4:3 / 16:9 / DVD / Looping question from CC virgin
this is my first CC posting so bear with me…
i have a job to do by next week for a client who wants to project a 1 minute animation looped onto a wall. this is the email from their technical people which i’m baffled by:“We will be projecting 16:9 using 4:3 projectors.
This means the resolution will be 1024×768 and the image should fill that resolution.
When projecting we will “tell” the projectors to squeeze the image back to 16:9 proportions -

This is easy stuff, so stop worrying! 🙂
Whoever wrote you the brief doesn’t know a whole lot themselves, but the important thing to remember is that, because you’re using DVD as the playback medium, the projector resolution is irrelevant. Here’s a step-by-step of the whole process:
In AE, use a standard AE Anamorphic Widescreen Preset to create your comp. If you’re in a PAL country, that’s PAL D1/DVD 720×576 Widescreen. If NTSC use NTSC DV Widescreen 720×480.
Render to an Animation (100%) Quicktime file.
I don’t use iDVD, but this is easy to do in DVD Studio Pro. Start by encoding your Quicktime file in Compressor – this will save lots of encoding time in the next step. Use the Best Quality 16:9 preset in Compressor. If there’s audio, output that as PCM or AC3 as well.
Create a project in DVDSP. Set the Video Standard (NTSC or PAL). Create a new track (Track 1). (There will be a menu by default – delete it if you want, or just ignore it.)
Set the disc “First Play” setting to Track 1.
Select Track 1 and set the “End Jump” setting to Track 1 (making it loop). Make sure the track is defined as 16:9, and make sure the track is NOT set to “Force 16:9 Letterbox” display.
Import your encoded MPEG2 and audio files. Drag them onto the Track 1 timeline 30 times. This will create a final 30 min DVD that auto plays and loops back on itself.
Save your project, then choose Build & Burn, and insert a blank DVD when prompted.
You’re done!
