Apply a filter to video — MKV files, without uploading

Grade and colour a clip, starting from MKV video — here in this tab, with nothing uploaded.

How to apply a filter to video (MKV)

  1. Drop your MKV file in.
  2. Pick a look and set its strength.
  3. Save the graded clip.

Why this one stays private

Colour work means watching the footage back repeatedly. Doing that over an upload is slow; doing it here is immediate.

Questions

Does this work with MKV files?

Yes — that is what this page is set up for. MKV is the archivist's container: it holds anything, but few devices play it directly.

Which looks are included?

Black and white, warm, cool, faded and teal-and-orange, each adjustable rather than all-or-nothing.

Can I adjust brightness and contrast by hand?

Yes, alongside saturation and vibrance.
