# Basic Usage & Exporting

The App container consists of two panes.  The large pane on the left is for presentation of the loaded clip and for scrubbing along the clip using the scrub slider at the bottom.  The timestamp in the bottom left corner indicates the current playing position in the recording time frame.

The right pane contains the controls for the various tools with the active tool being selected from the top pull down menu.  In addition, transport controls for Play/Stop and Stepping are available at the bottom of this pane.  During playback the playback speed can be adjusted by using the playback multiplier stepper.

Clips are opened from the Main menu (File -> Open) or from the Info tab by pressing Open file.

Some of the tools generate a graphical overlay on the clip (e.g. the Tracking tool object tracking rectangle) which will be included in the exported video.  In addition some tools present a chart overlay for visualising the measurements.  The chart graphic overlay cannot be exported but the numerical data underlying the chart can be exported as a CSV file for analysis and plotting in the users application of choice, e.g. Excel.

Various keyboard controls are available for managing playback. Spacebar toggles between Play and Stop. Left and Right cursor keys are used for frame by frame stepping. Up and Down cursor keys can be used to adjust playback rate.

## Exporting Videos and CSVs

The clip, including any image processing applied by the tools, may be exported in ProRes format for viewing outside the toolbox.  In addition any charts that have been opened in any of the tools may have the underlying data exported as a CSV file.  The metadata in the original file will not be embedded in the exported clip, however if the metadata has been loaded in the [Metadata tab](https://docs.freeflysystems.com/products/products/ember-camera/ember-scientific-toolbox-app/metadata-tool) then accompanying CSV files will be generated which contain the parsed IMU data.  

To setup for export select the **Export** tool.  Scrub or play to the point where export should begin and press **In**, then scrub or play to where export should finish and press **Out**.  Note that if the Tracking, Rotation or Tachometer tool is active then the In time will be set to the point where the measurement was initiated and cannot be changed.

If no export folder has been selected then press **Export folder**… and browse to a folder where the clips should be exported.

Press **Start** to begin export and wait until finished.
