Compressor 5.3 — macOS

You just exported a Final Cut Pro project and need it in a different format for a client. Compressor is the tool that handles that conversion, and getting started is simpler than it looks.

First steps with Compressor

1. Add a source. Drag a video file into the Compressor window, or choose File > Add Source.
2. Pick a preset. The settings sidebar on the left shows Apple device, HDR, HEVC, and MXF options. For a quick test, choose an Apple Device preset like HEVC 1080p.
3. Apply the preset. Drag the preset onto your source in the batch area, or select it and click Apply.
4. You can also add a post-encode action, such as copying the file to a folder or running a script.
5. Start the batch. Click the Start Batch button and watch the progress. Compressor uses hardware encoders on Apple silicon for fast H.264 and HEVC output.

That's the whole workflow. Once you're comfortable, explore the immersive metadata viewer and 360° video options. Compressor works with Final Cut Pro and Motion, so your export settings carry over cleanly.

A full workflow: preparing a multicamera project for broadcast delivery

Let's walk through a real job from start to finish. You've finished a multicamera edit in Final Cut Pro — interviews, b-roll, a couple of 360° clips — and the broadcaster wants an MXF file with specific audio routing. Here's how Compressor handles it.

1. Send from Final Cut Pro. Inside Final Cut, choose File > Send to Compressor. The project appears in the Compressor batch area as a single source, keeping all your timeline settings intact.
2. Set the video format. In the settings sidebar, open the MXF group. Pick the preset that matches your target spec — for most broadcast work, that's OP1a with AVC-Intra or XDCAM. Drag it onto the source.
3. Adjust the audio. With the source selected, open the inspector. The audio tab shows the project's original channel layout. For a 5.1 AAC output, you can route the tracks here. If the broadcaster needs a stereo mixdown alongside the surround track, add a second audio output using the custom settings in the inspector.
4. Handle the 360° clips. If your timeline contains 360° video, Compressor preserves the spherical metadata automatically. Check the immersive metadata viewer before encoding to confirm the projection is correct. This is new in version 5.3 and saves a lot of guesswork.
5. Set a post-encode action. In the Actions section, choose Copy to Folder. Point it at a network share or a local directory. You can also add a second action to run a script — for example, renaming the file according to your client's naming convention.
6. Distribute the encoding. If you have other Macs on the same network, turn on distributed encoding in Compressor's preferences. The app splits the job across available machines, which cuts total time for a long multicam project.
7. Start the batch. Click Start Batch. Compressor shows a progress bar for each source. Once it finishes, the file lands in your output folder and the post-encode actions run automatically.

How Compressor fits with other apps and macOS features

Compressor is part of Apple's pro video ecosystem, but it also works well with standard macOS tools. Here are a few ways it connects.

• Final Cut Pro and Motion. Export settings from Final Cut carry over when you send a project to Compressor. Motion projects that use the same rendering engine transcode without re-rendering the motion graphics layer.
• Automator and Shortcuts. You can wrap a Compressor batch inside an Automator workflow or a Shortcut. For example, drop a file into a folder action that opens Compressor, applies a preset, and moves the output to a shared drive.
• Mail. The post-encode email action sends a notification when the batch finishes. Useful for long overnight encodes — you get a message when it's done.
• Finder tags and smart folders. Set a post-encode action to add a Finder tag to the output file. A smart folder can then collect all tagged broadcast files in one place.
• Hardware encoding. Compressor uses the media engine on Apple silicon and the Quick Sync hardware on Intel Macs. The app decides which encoder to use based on the preset, so you don't have to configure anything.

Client sends a two-camera interview, needs H.264 and HEVC

It's Tuesday morning. A client sends a 45-minute interview recorded on two cameras. They want an H.264 master for review and an HEVC version for their web platform. Here's how the session goes.

I open Compressor and drag both camera files into the batch area. They're separate clips — no timeline yet. I set the first clip to the Apple Devices 1080p H.264 preset and the second to HEVC 1080p. The inspector shows the audio as stereo AAC on both, which is fine for review copies.

For the post-encode action, I choose Copy to Folder and point it at a "Client Review" folder on the desktop. I also add an email action to send a note to the producer when the batch finishes.

I click Start Batch and let it run. The progress panel shows each source independently. On a multicore Mac, both encodes happen in parallel. When they finish, I get an email and the files are already in the review folder. Total hands-on time: about three minutes.

Later that week, the client approves and needs a broadcast version. I send the same clips from Final Cut Pro to Compressor, apply the MXF OP1a preset, set the audio to two-channel PCM, and run the batch. The immersive metadata viewer lets me check the stereoscopic settings before encoding — useful because one of the clips was shot in anaglyph format.

Fix the tripping points that stall a Compressor job

Even with a straightforward app, a few things trip people up. Here are the ones I see most often, and what usually fixes them.

Source doesn't show in the batch area

Compressor accepts common video formats, but not everything. If a file doesn't appear, check that it's a supported container — .mov, .mp4, .mxf, and .mts are safe. Also confirm the file isn't corrupted by opening it in QuickTime Player first.

Preset won't drag onto the source

This usually means the preset doesn't match the source's characteristics. For example, a 360° preset won't apply to standard footage. Look for a preset in the same category as your source type. The settings sidebar groups presets by format, which helps narrow it down.

Audio routing is wrong in the output

Compressor's inspector has an audio tab that lets you remap channels. If the output has silence on some tracks or the wrong mix, open the inspector before encoding and check the channel assignments. For 5.1 AAC output, make sure the source actually has six channels — stereo files won't expand into surround.

Distributed encoding doesn't find other Macs

Distributed encoding relies on Bonjour, so all Macs need to be on the same local network and have Compressor installed. Open Compressor's preferences, go to the Distributed Encoding pane, and make sure the service is enabled. Firewall settings can block discovery — check that Compressor is allowed in System Settings > Network > Firewall.

Post-encode action doesn't run

Actions are attached to individual sources, not the batch as a whole. After the batch finishes, check that you applied the action to each source. If a file copy action fails, the destination folder might not exist or might be read-only.

HEVC output looks blocky

HEVC data rate limits on Apple silicon can produce lower-quality output if the bitrate is too low. In the inspector, look for the data rate limit setting and raise it. The new HEVC data rate limit support in version 5.3 gives you more control on Apple silicon Macs.
