Proper workflow for HV20 24P - DVXuser.com -- The online community for filmmaking

DVXSanDiego · 04-07-2007, 01:24 PM

So, went to the Vegas section of the forum, and people are having issues getting HV20 24P footage into NLEs, i.e., no pulldown removal. Here's the link: http://www.dvxuser.com/V6/showthread.php?p=909283
My question is, since Final Cut is having the same issues, what NLE are people using to edit the 24P content from this camera. I am absolutely loving the footage I've seen, but without an NLE to edit it...
What NLE do people recommend for 24P HDV footage for the HV20, XL H1, etc.?
What workflow are people using?

i'm using FCP to capture, subclip and export. then i open them in QuickTime to figure out where the first frame falls in the AA BB BC CD DD cadence, and then to Cinema Tools to reverse telecine. FUN!

Des anyone know how premiere is handling this situation?

Yeah PP is a must.

Artscroll posted a workflow that's worked for him (on Windows). You can see his post here.

This works too:

1. Create a d2v with DGIndex
2. Load with MPEG2Source("d:\tmp\streetbasketball24p.d2v", cpu=6)

and then use this:

4. tfm(d2v="d:\tmp\streetbasketball24p.d2v")
5. tdecimate()

Thats all. You'll get perfect progressive frames.

scoemlek, I like your method. The process I had been using was working for me but a stray interlaced frame sometimes squeaked through. I made a little avisynth script similar to your guidelines. Of course everything in quotes needs to be replaced in respect to a person's machine and filenames and which version of AVISynth they are running. Download the plugins DGDecode.dll and TIVTC.dll and place them in your AVISYNTH plugins directory. Here is a working script after you create a .d2v file with DGIndex.

LoadPlugin("c:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("c:\Program Files\AviSynth 2.5\plugins\TIVTC.dll")
MPEG2Source("c:\Canon\cmon.d2v")
tfm(d2v="c:\Canon\cmon.d2v",-1,1,0)
tdecimate()

I got 23.976 pure progressive frames. I did notice that the colorspace is YUV. Has a conversion to YUV colorspace happened along the way? I'm not a colorspace expert, just something I noticed with the process you detailed.

How long are you guys finding the process takes? I've been using After Effects 7.0 to remove pulldown and outputting to uncompressed...but it takes a very, very long time. 4 minutes of footage is taking about 24 minutes. That's on a core 2 duo at 3 Ghz, with 2GB ram, and two RAID 5 arrays. I'm then bringing that footage into PP2.0

I spent a few hours shooting on the weekend...and the HV20 did really, really well in snow/sun conditions with an ND.9, + a CP, with the Brevis and 50mm at f4, cam locked at f4.6 to f5.3

The footage is very clean.

in cinema tools, im getting a little better than 1:1 in the reverse telecine process. less than three minutes for three minutes of footage. this is on a quad 2.0 G5 powermac.

@Artscroll
Take ConvertToYUY2 if you want to get 4:2:2 colorspace.

Yes, quality takes time

I will try Restore24 from scharfis_brain. It's one of the best IVTC Tools.
