Bad UX due to large unoptimized video size

[janviehweger]

When accessing the Firefly wallet on a low bandwidth network, I was unable to access the migration video. The three-minute short clip is 240MB!!! big, which is definitely way too much. It doesn't seem to be optimized at all. I was able to sample the video down with handbrake to 29mb at 1080p without any loss of quality. 720p would be sufficient also to my opinion.

The video:
