Specific frame rates for output recording	Can't Post

Any suggestions welcome:
I'm trying to record the output from two stages (obviously having to do one at a time) where the frame rates are entirely constant (ie. 25 frames per second) so that both recordings can be syncronised at edit. Isadora seems to "do the best it can" in terms of frame rate, rather than sticking to a specific one, even with a very slow render speed. Is there any way around this?

Many thanks for your thoughts,
Gareth Risdale.

if you adjust your output speed in the "record stage settings" down to say 25% i think you will find it will output a full fps

Changing the "Render Speed" in the "Record Stage Settings" is absolutely correct. But there is a big caveat if you have QuickTime 7.2. or later. Because of the ongoing and not yet fixed bug in QT 7.2 and 7.3, the non-real time rendering feature is disabled if you are using Isadora 1.2.8 or later.

However, you can restore this feature by going to the Preferences, clicking the video tab, and un-checking the "Enable QT7.2 Workaround" checkbox. After you do this, the audio associated with Movie clips will not play; but you will be able to use the non-real-time rendering feature successfully. Since Isadora does not record the audio when recording the stage, this should not matter.

Once you're done with your rendering, you'll want to re-enable the workaround.

Best,
Mark
