Nature Recording Workflows and Production Checklists

Workflows and checklists used to ensure consistent recording quality during field recording and post-production. The procedures documented here help maintain reliable capture conditions, consistent technical settings, and predictable editing results across all projects.

These workflows support the production of wildlife films, soundscapes, and macro nature photography published throughout this site.

Video Recording

These checklists guide field recording sessions and ensure that all technical and documentation steps are completed. Locations are recorded using Québec Sauvage field reports and later exported to document exact recording sites for soundscapes and animal behavior footage.

Soundscapes

I capture a short iPhone video showing the microphone setup and surrounding environment to document the recording conditions if soundscapes are flagged as copied.

Audio

  • iPhone in airplane mode, screen off
  • Anker battery placed at maximum cable distance
  • No nearby high-level sound sources
  • ORTF WS correctly aligned (cables exit left)
  • Remain at least 20 m away from microphones while recording
  • Minimum 15 minutes continuous recording

Video

  • Format set to 29.97 fps 4.1K
  • Polarizing filter mounted
  • Manual focus confirmed
  • Rode VideoMic NTG audio level checked
  • Multiple angles and focal lengths captured

Animals Close-Up

  • Format set to 29.97 fps 4.1K
  • Camera mounted on tripod
  • Rode VideoMic NTG audio level checked
  • Shutter speed and aperture optimized

Notes

  • An active iPhone may cause electrical crackling in the sound recording. It’s very important to keep the iPhone turned off or far away from the Behringer C-2 microphones.
  • Moving at least 20 m away from the microphones prevents footsteps or other movement from being captured in the recording.
  • A minimum recording length of 15 minutes allows unwanted sound events to be removed later without leaving the final recording too short.
  • Recording consistently in 29.97 fps 4.1K helps build a standardized library of source footage over time while preserving enough resolution to adjust framing later in post-production.
  • Frame rate may be set to a multiple of 29.97 fps when slow-motion adjustments are anticipated during post-production.

Render Videos - Soundscapes

I use DaVinci Resolve Studio (DR) for all video and audio editing. I produce the following versions: 4K (@muuuh VOD), 1080p (@muuuh broadcast), and optionally an audio-only export for the Spotify channel. The rendered soundscape videos (VOD) are listed in the Soundscapes section.

Checklist before Render

  • Resolution set to 3840 × 2160
  • Frame rate set to 29.97 fps
  • Total length confirmed (1 hr − 4 sec)
  • Audio normalized to ITU-R BS.1770-4 (−28 LKFS / −2 dBTP)
  • Saturation, highlights, and contrast reviewed
  • All video and audio cuts reviewed

Settings DR Render → MASTER

  • Container: QuickTime
  • Codec: Apple ProRes
  • Type: Apple ProRes 422 LT
  • Resolution: 3840×2160
  • Frame rate: 29.97 fps
  • Audio: Linear PCM, 48 kHz, 24-bit

Settings DR Render → Audio Only

  • Format: Wave
  • Codec: Linear PCM
  • Sample rate: 48 kHz
  • Bit depth: 24-bit

Final Renders with ffmpeg

In DR, I render only the MASTER. Final publishing renders are generated with ffmpeg from the MASTER file.

Render MASTER → 4K YT VOD & 4K Stream

caffeinate -dims ffmpeg -i FILENAME-MASTER.mov \
  -c:v libx264 -preset medium \
  -b:v 25000k -maxrate 25000k -bufsize 50000k \
  -pix_fmt yuv420p \
  -profile:v high -level 5.2 \
  -g 60 -keyint_min 60 \
  -c:a aac -b:a 256k \
  FILENAME-4K.mp4

Main render. This version is generated on a second computer, allowing my main workstation to remain available for video editing or for rendering a new MASTER.

Render MASTER → 1080p STREAM

caffeinate -dims ffmpeg -i FILENAME-MASTER.mov \
  -vf "scale=-1:1080" \
  -c:v libx264 -preset veryfast \
  -b:v 6800k -maxrate 6800k -bufsize 13600k \
  -pix_fmt yuv420p \
  -g 60 -keyint_min 60 \
  -c:a aac -b:a 256k \
  FILENAME-1080p.mp4

Fast render (30 minutes). Used for UHD broadcast.

Render MASTER → 4K

caffeinate -dims ffmpeg -i FILENAME-MASTER.mov \
  -c:v libx264 -preset medium \
  -b:v 40M -maxrate 40M -bufsize 80M \
  -pix_fmt yuv420p \
  -profile:v high -level 5.2 \
  -c:a aac -b:a 192k \
  -movflags +faststart \
  FILENAME-4K.mp4

Optional high quality render with faststart header.

Render Shorts - Animal Behavior

The timeline uses 1080 × 1920 vertical, 29.97 fps, with “Centre crop with no resizing” to avoid scaling artifacts while preserving the camera’s original pixels. This allows limited vertical reframing (≈165 px) and substantial horizontal adjustment to follow the subject. Short-form animal behavior clips produced with this workflow are listed in Videos.

Settings Render 1080p → YouTube

Macro Photography - Focus Shifting

Jardin Botanique de Montréal - Red Clover (Trifolium pratense)

Tap image to enlarge

Focus shifting is a macro photography technique used to extend depth of field by capturing multiple images at different focus distances and combining them later in post-processing. This technique is particularly useful in macro photography where depth of field becomes extremely shallow at high magnifications. Focus shifting only works under zero-wind conditions, since even small movements between frames can ruin the stack.

The following settings are used for macro photography with the NIKON Z8 and the NIKKOR Z MC 105mm lens. The distance to the subject is read directly from the lens distance display.

At 29 cm (≈1:1 macro)

Aperture Depth to Cover Step Size Approx. Shots
f/11 2 cm 3 60–80 shots
f/11 5 cm 3 120–150 shots
f/5.6 2 cm 2 120–160 shots
f/5.6 5 cm 2 250–320 shots

At 50 cm (≈1:2 to 1:2.5)

Aperture Depth to Cover Step Size Approx. Shots
f/11 2 cm 3 20–25 shots
f/11 5 cm 3 45–55 shots
f/5.6 2 cm 2 35–45 shots
f/5.6 5 cm 2 70–90 shots

Lighting

I block direct sunlight and illuminate the subject primarily with a dimmed Ulanzi LT028 (40W), adding an optional Ulanzi RGB video light for backlight.

I target ISO 100 for the cleanest files and choose f/11 or f/5.6 depending on available light to keep shutter speed reasonably fast (typically faster than 1/5 s).

About the Photo: The example image shows Red Clover (Trifolium pratense). This photograph illustrates the type of macro photography image produced using the focus-shifting workflow described above.

Editing Affinity Photos

Parc national de l'Île-Bonaventure-et-du-Rocher-Percé - Northern Gannet (Morus bassanus)

Tap image to enlarge

I use Affinity Photo for photo editing and try to keep as few destructive steps as possible, since they can’t be changed later in the editing process. The final images are published in Photos.

Photos that qualify as key portfolio images — suitable for desktop backgrounds, full-width banners, or print — are exported at 6000 × 4000 px. All other images, intended primarily as documentary photos accompanying species pages or habitat/park descriptions, are exported at 3000 × 2000 px.

About the Photo: The example image shows a pair of Northern Gannet (Morus bassanus) touching bills during courtship. This photograph illustrates the type of wildlife image produced using the editing workflow described above.
