hi, am trying to just grab the frames from TOP world when there are changes - these frames are to pulse through Feedback, and i only want those with new information,
nb - Im trying pulse to opacity and similar things, but I wonder how to just grab ceratain frames but Im pretty sure there is a cleaner quicker way !!
I think what you are after is the ‘Movie File Out’ TOP - add that one in, right-click it and choose ‘Operator Snippets’. Have a look at the ‘one image file per click’ snippet as this might be what you are after, and you could simply replace the button in that snippet with a setup of your own.
Thanks, I did snoop around this idea, will have another look.
It’s all about getting everything super tight when you are after exactly first frame of something…!!
Perhaps you could use the ‘Cache’ TOP - there is an option to ‘Replace Single’ via a pulse - you could pulse this as the frame is generated.
Or for even more granularity, you could look at the ‘Execute’ DAT - there is a function you can call on ‘Frame Start’ or ‘Frame End’, so you could use this to capture at the beginning and end of a frame. Just be careful, however, as this function will run every single frame, so be sure to filter out when it would execute.
