After configuring the required export parameters, click the Export button to start the process.
Note
The Export button can be inactive if
- there are no archive files by the selected cameras for the specified period. Also, the corresponding message is displayed above the button in such a case:
- there is not enough space to save the exported files (see The size of the exported file).
After clicking the Export button, all elements of the utility configuration will become inactive, and the bar of export progress will be displayed at the bottom of the utility window. The percentage of export will be displayed in the window title and next to each camera name.
It is possible to stop export at any time by clicking the Cancel button.
When the AviExport utility window is minimized during export, the progress is displayed in the smaller window:
To expand the AviExport utility window, click the More button.
Export result
After export is completed, a file of the specified type will be created in the specified folder—for example, AVI file with the name in the "camera_id_YYYY-MM-DDTHH-MM-SS.avi" format, or a VIDEO folder containing archive files if export is performed without conversion.
Export features:
- The duration of the exported file may be longer than the specified export period. This is because the export starts with the last reference frame before the specified time period. For example, if you export 30 seconds of recording, the resulting file may be 31 seconds long.
- If there are special characters in the camera name, such as \, /, :, *, ?, |, ", they will be replaced by underscore _ in the file name. If videos have captions with camera name, it will be displayed with special characters (see Setting captions export parameters).
If video resolution was changed during export, then the exported file will be divided into several parts containing archive intervals with different resolutions. If the UseFfmpegConcat registry key is enabled to merge such parts into one file (for details, see Registry keys reference guide), the exported file will be in MKV format regardless of the selected container type. If only codec (not the resolution) was changed during export, then the exported file won’t be divided into parts. The change of codec and resolution can be caused by selection of different streams for recording upon alarm and continuous recording—see Configuration of multistream video.
- If you select several cameras for export and at least one of them has no recorded archive in the specified time interval, the files will be successfully created, but the export will end with the "Export failed" message. The error occurs because the cameras without archive didn’t generate the resulting file.
