Dealing with a Stripey Tie
I’ve received some interview footage of a guy wearing a stripey tie – I’m sure many of you are familiar with the way it makes the video shimmer.
Does anyone have any techniques for improving these artifacts?
Or is it something I’ll just have to live with?Many thanks!

Try deinterlacing the video.

Mr. Schmee,
What you’re observing is something called a “moire” pattern. Essentially, the pattern on the tie is “testing” the resolution of the video by presenting a level of detail that cannot be resolved by the camera.
The best solution for this problem is to add a slight gaussian blur to the offending area. This effectively reduces the resolution of the image to the point where it ceases to create the offending pattern.
Good luck.

If it bothers you tremendously on the computer display, be sure to test the output on a video monitor before committing to a process.
You have some choices, as others have pointed out. Another might be to resize the clip slightly to change the frequencies of the stripes interfering with scan lines; 2 to 5 percetn may be all you need.
Anything drastic will cause a bit of a change to the appearance of this particular set of clips and your client may not want that. We’ve had to sell a slight stylistic change to help hide artifacts like these. “Hey, let’s put this interview in a nice box and kinda tilt it so it picks up a glint.” Resizing the clip, adding a pixel of blur and putting a glint effect over the video hides lots of bad video.bogiesan
