Hey,
iv just finished a 10 minute movie iv been working on. its all recorded and edited in 1080i HDV.
Iv made a DVD copy of it and exported back to tape, but i want an HD digital version for various reason. Iv done a few test Encodes and have been hitting the 300mb for 30 SECONDS! On apples trailer page they seem to be able to get 2 minutes down to about 160mb whilst retaining full 1080i I would like to know how to replicate these results. Anyone know what specific settings they use. or any that you know of that seem to work pretty well. Im using compressor.
cheers

In theory (based on the numbers given) it would be h.264 codec at around 10mbit/s

yeah use the H264 Codec, compress' very nicely

The AppleTV preset is pretty good.

Ahh, you want to keep it at 1080. Fair enough :)

Though (I could be wrong), I thought 1080i was the same as 720p?

1080i is 1920x1080 interlaced
720p is 1280x720 progressive

In answer to a point that was made earlier.
The trailers on apples Web site are compressed via doing upto a dozen passes on the file. They use a hardware compression unit as can you imagine if they used compressor how laborious the task would be. That's how they get the low file sizes and the fantastic quality.
Take a look at there new itunes high def tv shows, never more evident than there.
So point is you wont get a super high quality encode in comparison to apples encodes.
So a higher bitrate will be needed to compensate.
Also always deinterlace 1080i material. This also helps with file sizes and helps to remove interlace jaggies and generally smooth out your picture.
