Vivid Glam Video/Photo Retouch is an iOS-exclusive AI video upscaler app. This AI tool upgrades blurry clips into eye-catching content with a single click. Leveraging AI magic, it can speed up the enhancement process and create high-resolution results in seconds. Achieve a flawless, personalized look with its powerful facial reshaping and skin-smoothing features.
To begin, we started by evaluating the performance of one of the best video upscaler apps, Vivid Glam. The upload speed was quick enough, taking no more than 2 to 3 seconds. Similarly, processing a 17-second video clip took only a short time, i.e., 10 to 12 seconds.
Talking about the performance and effectiveness of the app, we really loved the high-quality (upscaled )results. While the tailoring options really helped us customize the output, the noticeable video enhancement was the show stealer of all.
Our experience with Vivid Glam Video/Photo Retouch was worth it. Navigation felt seamless thanks to its minimalistic and well-organized screen. All options were neatly organized and accessible without any prior experience. After uploading the video, we were offered two options: Beautify and Edit. We went ahead with Edit to Enhance and denoise our clip. While the free version provided most options, such as trim, crop, and adjustments, we had to upgrade to the premium (pro) version to unlock the ‘Video Enhancement' option.
Once upgraded, we can work smoothly with several features, including stabilization, AI color correction, and video denoise. The video processing didn’t take much time and provided noticeable improvement in the final outcome. However, its limited free usage may not please users on a low budget.
Pros
Didn’t require any sign-up or account creation.
No intrusive ads or pop-ups.
Provides options to beautify and edit the media clip.
Works well with local media storage and direct camera recordings/images.
Cons
The free version does not have the video enhancement function.
Requires a high premium subscription to unlock all video enhancement features like stabilization, AI color, and denoise.
Available only for iOS users (iPhone, Mac, and Apple Vision).
Limited editing and customization options, despite upgrading to the premium version.

Next, we have Video Quality Enhancer, exclusively for Android users. This video upscaler app offers a general model to enhance old video clips. Additionally, it can denoise and enhance video clarity for improved visuals. It can increase the video resolution up to 4K and even colorize black and white videos. The app also excels in restoring old video quality with the freedom to adjust specific video parameters.
Video Quality Enhancer took no more than 1 to 2 seconds to upload the original video. However, the processing time shook our patience. Processing just a ‘Medium’ quality video took over 50 seconds. And a ‘High’ quality processing took approximately a minute. But the results didn’t please us much. Though the difference was visible, it was clearly not in terms of enhancement. To say, the colors, brightness, and even contrast were not up to standard.
So, we experimented with the ‘Very High’ feature. Sadly, it ran 2 ads for over 1 minute to 1.5 minutes where we were offered to install those apps (in the ads). We skipped and moved ahead. And that’s when we settled for the final quality, which was again not very appealing. The video frames appeared almost identical, just with an elevated contrast.
Our experience with Video Quality Enhancer was nothing short of a disappointment. While its interface was generally good, with just two options — Enhancer and Creation — there wasn't much to explore. The app lacks AI models to detect individual frames and process them. It does not even give manual controls for output customization. We have already discussed the app’s performance in detail above. While users on a low budget can try it, there’s not much they can expect; contrary to its name, it doesn't even offer ‘enhancement.’
Pros
No watermark on the final outcome.
Very simple, neat, and organized interface.
No intrusive ads or pop-ups on the app’s interface (excluding using one feature: ‘Very High’).
No sign-up or account creation is required.
Cons
No manual control over the final outcome.
No customization option for preferred resolution, codec, frame rate, and so on.
No feature beyond enhancement, such as edit, etc.
No visible video enhancement; just adjust the video contrast.
A long processing time just to enhance a short video clip.

Coming up next, we have Videoshop - Video Editor. It is undoubtedly the best free video upscaler app. The amazing app offers a range of editing options, including trimming, adding music/sound effects, and slow-motion or fast-motion effects. It can also adjust display, merge multiple clips, and give voice-overs to videos. That’s not it. Its unique filters and transitions help enhance video clips and produce high-resolution video of up to 4K resolution. You can resize, reverse, copy, and even share the enhanced/edited clips on social media channels or send them through emails.
The video’s import speed was good enough, taking no more than a second. However, the processing time depends on your manual controls. The higher the editing level, the longer it takes to deliver the final output.
Videoshop does not have a dedicated ‘Upscaler’ feature. However, it lets you adjust the brightness, contrast, temperature, sharpness, blur, saturation, vibrance, and more filters for a decent output. The free version can increase the video’s resolution up to 1080p, and you can further adjust these parameters for improved results.
Videoshop - Video Editor was indeed a fun app to work with. It has a simple and neat interface with no ads or pop-ups. We were not even asked to create an account. And most of the features were available in the free version itself. We just selected the filters and adjusted the settings to control the levels of brightness, contrast, saturation, sharpness, and more details.
Overall, we had complete control over our output. There were no AI models available to upscale the video clip with a single click. However, the results were visibly improved, and we were pretty pleased with the high controls that allowed us to achieve customized results. The free version even allowed us to export the video in up to 1080p resolution and at 30 or 60 frames per second (fps). No wonder it has high user ratings on the Play/App Store. However, for those who need quick results and lack a knack for editing, they may struggle to achieve good results.
Pros
No intrusive ads and popups.
Plenty of editing features for customization.
No watermark on the final outcome.
Very simple, neat, and organized interface.
Does not require signing up for the app.
Most of the features are available to use in the free version.
Offers the option to upload the full-length video clip or trim according to the specific social media platform.
Cons
Offers only a 7-day free trial.
Requires the pro version to get 4K quality results, as the free version offers only up to 1080p quality.
The watermark is removed from the final video only once if you follow them on social media platforms like Facebook, Instagram, or TikTok.
No direct upscaling or enhancement feature.
No AI-trained models to increase the resolution or upscale videos.
Requires a decent amount of editing knowledge and patience to get good results.

