  • 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!

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

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

  • @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

  • @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?

  • @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:

  • @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 really a tutorial, it more like Cinelerra Chroma-Key The Music Video.

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

  • @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...

  • @Director84 Fuck you.

  • Not having sony vegas makes me miss windows :(

    Owell Linux is so much better for many more reasons.
