-20 dB. Meaning the sine wave tone at -20 db. But like Andrew said, every spec I gave you was US.
As a side note don’t be expecting to go from AE to a deck. Drop your files into an NLE like Premeire or FCP. Make sure that you do your RGB to YUV conversion properly though when you do or the levels may shift.

Going to a TV news affiliate for regional broadcast or to a dubbing house to be distributed around? If it’s just to a local TV station, just give them the uncompressed file. I gaurantee you they have a way of outputting the file through their systems.
If you HAVE to do it all yourself ready for broadcast:
Your working resolution should be 720 x 486. .9 pix asp. You can rent digidecks for a few hundred a day. (that’s what we do). Get a cheap uncompressed card like a Decklink. Generally you output SDI to the Digideck.
But there are many other factors like the VITC and LTC TC should match, Spots should always start on exactly 01:00:00:00. Then each spot exactly one minute after. So the second spot would be 01:01:00:00, etc.
Need bars and tone at -20. at the head. then slates. Usually there are ISCI codes involved as well.
But as a general rule, just ask those that need your stuff what specs they want. Then there’s your answer. But honestly, unless you feel like becoming a “Post House”. Don’t bother. Just put your spots in an uncompressed Quicktime file at D1 settings and have someone else do all the broadcast standards stuff.

Sorry, not familiar with Lightwave. Just Maya and C4D. I played with lightwave once a loooong time ago when it was part of the Video Toaster.

You could use the alpha channel as the 4th channel. If you can get your 3d program to write data to that channel that is not transparency. Then when you import it to AE make sure the alpha channel option is set to ‘none’.
However it seems like a real bear to do. I would just deal with the 3 channels at a time.
Or you can look at Open EXR which has generally unlimited channels. AE 7 now uses Open EXR, but I’m very unfamiliar with how to implement all the channels in AE. In Nuke for example it sees Open EXR very similar to a multi track audio tape. It allows you to split the tracks and do with them what you please. This way you can keep many, many passes from 3D all self contained in one file.

If it’s what I think it is, have them re-render it properly with the 3 primaries plus black. I take it it’s a 3D pass to get 3 channels of data in one render. Like a normal map, or a lighting map.

Nice city:
2 notes:
1. Instead of a curved surface for your BG you could use the old fashined “Pan and Tile” method used in feature films. They’ve used Nuke to do this all through the 90’s for BG’s in movies. It can just as easily be done in AE 3D space. Here is a demo of it (see link). They show it in Maya, but it applies to AE. It’s also generally how they do the environments in video games. With a cube instead of a sphere:

2. If you own Cinema 4D, there is a free plug in called “City Gen” that creates a city like yours automatically. You can set how big the city is, the maximum heights. The ratio of building types (skyscrapers to regular buildings to low buildings etc.) It even generates the streets and park areas. Texture mapping is really easy because for each “type” of structure it gives you up to 8 (i think) material drop boxes. It will randomly pick from one of the ones you dropped in to apply to the structure. So if you made 6 skyscraper texture maps, you will get 6 randomly assigned looking sky scrapers. This applies to all the other building types. You can build massive cities in no time.

As far as AE, Keylight (free w/AE) is one of the best keyers in the world so if it’s lit right you should be able to key it. I have the Chris Cunningham DVD and I think in the commentary he said they were just shot in water with only the subject lit so the rest is black. Then it is probably SCreen transfered onto the dark BG (Street scene). So there may not be keyeing at all.
Might want to pick up the DVD and listen to the commentary.

If you get the CC “Environment” I mentioned in the post above, it perfectly locks to the AE camera. SO whereever you pan the camera, it is true.

Cycore makes a plug-in called “Environment” it is a virtual sphere that you can map BG maps onto. It matches to the AE cam.
Also if you just want to bend it, there is a plug in called “Freeform” to do minimal bending deformations.
