i'm currently doing a project dealing only with greyscale video which is captured from a live input, converted to greyscale and then buffered into a 1-plane-matrixset and am wondering wether from there it makes sense to go for an opengl-architecture (which is hardware accelerated but deals with 4 planes) or whether i should rather stick to my 1 plane-matrix using standard jitter. i do need to apply some effects:
- text overlays
- simple graphic overlays (sort of a moving onscreen slider and images with alpha)
- some keying with fixed alphamattes. the matte itself will be a still image but might need soft edges, all inputs will be greyscale vids.
- some normal fading from one greyscale vid to another.
- very basic image analysis (bang when live input gets dark)
the final output will be in greyscale too so basically i could go all the way with my 1-plane matrix. on the other hand i keep recording while rapidly shuttling around in the video and there's happening some other stuff too so i guess i will need some cpu-power.
opengl or not? that's the question...
any advice is highly appreciated!
