Ingesting 1080p60/, 1080i60 (or 1080p24) frame rates?

Hello,

I just received a new Sony PJ-790V Handy Cam. Newest tech from Sony. That said, I have FCP7, and other than moving to FCP X (unsure if there is an advantage to doing so), my scenario for your good selves is to be initially based on FCP7 please...

This camera shoots AVCHD 1920x1080, in frame rates of 60P, 60I and 24P. The first two is where I'm confused.....

Have not yet filmed much since opening the box yesterday, but it is my understanding that FCP 7 may not want to play nice (after ingesting with Log and Transfer) if using 108060P. I have no opinion (it's why I'm writing here...) if my 2 ultimate end products desired will work/look best as a P or I.

>> End product 1: Day for day end use- 1920x1080 H264 10-15mbps (after QuickTime or Compressor) movies played on my HDTV. The tv is capable of both 1080P and 1080I.

>> End product 2: Archived original movie (mastered from FCP 7 editing, exported as QT movie, Pro Res LT).

Sorry to get so wordy here- truly.

1) What will FCP 7 ingest and work with?

2) Is there an advantage to be gained by making the move to FCP X?

Respectfully,

Bob

Shoot either 1080p 24, 1080i60...or if there is a 1080p30, go for it. 1080p60 is a non-standard format...really only used to shoot footage meant to be slowed down for smooth slow motion in post. Only the web can play back 1080p at 60fps. TVs do 30fps (1080i60 or 1080p30) or 24fps (23.98...1080p24).

Thank you, Shane.

Am I correct in saying that 24P would produce a more 'film like' look over 60I?

Is there much of a difference in shooting action vice still scenery here?

Cheers,

Bob

Yes...films are shot at 24fps, and sports/news/soap operas are shot at 30fps interlaced (60i)

>Is there much of a difference in shooting action vice still scenery here?

If there is movement, you can tell the difference between 24p and 60i

Bob,

If you are curious about recording in 24p, you'll want to read up on the concept of the film panning.

Because you are recording at a 20% lower frame rate (24 vs 30) if you have much movement within the frame, the displacement of each element will be significantly greater. The result of high intraframe motion is a slightly staccato rhythm. Some like it and some find it induces epileptic fits.

There are ways to smooth it out. They generally require the ability to control shutter speed and/or employing a very deliberate panning motion. If you are working with a consumer cam, the first item is usually not in your control so you do need to understand how quickly you can move the cam for best results.

Best,

edit: fwiw if the material is low motion, I always record at 24p for a couple of reasons -

1. The file sizes are 20% smaller for a given period. This means I get that much more capacity/ recording time out of the card(s).

2. When converting to a steady data rate for playback, I have 20% more pixel information for each frame which means a higher quality playback.

also, If I'm recording action/ sports and the like, I'll usually record 60p. This gives me the option of time remapping (slo-mo). If I decide the material will work best as regular speed (i.e. not slowdown), I'll just convert it to 30p when ingesting it before editing.
