After Effects changes Comp Size when renders

[The Real5CAA]

Hello,

When I render my composition on 1080 x 1080 (1 : 1 ratio). My Composition stays on 1080 x 1080, but it changesn when I use HandBrake to change the format it converts it to a different comp size. The Converted comp size is not changeable. How do i fix this issue?

You should be using the Adobe Media Encoder to render your h.264 MP4 files. It does a lot better job and you have more control. If your original file is rendered to any standard size and frame rate and Handbrake cannot handle it, then it is a Handbrake problem.

You should also not be messing with the rendering settings until you have a very good understanding of video standards and compression. The presets were created by folks that know what they are doing and most of the time, enthusiasts that fiddle with the knobs just foul things up and don't end up with as good a product as they would have using the presets.
