还有传授一下经验
我明明把声音分离出来了

1、压mp4和压其它东西没什么差别。区别就在用了mp4封装。就和mkv封装差不多的。

mp4、mkv、avi都是封装格式
MPEG-4是标准的名称……
三楼混淆概念了

如果是DVDRIP出现不同步，检查一下你混合音频的时候有没有设置Delay值

你说微软的avi和dvix封装的avi一样吗？
你说封装的mp4是标准的mpeg-4吗？:confused:

那你说的mp4怎么封装？
视频用dvix音频用aac?
这样psp能认吗？
不好意思 新手问题多

doom9上的MP4 FAQ, 应该能解决lz的一些疑问 lol

What is MP4? I have heard it is a "container format"? What's that?
A container format allows you to combine different multimedia streams (most of the time audio and video) into one single file.
Multimedia containers are for example the well known AVI (.avi), MPEG (.mpg, .mpeg), Matroska (.mkv, .mka), OGM (.ogm), Quicktime (.mov) or Realmedia (.rm, .rmvb)

MP4 is the global file extension for the official container format defined in the MPEG-4 standard (ISO 14496-14)
MP4 is streamable and supports all kinds of multimedia content (multiple audio-, video-, subtitlestreams, pictures, variable-framerates, -bitrates, -samplerates...) and advanced content (officially called "Rich Media" or "BIFS") like 2D and 3D animated graphics, user interactivity, DVD-like menus... - next to nothing handled by the often used AVI

How can i create spec compliant MP4 files?
easy answer: have a look at Doom9's MP4 Guide or Nero Recode2 Guide

detailed answer:
1) To create MP4 files you should preferably use audio/video formats covered by the MPEG-4 Standard:
- MP4 video formats: MPEG-4 SP/ASP: XviD, DivX5, 3ivx, ffmpeg/ffdshow, NeroDigital ASP... and MPEG-4 AVC/H.264: x264, NeroDigital AVC, Apple... and MPEG-2, MPEG-1 (not DivX3/MS Mpeg-4, WM9, RV9 or VP6) - doom9's quality comparisons: 1 2
- MP4 audio formats: Advanced Audio Coding (AAC FAQ): Quicktime/iTunes, Nero, Psytel, FAAC (binary)... (rjamorim's quality comparisons: 1 2) and MP3, MP2, MP1, CELP (speech), TwinVQ (very low bitrates), SAOL (midi), ALS (lossless)
- MP4 subtitle/text format: MPEG-4 Timed Text (see question 7)
- MP4 picture formats: JPEG, PNG
