Roger's very hard on the venerable AVI format.
Not at all, just trying to be helpful/practical.
It is constantly used as an editing format and encoding source.
Agreed.
WMV is not handy for either.
Agreed.
There are many useful codecs available within AVI. We capture to YUY2
and use HuffYUV before moving files around. We also use the WM9 codec
within AVI to FTP source files to other encoders.
My understanding was this was for file delivery, not editing, but maybe
I read too much into it. AVI is a reasonable editing format, and I
didn't mean to imply otherwise; it's simple, well supported, and
despite many out of spec uses (VBR media, >2GB files, etc) it's somehow
implemented fairly well in many apps.
The answer to the question has already been given. QuickTime will
only read and export RGB24 AVI, resulting in huge files. VirtualDub,
on a PC, will export those files using any available AVI codec.
At any rate, MPEG-1 seems like the best bet for this application.
Agreed; since the specs weren't posted when the question was asked, it
was curious to me that the OP was asking for WM encoding in an AVI -
not impossible, but hardly common. Once the OP posted the requirements
it was clear why that worked and why it was used instead of WMV.
