Panning stills
I’m working on a commercial with a horizontal pan of kitchens. So that means a lot of vertical lines. When previewing on my broadcast monitor there’s a lot of comb teeth on the vertical items (i.e. table legs, edges of cupboards etc). So far I’ve set my shutter to 360 and used the Reduce Interlace Flicker plugin set to 0.4. The keyframes are linear and position speed is 80.38. On the real vertical items it still looks crap. What’s the best way to eliminate the effect?
AE 6.5.1 pro/25fps PAL

Are your images scaled down? We’ve had this problem at studios and ended up using an actual camera on a track over a picture.
The problem is that if your image is scaled down, then as it moves from left to right or scales up…etc. you are revealing hidden pixels – rmember, a 50% scale image has to put half it’s pixels somewhere – in high contrast areas, this reveling and hiding creates a shimmer.
Some solutions I’ve heard say use frame blending or blur the image a little. Neither of those has really ever worked for me though.
If your image is scaled down, but you aren’t scaling up or down, you might consider actually scaling the image down in photoshop or the like. That would get rid of the hidden pixels.

Thanx Aharon. The image was scaled down to 90%. However, I scaled up to 100% and ran a preview. No change. And frame blending is not supported on stills is it?

Your right their not. I think we may have tried rendering and then playing with time and using frame blanding, but it dodn;t work.
Have you tried rendering with fields (interlacing). That often does the trick (while sometimes creating other problems).
Give that a shot.

I’ve tried rendering a test with fields and import that clip back in AE but then what? Deinterlace?

Aharon, I think I’ve got it. I rendered the pan with fields, reimported that clip and set the field interpretation to off. The preview of this is pretty smooth.

interlacing is what you do for your final render – the one that will be seen on an NTSC monitor. You shouldn’t interlace until your final output. Test that rendered interlaced video on your monitor, but not through AE. – wait, Maybe I’m wrong – you could try and bring it into AE and interpret it as Lower Field First (unless you are interlacing as upper field first). Then put it on your monitor to see it – Your monitor might show it the way it should look. Give it a shot. If it looks good, then you know that interlacing is the way to go for your final render.
Don’t be surprised when you import your interlaced footage – Interlaced footage brought into AE usually looks bad in the comp window, even when interpreted correctly – it is literally half of every frame missing (every other row of pixels is hidden). It should, however, look OK on your monitor, provided you don’t take the interlaced footage and scale it or move it from it’s original (centered) position.
I don’t want to make you run in circles here. Interlacing issues are one of this things I try to avoid at all costs. Too many variables, and without seein it myself, these are just guesses.

That’s weird – interlaced footage in AE rarely looks right. Especially when not interpreted properly. Make sure that you are not getting scan lines showing blurred frames (as if you were seeing more than one frame at a time).
But hey – if it’s going to your TV correctly, then that’s what works. But make sure it plays well outside your Computer set up -put it on tape and see how it looks.
I hate interlacing…
