Re: [CinCV] Help syncing sound to video
OK, after some messing around hitting playback twice isn't entirely useful except for finding a general spot I'm looking for as it's hard to control reliably. However the label method is working out great. I just insert a label where I think I need to be, hit play, and just keep moving the label up until I've gone one frame too far. When I've gone too far I just go back a frame or two and that's where I need to be.

If you hit play then stop the playback real quick (hitting spacebar twice is the easiest way) you can get cinelerra to advance a single frame while still getting it to play sound.You have to time it right too, because if you hit play the second time too fast it will just jump back to the original frame without playing any sound at all. Not quite as convenient as it could be if the frame forward button did this, but it works. By combining this with labels I seem to be able to sync things just as accurately as I was able to in Premiere.

Re: [CinCV] Help syncing sound to video
That strategy just might work for me. I'll try it out and post on the results later. Thanks.

Re: [CinCV] Help syncing sound to video
Hello,
A simple and dirty trick: Edit the sound track, and put claps in the
instances where you want a switch. Or clap hands in the beginning of
each bar (if it's a rhytmic song, the drums do that job for you). It
takes a little work to prepare this, but after this is completed, your
work is easier and more accurate than any other solution.
Hand claps and drums are easy to spot visually in the track's graphical
display, and allow perfect timing matches with picture.
Note that you can safely replace the source sound file ("asset") with
the edited one (on the hard disk) for this purpose, and return the
original back for final rendering (but make sure they are identical in
length and format).
Good luck,
Eli

Hi, I've just started recently getting into editing using Cinelerra
over the past couple of weeks. I've read most of the simple tutorials
and I've searched around the mailing list archives so sorry if this
has an obvious answer.
I'm trying to edit together a music video and the problem I'm having
is I can't figure out a reliable way to accurately sync clips up with
the sound. For example a certain instrument plays I might want a clip
to start playing at that exact frame. Last time I did any video
editing was in an old version of Adobe Premiere where I was able to
accomplish this mainly by dragging the timeline cursor around, as
sound would play as you did this even if you only moved forward a
single frame. Doing that, I could pinpoint the exact moment I was
looking for in the audio and drop the clip in or just watch the video
playback and see if everything was happening in sync. In Cinelerra
however if I press the button that moves the playback one frame
forward no sound is played. As for using the waveform graphic, it's
not very useful for what I need.
So does anyone have any suggestions? For example, is there a way to
control playback speed and just have the preview run in slow motion? I
could export pieces and preview them in mplayer since that has slow
motion playback but that would be tedious.