KineMaster, a free AI video upscaler app, can be the best pick for users on a tight budget. Promoted exclusively as a video editor, it can edit everything from vlogs, reels, shorts, to full-length movies. Harnessing the power of AI, KineMaster can magically enhance the size of low-resolution media and even add artistic effects to video clips. It offers professional video editing by making advanced tools easy to use, even for new users. KineMaser can be the best pick to upscale the videos and jumpstart your creativity today!
Next, we used KineMaster to assess its performance, specifically its speed and effectiveness. The upload speed was quick, taking no more than 4-5 seconds. However, the processing took approximately 20 seconds to enhance and upscale (X4) the media file.
Once upscaled, KineMaster offered us three options for saving and sharing the video. We could choose QHD 1440p at a frame rate of 50, FHD 1080p at 30 fps, or HD 720p at 25 (PAL). By default, FHD 1080p at 30 frames per second (fps) was selected. However, the results didn’t seem accurate to the chosen resolution and failed to demonstrate a noticeable improvement in quality.
Our experience working with KineMaster on our Android phone didn’t seem fruitful. The results failed to parallel its global popularity and did not truly meet our expectations. We clicked the ‘Create’ button and imported the same video clip as tested earlier to upscale and enhance. Despite displaying the selected option as ‘FHD 1080p’ on screen, the free video upscaler app didn’t show visible quality improvements for future use.
KineMaster allowed us to select video codecs, such as H.264 for compatibility and H.265 for high efficiency. We were also given a slider to adjust the bitrate and file size according to the device’s storage capacity. While the user interface appeared a bit confusing at first, we figured out how it worked in a couple of minutes. The app offers several customization options to enhance results and achieve tailored outcomes.
Pros
Offers several aspect ratios for customization.
Provides advanced features for personalized outcomes.
Supports control over the stored media on your device: limited access, all, or none.
Dedicated Super Resolution technology to apply AI for improving the media file.
Does not require sign-up or account creation.
No ads and pop-ups to deliver a smooth operation.
Cons
Only a 3-day free trial.
The downloaded video has a watermark in the free version.
Limited color grading with no true color tone.
No visible signs of quality improvement in the final outcome.
Drains significant RAM, slowing down the device while working with lengthy videos.

Lastly, we have HiQuality, an AI video upscaler app. This professional-grade video quality enhancer makes your videos clearer in just one click. Taking the resolution high (up to 4K), it adds life to dull, old, and low-quality video clips. Regardless of the type of video you have, HiQuality works smoothly on 2D/3D cartoons, anime, selfies, and black and white movies. It lets you beautify and enhance videos downloaded from social media channels like TikTok and YouTube as well. Using the most advanced algorithms, HiQuality can be your best bet to make your videos clearer.
The video’s upload speed was pretty good, taking approximately 2 to 3 seconds. However, the free version does not show noticeable improvement in resolution. While the quality remains the same, it simply removes the noise, adding slight sharpness to enhance the outcome.

HiQuality offers several options on the main interface, and they are well-organized to fit the screen. We could easily jump right into editing without a learning curve. The performance doesn't stand out much as the free version lacks excessive manual controls or customization options. Even the processing speed is good, but only for short video clips. Lengthy videos can take a considerable amount of time to process, which can result in error messages. Sometimes, you may even lose your pro card when the processing fails. So, we don’t vouch much for HiQuality.
Pros
The final outcome does not have a watermark logo.
4 unique AI-based models to enhance and optimize the video frames.
User-friendly interface, making it a breeze to get pro-grade results without prior technical knowledge.
GPU-accelerated speed to fasten the upscaling process while maintaining balanced video quality.
Works flawlessly with different kinds of video clips, such as anime, blurred, or jittery low-quality videos.
Restores the crisp lines and vibrant colors in the original video footage.
Cons
Currently available for Windows and Mac only, not for mobile devices.

Professional AI-powered Video Upscaler
Uploading our video clip was quick, finishing in under a second. However, we were doubtful about the processing speed. But, to our surprise, it delivered more than we anticipated. It seamlessly blended AI models with manual controls. The AI models improved the video’s texture and let us customize output settings to fit our needs. Undoubtedly, the results were smooth and flawless. They impressed us far more than we thought they would.
UniFab’s upscaling and enhancement were truly beyond our expectations. Like, we did expect it to perform better than the free video upscaler apps. However, we didn’t expect it to perform this well. Its accelerated speed and visible 16K quality blew our minds. It was as if the results spoke for themselves. The realistic beauty and soft naturalness of the frames were beyond amazing.
The best part was that, despite being a professional-grade software, we could easily navigate the functions. The free trial included all the pro-level (advanced) functions, providing a smooth, hands-on experience. It was indeed the best free video upscaler app, allowing us to thoroughly explore its capabilities before making a commitment.

Step 2: Pick an AI model— we chose the Texture Enhanced one. It improves textures and shows tiny details to make videos clearer. Customize video settings like resolution, codec, and format to fit your needs.
