FramingCalc

Source selection

FramingCalc starts from a camera source. Select the camera brand, model and internal recording resolution, or choose CUSTOM to enter a source resolution manually.

The Source lens factor applies the selected squeeze factor before any further calculation. A 1x value is spherical; 1.33x, 1.5x, 1.8x and 2x are treated as anamorphic source factors.

Viewer modes

Camera

Shows the full sensor with native values and the selected output format overlaid as a crop reference.

Editing

Fits the complete sensor image into an output-based editing format so editorial can work without unnecessary rescaling.

FDL

Shows Source Canvas, Derived Canvas, framing decision and protection as they will be represented in an ASC FDL file.

Frameleader

Generates a white framing chart with project, DoP, source, active area, safety margin and technical references.

Output, active area and safety margin

Output format defines the target resolution. It can match the source, use a preset such as HD/UHD/DCI, or be custom.

Active area aspect ratio defines the useful framed area. It can match the source, match the output format, or use a fixed aspect ratio.

Safety margin expands the protected area around the active frame. Resulting values are rounded to usable even pixel dimensions.

Exports and FDL workflow

• Export PNG exports the current viewer. Camera mode uses the source size; editing mode uses the calculated editing format; Frameleader exports the chart at source size.
• Technical Sheet PDF creates a printable document with camera and editing references.
• Export FDL is available in FDL mode and writes an ASC FDL document.
• Import FDL can display external FDL files. If the file was generated by FramingCalc, source data can be synced back into the tool.
• Export FDL Source creates a source-only FDL from camera mode.

Calculation criteria

• The source aspect ratio is never changed.
• Anamorphic lens factor is applied before downstream calculations.
• The active area is driven by aspect ratio and safety margin.
• The editing format must cover the source and respect the selected output constraints.
• If the source is below the required output, the viewer marks it as out of range.
