Winxvideo AI is an incredible AI-powered video enhancer and upscaler, making old videos back to life. Its AI models trained by the advanced deep learning algorithms is exceptional at scaling video up by 200-400%, enhancing video resolution to 4K, and therefore bringing old memories new again!

1 Click "Video AI" button to enter video upscaling window.

enhance video

2 Tap "Add Video" icon at the bottom of the window to load your input video file. Or just drag and drop the video you want to enhance to the main interface. You can preview your enhanced video effect via the preview compare window or full window.

3 Tick "Super Resolution" option and choose your preferred AI model. Winxvideo AI offers 4 dedicated AI models to help you enhance and upscale different types of videos.

  • Gen Detail v2: This AI model excels in adding authentic details while improving video clarity and sharpness. It excels in enhancing videos that require meticulous attention to details like skin, hair, animal fur, architectural textures, etc, while addressing blur and noise issues in bad-quality contents.
  • Real Smooth v2: This AI model specializes in rendering smoother, clearer, and brighter videos, and restoring original. This AI model is tailor-made for enhancing contents with relatively fewer details, such as 2D contents, glass surfaces, smooth textures, and line drawings.
  • Anime: The AI model is tailor-made for upscaling and denoising anime and cartoons.
  • Zyxt: It is designed for enhancing and upscaling photorealistic photos of low resolution, producing realistic and visually appealing results with improved detail and sharpness.

4 Choose a quality mode or speed mode based on your preference.

  • Fast Mode: Prioritize speed for rapid processing, ideal for speeding up computer-intensive projects and enhancing large video files quickly.
  • High Quality Mode: Focus on superior visual quality, delivering exceptional details and enhanced clarity.
denoise level

5 Do some model settings.

5.1. Choose the Scale or Resolution presets you need. You can opt for 2X, 3X or 4X. The default setting goes to 2X. For video resolution below 1080p, you’re advised to choose 3X or 4X at your disposal. As for video resolution 1080p or even higher, 2X is the best option. Or you can choose the Resolution profiles, ranging from 480p, 720p, 1080p, 2k, to 4K.

Generally, the higher the multiplier, the higher the resolution clarity, but it may appear less natural. It is recommended to try different settings and preview to achieve the best results. In most cases, a two-step 200% multiplier yields better results than a one-time 400% multiplier.

5.2. The option "Enhance Video (1X)" is used in cases where the resolution remains unchanged, or the original resolution is relatively high, and the goal is to remove noise, blur, pixlation, and enhance the image quality without upscaling.

upscale video 2x

6 Trim your video length before video upscaling and enhancing. Move the progress bar to cut off the unnecessary clips and keep your desired video duration.

7 Select output video codec, quality level and GOP. Move your mouse to the lower right-hand corner of the interface and tap Export Settings, where you choose output video codec H264 or HEVC, quality level (from Low to Highest) and GOP.

export video

Note: GOP stands for "Group of Pictures". In video coding, it's a collection of pictures in a coded video stream that specifies the order of frames. In general, the smaller the value, the higher the quality, and the larger the value, the greater the compression. For videos with minimal motion, a value between 90 and 250 is generally sufficient; for fast-paced scenes with frequent scene changes or for GOP values used in post-production processing, a value of 30-60 is common.

8 Click "Browse" button to choose a file folder for the output video storage.

9 Hit the "RUN" button to begin enhancing video quality at GPU hardware accelerated speed.

2-3. Frame Interpolation

Winxvideo AI Frame Interpolation function will automatically interpolate intermediate frames and increase the video frame rate (fps). By converting videos that are originally around 24fps or 30fps to high frame rates such as 60fps, 120fps, 240fps and beyond. Therefore, you can make choppy videos more natural, smooth, and create a stunning slow-mo video with ease.

This function is very suitable for anime and fast-moving action movie frame interpolation. Follow the steps below to boost your video frame rate with AI.

1 Navigate to AI Frame Interpolation window just by click "Video AI" on the main UI. After clicking on the "Video AI" button, wait for the Hardware Detection process to complete.

2 Click on the "Add Video" button or simply drag and drop a video you want to interpolate video frame to this program. Once loaded, you will get the operation panel.

Section C: Frame Interpolation Settings

Check "Frame Interpolation" box and you can start frame interpolating your video to 60fps, 120fps, 240fps, and even 480fps..

[GPU]: The hardware configuration of your PC will be automatically scanned, so select an available GPU.

Set FPS: Choose from 2X, 3X, 4X, and 5X to set the desired FPS.

  • [2X]: Double the frame rate. For example, you can change a video that originally had a frame rate of 30fps to 60fps.
  • [3X]: Triple the frame rate. For example, you can change a video that originally had a frame rate of 30fps to 90fps.
  • [4X]: Quadruple the frame rate. For example, you can change a video that originally had a frame rate of 30fps to 120fps.
  • [5X]: Quintuple the frame rate. For example, you can change a video that originally had a frame rate of 30fps to 150fps.
frame interpolation settings

Tip: To achieve the desired frame rate, one can repeat the process multiple times to reach the target frame rate. For instance, selecting 2X twice can convert a 30fps video to 60fps and subsequently to 120fps. This approach yields superior output quality compared to directly choosing 4X.

