C/2025 A6 (Lemmon) animation 04.10.2025

For me, it's the opposite. But that's due to the specific device you're viewing it on.

That seems to be the case, apparently!

Indeed. I was working on and uploading it on the computer and didn't notice anything like that. After your comment, I looked at it on my smartphone, and the preview there is so flickery it makes your eyes hurt. It's either a device-specific issue or the algorithms converting mp4 to gif (you can't make a gif in Siril).

The video won't load at all. The preview in the squares loads a little and then freezes.
Probably better to save the sequence from Siril as TIFF and make the video in After Effects.

You can't upload videos here anyway; you'll have to convert it into a GIF animation. Does Ae have a save mode for GIF?

Yes, but you need to select Animated GIF.
