miroVIDEO DV 200
If you find that recording started or ended inaccurately we recommend that
you use black frames at the beginning and at the end of your video
production to ensure that the total production is recorded.
Note that the export-to-tape accuracy depends on the DV camcorder or
VCR that is used. Pinnacle Systems cannot guarantee that this function is
supported by all DV devices.
We also want to remark that some DV devices activate the analog audio
signal with delay. It can happen that there is silence during the first second.
But the data is put onto the tape properly.
Discrepancies
Suppose that you wanted to start the cut at time code 01:00:00:00. What
was the frame number at the start of the cut after the project was transferred?
If it was at 01:00:00:01 or more, the clip was started too early. Therefore,
you should enter a smaller number of frames under “Pre-roll”. Repeat the test
until you arrive at a satisfactory result.
If the first frame at the start of the cut was black or if you saw repeated
frames, the clip was started too late. In this case, you must set a higher
number of frames for the “Pre-roll”.
Premiere 5.1 and time code
Internally, Adobe Premiere assigns frame numbers to your recorded clips
instead of genuine time codes (this applies to all versions of Adobe
Premiere). Frame numbers are random, automatically incremented numbers
that, above all, facilitate the work of programmers. However, as one and the
same frame number may correspond with one of three different time code
values, depending on the time code format used, problems may be
encountered if the correct time code format is not set. This may be relevant
in the following situations:
s
You manually enter a batch list with the wrong timed code format, or
s
You use Premiere's logging function without device control in the video
recording window (Movie Capture).
s
The time code format in the recording window does not match the current
tape format that is currently being logged.
This may lead to various errors like the following:
s
"Time code not found" error message
s
The time code on your clip is offset by a few seconds
s
Recorded clips begin with a wrong time code
The reason for this is fairly basic. If you choose a time code of 01:00:00:00
for the starting point, Adobe Premiere may interpret this value depending on
the format of the digitized video:
s
NTSC (NDF time code) 108,000 frames
s
NTSC (DF time code) 107,892 frames
s
PAL 90,000 frames