Skip Scene Changes: Whether to always compare the difference between two frames and not insert the frame if the difference is too large.

skip scene change

- When to disable it:

If the scene in the video does not change much, there is no need to check this option. For example, if the adjacent frames are all about playing basketball, Winxvideo AI will interpolate your video to give you a smoother and higher-quality video.

- When to enable it:

If the adjacent frames are very different, you are suggested to check this option to not perform frame interpolation to avoid artifacts. For example, the first frame is about playing basketball and the second is about playing table tennis where the two pictures change a lot, enable this option will tell Winxvideo AI’ frame interpolation function to skip the two frames.

When "Skip Scene Changes" is enabled, you can adjust the value of "Sensitivity" to detect scene changes.

[Sensitivity]: You can set the value from 0 to 100. A higher value will assume and skip more scene changes. The best sensitivity setting is 85.

If the value is low, you tell Winxvideo AI the scene changes less, and the frame interpolation will be more frequent. However, the actual scene changes a lot and should not be interpolated. As a consequence, the frame interpolation makes the video look bad.

If the value is set high, you tell Winxvideo AI that the scene changes a lot and it will skip the adjacent frames. The interpolation frequency is relatively low, which also avoids picture distortion.

Slow Motion: Slow down playback speed to see more details.

Create slow-motion video by choosing 2X, 3X, 4X, or 5X to slow down the playback speed. For example, you can create a slow-motion video about the passing through an egg, a water glass, a watermelon, etc.

make slow-mo video

Section D: Export Settings

Once you finish adjusting the frame interpolation settings, you can set the export settings.

  • Video Codec: You can choose H.264 or HEVC to encode your video.
  • Audio Codec: You can choose Passthrough or AAc to encode your audio. *Pass-through is a safe choice if you want to copy the source audio without changing it, and AAC is a safe choice if you want to reduce the file size while maintaining high audible quality.
  • Quality Level: You can choose output video quality from Low, Medium, High, and Highest.
  • GOP: The smaller the value, the higher the quality, and the higher the value, the greater the compression. For videos with little movement changes, 90-250 is generally sufficient; for videos with fast action and many scene changes, the GOP value is generally 30-60. If there is no particular need, simply use the default value of GOP as is.
  • Output Folder: Click on the "Browse" button to choose a folder on your computer to save the interpolated video. Or click on "Open" to open Winxvideo AI folder.

3 Hit the RUN button to start the frame interpolating your video with Winxvideo AI.

Note: Your export video will be saved in MP4 format. If you need another format, you can use Winxvideo AI’s "video conversion" function.

2-4.Stabilize Video

Winxvideo AI utilizes advanced AI algorithms and GPU hardware acceleration for efficient video stabilization. Offering four presets, the software simplifies the process for you. You can choose based on your preferences: optimal stabilization, faster processing speed, minimal cropping, or a balanced approach among stabilization, speed, and cropping. Selecting a preset starts the video analysis and stabilization process without the need for complex parameters. Additionally, you have the option to customize border color fill, cropping method, and crop ratio.

1 Select "Video AI" from the main interface to access the video stabilizer tool.

2 Drag and drop the video you wish to stabilize into the pop-up window. Alternatively, you can click the "Add Video" button at the bottom left corner to load target videos.

- About Preset:

  • Best Stability: Provides the best video stabilization but involves some cropping.
  • Balanced: Balances video stabilization, cropping, and speed.
  • Fastest: Offers the fastest speed but with average stabilization and some cropping.
  • Minimum Crop: Involves minimal cropping with average stabilization effect.
stabilize video preset

Note: You can also take advantages of the Border Color, Crop Type, and Crop Ratio options to further optimize the stabilized video.

- About Border Color: It defines how the video edge is filled.

  • Default: Uses black color to fill in the edge information.
  • Replicate: Fills in the edge information by replicating edge pixels.
  • Reflect: Copies and fills the edges symmetrically based on adjacent pixels.

It's recommended to choose "replicate" or "reflect" to restore lost edge information.

stabilize video color

- About Crop Type: It defines the method of cropping the frame.

  • Fixed: Suitable for videos with translational shake where the shake frequency is relatively consistent and mild.
  • Dynamic: Suitable for videos with significant shake variations, automatically analyzing the shake frequency to apply different cropping ratios and prevent displacement.
  • Customize: Offers flexible customization of cropping ratios based on user preferences. When CropType is set to "Customize", you can adjust Crop Ratio value. Crop Ratio determines the area of the frame to retain. A higher value crops more, resulting in better stabilization, while a smaller value retains more of the frame, leading to a less effective stabilization. After adjusting the crop ratio value, you can preview the effect in real time.
stabilize video crop

4 Preview the stabilized video and readjust the settings if needed.

Tip: To apply settings to all imported videos, use the "Apply to All" button.

