disagree
it's hard to estimate (esp. if you even compress index, and/or use
scene-chanege detection) and it wastes space (because you have to allocate
more space than estimated to be sure it will fit)

anyway since this format is raw seekable, the index has no much use anyway.
it's far enough to place it at the end.
