Problems interpreting AE motion graphics to a Widescreen TV without pixelation
Hi Everyone!
I don’t know who else to ask so Im seeking the “Creative Cow” for assistance. Currently I am working on a project that I created in After Effects 7.0 using a PC. When Rendering I used the best quality, Quicktime using Animation so no compression. The quality on the quicktime is beautiful. So this must be a progressive/Interlacing issues.
This quicktime file has to be made into a playable looping DVD. The settings are NTSC D1 Widescreen Square Pixel, 864×486, Square PIxels (16:9) frame rate 29.97.
This is playing on a Panasonic Widescreen TV and after seeing it on there…the text is wavey on the bottom..like there are ripples going through them. The rest of the text is crunchy/pixelated looking. The graphic elements contain important jpegs which now look crunchy along the edges (i see moving lines). The other elements are stripes that I made in after effects using masks. They are suppose to be red and on that tv they appear jagged around the egdes and a white line has formed around the entire stripe.
I appreciate anyone taking the time to read my novel here. I’m just torn and not really technically inclined. Any thoughts or suggestions are greatly appreciated!
Thank You!

The issue is not the TV, it’s the DVD. The format restrictions always lie with the playback medium, not the display device.
You need to drag your 864×486 comp into a “DV widescreen preset” comp and render that. Bump the comp up one pixel if you have interlaced footage.

Honestly interlacing shouldn’t be an issue when creating a DVD unless the field dominance of the footage was incorrectly handled at some point. Either the MPEG-2 Encoding should know that it’s dealing with 23.98 footage that should be ‘progressive’ or it knows it’s dealing with 29.97 footage that should be ‘interlaced’ (I use quote marks because everything is interlaced in DVD stream MPEG-2).
It sounds to me like your problems are coming from either:
A) Poor MPEG-2 Compression/incorrect MPEG-2 settings.
B) Incorrect color management.
C) Both.
Are you using AE CS3? Who is doing your compression? How is the DVD being authored?
As I look at your initial post I also think your composition settings may be incorrect, I didn’t realize it at first but it sounds like you’re rendering out of AE with an NTSC D1 Widescreen Square Pixel comp… don’t do that! Use NTSC DV Widescreen (not square pixel)!

Thanks for the input. I’m rerendering as we speak. I am using AE 7.0 not CS3. As I’m watching this rerender though, things are being squished and stretched. For instance, there is this stripe that comes from the left side of the screen and has text written on it. The point is for them to come in together and then the stripe exits the same way it came in. Long story short, the stripe doesnt cover the text anymore, instead it only comes about halfway between what it use to. Is that something I’ll have to fix after I change to NTSC DV Widescreen before rerendering?
As for the MPEG2 Compression: the editor used “Compressor” on the new iMac choosing the high quality settings – which authors the DVD. I’m not sure about the color management side of it.
Thanks again for your time!

Compressor should be fine, I really think it’s the composition settings.
Use Steve’s advice and don’t change the composition settings (since you already have everything laid out), just create a new NTSC DV Widescreen composition and drag your NTSC Widescreen Square Pixel D1 composition into it.
Everything should work out… you’ll have 6 vertical lines cropped but that shouldn’t be a big deal.
