"In the 1080 24p mode, the images are scanned at the full 1080 lines, and 2:3 pull down is added and recorded to the 60i HDV tape."
Are you editing in the same type of sequence (30i, also mistakenly called 60i) and exporting to same?
No, I'm editing in an HDV 1080p24 sequence. I wanted to edit and export as 23.976p, so that's why I chose that preset.
According to the preset's description, it is "For editing with IEEE1394 (FireWire/i.LINK) HDV equipment. 16:9 progressive-scan 1080p HD video at 23.976 frames per second. 48kHz audio."
As a test, throw some media into a normal 30i sequence and export as same. Does it still have the artifacts you were noticing?
Already gave that a shot. Same result as the HDV 24p sequence.
