16mm >>> Digital: Questions???

Recommended Posts

Hello,

If I convert 16mm to digital, what quality is better? Mini DV or DVC PRO?

 

And when I import to Final Cut Pro, what should my import settings be (for best quality)?

 

My goal is to not "dumb down" the beauty of film with digital editing.

 

Thanks!

DVC PRO HD.

DVC PRO 50

 

Best would be Uncompressed HD 4:4:4 1080p.

 

MiniDV = evil.

Just to clarify though, MiniDV. DvcPro, and DvCam all have exactly the same picture quality, i..e. 411 5;1 compressed. The "pro" formats DvcPro and Dvcam are just more robust versions of the MiniDv format, i.e. the tape runs faster to minimize dropout, they handle timecode better, etc.

 

DvcPro50, etc are different formats and are less common and more expensive.

 

 

And yes MiniDv does suck in many ways.

what is the compression rate of uncompressed DVDs

and much can you put on a 4G DVD? and what kind of

running time do you get from that?

 

You don't compress the files for storing onto DVD's, you just transfer/burn the QT files themselves to the DVD's as a data disc.

 

I don't know what compression your footage will be upon transfer, so I can't say how much will fit on a 4gig DVD, you can easily do the math though depending on your file sizes. And DVD-R's are pretty cheap nowadays.

Uncompressed QT transfer takes about 3.5GB for 2:30mins of a 100ft 16mm roll.

 

1080 4:4:4 zipped will fit about 1 min onto a 4GB dvd disk.

 

I highly advise to go with BlueRay or HD-DVD burners for optical disk archiving.

 

 

.... There are magnetic data tapes ....

 

DLT drives hold way more, and magnetic seems to last longer than optical for off-site data backups.

Buy an external hard-drive and have it telecine'd at 4:4:4 1080i HD.

 

Then, for archival purposes, you can back up those files on DVD's afterwards.

 

 

Recordable DVD's are really only reliable for a short period of time, 5-10 years or so. I have a pdf of an article from "restaurator" an archivist's publication in which a very methodical test of a wide range of optical media was tested and how well the media survived under different conditions. Unfortunately about the best result was 10 years without loss of data and the worst result was only a few months. The test was made with a wide range of conditions from ideal to worst.

 

 

We are currently in the middle of an archival project for a library which entails backing up or duplication all of the media assets of a US senator. Everything from 16 & 35 to Beta 3/4" Quad, vhs 1" etc. Much of the magnetic tape has had issues with mold and although the base is polyester and the material is ferrous the mold finds the organic binder (glue) to be tasty and when the mold has eaten through far enough the control tracks are lost or the entire helical scan is lost and there is no recovery of the material. That said tape does last significantly longer and better than optical.

 

Your original negatives will outlast all of the digital formats available today by a very wide margin and if they are B+W an order of magntude or 3.

Thanks Dennis

 

That is exactly the answer I was looking for.

 

Cheers

Thats some good info I need for this project. Thanks, I'll keep it in mind.
