Exporting to a File

Overview

The export feature in Keyframe Pro allows users to easily convert an edited source or timeline into a standalone media file (.mp4 format). Using the export options, a user can specify the output resolution, profile, quality, viewer layout and whether or not to include annotations.

Note: Keyframe Pro requires ffmpeg for export. ffmpeg is an open-source command line tool to convert multimedia between formats.

Installing FFmpeg

FFmpeg can be downloaded as a pre-built binary, built directly from the source code or installed using Homebrew (macOS). This guide will describe installing the pre-built binaries from Zerano FFmpeg (Windows) and FFmpeg Mac (macOS).

  1. Windows - Download the latest FFmpeg 64-bit Static build from Zerano FFmpeg
    macOS - Download the latest FFmpeg binary from FFmpeg Mac
  2. Extract the contents of the zip file to a location on your harddrive (e.g. D:/ffmpeg)
  3. Launch Keyframe Pro and open the Preferences dialog from the main menu (Edit->Preferences)
  4. Select the Export tab
  5. Press the Browse... button under FFmpeg Path
  6. Navigate to the extracted directory and select ffmpeg.exe (Windows) or ffmpeg (macOS)
    Note: On Windows, ffmpeg.exe is found in the bin directory


Export to File

A timeline or source can be exported to a standalone media file (.mp4) using the Export dialog.

From the main menu select File->Export:

Note: The export process is applied to the timeline or source in the primary viewer unless the "Viewer Layout" option is enabled.

Export Settings

Output File

The path to the exported file.

Dimensions

The resolution of the exported file.

Profile

Standard defined sets of capabilities targeting specific classes of applications.

Quality

A trade-off between quality and time. The higher the quality, the longer the encoding time.

Preset

A trade-off between speed and file size. The faster the encoding, the larger the file size.

Annotations

Include annotations in the exported media file.

Viewer Layout

Export the A/B split viewer layout (if active). If this is disabled only the timeline in the A viewer will be exported.

Ignore Range

Export the entire timeline, ignoring the current range start and end times.


Limitations

The following list outlines the known limitations of the export process:

  1. Timelines composed of clips with different frame rates are not supported.
  2. For best results, the clips in a timeline should use the same video and audio formats.
