    I had 2 identical cameras but one was set to 1080i & the other DV widescreen. What should the project template be? The lower common denominator or higher? I tried using 1080i, but when I render and make DVD in DVD5b, I get this weird watery motion artefact on anything vertical that is moving. Reducing render quality to good helps, but I still get a noticeable strobing effect, like a flash is going off

    I’m afraid you’ll need to use the lesser of the two and stick with DV Widescreen. With 5x less resolution, DV isn’t going to compare to the HD that you shot so best to make them both DV.

    Thanks. So just to clarify, my workflow needs to be as follows:
    – Vegas project template = PAL DV WS
    – render out = PAL DV WS DVDA template
    – Make the DVD in DVDA = 720×576 PAL

    Hopefully the Best quality render settings in Vegas will not introduce any motion artefacts.

    I have mixed DV and HDV in the past, and I was using Sony Vegas 8 at the time, but I believe the DV camera was a locked off camera in a wide shot, hence the motion artefacts would not have been obvious.

    That’s the last time I forget to check my gear less than twice!

    That workflow is correct. You might also want to set your DVD Architect project for widescreen as well… but that only affects the menus. Your widescreen video will show correctly either way.

    I have a question related to this…

    So you always want to use the lesser of resolutions for the project, however what about the clips themselves? Maintain aspect ratio or Source?

    I ended up using the PAL DV WS project template and setting the media properties of the 1080i footage to PAL DV WS to match my DV WS footage. I then rendered out to DVDA PAL WS and then brought that into DVDA.

    I have not detected any issues of squeezing or stretching with the pixel aspect ratio, given than HDV is 1.333 and DV WS is 1.4568. This may be an issue, but I could not spot it with the naked eye. Perhaps my more learned colleagues on this forum could comment.

    Using this combination, the strobing/tearing artifacts are now gone in both the HDV and DV footage. I have some slight letter boxing top and bottom, but that is an acceptable trade-off and will be partially hidden by overscan on most TVs.

    I came across an old post in the DMN forum which suggests setting Field Order: Progressive + De-interlace Method: Blend.

    I have not tried this simple fix as I have to deliver this project within a week. I have already spent 2 nights rejigging my veg project files and re-rendering. To my naked eye, the HDV footage seems slightly more crisp and ‘pops’ a bit more which I can fake by slightly oversaturating the DV WS footage if I want to. I have not taken that option (yet).

    Given that most of the footage was taken indoors in a poorly lit church and an even more poorly lit reception, the difference is not so obvious. My next issue will be removing noise from gain as my cameras were all running in excess of 15db at the reception! But that is another battle.

    > So you always want to use the lesser of resolutions for the project

    Not necessarily. In this case the OP made a mistake by having one camera on DV while the other is on HD. In this case, we are covering up for a mistake. If you had shot a project in HD and needed to include some clips that are SD you might keep the project HD but in this case, we want to seamlessly cut between two cameras so using the lesser of the two resolutions would result in the least amount of change since you can scale the HD down and it still looks great but you can’t scale the DV up to HD and say the same.

    > however what about the clips themselves? Maintain aspect ratio or Source?

    I would never mess with the aspect ratio of the clips themselves. I would always crop to match the output aspect. Otherwise you get people being stretched and circles appearing as ovals etc.
