Q: Pixel Output Problem: Computer < >TV

Soniclight wrote on 9/20/2006, 12:25 PM
I have recently set up my digital camcorder to act as a to-TV play-through bridge with Firewire so I can periodically check on how I am doing in terms of eventual TV output. I'm using NTFS but not HD in or out and I am still not sure whether to go 720x480 with a letterbox crop to 16:9 it, or work in a higher resolution.

I know that standard TV is non-square pixel but confused about what to set the project to, and that TV format is much is lesser "bandwidth." All I know is that pre/viewing it on the TV looks bad. Allow me to be more specific:

For example, I have subtle effects such as sparkles/stars coming through a window (like faerie dust, if you will). For now, I'm creating these effects manually via alpha stills in which star or dust particles are usually only 1 pixel in size. Then I use pan/crop, 3D Alpha, etc. to animate them in layers.

But at some point I will be using a 3D particle generator such as ParticleIllusion -- in which things will be that more subtle. But as of now, this is what happens:

A) OK: In Vegas and/or rendered and watched on computer it looks as intended, i.e. a round "star point" looks round and with feathered subtleties, etc.

B) Not-OK: Viewed on TV screen, they turn to boxy pixels and even rectangular ones = the subtleties are gone and it looks more like tiny Pez candy in flight than faerie dust :)

______________________

>>> Q-1: Will it look like that in final render and prepared for TV viewing also, or is there a way to preserve what I create to look as I wish it to on TV also?

>>> Q-2: If so, what should I keep in mind and set (File and/or Media Properties, etc.) so this can be avoided and/or minimized? I.e. If I stick to 720x, should it be 720x480 DV or 720x786 Standard?

>>> Q-3: Since I will also have to make a DVD version eventually, what elements of answers to Q-2 would be best for the most broad output compatibility (i.e. TV and DVD)?

Feel free to be specific but not uber-techie. I'm still on a learning curve and the more I learn in a way I can understand, the better :)

Thanks.

On your preview window you have a quality setting, what is this set for?

Well, I'm not working in Vegas right now. I usually use Preview Auto or Full unless it gets choppy. Not that I don't have power or memory (Pentium D + 2 Gb DDRM2 + 2 extra pagefiles). I just rather allocate the system more to editing than preview.

Would using Good or Best help solve this in terms of what I would see on the Firewire-to-TV output?

Best might help a tiny bit, but not much. On the other hand, if you have it set for Auto and your preview window is less than full size, that reduces the resolution of the output on the TV as well. If your preview window is, say, 360x240, then your TV display is also half-resolution.

OK, thanks.
