1. AVCLabs Video Enhancer AI

When using AVCLabs Video Enhancer AI to process this video, my impression was that it was simple, easy, and fast. This tool falls somewhere between a complex video editing tool and a simple online tool. It helps you quickly obtain footage with significantly improved image quality.

After processing, comparing the images, you can see that the video is cleaner, and the contrast is more natural. More importantly, the edges of the feathers didn't become blurry despite being upgraded to 4K. Noise is naturally reduced, and there's no artificial AI look caused by over-sharpening. AVCLabs also allows you to batch enhance, so you can line up your long videos neatly for processing.

AVCLabs Video Enhancer AI is very easy to use, effortlessly producing videos that look like they were shot with a professional camera. Even when enhancing video footage with complex backgrounds, the overall image looks "comfortable" and "harmonious." However, if you need to process mid-to-long-range shots of fast-flapping wings, and you don't mind spending some time learning, I recommend considering more complex video editor.

Additionally, based on the product description, AVCLabs Video Enhancer AI is particularly effective for enhancing videos that contain faces. Through side-by-side comparisons, you can clearly see that facial features are naturally enhanced without losing detail to the AI model. By setting the preset to Upscale to 4K and enabling the Ultra model, you can achieve beautifully restored, highly natural-looking facial videos.

2. Topaz Video Enhancer

Topaz Video Enhancer is a highly professional AI video enhancement tool and the most complex to operate among these five tools. Therefore, it is very fitting to summarize the testing process with "patience" and "surprise." In other words, you need some basic editing skills to quickly master and use this tool. It offers a wide variety of models, including unblur and denoise.

It also integrates an online portal within the software. If you purchase its credits, you can directly use the online version. Based on our tests, the functionality of the online tool is no less impressive—it feels as if the team specifically designed it for users who are unwilling to learn professional software.

Topaz Video AI allows you to enhance video quality up to 8K 120fps, which is sufficient to meet most demands for enhanced footage. However, in scenes where a bird flies past the tree, the tool still struggles with rendering the tree's shadows smoothly. That said, if your budget allows, it remains a tool well worth trying.

Moreover, Topaz Video AI performs exceptionally well in processing severely damaged videos. The supplemented details blend naturally with the environment, without being "discarded" or "over-emphasized". However, if you set the sharpness too high, severely damaged videos may look a bit “cartoonish” after enhancement.

3. HitPaw VikPea AI

HitPaw VikPea AI is friendly for those who are not familiar with video editing. It is said that this tool performs well when processing footage of flying birds, forests, skies, and natural environments. We also tested this tool using both bird videos and videos containing human faces.

If you have blurry, noisy, or heavily compressed old videos, VikPea's AI restoration capability is quite impressive. It not only upscales the resolution but also intelligently reduces noise and restores colors. Hitpaw AI video enhancer offers multiple models, including those suitable for enhancing landscapes, animals, and outdoor scenes.

When enhancing videos with faces, you need to consider the clarity of the footage you import. This is because the tool cannot yet perfectly improve faces with fast movements or frequent changes, and it may easily lose facial details. If the preset clarity is not set high enough, the enhancement may also appear less noticeable.

4. Vmake AI Video Enhancer

Website: https://vmake.ai/video-enhancer

Vmake AI Video Enhancer was the only online tool among the five AI video enhancers tested. Upon importing our sample footage into Vmake AI Video Enhancer, we observed significantly faster loading and processing speeds. Unlike other web-based solutions, it played the video smoothly immediately after import without any stuttering.

Another distinctive feature we noted during testing is its completely automated workflow. Processing starts automatically right after upload, with a clear progress bar displayed at the bottom of the interface (as shown in the screenshot below) to indicate the enhancement status.

Once the processing is complete, the interface will display two video screens side-by-side for comparison. When you click play, the original and enhanced videos will run simultaneously. The improvement in quality is striking. You can click on either video screen (Original or Enhanced) to zoom in for a closer look. Details are noticeably refined, with minimal blurring or smearing in most scenes. However, it's worth noting that the tool does not support resolutions beyond 4K.

By default, Vmake AI video enhancer upscales your video to UHD resolution. You also have the option to select 4K specifically. If you change the setting, a progress bar will reappear, and another waiting period will be required. After processing, you can preview the first 5 seconds for free. However, downloading the full video requires a subscription to Vmake Pro at $9.99 per month.

In addition, Vmake offers specialized enhancement modes for specific content types—such as portraits, gaming footage, and anime clips. Overall, given its performance and features, this tool is best suited for shorter clips. It works especially well for enhancing videos intended for social media platforms.

5. UniFab Video Enhancer AI

UniFab Video Enhancer AI offers limited adjustment options. After importing a video, you can view the video data, including resolution, format, and size, in a small area on the right. In addition, it provides simple Crop and Trim functions, as well as audio settings adjustments. Furthermore, adding text to the video is also supported.

During testing, we imported a 4.98 MB MP4 video file. It can upscale to 1080p by default, but you can also adjust it to 4K resolution. After setting it up this way, click "Start" to launch Unifab Video Upscaler. We got pretty good results; the bird's eyes in the video were enhanced and looked very bright, as if it could see me.

However, the enhancement between the feathers and the foreground and background wasn't very good, resulting in a slightly artificial look. Secondly, the enhancement effect wasn't very noticeable in footage where the bird was flying at a slightly faster pace.
