DV playback on PC - out of focus when panning

[dastott]

Dear all,

I have a problem which I hope you can help with. I am now making my 5th full length travel DVD (home movie) and this is the first time I have encountered an "out of focus" problem when panning. This problem is only noticeable on my PC - it doesn't exist when I play back the mini DV footage on the camera.

I am using a new desktop PC to make the movie and this is the first time I have tried doing it on this PC. I'm using DVIO to capture and Pinnacle Studio 9.0 to edit. The PC is Windows XP Pro SP2, 3gig RAM, Pentium 4 3ghz and GeForce 6000 graphics card. The monitor is 19inch TFT. When I play the captured footage in raw .avi format back on the PC the out of focus problem persists. I have played with the monitor display resolution settings, just in case, but this hasn't fixed the problem. Is it the graphics card? Do I have a driver problem? Does DVIO not like XP SP2? I have noticed that in device manager I have something called Legacy Video Capture Devices (WDM Video For Windows Capture Driver (Win32)) which I didn't use to capture as DVIO has always worked perfectly.

My other attempts at making such DVDs have been on an old Pentium 3 700mhz, 192mbs RAM, Windows 2000 (although it took an eternity) and more recently on a more powerful Pentium 4 2.8ghz, 1000mbs RAM, Windows XP Home SP1A machine with the same software (DVIO and Pinnacle Studio 9.0). On these two PCs I encountered no such problems...

Thanks for any help...

Sounds like normal PC monitor problem* with display of interlace sources. This is normal and won't show up in the final dvd displayed to a TV. Make a test DVD. You will see there is no problem.

*You are simultaneously seeing two interlaced fields separated in time by 1/60 sec. When motion happens you see the motion separate the two fields. This is normal and what you want for a camcorder source.

Thanks a lot edDV. You have set my mind at ease...

I will make a quick VCD of the out of focus parts to check that before I throw myself into a project that will take weeks...

Make a DVD for interlace test, not a VCD.

VCD is only 352x 240 and progressive (one field is tossed). This results in a more jerky pan as motion resolution is reduced from 59.94 to 29.97 time sample increments per second.

OK. Is SVCD OK? I just don't want to waste a DVD disc...

Yes, SVCD is OK as far as interlaced fields are concerned.
