Audio Drift Detection

What is Audio Capture Drift Detection?

The first time you try to perform an analog capture in Adobe Premiere Pro, you're prompted to run the Audio Capture Drift Detection test. This test ensures proper audio and video synchronization between your sound card and your Matrox RT.X hardware during analog captures, and must be run prior to performing an analog capture. Click Start to run the test, or Cancel to return to Premiere Pro. If you click Cancel, you won't be able to perform analog captures in Premiere Pro until you run the test.

Note This test is not required for DV-1394 capture.

Once you've completed the test, you won't be prompted to run the test again unless you replace your sound card. You can, however, start the test manually to run it again. If you update or re-install the drivers for your sound card, or move your sound card to another slot, you should run the Audio Capture Drift Detection test again.

To run the Audio Capture Drift Detection test:

1	Choose Start > Programs > Matrox X.tools > Audio Capture Drift Detection.
2	From the Test Duration list, select a duration for the test. In most cases, five minutes will give you good results.
	Note If you often perform long analog captures (longer than one hour), it's recommended that you select one of the longer test durations from the Test Duration list (such as, 10 minutes).
3	Click Start to run the test.
