Upscale video in Final Cut Pro without breaking the edit

The order that pays for itself is: cut first, pass second, conform last. Finish the edit at the project's native resolution, live with the cuts for a day, and collect only the clips that survived. Running the pass before the edit charges credits for shots you will trim, and it shows the model isolated frames rather than the sequence they will be graded and mixed inside.

There is one exception worth planning for. If the whole deliverable has to live in a larger frame — a 4K master out of a 1080p project, a vertical cut out of horizontal rushes — settle that before the edit, because frame size changes how much of each shot fits. Run one representative shot through the pass, judge it at full size on the display you grade on, and only then build the sequence around the answer.

Keep the pass outside the creative loop. Do not spend credits rescuing a clip you have not decided to keep, and do not run the same clip twice hoping the second attempt improves on the first: the second pass reads the first pass's output and mostly amplifies whatever that output already got wrong.

Spatial Conform is the setting most people meet first, and it is easy to mistake for an upscale. It decides how a clip whose frame size differs from the project is fitted into the project frame: fit keeps the whole image and leaves bars, fill covers the frame and crops the overflow, and none lets the clip sit at its own size inside the larger frame. All three are placements of pixels you already have.

That is a resampling decision, not a restoration one. It decides what happens to the edges and how much of the frame survives the trip; it says nothing about how much real detail exists. A smaller clip conformed into a 1080p project carries exactly the information it carried before the conform — the same texture, redistributed across more pixels, with any compression blocks magnified along with the picture.

The distinction changes what you export. If conform is cropping a shot to make it fit, the pass should receive the full frame rather than the cropped version, and the crop should be reproduced deliberately on the result. If the fit is leaving bars, strip them or accept them knowingly instead of letting a model guess what belongs in the letterbox. And if conform is doing nothing because the clip already matches the project, leave it alone: there is no rescale to undo.

Export one master at the clip's native size, not at the size you are aiming for. Exporting a 1080p clip at 4K hands the model pixels Final Cut generated by upscaling, and the model has no way to tell those apart from captured detail — it will treat interpolation as evidence. Native in, native out is the rule for the source.

Final Cut makes this unusually painless, because the ProRes pipeline is native to it and Apple Silicon plays those files back without complaint. Export the slice as ProRes 422 or ProRes 422 HQ: the codec exists to survive another processing step, so what you hand over stays close to what the timeline actually holds. A high-bitrate H.264 export is acceptable for a delivery-bound clip, but it is a weaker source, because H.264 already discarded detail before the pass began.

Export once, from the original media, and export only the range the edit uses. Re-exporting a file that was already exported adds a whole generation of compression before anything runs, and the model will faithfully enlarge those artefacts along with the picture. Trimming the export to the shot is not just tidy — you are billed for the seconds you submit, and the rest of the timeline does not need the pass.

A Final Cut library is managed by default: importing brings media into the library unless you deliberately reference it in place. That decides where the enhanced file ends up, because a download is only a file on disk until something brings it into the library that owns the project. Knowing which mode your library uses is the difference between a clean swap and a clip that goes offline a week later.

Two habits keep it clean. First, import the enhanced clip into the same event, or a paired event, with a suffix that marks the pass rather than a rename — that way you can still sort by the original clip name and see at a glance which version is which. Second, know whether the library copies media in or references it: if it copies, the download is disposable once the import finishes; if it references, move the file somewhere stable before it is cleaned up, or the clip returns offline.

None of this is visible to the hosted service. It never reads the library, the event, the project file or the effects stack. It receives a video file — uploaded, or fetched from a public HTTPS URL — processes it and returns a file. Everything about where that file lives afterwards is Final Cut's business, which is also why the pass cannot disturb anything you have already cut.

Download the result, import it, then replace rather than re-cut. The replacement workflow is the reason this round trip feels natural in Final Cut: point the sequence clip at the enhanced media and the trims, the effects stack, the keyframes and the connected audio references follow the clip onto the new file. Cutting the shot in again by hand throws all of that away and invites a sync error you will chase for an hour.

Watch the geometry. Replacement is faithful only when the new file has the same duration and cadence; if the pass changed frame rate or length, expect to re-time and to re-check anything that depends on timing. If the enhanced file carries a different frame size, decide explicitly whether the clip should be conformed, scaled in the inspector, or left at its native size inside the project frame — do not let a default decide for you.

Grade after the round trip. Anything baked into the export becomes part of the source the model reads, and a heavy look can push a model that is trying to estimate texture. Keep the original clip disabled on a track above the replaced one until the sequence is signed off, so a comparison is one toggle away rather than an afternoon of re-exporting.

Connected audio is the quiet advantage of working this way. Audio that is connected to a video clip in Final Cut moves with it, and a media replacement preserves the connection — which means the pass never has to touch sound, and a mix you have already balanced stays exactly as you balanced it.

The hosted pass has no audio handling at all. The request carries the video, the model, the resolution tier and the billed duration; there is no audio track in it and none comes back. That is less a limitation than a division of labour: the picture goes out and returns, the sound never leaves the edit.

Check one thing before replacing. If the clip carries a retime, a speed change or any duration-altering effect, confirm the enhanced file covers the range the cut actually uses. A trimmed clip may show only a fraction of the source, and there is no reason to pay for seconds the sequence never displays.

At the Standard model, 1080p bills 540 credits per minute of submitted source footage, which is 32,400 credits an hour. That is the figure to budget with, because it is the tier most edit work actually needs: a 1080p project that has to come back as a clean 1080p master, or a 1080p clip that has to survive a 4K delivery.

4K on the same model bills more per second than 1080p, and the difference buys compatibility with a delivery spec rather than recovered detail. Convert to money at the Creator yearly rate of $0.0093 per credit: a minute of 1080p Standard work is about $5.01, an hour about $300. Creator's 106,800 credits cover roughly 197 minutes at Standard 1080p, or about 53 minutes at Standard 4K.

Read those numbers against your own cut, not the project length. A twenty-minute documentary with ninety seconds of genuinely poor archive footage is a ninety-second job; the credits follow the seconds you submit, not the runtime of the sequence. One source can run up to 10 minutes, but a long project is normally handled clip by clip — which is also the only way to judge one result before committing the rest.
