    Hello! My problem is that there are these jagged lines in the video. They appear on certain objects (for this specific example, they are on the ceiling lights and the guys shoulders). They always end up on the shoulders.

    So I’m wondering what I’m doing wrong because there obviously has to be a button that gets rid of this. I’ve looked all over for answers but have yet to find any.

    I add it to the render que. Quality is at best. Resolution is at Full. Quicktime format with compression output H.264. I deinterlace the footage as well, which I thought would get rid of it, but the “lines” are still there.

    I don’t get it!? I’m using After Effects 6.5. Also what I do is right click the file, press interpret footage, then press main. I then click “preserve edges (best quality only)”, and that makes things a little better, but still produces some jagged lines.

    Pixel aspect ratio is D1/DV NTSC (0.9). Frame rate is 29.97. I can’t think of any other information, but if you need any let me know.

    In the example video I’m attaching to the link below, I’ve applied all the features listed above, and the video in the link is the end result.

    Does anyone have any suggestions on how to solve this problem? Thanks in advance!!

    You might try the “reduce interlace flicker” filter. It adds a very light softening that can help get rid of jaggies…

    Good luck!

    Thanks for your reply!

    I tried it, but it didn’t work. I put a link of the picture where the jagged lines are in this scene. I put it on a very low quality so the lines would stand out and have circled where the lines are.

    Also, whenever I inport footage, it appears like this. So there must be something wrong with some setting because no one else has this problem, right?

    Honestly, if you are working/editing in DV, I usually have this issue as well. It’s hard to tell since you did compress it a lot on your still photo, but it appears that’s why. Did you shoot your footage in DV?
