DVCPRO
- HD
Published : 15th October 2003
Today I asked for the difference between a DVCPRO regular tape and a DVCPRO
HD tape... and someone told me that is the same tape, you can use the
regular DVCPRO tapes in a HD camera with the same results.
Is this true?

Here In NYC I've used DVC50 92 minute tapes in Panasonic 27 F cameras
and recorded HD on them No problems. You get 46 minutes of recording time
with a 27 F. Of course, you have to specify the less contrasty HD tape
instead of the normal stuff

Just learned it myself a few months back from someone on the CML.
Yes the DVC 50 which comes in a 92 minute load is identical formula as
the HD just a bit cheaper.

DVCPRO, DVCPRO-50 and DVCPRO-HD all use the same tape. Don't forget though
that runtime is different! 60 minutes on DVCPRO are 30 minutes on DVCPRO-50
are 15 minutes on DVCPRO-HD.

Yep! Burned alot of it without any problems. Same stuff. 126 will give
you 33 minutes.

Does the low contrast HD tape work better than using the normal HD tape
and overexposing the image by one stop, then having the lab pull process
the tape one stop? Inquiring minds want to know.

Actually I shoot high contrast tape in low contrast situations and low
contrast tape in high contrast situations....and not to confuse the issue
I just shot some 100fps material with '45 on a sunny day and I think the
Hi def folks better go back and recalibrate their imaging model.
Oh yeah, the stock had been in the fridge for 3 years too.

I store new tape stock in the freezer. It helps to keep the Earth's EMF
from fogging the tape.

Just take care. If you bounce from brand to brand, the tape lubricants
conflict.
A lesson I learned on my Canon XL1.

Dave, the lubricant is embedded in a Metal Particle tape, which is what
the DVCPRO standards are, and there is no issue. Metal Evaporated is the
DV and DVCAM tape and there indeed one has to be careful.
Hope that helps

Also, in reference to a recent thread, aren't all the DVCPRO tapes the
same formulation, from 25 to HD, differing only in labelling, and can
be used interchangeably?

Not exactly the same formulations. The 25's are not 'packed as tight'
in terms of particles as the 50's which are equivalent to the HD's, but
I have checked the specs of the 50's compared to HD's and they are identical.

Well, that’s good to know. I thought all of the tape was the same.
What about brands, ie. Fuji to Panasonic?

There's no need to pull process. All the lab has to do is run the tape
past a large, powerful magnet. That pulls the contrast back quite thoroughly.
As a bonus, the tape can then be re-used, saving the producer a bundle.

After checking with the tape guru over here, it seems that DVCPro, DVCPro50
and DVCPro HD are in fact EXACTLY the same with only a difference in the
label; same formulation, same particulate matter, same coatings. This
is universal as Panasonic certifies all factories that license/manufacture
DVCPro tape (Maxell, Fuji etc.)
This assures 100% compatibility and reliability. So there should never
be tape failure more often with a single brand of DVCPro over any another.
