How to Choose the Best AI Video Upscaler

As more video enhancers become available, how can you choose the one that best suits your needs? Before making a decision, several factors must be considered, including video enhancement quality, supported features, processing speed, pricing, etc. By comparing these factors and referring to the detailed information in the table below, you can more easily find the best video enhancer.

UniFab - The Best Video Upscaler I Recommend

UniFab is the best video upscaling software by evaluating the information. We compared its performance with others and made this conclusion. Here are the results.

Video Enhancement

UniFab>Winxvideo

Because Winxvideo is outstanding in the field of video enhancement, we compared the performance between UniFab and Winxvideo

Based on the picture, UniFab delivers superior image clarity and detail enhancement comapred to Windxvideo, UniFab shows a clearer, crisper texture with more define edges.

SDR to HDR

UniFab>Topaz

Topaz is testing the new AI model for converting SDR videos to HDR, we tested the model and compared with UniFab.

In comparison, UniFab's overall enhancement result is better with a more detailed and realistic outcome, while Topaz focuses more on contrast and brightness, which can lead to some loss of fine details.

Denoising

UniFab>Topaz>Winxvideo

Comparison shows that UniFab has the best noise reduction effect, while Winxvideo performs the worst. UniFab completely eliminates video noise and restores details, resulting in a smooth and clean video. Topaz delivers a decent noise reduction effect, successfully removing noise but with excessive sharpening. Winxvideo's output is unusable, as the noise remains unremoved.
