Winxvideo AI Review 2025: Real Performance, Pros, Cons & Best Alternative

Winxvideo AI offers AI-powered enhancement features—including upscaling, stabilization, and frame interpolation—designed to deliver clearer, smoother videos. But does it live up to the hype? In this review, we'll examine its real-world performance, highlight its strengths and weaknesses, and suggest a superior alternative if you need more advanced results.

Overview of Winxvideo AI

Key Features of Winxvideo AI

Winxvideo AI offers a suite of tools for video enhancement, allowing users to enhance, smooth, stabilize, convert, and edit videos efficiently. While Winxvideo AI claims to be AI-powered, its AI-related functions to enhance video are the following three:

• Super Resolution AI: Upscale low-quality videos to 720P, 1080P, and 4K with detail
• Video Stabilization AI: Stabilize shaky 4K/HD videos taken by GoPro, DJI, DSLR, mobile.
• Frame Interpolation AI: Convert video from low 24/30fps to higher 60/120/240/480fps.
• Audio AI: Reduce background noise from audio and video files.

In addition to enhancing videos, Winxvideo AI also features AI Image Enhancement, Convert Videos, Record Video, etc. to meet the different needs of users.

How Does Winxvideo AI Perform?

Through detailed tests on Winxvideo AI's performance, we found that the processing results did not meet our expectations, and the Super Resolution AI and Frame Interpolation AI were not as useful as other AI enhancers. In particular, the Video Stabilization AI hardly worked. Let's take a look at how it performs below.

Super Resolution AI

Winxvideo AI's Super Resolution AI features four AI models: Gen Detail v2, Real Smooth v2, Anime, and Zyxt. It also offers two output modes: High Quality Mode and Fast Mode. 

To assess real-world performance, we tested all models on a 10-second, 720P video at 24 FPS, upscaled to 4K resolution. The Video enhancement quality results: Gen Detail v2 > Real Smooth v2 > Zyxt

Let's dive into the performance of each model when enhancing video from 720P to 4K resolution.

Gen Detail v2
Original (720P)
High Quality Mode (4K)
Fast Mode (4K)

Processing speed

• Speed ranges from 2.65 fps to 4.50 fps.
• Export time ranges from 1 minute 10 seconds to 2 minutes.

Processing effect

• The difference in performance between Fast Mode and High-Quality Mode is minimal.

Real Smooth v2
Original (720P)
High Quality Mode (4K)
Fast Mode (4K)

Processing speed

• Speed ranges from 3.45 fps to 3.52 fps.
• Export time ranges from 1 minute 20 seconds to 1 minute 40 seconds.

Processing effect

• The Fast Mode results in a generally darker image, with a more rigid recovery of shadows and mountain textures.
• The High-Quality Mode provides a smoother and more refined effect.

Anime
Original (720P)
High Quality Mode (4K)
Fast Mode (4K)

Processing speed

• Speed ranges from 2.64 fps to 2.70 fps.
• Export time ranges from 1 minute 30 seconds to 2 minutes.

Processing effect

• The difference between the High Quality Mode and Fast Mode is minimal, with the Fast Mode even performing slower than the High Quality Mode in some tests.

Zyxt
Original (720P)
High Quality Mode (4K)
Fast Mode (4K)

Processing speed

• Speed ranges from 2.53 fps to 2.70 fps.
• Export time ranges from 1 minute 40 seconds to 2 minutes.

Processing effect

• Advantages: There is a noticeable increase in portrait detail and improved clarity compared to before.
• Disadvantages: The overall texture of the image is not very high, resulting in a slight smudged appearance.

Frame Interpolation AI

We tested Winxvideo AI’s Frame Interpolation feature using a Kobe Bryant basketball clip to evaluate its real-world effectiveness. While the AI shows promise in increasing frame rates, there are clear limitations to be aware of:

• When increasing frame rates to 90fps and above, many scenes exhibit visible motion artifacts and obvious AI-generated frames, which can distract from viewing.

• The “skip scene change” feature helps reduce these artifacts by avoiding interpolation during abrupt cuts, resulting in noticeably smoother playback. However, even with this feature enabled, the smoothness still falls short of native high-frame-rate footage such as true 150fps video.

Overall, Winxvideo AI’s Frame Interpolation improves motion clarity but doesn’t fully replicate the quality of original high-frame-rate recordings.

FPS	Performance
Original Video (30FPS)
×2  (60FPS)
×3  (90FPS)

Video Stabilization AI

Winxvideo AI offers video stabilization with two main modes—One Pass and Two Pass (the latter being recommended for better results)—along with four preset options: Best Stability, Fastest, Balanced, and Minimum Crop.

However, unlike image enhancements, the impact of stabilization can be hard to capture in screenshots, so we evaluated the feature through real video comparisons.

How Effective Is the Stabilization?

• Two Pass Mode: The improvement is subtle. While some shake is reduced, the change isn’t very noticeable to the average viewer. The main visible difference is that the video is slightly cropped, which is common practice to compensate for movement during stabilization.
• Preset Modes: Each preset offers a balance between stability and cropping, but overall, the stabilization effect is moderate. It does help smooth out minor jitters but falls short in handling more significant shakiness, especially from handheld or action camera footage.

Processing Speed

The stabilization process is quite fast. All modes analyzed a 4-minute video in approximately 2 minutes, which means it’s efficient even for longer clips.

Summary

While Winxvideo AI's stabilization feature performs efficiently and can smooth minor shakes, users should not expect dramatic stabilization effects—especially for more intense or fast movements. For typical everyday footage, it provides a modest improvement but may struggle with heavy shakes common in smartphone or action camera videos.
