AFAIK, using .wav sound files this problem doesn't occur.

This happens only with .mp3 files with variable bitrate. Cinelerra can't play them back properly: the playback is correct for the first seconds (regardless of where it starts) and then gradually becomes unrelated to time. Seeking is unreliable.

To solve that you can convert to .wav (as Senbee suggests) or, to save disk space, you can create a table of contents (TOC) file to be loaded on the timeline instead of the .mp3 file. To create the TOC file use the following command (adapt it to your case, giving the full path to the .mp3 file first - myfile.mp3 - and then the full path to the TOC file to be created - myfile.toc -):

mpeg3toc -v myfile.mp3 myfile.toc


Did you solve your problem with .wav or .toc?


Ciao

HI Raffaella, I converted my files to Wav and all went well. I will save your post so that I will have it to create a TOC file next time. I thought I had posted that I was up and running. I have shown a young lady that lives next door and is the librairain at the college down the street how to use Cinelerra and she is doing pretty well. She used single track edditing and after bending bands around to get camera moves and such. She had a bunch of jumpy transitions and moves. I showed her 2 track editing where there is room between the clips to have nice smooth transition in the pictures. She said she had not seen that in help files. If some mention of that is not there the addition of that info might help to relieve some frustration for a beginner.. Good to hear from you and Thanks for the Help Doug You know you are my hero:-)
