It’s not web based but MKVToolNix GUI is pretty user friendly. I haven’t dug into it too deeply so I don’t know if it offers any automation tools to batch change files etc.

FAN OF ALL CAPS TITLES AND VOTE BEGGING I AM NOT

I whipped up a basic page with PHP and just used XAMPP when I was on Windows. I recently switched my daily driver pc to linux and haven’t updated it yet. I only used it to save MP3s, videos at yt-dlp default “best available” settings, and a custom option that lists available video/audio formats where I can specify the ID to grab of each. No validation or sanity checking etc, just some switch statements and basic form functions.

This could have been a fun mashup but this execution just feels kinda wrong/gross overall to me.

• Why are so many main characters not included (Hermes, Zoidberg, Nibbler etc.)? At least Bender is present as the flaming mass we all fondly remember from the film…
• Was it really necessary to include perky nipples and a camel-toe on Amy?
• The staff Professor Rhod is holding has what resembles a golden swastika in the only significant change from how it appears in the movie. And though the Professor is occasionally shown without teeth in the show is there a reason he doesn’t have any here?
• Why does that train have eyes?
• Just a bizarre composition in general. Why include so much of the stone and vents around Amy, then make the openings between the slats just reveal the background image? If Leela was shifted over slightly left her fading tendrils and feet could have been cleanly hidden behind the Professor.
