Leumos Studio / browser grading

Color grade video online, all the way to export.

Match a shot to a reference or shape the look with the creative controls. Use Match all across the edit, review the cuts, then export finished video. Leumos keeps that color workflow together, from imported footage or a supported XML edit to a rendered result.

Free available · 1080p 8-bit export, no watermark

Scene detection and reference matching use server processing. Export uploads original footage for rendering. Read how footage is handled before you import.

The grading path

A look you can carry through the cut.

A single pleasing frame is only a start. Different cameras, exposures and scene lighting can pull adjacent shots apart. Work through the footage, check the match in motion, and decide what each shot needs before rendering the sequence.

  1. 01

    Import the footage

    Bring supported video into Studio, or import a Final Cut Pro 7 XML edit exported from Premiere or Resolve and locate its source media. Inspect the conformed sequence before grading.

  2. 02

    Set the input and find the cuts

    For supported log material, select the matching camera input transform. Use cut detection to split footage into shots, then inspect the timeline before grading.

  3. 03

    Match a selected shot

    Choose a still reference for the shot you are working on. The reference match guides its color, contrast and overall look; it is a starting decision you can inspect and change.

  4. 04

    Match and refine the sequence

    Use Match all to bring the remaining shots toward your graded shot. AI Color Correction can analyze a shot or the timeline without a reference still. Refine exposure and white balance with Balance, shape contrast with Tone, and adjust faces with Skin tone. Review the moving image with waveform and vectorscope.

  5. 05

    Export the finished video

    Review the full graded sequence across cuts and choose the rendered-video export your plan supports. Check the output on the display and delivery path that matter to your project.

What the output is

A graded video, with honest boundaries.

The deliverable is rendered video, with resolution and depth determined by your plan. It is not a promise that a reference match will be identical on every viewer, or that one pass can solve every source. Watch faces, shadows and highlight detail on the timeline; review the encoded file before handing it off.

Reference match uses a still image for one selected shot. Copy grade transfers settings; Match all uses a graded shot to match the remaining shots. Reference-match runs use the monthly allowance, including shots that Match all sends for reference matching. Copying settings and AI Color Correction themselves use no reference match. Review and refine the results across cuts.

Need a different deliverable? A specialist suite remains the right place for RAW debayering, native grade-data interchange, tracked work outside the supported Studio workflow, or specialist HDR and DCP output. Use your picture editor for broader cutting, audio and titles. You can still complete a supported color grade and export here.

Start on Free

Grade your own footage before choosing a paid plan. These are the current public Free allowances, generated from the same plan source used by the pricing page:

  • 1080p 8-bit export, no watermark
  • 10 reference matches a month
  • 10 projects
  • 1 GB cloud storage across the account

The cloud-footage allowance is shared across the account, not granted again for each project. Per-file upload limits and export choices depend on the selected plan and source.

Common questions

Before you open a project.

Can I color grade a whole video online with Leumos?

Yes. Import your footage or a supported Final Cut Pro 7 XML edit from Premiere or Resolve with its source media. Grade a shot and use Match all to match the rest of the sequence. Review and refine the shots on the timeline, then export finished graded video.

Is there a free option without a watermark?

Yes. Leumos has a Free plan with 1080p 8-bit export, no watermark, 10 reference matches a month, 10 projects, 1 GB cloud storage across the account. Cloud storage is an account pool shared across projects.

Do I need a reference image to grade footage?

No. A reference is useful when you have a look in mind for a selected shot. You can also make your own creative adjustments with the manual controls or try Smart Grade on a shot, then review the result in motion.

Can I work with log footage in the browser?

Leumos offers input transforms for supported log encodings, including Sony S-Log3, ARRI LogC3, and Panasonic V-Log. Choose the transform that matches the source before judging the grade. An input transform is not RAW decoding or HDR delivery.

Does Leumos replace my video editor?

Leumos covers the color-grading path through rendered video export. Use an editor or a specialist suite when the job calls for picture edits, audio mixing, titles, RAW debayering, native grade-data interchange, or specialist HDR and DCP delivery.

Bring the footage. Finish the look.

Start with the Free plan, establish a look on one shot, use Match all across the edit, and refine the sequence before export.
