Render an existing project in 4K

HyperFrames keeps the composition’s layout unchanged and captures it at a higher device-pixel ratio. A 1920×1080 composition becomes a 3840×2160 file. Use the matching preset for portrait or square work:

Author a project at 4K

If the project should use a 4K canvas from the start:
Choose this when canvas or WebGL code, fixed-resolution media, or layout decisions need to know the final pixel dimensions while you author.

​
What gets sharper

For a fully sharp 4K result, use 4K source media and size canvas/WebGL buffers for the target resolution.

​
Constraints

--resolution only works when:
  • the preset has the same aspect ratio as the composition;
  • the target is an integer multiple of the authored dimensions;
  • the target is not smaller than the composition;
  • the output is MP4 rather than an alpha format;
  • HDR is not forced for the same render.
HyperFrames checks these conditions before opening the browser. Render at the composition’s native size and resize separately when a combination is unsupported.

​
Verify the file

For landscape 4K, the output should report 3840 by 2160. 4K captures four times as many pixels as 1080p, so expect more render time, memory use, and output data. Start with --quality draft for review, then render the approved version at the quality you need.
