How to check a video-editing PC before a deadline

Your editing PC may seem fine until playback stutters, an export slows down, or the drive fills up at the worst time. Before a deadline, check the hardware and storage, then test a small section of the actual project you need to deliver.

Test Everything checks your computer's hardware step by step and gives you a report. Its results can help you spot a device problem, but a short test in your video editor is still the best way to confirm that your project plays and exports correctly.

Check your PC before the deadline

1. Open Test Everything on the PC you use for editing. Follow the tests and note any failures or warnings in the report. If time is tight, do this well before your final editing session so you have time to troubleshoot.
2. Check the processor, graphics, and storage with the Processor Test, Graphics Test, and Storage Test. These give you a browser-based performance check on this computer, not a guarantee of how quickly a specific editor will render.
3. Look for signs that heat affects performance with the Overheating Test. It puts the processor under full load for a few minutes, so run it while plugged in and only when you can let the computer cool afterward.
4. Open the project you plan to deliver. Play a representative section that includes the kinds of footage, effects, titles, and audio you use. Check for pauses, missing media, unexpected color, and audio that goes out of sync.
5. Make a short test export using the intended resolution, frame rate, and file format. Save it to the drive you plan to deliver from, then play the exported file from start to finish. Confirm that the picture, sound, and duration are right.

Before the real export, check that the project, source media, cache, and output location are all available. A project can open while still depending on footage or audio files stored on a disconnected drive.

What the results mean

The hardware checks look normal and the sample export works

Your PC and this project are behaving as expected in the checks you ran. That does not rule out a problem that appears only during a long export, so keep a copy of the project and make sure you have enough time to export and inspect the final file.

The browser tests look fine, but editing stutters

A browser benchmark is not the same workload as a video editor. Your editor may use different codecs, effects, graphics acceleration, and media storage. Trust the project playback and sample export for this job, and check the editor's own performance and playback settings.

A test is much slower than you expected

A low score alone does not prove that a part is failing. Browser, power, temperature, and background activity can affect results. Close other demanding programs, keep the computer plugged in, and repeat the same test once. If it remains slow and the editor also struggles, investigate the relevant component.

The project pauses, goes offline, or exports incorrectly

This points to a workflow problem as well as a possible PC issue. Check that all media is online, that the output drive has space, and that the short export uses the correct settings. A successful hardware report cannot confirm that a project file, media link, or export preset is correct.

How to reduce deadline risks

1. Check available storage. On Windows 11, open Settings › System › Storage. On macOS, open System Settings › General › Storage. Make room on the drives used for source media, editor cache, and exports, but do not delete project files or cache folders without knowing what they contain.
2. Close other demanding programs. Quit games, large downloads, extra editing projects, and apps using the GPU. Then test playback again. Avoid running several benchmark tests while the editor is exporting.
3. Use a reliable power source. Connect a laptop to its charger. On Windows 11, check Settings › System › Power & battery. On macOS, check System Settings › Battery. Power modes and battery limits can reduce performance, especially during longer work.
4. Check media and output locations. Reconnect external drives and confirm the editor can read the project files. Export a short sample to the intended destination, particularly if it is an external drive or network location.
5. Leave disruptive changes until you have time. If the editor, graphics driver, or operating system needs an update, do it before the deadline, restart, and test the project again. Avoid changing several settings at once right before delivery.
6. Back up the project and source files. Save a separate copy of the project and confirm the media it needs is available. If a drive makes unusual noises, disconnects, or reports errors, stop writing to it and copy important files to a known-good drive before further testing.

When it may be a hardware problem

Suspect a hardware fault if the same part repeatedly fails a check, the computer freezes or shuts down under load, a drive disconnects on more than one port, or the problem follows the PC across different projects. A browser test cannot identify every fault, and a normal score does not certify that a component is healthy.

Back up important work before testing a drive that may be failing. For repeated overheating, sudden shutdowns, or storage errors, stop the heavy workload and seek repair advice. If the computer is under warranty, contact the seller or manufacturer before opening it.

Why the project test matters

Video editing depends on the source format and the work in the timeline. High-resolution footage, effects, color correction, and multiple video layers can behave very differently from a short browser test. A short export made from your real project checks the whole path: media, editor settings, processing, storage, and playback of the finished file.

Keep the test export and the original project separate from your final delivery, so you can confirm the final file without overwriting your working copy.
