To jump in here Blackmagic is about a generation or two behind Kona on a couple of things this being one of them. However the decklink does pass through the RP188 data so you can use the DVCPro HD frame converter tool found in tools menu. But I don’t know if using the ProRes setup will screw this up.
[Brad Weston] “using Apple’s ProRes codec (looks fantastic by the way… for those interested there is definitely a visual difference between DVCProHD and ProRes when capturing from an uncompressed source)”
This I’m not getting. Your source is compressed. You are capturing from DVCPro HD tape recorded in the DVCPro HD codec. You are not going to get any better then that even if you capture in 10bit 4:4:4 uncompressed. Your source is your ceiling.
I would try the frame converter tool. If that’s a no go. You’d be better off recapturing using the Blackmagic 720P 59.94 DVCPro HD easy setup then pulling the duplicate frames in all your footage. I assume color correction is planned for your project and if you use Color you can render out of Color in ProRes HQ if that’s what you want as your final. Just note if you lay this back to DVCPro HD tape it will be recorded in that codec.
If pulling frames is really more of an option then recapture I’d look into renting a Snell & Wilcox Ukon. Which can correct broken cadences.

[Aaron D Hose] “standard def (720×486), no fields, 29.97”
was this how it was rendered out of Maya?

Can’t tell much from the still. As a guess is the animation and the video it is cross dissolving to/from on the same video track? If so I have had render issues that look like banding on steroids. The work around was to put them on different tracks and use the cross dissolve on the upper track.

I had a similar issue when trying to output to a Sony DSR-11. I had to go into the deck’s settings and select firewire as TC source. Then to black the tape with TC starting at 58;00;00 I had to use an app called Simple Video Out.
In FCP I created a sequence starting at 58;00;00 and filled it with slugs for however long I needed to black the tape. Exported that sequence as a self contained QT, then used Simple Video Out put the black, TC and all, onto the tape. Why FCP could not do this directly is a mystery.
Once blacked I went into FCP using the DV easy setup and ETT the program sequence and it went to tape with correct TC. Perhaps this could work for you.

To get what you want without outputting to tape I had to go into AE. All the QT settings just duplicated 1 frame in 5. So I rendered a test image sequence at 23.98. Took that into AE and in render settings I set the field render to lower and the 3:2 to WWSSW which is the standard cadence and the frame rate to 29.97. Output module to QT ProRes 29.97 the interlace box made no difference. Then rendered. That generated a true interlaced 3:2.

Compressor adds 3:2 automatically. Duplicate the mpeg2 setting that you want to use. Set the Format to NTSC, the frame rate to 29.97 (you’ll notice that 23.98 is an option), set the aspect to what you want. For field dominance leave it on auto.

Also are you sure you’re not monitoring the deck via the composite super?

Couple of reasons why I prefer using the coordinates. Scaling to my eyes generates a softer image. It could be just me being nuts. Not out of the realm.
The other is the aspect ratio distortion over corrects. I tested this using a native 864×480 image generated in AE rendered anamorphic and straight. I used the straight render as my control and compared scaling and the coordinate shift to the control. The coordinate shift matched the control exactly. The scaled clip was over stretched.

Mistake on my part Upper Right is positive 432 no negative.
-
If you want to remove the squeeze without scaling the video do the following:
Open the anamorphic clip into viewer. Open the distort settings and set them as follows
Upper left -432, 240
Upper Right -432. 240
Lower Right 432, 240
Lower Left -432, 240Aspect Ratio 0
This assumes 720×240 if the footage is D1 the vertical is 243.
