Let me get back to the Flash TV commercial question, even though it is a bit old. Basically, anything that you can get to a video format, you can turn it into broadcast product. And with Flash you can turn your Flash animation into avi, quicktime movie, or eps, ai (adobe illustrator), jpg, or bmp sequence file. I would personally recommend you use the image sequence files. Export the sequence images from flash and import them back to some video editing program, like adobe after effects or ulead media studio pro. Then you can add sound effects or other kool blending effects from the video editing or integration programs. After that you have to prepare the completed video file for the broadcast TV company. Ask them in what format they would prefer it. It is better to not compress the digital video file to preserve as much quality as you want. So the total file size might get huge. So if the television company wants them in a digital format, you may have to hand over the uncompressed video file in a large hard disk of several gigabytes of data. Or you can find some conversion studio and convert the digital avi video file into Beta Cassate format. Many Television companies still accept only beta cassates. And they work with the beta format themselves.
Now the resolution part. For NTSC (US video standard), 720x486 is a good resolution. So if you make image sequences from flash, you have to render it in that resolution with preferably 150 dpi(i am not sure about that). 32bit color of course. The PAL format used in Bangladesh and many Asian or Europian countries has 720 by 576 resolution standard. So that's the resolution you should use for your document size and render the video and image files in.
Hope that helps. I will post more information on Flash for TV commercials and Broadcast quality video if I come across anything new.
