Aside from the jitter option I wouldn't classify this as glitch art.

It (accurately) states "no upload" so the subsequent button probably shouldn't say "Upload Video"

What might be cool is converting each frame to JPEG and then randomly corrupting bits in the SOS section before displaying each frame. Then you'd get proper glitches like what you might see off a damaged memory card.

It leaves my camera on even after I close the tab.
