• Increase video bitrate to respect video fps.
• Detect video format based on FRAME_HEIGHT to prevent blackmagic from using a smaller frame.
• Potentially fix audio issues with a larger bitrate.

@fieldsJacksonG I can see you will still have fps issues - for example sometimes we need to use 25/50fps for PAL format. Is there a way to detect the frame rate also?

[fieldsJacksonG]

Took a brief look at this - we may need to manually set the frame rate, either in the compositor or plumb the selection option through to the compositor window in Unity.

if we can have a drop down in compositor window that would be awesome.

Drop down will be in a future commit - I will need to modify additional files to make that happen.
