If a video app shows 0X800070057, first copy the code exactly as displayed and note the app and action that triggered it. That string is not character-for-character identical to the commonly seen 0x80070057 (it contains an extra zero), so advice for the nearby code may not apply. Microsoft’s video guidance does not establish one cause or one universal fix for this exact text. In Clipchamp, the correct procedure depends on whether a project will not open, one asset will not load, or an export fails. Keep your original media safe, then follow the branch that matches the symptom.
What does the video error code 0X800070057 mean?
The supplied code is an ambiguous identifier rather than a diagnosis. 0X800070057 differs from 0x80070057 by one zero. A transcription or display mistake is possible, but you should not silently replace the code with the shorter form. Record the complete message, the application name, and the operation that was in progress.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Microsoft’s Clipchamp material organizes troubleshooting by symptom, not by this hexadecimal string. A project-loading problem, an individual media-file problem, and an export failure require different checks. The steps below therefore begin with identification and preservation of your files, then split into those three paths.
That distinction matters because the same code-shaped dialog can appear at different points in a workflow. A project that never finishes loading points you toward memory, disk space, or a particular asset. An export that stops at a repeatable timeline position calls for a narrower media test. An application that fails with several unrelated projects is a better candidate for Windows’ Repair option. Treat the code as a clue to record, not as permission to apply an unrelated fix.

Which symptom matches what you are seeing?
Choose the closest description before changing settings. The table keeps the remedies in proportion to their likely disruption and preserves access to your project assets.
| What failed | First checks | Next escalation | Disruption | Are original project files kept available? |
|---|---|---|---|---|
| Clipchamp project will not open or remains loading | Refresh or reopen Clipchamp; check available memory and internal disk space; retry | Identify the asset whose loading indicator remains stuck and test a converted copy | Low | Yes, provided you leave the source files in place |
| One video, audio, or image asset remains stuck | Test a converted copy while preserving the original | Relink the copy in a duplicate project and compare the result | Low to moderate | Yes, if the original is retained |
| Export stops or fails | Keep Clipchamp in the foreground, close unused apps or tabs, check disk space, and retry at a lower resolution or with a shorter copied section | Inspect and replace media around the point where the export repeatedly stops | Moderate | Yes |
| The Windows app itself malfunctions across projects | Use Settings app Repair | Use Reset only after protecting project assets and only if Repair is absent or ineffective | Moderate to high | Only if you safeguard and can relink the media |
| Windows 10 Photos says a file type cannot be viewed | Confirm the source is HEVC and review codec-support options | Consider the Microsoft Store HEVC extension or convert the file | Low to moderate | Yes, when the original is kept |
This comparison also gives you a stopping rule. Start with the least disruptive action that matches the symptom. Do not jump to Reset because one clip is slow to load, and do not buy a codec extension because an unrelated editor displayed a hexadecimal code.
What should I do before trying a fix?
- Capture the exact details. Copy
0X800070057exactly, including capitalization and every zero. Write down whether it appeared while launching the editor, opening a project, importing a file, or exporting. - Keep source media available. Do not move, rename, overwrite, or delete the original videos, audio, and images used by the project. Clipchamp may need you to relink those files after a reset or other app change.
- Check the basic working conditions. Look at available memory and free space on the internal disk, especially if the project contains large media or the error appears during export. Close work you do not need so a retry is not competing with unused applications or browser tabs.
- Work on a copy when testing media. If you need to convert a file or remove a short section for a test, duplicate the project or use a copied asset. A successful test with a copy helps isolate the fault without destroying the source.
- Separate the app from the project. If possible, open another project. When other projects work, concentrate on the failing project and its assets. When several projects fail in the same way, record that pattern because it supports considering an app-level repair later.
These preparations are not a claim that storage or memory caused the problem. They simply prevent a second failure during troubleshooting and preserve the files needed for relinking. If a dialog disappears quickly, take a screenshot or transcribe the full wording before retrying.
How do I fix a Clipchamp project that will not load?
Start with reversible actions. A loading failure does not by itself prove that the hexadecimal code identifies a damaged file or a codec problem.
Refresh or reopen the project
- Refresh the Clipchamp page or close and reopen the application, depending on how you use Clipchamp.
- Open the same project again and allow its assets time to load before clicking through the timeline.
- If the project opens, save or duplicate it before further testing so you have a working copy.
Microsoft notes that a supported input file may show a loading indicator while assets are being processed; the indicator should disappear after the assets have loaded. If it remains on one item, continue with the asset-specific checks instead of repeatedly restarting the entire project. The wording from Microsoft Support is: “If your input file is a supported file type, this symbol disappears after a short amount of time once your assets have loaded.” In other words, a brief indicator is not automatically an error; a persistent indicator on one item is the useful observation.
Check memory and internal disk space
Close unused applications and browser tabs, then check that Windows has free internal storage. Retry the project after those resources are available. The purpose of this check is to remove a resource constraint; it does not establish that low memory or storage is the only possible cause. Make a note of whether the same project opens after freeing space, because that result helps distinguish a transient condition from a repeatable asset problem.
Recommended Free Tools
Test the media that remains stuck
- Identify the video, audio, or image whose loading indicator does not clear.
- Leave the original file untouched and create a converted copy in a format your workflow already accepts.
- Import or relink the converted copy in a duplicate project, then see whether the project loads normally.
- If more than one item is affected, test copies one at a time so you know which change altered the result.
If the copy works, you have isolated a file-specific compatibility or processing issue, but conversion is not a universal solution for an unrelated app failure. Keep the original so you can return to it or relink it later. A successful test also does not prove that every clip of the same extension is defective; it identifies the particular asset and workflow combination that needs attention.

