Webm upload problems

I’m getting very annoyed with derpi’s method of uploading videos here. I’ve tried mov, avi, mp4, mpeg, everything in between and it still won’t work! I need a little help here please!

webm is the only video format supported.
 
Here is a simple and quick online converter that also handles twitter posts by their URL.

It seems to work fine with links and the like. But whenever I try to convert things from my photo library and try to post it here, it has a bunch of errors. I don’t know why.

@Calypso The Zebra Hybrid  
Not sure I can help you; I’ve only used it for converting things hosted elsewhere before uploading, and never had any issues uploading the resulting webm file from my PC to the site =/

@The Smiling Pony  
Nevermind that, I figured out an alternative. Disregard that second message.

@The Smiling Pony
I’m sorry sir. I’ve converted my video to webm, but it didn’t work. Any suggestion sir?

@Doerian Roentoeh
Which part didn’t work? Is the webm still under the site’s 100mb upload limit?

@The Smiling Pony
Ok. I’ve figured out it. Thank you :D

Try Handbrake.

I used CloudConvert
