Box Effect on Kalypso

I'm hoping to get a few tips on building an effect that I've seen used a lot (NBA, I think), but I've never built it myself. It's probably pretty simple to most of you. My source will start full, then push back to a box, with graphics above it and to the left of it. I've been doing this the old school way - with graphics stationary and the video reveals them as it pushes back. I want everything to push back together, so that when the source video is full, the graphics are sitting outside of the frame, then move with the box. What's the best way to make sure that when the box is full it matches the same source straight, without the TE attached? Do you build the effects with graphics and video separately, then run them together?

I'm not going to have a whole lot of time to build this, so I'm just trying to get a little head start.

Thanks for any suggestions you might have...

I was thinking of combining just the BG and graphics on a SEC M/E, the video would be on a separate TE on the PRI M/E. Would it be better to start with video full and graphics blown up outside the frame, then build from there? Thanks for your replies... even reading your questions helps me figure out how to even think about it!

[quote="Steve Meyer"]Bob, could you shrink & position the video in Loc XYZ 3D space, then use negatives of the individual channel's value on the global channel?[/quote] If you're only shrinking the live video (let's say to -100), and leaving the GFX & BKG Loop alone (so they stay at 0, then inverting the live video numbers (to +100) & applying it to everything won't look right - the video will OK but the background channels will be wildly large. Also, because the video & background channels will be at different positions in 3D space, applying a single Z change to all channels will produce different reactions. That's why I suggested manipulating the overall size change for the 3 channels in LOC SIZE - the 2D space won't care about the 3D positions & everything should move together as 1 unit. Remember that if you pre-combine the 3 sources on another M/E - using either Double-Take or the Programmable Clean Feed, the the live video will be 1/2 size or smaller...blowing that up downsteam to a full-size picture will trash the video.

The only way to combine is to use layered mode in a different ME and then re-enter into your air ME. This assumes you have Double Take. You have to remember, this type of stuff wasn't being done when the box was designed. As Bob has posted before " A switcher should always be "smarter" than the operator - it should always have more "headroom" than what is currently needed to do what the TD wants so that the TD always has room to grow their own capabilities. " Things you would have seen only on a network show are considered common now.

Also, is there a way to combine the TE channels into one keyer? I'll actually have three sources - video, graphics, background loop.

Pre-shrinking the box & then blowing everything up as a single unit can result in trashing the video. If you shrink & position the box in Loc XYZ (3D space), now manipulating both the (previously unmanipulated) CG and the box using 2D space (Loc Size) should make both the box & the CG background move together. Unless you use absolute integers on the Loc XYZ side, it may be tough to type in numbers into the 2D element compensate for the size & position change - you may have to resort to cutting between the original source & your effect in order to fudge the box to the correct full-screen size.
