Upload a multi-gigabyte master without babysitting it

Drop a multi-gigabyte master on the project and go do something else. A network blip costs you a piece, never the whole upload.

A finished master is not a small file, and on a lot of platforms the moment you drag one in is the moment you have to sit and watch a bar. The deal here is different: drop the file on the project, go make coffee, come back to a video that already plays.

Drag it in and walk away

Open the project, drag the file onto it. That is the whole instruction. There is no separate flow for big files, no setting to hunt for, no helper app to install. The upload panel in the corner keeps count while you carry on working elsewhere in HoldFast: open another project, answer a comment, start a second upload. The panel follows you.

A blip does not cost you the file

Large uploads travel in pieces, several at a time. If the connection drops for a moment, the affected piece waits and tries again, pausing a little longer on each attempt so it is not firing straight back into an outage that has not cleared. The pieces that already landed stay landed.

That is the part worth internalizing: a hiccup half an hour into a huge master costs you the piece that was in flight, not the half hour. And if a file does fail outright, it waits in the panel with a Retry button beside it (Retry All covers a batch), so you pick up where you were instead of starting the evening again.

Playable in seconds, sharpening behind you

You do not wait for the whole file to be ready before the video is useful. Moments after the bytes land, the asset has a thumbnail and plays. A pulsing amber Optimizing badge means the sharpest quality is still arriving in the background, and you can watch, comment, build a review link, and send that link while it is still showing. See What "Optimizing" means.

A new cut rides the same road

Replacing a cut is not a different mechanism with different rules. Upload the revision as a new version of the same asset and it travels the identical path, with the same piece-by-piece resilience on a big file, and the link your client already holds plays the new cut once it goes live. See Send a new cut without breaking the link.

The honest part

A slow connection is still a slow connection. Nothing here makes your outbound line faster, and a multi-gigabyte master on a modest connection takes the time it takes. The promise is narrower than speed, and more useful: a blip in the middle does not cost you the upload.

Two things to keep in mind. Closing the browser tab still stops a transfer in flight, so leave it open until the bar completes. And every plan carries a per-file ceiling, listed with the rest of the numbers in Upload large files. If whole shoot folders land on your drive regularly, a watch folder uploads them for you as they arrive.
