Format of QT files used in Almara does not support files > 2
GB. IIRC there exists some version of QT format that solve
this, but support for that format is not implemented in Almara.
Regarding AVI the situation is similar - although AVI files
supports large files, this extension of AVI format is not
implemented.
Probably jpegs2mjpeg doesn't handle this very well and
crashes instead of outputting some reasonable error message
- could you please post its output here?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I've looked all over the net for a program that can handle large datasets
but to no avail. Virtually all of them have the 2GB limit. There might be
something that could be done in QuickTime, but one of the benefits of a
program like yours is that it writes directly to files and is very quick-
QuickTime would want an in-memory version before flattening the
movie. We're doing 5hr+ research study sessions, which results in
about 20GB worth of images!
Any chance your program will get an upgrade to a different QT container
format?
Also, we do have a temporary workaround. I've written a java program
that feeds your program a list of images up to 2GB in size (minus a
buffer for header info) and generates temporary movies until we've
processed all 20GB. Afterward, we can use another program called
QTCoffee (specifically catmovie) to concatenate the temp movies. It
works OK, but it could be better! Here's a link: http://www.3am.pair.com/QTCoffee.html
Here's the output of a failed capture session. Could also use a quick
spelling fix: writting -> writing.
