CMS Recorded video size requierments

Hi Team,

we are planning to install and integrate the CMS Recording server with our TP Platform, which already includes the CMS Core & Edge services.

We have 2 no's CMS Recording license ordered from Cisco and we are in a process to buy External NAS Server. But we have some concern regarding the space requirements, please share if anybody have any documents or any details regarding the same. 

Otherwise i can calculate myself if i can get an answer for >> How much space required to store 1 minute video call with 1472 kbps bandwidth??

what is the video file compression format??

is there any alert will generate by CMS Recording server if the storage become full.

Please share any document that explains the CMS Recording configurations.

in advance thanks for your valuable time and interest for replying my queries...

Best & Regards,

Nikhil Jayan

Hi Nikhil,

As per one of the links i referenced some time back  the size of 720p30 recordings ranges between 300MB to 800MB for 1 hour. In terms of budgeting it would be safe to assume 1GB per hour.

Recorder Config




I am looking for CMS recording data sheet in particular but i am unable to find such document on cisco site, can you guys help.

There is no recorder data sheet, just the one for Cisco Meeting Server. For recorder information, refer to the CMS data sheet and deployment guides. 

Whar specific information are you looking for?

In addition to Manish's comment on the recording the file size.

File format will be MP4.

Don't think CMS monitors the size of the NFS location, so the only alert sort of speak you might get is an error in the event log.

Dear all,


Is there any document form cisco that tell the size of file recording? and what the output recording quality?
this information was needed for recording storage purpose.


Thank you

It should be supported, go to your CUCM and look at the drop-down for devices.
