Converting to HD
Hi. I work on an animated TV show that has been SD. For our second season, we are going to be working in HD. The entire show is done with After Effects, Photoshop and Illustrator. We are going to 1080 size. What kinds of things do I need to know for the switch? Does anyone have a good link to info about the differences I need to know? Pixel aspect ratio? We just found out about this today so I wanted to do some research…

So, a standard def picture is 72dpi. What is the dpi for an HD picture? Or is that even applicable? Is HD at 300dpi? I guess I am asking, if we are making a background in Photoshop, should it be 72 dpi? The Photoshop preset for HDTV is 1920 x 1080 at 72 dpi.

What flavor of 1080 HD are you going to be using? Sony? Panasonic? What gear do you have now? Is it full HD or HDV?
Mr. LaRonde is right in saying to expect all that he said but the type of HD will effect storage and the gear you’ll need to work with it. The 1920×1080 preset in PS and AI should work for any 1080 HD or HDV just fit the file to you Comp in AE.

There is no gear. It is animation, so everything is created in either Photoshop or Illustrator, then animated in After Effects. I think I am starting to understand a little better. I think it’s just going to suck, because we’re going to have to do almost all of our backgrounds over again.

Well you’ll have to output at some point.
Anything from AI or any raster graphics can be scaled without a problem. Bitmapped things…yep it’s a do over.

Keep all your art at the same dpi rate. It really doesnt matter for video because a pixel is a pixel, and dpi is moot in video. But it just makes it so that all your vector and pixel art is all at the same “size” in the photoshop/illustrator/after effects world. It means that path and vector data you move between documents will come in at the right size and save you rescaling.
Remember that HD is all 16:9 and SD in the US is generally 4:3 right now. So even though an SD in 16:9 and 4:3 use the same number of pixels, the 16:9 one uses rectangular pixels.
I have an HVX200 and I use a clip from that dragged into After effects to automatically create me a comp with the right pixel size and aspect ratio. I have clips for 1080p, 720p and 480i. I know those clips conform 100% to my delivery codecs because they are recorded in DVCPROHD and the SD clip in DVCPRO50.
So I know my comp will be set to the right settings. -

re read your quote. I don’t see HD 1080 mentioned.
