Chapter 8, Using Matrox MediaTools
Grabbing a single-frame image
You can grab single-frame (still) images and save them as .tga or .avi files to use
in your Adobe Premiere projects. Your source video can be a clip on tape, a clip
on disk, or live video.
¦NoteIf you save your image as an .avi file, it will be saved in
DV/DVCAM format.
°To grab a single-frame image:
1 If your source video is on tape or disk, use the transport controls to play back
your DV tape, or double-click a captured clip in the clip list to play it back.
2 In the MediaTools dialog box, click the Grab Image button to open the
Grab Image dialog box. Drag the Grab Image dialog box to the side so that
it doesn’t obscure the
Preview Window.
3 From the AVI/TGA Selection list, select Single-frame AVI or TGA to save
your image as an .avi or .tga file.
4 When the frame you want is displayed in the Preview Window, click the
Grab button.
5 If you notice flickering in your image, you can choose to grab only one of
the fields. From the
Grab list, select Field 1 or Field 2. One field contains
the odd-numbered scan lines in the frame, and the other field contains the
even-numbered lines. Select the field that best displays your image.
MediaTools interpolates between the two consecutive scan lines to create the
missing field.
6 Click Save or Save As to save the image.
