Archive Masters and Delivery Files: Keep Your Best Export

Objective

Create a high-quality master export, derive smaller delivery files from it, and organize and back up both so you can reuse your work later.

Before you start

• A finished edit
• Understanding of codecs and bitrate
• Some free storage space or an external drive

Overview

Most editors export once, upload the file and move on. Weeks later a client asks for a vertical version, a shorter cut or a version with new captions, and the only copy is a compressed file from a platform. Compressing a compressed file again makes quality worse each time.

The fix is to separate two kinds of exports. A master is the best version you can reasonably make, kept for the future. A delivery file is a smaller version made for one purpose, such as an upload or a client preview. You make the master once and create delivery files from it as needed.

This habit costs a bit of disk space and a few minutes at the end of each project. In return, you can reuse your work without rebuilding it from scratch, and you reduce the risk of losing the only good copy.

Step-by-step

1. Understand what a master is

   A master is a full-quality export of your finished timeline: the final picture, the final mix, at the full resolution and frame rate of the project. It is not meant to be small. It is meant to hold up under further conversion.

   The key idea is that you can always make a smaller file from a larger, cleaner one, but you cannot add back detail that was thrown away. When you keep a master, every later version starts from the best available source.

2. Choose a master format with lots of quality

   Look at the export options in your editor for a format intended for high quality or editing rather than small size. Many editors offer intermediate or mastering codecs that keep more picture information and are easier on the computer to decode, at the cost of big files. The names differ between programs, so check what yours offers and read the description.

   If your editor lacks such options, a very high bitrate export with a common codec is still a useful master. The point is to be clearly better than the files you deliver. Keep the project's full resolution, frame rate and color setup unchanged, and use stereo or the full channel layout of your mix.

3. Export the master first

   Make the master export once the edit is approved, before you make any delivery versions. Watch it through. Check the picture, check the sound, and check that it ends where it should. A problem in the master spreads into every version you make from it.

   This is a good moment to look for clipping in the audio and any flash frames or gaps in the video. Fix them in the project, then export again if needed. The master should be the version you would be happy to hand to anyone.

4. Make delivery files for each purpose

   Now list where the video needs to go. A video site needs a standard upload file. A social app might need a vertical or square version. A client may want a lighter preview. For each, set resolution, frame rate, codec and bitrate to suit the destination.

   Where possible, export delivery files from the project timeline rather than converting the master afterward, since a direct export is a single compression step. If you only have the master, converting from it is still better than converting from a previously compressed file. Platform rules change, so check the destination's current help page.

5. Name files so you can find them

   A good name tells you what the file is without opening it. Include the project, a short description, the version, and the type. For example: project-name_main-cut_v03_master.mov, or project-name_main-cut_v03_youtube-1080p.mp4. Pick a pattern and use it every time.

   Avoid vague names like final, final2 and really-final. Use version numbers and dates instead. Use lowercase letters, hyphens or underscores, and avoid special characters, which can cause trouble in some systems.

6. Organize folders by role

   Create a simple structure for each project. One folder for source footage, one for the project file and its autosaves, one for exports. Inside exports, separate masters from deliveries. This takes seconds and prevents mix-ups later.

   If you work with a team, agree on the structure once. People find files faster, and handoffs go more smoothly. For more on organizing before you start, see the guide on organizing footage before editing.

7. Back up the master in more than one place

   A single copy on one drive is not a backup. Drives fail, files get deleted by accident and laptops are lost. A common habit is to keep at least two copies on separate devices, with one stored somewhere else, such as cloud storage or a drive kept at another location.

   The master is often the most valuable file in the project, because it contains the finished result. Back it up before you delete any raw footage or clear space. Confirm the copy opens and plays. A backup you have never tested is a guess.

8. Decide what else to keep

   Not everything needs to be stored forever. Storage costs money, and clutter hides the files you need. Decide at the end of each project what is worth keeping.

   At minimum, keep the master, the project file, and any assets that cannot be replaced, such as original footage, recorded voiceovers, custom graphics and licensed music with its license details. Consider keeping a note listing the software version and settings used. Stock items you can download again may not need a copy. Never delete original footage without a second copy somewhere else.

9. Revisit and tidy on a schedule

   Once or twice a year, go through old project folders. Confirm the masters still play. Move finished projects to long-term storage and delete duplicates and test exports you no longer need.

   Storage technology changes, and files can become corrupted without anyone noticing. Opening a few old files now and then is a cheap check. If something fails, you still have your second copy.

Examples

Common mistakes

• Archiving without the project file. A master is a finished picture, not an editable one. If you want to change a title or swap a clip later, you need the project file and the media it points to. Store them together and note any fonts or plugins the project depends on.
• Keeping only the platform copy. A file downloaded from a video site has already been compressed. Using it as a source adds more loss. Keep your own export.
• Naming everything final. When several files carry the same word, no one knows which is current. Use version numbers and dates.
• Storing the only copy on one drive. Any drive can fail. Keep at least two copies in separate places and test them.
• Making the master too small. A master at a low bitrate defeats its purpose. Make it clearly better than anything you deliver.
• Deleting original footage too early. Raw footage is the hardest thing to replace. Delete it only after your decisions are final and backed up.

Best practices

• Export a separate clean version without burned-in captions or logos if you may need to translate or re-brand the video later.
• Make the master export part of your finish routine, just like checking audio.
• Write a short text note beside each master with the date, settings and where deliveries went.
• Keep delivery files separate from masters so you do not upload the wrong one.
• Check free space before a big export so it does not fail partway through.
• Use a consistent file naming pattern across every project.
