HDV 24p workflow by Solomon Chase (23.976 version)

This sample follows the HDV 24p workflow created by Solomon Chase for his short "Rainy Day Cinematography". The original footage was shot in HDV at 24p with a TV-speed shutter. It was under-exposed 2-3 stops to avoid blow-outs. In post the white and gamma levels were then bumped up to compensate (using After Effects). The captured footage also had the 3:2 pulldown removed from it (getting it back to 24p). Finally blues were color corrected down (highlights -20%). This is an improvement on my response video which did not properly remove the 3:2 pulldown.

@Zackmo92 You can remove the pulldown in AE, render out full frames and then create a 24 fps project in Premiere and import the footage back in (as 24 fps). That's one simple route. Another route is to use Premiere to do the 3:2 pulldown removal (and not AE). Both environments allow for 3:2 pulldown removal, so it's up to you where you want to straighten out your frame cadence. My preference is AE because the AE version of interpret footage has more options than the Premiere version of the tool.

Thank you very much. I've been looking for ways to do this for a long time, nothing seems to work for me until recently. This morning I was up late trying to figure it out. What render settings do you use/would you recommend after you remove the pulldown in AE?

@GreenScreenCinema

After Adobe AE interprets the footage, removing the pulldown, what do you do about getting it back into Premiere to edit? Or whatever NLE one would use, do you render it out? If so, what render settings do you use for the HV20?

Part 5

In After Effects you can select an asset and then click on File > Interpret Footage > Main and the "Interpret Footage" tool appears.

This tool will get your video out of its 29.97 fps shell. Simply click the "Guess 3:2 Pulldown" button and the tool will find the original 23.976 frame cadence. Though the tool says "Conform to frame rate 29.97" you can simply ignore that. Down in the "Fields and Pulldown" section there is another message that says "Effective framerate of 23.976 ftps"

Part 4

To fix this problem you will have to remove the 3:2 pulldown. Luckily the Adobe Creative Suite comes with an incredible tool for doing this called "Interpret Footage". The full version of the tool can be found in Adobe After Effects, while a neutered version of the tool can be found in Adobe Premiere Pro. Since we have to correct white levels in After Effects anyway we might as well use that version of the tool. So now you'll need to close down Premiere, open After Effects and import.

Part 3

After shooting in the HDV 24p mode you'll need to capture the footage to a PC with Premiere. Once you are done with the capture process the first thing you'll notice about your files is that Premiere does not think they are 24 fps. Premiere says they are 1440x1080 at 29.97 fps and Premiere is correct in this regard. Because of the way the HDV standard was implemented your 24 fps video is actually stored in a 29.97 fps wrapper on disk. It's as if 3:2 pulldown was added to your content.
