when editing on matrox rt.x100, you can choose to work with source video that's been recorded in either the 4:3 standard tv screen format, or the widescreen 16:9 format.

to create a production in 16:9 format on matrox rt.x100, do the following:
1 record your video onto tape with your camera set to the widescreen 16:9 format. the video will be recorded as horizontally compressed 4:3 video.
2 start adobe premiere, then set your editing aspect ratio to 16:9 as explained in the section "selecting your editing aspect ratio" on page 41. this ensures that the effects you create on matrox rt.x100 will be displayed with the correct proportions when viewed in 16:9 format.
when editing in 16:9 format, certain pre-created matrox organic wipe or mask patterns may appear distorted. for example, circular wipes will appear elongated.
3 capture your video clips as you normally would. select the 16:9 display option on your ntsc or pal video monitor to "unsquish" the video and play it back in widescreen format without distortion.
4 if you create animations, titles, or graphics (including organic wipe or mask patterns) for your production using a program that lets you set the pixel aspect ratio, use the appropriate setting for 16:9 display:
- on an ntsc system, set the pixel aspect ratio to 1.185.
- on a pal system, set the pixel aspect ratio to 1.422.
if you can't set the pixel aspect ratio, create your image at 853??480 (ntsc) or 1024×576 (pal). after you??ve created your image, resize only its width to 720. when you resize the image, your text or graphic will appear elongated on your computer screen.
5 edit your production as you would a standard 4:3 production. make sure you change the pixel aspect ratio setting for your project to d1/dv ntsc widescreen 16:9 (1.2) or d1/dv pal widescreen 16:9 (1.422), as explained in the section "defining your video settings" on page 47.
be aware that if your video monitor is displaying in 4:3 format, certain effects may appear elongated because of the horizontal scaling. setting your monitor to 16:9 will display the effects with the correct proportions.
6 record your finished production onto tape. remember that you'll need a monitor capable of displaying material in 16:9 format to properly view your master tape.
