Is there an effect to reduce the frame rate / posterize time (as after effects calls it) - with out changing the length of the clip / for live sources?
Perhaps I missed it, but I only find effects to blur btwn frames. The best work around (kinda) is to use a step sequencer to turn on/off a freeze frame effect. Which isn’t exactly great and has limited speed control options at best.
With video files I know you can just play them slower. Basically trying to replicate a video feedback set up I had with a hardware mixer and a camera - reducing the fps on the feedback input to keep it blinking out of control.
I think you might have more control / options if you use two layers and toggle between the original (overlay) + copy (Add). That way you could add opacity and timing to the layers and FX. Note: the gif output is not a fair representation of the freeze/blur the original video is much more fluid.
thanks for the suggestion. I am not following what you are suggesting. The first step seems to be what I am already doing - using a controller to turn on/off a freeze frame.
I am not looking to blur btwn frames. Just reduce the frame rate. added gif ref of what I am looking to do.
I initially thought this would be something I could figure out in quartz composer, but all the google results are discussions about how qc fps is too low.
Seems like in isf or vou - the steps would be simple(?) - video source, math toggling between 1/0 to pause unpause video frame, and a slider to control speed of oscillator.
but isf code is beyond what I can cobble together and vou is more $ than I want to spend given my hack solution I have already.
Ah, now I get what you mean. Just stop the play head and add a data source to the jump forward button (say Clock 1/Every Beat). Set the dropdown to Frames and adjust the timing for your application.
I think you will have to do that in-camera / hardware or via a third party framework and then Syphon in to VDMX. Sounds like you are looking for a slow shutter cinematic FX? You could go down the old school route and use a spinning shutter in front of the camera lens with an Arduino to adjust the speed. Way more authentic if that’s the look you are after.
The controls are super weird. Not sure why there is 3 buffer controls and 4th global control. I think I tried it before but forgot because of the name of the effects.
