Hi--in the past I've grabbed and saved a few frames at a time, but haven't been exact about single-framing both the audio and video.

Does anyone have a suggestion for the best tools for isolating a single video frame and it's synched audio 'frame', and saving them, synched, as a single synched a/v 'frame' in a new video file. 

My present attempt is to use jit.movie~ and frame_true to line up a single audio and video frame, but playing that single a/v frame back and saving it (and not more than one frame) into another video file. 

Ideally, jit.vcr~ would be addressable to allow playing a single frame at a time, but I don't see that functionality.

So... anyone do this before, or suggest an architecture for doing this?

Here is my VERY SIMPLE patch to record one frame at a time.

The steps I'm following in the test are given as text in the patch.

Any ideas on how to keep the synch but get the playback up to 60fps? Or why it is creating a captured video with such a low frame rate? Is it the audio capture function itself?

I believe it should play back at 60fps.

So, looking at this simple patch, I have these two questions: 1. Will jit.vcr always capture a minimum of one second of audio? 2. If yes, should I use Apple Compressor to change the output video file to 60 fps? The problem is capturing JUST 1/60 of a second of audio along with the 1/60 of a second video frame. This is giving me about a second of audio with a single frame of video.
