    De interlacing without plugins?

    Lets say I wanted to remove the lower field from all the video in my timeline without using any plug ins. How would I do this?

    Re: De interlacing without plugins?

    I'm not in front of the box at the moment, but there is a way that one can deinterlace material once it's in the timeline by adding a Timewarp to a clip (keeping the speed at 100%) and choosing "Both Fields" as the "type" of timewarp, then choosing an Interlaced source and a Progressive output.  There's also an "Adaptive Deinterlace Source" option available at this point, I believe.  That's going to give you your best looking deinterlacing w/in AVID, I think.  

    Theres also the option of just choosing "Duplicate Field" as the type of warp processing, but then you're only getting 1/2 the information.

    Man this stuff is so confusing to me. All the time warp types of speed changes seem to be geared towards interlaced sources. I assume that when you use progressive sources (which I'm sure is 90% of broadcast material these days), the speed change types behave differently? Are the avid engineers aware of these types of changes in our industry or do we need to let them know that interlaced sources are a dying breed?

     

    Any way, back on topic: I like the sound of the 'Adaptive Deinterlace Source' you speak of. Is this a filter and where would I find it? I find the word 'duplicate field' very confusing especially when my objective is to remove the field. Duplicating a field just sounds like a bad idea for anything....and when you say it loses half the information...doesn't that apply to any sort of de-interlacing? 

    Are there easier ways to do this with plugins?

    Yes, setting interlaced versus progressive in the motion fx editor DOES matter as to how the footage is treated. Not sure what you want Avid to change. There are I and P projects. And the Motion Effects editor allows you to handle both.

    If you choose Blended Interpolated or FluidMotion, both original fields will be blended or morphed into a single progressive frame. 'Duplicated' will discard each second field.

    I've used SpeedRamp in the past for adaptive deinterlacing, but that was before Avid's current Motion Effects Editor came into being.

    There is also the workflow of keeping everything in your timeline interlaced but making QuickTimes out of the software deinterlaces.  (May have nothing to do with this thread, but wanted to list in - just in case.)

    Export/Options/QuickTime Movie/Custom (not same as source) - then click Format Options and then Size.  This gives you the option to "Deinterlace Source Video".  It does nothing to the media or the stuff in the Avid software, but gives you a nice progressive QuickTime.  (Takes a loooooooong time.  But worth it.)

    I have 7 Avids. All of them run on systems approved by Avid. Yeah... that's a lie ;) [view my complete system specs]
