Stills from Vid FMG Walk Moonlight - Veronique (NSFW) (Patreon)

You might recognize some growth over time ;-)

Some background:
Stills are usually captured before the video is made. The video is made out of the stills (24 per second), where they loose quality due to compression.
Means, if you capture the stills by yourself out of the video, you'll have a quality loss.
