Are you sure it's overwriting (replacing) frames and not creating new ones? I've done this before, but it so happens that the frames I was replacing were silent anyway, so I wouldn't have noticed if the sound had been overwritten. > > You could > > use mplayer to dump frames and then insert frames from the FX tab's > > multiple image import to overwrite just the video and leave the audio. > > Okay, I have no idea how to use mplayer to do this, nor how to just > overwrite the video. "mplayer -vo png yourmoviefile" will dump each frame as a png image. You can use the "-ss" option to seek to a certain position in the movie (it's not terribly precise, but works OK), and the "-frames" option to control how many frames to dump. > Okay, I've downloaded the smilutils, but haven't gotten to the point of > using them yet. They work quite nicely. That's what I use for all my DV conversions now, and they can pull the audio as a wav or as an mp2. > Do you have a short tutorial of what buttons you press to do the video-only > overwritting? Also, how to use a frame from the existly playlist as the > overlaid image? If you're overwriting with a single frame (a held shot, for example), it's easy. Load up your video, go to the point where you want to overwrite the held shot, then use the "ImageMagick Overlay" FX to overwrite the frames. That's the short version. Longer version is this: Use the VCR controls to get to the point where the frames should be overwritten. Position it so the first frame to overwrite is visible. Now pull down the "Commands" menu and choose "Split scene". Now move it to the last frame to overwrite, then forward one more frame (so you're on the first frame *not* to be overwritten). Split the scene again. So now you should have a scene that consists entirely of frames to be overwritten. Select the scene (click on the thumbnail for it). The first frame to overwrite should now be visible. Click the FX tab. Selecte the "Frames" subtab and then the "Overwrite" tab. It should already have the correct options, just make sure the "limit to" button is NOT depressed. Now click the "Image" subtab. Choose the "Filter" tab, and change the drop-down option to "ImageMagick Overlay". Click the "Browse" button and select the image to overwrite with. Leave everything else at the defaults. Click "Preview" if you like, then click "Render" to do the deed. Kino will create a new video sequence and insert it into the edit list in place of the frames you selected. Your original video is NOT modified (which I *really* like), just the edit list. Then when you pump the edit list through the smilutils, you get the edited video. You can then mplex that back together with the original audio and you're all set. > Thanks again, > Bill No problem. I am a relative newcomer to all this stuff myself, so there may be easier way, but so far I can make it do what I need without much trouble. -- Robert Kesterson [EMAIL PROTECTED] ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
