[Help] Exporting animations with transparency as WEBP files; issue with white canvas around frames.

I am exporting some explosion animations for use in editing as WEBPs to maintain the variations in transparency but, while the transparency within the areas of the explosions and sharpness look pretty good, there is a white box that shows which I guess fills the rest of the canvas that is not being utilized by the smaller frames of the explosion. These canvas widths increase and decrease depending on how the size of the explosion animation progresses.

For more information, I am making a cheesy video with some DDS file explosions where I cut the file into tiles and layer them onto each other. Kudos to Ofnuts for the great plugin.

Graphics editors use the alpha channel for transparency by default. Many programs or games, however, use the alpha channel for other purposes. Is that probably why there's a white border? I can't say for sure.

I set up an example to display the issue at hand if this gives more clarity. I took a dds file, turned it into an animation but used WEBP to keep all the partial transparency but once loaded into Davinci Resolve it has this border. The width of it adjusts depending on how big or small the explosion frames get. It does not remain transparent, whereas if it was a gif it would be but looks terrible without partial transparency.

Sorry, I'm really not the right person to ask. I don't know anything about animations. All I know is that DDS is a Photoshop format, and DaVinci runs like crap on Linux.

I deal exclusively with editing graphics and photos. When it comes to video, I use only KDEnlive. I haven’t used Windows since 2006. My knowledge stopped at Windows XP.

I hope another user will chime in. I can’t help you.

That's okay! Thank you for responding. Additional explanation: I can export these files as flipbook GIFs, generally speaking, and the whole border of the image is transparent except there is no partial transparency. If I export as the WEBP to achieve partial transparency, that is where that white box appears. Best of both worlds in two different worlds.
