The procedure entry point clReleaseDevice could not be located in the dynamic link library OpeCL.dll. im using hitfilm first time so i dont know what that means
You should list your system specs - CPU, GPU, OS, RAM and Storage.
This error indicates one of two things - either your hardware is under spec to run Hitfilm or your GPU drivers are out of date. OpenCL.dll is a GPU driver component.
now i understand it probably will be my 8 years old graphic card but thanks for reply
