I believe i may have rendered all the frames incorrectly with the wrong setting. Basically i am trying to create a GIF of my my video with a transparent background. After i rendered the animation with the "transparent" box ticked in render properties, all the frames have just a black background. When i import these images into the GIF converter, it doesnt register the black background as alpha.

I believe i had to set the output as RGBA when i rendered the animation. Is there a way i can reprocess these images quickly without having to render the entire animation again?

Any help is much appreciated.

Rendered frame with black background not alpha

  • $\begingroup$ I think there is no solution that is any easier or quicker than just re-rendering. It looks like a straight forward scene. $\endgroup$ – d8sconz Dec 30 '17 at 0:56
