Bug Report OBS seems very confused when it comes to transparency that is not 100%, potential glitch report

[leomozoloa]

hello !

I've been struggling for a while with transparent video, it seems that obs interpret glow type transparency as black no matter what and is incapable of having smooth soft shadows or glow, I've compiled the results so you can see (i love using cineform so this really pains me)
here's a preview of a simple white ball that doesn't move and has a glow on it (no black involved), i'm using the last version of OBS, updated everything windows nvidia etc. My goal is here to make animated transparent videos with shadows and glows, so just going png is not an option.

I don't think a log file is needed since nothing crashed and the videos are imported fine, seems like the devil is in the details, you can easily try this at home, I can give you the cineform file if it helps: here https://drive.google.com/file/d/1QWgWTi3NMPOV16vTgYX0qyZL5WLBLb-l/view?usp=sharing

Hope someone can help ! I'm making a living from cool animated transparent assets

Does anyone wants to at least reproduce the bug at home so I'm not under the impression that no one minds that glitch except me ? xD

You need to use the 'Media Source' in OBS Studio to import videos with alpha (the simplest way).

For stinger type of the transition in OBS Studio recommended format is qtrle, .mov file:

While your sample file is black and white, for real videos - I recommend to you to check the color import in OBS Studio before using this media in your production (RGB, 8-bit per channel, test charts):
