I’m trying to build a patch for video scratching using MIDI controller no. 12 and the scratch performance is erratic, meaning, I’m only capable of working very slowly with the MIDI controller. High scratch speeds cause very bad behavior.
I’m using MJPEG codecs with keyframe every frame for best scratching performance.
I’ve developed video scratch solutions with other languages before, so I’ve been trying similar technics, but maybe they aren’t suitable for vvvv. For example, you may see my Gephex-based MIDI scratch system (VJ Tailor is my VJing alias while VirtualFlavius is used for research)
Attached is the barebones patch, I’d appreciate it if you could please check with your own videos and provide your ideas on how to make it behave better.
