to shoot or not to shoot (again about 720/25pn or 1080/25p over50i)

[simone.p]

hi,
here i am looking for some more help: i'll start shooting a short movie on monday and i use the HVX200, we would like to end on film but we are not 100% sure about if we really will...anyhow we decide to shoot with "Gamma mode cine like D" but the other big doubt that i thought was gone (shooting in 720/25pn or 1080/25p over50i ?) is back again because i got this mail back from a very good lab in switzerland:

"...I recommend to use 720p as recording mode. Panasonics HD format is 720p. The camera will only upres from that if you use any 1080 setting. The upres can be done in a better quality in post.
720p is actually 720 50p. This is what most editing platforms take. 720pn is a true 720 25p. Few editing platforms can handle this."
(by the way what does it mean upres?)

and so after we decided to shoot in 1080/25p over50i format now we don't know what to do..
Is there anybody that could help us to solve this???
thank you in advance for your precious helps!

deep silence is answering me..
is there anybody out there?

They're wrong. Shoot 1080/25p, and consider using a different lab that understands how the footage works. 1080/25p is better, higher res, and less compressed than 720/25pn. The notion that it's an "in-camera up-rez" is just plain incorrect.

Simone, the HVX actually works the other way around -- it always derives the 720 and 480 images from a 1080P image.

Wow. That's a bit unsettling that a lab can get it so wrong...

it always derives the 720 and 480 images from a 1080P image.
Because chip is 960x540?

[THoff]

Yes, the CCDs are 960x540, that is a well-known fact. Like many cameras, the HVX uses pixel shifting, in this case both horizontally and vertically to create a 1920x1080 image. Pixel shifting should not be confused with resizing or interpolation.
