Subject: Re: getting AVIs into a file format that will work with IIDC and Keith's stacker?
Couldnt you just use QuickTime Pro to convert the avi to .mov file?
Or is that not loss-less? Ron

Hi Jon;
1) First off, can you open and play the AVI file with the
QuickTime
Player on a Mac or on a PC?
If you can't play it, the there is no codec for it decompress the
video. So you need to get that codec installed on the Mac before
the
vide data can be used by any application.
Under Windows, I believe you can determine what codec it was
created
with by examining the "Properties" of the .avi file.
2) If youy can't find that codec on the Mac (lots of them do not
exist on the Mac such as Huffy YUV, Microsoft MP4 flavors 2 and
3,
various Bayer codecs etc ), then Virtual Dub
http://www.virtualdub.org/
will be able to convert any playable AVI into an RGB24 AVI
format,
which should be a loss less conversion (Youcma's only deliver 8
bit).
You can then copy the enormous files over afterwards.
3) Astro IIDC does import nor manipulate FITS files. It can save
frames as uncompressed FITS files, but it won't do anything with
them.

After being a Win user for so long and only recently acquiring
the Mac
specifically for astro work, I am running into a few problems,
mainly due to
my lack of experience with the Mac. My biggest problem is file
compatibility. I have scores of AVIs that were recorded with a
Toucam and
Win laptop that I would like to reprocess with Keith's stacker
and
IIDC. I
see that Keith's program appears to recognize the AVI, but then
keeps
distorting the files after I try and save them. I have tried
converting
AVIs to FIT and so far, I can't get either program to work with
the
FIT
files. Can someone provide some pointers for the best
conversion
method--
from AVI to any of the Mac program formats- and a method that
will
preserve
the contents of the original AVI (no loss)?
Thanks to all,
Jon
