Your video looks progressive, and it appears that you're using it in an interlaced sequence in Premiere. That'll happen if you do that. Either interlace your source from AE, or use a progressive sequence in Premiere.
All of the shots have already been rendered in AE.
Do I select "Sequence Settings" in Premiere to change the sequence to progressive?
You need to create a new sequence that matches your source from AE.
I don't have a lot of Premiere experience, but when I want to create an NTSC Widescreen sequence, these are the video specs:
For editing with IEEE1394 (FireWire/i.LINK) DV equipment.
Widescreen NTSC video (16:9 interlaced).
48kHz (16 bit) audio.
Drop-Frame Timecode numbering.
Frame size: 720h 480v (1.2121)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC Widescreen 16:9 (1.2121)
Fields: Lower Field First
It automatically makes the sequence interlaced. How do I make it progressive?
(Also, can I copy shots already edited into the interlaced sequence, and paste them into a new progressive sequence?)
