Understanding Topaz Video AI 3.1 Preferences

Topaz Video AI allows you to customize a variety of settings that can improve performance and the overall user experience. This article will explain each of the settings found in the Preferences window.


AI Processor - Determines which computer hardware Topaz Video AI should use to process preview and export tasks. The options displayed in the dropdown may differ based on your computer hardware. If you are experiencing performance issues, we recommend choosing the CPU or discrete GPU (if your computer is equipped with one) options from the dropdown list.

Max Memory Usage - Specify the amount of system memory to allocate to Topaz Video AI. The more memory allocated, the better the performance will be. Increasing max memory usage may impact the performance of other concurrently loaded applications.

Max Processes - Select the number of tasks to run in parallel. You can choose between 1 - 4 tasks to concurrently run.

Low Power Mode - Enabling this option will reduce processing speed in order to conserve power.


Model Folder - This folder contains the AI models and resource files required by Topaz Video AI.

Temp Folder - This folder contains generated preview files and other temporary files.

Export Folder - This is the folder where all exported files will be saved. The input folder (.) is the default location for exported files.


Default Encoder - Select the default video encoder to use when exporting files.

Default Container - Choose the default file format for exported video files.

Default Bitrate (Only available when using h.264 or h.265 encoders) - Select the default bitrate for exported video files. Auto allows the selected encoder to choose the optimal bitrate. Larger bitrate values will result in a larger file size of the exported video file.

Default Audio Settings - Choose how (or if) the audio track of the input file will be preserved. Auto will first attempt to copy the audio track. If copying does not work because the encoder doesn't support it, it will attempt to transcode. Transcode will convert the audio track to whatever the encoder supports.

Video Export:

  • With Preview: Temp files will be created in the export location while processing. 
  • Without Preview: No temp files will be created and no recovery in case of failure. 
  • Use Temp Directory (with preview): A temp folder will be used to store the intermediate files. 
  • Keep Extra Headers (with preview): No temp files will be created and files may have issues with some editors/players.


Default Preview Mode - Select the default view mode when initiating a preview task. Single will display the entire processed clip in the preview area. Side by Side will display the unprocessed clip in the left half of the preview area and the processed clip in the right half of the preview area. Split will display both the unprocessed and processed clips in the preview area and split them with a vertical bar that can be dragged left to display more of the processed video and dragged right to display more of the unprocessed video.

Default Preview Scale - Select the default zoom factor when initiating a preview task. Fit will zoom the clip so that it is displayed in its entirety in the preview area.

Auto-Play Preview - Select Enabled to by default while processing. Select Disabled so playback doesn't run by default.

Processing Speed Display - Select the units to display when processing a preview or export task. You can choose Frames/Sec (frames per second) or Sec/Frame (seconds per frame).

Default Preset - Select a preset that will be applied upon loading an input video file.
