625/50 do they mean PAL?
on May 4, 2009 at 11:33:15 pm

Hi,

I need to deliver an Standard Definition 16:9 digibeta tape to a company in France.
They sent me a Tech Spec Packet which states:

"Video signals shall be produced in 4.2.2 format, 10 bits 625/50"
I'm assuming this refers to the PAL format.

However in the same packet it also states:

"The signal shall never have been PAL or SECAM coded"

What exactly do they mean when they say "coded?"

I plan to layoff to 16:9 (720x486 anamorphic widescreen) NTSC Digibeta and then make a PAL conversion. That's what they want right?

Thanks everyone.
I love this site.

In this context I believe they are referring to PAL as in composite. You're correct in that 625/50 is "PAL" frame size/rate.

well

stricktly speaking pal is of coarse a composite standard whith 625/50 they mean digital component normaly SDI in 50HZ with indeed the resolution of 720x576. in your country they will call it 525/60 with a resolution of 720x480
what they are trying to say is that the material may not be framerate/norm converted in the composite domain.

greet
Maurice
