看到了一个讨论,说原则上AVI是不允许B帧存在的,而我们实际是用了延迟帧这种hack技术来实现的(packed bitstream).但AVC允许比B帧更完全的参考,所以如果仍然走老路的话起码是无法发挥出AVC的威力了.所以:
Basically, what it comes down to is this:
-If you want to use AVC, don't use AVI.
-If you want to use AVI don't use AVC
(unless you use a VFW AVC encoder (e.g. x.264), but certainly not Nero)
呵呵,大家还是做好迎接新一代MKV的准备吧.新的mkv将不再依赖avi了,而可以直接作为一种流来编辑.
