October 1, 2009 at 4:34 pmI guess that with the “Frame Control OFF”, Compressor just repeat certain frames to reach the 30fps.
No much difference with adding pull-down.

October 1, 2009 at 5:23 pmThanks Rafael. Thats what it looks like as I step through the clip. Works nice. I guess this is compressors way of adding in pull-down. If I had After Effects, I’d use it. But this is good enough for now. Thanks and thanks to everyone else for their comments. appreciate it.

October 1, 2009 at 6:27 pmWhen adding pulldown to SD/HD footage to run at 29.97, you should see interlacing. What you are seeing now is probably 2224 pulldown, meaning a frame gets repeated after every six fields.
What you want to do is turn frame controls on and leave the scaling to best, deinterlacing and retiming set to fast. Even though it is counter intuitive, you should set the output fields to Upper (I think this is a bug of sorts in Compressor), but in the ProRes QT dialog (which is in the format tab) you set the metadata to Lower. This results in a 29.97 file with 3:2 pulldown and it is properly flagged as lower field first.
If you upload two seconds of your 30pN footage, I can send back a two second movie proving the settings work.

October 1, 2009 at 6:33 pmJeremy, thanks. But I don’t want interlaced footage. I want to keep my sequence progressive. This is nto for broadcast. Our playback is on computer monitors via keynote, DVD and web. Interlacing looks bad on computer monitors. Can I not stay progressive? Why go interlaced?

October 1, 2009 at 6:42 pmSorry, maybe you missed that part. I need to go 30 because I’m cutting a case study video that contains TV spots at 29.97, along with the majority of the footage. My settings are above and set to SD 29.97. Extra filler footage we shot with the HVX 200 was at 720p30PN and I downconverted to work with the TV spots and its looks and works well. I’d rather downconvert to SD than upConvert to HD. But I need my older 720p24PN footage to work with that SD sequence.

October 1, 2009 at 6:47 pmYou should put everything in a 720p60 timeline.
Those tv spots you have, are those progressive?

October 1, 2009 at 6:57 pmThe TV spots are SD and interlaced. In order to make everything Progressive, I’ve converted them to progressive as well. I’ve got a lot of mixed footage, from HVX 200 stuff to screen and web capture from Snapz pro. Everything but the TV spots are progressive, which is why I converted them using Compressor. I knows its not ideal but it seems to have worked well. No real quality loss in going from interlaced TV to progressive.
I don’t want to go to a 720p60 timeline because upConverting my SD footage doesn’t look as good as the downcoverted HD footage.
Is a ProRes SD sequence at 29.97 not good? I know thats typically an interlaced format but again, I want everything to be progressive.
Sorry, if I’m confusing you, but being self taught, I get confused quickly when it comes to this sort of thing. Its one thing to be able to edit and see the finished product buts its a whole other can of worms to deal with the tech stuff, i.e. frame rates, aspect ratios, interlacing vs progressive and how to do all this properly.
