HDV 24p workflow by Solomon Chase (23.976 version)

[GreenScreenCinema]

@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.

@GreenScreenCinema

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?

man, that kid just seems that he will become a great person in this world.

[raphabadboy]

hi, really nice shot and work. please help me: my cam only shot 1080i. how to convert to 24p to get this film look. what should i exactly do? please help me :=(

[GreenScreenCinema]

I'm going to have to answer this question in about 5 parts.

Part 1

The Canon HV20 allows you to shoot in SD, HDV and HDV 24p (the more recent model adds an HDV 30p mode as well). To shoot in HDV 24p put the camera in Play mode, open the Camera Setup menu and under HD Standard select the HDV 24p icon. The HDV 24p icon looks like a film frame with the letters HDV in the middle.

Do not confuse this setting with the Cine Mode. In part 2 I'll explain the difference between this and HDV 24p

[GreenScreenCinema]

Part 2

Cine Mode is a setting that is found under Recording Programs. You don't want to use Cine Mode. The Cine Mode icon looks like a film frame with no letters in the middle (which is pretty much what the icon for HDV 24p mode look like).

Though the two icons are nearly identical, the Cine Mode setting plays some tricks with your aperture and shutter speed that you want to avoid. My recommendation is to shoot in HDV 24p without any additional in-camera effects (like Cine Mode).

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.

[GreenScreenCinema]

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.

[GreenScreenCinema]

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"

[raphabadboy]

hi, wow thank you very much for your time. But im using sony hdr-xr500. i can only shot 1080i :(

can you help me to converto 1080i to 1080p?

@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?

[GreenScreenCinema]

@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.

0:17 is a very simple but artistic use of colour! Love it.

[alphiux]

awesome vid! what shutter speed did you record at?

[GreenScreenCinema]

I used a fast shutter (TV speed) so that the entire image is stored on tape. Trying to get a film look via a shutter doesn't really work. The frames per second setting does it all for you. A slow shutter would just impair the image.

[TVTsteven]

this looks great man

what was your editing software just AE?

dang I need to figure out a 24p solution for vegas 7 or just get a mac haha

[PingaloBill]

Hey! Thank you for your video!!!

Maybe you can help me on this question:

If I record in 25p and then render (?) with 1920x1080 resolution, is my movie 1080p?

Nobody could answer me this question...so I hope you know this :-)

Ciao!

[GreenScreenCinema]

1080p actually means the video has a 1920x1080 resolution and the frames are progressive (not interlaced). So if you shot progressive (25p) and you rendered the footage in 1920x1080 resolution then, yes, your movie is 1080p.

To get the movie to look right, though, you need the correct pixel aspect ratio. If you shot HDV like I did then the original footage is actually 1440 x1080, and you need to use a 1.3333 pixel aspect ratio to get it to appear as if it's 1920x1080.

[PingaloBill]

Yes, of course. In 1440x1080 it's anamorph and doesn't look right.

So it should be possible to make a "Full HD"-movie (1920x1080p) Nice! Thank you.

And BTW, this video looks really really good. The best 24p movie that I saw so far on YouTube.

CIao

[eddieoak]

Silly question, but how do you know your 3:2 removal was successful? BTW, the footge is stunning!

[GreenScreenCinema]

You could analyze the file with an open source tool like VirtualDub (which lets you walk through the fields) and visibly check that the top field and bottom field in each frame contain the exact same image. If the fields are identical then the encode holds a true frame.

[jewrabs]

great vid im gonna buy this camera really soon.

TV-speed shutter. It was under-exposed 2-3 stops to avoid blow-outs

what does this mean?? hahah. what are the analog parameters on the hv20/30??

[TVTsteven]

TV is a setting on the camera that allows you to choose the speed of the shutter

and 2-3 stops under-exposed means he under exposed the image (cameras exposure control) to avoid blow-outs (really bright/white objects-ex. a sky)

[iagosanslpez]

what is the camera HV20 or HV30?

[GreenScreenCinema]

This was an HV20, but the HV30 is almost identical. The HV30 has a 30 fps mode that the HV20 does not, otherwise they are the same camera. Since the HV20 is an earlier model it's a lot cheaper, but being such a great deal they are also harder to find.

[leafsoup]

got mine for only 700 at circuit city (HV20, that is)... Of course I knew the manager though, lol.

[AnnexF]

Awesome video! Keep it up.

[GreenScreenCinema]

In Adobe After Effect click on File > Interpret Footage and then enter your cadence in the Remove Pulldown field. The Interpret Footage section actually has a great tool to help you figure out the frame cadence of your clip. Click on the Guess 3:2 Pulldown button and it will set the correct cadence in the Remove Pulldown field. This tool is far better than simply taking the 29.97 fps that is produced by the HV20 (when it writes 24 fps content to disk) and then trying to output a 24 fps movie.

[Jashan17]

how did you remove the pulldown?
