Ok so apparently the HPX170 and HVX200a don't shoot in 1080p/60p or even 1080p/24p as it seemed from previous descriptions. So according to the brochure the 1080p progressive is the initial scan signal coming off of the CCDs but cannot record in that format. So my question is how would the 1080i/60p work for us compared to the 720p/60p,30p,24p
In fact how can we even have 1080 interlaced scan at 60 progressive frames per second?
Is it better to just record everything at 720p for a full native progressive scan?
Also I understand the variable frame rates like 48p are used for cranking/slow motion effect. However wouldn't I also be able to export from final cut 7 at 48p and have in playback at 48p?
Sure both shoot 1080/24p- please send a link to a Panasonic brochure that says otherwise. :) Over and undercranking is derived by shooting at a specific frame rate over a specific recording rate. 48fps frame rate over 24fps recording rate = 2x slow motion. 12 fps over 24fps = 2x fast motion and so forth. All this is pretty well explained in the manual you get with the camera. I also cover this thoroughly in my training course for the HVX200
It's called 1080i/30p because it is 30fps Progressive recorded in an interlaced stream. DVCPRO HD is an interlaced only format in 1080, recording interlaced streams of 60 fields per second; there is no such thing as 1080p in DVCPRO HD. However, the images being recorded are truly progressive; they are merely being laid down to tape or card or disc in an interlaced stream. Each frame is recorded as two or more fields, depending on the frame rate. For 30p, every frame comprises two fields; for 24p, some frames are three fields.
(This explains why you can't get 60p in 1080 DVCPRO HD. Each progressive frame requires two interlaced fields, so you would need 120 fields per second to record the 60 progressive frames; there are only 60 fields available in the format.)
