deinterlace video
Hello,
since 7 years I’m doing video editing using Vegas Video, shooting my video with cellphones, a miniDV canon camcorder and a memory card Samsung mp4 (h264) camcorder.Everytime i have to render it same question, same amount of time (hours and days) looking around forums and no solution to my problem: how do i deinterlace my video (in a reasonable way?).
My problem is that the rendered video when seen on the computer has the typical interlace horizontal line (when panning or zooming) and (much more annoying) when doing slowing down the video.
I did try with preferences of the rendering, almost every possibility.My desire is to trow away the half frame, dont care about the vertical resolution loss. I cant believe it’s so difficult, but i never succeed in doing this. Anyone can help?
I just upgraded my software and now I’m using vegas pro 9 64 bit on windows 7 now.
thank you everyone.

Of your three sources I’m guessing that the cellphone and mp4 camcorder are progressive and only the miniDV is interlaced. In this case, you might want to render the miniDV to a progressive format before editing and use that to edit with. Then keep your project progressive so that everything will be progressive all the way through your workflow. This should stop any interlace issues you might be having.

You’re absolutely right about the miniDV, but also the mp4 from camcorder comes out interlaced…
So your suggestion would be to open with vegas the original file, render it all in a progressive (says.. avi DV progressive, force resample, deinterlace method interpolate ?) and then use the output to do my footage right?
I will do more try….
still looking for a way to throw away the “second half” frame of the interpolation 🙂
if anyone want to have a look at an extract of the final render (not so bad, but it’s really annoying me this interlace effect…. like horizontal blur…) there is the link (divx, 20 seconds) https://www.megaupload.com/?d=5LA76AA2

All you need to do is set your deinterlace method in the project properties to interpolate and Vegas will throw half of the fields away for you.
Since two of your three sources are interlaced, why not set your project up for the interlaced video and then just render to progressive on final render. Vegas will deinterlace for you if the media properties are set properly (i.e., the interlaced media is correctly flagged as interlaced in the media properties)
You can also use Mike Cash’s Smart Deintelace filter if you don’t want to render first. There should be no need for all of this if you set up your project and meida correctly and render as progressive.

Thank you for the kindness! I will try these things as soon as I have some time. I never checked the flag in the media proprieties… Maybe I was missing that part and Vegas treated those media as progressive, resulting in bad final render for the clip that were slowed down! Hope is just that, I ‘ll check and post results!
Bye! Carlo

You were right, the reason why I get so crap result was the flag in the media propieties set to progressive. I Didn’t know the existence of the flag, I thought was intrinsic in the format specs the information about the interlace method… Now it’s much better, happy to know was so easy, sad I didn’t realize that before! I still hate the guy who had this great idea, ‘ let’s interlace’……..
Thank you for guiding me, and good luck on your stuff!
