my semi-transparent banner looks ugly on TV, why?

Not sure if this will help you, but when I render out dvd video in Premiere Pro I always choose to deinterlace the footage.
It stops flickering and the sort of problem you’re describing.

I’m not at the pro-end of things, but it may be that you need to look into field-rendering. In short, you have to double the number of frames per second. There’s some tutorials here on that subject I think.

Hi.. Thanks for the reply. Well, I tried de-interlacing the graphics in Final cut Pro, but it ended up making it extra flickery… I actually experimented with this by burning a dvd with the graphics repeating, and I applied all of final cut pro’s de-flickering, and de-interlacing options.. One after another.. When I viewed it on my dvd player and TV, I saw the 2px banner look identical (and wrong) in every instance, but the text I have over it actually got horribly flickery on the deinterlaced version.. Everything else looked identical.

So… That didn’t seem to be the problem. You mentioned doubling the frame rate.. How would I go about doing this while super-imposing this graphic over video?

Thank you

This problem is almost always a rendering issue…

I always render out of an editing software instead of AE… the quality is much better and the problems like you have are almost non-existent.

Here is a method/approach that you might try…

First, I begin my final render out of Avid Liquid not AE(in AL language that would be to “fuse” not render) to…

…Vdub. That is a VERY good rendering program using the Donald Graft smart deinterlace filter (… perhaps because it has the ability to encode in both a temporal and spacial fashion).

Using Vdub with the Donald Graft smart interlace filter (i.e., filter: smart deinterlace Window) you set as follows: Mark Motion Processing as Frame-only difference and Motion map denoising (motion threshold 15) and Scene change threshold 100… Advanced Processing mark as Phase shift and Field swap after phase shift and disable motion processing. Then encode with TMPG (using 3.0xpress or CCE).

Donald Grafts Smart Deinterlace filter for Vdub:

After you have downloaded both Graft’s Filter and Vdub of course.
In Vdub go to – Video>Filters>Add>Load>(go to folder with Grafts Smart Deinterlace filter)Open Smart.vdf file.

Finally, a general rule I use is this… NEVER check any box that has the work “interpolation” as a choice while rendering.

You might experiment with Vdub for your rendering process… I think you will be plesantly surprised as to the quality improvement in your final video results. There are a lot of encoding/rending options to choose from (not to mention a whole bunch of other rendering/filter combination options)… so, the sky is the limit… which can be a problem in and of itself.

Hope this helps.

The above suggestions may work, but really, this is a good example of why you should be working with a preview monitor. Thin lines and TVs just don’t get along very well – that’s just the nature of the beast, unfortunately.

Also, you realize that your text is outside the safe zone, right? You’ve got the overlay on, but it doesn’t seem like you’re using it…. You need to move your entire lower graphic up so all the text stays inside that inner rectangle.

Hi There… Yes I am aware of the text– I have since repositioned it.

Well here’s the thing: I do have a preview monitor.. It’s a JVC pro monitor specifically for video work. I have a Firewire to DV converter that outputs to RCA, which I have connected to my monitor via bnc.

When viewing on the monitor, the thin lines look great..

It’s actually after they have been rendered exported to DV NTSC, and encoded on a DVD that they no longer look the way they do…

Yeah, I just confirmed this by hooking my dvd player up to my pro monitor… It’s definitely a result of the mpeg2 compression………. Which makes me think that nothing can be done..

I’m not sure, but could it be that DV output? I’ve noticed a similar issue with just about every animation I have put to DV. Just a little soft, no clean edges. Similar problem keying DV.

No solution, just a thought.

As a rule of thumb, I never make solid lines that are less than 3 px tall because anything smaller will tend to flicker once it hits interlacing.

You may be able to lessen the flicker by using a vertical blur of about 3 px

Also, stay away from thin diagonals in DV.
