Every clip.
One file.
Zero catch.
ActionCam Concatenator joins your dashcam, GoPro, drone, and phone footage into a single 4K video — trimmed, reordered, and rendered with FFmpeg, entirely on your own machine.
Trim the boring parts.
Keep the good ones.
Frame-accurate start and end points, plus mid-clip cuts for the sections you never wanted to keep — done per clip, before anything gets compiled.
Set start/end, mark cuts, and watch the timeline turn red where footage gets removed — the queue on the left keeps every clip's thumbnail and resolution in view while you work.
What it actually does
Every feature below ships in the app today — nothing here is a "coming soon."
Batch by the folder
Add files one at a time or a whole folder at once. Drag rows to reorder, or right-click to manage the list.
Cut mid-clip
Set exact start/end points per clip, then mark and remove any number of sections from the middle before it's compiled.
HDR & VFR aware
Mixed resolutions, variable frame rates, and HDR footage from different cameras go in without breaking the export.
Tunable output
Start from a recommended, balanced preset, or dial it in yourself — and strip the audio track entirely if you don't need it.
Cross-fades & music
Add a transition between clips with your own duration, or lay a music track under the whole compilation.
Scrub before you render
Play any clip and watch the exact in/out points on the timeline — kept sections in blue, removed sections in red.
Queue multiple outputs
Line up several compilations at once. Output file, clip list, status, and progress are all tracked in one queue.
Drag, drop, done
Drop files straight onto the window. Thumbnails and resolution show up immediately, so mismatched cameras are obvious.
Actually free.
There's no metered tier hiding behind this one. Every clip you own, every compilation you run, for as long as you want to run them — because the app renders on your own machine with FFmpeg, there's no server-side cost to ration in the first place.
Built for footage that doesn't behave.
Dashcams, GoPros, drones, and phones rarely agree on codec, frame rate, or resolution. ActionCam Concatenator was built specifically to take that mess in and hand back one clean, correctly ordered 4K file — with the boring parts already cut out.