Use the result to choose the next step
If reopening and resource checks solve the problem, keep the duplicate or backup you made until the project has been opened and saved successfully more than once. If only the converted copy works, continue editing with that copy only after confirming that the timeline, audio, and images remain intact. If no project opens, stop changing individual files and move to the app-level checks later in this guide.
How do I fix a Clipchamp export that fails?
Export errors need a different sequence from project-loading errors. The aim is to determine whether the failure is related to available resources, output settings, or media near the point where rendering stops.
Prepare a clean export attempt
- Keep Clipchamp in the foreground while exporting.
- Close applications and browser tabs you are not using.
- Check available disk space on the internal drive where the export is being written.
- Retry the export once those conditions are in place.
Keeping the editor in the foreground and closing unused work reduces competing activity while the file is rendered. Check the destination drive, not just the drive that contains your source clips, because the output needs space where Clipchamp writes it. Do not delete project media to create room; preserve the originals and clear only material you know is unnecessary.

If the full project still fails, export at a lower resolution or make a shorter copy of the project. A short test can show whether the export pipeline works at all without committing to another full render. Do not overwrite the original project while making this test. Keep the test copy clearly labeled so a lower-resolution result is not mistaken for the final deliverable.
Isolate a repeatable failure point
When export stops near the same point more than once, inspect the video, audio, and image assets in that section. Replace or test those assets in a copied section, then export the copy. If the shortened or altered section succeeds, continue narrowing the surrounding media rather than repeatedly exporting the untouched full timeline.
Change one thing at a time where practical: first the length, then the output resolution, then an asset near the boundary. Record which version succeeded. This does not identify a universal cause for 0X800070057; it gives you a reproducible boundary and a safer way to rebuild the affected portion.
A successful short export does not prove that the original code was caused by one particular file. It only gives you a reproducible boundary for further testing. Conversely, a failed short export with the same assets suggests that the issue is not simply the total duration, so return to resource checks or the application-level path.

