The patch I'm working on needs to record sections of live video

to disk - then if required - record over these recordings.

I am writing to disk using "write peter1.jpeg 30. jpeg max 600"

When I go a press "write peter1.jpeg 30. jpeg max 600" again, nothing happens.

I am forced to rename the file make a new recording... why?

Secondly - where does max auto record these files to?

You could make several message boxes that indicate different file names and just use a trigger b b b or something every time..unless you're doing a lot of debugging..but thats the way I've done this in the past

I'd just search for where it's storing your files..it's prob ably the desktop..you can always specify what filepath it uses in the messagebox with like /Macintosh HD/user/desktop/....

write orig 15. jpeg normal 600
write fadeone 15. jpeg normal 600
write fadetwo 15. jpeg normal 600

Thanks for the tips - I've managed a similar solution - where by I created some dumby videos (of just solid colours) to be played whilst the live feed is being recorded.

The live feed covers up these dumby videos so they are never seen, whilst the file beeing recorded too is always free.

My problem now is that the playback of the recorded videos is too fast.

Even setting the rate to '1' appears too fast - where as a setting of '0.3' for the rate seems more appropriate to the original speed.

I'm currently writing the recording as a .jpeg.....

Why is this? Any clues?

check your fps when recording..I bet you're not recording at 30fps its probably more like 12 or something which means it is playing back 3 times as fast. A way to change that is to send jit.qt.record a message of 'realtime 1' (i think its 1..im not in front of it now) ..check it with the clue box and see what real time means to jit.qt.record

this will make recordings play back in the same space they were recorded in. If realtime is off then it just records when it receives a new frame..this if it gets 12 fps and is recording at 30fps..it's going to play back about 3 times the speed..12fps will look jerky but it should look better at least if you set it to record in real time as opposed to frame by frame

So yeah, I set the arguments for realtime to 1 and playback was correct speed.

Now if only jitter could playback smoothly in general instead of this jitter every 2 seconds or so.... :-/
