[QUOTE="ziphnor, post: 75840, member: 14215"] A small victory. I took tourettes advice and tried to negotiate a completely new buffer size with the VMR9. It took some serious refactoring because it was no longer enough to simply inherit from the CTransformFilter base class(because it the base class has some friend access which derived classes dont get). Anyway i managed to dynamically alter the buffer size to 1920x1080(just to try something). This means i can almost certainly get away with reducing the buffer size and copying the relevant parts as tourettes suggested. It also seems its pretty fast, i renegotiated every frame(only for testing, dont worry :) which maybe dropped every other video frame, so a renegotiation once per second to minute should be entirely invisible to the user. If this works out the only code that will need to be added to MP is: 1. Options in Configuration 2. Insertion into relevant filter graphs if enabled 3. Access from MP to the filter to set options and turn on/off. If i have time in the weekend i will try to get the cropping really working, and then go back to finishing the bounds stabilizer. jawbroken: Btw, without the sanity checks mentioned earlier the start of Swordfish(flashing logos etc) is a good example of why 25 frames moving average is not enough :) [/QUOTE]
