A 4 GB export, and proof they watched it.

The export finishes at 4 GB. Email is out. The client isn't going to install anything, and you aren't going to explain how a shared drive works to a producer who is on set.

So it goes to WeTransfer, and you find out three days later that the free tier will not tell you whether anyone opened it.

Send it once, know it arrived

Campsend takes up to 20 files in one delivery, 2 GB on the free plan, 15 GB on Pro, 50 GB on Studio, 75 GB on Studio Pro and 100 GB on Team, and emails the recipient a link. The link works for 30 days and then stops on its own.

Your Sent page shows when the delivery was first opened and when a file was first downloaded. So when the note on the call is "we haven't had a chance to look yet", you already know whether that's true.

Notes come back on the same page

Turn on replies and the client can upload straight onto the delivery page. A marked-up PDF, a voice memo, a replacement asset. It lands on the delivery in your Sent page rather than in a thread you have to search.

When the cut changes

Replace the file and the link they already have starts serving the new version. You don't send a second link, and they don't accidentally review v3 after you shipped v4.

Where it doesn't fit

One delivery holds 15 GB on Pro, 50 GB on Studio, 75 GB on Studio Pro and 100 GB on Team. That covers a cut, a graded export, and a feature-length ProRes master at 1080p. A 4K master of the same feature runs past even Team, and it should keep going wherever it goes today.

There's no review timeline, no frame-accurate comments and no player. Frame.io does that and does it well. Campsend takes over once the edit is approved.

If Dropbox is what you send from today, here is the same comparison at length.
