How much video storage does a business need?

There is no fixed amount of video storage that every business needs. Storage requirements depend on the size of your existing video library, the files you retain, and how quickly you add new content. This article explains how to calculate your video storage requirements and plan capacity using file sizes, bitrate, retention periods, and expected library growth.

How do you calculate video storage requirements?

Video storage requirements start with the amount of data a business needs to retain. For an existing library, the simplest starting point is the combined size of all video files that will remain in storage. Businesses using a video hosting platform should begin with the storage currently used by their hosted video library.

Future requirements also need to account for new content. If a business currently stores 500 GB of video and adds approximately 50 GB each month, its library could grow by another 600 GB over a year. That would produce approximately 1.1 TB of stored video before accounting for deleted files, additional versions, or other changes to the library.

Businesses with predictable production schedules can estimate storage growth from the number and average size of new files. When production varies significantly, recent monthly or quarterly growth can provide a more useful baseline.

What affects the amount of video storage you need?

Two businesses producing the same number of videos can have very different video storage requirements. The amount of data each file consumes depends on how the video is created, encoded, and retained.

The main factors include:

• Video duration. Longer videos generally require more storage when other encoding settings remain the same.
• Bitrate. Higher bitrates use more data for each second of video, increasing the resulting file size.
• Resolution. Higher-resolution video can require larger files, although the final file size also depends on bitrate, codec, and other encoding settings.
• Frame rate. Higher frame rates can increase the amount of visual information encoded in a video.
• Codec and compression. Different codecs and encoding settings can produce different file sizes from similar source footage.
• Number of versions. Source files, edited masters, exports, and other versions can all contribute to the storage used by one piece of content.
• Library growth. Regular video production increases storage requirements even when individual file sizes remain consistent.
• File retention periods. Keeping footage and finished videos for several years creates different capacity requirements from regularly removing old assets.

How does bitrate affect video file size?

Bitrate measures the amount of data used for each second of video. It is one of the most useful inputs for estimating how much storage a video file will require.

A simplified calculation is:

File size = bitrate × duration

The bitrate must be converted into the appropriate units when calculating the final result. For example, a video encoded at 8 Mbps uses approximately 1 MB of data per second because there are eight bits in one byte. At that bitrate, one hour of video would require roughly 3.6 GB before accounting for audio and other overhead.

Approximate storage at different video bitrates looks like this:
 

These figures are estimates. Actual file sizes depend on the video and audio encoding settings used.

How much storage does 1080p video need?

There is no single storage requirement for 1080p video because resolution does not determine file size on its own. Bitrate, frame rate, codec, duration, and encoding settings also affect the amount of data stored. For example, one hour of 1080p video encoded at 5 Mbps would use approximately 2.25 GB for the video stream. Increasing the bitrate to 8 Mbps would raise that estimate to around 3.6 GB.

A business storing 100 hours of 1080p video could therefore require hundreds of gigabytes even before source footage, alternative exports, or future content are included. The bitrate of the files being retained provides a more reliable basis for calculating storage than assuming that every 1080p video has a similar file size.

How much storage does 4K video need?

4K video can require substantially more storage because it is often encoded at higher bitrates than lower-resolution content. The exact file size still depends on the codec and encoding settings. At a video bitrate of 25 Mbps, one hour would require approximately 11.25 GB of storage. One hundred hours at the same bitrate would require roughly 1.13 TB.

Production files can be considerably larger. A business retaining high-quality camera originals or editing masters may therefore consume storage much faster than one storing compressed versions prepared for online delivery.

This distinction is particularly important when estimating storage for video production. The files retained by the production team may have very different video storage requirements from the finished videos published to viewers.

Do source files and finished videos both count towards storage?

Every video file retained by a business contributes to its overall storage requirement. A single finished video can therefore represent several stored files across the production and publishing workflow.

A team might retain the original camera footage, an editing master, a final export, and the version uploaded for publication. Additional language versions, revised edits, or alternative formats can increase the total further.

The storage requirement for the project is the combined size of the files the business chooses to keep. This is why retention decisions can have a large effect on capacity. A team that retains every original recording indefinitely will accumulate storage differently from one that keeps final masters and removes unnecessary production files after a defined period.

How should businesses plan for video library growth?

Current storage usage provides the starting point, but capacity planning also needs to account for how quickly the video library is growing.

Consider a business with 800 GB of existing video. It produces around 60 GB of new files each month and expects to retain all of them for at least the next year. Over 12 months, those new files would add approximately 720 GB. The video library would reach roughly 1.52 TB if nothing were removed. If production increased to 90 GB per month during the following year, another 1.08 TB could be added. The same library could then exceed 2.5 TB.

Tracking monthly storage growth gives businesses a way to anticipate when their existing capacity may become insufficient. Production plans, new teams, additional markets, and longer retention periods can then be incorporated into future estimates.

How do file retention periods affect video storage requirements?

File retention periods determine how long videos continue to use storage capacity. Businesses that produce videos regularly can accumulate large libraries when files are kept indefinitely.

Different files may have different retention periods. Raw production footage might be removed after a project is completed, while final masters, training content, or reusable brand assets may be kept for several years.

A file retention policy can define which videos are kept and when they can be archived or removed. If a business adds 100 GB each month and regularly removes older files, its storage requirements will grow more slowly over time.

Should businesses leave spare video storage capacity?

Businesses should plan enough capacity to accommodate expected library growth between storage reviews or plan changes. The appropriate amount depends on how predictable video production is.

A team with a consistent publishing schedule may be able to forecast growth accurately from previous months. Businesses with seasonal campaigns, major events, acquisitions, or rapidly expanding video programmes may experience larger changes over shorter periods.

Regular storage monitoring can show whether actual growth is following the forecast. Teams can then revise their capacity estimate as production volumes, retention policies, and file sizes change. Regular storage reviews also allow businesses to update their capacity plans as the video library grows.

How is video storage different from bandwidth?

Video storage measures the amount of capacity used to retain video files. Bandwidth measures the data delivered when viewers stream those videos.

A 5 GB video occupies approximately 5 GB of storage while it remains on the platform. If the video is watched repeatedly, its stored file size does not increase simply because more people view it. The additional viewing contributes to delivery bandwidth. Businesses planning hosted video therefore need to consider both figures separately.

How much video storage does Cinema8 provide?

Cinema8's video hosting platform includes video storage across its hosting plans, with capacity increasing for businesses managing larger libraries. Current storage allowances include 2 GB on Free, 100 GB on Starter, 500 GB on Pro, 2 TB on Pro Plus, and 5 TB on Business. Enterprise plans provide tailored capacity starting from 10 TB of storage.

Storage is separate from the monthly bandwidth included with each plan. This allows businesses to compare the size of their hosted video library with the amount of content they expect to deliver to viewers. Businesses can select a plan based on their current library and expected growth, then monitor how their requirements change as more content is added.

Planning video storage for your business

Video storage requirements depend on the files a business keeps and how its library changes over time. File size, bitrate, production formats, additional versions, retention periods, and monthly growth all contribute to the capacity required.

Start with the size of your existing library, calculate how much video you add over a typical month, and account for the files you expect to retain. This provides an estimate that can be updated as production changes.
