  Background banding when compressed in AE?

  Posted by Daniel De silva on February 10, 2015 at 9:46 am

  Hi Guys!

  I have a small issue, I added a background layer (72 dpi – JPEG) into my AE file, (both 1920-1080 res). When I go to render it at H.264 I receive banding on my background? Although when I export it from .ps there is already a slight bit of banding in the first place which I don’t want, but obviously not as much.

  What’s the easiest way to smooth it out?

  The video is for web.

  Thanks!

  Dan.

  Add a bit of noise.

  I’ve tried adding noise but it only reduces it slightly, (.8 noise amount). I don’t want to crank it up to far incase it begins to ruin the image.

  Hi Dave,

  I’m rendering out to H.264 through AE. I’ve managed to fix the banding problem! Most of it was due to the initial image.

  I have another question and since you seem to know what you’re talkingabout thought i’d post it to you!

  How do I transcode a 1080p video to a 720p video?

  Thanks,

  Dan.

  ah ok great thanks. I tried re-sizing the comp to 720p which worked fine, but when i want to export it as a mp4 (presuming h.264 is best for web) it appears washed out :/ any advice?

  Which codec would be best for loseless quality? thanks! yeah i figured the nesting and resizing down to 720p, but when i render it to h.264 the colour quality is very washed out, when i render it in quicktime with a h.264 codec the colour image is good? Is what you described above the best way around this?
