Hi Francis,

Looking at the ImageJ source code for the AVI writer, it does indeed cap the
frame rate at 60 FPS for some reason, though I am not sure why. I have
forwarded your question to the list in case anyone else knows the reason.

Hi Curtis,

I wasn't sure whether to send this to you or the ImageJ mailing list.
It's a report of a presumed bug. Actually, I already tried sending to a
list but it bounced because my email address changed recently, so I am
about to switch my subscription.

This is what I wrote:

A colleague wants to use ImageJ to do some simple .AVI file editing and
is using File/Open... and File/Save As/AVI... to read and write his
movie files. The frame rate of 140fps is recognized when the movies is
read but is not preserved on writing. The AVI Writer module appears to
be truncating the frame rate to a maximum of 60fps even when 140 is
entered in 'Save as AVI...' dialog box. Is there a way round this
limitation?

Cheers,
Francis
