1. CD—the files of this size are suitable for recording on a CD disk (670 MB).

2. DVD—the files of this size are suitable for recording on a DVD disk (4.7 GB, for AVI file—2 GB).

   If you select CD or DVD, and  and the size of the archive that needs to be exported is larger than the disk size, the recording goes as follows: the part of the exported archive is recorded on the inserted disk. Then the disk drive opens for the next disk to be inserted. After you insert a new disk, the next part of the archive is recorded on it. And so on, until all video recordings are exported.

3. Divide by alarms—division into files is performing performed if there are time intervals between the records. If the recording is continuous, alarms are not considered.
4. Specify the volume size in megabytes in the text field. The AVI file must not be set to more than 2048 MB. If you set a larger value, the size of the resulting files will still not exceed 2 GB.

   Different containers have their own metadata, which increases the size of the volume (export file). If you export to an EXE file, this file must have space for the player. Thus, if the specified size of the exported file is smaller than the minimum required file size, the export completes with an error that specifies the minimum required file size. The player size, if exported to EXE, is about 18 MB. Minimum container size: -AVI: 1 GOP + 7% of the size of 1 GOP-MP4: 1 GOP + 3 MB -MKV: 1 GOP + 1 MB + 1% of the size of 1 GOP -FLV: 1 GOP + 1 MB + 2% of the size of 1 GOP -ASF: 1 GOP + 3 MB + 3% of the size of 1 GOP For example, when you export to an ASF container in EXE format, the minimum volume size at GOP = 1 MB is 1 MB + 3 MB + (3% * 1 MB) + 18 MB = 22.03 MB.

When you change the period (see General export settings of export), the disk space required for saving the specified period of archive is automatically calculated and displayed:
