How to Plan Storage for Video Projects and Avoid Running Out

Objective

You will be able to estimate the space a video project needs, decide which drive holds which files, and keep your computer fast and your work safe.

Before you start

• A computer you edit on
• Some idea of how much footage you shoot per project
• Willingness to spend a few minutes on setup before you start editing

Overview

Video files are large, and a project creates more of them than most people expect. The footage you shot is only the start. The editor also makes preview files, caches, audio files and exports. A drive that looked half empty can fill up in the middle of an edit, which often ends in failed renders, stuttering playback or lost work.

Planning storage is simple arithmetic plus a few habits. You work out roughly how much space a project will use, decide where each kind of file lives, and clear space on a schedule. This takes less time than recovering from a full drive.

The numbers differ widely between cameras, phones and settings, so this guide shows you how to measure your own, rather than quoting figures that may not match your gear.

Step-by-step

1. Measure how much footage you really shoot

   Look at your last three projects. For each one, check the size of the folder that holds the original footage. Write down the size and the length of the finished video. Divide to find a rough ratio, such as how many gigabytes of raw footage you keep for each finished minute.

   This ratio is more useful than any general rule, because it reflects how you shoot. Someone who records long single takes will have a very different number from someone who films many short clips.

2. Know what else a project creates

   Besides source clips, an editing project can produce several other kinds of files. Cache or render files store previews so playback is smooth. Proxy files are small copies of heavy footage that make editing easier on slower computers. Exports are the finished videos, and you will often make more than one version. There may also be project files, audio recordings, graphics, music and backups.

   Most of these are not tiny. Caches in particular can grow quietly in the background. Find out where your editor stores them. Look in its settings for a cache or temporary files location, since the name and place vary by program.

3. Add a safety margin to your estimate

   Take your footage estimate and add room for caches, proxies, exports and backups. A cautious approach is to plan for noticeably more than the raw footage alone, then adjust once you see real numbers from your first project. If you are not sure, over-estimate. Spare space is cheap compared with a failed render.

   Also leave free space on the drive itself. Computers slow down and behave badly when a drive is almost full, and some editors will warn or stop. Do not plan to fill a drive to the edge.

4. Decide which drive holds what

   If you have only one drive, you can still organize, but if you have more, separate the roles. A common approach is to keep the operating system and editing software on the internal drive, and keep footage and project files on another drive that has plenty of room. Caches and previews often work best on a fast drive.

   What matters is that the drive can supply data quickly enough for smooth playback. Solid-state drives are generally much faster than traditional spinning hard drives, and external drives vary in speed depending on the drive and connection. If playback stutters when footage is on an external drive, the drive or its connection may be the bottleneck.

5. Build a simple folder structure

   Create one main folder per project, and put the same subfolders in each: footage, audio, graphics, project files and exports. Name them in a way you will understand in a year, such as date, then topic. A consistent structure means you can find things quickly and back up one folder instead of hunting.

   Keep everything for a project inside its folder. Scattered files across your desktop, downloads and several drives are the main cause of missing media warnings later.

6. Use proxies or lower-resolution previews when space or speed is tight

   Some editors can create proxy files, which are lighter copies used for editing while the full-quality originals are used for the final export. This can help with slow playback, but proxies take space as well. Check how much space they use and delete them when the project is done, since they can be made again.

   Only use proxies when you need them. If your computer plays your footage smoothly, there is no need to add more files.

7. Clear caches on a schedule

   When a project is finished and exported, clear its cache and render files. Many editors have a command or a setting for this. Check the editor's help for the right place, as it varies. Do not delete your source footage or project file as part of cache cleaning.

   If you cannot tell whether a folder is safe to delete, leave it alone and look it up first. Deleting the wrong folder can cost you work.

8. Back up before you delete anything

   Storage planning includes copies. A common guideline is to keep more than one copy of anything valuable, with at least one copy on a different device. At minimum, keep your source footage and final project file in two places before you clear space on the working drive.

   External drives can fail, so one copy on a single external drive is not a real backup. Cloud storage is another option, but upload time and cost depend on your internet connection and plan.

9. Archive finished projects

   When a project is done, decide what to keep. Typically that means the final export, the project file and the original footage if you may need it again. Move that folder to a long-term location and remove the working copy to free space. Delete caches, proxies and test exports.

   Write a short text note in the folder saying what the project was and which software version made it. Future you will be glad of it.

Examples

Common mistakes

• Planning only for the raw footage. Caches, proxies and exports add up. Include them in your estimate.
• Filling the drive to the limit. Almost-full drives slow down and can cause errors. Keep real free space.
• Leaving files scattered. Footage on the desktop, music in downloads and exports elsewhere is how projects lose media. Keep each project in one folder.
• Treating one copy as a backup. If a single drive fails, everything is gone. Keep another copy on a separate device.
• Deleting unknown folders to free space. Some folders hold things you need. Find out what a folder is before you remove it.

Best practices

• Check free space before every shoot day and every big export.
• Name folders with a date first so they sort in order.
• Keep a habit of cleaning caches right after each export.
• Label external drives physically so you know what is on them.
• Review your storage plan every few months, because cameras and settings change.
