![]() ![]() Enables hardware acceleration, and uses the hevc_qsv encoder (H.The above command performs the following: ffmpeg -hide_banner -nostdin -y -strict 2 -hwaccel auto -i "input.mp4" -c :v hevc_qsv -profile main -preset medium -max_frame_size 65534 -global_quality 19 -pix_fmt yuv420p -movflags frag_keyframe+empty_moov -vf "tvai_up=model=amq-13:scale=2:device=0" "output-artemis.mp4" Similar speed increases to those in Gigapixel would be awesome. I’m considering whether a new Zen 4 PC might be worthwhile and VEAI performance is an important deciding factor. Add `-pix_fmt yuv420p -movflags frag_keyframe+empty_moov`Įxample Command. Gigapixel AI does and Zen 4 CPUs are showing very impressive speed boosts using it.Set `-global_quality` to the desired quality.Add `-profile main -preset medium -max_frame_size 65534`.Add the `-strict 2 -hwaccel auto` flags.You can set the device by adding `device=#` to the filter argument, where # is the device index: -vf "tvai_up=model=aaa-10:scale=2:device=0" On some newer Intel devices, it may be necessary to set the `Computer\HKEY_CURRENT_USER\Software\Topaz Labs LLC\Topaz Video AI\OVUseDeviceIndex` registry entry. The following options can be used to take advantage of hardware acceleration features from different GPU manufacturers: Similarly, different encoders support different options, so you may need to tweak settings on different machines. However, different graphics cards may support different encoders and options. TVAI is used as an FFmpeg filter, and all models will work on graphics devices from Intel, AMD, Nvidia, and Apple using a command like this example: -vf "tvai_up=model=aaa-10:scale=2" In most cases, this value should not be changed from its default setting.This variable should be set to the folder containing the model definition files (.json), your authentication file ( auth.tpz), and the tvai.tz file./Applications/Topaz Video AI.app/Contents/Resources/models (macOS).Chosen during initial installation (Windows).A location with ~80 GB of free space will work best. ![]() This variable should be set to the folder where you want model files to be downloaded.Stabilization tvai_cpe + tvai_stb Video AI Command Line Usage ![]() If you log out and need to log back in without launching the GUI. Please see the Environment Variables section below.Ĭd /Applications/Topaz\ Video\ AI.app/Contents/MacOS You must manually set the TVAI_MODEL_DATA_DIR and TVAI_MODEL_DIR environment variables if launching without the GUI. The next time you want to launch the CLI without the GUI, follow the steps below: This eliminates the need to use a command to log into the app and will allow you to launch the terminal directly from the GUI.Īfter logging in, select Process > Open Command Prompt, this will set the model directory automatically. Getting Started with CLIīefore using the CLI for the first time, we recommend launching the GUI and logging into the app. This article will outline the basic functions for TVAI’s CLI, however, you will want to familiarize yourself with FFmpeg commands for more complex use cases. There is no need to install FFmpeg, it is automatically included with the TVAI installer. ![]() The majority of the commands for this build will be FFmpeg commands. We highly recommend using the app’s user interface for those not comfortable working in a command terminal. This is designed for advanced users comfortable working in such an environment and offers more flexibility in customizing a variety of scripted processes. If there’s a specific image you’d like us to see, you can send it us at this dropbox link.Topaz Video AI supports executing scripts using a command line interface. We’ll be updating TPAI regularly to address those pieces of feedback and issue reports. Please give us any feedback or report issues with this release. You can find this tool Select Subject → Brush Type options as shown here: Any feedback regarding the tool will be taken into consideration for future updates. Currently there is no on-hover mask preview for the tool, however this feature is planned for a future release. This brush is intended to be a point-and-click masking tool that provides quick and accurate results. This week we’re introducing a new masking tool - “Object Selection Brush”. ![]()
