COMMUNITY POLL: Most Important Video Effects? (Quick Response Please!)



  • @Fred you're certainly right. In my case i only use video capture to inject a signal (it can be poor in latency and resolution) after it works in a closed loop in the gpu with two buffers which are treated with shaders effect (zoom shift contrast rotate, threshold hue etc... ) and mixed together. So for me with a 2 gb GPU, a few seconds of video buffer to slow down at some times, it runs really smooth on 4K with 5% CPU usage on my laptop.



  • @ioio this kind of buffer is pretty interesting though, usually it is coded into things like a feedback buffer which could be a cool effect, or multi pass blurs use the same tool to store the image for multi-pass processing.



  • Here is my Cinder based multithreaded buffer implementation, in which the frames are kept in CPU memory and are consumed by the GPU as needed: https://github.com/eighteight/CinderEight/blob/master/PS3EyeSlowMo/src/PS3EyeSlowMoApp.cpp

    This approach will be limited by the size of the RAM (there is no limit check for that though at the moment).
    In addition, the frames could be jpeg–encoded to conserve CPU memory, as shown in this example:
    https://github.com/eighteight/Cinder-VideoStream/blob/master/samples/CinderVideoStreamServer/src/CinderVideoStreamServerApp.cpp#L118
    These examples are using PS3 Eye as input, but can be generalized.

    @videovoce 
    'effect mixer', Yes.. thats a great thought



  • Yes, effect mixer, please!



  • difference

    motionblur
    timeblur
    zoomer
    effectmixer


  • Scaler!!!

    effectmixer
    zoomer
    chopper
    autofade
    In FFGLGradient I would like to be able to set Brightness and Saturation for each color. Also, to have circular, square or reflected gradient would also be nice. 


  • Dear All,

    Thank you for all the suggestions. The programmer is actively working on these now, and I'm going to prioritize the list in response to what you've said above. You can look forward to more news on this by the end of August.
    Best Wishes,
    Mark

    Bravo Mark! Looking forward for the new effects!
