# Replay Controls

See [Replaying Saved Sonar Files](/c/sonarview/replaying-saved-sonar-files.md) for the general description, but here we discuss the Omniscan-specific Export controls.

SonarView for Omniscan supports 4 export formats (XTF and SL2):

* svlog: (re)export as an svlog. This is useful for trimming a subset of the file.
* [Sidescan XTF](https://www.exail.com/resources/knowledge-center/xtf-file-format-information): An open source sidescan format containing both imagery and positional data for sidescan mosaicking. Useful with software like DeepView and SonarWiz.
* SL2: A Lowrance format containing both imagery and positional data for sidescan mosaicking. Recommended for use with ReefMaster.
* [GeoTIFF](https://www.ogc.org/standards/geotiff/): Georeferenced raster image format of the flattened sidescan mosaic. This can be opened in an image viewer or in non-hydrographic GIS software like QGIS.
