Hi
The question is: has your quicktime file the 'pasp' atom but it contains wrong
values OR your file doesn't has any aspect ratio atoms ('pasp' or 'tapt') at
all?
There is small OSX application called Dumpster to inspect and edit quicktime
file's structure. But Dumpster can't add or remove atoms- you can only edit
some existing one. So if you file contains aspect ratio atoms you can simply
edit them.
There is no a simple way to manipulate quicktime files via Python but.... In
32-bit OSX Python builds there are Carbon modules which- among others- contains
python bindings to Quicktime framework. With them you can manipulate quicktime
files almost the same way like with sdk, but of course you need to know the
Quicktime framework a little bit.

I opened in Quicktime Pro, but there is no mention of pixel aspect ratio
anywhere.
I seem to remember that on this list someone took care of the gamma problem in
H264 files by using Python code to remove an atom. Maybe something similar can
be done for pixel aspect ratio?

Have you tried to open the file in QuickTime Pro and check if there is some
"atom" that you can change there to change this?

Hi all,
This is really a Quicktime question - but the answer might lie in the wonderful
Python capabilities of Nuke, so it's worth a shot.
I have a Quicktime file that has a wrong pixel aspect ratio. I just want to set
the PAR to something else without having to re-render the file. Any idea if
this is possible?
