Back to interlaced?

Recently I shot a 5 minute music video and went for the film look by shooting 720pn 24
progressive. It looks OK when viewed on a TV. In order for it to look its best on a video projection system, should I go back to interlaced video? If so, should I do this when rendering out of FCP, or when exporting to a QT file? What settings?

Or should I have shot this interlaced in the first place since it will never be on film?:shocked:
 
Stay progressive would be my opinion. Progressive is fine being displayed on interlaced systems.

Interlaced looks like crap on progressive displays, though.

Forgive my ignorance, but if the NTSC TV system is interlaced, and neither are
computer monitors, what displays are progressive? The new HD monitors?

Yes, the 1953 NTSC is interlaced.

mainstreetprod, you need to understand the reason for interlacing. In the 40's-50's a tv camera could not record/broadcast full frame (progressive), so it recorded two 1/2 frames which it interlaced together... NTSC doesn't care if your image is interlaced or progressive. Most of the commercials, music videos and broadcast design stuff I have worked on, have been rendered in full frame (progressive). You can do 30 fps or if you shoot at 24p, then you should add a 3-2 pulldown for broadcast, since NTSC is roughfly 30fps (29.97) and if it's a long piece , it"should" be drop frame.
Then again I alway work/output non-drop, and let the network add the drop-frame in the dub. process when/if needed.
 
apply a 3-2 pulldown...

Does this advice apply only for over the air broadcast, or also to prepare
a DVD or to be shown on a video projection system as I mentioned earlier?
 
There is no magic formula that will optimize your video for all displays. Most projectors have a native refresh rate of 60hz similar if not identical to broadcast's 59.94. Somewhere along the line a pulldown is going to happen. Either you'll do it, the dvd player will do it, or the projector will do it. If you want your footage to look it's best try and avoid dvd altogether. A budget solution is to run your computer straight into the projector. This will give you near HD or possibly even true HD depending on the projector's native resolution. Apply the pulldown and scale if you need to go to an sd format DVD, DVCam, Digibeta etc.,
