Known Issues

Rendering on chrome doesn't work in multi-threading mode (it seems to fail on mp4s)

Rendering progress bar
"Cancel Render" button
Disable/enable filters without removing them
Deal with duplicate parameters in filters (sometimes filters have a long and short option)
Add more help/documentation in the filters (there is more on FFmpeg's site that I could incorporate)
Add input options like seek and trim
Somehow figure out how to deal with complex filtergraphs
Add more sample inputs (at least need an image and an audio file)
Put filter options in a separate panel
Add filters that generate content
Handle audio and image output.
Allow command to be editable
Use commas to separate filters when possible
Include some default fonts so text works.
Allow gif as output
Add more tests!
MAYBE allow users to upload their own videos
MAYBE make each part of the output command clickable, to highlight the corresponding nodes
MAYBE add previews in the filter list itself
