I think I got it Brian. It wasn't letting me choose an aspect ratio or frame rate, but the default seemed to capture fine, and cinema tools was able to reverse telecine properly.
Thanks for the work around! Alphonse |

Still looking for a Mac-based workflow that I can use for editing progressive from the V1U, which doesn't involve down-rezing... any ideas?

Greg,
Read Brians workflow in post #6 of this thread.. It doesn't involve down-rezing in any way. It works but you can't batch capture. |

Yes, it really does seem to work
[QUOTE=Brian Williams]I just shot and cut a little two minute piece so that I could shakedown the camera and the workflow with Final Cut Pro.
Worked pretty nicely. Shoot 24p Scan A mode. Capture in Final Cut as Apple Intermediate Codec 1080i60. Open your capture scratch folder and, one clip at a time, right click the clip and open with cinema tools. Do not move the playhead!! choose reverse telecine, be sure conform to says 23.98 and near the bottom of the screen choose _CD_. After the footage has been pulled down you should see no interlaced frames of any kind. Create a new AIC 1080i60 sequence in FCP, but change its frame rate to 23.98 in sequence settings (you'll see the field dominance switch to none). Our V1U came in last night... Took it out of the box and set up. Shot on a Sony V1U set for 24pA. Manual settings for everything. Brought the video into FCP using the AIC. Reversed Telecined with CinemaTools and then rendered out using the H264 Codec so people not running FCP could check this out. The footage is just some traffic that was passing by when we set the unit up. ftp://demo:demo@ftp.gotfootage.com User: demo Pass: demo I will leave this up for a week or so if anyone wants to check it out. |

Has anyone been able to get 30p to work in FCP?

I wrote this for VASST, detailing how to remove the pulldown without using the AIC:

Problems with 24pA recording and capture...
With many, many thanks to the contributions of others on this topic, I have been developing a workflow for capturing 24pA on a V1U and editing on a 1080-24p timeline in FCP. I've been pulling out what little hair is left, wrestling with the reverse telecine (or 24p Advanced pulldown removal), but I think I have found my problem:
My V1U seems to be recording standard pulldown (2:3) even when set to 24p Advanced (24pA) mode! Here is what I have worked out for capture: 1) I can capture via firewire as 1080i HDV, preserving timecode. 2) I can capture to the Apple intermediate codec. This loses timecode, so that recapture (e.g., for an uncompressed on-line) isn't easy. 3) Or I can capture from the decklink Intensity via HDMI into the DVCPro HD codec (need a RAID to capture uncompressed) - again, no timecode. 4) I can transcode (using Export via QuickTime Conversion) from HDV into a more robust codec - AIC, DVCPro HD, the beta CineForm HD, Avid's DNxHD, even XDCam. All these work, but I haven't looked at issues of dynamic range, vis any conversion to/from RGB... 5) I get stuck on removing the pulldown. The clips were all shot with the V1U set to 24pA, I've triple checked. But FCP doesn't recognize them as advanced pulldown (2:3:3:2), and Cinema Tools reverse telecine dialog doesn't allow selecting the 2:3:3:2 cadence. BUT, in messing around I have found that my clips, shot at 24pA seem to be 24p! Stepping through the frames, the cadence is normal-normal-blended frames-blended frames-normal (or 2:3:2:3 in terms of fields). Using Cinema Tools to remove that standard pulldown yields a perfect 24p clip! What gives? Busted camera? Did I miss a setting? Any more advice on workflow here? I know, we all hope FCP will become V1U aware real soon now, and that the CineForm codec for Apple will be able to capture soon. Why can't FCP capture video via HDMI but use firewire for deck control and timecode? Ricardo

It IS recording 2-3 recording. Curious where you read it wasn't.

Thank you!
Whoa - I am not sure where I picked up the notion that the V1's 24pA mode used a 2:3:3:2 cadence. But now that I review things, it all makes sense. For anyone not following this - 24pA uses the same 2:3 cadence as 24p, but resets with every start/stop of the camera, thus easing batch conversion.
So my workflow seems good: 1) Acquire 24pA -> HDV (capturing timecode) 2) Transcode to another codec (AIC vs CineForm vs DNxHD vs ?) 3) Remove pulldown with Cinema Tools 4) Edit at 24p 5) (Optionally re-capture for uncompressed on-line) Any comments on intermediate codec to use, or the means of transcoding? Thanks again, Ricardo P.S. I just bought a copy of Steve`s eBook (as a show of thanks for participating in forums like this).

This provides a path for 720p and 1080i HDV shooters who have been totally dependent on Apple. Of course, if Apple comes through -- this provides a second solution. Hope you find my book useful.

24p-straight pulldown 24A-Cadence always starts with a new 3:2 set of frames every time you start/stop recording. GOP format doesn't benefit from the 24pA that you are likely thinking of from the Panny.
