Bob? Does this answer your question: "BTW, the same effect happens when I use a camcorder via DV for preview." - maybe not?

Anyway, I can't repro. Getting solid 25fps this from a FINISHED rendered project; SD 16x9 PAL - solid as a large mineral outcrop!

Grazie

Actually, StudioB, would you ind asking your question again, in another way? What exactly IS your issue? I should've re-read and asked again THEN!

Cheers,

Grazie

As I don't have 8.0c installed this could be a problem specific to that build.
Aside from that there is a general problem I've noticed previewing HDV out a firewire port as SD from a HD project. The problem is related to interlacing as you only see the problem on motion. What you get are those horrid dogs teeth artifacts on vertical edges.

From SD 16:9 or 4:3 DV material I've not noticed any problems, ever, in any build.

Bob.

o.k. - here we go again:
I am editing SD interlaced material in PAL and I am using the ADVC-300 for external preview on my CRT monitor.
Preview is stable but motion is not reproduced correctly when the deinterlace method setting in project options is set to "none".
The wrong field order - at least for me it looks like this - only disappears when the following two conditions are met:
1) Set DeInterlace method to "Blend fields" or "Interpolate fields"
2) Set Preview quality to Good (Full) or Best (Full)
All other settings of these parameters produce interlace artefacts on the CRT

Item #1 sounds strange to me as I do not want to and don't need to deinterlace in my setup. BTW, it took some time to find out about that...

I hope that things are more clear now.

TIA
Boris

I use ADVC 300 quite a bit to output to SD monitor, no problemo with interlace artifacts from SD material.

#1 would only be required if the footage is being rescaled. Rescaling requires the two fields to be merged prior to scaling and then split again into fields. With no method specified wierd artifacts do indeed appear.

However you should not be doing any scaling. Which project template are you using?
Is it PAL DV or PAL Standard, the latter is wrong for DV.

Bob.

Thank you Bob for taking time for my problem.
The video is not scaled and the template is PAL DV. I tried another DV converter (Canopus ACEDVio) with the same result.
As an alternative way I tried using the secondary display output of the graphics card but I did not manage to get a clean interlace output neither with my old Matrox G550 nor with an ATI Radeon X1250.
Both cards will play DVDs with interlace material fine on the secondary output so maybe Vegas has a problem with outputting interlace material in preview mode.
If you would like to check my source material I could send you a short clip : I am using a special pendulum clip which is designed for checking interlace problems.
