EdgeVis stores recordings in manageable segments rather than one continuously growing file. This article covers EdgeVis Mobile Encoder (Android), EVVR hardware encoders and EVVR Container.
Why are recordings split into files?
Segmentation supports targeted retrieval: you can obtain the files covering the period you need rather than transfer a much larger recording. This is useful over cellular, satellite and other constrained links. Segment size and duration vary by product, configuration and video content; a file boundary is not itself a recording gap.
Codec and container: what is the difference?
H.264 is a video compression format. Codec support depends on the source and configuration.
CSX is the native EdgeVis recording container for unencrypted footage.
CSXS is the encrypted recording container. The recording password is needed to open or extract it.
MP4 is a standard container used for exported footage that can be played outside EdgeVis.
A codec describes the encoded video; a container packages that video and associated information. An MP4 export does not necessarily mean the video has been re-encoded.
Does segmentation interrupt playback?
Sequential segments can be presented on a common timeline. Normal file boundaries do not indicate editing or missing footage. Check actual recording availability separately: combining files cannot recreate footage that was never recorded or was not retrieved.
Keep the recording context
Preserve the native files and associated recording structure when retaining footage. Keep recordings from different encoders in separate folders. When copying a recording disk, retain the complete folder structure, including archive and db folders, so that associated metadata remains available.
Can I export a selected period?
Yes. EdgeVis Media Manager supports timeline extraction, allowing sequential recordings to be exported for external review. Retain native recordings alongside exports when integrity verification or further examination may be required.
