Re: Downconvert 720p 23.98 to 29.97 Betacam Problem

Jeremy,

I guess I owe you at least a good cup of coffee! Thanks for explaining why the 59.94 setting works. I didn't realize the footage was already being processed by the computer so the monitors can display it.... makes sense.

Regarding the conversion to interlaced from progressive, I was assuming the every frame would be converted to two interlaced fields of scanned information.... not just the filler interlaced frames included for timing purposes I'm assuming we see during playback in the 23.98 timeline. Since each frame would be interlaced and scanned onto the screen, I thought this might even out some of the jitter associated with faster moving clips? I have a shot I really like where a giant wave crashed in front of a nice sunset, but I'm getting some motion artifacts as the water explodes into the air..... it's driving me a little crazy since the shot is great otherwise. I was hoping that by converting the shot to interlace from progressive I might be able to smooth out the motion a bit. The other factor would be the pull down settings. From what I've read on the message boards, the best setting would be 2:3:2:3. ?

Thanks for your help....... perhaps I should throw in a danish with that cup of coffee?
