<!-- skill: GoPro Action | version: 1.0.0 | description: Protune, Hypersmooth, mounts and media workflow for GoPro | category: Video & Design -->
## Instructions
- Shoot 4K30 or 5.3K30 for detail, 4K60/120 for slow motion, 24fps only for cinematic narrative with motion blur.
- Enable Protune: Color Flat, Sharpness Low, ISO Min 100 / Max 800 daylight (1600 max night), EV -0.5 to protect highlights.
- Set White Balance to native (5500K day, 3200K indoor) instead of Auto to avoid color shifts mid-clip.
- Choose Hypersmooth: On for walk/bike, Boost for run/shake, Off + gyro in post for horizon lock or reframing 360.
- Use lens mods correctly: Max Lens Mod for 155-degree + HorizonLock, ND 16/32 for 180-degree shutter (1/48 at 24fps).
- Mount securely: check thumb-screw tightness, use tether on helmet/chest, test J-mount angle with phone preview.
- Format media routine: Samsung Pro Endurance / SanDisk Extreme 256GB max, format in-camera before every shoot day.
- Manage batteries: carry 3+ Enduro, keep warm in winter inside jacket, swap at 20%, charge via dual charger overnight.
- Expose with histogram: keep highlights left of clip, use front-screen blinkies, lock exposure on snow/sand scenes.
- Record audio with Media Mod or wireless lav, set windsock on, capture 10s room tone for edit fill.
- Back up with GoPro Player + Quik: offload via USB-C reader, rename `YYYYMMDD-location-camA-001.mp4`, checksum copy.
- Maintain housing: rinse after salt/sand, inspect door seals, replace cracked mounts, update firmware before trips.
## Examples
- MTB follow: 4K60 Wide, Hypersmooth Boost, Protune Flat, ND16, chest mount + tether, EV -0.5.
- Vlog walk: 5.3K30 Linear + HorizonLock, Media Mod lav, Auto WB locked 5500K, quick-capture enabled.
- Surf: 4K120 Narrow for 4x slow, Waterproof housing + floaty, rinse + dry seal after session.
## Workflows
### 1. Shoot-day routine
1. Format cards in-camera, set date/time/GPS, test record 10s + playback.
2. Mount + tether check, lens clean with microfiber, ND select by histogram.
3. Shoot with 5s handles, call shot + slate for multicam sync.
4. Swap battery at 20%, offload at lunch to SSD with checksum.
### 2. Protune grade prep
1. Import flat clips, apply GoPro LUT at 70% + manual contrast.
2. Sharpen in post (Unsharp 60/1.0), denoise Neat Video if ISO 1600+.
3. Stabilize gyro footage in Player, export ProRes for edit.

## Tools
- GoPro Hero 11/12/13, Max Lens Mod 2.0, ND pack (8/16/32), Media Mod, Enduro batteries.
- Mounts: Chesty, helmet adhesive + clamp, suction cup, 3-way pole, floaty, dive housing.
- Software: GoPro Player (gyro), Quik, DaVinci Resolve, ExFAT Checker, checksum copy tool.
## Advanced
- Shoot 8:7 full sensor for vertical + horizontal reframing from one take, punch to 9:16 without reshoot.
- Use Labs firmware: motion-activated record, QR presets for trail/travel/vlog one-scan setups.
- Night lapse: 4K Night Lapse, interval 10s, ISO 100-800, Protune RAW stills for star trails stacking.
- Sync multicam with timecode slate + audio clap, align in Resolve by waveform then refine by gyro data.
## Documentation
- GoPro manuals: Protune chart, Hypersmooth modes, Max Lens Mod FOV table.
- Exposure: 180-degree rule, histogram reading, ND selection chart by EV.
- Internal: mount inventory, battery cycle log, firmware version tracker.
### QA checklist
- [ ] Protune Flat + Sharp Low, WB locked (not Auto), EV -0.5 daylight.
- [ ] Hypersmooth matched to motion (On walk / Boost run / Off gyro-post).
- [ ] Mount torqued + tethered, lens clean, histogram no right-wall clip.
- [ ] Cards formatted in-camera, batteries 3x charged, time/GPS synced.
- [ ] Offload checksummed, renamed YYYYMMDD-site-camA, proxy for edit made.
