Mac apps for audio, video and events

Practical tools for people who record and present.

Three focused apps: two that keep multitrack audio and video recordings to a sensible size, and one that turns photos and music into a montage for the big screen. We also build custom apps when a team needs something more specific.

  • macOS 15 or later
  • Apple silicon and Intel
  • No internet connection needed
  • Your original files are never changed

The apps

Each one does a single job.

They run on your own Mac, work without an internet connection, and leave your original files exactly as they were.

Multitrack Optimise app icon

Multitrack Optimise

Smaller multitrack recordings, without losing a thing.

A digital mixer or multitrack recorder saves every channel as a WAV file of its own. An hour and a quarter of 32 channels is about 20 GB, and some of those channels usually recorded nothing at all. Multitrack Optimise listens to every track, leaves out the ones with no meaningful sound, and converts the rest to a format that takes a fraction of the space.

  • Finds the silent channels for you. Unplugged inputs, spare mics that were never used and lines that only caught hum or hiss are left out automatically — with the reason for each.
  • Exactly the same sound in about half the space. Apple Lossless and FLAC keep every sample identical. Need listening copies? AAC is about a tenth the size of WAV.
  • You make the final call. See each track’s level at a glance, hear its loudest moment with one click, and tick anything you want kept.
  • Many recordings in one go. Queue as many recordings as you like. It converts several tracks at once across your Mac’s cores, and checks there’s room before it starts.
  • Leaves your originals alone. They're never changed, moved or deleted, nothing is written over, and everything happens on your Mac.

Video Optimise app icon

Video Optimise

Video recordings a fraction of the size, and you know how big before you start.

Recorders such as a Blackmagic HyperDeck capture video at very high quality, and the files add up: two hours a week for a year is about 2 TB. Video Optimise re-encodes each recording into a much smaller copy. With its recommended archive settings that year comes to about 200 GB, and it shows you how big each copy will be before it starts.

  • Know the size before you start. Every video shows what its copy should take, with a running total, as you try settings. Nothing is converted until you click Convert.
  • The right codec for the job. HEVC for the smallest archive, H.264 to play on almost anything, or Apple ProRes for footage you’ll edit again. On Apple silicon, HEVC and H.264 run on dedicated video hardware.
  • Fewer frames, smaller pictures. Take a 50 fps recording down to 25 fps for a copy about 40% smaller, or scale it to 720p. Frames are only ever dropped, never blended or made up.
  • Every copy checked before it counts. Each finished file is reopened to confirm its picture, sound, size and length, and that it plays right to the end. A copy that fails is removed.
  • Leaves your originals alone. They're only ever read, nothing is written over, and everything happens on your Mac.

Photo Montage app icon

Photo Montage

Photos and music in. A polished montage out.

Choose your photos, put them in order and add a song or two. Photo Montage handles the timing, the transitions and the music fading out at the end. Play it full screen at a party, a memorial, a school night or a service, or export it as a movie to share.

  • Made for the projector. Plays full screen on a projector or TV while your Mac keeps the controls — pause, scrub, or loop it as a welcome slideshow while people arrive.
  • Music that lands on the last photo. Trim songs, fade them in and out, balance their volume, then Fit Photos to Music so the final photo fades as the song ends.
  • 30 transitions. From a classic cross dissolve to push, cube, page curl and ripple — one style for the whole montage, or something special for a single photo.
  • Quick touch-ups, never destructive. Brighten, warm up, crop and straighten. Portrait photos in a widescreen show can sit on a soft, blurred copy of themselves. Your originals are never changed.
  • Any screen, any shape. Widescreen up to 4K, or square and vertical for social feeds. Export H.264, HEVC or ProRes movies for TVs, YouTube or your video editor.

Custom work

We also build custom apps.

Some teams need a tool that doesn't exist off the shelf, usually one that ties their equipment, schedules and people together. We build those as native apps for Mac, iPad, iPhone and Apple TV.

The kind of work we mean:

  • Running a show's cues across audio, lighting and video from one screen
  • Getting information from planning and rostering tools to the production desk
  • Displays that show the team what's happening next

We use AI-assisted development for much of the routine coding, testing and documentation. That keeps smaller projects affordable and makes later changes and macOS updates quicker. An engineer designs, reviews and tests everything we deliver.

Most projects start with a conversation and a small prototype, so you can try the idea before committing to more.
