Issues with 16:9 and Magic Bullet in Compressor
Hello Chaps,
I’m having a bit of trouble doing some exporting with Compressor.
I have a sequence which is using lots of Magic Bullet editors which is causing ABSURDLY long render times (I read somewhere that compressor re-renders everything… which is causing my problems). The few sites I’ve checked mentioned to export as quicktimee reference and then to encode in Compressor. Fine. Fair game.
Problem is — my sequence is in 16:9 and as we all know when you export from FCP to a quicktime reference movie it always exports in 4:3 (for some stupid reason).
In the past I’ve just changed the frame size to 843×480 as Apple says to do in one techsupport document regarding iDVD + widescreen. The problem with this is that when I went ahead and compressed a file of mine the result was an iPod ready version cropped to 640×304 — losing a great deal of picture.
So I thought perhaps it was just some strange issue because of the 853. I switched my settings to 720×405… and again the same issue — its going to export at 640×304. I’ve gone ahead and just changed the setting myself to the 16:9 aspect ratio so that it SHOULD export at 640×360
I guess my question is – what is the best way around this? Is there an easier way to just do this all in one go? Am I not setting the frame size correctly in QT? Is compressor actually re-rendering all my frames? Can I set it not to?
I really don’t want to have to go through this process every time… so if anyone could help that’d be lovely!

[Adam Schoales] “compressor re-renders everything.”
Yes Compressor re-render everything and if you use a “Two Passes” precess (like for a MPG20 is re-render twice.[Adam Schoales] “6:9 and as we all know when you export from FCP to a quicktime reference movie it always exports in 4:3 (for some stupid reason).

QT do nothing wrong. Only DISPLAYS everything as “Square pixels”. If you tell QT to display as NTSC Anamorphic, will do it properly.
Is just a matter of interpretation of the pixels. If you bring back your 16×9 NTSC clip to FC, probably FC will display it wrong too. You need to check “Anamorphic” in the browser column.
So you only needs that the application that is reading the clip knows if is 4×3 or 16×9, because in both cases the clips are 720×480.Mac OX 10.5.2-FC 6.02-QT 7.4.1

..and always a big mess on top of the table. -
Looks like i solved the problem myself.
All I had to do was export the file as QT Reference Movie — not touch the dimensions, bring it into compressor and it would read it as being actually 16:9 and do it’s thing.
So no need to panic.
