Does the “24” refer to audio or video?
If it’s audio, go to the Project Properties – Audio screen to make this switch.
If it’s video, 24 bit is a standard image while 32 bit has an alpha channel.
HTH.
Gary is right. I did this last year with a grad video. I added another folder containing all the photos used in the project (at higher than video resolution for printing purposes). Once DVDA prepared the video files, I added this extra folder and used RecordNow to burn it as a data disc. No returns at all.