5 Adjust export settings: specify video codec, audio codec, quality level, GOP, and output folder.

Video codecs available include H.264 and HEVC. Audio codecs include Passthrough and AAC. Quality levels range from Low to Highest.

In general, a smaller GOP value typically results in higher quality, although it also increases file size. For videos with minimal motion changes, a GOP value between 90 and 250 is often sufficient. For videos with frequent scene changes, high motion, or intended for post-processing, a typical GOP value falls between 30 and 60.

The default output folder is C:\Users\PC\Videos\Winxvideo AI. Click the "Browse" button to select a different disk.

5 Click Done and hit RUN to begin compressing video.

Winxvideo AI Common Settings
4-2. Customize the parameter settings

This program gives you full control over the parameter settings. By adjusting video codec, resolution, bit rate, frame rate, GOP, etc, you can also reduce video file size with acceptable quality.

Please be aware that the program is preloaded with pre-configured profiles with best balance in size and quality, you can rely on the profiles if you don't want to mess around with the settings. But if you are an advanced user, feel free to set the settings for your specific needs.

Option 1. Change Codec

Generally, advanced video codec delivers higher compression ratio and better image quality. For example, HEVC is superior to H.264 and VP9 is better than VP8. So for smaller file size but better quality, you can change video quality to HEVC or VP9.

1 Drag and drop the source video to the interface, or click "+Video" or "+Folder" to load the video you want to compress.

2 Go to the "Target Format", hit "Video", and choose "MP4 HEVC" as the output format.

3 Hit RUN to begin shrinking video size using advanced HEVC codec.

Note: You can also change the codec to VP9 if you are using WebM as the output format. Please make sure to check the box of hardware acceleration and not to check "Auto Copy" option at the right side.

Winxvideo AI Common Settings - codec

Option 2. Lower Bitrate

Video bitrate is closely related to the video file size. Higher bitrate makes better image quality but larger file size. Generally, you can lower the bitrate value than the default quality setting to compress video without perceivable quality degradation. For a 4k video, the recommended bitrate is between 35mbps and 45mbps at standard frame rate and 53mbps and 68mbps at high frame rate. For a FHD 1080p video, the recommended bitrate is between 8-12mbps.

1 Drag and drop the source video to the interface, or click "+Video" or "+Folder" to load the video you want to compress.

2 Click the "Codec Option" where you can change the settings.

3 Drag the Quality slider to the left, which ensures faster processing speed and smaller file size, but produces relatively poor quality compared with the right.

Note: The target bitrate automatically changes as you move the quality slider. Optionally, you can manually set the bitrate to lower value by selecting "Manual" as the "Bit rate" mode, in such way to reduce video file size.

Winxvideo AI Common Settings -quality

Option 3. Reduce video resolution

Video resolution is the number of pixels in a video frame. The more pixels a video has, the more detail it will have and the clearer it will look. But a video of higher resolution such as 4K also involves in bigger file size and may be of no dramastic difference on a small screen like mobile phone compared with a video of lower resolution 1080. You can downsize video by lowering down resolution.

1 Drag and drop the source video to the interface, or click "+Video" or "+Folder" to load the video you want to compress.

2 Click the "Codec Option" where you can change the settings.

3 Find the "Resolution" under the "Video Codec Options" column, choose a video resolution lower than the original one from the drop down list.

Note: You are available to customize the video resolution by clicking the "Custom" button next to the "Resolution".

Winxvideo AI Common Settings -resolution

Option 4. Decrease video frame rate

Video frame rate, also referred to as FPS (frames per second), measures how many frames appear within a second. Higher frame rate generally results in smoother video quality. But when the frame rate is too high, especially in a video without too much motion, it will look unnatural and the video may suffer frame what is called the "Soap opera effect" and big file size. So you can decrease video frame rate to further shrink video.

1 Drag and drop the source video to the interface, or click "+Video" or "+Folder" to load the video you want to compress.

2 Click the "Codec Option" where you can change the settings.

3 Find the "Frame Rate" under the "Video Codec Options" column, choose a desired video frame rate as you want from the drop down list.

Note: Please uncheck the "Auto Copy" option from the right side.

Winxvideo AI Common Settings -fps

Option 5. Increase the GOP

GOP stands for group of picture. In video coding, it is a collection of successive pictures within a coded video stream. A GOP structure includes I-frames (intra-coded frames) and P-frames (predictive coded frames), as well as B-frames (bi-directionally predictive coded frames). Generally, a higher GOP value means more opportunities to compress, and therefore smaller the overall file size.

1 Drag and drop the source video to the interface, or click "+Video" or "+Folder" to load the video you want to compress.

2 Click the "Codec Option" where you can change the settings.

3 Find the "GOP" under the "Video Codec Options" column, choose a desired GOP value as you want.

Note: By default, the GOP is 250, meant to achieve a higher compression rate. If you have a video of low motion, you can leave the value unchanged. Generally, the value between 90 and 250 is OK. But if you have some videos of high motion such as some extreme sports, make sure to set the GOP value between 30 and 60.
