feature request for jit.qt.record


I have a small (hopefully) feature request for jit.qt.record – to
have it output some sort of message out of it’s right outlet when the
user has selected a file via the file dialog, or if they haven’t.
Something like “writing FILENAME.mov 1″ if the user successfully
chose a filename via the OS dialog box or “writing 0″ if they
canceled it. Is that even possible? (some creeping suspicion in me
thinks that it isn’t)

This comes up a lot, and I noticed that Randy Jones wrote js to get
around it, but it’s a little convoluted and would be so much more
useful and simple if it was all in the jit.qt.record itself.

Plus, it was my birthday 2 weeks ago… c’mon Jeremy, can I please
have this as a belated present? Please please please? :)

This is possible. I’ll add it to the list of things to ponder.

Great!! Thanks, Jeremy.

Until this feature makes it into jitter, I found another way to
accomplish this (e.g. to get a bang/event when the file is actually
being written to disk, or if it was canceled). It uses the “gettime”
message, which only seems to report the currently recorded frame #
when a file is being written, or it reports a bang otherwise.

my last solution doesn’t seem to work in some cases – if the file
already exists, and you try to write over it, gettime reports nothing
instead of 0.

Bug report:

“gettime” msg doesn’t properly report the correct number of frames
recorded to disk in some situations.

Expected behavior:

A “write” message to jit.qt.record followed by a “gettime” message
should report “time 0″ (the start of the file, no time recorded).

Problematic behaviour:

This works properly UNLESS the file already exists and would be

Steps to reproduce:

See patch below – send “write, gettime” message, and see that “time
0″ message is received. Then send “write, gettime” again, selecting
the same file name in the OS file dialog. “time” message will be

I can’t reproduce this on Mac. What OS are you using? You’re missing
a framerate in your write message, btw, so your patch doesn’t
actually work.

sorry, i copied/pasted that patch from another. sloppy of me.

i’m on 10.4.6 with QT 7.1.1.

i tried reproducing it again, and realized that this only happens
when you have finder open and the movie selected and the little
preview open in the finder window (the right-most preview pane of the
finder window). otherwise it works in all the other situations that
i tried. i had a few windows open with previews, and this must have
been the cause of the trouble. this seems like more of a mac/finder
issue than a max one, I’m guessing. but is there anything that can
be done to test for this case?
