Editing Issue with DVCPro50 and Format

[Shane Ross]

DO your sequence settings match the clip settings? Because DV50 is 720×480, and uncompressed SD is 720×486…so there might be something there. But I doubt you’d see the 6 pixels though…

Can you post a pic?

Hi Shane

I searched the forum to shed some light on a concern I’m having with a DVCPro50 project that was shot and ingested in 2007 as ProRes 422 HQ. We are versioning the show in English and I’m noticing black lines on the vertical edge of the frame. I thought that DVCPro50 was 720×486. Is it true that it’s only 480? How have you dealt with this type of issue.

I’ve checked the original French DigiBeta master and I see the same line in under scan. The show passed QC so I assume I can do the same this time around or should I blow the show up by a few pixels to be safe. That’s a heck of a lot of render time that I would like to avoid.

Thoughts?

Cheers, greg

I’m sure. It is only 480. [Greg Nosaty] “How have you dealt with this type of issue. “

Left it. It is outside of TV safe, and no network has rejected a show because of this format.

[Greg Nosaty] ” The show passed QC so I assume I can do the same this time around”

There you go. Things are fine.

Like Shane says, DVCPro50 is 720×480 like all DV.

You can scale the shots up in even increments 2% or 4% if you wish, but keep in mind, what you’re seeing in the FCP canvas is “full frame,” the blanking you’re seeing will be outside of TV safe.

Thanks Shane and David

Is there a way to adjust the the horizontal blanking width in FCP?

The horizontal blanking is on the tape itself…not something that FCP does. Again, this is outside title safe, and perfectly acceptable for QC, so I fail to see what the problem is.

If it bothers you, the only solution is to scale up in even numbered increments as I told you before. No one will notice.

There IS NO problem.I don\’t seem to see these issues working in HD and it\’s been 3 years since I\’ve worked in SD.

It\’s just a bit perplexing to see one thing in FCP, that is different, from what I see on the DBC deck whether it is set to H-BLK wide or narrow.

because HD doesn’t have these differing formats. SD is 720×486, from BETA and DIGIBETA and 3/4″ and MII and most other formats. DV and DVCPRO 50 just happen to be 720×480…so there is vertical blanking. That is their FORMAT…not an FCP issue. There is no 1920×1072 (as opposed to 1080) format that would compare. Everything in HD, no matter the format, conform to the same pixel dimensions (sorta…anamorphic exceptions, but they don’t count in this comparison).

DBC deck? Digibeta?

Correct, HD televisions and thus HD signals don’t have the same large area outside of TV safe. What do you expect, SD TV was designed in the 1800’s.

Here’s a taste of what you’ll find on Wikipedia if you look up the history of TV:

“As a 23-year-old German university student, Nipkow proposed and patented the first “near-practicable” electromechanical television system in 1884.[1] Although he never built a working model of the system, Nipkow’s spinning disk design became a common television image rasterizer used up to 1939.[2] Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on August 25, 1900.”
