This is driving me absolutely mad...
I'm now trying to render a different song from the same night but am getting another glitch, this time during a shot from the 720p footage.
I'm sure this issue has its roots in the media/project/render settings triad.
I start the project by matching the project settings to the 720p footage and when I render out I go for:
MPEG2
NTSC widescreen, 720x480, 29.9p, 16:9
I-frames: 15, B-frames: 2
Profile: main, level: main
Upper field first
Video quality at highest setting
Variable bit rate, two-pass
I've also tried adjusting the project settings to the NTSC template before rendering but I'm still getting glitches. (Full resolution rendering quality set to full and deinterlace method: blend fields).
Is this something to do with using variable bit rate?
Any pointers would be very welcome.
EDIT: Just realized that I'm rendering to an interlaced format - will try again in progressive
FURTHER EDIT: Nope, just rendered to progressive and got a glitch that involved the bottom third of the screen jumping to one side momentarily during a shot from the 720p cam
