Hey list,

I need to get a raw .AVI file encoded in Cleaner 6.01 on a G4 running
Panther.
The file is 3.4 GB .
After copying it to the desktop I tried to open it in QT 6.4 Pro but it
doesn't seem to work.
I guess it's the 2 GB limit that does it because opening a small portion
that I cut of the original file works great.
QT Pro on the PC doesn't seem to have this problem.


I thought however that the 2 GB limit was addressed and solved earlier.
Can anyone shed some light ..?

There are many 2GB limits... the ones that have been corrected were issues with the operating system and filesystems in general. What you're finding with AVI and Quicktime is that Quicktime (at least on the Mac, I thought also on Windows) doesn't support files larger than 2GB in AVI format, as the original AVI format was limited to 2GB (there have since been improvements to AVI to allow much larger files, but AVI support is already fairly limited in QT since there are so few supported codecs - as proven by your use of raw/uncompressed!).


It's not clear if you encoded the AVI in Cleaner on a G4 - is that true? If so, why not just encode to an interim Quicktime file instead, since you seem to want Quicktime anyway?

Otherwise, if opening 3.4GB AVIs works in QT on Windows, why not open it there, do a Save As and save out a .mov (doing a Save As won't sacrifice any data/quality to any recompression)...

So are you both creating the AVI and wanting to use it on a Mac? Then why not just use Quicktime from the start? It's much more flexible anyway.
