aborted save

If I try to save an edited tv program, the save aborts. This can happen anywhere in a video. After a QSF the save works. Saving an edited film works OK.

If it works after a QSF then that means the original file is corrupt and that's causing the failure. If this is common then you'll have to get into the habit of QSFing all your files before editing. The batch manager can be useful for this if you have a lot of files that need fixing.

Thanks for your reply. I know a forced recode will work but confused as to why films are OK. It seems the abort occurs at the start of an edit which doesn't happen with a film. Also explains why converting mp4 to another format and then editing that still has the error - it's the edit point causing the problem.

You shouldn't have to force recode. QSF just remuxes the files and filters out corrupted frames.

Now if QSF is not working then it could be a problem with the specific edit point. In some cases, depending on the exact encoding of the file, the smart editor can run into problems. Especially at the start/end of a file where the encoded stream is truncated suddenly. If possible it's always best to put your cut point on IDR frames. (or just I frames for MPEG-2) You can display the individual frame type either on the thumbnails via thumbnail parameters or on the video window using display on screen info.

Thanks for the explanation. Using the IDR frames cured the problem. It may be my imagination but the save seemed much quicker.
