    Hey all,

    I have the infuriating experience that After Effects adds black lines AFTER I render. See the attached screenshots.

    The composition itself is superclean, as you can see from the pre-render screenshot.

    The moment I send it to Media Encoder, and render with a H264 medium bitrate, it shows up with these lines.

    Please help.

    I’d love to keep my aspect ratio. 424 x 888 but willing to change for the greater good.

    Many thanks,

    is the frame size in ME exactly the same size as in AE? could be the issue

    Probably the composition’s dimensions are not a mulitple of 8, which they need to be for H264 encoding, or Media encoder is doing something else with regards to the cropping/fill settings.

    I could be wrong about the 8×8, could be 4×4, but it definitely doesn’t allow for odd numbers

    Have you tried an export via the Render Queue instead of Media Encoder? It would be interesting to see if a lossless export (or an image sequence) displayed the same lines.
