The length and the size of the source file.

Settings for output files, such as resolution and video bitrate.

Computer configuration

Here are some tips that can help to speed up the conversion:

  • Open the program and go to "Preference" windows. Then, enable NVIDIA GPU Acceleration, enable Intel App Acceleration and Enable AMD APP Acceleration.
  • Don't run other programs on the computer while converting.
