30 actions, with no time limit

The trial is tied to your PC and verified online. An internet connection and the trial service are required to start new work. Reinstalling does not restart the trial.

  • A recording session counts once, when you save its first mark. Additional marks in that session are included.
  • A clipping run counts once per recording. A reel and separate clips created together count as one run. Each recording in a batch counts separately.
  • A project assembly, including combining existing reels, counts once.

Failed or cancelled work releases its reserved action when the service reconnects. An interrupted run can count if completion cannot be confirmed.

After all 30 actions, existing recordings and outputs remain yours. You can still view them, edit saved marks, and use Clean. Accounts are free. Paid trials and upgrades are currently unavailable.

Before your first recording

  1. Install OBS Studio with WebSocket support and enable its WebSocket server.
  2. In Flowmaster Settings, choose your recordings folder and enter the OBS connection details.
  3. Use MP4 recordings for this workflow. If OBS saved MKV, use OBS File → Remux Recordings to make MP4 first.
  4. Record in OBS and press F9 at moments you want to keep. You can change the hotkey in Settings.
  5. After recording, open Clip, adjust the time before and after each mark, and choose a reel, separate clips, or both. Double-click a recording to review and edit its marks.
  6. Review your exported files before selecting originals in Clean. Removal sends selected files to the Windows Recycle Bin.

FFmpeg and FFprobe are bundled. Leave room for both the original recordings and exported files. The player and editor export still need final installer checks before this candidate is released.
