I'm from
Duesseldorf, Germany and I'm still new to Cinelerra, though I've spent a fair
amount of time with her so far, compiling once (on openSuSE 10.3) and
installing twice (2nd time from rpm on openSuSE 11.1).
I haven't actually begun to work with cin yet and that's because playback is
crippled to 10 - 15 frames per second, which is not usable (my hardware:
AthlonXP 2000+ processor, 1.5 GB RAM, 250GB HDD, graphics not worth
mentioning - but I don't need 3D-acceleration for cin, do I?).
Someone on IRC (can't remember who) suggested, that this might be, because I
use MPEG2-video on the timeline. Indeed I imported the .vob-files directly.
So which format will make cinelerra happier? Which is her "native" file format
to work on? And, most important: How can I create it / transcode .vob's into
it?
I understand that the lesser the compression, the better playback should be.
So I've tried avidemux (which is a great tool!) and turned the vob's
into .avi containing "YV12 (raw)" streams - but cin wouldn't import the file.
Is there another codec that you would suggest?
Or is it the AVI container format that keeps cin from performing?
I'm prepared to use transcode or mencoder from the commandline, but I just
can't figure out which options I should use. :-(
BTW: After editing I transcode my video to X264/mp3.
Greatings, I'm new too. I've successfully edit a 3 minute demo within
the last week.
I have had very bad experience with anything other than MJPEG. I have a
Quad Core 2, 4GB RAM, with the -smp version running. MJPEG makes it a
dream to use.
Tweaks to what Raffaella suggested last week, you might try something
like this:
mencoder inputfile.ext -vf scale=720:480,harddup -demuxer lavf -oac pcm
-ovc lavc \
-lavcopts
vcodec=mjpeg:vhq:vbitrate=12000:nr=400:vqmin=1:vqscale=0:mbd=1:aspect=4/3 \
-noskip -mc 0 -o mjpeg.mov
Then import that into Cinelerra.
-----------
To the developers:
This may sound short sighted, but -- with Lumiera or current development
could you consider JUST enabling media formats that work? So many
unstable imports and exports causes so much confusion with new people.
I was also wondering if Lumiera would make use of GStreamer?
Thanks,
Scott
