Triage: Which Bad Clips Are Worth a Pass
Spend the diagnosis before the credits. Half of what arrives labelled low quality was never going to come back.
Low quality describes a result, not a cause, and the cause decides whether anything can be done. A clip can be poor because it was encoded at a bitrate far below what the content needed, because a small frame was stretched to fill a large one, because the subject moved during the exposure, because the sensor was working in light it could not handle, or because the file has been uploaded and downloaded several times and each round trip wrote another layer of artefacts into it. Those have very different prospects, and the first three minutes with the file are worth more than anything spent on it afterwards.
What is on offer works within the frame you have. Video HD in the OpenFilmo workspace is described in its panel as boosting clarity and fps, takes MP4 and costs 32 credits with an estimated 1 to 4 minute wait. It publishes no output size and no magnification factor, so this is not a route to more pixels: footage that needs a larger frame belongs on the AI video upscaler page. This page is about whether the clip you already have, at the size it already is, is worth spending a run on.
What it does
Built for this specific job, not a generic editor.
Detail that survived the damage
Where the source still carries structure — visible edges, recognisable texture, some variation inside flat areas — there is something for a clarity pass to strengthen. Where an area has been averaged flat, there is not.
Light compression damage rather than heavy
Mild blocking and soft edges from a single low-bitrate pass respond better than the rough, patchy damage of a file that has been re-encoded repeatedly. Counting the generations is most of the diagnosis.
A cheap, honest go/no-go test
One run on the worst clip in the set costs 32 credits and an estimated 1 to 4 minutes. That is a reasonable price for an answer that decides whether the other forty files are worth anything at all.
MP4 in, browser out
MP4 is the accepted input and the work happens at app.openfilmo.com, so a laptop with no editing software installed can still do the triage on site.

How it works
Four steps, no timeline to learn.
Pause on a frame and look at full size
Check one edge and one textured area. Residual contrast in the edge means something survived; a flat, waxy patch means it did not, and no pass will reconstruct it.
Count the generations
Work out how many times the file has been saved, clipped, shared or re-uploaded. Every one of those is a compression pass, and artefacts from them sit exactly where real detail would be.
Test the worst clip first
Run the file you are most pessimistic about. If that one improves, the rest of the set probably will; if it does not, you have spent 32 credits instead of several hundred finding out.
Write off what fails and move on
Deciding not to enhance is a real outcome and often the correct one. Footage that cannot be recovered is better replaced, recaptured or cut around than run through a tool a second time.
What people use it for
The jobs this actually gets used for.
Family and archive transfers
Tape and early digital material digitised once at a modest bitrate, where the capture resolved the detail and the transfer is what degraded it.
Contributor and audience footage
Clips sent by other people, usually compressed by whatever messaging tool delivered them. Triage each one rather than treating the batch as uniform.
Platform downloads of your own uploads
Material pulled back down after a platform re-encoded it. Where an original still exists, enhance that instead; where it does not, this is the salvage route.
Old webinars and course captures
Recordings where the content is a person and a screen, and the complaint is legibility. Slides and captions improve where the letterforms survived, and do not where they did not.

Why some footage cannot be recovered at any price
The ceiling is set by what was recorded, not by what is spent later.
The useful mental model is that detail is either in the file or it is not. Compression discards it to save bytes, an undersized frame never held it, and motion during the exposure blended it away. In each case the information is gone rather than hidden, and a clarity pass has nothing to strengthen — it can only raise contrast on what remains, which on badly damaged footage tends to make the damage more visible rather than less.
That is why triage matters more than settings. The same tool produces a usable result on one file and nothing on another that looks equally poor in a preview, and the difference was settled long before either file reached the workspace. Learning to see that difference in a paused frame is the skill that actually saves money.
There is also a legitimate alternative that has nothing to do with tools: recapture, replace or cut around. A clip that cannot be recovered can often be shortened, reframed or swapped for a still, and those decisions cost nothing. Being willing to write material off is part of working quickly, not a failure of the tool.
Credits and plans
Every tool draws on one shared credit balance.
Each run costs 32 credits with an estimated 1 to 4 minute wait. The Free plan gives 30 credits a month, so it does not cover one — worth knowing before you plan a triage pass around free credits. Starter is $9 a month for 400 credits and two parallel tasks, which is twelve runs; Pro is $19 for 1,000 credits, three tasks and a priority queue; Studio is $59 for 4,000 credits, six tasks and API access.

Frequently asked questions
When should I not bother?
When a paused frame shows flat, waxy areas with no residual edge, when the file has been re-encoded several times, or when the damage is motion blur. In those cases there is little left to strengthen, and the run will mostly raise contrast on artefacts.
How much does a run cost?
32 credits per MP4, with an estimated 1 to 4 minute wait. Free gives 30 credits a month, which is not enough for one; Starter at $9 gives 400 credits, or twelve runs.
What formats are accepted, and can you fix blocking?
MP4 is the accepted input. Mild blocking from one low-bitrate pass can read better afterwards; heavy blocking where detail was discarded cannot, because the information is gone rather than hidden.
Is this a way to get a bigger video?
No. Nothing here publishes an output size or a magnification factor — the panel names clarity and fps. Footage that needs a larger frame belongs on the AI video upscaler page.
Can I use the output commercially?
Yes. Commercial use is included on Free and on paid plans and exports carry no watermark. You still need the rights to the footage you upload.
