need some help w/ decomb for a bizzarre clip
Posted: Tue May 10, 2011 3:35 pm
Hi, I have a source clip I want to edit in adobe premiere. It is 1280x720 (720p) but the moron set the frame rate to 30fps.
30fps video is outside the spec for 720p format and won't display in premiere. (You can only do 23.976, 24, or 59.94 for 720p content).
What's worse, it was presumably shot in interlaced, then post-blended to become progressive, so wherever theres movement, theres blurry blended frames, and it looks pretty bad. I've already scolded the gentleman and told him theres absolutely no reason he needs to be shooting in 720i for 720p target video. And I told him that if he's at least going to convert interlaced content to progressive from his HD camera, to use interpolation instead of blurry frame-blends. But what's done is done.
In order to edit this video, I have to convert it to standard 720p frame-rate spec, which is going to be 23.976 or 24 (59.94 is not an option).
Obviously when I do frame rate conversion (in something like vdub) to 24, it highlights/heighten the blurry effect and makes it even worse.
I was thinking of using the decomb filter to do a simple decimate to kill the blurry frames entirely and take it from 30 fps to 24 for proper 720p spec for importing into premiere.
So far I haven't had alot of luck (probably doing something wrong).
This clip "technically" isn't interlaced, so I have no purpose to specific TFF or BFF in decomb?
I don't know quite how to set decimate properly to completely remove the extra blurry frames and take it to 24fps.
Any guidance would be appreciated!
Thanks in advance for a great program.
P.S. If you have another plugin/program that you think would better do this, please let me know.
