How to Remove Interlace Lines from 1080i video footage - Deinterlacing 1080i


Although many tech advancements we've had over the past few years, interlaced (It is the "i" in 1080i) video seems to have stuck around It's in your cable, your televisions, and your camcorders. Sometimes for better playback and easier editing, you may need to remove the interlace lines from your 1080i video footage. Now in this article, we give you an instruction how to deinterlace 1080i video easily.

Q1: I am experiencing horrible scan lines(interlacing) with my video filmed in AVCHD 1080 60i. Any ideas? How can I remove the interlace lines from my footage.

Q2: How do I remove these? Shot 1080 24p on the HVX-200. Converted to quicktime files through P2 Log. Imported quicktime files into FCP 1080 60i DVC-PROHD timeline (couldn't find 1080 progressive option). The footage has interlace lines all over it. What needs to be done? A de-interlacer? A different timeline/sequence preset?

Essentially, when you're dealing with interlaced video you're really only seeing half the resolution because the image is split into two fields that alternate very quickly. With 1080i video, you only get half of 1,080 lines of resolution (meaning 540) in each frame. In many cases this isn't a big deal, but it starts to show up in interlaced artifacts during high amounts of motion in any given frame.

Basically, objects in fast motion will look like they're smearing cross the screen instead of looking natural. There are also numerous issues that can arise when displaying interlaced footage on progressive displays like HDTVs, for example. While 1080p is definitely your best bet in terms of highest resolution, don't think that 1080i is just as ideal because the number's the same. So, deinterlacing your 1080i video files is necessary. Below is how.
