Focus, framing, lenses and exposure on set
Depth of Field
Near and far focus limits, hyperfocal distance, and the stop that holds two subjects in focus.
35mm f/2.8 @ 3m, Super 35 → 2.57m to 3.61m
Field of View
Horizontal, vertical and diagonal angle of view, and frame coverage at any distance.
50mm on full frame → 39.6° horizontal
Focal Length Match
Find the lens that gives the same horizontal view on a different sensor width.
50mm FF → Super 35 → 34.6mm
Exposure
Enter a stop change and see the iris, shutter angle, ISO or ND that compensates for it.
+1 stop at T2.8, 180° → T4, 90°, ISO 400 or ND 0.3
Close Focus
Magnification, effective aperture and light loss for extension tubes; new close-focus distance for diopters.
50mm + 25mm tube @ f/2.8 → 0.5×, f/4.2 effective
Anamorphic
Desqueezed aspect ratio and horizontal-equivalent spherical focal length for any squeeze.
2× on 4:3, 40mm → 2.67:1, 20mm equiv.
Data/DIT · 3
Storage, record time, bitrate, RAID and uploads
Data & Storage
Solve for file size, record time or bitrate, from codec presets or a camera's published data rates.
1hr @ 50Mbps → 22.5 GB
Upload Time
Estimate how long a file takes to upload, with a best-to-worst-case range.
5GB @ 100Mbps → 6m 40s
Storage/RAID
Compare usable capacity and fault tolerance across RAID 0, 1, 5, 6 and 10 for your drives.
8 × 16TB, RAID 6 → 96 TB usable
Editorial · 6
Timecode, retiming, aspect ratios and film footage
Aspect Ratio
Pixel dimensions for any aspect ratio, anamorphic desqueeze, and fit or fill to a delivery size.
1920×1080 → 21:9 → 1920×823
Speed Change
Playback speed and running-time change when footage plays at a different frame rate.
48 fps → 24 fps → 50% speed
Target Length
The exact retime percentage that fits a clip into a target duration.
2:30 → 2:00 → 125% speed
Timecode Calculator
Add, subtract, multiply and divide timecode, and convert between timecode and frames.
01:23:45:12 + 00:15:30:08 → 01:39:15:20
Film ↔ Time
Convert film footage to running time and back, for ten formats from Super 8 to 15-perf IMAX.
400ft Super 16 @ 24fps → 11m 6s
Time Lapse
Set the intervalometer: shot interval, frame count and speed-up for any time-lapse.
2 hours → 10 s @ 24fps → Shoot every 30 s
