Quality optimization

VMAF video encoding for quality-targeted compression

Use VMAF-guided sample encoding to choose a better quality target before the final video encode, without manually testing bitrate settings.

VMAF helps teams avoid guessing. Convertrilo samples the source, scores candidate encodes, and uses the selected settings for one optimized final output.

Target perceptual quality instead of picking bitrate blindly.

Use one optimized final encode after VMAF sampling.

Keep requested and effective pass behavior clear in pricing.

Apply VMAF to API, SDK, and dashboard workflows.

How it works

Encoding behavior that maps to the real worker path

These capability pages describe concrete job behavior: payload fields, worker choices, FFmpeg execution, and terminal output handling.

  1. Step 1

    Submit a job with optimize set to vmaf and an optional target score.

  2. Step 2

    The worker probes representative samples from the source.

  3. Step 3

    Candidate encodes are scored and the best matching settings are selected.

  4. Step 4

    The final output is encoded once with the chosen settings and uploaded.

Quality target control

Set a VMAF target for jobs where visual quality matters more than a fixed bitrate recipe.

Billing-safe passes

VMAF uses sampling plus one final optimized encode, so pricing exposes requested versus effective pass behavior.

Automation-ready

Use VMAF from API requests, SDK calls, folder workflows, and the Convertrilo CLI.

Feature questions

Is VMAF the same as classic two-pass encoding?

No. VMAF optimization samples and scores candidate outputs, then performs one optimized final encode. Classic two-pass is a software encoder rate-control workflow.

When should I use VMAF?

Use VMAF when you care about consistent perceived quality across varied source videos and do not want to hand-tune bitrate per file.

Does VMAF take longer?

Yes. VMAF adds analysis work before the final encode, so it is best for premium, library, course, archive, and customer-facing assets.
