If the program closes unexpectedly during conversion, the issue is usually related to source file problems, output settings, or system resource limitations.

Follow the steps below in order. In most cases, the issue is resolved before reaching the final step.

Start here

Before changing settings, check the following:

• restart the program and try converting the file again
• make sure no other resource-intensive applications are running

If the issue continues, follow the steps below.

Common reasons and solutions

Case 1: The source file is damaged or incomplete

If the file is corrupted or partially downloaded, conversion may stop and cause the program to close.

What to do

• Try playing the file from start to finish in the program preview.
• If playback stops, freezes, or skips, the file may be damaged.
• If possible, re-download or re-copy the file from the original source.

As an additional test, you can try converting the file using Movavi’s online converter.
If conversion fails there as well, the issue is most likely related to the source file.

Case 2: Output format or location causes a failure

Some output formats or locations may cause conversion to fail on certain systems.

What to do

• Change the output format to a different one.
• Set the output folder to a local drive (for example, Desktop or Videos).
• Avoid saving the output to removable or network storage.

Then try converting again.

Case 3: Hardware acceleration causes instability

In some cases, hardware acceleration may cause the program to shut down during conversion.

What to do

• Open the program settings.
• Disable all enabled hardware acceleration options.
• Restart the program.
• Try converting the file again.

If conversion succeeds with acceleration disabled, the issue is likely related to GPU encoding.

Case 4: Graphics drivers are outdated or unstable

Outdated or incompatible graphics drivers may cause crashes during conversion.

What to do

• Check whether your graphics card drivers are up to date.
• Install updates from the manufacturer’s official website.
• Restart the computer after updating and try converting again.
