I'm trying to mplex a 1.73GB mpv file and a 47.7MB mp2 file using sizzle 0.02r or ffmpegX v0.06f. However it fails with the output below (from sizzle). Both audio and video files are created via Mediapipe from a 30 mins, 5.52GB, Quicktime Movie file that was exported from imovie2.

I've had a search on the forums at dvdrhelp.com, 3ivx.com and the mailing lists for mjpeg at sourceforge.net, not found the answer yet. Many people seem to have problems with file sizes over 2GB, but mine isn't, so I'm confused.

Any idea what it means by too many frame drops? Is it something to do with bit-rate? file size? Too slow a processor? I have successfully mplex-ed smaller test files (30 secs length, ~ 5MB mpv file size) using Sizzle at the same bit rate.

FFMpeg fails the same as sizzle (since they both use mjpeg tools, but does manage to half work, in that it creates a VIDEO_TS folder after exiting mplex of the incomplete mplex-ed file:

Anyway, after a bit of playing about I've gone straight to the mplex command line tool in the Sizzle package (OS X is great for this), so I can try some of the options suggested here http://roguelife.org/~fujita/MJPEG/mplex.html

Currently playing about with the video buffer size after a suggestion from the author of Sizzle,

I'll feed back if I have any success

Well as suggested by a few people (on the mjpeg user list - http://mjpeg.sourceforge.net/) the problem I had was with the overall bitrate I was trying to mplex. I should have realised this, but the 9.8 Mbit/sec maximum (that is mentioned on the sizzle documentation pages) is a mplexed maximum, not the separate video stream. www.dvdrhelp.com lists dvd as having a video bitrate of 3000-8000 kbps and audio as 128-384kbps, which I'm guessing adds up to the 9800 kbps (Or maybe not).

So I re-encoded my video at 8000 kbps (took a day or so )and left my audio at 256 kbps. This worked. No problems at all with mplex or anything else.

Burnt a DVD and tested it on my computer, worked fine, apart from towards the end it would start to skip a bit. Perhaps because it's still on the high side of bitrate? (If I do a DVD again, I think I'll go a bit lower than 8000 kbps to be on the safe side) Checked on my friends dvd player, worked fine, but didn't get a chance to check the end. However, all was to no avail when it didn't work on my girlfriends dvd player though so now trying SVCD, and if that doesn't work, VCD.
