The Export Table lists all the selected takes for export, their start and end frames, samples, sample rate, and other options. The Export Table is the same for all data formats except scenes and .fbx files. See Exporting options for scenes.
The top row is the All Takes Row. It lets you change the value of a given column for all files at the same time. Values for each file are clamped to their absolute minimum or maximum. For example, if you enter 30000 as the sample rate, the sample rate for all files is set to its maximum.
Displays the name of the file where each take is exported. You can rename the file using this field.
The Start and End time codes are expressed in the same time format as is shown in the Transport Controls. You can change the start and end to change the part of the take that you are exporting.
Displays the number of samples, which is calculated by multiplying the duration (based on the start and end) by the sampling rate. You can change the duration by changing the number of samples or Sampling Rate. This changes the End timecode.
The Sampling Rate field, by default, is set to the frame rate as shown in the Transport Controls, or the frame rate of the selected optical model (if exporting optical data). Changing the Sampling Rate changes the End timecode. Select Custom to use the adjacent Custom field to enter your own sampling rate.
