Yes, but that version of COmpressor won’t have the necessary AppleTV preset, and you are also working in HD so an HD preset won’t work.

Instead make a 640×480 29.97 h264 with aforementioned audio specs.

OK, so in FCP – export as:

640×480 29.97 h264
AAC @ 160kbps, stereo

then bring it into Compressor and export it as Apple TV?

Make the project 720p to make things easy (DVCPRO HD is probably optimal in FCP5), and render to this size in H.264.

For the love of God, don’t use DVCPRO NTSC (DV).

DV has 4:1:1 color sampling, meaning 75% of the color is discarded, and the resolution sucks.

Technically the Pad is 1024×768 with square pixels, but it does an amazing job showing 720p (1280×720).

I would not recommend this, and keep your video 4×3 SD.

Also, this size doesn’t work, I’ve tried. It wants 720p video (for HD).

No, export your movie out of FCP.

Export > Quicktime Movie > leave self contained and recompress all frames UNchecked (this exports a reference movie).

Then in Compressor make an h264 preset @ 640×480, deinterlacing on, and AAC audio @ 160kbps.

Different things:

1. The iPad’s screen is 1024×768.

2. The iPad can play back 720p files on its own screen, scaling it to 1024×576 with black bars on the top and bottom, or it can show them in full glory on an external 720p+ screen.

iTunes uses 960×540 if you use Advanced>Create iPad or Apple TV version.

Low res video looks a lot better on an iPad than on a desktop or laptop computer, but with stills the OP may be pushing her luck for what she wants to do.

DVCPRO50 would be the best choice for SD as it is at least 4:2:2, which will end up as 4:2:0 in the common profiles of H.264, and it can be either 4:3 or anamorphic 16:9.

Regular DVCPRO (DV25) is 4:1:1, which will end up being 4:1:0 when rendered to H.264 for iPad, so only 12.5% of the original color information will remain. There may be some chroma smoothing to ameliorate the result, but why cripple nice photos?

4:3 or 16:9 is a matter of what is the most common aspect ratio for the photos.

BJ, we will agree to disagree with some of your facts.

First, the original poster needs to get her job done.

OK, So I’m a little stumped.
I thought it would be better to make the overall size of the movie larger so the quality will hold up full screen on the ipad.

The setting options in the sequence preset editor are:

frame size: I am trying to make the video 1280 x 720 so used the custom option and typed this in

pixel aspect ratio: the only options are:
NTSC – CCIR 601 / DV – 720 x 480
PAL – CCIR 601 – 720 x 576
HD – 960 x 720
HD – 1280 x 1180
HD – 1440 x 1080

Editing Timebase: 29.97
Compressor: h.264

Since the pixel aspect ratio does not match my frame size, I’m not sure what to do.

Thanks again for all of your help and taking time to help me w/ this!!!

Diane, please try the 640×480 screen size first. See if it works for you.
