What is the Official XL-H1 24F FCP Workflow?
on Jun 16, 2009 at 6:49:46 am

Hey Everyone,

I know this has been an issue for a while, but now that some dust has settled I expect it has been worked out, however my Googling can't find any solid answers.

I have an original Canon XL-H1, with HD-SDI output.
I would like to shoot in High Definition and capture in the 24F mode with proper pulldown.

I know that Canon jumped the gun on the official 24fps HDV Spec when they released the XL-H1, and that they may have revised the method with the recently released XL-H1s camera, along with the other s series camera updates.

But what method works best with the original XL-H1?

If anyone can point me to a solid workflow tutorial I would be most appreciative.

I can shoot to HDV tape, or I can shoot to hard drive through a AJA IoHD.

If it helps, I can use the IoHD to make the footage 720p. But if a 24fps 1080p format can be achieved, I'd like to try that.

I remember reading something that the new IoHD software can now recognize 1080i 24Psf (progressive segmented frames), however, the caveat was that only the new s series Canon HDV's flag the footage properly over HD-SDI out.

Any tips, hints or links in the right direction will be much appreciated!

Thanks,

Jesus

I found this:
http://www.sony.ca/hdv/files/white/HDV_Progressive_Primer.pdf

On page 12 it claims that NATIVE Progressive recording is part of the HDV spec. (Recording 12 frame GOPs to HDV tape, twice per second). I never knew that.

It also says that "some cameras" called this 24F Mode.

On page 18 it goes on to say that this 24P or 30P 1080P signal can be captured over iLink (firewire).


This is news to me. Does it jibe with what other understand to be true?

Again, is there a recommended FCP workflow?

Does the XL-H1 embed any "flags" in the footage that FCP or COMPRESSOR can read to capture or pull down the footage correctly?

Thanks,

Jesus

So acccording to here:
http://www.dvinfo.net/conf/canon-xl-h-series-hdv-camcorders/76271-fcp-24-f-...

Which came from here:
http://www.hdforindies.com/archivedarticles/2006_09_01_archived_article.htm...

Native FCP 24F Presets have been around since September 2006[?!] FCP 5.1.2? Hrmpf!
Well, now I don't know why I've had trouble with this in the past...

Adobe offers no date on when they released their updates to add 24F and 30F Presets for Premiere:
http://www.adobe.com/support/downloads/detail.jsp?ftpID=3408

http://www.usa.canon.com/app/html/XLH1/frame_rates_formats.shtml

Sorry to have bothered people if indeed this is a non-problem. Well, now that I expect it to work, I'll test some footage and hopefully see gorgeous Progressive footage over Firewire!

Next I'll try to find the AJA IoHD 24F ProRes 422 workflow!


Thanks,

Jesus

Just to confirm, I was dumb/ confused/ mislead before I started working on this. :(
But NOW I know some stuff for certain. ...er, pretty much.


With the 1st Generation Canon XL-H1, if you record 1080 to HDV tape and choose the 3rd position for frame rate, you will record 24F.
This footage is like an HDV version of "24p Advanced (2:3:3:2)" on the DV NTSC format Canon XL2.
This format is also, called "Native 24P" on the HV40 and newer Sony cameras.

Final Cut Pro can capture this format, without issue, if you use the proper Easy Setup: "HDV 1080p24 Firewire Basic."

* * *

This format is HDV and as such has a 4:2:0 color space and is 1440 x 1080.

But if you have FCP 6.0.2 or newer, you have the ability to capture HDV footage DIRECTLY into ProRes 422 and even ProRes 422 (HQ) [10-bit].

A man named Andrew Balis figured it out and even produced some FCP Easy Setups that you can download:

http://www.kenstone.net/fcp_homepage/capture_hdv_prores_fw_balis.html

* * *

I recently learned that this is also the format of 24fps that Canon has added to the HV40.

This was super confusing to me, because everyone has been touting that the HV20 and HV30 can all do 24fps, but that you have to remove the pulldown afterward.

I am really surprised Canon didn't simply include the 24F HDV "native" format from the start.

The HV10 can read 24F from the XL-H1, and even calls it "HDV 24F" on screen during playback. But for some reason it cannot record INTO that format.

* * *

I have also confirmed that the 1st Generation Canon XL-H1 cannot feed its 24F mode into an AJA IoHD.

From what I've heard, the special footage flags are not sent out over the HD-SDI.
