  1. I'm not trying to make a high-def video (these DVDs need to be given as gifts to many people who don't have BluRay players) but I do want to make DVDs with decent visual quality. It must be possible to make a DVD video that doesn't appear blocky - not necessarily high def, mind you, but still with decent resolution. I have plenty of non-BluRay DVDs that don't look blocky, so surely it's not just a problem of the standard definition format necessitating horrible video quality. I did try using the Compressor "SD MPEG2" settings to make a file, but once again, it ended up reducing the quality of the video in a way that was also apparent when I played the DVD. When I reference reduced quality, I mean that the smaller-middle text in the video becomes so blocky/low res as to be almost unreadable. I had read on the internet that it is possible to generate an MPEG2 that burns onto a DVD with multiplexing (i.e. without being re-encoded) but I just cannot figure out what combination of Compressor settings will allow me to do that. I can generate a nice 3.1 GB video with the resolution I want using Program Stream or Elementary Stream settings on Compressor. I don't think those are HD formats, but they still invite ruinous re-encoding when I try to burn them. Has anyone used this method before successfully?
  2. Thank you for the suggestion. Unfortunately, I'm still having the same problem with decreased video quality. Here's what I did: I went back to iMovie, added in a silent track (generated in Audacity), re-exported that as a high-quality movie, re-compressed that into a high-quality MPEG 2, and then gave the file to Toast to burn. Sadly, Toast went right to the encoding step, and in the process the nice MPEG2 was burned as a blocky, unattractive video. I tried playing the lower-quality video on the burned DVD on a DVD player with a standard size television, but the blockiness/lossyness in the video was still evident Is there something else I could try?
  3. 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. My computer: 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.
