Send, play and review camera files.

Drop a camera card, a folder or a single file — 5 GB on the free profile, 500 GB on Solo, 1 TB on Studio and above, up to 500 files in one transfer. Pick who gets it from your crew and client books, or type an address, and the email goes out under your company with your name and number on it. Or take one link and share it anywhere. The link exists the moment the upload starts: paste it while the files are still on their way, and their page shows what has arrived and fills in the rest as it comes. The email goes out when the last file is up.

A browser can’t play MXF, so KitSlate makes a preview from the camera file and the page plays that. When the camera recorded a proxy beside the clip, the proxy plays at once; when it didn’t, the preview is ready a few minutes after upload, and the page shows how far it has got — copying, encoding, ready. Whatever plays, the download is always the untouched master. Under the picture, the spec sheet reads the file itself — the MXF header, the camera’s XML, a WAV’s bext and iXML — and lays it out in three groups: Picture, Sound and Source.

Camera files often carry four or eight separate tracks: the boom on one, a lav on another, the camera mic on a third. Each gets its own lane with a switch, a solo button and a slim meter with peak hold, dBFS and loudness. One Audio menu, laid out like VLC’s, picks the tracks and how they reach your ears — Stereo, Mono, Left, Right or Reverse.

Footage shot in a log curve looks flat and grey on a normal screen. The player shows it as Rec.709, worked out from the camera’s own metadata, and labels where the look came from. A LUT the clip carries, or one included with the card, is used first; a show LUT you attach to the transfer comes before both, so everyone sees your look.

Pause anywhere and write. The note carries the clip’s own source timecode, drop-frame read as drop-frame, and reaches you as a chip that opens the clip at that frame. You answer on the same thread, and they see your reply on their page and in their email.

Drag the yellow handles on the filmstrip to set an in and an out, linked to the A-B loop, and download that part. What comes out depends on the file, and the menu says which before anything is made.

With the Pro review tools — every paid plan, and either side paying unlocks them — every audio and video file can have a transcript: what was said, one line at a time, each line with the clip’s own timecode. The words light up as it plays, a press on a line goes there, and a search narrows the lines to a word. It is made automatically on KitSlate’s side by Workers AI (whisper-large-v3-turbo), from the track with speech, and it is off until you switch it on.

Three layouts, and every tool works in each. The page keeps the files, the player and the conversation side by side. Expanded fills the window: the picture takes the space, with the audio rail, the clips and the file’s info beside it, each one switchable — hide both for a cinema layout. Full screen is the picture alone, the controls tucked away until you move.

Open a transfer you sent and you get the page your client gets — the same player, the same tracks, the same spec sheet — with an Activity panel only you see: every open, play and download, with the time. The Sent tab reads in sentences: Downloaded everything · today 2:20 pm, Watched a preview · hasn’t downloaded yet. Their messages and yours read as one conversation, under the transfer, in Activity and in your inbox.

Everyone you send to can play and review, comments at a timecode, the spec sheet, listen as stereo or mono and download the whole file, on any plan. Every paid KitSlate plan includes them — for you, and for the people you send to. When you send from the free plan, a client with a paid KitSlate plan of their own signs in on the page and gets them there.

Your browser uploads straight into our storage, with nothing in between to slow it down. The file goes up in parts over as many as 32 parallel connections, so one slow stream never sets the pace. Before you start, the speed test on the Send page measures your line and the route to storage, and sets the part size and the connection count from what it finds. Measured from our office in Manhattan on a 2 Gbps fiber connection: 1.82 Gbps up to storage over 12 connections and 2.04 Gbps back down — 100 GB in about 8 min, 1 TB in about 1 h 21 min. Your times are your line’s; the test tells you before you start.

Every feature reads what the others already know. These are the ones this page's work flows into and out of.
