24p 60i DVD encoding
I’m talking with the company who my distributor hired to author the DVD of our film. The film is mastered as a 1080p23.976 AJA 10bit RGB 444 project. The DVD company is asking for an anamorphic DigiBeta for encoding. It concerned me, because I wanted it to be a 24p DVD so that people with all these new TVs and HDMI DVD players can see a beautiful progressive scan DVD and have less frames per second allowing for better compression. I asked the company about 24p and their response was that NTSC DVDs are 60i. They acted like no one ever brings this up with them. They do work for the studios who also supply DigiBetas, they said. Do good hardware encoders remove pulldowns if I supplied a DigiBeta? They said I could supply HDCAM, but acted like it didn’t matter. Am I mistaken about native 24p DVD encoding? Or are they just unaware of the technical aspects of encoding? The guys I spoke with weren’t the tech guys.. execs or something. I’m supposed to talk to one of the tech today and want to have my facts straight.
I’m worried. Your film gets encoded once. I want it done right.
Can anyone clarify any of this for me? thanks!!!

24p is not supported by DVD and is not really used in Blu-ray either. Instead it’s 23.976p. NTSC (DVD or digibeta) runs at 29.97, and encoding from digibeta is standard practice. They can likely remove the pull-down from the dbc (e.i. set the 23.976 flags), but they will need to set-up the encoder to do it, and make sure the pull-down settings are correct.

thanks. Sorry, I was just saying 24p as a shorthand for 23.976.
So, do I need to make sure frames are flagged when the DigiBeta is made. Or would the encoding hardware pick up on the cadence?

Unless the encoder is told to look for cadence it will make a straight 29.97 stream. Who’s gonna carry your film, btw?

I just spoke with their encoding guy. They said it’ll be 29.97. But that progressive scan DVD players will reverse telecine the video. The company is CinRam.

Sean,
Small world. I work for Cinram, but in the Blu-ray department. To answer your question from the last post, the encoder will pick up on the cadence as long as it doesn’t break. Make sure that all the post work is done at 23.976 and the only time it goes to 29.97 is when it is being put to tape.

thanks, Jeff. btw, the distributor is ‘considering’ BluRay, but i think if you translate it that means ‘sorry, but no’.

Welcome Sean. What studio is distributing the film here in the US? We’ve been working with some of our clients to find a way to lower the cost of getting into Blu-ray. Mabye your distributor is one of them.
