First off, forgive me if I explain something that does not make entire sense, I am trying to figure this out and have come to my ends with it.
I screen capture using Open Broadcast Software at 60 frames per second and a bitrate at 70mb per second in x264 format. That is the first piece of footage.
Then I have a AVI of a After Effects Title Opener at 4k resolution.
I bring both into Premier Pro putting the AVI first and the Open Broadcast Software recording second. The Title Opener and then the content that was recorded on my screen.
Here is where I sorta get stuck...I probably already made errors in what I wrote above so I will just add more... :)
To get the smallest file size that meets YouTube requirement for 4k video which is:
Audio Code: AAC-LC
Video Code: H.264
Progressive scan (no interlacing)
2 consecutive B frames
Closed GOP. GOP of half the frame rate.
Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
Chroma subsampling: 4:2:0
Frame Rate: 60
What should my settings be in Premiere Pro?
Also, if I export from Premiere Pro will Handbrake reduce the file size any further?
Thank you for reading this laborious post...all help is welcome.
