I want to output it at 3840 x 2160, or 4K. As I mentioned at the beginning of this article, the resolution of this source clip is 1280 x 720, or 720p. This setting will determine the upscale rate of the output video. The next setting I will choose is the output size. This will tell Video Enhance AI to analyze the current frame and choose the settings it thinks would be optimal. With that model’s quadrant highlighted, I click the Auto-detect Settings button (which looks like a lightning bolt). I have several fine-tuning settings specifically with the Proteus model that I want to pay attention to. Now that I’ve selected the three AI models to compare, I need to choose what my model and output settings will be. Step 4 - Choosing model and output settings Have you ever viewed a low-resolution video at full screen? All of the details become blocky and it can almost be an impossible task to decipher what you’re looking at. And you probably know what I mean by “quite bad”. And there’s good reason for it! Depending on when a video was first digitally recorded or digitized from an analog source, the resulting clip could be very low resolution, making it look quite bad when viewing at full screen. In fact, one of the most prevalent video question themes I get asked has to do with how to make videos HD or 4K. One of the most common use cases I see for Video Enhance AI has to do with upscaling-or increasing the resolution of-videos. Step 4 - Choosing model and output settings.Step 1 - Load the video file into Video Enhance AI.Using Video Enhance AI to convert video to HD. ![]() 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" Add `-pix_fmt yuv420p -movflags frag_keyframe+empty_moov`Įxample Command.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"
