With that little correction in mind, I tried to simply convert each frame to 'RGB' before saving as GIF, and that solved the issue for both cases! (both if I first convert the images to 'RGBA' or paste them unto a transparent PIL image as I mentioned in the beginning) Since the pix...
FFmpegRGBAToYUV An application may generate sequences of "raw" RGB or RGBA images, for example a 3D application that renders an animation. In such cases, it would be useful to create a movie file in some standard format. FFmpeg has the capability to create movie files, but as far as I...

NvMedia2DBlitEx does not support RGB format so we have to convert from rgb to rgba before we use NvMedia2DBlitEx. Is my understanding correct? Yes eri.kasamatsu: Can NvMediaImagePutBits and NvMediaImageGetBits be a bottleneck of the program when we use NvMedia2DBlitEx just to convert RGBA...

We encode these overrides as the RGB vertex color. Left at their defaults of white, these overrides pass all control to the simulation. Bringing down a channel to zero modulates an effect.The red component governs the overall transparency, making the water surface completely transpar...
