Thanks for your reply.
>>1) What frame rate is set in the "make Movie options" Premiere tends to use
only 15 fps which of course results in bumby pictures. 30 fps for NTSC (25 for
PAL) should give better quality. <<
I'm using 30fps for everything. The quality of my professional video is very
good, with the exception of the pulsing the I can see in the results I output
to tape.
>>2) Did you set anything in the "data rate" option ? Try to test the data
transfer rate of your system within the MCI-device-Setup. Set the data rate
according to this. A too high rate will make the PC to loose frames when
loading. <<
I've played with the data rate and it does not seem to change my results. The
only time I get the pulsing is when I use the professional video — consumer
Video-8 and VHS do not cause the pulsing.
>>What is a TBC ? <<
Time-based corrector. I can't get real technical on it as I'm more of a
computer techie than a video techie, but it synchronizes the video signals I am
sending from my professional decks to either my edit controller setup or to the
MMPro. I needed it for the MMPro because the video was skewed to the right in
the MMPro without it (from the pro decks, my VHS stuff was ok).
>> What PC-equipement do you use ?<<
I'm using a PCI, Pentium 90 from Gateway 2000. I have 32MB of RAM, 1 GB
Fast-SCSI drive, Adaptec PCI Fast-SCSI controller, and a Diamond Stealth 64 PCI
video board. My sound board is an Ensoniq (Sound Blaster compatible).
>>Does "make movie" need every time several hours to create a movie ?<<
I've experimented with this and it seems (based on a suggestion I received a
couple of days ago) that the time needed to make movie depends heavily on:
– your computer
– whether you are consistent in your settings between capture and make movie,
it seems if the setting are different, it takes longer to create the movie.
– how "clean" your hard drive is
>> when i capture a movie in 160 x 100 there are more lost frames than in 320 x
200. Did this happen to you too ?<<
Sorry, I haven't used anything lower than 320×240.
Hope this helps.
