Once you're done, it should look very similar to how it does in the preview window, instead of the mess it was before. The final video will live at combined.webm. I've found this ffmpeg command works well: ffmpeg -i original.webm -i mask.webm -filter_complex "alphamerge" combined.webm Now we need to merge the two videos into a single video with proper alpha transparency.
FFMPEG backend with MP4 container natively uses other values as fourcc. Render the animation and call it original.webm. Now, we will navigate to EditThe Decimate operation in Blender allows you to. Then in World Properties → Surface, set Color to black (#000000). Make sure Render Properties → Film → Transparent is disabled. But instead of having a transparent background, we'll make it black. Now we need to render the animation normally. Render the animation and name it mask.webm. To achieve this, go to the compositor and set up your nodes like this:Ī rendered frame should look something like this:
The bloom appeared to be missing, and the intense emission was not as emissive. So I rendered it out with WebM/VP9 but it didn't look anything like the preview window. Since WebM is a kick-ass video format, it supports an alpha layer when you encode with VP9. This addon highly smooth the process of creating the video file from your freshly exported images.Recently I needed to render an animation in Blender that required the background to be transparent, since this was going on a website with elements in the background. Where you can restart at last image with sequence rendering
The reason is simple, if the direct render of a video crash, you lose everything. To export a video file, it's better to render an image sequence, then generate a video. Multi exports setting override the 'dithering' and 'movement over static background' to create a batch of 16 gifs with every combination of parameters, that way user can just choose best looking one.
Width setting allow to set a new size for generated gif. Choose a folder / sequence start file / video to convert to gif. Make Gif pop up a window to chose parameters and create a very optimized gif from your image sequence. Third Bonus method : Direct Encode - Create an optimized gif using ffmpeg > note: If you have sound in scene, using direct ffmpeg encode might not sync the sound correctly> it's recommended to use the sequencer option
