Any docs on when Builder.io chooses to compress video assets

Is there any info on how / when Builder.io compresses videos?

We have one MP4 video at ~9.6 MB that was uploaded fine. We wanted to swap that video out with a new MP4 video which is also ~9.6 MB. It seems to have identical specs—30 FPS, H.264 (Main profile), ~7,000 kbps, ~2880 x 1080.

If I upload it and then immediately download it from builder. The asset appears unchanged. But, a few moments later after a refresh, the same asset is suddenly now 700 KB in size (less than 1/10 of the previous size), it’s now at 720p, and it looks like crap.

Is there any info on at what point Builder starts compressing videos? I didn’t see any options in Builder to turn it off. I’m aware of the optimized=true URL param, but it has no effect on videos which seem to have their asset permanently altered after upload.
