Cinelerra Tutorial chroma-key

[jacolmes]

When I try to open a video, it takes just the first second, and there's no audio. I tried to convert it in dv, but cinelerra crashes!

Help!

[Thanatermesis]

@jacolmes recode/reconvert the video to the format mjpeg + (mp3 or wav) and you will not have problems anymore

[Synicade]

In Cinelerra, when I try to view a video, for some reason it's fast forwarded and theres no audio, please help! :(

[Thanatermesis]

@Synicade check your settings in the settings menu, try alsa or oss-envy, even try esound (run esd from a terminal), this will solve your problem, a restart of cinelerra will be needed for every try

[Synicade]

@Thanatermesis Thanks, it's working now :) But I also have another problem, for some reason when I render the file it looks waaaay off. It's like, pink and green, and the file size is changed from 20 MB to 458.8 MB. Any idea on what might be causing a rendering problem?

[Thanatermesis]

@Synicade Do not render using GL mode, and use bilinear or bicubic when render (not when editing, so its faster), use YUV4MPEG Stream rendering so that the quality will be the best, and the audio separated as Microsoft WAV, then use mencoder to mix audio and video files in a good quality compressed result with mencoder:

[Thanatermesis]

@Synicade mencoder command (see the filenames that you need to replace) mencoder -oac mp3lame -lameopts abr:br=128:vol=0:mode=1:aq=0 -ovc x264 -x264encopts qp=20:me=umh:subq=9:nr=100:thr­eads=auto -of lavf -lavfopts format=psp -audiofile audio-in -o file-out video-in

Not having sony vegas makes me miss windows :(

Owell Linux is so much better for many more reasons.

Not really a tutorial, it more like Cinelerra Chroma-Key The Music Video.

[a2zhandi]

ah crap, I gotta learn this one too?

Either way, the software for linux is surpasing windows at lightning speed!

I'll work with it. Great demo!

[sachteau]

Cheese, just follow the moves :D if you have ever used any video editing program you should get the idea, this person who made the tut should tell this is not a beginner tut and no one will say it wasn't useful. If you track visual material you can see what he did. On the other hand, explanations would be good. Just something I wanted to say. ;) *hugs*

[sucka4free]

good attempt to try explain..but not very useful as a tutorial when u don't really say what you are doing

[Thanatermesis]

That is true, sorry, maybe in the future ill made a better video if i have time

[id0069]

I agree with the others about the narration. If you're doing slide demos, maybe you could provide the text on the slides and go thru it slower, or maybe some detail instructions in the comments section. Thanks for taking the time to put it together.

[Thanatermesis]

Sorry, maybe i do a better video in the future

[TheJerico246]

when i try to install cinelerra it says it is not installable

i tried add/remove and synapic manager

[Salvadorenno]

install from source. or reply me if u dont know how

[billfromnet]

You call this a tutorial?

[Director84]

Some explanations would have been a lot more useful than the crappy techno soundtrack.

[adric22]

I agree.. I can't figure out what he is doing. Some narration would have been more useful.

[Sagaramath]

@Director84 Fuck you.

[Director84]

@Sagaramath Why should I? Because I know that a tutorial needs explanations instead of a crappy techno score, to be of any use? Well, given your very intelligent reply to my VERY old comment I assume that you don't know much about tuition anyway, as you've probably never got much of it...

cinelerra rulez

[drakasx]

Hey, whats the name of the track you're playing here?

[Thanatermesis]

Yes, the codecs stuff is the more delicated part for cinelerra, i convert all my videos in a only format, aparently the better for work with cinelerra (no only stability but also performance), this is my script:

mencoder -oac pcm -ovc lavc -lavcopts vcodec=mjpeg:vhq:vbitrate=6000 -o video-output.avi video-original.avi

[profox111]

thanks for info.. will give it a spin.. :)

[profox111]

Nice.. If only Cinelerra would stop crashing on me. Any idea why it always does that ? I do try to import .mov and divx files though.. could that be the reason? should I convert them to something else to get a stable cinelerra?

[jmh1]

Try converting it to a DV file using Kino, any video type other than DV will be automatically converted. You can import the DV file into Cinelerra
