remarks
for matrox rt.x10, you must select a non-rt preset, such as sony dsr-45 ntsc (non-rt).
if a preset is not available for your dv-1394 device, you will need to do a test export to obtain the correct values. once you've got the right values, type the name of your device in the preset box and click the save button.
your settings will be saved in the preset list for future use.
3 under offset times for recording, specify the appropriate values for your dv-1394 device.
the first value delays the playback of your project to allow your dv-1394 device time to start recording. for example, some devices require a delay between the time they receive the record command and the time the project starts playing back from your computer.
the second value lets you specify when the command to stop recording should be sent to your dv-1394 device. for example, if your dv deck takes time to stop recording, the stop command must be sent before the end of the project is reached. alternately, if your deck buffers video prior to recording, the stop command must be sent late.
the values under offset times for recording are interdependent. before changing these settings, you should first do a test export to tape with both values set to zero. if you're missing frames from the start of your project, specify a delay for the project playback and do another test. once you've set the correct delay to obtain frame accuracy at the start of the recording, you can adjust the other setting as needed to obtain frame accuracy at the end of the recording.
4 if the in point at which the recording starts on your tape doesn't match the mark in point you specified for the export, use the value under in point adjustment to correct it. for example, if you set your mark in point to 1:00:20:10 and your deck actually started recording at 1:00:20:12, then you would enter -2.
5 if you have an ntsc system, select the format that matches the time code format on your dv tape.
6 click ok to save your settings and return to the matrox dv export to tape dialog box.
