Exporting your sequence to tape
Exporting your sequence to tape
Your Matrox RT.X2 system lets you export your Adobe Premiere Pro sequence to
tape using DV-1394 or RS-422 device control. You can use Matrox DV/HDV
device control to control DV-1394 devices. For RS-422 devices, you can use
Adobe Premiere Pro’s serial device control as explained in your Adobe Premiere
Pro documentation.
Preparing your tapes for recording
To use device control, the tape on which you’ll be recording your material must
contain continuous and consecutive time code. You can stripe your entire tape
with time code by recording black video for the duration of the tape.
¦ Note The format of your DV tape must match the format you’re recording. For
example, if you set your DV-1394 device to record in DV/DVCAM format, your
tape must be striped entirely in DV/DVCAM format. Mixed format tapes are not
supported.
Avoiding missing frames when exporting to DV
tape
When performing an export to tape on some DV-1394 devices, a delay may occur
between the time the device starts recording and the time that Adobe Premiere
Pro starts to play back your project. This may result in the first video frames of
your project not being recorded to tape. To ensure that your export to DV tape
does not miss any frames, you can delay the playback of the project that you are
exporting.
To do this, you will need to do a test export with your DV-1394 device to
determine the number of frames that are missing from the start of your project on
the DV tape. In the Adobe Premiere Pro
Export To Tape dialog box, select
Delay Movie Start and enter the number of frames you’ve determined are
missing from your project multiplied by 4 (to convert the value to quarter
frames). If needed, adjust this amount until you obtain a frame-accurate or near
frame-accurate export to tape.
¦ Note If your exported video is frame-accurate, but you’re missing audio at the
start of your project on the DV tape, simply add a few frames of black and silence
at the start of the sequence. If you do this, you may not need to use the
Delay
Movie Start .
