    converting interlaced HDV to interlaced SD

    What methods are other people doing to create a nice scaled down version of 29.97i HDV video?  When you just use the clip properties to scale the image it works well but the fields end up getting blended together.  Has anybody found a way to scale down with quick results to get SD at either 29.97i or 29.97p with no field blending?

    Re: converting interlaced HDV to interlaced SD

    Check out the post on HDV Whitepaper. Suggests using the 2D CPU to scale down HDV - turn off key frames - not sure if this allows you to play with frame blending, though. I suppose you could combine this with a linear timewarp - I tried the 2D CPU last night but didn't check for field blending (tonight, maybe).

    Cheers

    Yes this would work but it kind of goes against the concept of being able to mix formats in the timeline.  To trully mix formats that also means to mix interlaced and progressive footage.  The clip properties should have a deinterlacer option to make everything native in the timeline.

     

    Right now as it is if you have 1080i HDV and want to convert to a 480i DVD you will have to spend a lot of time rendering in Liquid if it can even do it at all.

    True, but there are so many flavours of deinterlacing that having it as a drop-on effect is not an unreasonable approach (or maybe you could configure the deinterlacer to use when the deinterlace options was selected for a particular clip).
