Any ideas how to do that, preferably in a GUI program? I’m not good at CLI or scripts.
CONTEXT
I uploaded a video in Matroska mkv format (~1gb) to Internet Archive. IA added its own converted mp4 of much lower video quality (~500mb) & that’s the only video it will stream. The mkv only available by downloading.
As I’d prefer streaming availability, I used Handbrake (on Linux) to convert the mkv to mp4 myself, hoping to make a better quality mp4 that IA would stream.
Seems successful, plays fine locally, much better quality than IA’s mp4, & smaller file size (~800mb) than original mkv.
But I can’t upload it to IA as I get an error
There is a network problem
400 Bad Data
BadContent
Uploaded content is unacceptable.
Resource>video file has improper extension, try one of these: .mpv .mkv
You can do it with ffmpeg (CLI) and I can give you the incantation for that if you want, but the IA’s transcoding pipeline should really do it automatically and I’m surprised if it doesn’t do it already. I wonder if it’s supposed to and something is going wrong. I assume you used .mkv extension and still got that error. So that sounds like a bug. Otherwise, try renaming the file and re-uploading.
If it’s a bug, you could try contacting the IA and asking what’s up. They do read the emails they get, though obviously a software fix is likely to take a while if they pursue it. https://archive.org/about/contact
