Chapter 5, Defining Your Adobe Premiere Settings

Things you need to know about using DV-1394

devices

Please keep the following points in mind when using a DV-1394 device with

Matrox RT.X100 Xtreme to capture or record DV material in Adobe Premiere:

• Set your camcorder to either Camera Mode (to capture live video), or VTR

Mode (to capture from tape or record material onto DV tape).

¥Tip When in Camera Mode, make sure that the cassette compartment is

empty to avoid possible auto-shutdown of the camera.

• Captured DV audio is sampled at a rate of 48 kHz, 16-bits/sample. Any

audio recorded at a lower sampling rate or bit depth will be resampled to

these values. For the best results, it’s recommended that both your camcorder

and DV deck be able to support 16-bit, 48 kHz audio.

• To use DV-1394 device control, your DV tapes must contain continuous and

consecutive time code, and all material on the tape must be recorded at the

same speed. Leaving blank gaps between recorded material results in

discontinuous time code. To avoid this problem, stripe your entire tape with

time code before recording your source material (see “Preparing your tapes

for recording” on page 71). The existing time code will be used when you

shoot your footage and any gaps between sections of recorded material will

have continuous time code.

• When performing an export to tape, the format you are recording must match

the format on your DV tape. 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.

• The DV-1394 device control requires about six seconds of preroll before

capturing material. Therefore, don’t record material that you want to capture

within the first six seconds of your DV tape.

• When using DV-1394 device control, the running time code display in

Adobe Premiere may temporarily stop. This has no effect on your captured

clips. When the display resumes, the correct time code will be displayed.

• When performing a batch capture, you’ll see video in the preview window

while the clips are being captured, but not while Adobe Premiere searches

for each clip’s In point. If you’ve connected the analog output from your

DV-1394 device to an NTSC or PAL video monitor, you’ll see the video

being played on your video monitor. You may want to use the toggle

switches on your video monitor to switch between viewing the output from

your DV-1394 device and the output from the RT.X100 Xtreme breakout

cable.
