Is their visable difference between dvcpro50 and 10 bit uncompressed? I have a job comming up and was wondering the way to go. The source was film teled to digibeta and now the on-line is in order. Thanks all

You tell me.
Do a test and of both and look at the picture on your NTSC monitor.
You and/or your client are the ones to judge.
We can all have our opinion.
Technically speaking,
the 10 bit uncompressed has more picture information
than does DVCPRO50, but not by much.
Technically speaking,
by the time it's edited, rendered to death,
dubbed and aired, if there is a person on this earth
who could tell me the difference by looking at the
air signal, I'd first off say they were lying, then
I'd say put money on it.

The real reason for using any codec other than uncompressed
anything is because of disk space. If you don't have
loads of it, then DVCPRO50 will do you well.
But for goodness sake, this is only one dude's opinion
among many.

Dan,

I have to disagree with you regarding your average person statement because anyone understands the importance of 8 bit versus 10 bit especially especially when it comes to color correction will indeed see a difference on air, on tape or even on vhs. Banding is a major issue which distracts visually and is one of the major reason to work in 10 bit instead of 8 bit.

It is not just about disk space but the level of compression, color space,resolution etc which are of concern to the client, editorial house etc.

Can the average person tell the difference between 35mm film and HD or mini DV? Some can and some can' but so what? If none of this really matters then why not just shoot in VHS to start with?

Can the average person tell the difference between a stock VW bug and a high performance Formula one race car. Some can and some cannot both vehicles serve a purpose to get the driver from point A to B. Except that one will actually cross the finish line in first place.

Thank you that is good advice there is about 90 keys and a load of color corection so I guess the uncompressed is the way to go. And Dan you hit it drive space is a factor over here.

i made images in dvcpro 50 pal with a panasonic sdx 900 and an hd lens
impossible to do such nice image in 10 bits with a digital beta camera !!

Tony,

I've fought all my professional life, over 35 years now, on having people
shoot and edit with the highest quality they can. When I say "average
person" was wasn't talking about your mother in law. I was talking
about the average production person...people with good eyes.
First gen DVCPRO50 is damn good and you can't shoot in
uncompressed 10 bit anyway, unless you lug around a Panasonic D5 deck
and run it in SD mode.

Sometimes I wish people would spend more time worrying about
the writing, the lighting, the audio and the video, learn how to use
a waveform monitor, and less time about what tape or format.
Lousy is as lousy does. Because when the time
comes and you have more resources you will shoot on the best
possible format, but that won't change your lousy directing
or your lousy production habbits. Not you of course Tony.
I don't even know you. I speak generally.

Off soapbox...on to make pictures today.
Dan

Dan,

FYI I shoot DVCPRO 50 as well as digi beta so I understand the merits of both systems.

What I was referring to was not origination but the ideal post production codec when dealing with color correction, lots of layered efx etc.
Issues such as severe banding have nothing to do with bad directing just bad technical information.

No one needs to view a waveform to see the negative implications of using an 8 bit system for an application that can benefit from 10 bit.

However not all projects need to go 10 bit if 8 bit when mini dv will do. In these cases a decision must be made regarding budget versus quality to decide which route is best.

Tony,
Well said.
I think you and me think more alike than different.

Regards,
Dan

peter, I find DVPRO50 to look exceptionally good if loaded from Digibeta via SDI. Looking at it on a 20" sony BVM with the SDI board, you are VERY hard pressed to tell the difference between it and Uncompressed. I've onlined plenty of lower end direct-to-market things with it, but for higher end jobs, especially with FX, I'll always go 10bit Uncompressed. Also you mentioned keying, then* defiantely* go with 10bit.
