Chapter 7, Using RT.X100 Xtreme with Video for Windows Programs
Selecting your capture format and resolution
1 Choose your program’s Video Format command. The Matrox Capture
Format Settings
dialog box appears:
2 From the Capture Format list, select the format you want for your captured
clips. To create an RT.X100-compatible .avi file, select DV/DVCAM
.
¦NoteIn some Video for Windows programs, if you select RGB or YUV as
your capture format, you’ll have to choose a compressor from the list supplied
by your program. For details, see your program’s documentation.
3 If you select RGB as your capture format, you can select a different
resolution from the
Capture Resolution list.
¦NoteThe only Capture Resolution available for the YUV and
DV/DVCAM capture formats is full-screen (that is, 720×480 for NTSC and
720×576 for PAL). Some Video for Windows programs, however, may only
allow certain resolutions for proper usage, or may set a default resolution that
overrides the selected capture resolution.
¥Tip If you’re experiencing dropped frames during your captures, you can
disable the program’s live video window on your computer monitor (if allowed
by the program) to try to solve this problem. If you have an NTSC or PAL video
monitor connected to your system, you’ll still be able to monitor your captures.
Refer to your program’s documentation for information on disabling the live
video window.
