SplitShot

SplitShot is a local-first desktop app for competition shooting video analysis, timing, scoring, multi-angle composition, metrics, and finished-video export. Your projects and media stay on your computer.

Get SplitShot

Download the package for your platform from Releases:

• macOS: open the DMG and drag or open SplitShot as prompted by macOS.
• Windows: run the installer, then open SplitShot from the installed app entry.
• Linux: download the AppImage, make it executable if your desktop does not do so automatically, then launch it.

First Project

1. Open Project and create a project in an empty folder, or open a folder that already contains project.json.
2. In Media, add a stage and import its primary video. SplitShot keeps imported media in the project Input folder.
3. Run ShotML to find a start beep and likely shots, then use Splits to correct the timeline.
4. Add official match context in Project and finish the run in Score when needed.
5. Use Compose, Trim, Markers, Overlay, and Review to prepare the presentation.
6. Check Metrics, choose output settings in Export, optionally configure In / Out, then use Queue to render the stage or a combined match video.

The left rail is ordered for that workflow: Project, Media, Compose, Trim, Score, Splits, Markers, Overlay, Review, Export, In / Out, Queue, Metrics, ShotML, and Settings.

Features

• Work locally with stage footage, projects, and exported video.
• Detect start beeps and likely shots, then refine every timing event manually.
• Import PractiScore context or score a run directly in SplitShot.
• Compose added video or still media and align it with the primary recording.
• Add timer, shot, score, review-text, and marker overlays that match the preview and export.
• Review timing and scoring metrics, then render individual stages or one combined file.
