Unfortunately Twitter butchers video quality.

I remade both landru79's videos from scratch using original ESA 2048x2048 image sequence (plus I added a bit of motion interpolation):

Edit: in case my server doesn't hold up, here are video mirrors on Streamable:

(seems better quality than Twitter and YouTube)

Dear NASA -

Science is amazing. Don't forget to make it relatable by doing work like this! People love to see great images, so you gotta curate them and highlight the stunning stuff like this!

Rosetta was actually built and launched by ESA, not NASA :) Still, I couldn't agree more with your comment.
Would love to see these without the frame interpolation (which totally chokes on all the particulate matter).
Here I made one for you, using just the original frames:

Extra: I also attempted to denoise somehow (with Gimp's despeckle filter), though it's kinda weird :)

Beautiful!
You're very talented, this is dope. Thanks for taking the time to make this and share it with us!
Credit should go to landru79, he keeps finding interesting things in Rosetta's raw data. I basically just tried to correct for Twitter's terrible video handling by re-tracing his steps :)

Go check landru79's Twitter feed, there are many more interesting comet images and videos (e.g. he combines multiple frames into color images):

BTW here are original ESA images:

Thanks for giving credit where it's due and your own work. I note that landru posted a GIF which is ironically much nicer than the video:

What is that light on the left?
Reflective flare from the sun, perhaps?
Doesn’t look like anything to me.