How do I use Windows Repair or Reset for the video app?
Repair and Reset are Windows app options, and their availability depends on the application. Use them only after protecting project media because a reset can require files to be relinked.
- Open Settings.
- Go to Apps > Installed apps.
- Find the video application, select its menu, and open Advanced options if that entry is present.
- Select Repair and then test the app with a project.
- If Repair is unavailable or does not resolve the malfunction, return to the same page and consider Reset.
Repair is the less disruptive choice because it is the first Windows option Microsoft recommends in this situation. Before selecting Reset, confirm that your original videos, audio, and images are available outside the app. After a reset, Clipchamp may ask you to relink those files; follow the prompts using the preserved originals.
Reset is an escalation, not a routine response to a single stuck clip. It is more appropriate when the application itself fails across projects or continues malfunctioning after Repair. If the Advanced options entry or Repair button is not present, that is a limitation of the app’s Windows package, not evidence that the hexadecimal code has a special meaning.
If only one project or one asset fails while other projects work, stay with the project and media checks first. If the application fails across projects, the Windows Repair/Reset path becomes more relevant. After either option, open a test project before attempting a long export, then verify that the original project still has access to its media.

Only consider the HEVC Video Extension when all of the following are true: you are using the Windows 10 Photos app, the dialog specifically says that a file type cannot be viewed, and you have confirmed that the source file uses HEVC. In that narrow case, installing the Microsoft Store extension or converting the file can address missing HEVC playback support.
HEVC support is not a general remedy for 0X800070057 or 0x80070057. Do not purchase an extension based on the hexadecimal code alone, and do not treat an HEVC message in Photos as proof that Clipchamp’s project or export failure has the same cause. If the Photos message does not identify an unsupported file type, return to the symptom-specific Clipchamp or Windows steps instead of installing a codec speculatively.
What should I avoid while troubleshooting?
- Do not rewrite the code from memory. The extra zero changes the string you are trying to identify.
- Do not delete the original media. Converted copies are tests; they are not replacements for files you may need to relink.
- Do not reset before safeguarding assets. A reset can remove app data and leave a project waiting for its source files.
- Do not assume one successful conversion explains every failure. It may identify one problematic asset, while an app-wide failure needs Windows Repair or another branch.
- Do not install the HEVC extension solely because a hexadecimal code appeared. Its use is limited to the specific Windows 10 Photos unsupported-file message.
- Do not keep repeating an unchanged full export. Once the failure repeats near one timeline position, use a shorter copied section and test the surrounding assets.
- Do not overwrite the only working project. Save a duplicate before changing media, output settings, or app data.
- Do not treat a vendor utility as a validated fix. A program may advertise help for this error, but that claim does not establish that it repairs a Clipchamp loading or export problem.
What information should I collect if the problem continues?
After following the symptom-specific branch, keep a concise record of what happened. Include the exact code string, the app name and version shown on your device, the operation that failed, whether other projects open, the name of any asset that remains stuck, and whether a short or lower-resolution export behaves differently. Note whether the failure repeats near the same timeline position. This record prevents you from applying the project-loading procedure to an export problem and makes the next support conversation more precise.

Leave the original project and media unchanged while you collect those details. If Repair or Reset was attempted, record which option was used and whether the app then asked for relinking. Include the amount of free internal disk space you observed and whether closing other applications changed the result. Those observations are more useful than repeating the code without context.
Outbyte PC Repair markets features such as checking common Windows issues, adjusting system settings, clearing temporary and cache files, and providing an app-crash log. That is a vendor claim, not a Microsoft-validated fix for 0X800070057 or for Clipchamp’s editor-specific symptoms. If you evaluate any utility, keep your project files backed up, do not let it replace the manual symptom checks, and remember that results vary. It runs on Windows 11, 10, 8, and 7, with a free trial by category for at least two days before a paid subscription.
Frequently asked questions
Is 0X800070057 the same as 0x80070057?
No. The strings differ by one zero. Copy the code from the dialog and use the complete wording when seeking support. Do not assume instructions for the shorter code apply.
Should I delete the original file after a converted copy works?
No. Keep the original video, audio, or image in its existing location. A converted copy is only a diagnostic or replacement candidate, and Clipchamp may still need the original for relinking or for a later comparison.
What if only one project fails but other Clipchamp projects open?
Treat that pattern as a project or asset investigation first: reopen the project, check its loading indicator, and test the media that remains stuck in a duplicate copy. An app-wide Repair or Reset is more disruptive and is better reserved for failures that affect the application broadly.

Should I buy a storage drive for this code?
No specific hardware purchase is established as a fix. Check free internal disk space and preserve your media, but a general-purpose drive does not diagnose or repair the code.
