aspect ratio of HD
I recently bought a Western Digital device for $100 from B&H that takes anything on a USB 2.0 hard drive and you can play it on a TV, either through HDMI or anolog output from the WD. I had a FCP timeline on my G5 which was HDV, 1440 x 1080i. I exported it using Quicktime Conversion, using the audio Little Endien codec, 48kHz, at the size of 1440 x 1080i. On the Apple Quicktime Pro on my editing machine, it played in proper widescreen. On my other smaller Apple G4, if I put it to View, half the size, it still had a wide screen aspect ratio. However, when I used the HDMI interface from the WD into the Plasma TV, high definition, it was squished and I could not hear the audio. So then I used QT Pro on the G4 and exported from the previous export from the G5 (I used an external HD between the two) to 1920 x 1080 and also converted the audio to AAC, 48kHz. Looks fine on the Plasma TV and the audio is fine. First question: What might be the best setting to do what I am trying to do from the first FCP timeline on G5? Second question: Why did it look Okay on my Macs, but not on my TV? Third question: When I recompressed on the G4, did it really recompress the pixels or just pass them through and put some kind of flag on them? They look about the same as the squished version only spread out properly. Thank you in advance.

HDV is an anamorphic codec. Basically meaning that it is stretched out on playback to a 16:9 aspect. 1440×1080 is not 16:9, but 4:3. On export, go into the video settings and change the size from 1440×1080 to 1920×1080. Also, change the audio compression settings to AAC 48KHz. All of this can be done by clicking the Settings button in the Export QuickTime Conversion dialog.
