How to merge media files into one using split screen feature


CaseGuard’s Split Screen feature merges up to 16 media files into one video for easier exporting, editing, or redacting. This feature is especially useful for merging multiple videos into one video of the same incident from different angles to ensure all Personally identifiable information is protected. Users can select from up to three templates to decide how their videos are displayed.

One use case for this feature would be if you have security footage from four different angles you need to combine it into one video to comply with a Freedom of Information Act request. Combining the four videos into one by using the Split Screen feature and performing redactions on one video instead of four will save time in redaction and export.

Additionally, users can add the audio file with closed captions of the 911 call with the footage of the incident in one split screen. Presenting the audio call alongside the crime scene is often praised by courts for enhancing transparency when introducing evidence.
