I have a AVCHD camcorder and record at 1080. After editing in iMovie what setting should I use if I want to play the video back on a Mac hooked up to a HD projector? I was thinking H.264 with the compressor set to high (not highest) to keep the files around 17Mbps then also create one using the AppleTV export incase I ever went that route. HD takes forever to encode so I want to get some advice from someone who's tried it. Also, should I use the same settings for SD video? Thanks.
