🐞Troubleshooting

This page contains troubleshooting steps when you run into an error in Gyroflow.

Failed to start on Windows

If you see the following message or similar mentioning VCRUNTIME140.dll, install VC redist

Failed to export HEVC

If you see an error message like this:

...then:

• If you're on Windows or Linux, make sure you're using the latest drivers for your GPU.

• If you're using an older GPU, it may not support hardware HEVC encoding, in which case, you should try H.264 instead.

• If H.264 also fails, try disable GPU encoding completely.

Application failed to start

If you see an error message like this on Windows:

Please try downloading Gyroflow again. Everything you need is in the ZIP file that you download - you don't need to install any other dependancies manually.

No space left on device

If you see an error message like this:

It means your hard drive doesn't have enough space for ffmpeg to render to. Please make some room and try again.

Doesn't support this pixel format

If you see an popup like this:

It means your physical GPU hardware doesn't support the pixel format you're attempting to render to (i.e. normally it means your GPU hardware doesn't support 4:2:2 10-bit).

You can click Render using CPU, to render using the CPU instead of the GPU to maintain full quality, or you can pick another pixel format.

Unknown Error Occurred

If you see an error message like this:

...then:

• If you're on Windows or Linux, make sure you're using the latest drivers for your GPU.

• If you're using an older GPU, it may not support hardware HEVC encoding, in which case, you should try H.264 instead.

• If H.264 also fails, try disable GPU encoding completely.

Read Only File System

If you see an error message like this:

...and you're on Mac, make sure you install Gyroflow in your Applications folder and do NOT run it from the downloaded DMG package. Due to macOS sandboxing, Gyroflow isn't allowed to write to inside the package.

Invalid data found when processing input

If you see an error message like this:

...and you're working with RED R3D files, try deleting the MOV file that Gyroflow created next to the R3D file, and try again.
