Archived from groups: alt>movies>cinematography (more info?)

Hello everyone,

I just finished a feature on a DigiBeta PAL. I have a rough cut (110 min) form
a 12 hour footage. About 30 min of the footage is in Kodak 500T.

I wanted know if there is an advantage to:
1) up converting DigiBeta 50i to 1080i HD,
2) telecening the film to 24P and do full color correction

Finally convert all material to film?

Any suggestion?

Thanks,
Jay Bala.

Is the 500T material in 35mm or 16mm?

If you're talking about a film-out, there's not much advantage to converting
it to HD first, unless you want to use HD as a digital intermediate setp for
the film material, in which case it would be better to create an overall HD
master with the film footage transferred to HD, intercut with the PAL-to-HD,
rather than transfer the film to PAL first. And I'd use 25P HD, not 50i HD,
converting the 50i PAL to 25P HD.

But if it's 35mm footage, then just transfer the PAL to a 35mm negative and
then cut the 35mm material into that.

That's a big "if". Depends on your footage and what needs to be done to it.

PAL has to be converted from 50 fields into 25 whole frames anyway to be
transferred to film, so there's no advantage to keeping it interlaced-scan
in HD when they'd just be converting it to 25P before the film-out. Of
course, it probably depends on how well the conversion from 560/50i to
1080/25P is done.

In my humble opinion it's best NOT to transfer the digi and film to HD
unless you know exactly how the machines handle it. Day for night can
be corrected on film rather well depending on your color timer and
lab. The digi can best be color corrected before transferring it to
film. Last film I did containing film and tape I decided to do it this
way and it saved me a lot of time, money and worries by staying on the
original source as long as possible.

The true gain when it comes to HD is when you decide that some of the
35 mm material is going to be worked on in a 2k environment. HD can
then give you an overall good look because all of the 35 mm is going
to look the same. But if there is no need to go 2k, there is little
need to go HD.
