I don't know what's going on! My MPEG4 video looks ugly/pixelated/blocky when I try to burn it with Toast due to the encoding step. I used Compressor to produce an MPEG2 video of satisfactory quality, and I want to preserve that quality when burning it onto a DVD. I don't want there to be any music accompanying this video, and the video itself has no audio track. However, Toast crashes every time it gets to the multiplexing step.
MacBook Pro running OS 10.8.4
Optical Drive: Matshita DVD-R UJ-8A8
Burning onto a 4.7 GB single layer DVD
The file I want to burn:
Kind: MPEG-2 video
Size: 3.17 GB
In Compressor, burned with size=[1080x1920], fps=29.97, 10 Mbps (14.8 Mbps max)
The burn DVD settings I'm using:
Video: [X] DVD-Video
[X] Auto-play disc on insert
[X] Custom settings: MPEG-2, 9.0 Mbps (9.0 Mbps max), Reencode never
When the prompt box about audio comes up ("This track has no audio! Would you like to select a track..."), I select No. Then, when I try to burn the DVD, the first step (multiplexing) crashes Toast, and my computer acts as if I only just popped the blank DVD in (prompt box reading "What would you like to do with this DVD? [ignore] [show In Finder] etc...").
If I do choose a .aiff file (40 minutes of silence, generated in Audacity) to associate with the video I want to burn, the DVD will burn normally...however, instead of multiplexing, the first step will be encoding, and this ruins the quality of the video I'm trying to burn.
TL;DR I want to burn a silent MPEG2 file to a DVD. If I associate it an .aiff audio track (Video: MPEG-2, Audio: 16-bit, Mono, 44100 Hz), the video is encoded, and the resulting DVD looks bad. If I do not associate an audio stream (Video: MPEG-2, Audio: None), the first step is multiplexing, but the whole of Toast crashes before it can get even 1% into the multiplexing step.
