yellow powder tests
Added 2024-04-06 11:32:03 +0000 UTCJust sharing some early footage of some yellow powder explosions I filmed last week. Small scale stuff, confirming that the mix does explode like I expect it to! Also trying out some more high-speed footage things, this is ramping my camera up to 15968 fps! I'm not sure how useful that footage is though, because it feels hard to convey how many frames it is, and at a 336x240 resolution- it is a bit jarring to watch. It has also been upscaled to a resolution of 672x480 (using TopazAI) which is about as much as I can upscale it before it starts looking weird and AI-like. But still, jumping between 4k footage and 480p footage is a bit rough?
Anyway, many more explosions to come. Hoping to get the yellow powder explosions very reproducible and reliable, so we can actually start doing some science with it.

I would strongly prefer watching it in 480p (either nearest-neighbor interpolated or with something like bilinear) and knowing that each pixel corresponds to the observation in some straightforward way, than watching it in a higher resolution and not knowing if what I'm watching has any correspondence to reality or is just a hallucination of a statistical model

2024-04-08 05:02:10 +0000 UTCIt really doesn’t look bad, I think slow mo guys have got most used to the idea that super slow mo is lower resolution. Is there an option in the camera to reduce just the vertical resolution but maintain the horizontal? I know that’s something SMG’s do to make it less jarring

2024-04-07 12:58:24 +0000 UTCjist display them as 336x240 in the center of the 4k frame so it feels normal. or release the whole video as a 360p throwback to early youtube videos of extremely poorly thought-out chemistry demos/.
