Two-Pass encode........

[daniel]

Thanks Mike, still confused.

What I tried to say is we could keep a 8264kbps copy of the rushes (HOME use) for an unplanned later re-edit with reasonable results, when the real target could be done at maybe 5000 and still look OK to us, usually happy with VHS.
While keeping the AVI original would use an unbearable amount of hard disk space, and tapes are both unreliable over time (physical and magnetic wear and tear under HOME storage conditions) and more expensive than a DVD.
With the same reasoning, using VBR and getting a possibly better result would be a precaution if nothing is against it.

When you warn against some authoring apps unhappy with VBR it doesn't have a strong relevance to us users of VS, serious people use programs with a serious price. If I for instance needs someday to re-edit, it would be with the same VS that was used in the first place, so I guess it would be able to process it.

But of course I dutifully memorized the "editing doesn't like VBR" bit.

So would it be reasonable to keep the rushes encoded CBR at 8264, dual pass, for best compressed trade-off, for archive DVD.
And then re-render the "presentation DVD" at 7000(?) VBR single pass.

Or am I completely off-base here?
