## How to use it
1. **Install FFmpeg once.** The first time, OneMacTools offers to install FFmpeg through Homebrew with one click.
2. **Drop a short clip.** Add the video you want to play with. Short clips of a few seconds work best for boomerangs.
3. **Choose the effect.** Boomerang plays forwards then backwards, Reverse plays backwards, and Loop repeats the clip.
4. **Set the repeats and sound.** Choose how many times it repeats, and whether to keep the sound for Reverse and Loop.
5. **Click Make.** The result is saved as an MP4, with the effect in its name, in a new dated folder in Downloads › OneMacTools. Watch it with the Preview (eye) button or Show in Finder. Your original clip doesn't change.

## Options
- **Effect:** Boomerang (the default) plays the clip forwards then backwards, like the camera effect. Reverse plays it backwards. Loop plays it again and again.
- **Repeat:** 1×, 2× (the default), 3× or 5×. How many times the boomerang or reversed clip plays. Loop always plays the clip at least twice.
- **Keep the sound (Reverse and Loop):** On by default. Reverse plays the sound backwards too; Loop repeats it. Boomerangs are always silent, like the camera effect.

## Tips
- Boomerangs work best with 1–3 seconds of simple motion: a jump, a toss, a clink of glasses. Trim the clip first.
- Reverse and Boomerang only take clips up to 2 minutes, because the whole clip has to be held in memory. Loop has no limit.
- Turn off Keep the sound for reversed clips. Backwards speech rarely sounds good.
- Looped clips make good website or presentation backgrounds. Mute them and compress them afterwards.
- Convert a boomerang to a GIF with Video to GIF if you need it to loop in a chat or document.
