  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

DCP Creation

Resurrecting an old thread here. Now that a couple years have passed what would be the best way to convert 23.98 to true 24 (no Teranex) without audio slip for home system DCP creation?
I'm confused. Tell me why you need 24.00fps for delivery. I have never, ever seen 24.00fps files for a home video project. Even for a DCP, you can still use 23.98 all the way through delivery. It's more an audio issue than video per se; the standard will work either way.

Having said that, a normal Sony HDCam-SR machine can playback at either 23.98fps or 24.00fps just as a menu item. It's another step, but that might be cheaper than a Teranex. Though now that I think about it, I believe Teranex was just purchased by Blackmagic and they cut the price on it by about 2000%:

Thanks for the reply. It's not home video but cinema bound and 23.98. Vertically integrating and attempting do to DCP from my edit suite. I read that the only accepted rates for DCP were true 24 and multiples thereof for the conversion to XYZ color space? I'll be a happy man if that's incorrect. Can you elaborate?

EDIT: Full quality SMPTE output has true 24 as only base option. Only acceptable 23.98 is MPEG-2 (Deprecated) at 1920 x 1080 which I won't be using. I'll be looking to make a fully quality 2K and 4K DCP.

I have access to a Teranex at a place I used to work, but found it in the past years to never be the best option when cross converting.
 
23.98 to 24

23.98 to 24

If you are on a Mac or have access to one with Final Cut Studio, you can use Cinema Tools to conform your file from 23.98 to 24. Your audio will resample to 48048 Hz which will screw up your workflow, but you can do a quick and easy resample by importing the file back into Final Cut Pro and re-exporting.

BAM! - 24fps with 48kHz audio.

Thank you Garrett! Great solution, the old standard Cinema Tools. Test conversion looks just fine, no noticeable judder, awesomeness.

It looks like you've had some extensive experience with DCP, you mind a few more questions?
Say after converting video (picture only) to 24p in Cinema Tools and I didn't want to recompress the high quality file in FCP to get that 48kHz audio, what if I exported final 5.1 audio by itself and tacked it onto my Quicktime master, within Quicktime? I only ask because I've encountered a few situations where editing tracks into and out of Quicktime, within Quicktime, hasn't translated well.

Also, do you think this whole method will result in any audio slip?

Thanks bud, I appreciate the great help!
 
If you've never done a DCP before, I would strongly suggest you hire some experienced people to do it. I would recommend both Simple DCP and Quvis as companies who deal with indie filmmakers all the time, know all the potential pitfalls, and can help you through the process at an affordable price:

I have no connection with either company, except for having seen them do very good work under tight schedules.

Hi!

You may also try out our FinalDCP software if you like. We can convert directly from various format such as RED R3D, DNxHD, ProRes, CineForm, Edius HQX MOV, DPC, TIFF, JPEG2000, JPEG2000-MXF and many more into a DCP. We also allow on-the-fly rate conversion from 23.976 to 24 or 25 to 24 etc. Its drag'n'drop and we have a FREE Edition that you can test drive.

We do also support multi-threading and multi-processing using a very simple to use render farm approach, so we can go well beyond realtime performance, depending on your computer systems. Its for MAC and PC.

We are currently implementing several nice features, such as cropping, scaling, color pre-compensation (to enhance the contrast of material, especially when it has some flaws such as having it legalized twice etc.). A new build is expected before IBC.
