Is it possible that your machine/video/disk is not up to the task? What is your configuration, hardware wise?
It should be a good system:
It is a HP computer.
Intel Quad Q8300 2.5 GHz
4 GB RAM
ATI Radeon HD 4650 graphics card
Firewire card is Deltaco SX-147
I agree, that should not be a problem from a CPU or video card point-of-view. But what driver version do you use and what is your disk setup?
Hard disk is a 640 GB, 7200 RPM, SATA.
According to HP all drivers are up to date. It is a new computer.
Do you think this is a hardware related problem? Or do you think it is some kind of settings that I might change? Like vertical sync or something (just guesing)?
If this is all:
Hard disk is a 640 GB, 7200 RPM, SATA.
you do not meet minimum requirements, which is at least a DEDICATED 7200 RPM disk. I'm not saying that will solve your issue, but at least it will help and even better would be to add two disks to your system. Next check the site of the video card manufacturer for updated drivers. HP is never very fast with driver updates.
You have the 9.09 version when 10.2 is available. Update and it may help.
Unfortunately it did not help. The "flicker" is best sceen when the camera was moved sideways, or something moved across the screen. When the image is relatively still, this flicker is not sceen.
I don't think it is related to the hard disk. Becouse I can see it during playback from the camera allways, not only when reccoring.
You are starting to get me confused.
First you said:
Playback of the captured avi file is perfect, both from VirtualDub and Premiere.
Becouse I can see it during playback from the camera allways, not only when reccoring.
(where I assume 'reccoring' means capturing).
How does it display on a properly calibrated external monitor? The source and preview monitors are just for previewing, not for Quality Control.
To be more precise (this is difficult to explain in english for me):
1) Connect the camera
2) press F5 to get the Capture window
3) I press play button to start viewing whats on the tape in the camera. The video image is now "flickering" of "interlaced".
4) press G to start reccoring. The video images is still flickering/interlaced
5) press Escape
6) save the clip
7) drag the clip to the time line
8) replay the very same clip from the timeline, video images is now perfect with no trace of flickering/interlaced.
So it is actually saved allright into the computer. There is nothing wrong with the avi-file. It is just how it looks during capture.
I also tryed to view whats on the tape on the campera in another program called PowerDirector (a program that was pre installed in the coomputer). The video image is perfect in PowerDirector. I also checked the camera in my old computer, also perfect there.Then I tested Adobe OnLocation to see if I could get something similar there. But no, video image also perfect in OnLocation. I alse verifyed that I had set my project to PAL 25 fps 4:3, the same as the camera.
This problem is _only_ in Adobe Premere CS4 (windows 7 64bit) and _only_ in the capture window.
(I also tryed to change the driver for the firevire card. There are 3 built in drivers It didn't help.)
In Device Manager, select the OHCI device and change the driver to the one that has "Legacy" in the description.
On my system there is 3 drivers to choose from. I have tested them all (with reboot of computer). I can see no diffrence when using diffrent drivers. All works just as good (bad).
I'v got another firewire card in onther computer. I will try that tomorrow...
I switched firewire card. That did not help. Just to be sure I also tried the new firewire card from the new computer in the old computer. It works fine in the old one. So I don't think it has something to do with the card.
I think it is a problem specific to adobe premiere, or configuration related to premiere.
Let's think now: What is it with viewing/capturing video from the DV cam in Premiere CS4 that is diffrent from playing it afterwards from the avi-file when it has been captured? What is it that is diffrent between capturing i Premere compared to VirtualDub or PowerDirector on windows 7, or Premiere CS2 on windows XP?
