Even large 4K and HD videos that used to take hours now finish in just few minutes. The batch conversion feature lets you convert multiple files at once by making the process even more efficient.
AI-Powered Video Enhancement
One of most impressive features is the AI enhancement toolkit. The software includes over 19 AI models that can dramatically improve your video quality in multiple ways.
Video Upscaling: Transform low-resolution videos into sharp 4K or 8K quality. The AI analyzes each frame and intelligently adds detail to make old footage look modern.
Frame Interpolation: This feature reduces shaking and creates smooth motion by generating new frames between existing ones.
Colorization: Bring black and white videos to life by automatically adding natural-looking colors. It’s perfect for restoring old family videos and historical footage.
SDR to HDR Conversion: Convert standard videos to high dynamic range format for richer colors and better contrast.
Noise Removal: Clean up grainy or pixelated videos by removing digital noise while preserving important details.
Professional Editing Tools
The built-in editor provides everything you need to polish your videos before converting them.
Filters and Effects: Choose from variety of artistic filters including whirpool, HongKong movie, orange dots, purple, coordinates, warm, Stars, modern, gray and Sketch. You can also adjust basic properties like Contrast, Saturation, Brightness and Hue.
Subtitle Management: Add external subtitle files to your videos and sync them perfectly with the video. The delay feature helps you fix audio or subtitle tracks that are out of sync with the picture.
3D Video Creation: Turn regular videos into 3D format with anaglyph or split-screen options. You can adjust depth settings and switch left-right views to get perfect 3D effect.
Rotation and Flipping: Fix videos filmed sideways by rotating them clockwise or counterclockwise. Flip videos horizontally or vertically with single click.
Cropping and Trimming: Remove unwanted edges from your videos or cut them into smaller segments. The slider makes it easy to select exact portion you want to keep.
Merging Clips: Combine multiple video files into one continuous video. This is useful when you want to join different scenes or create compilations.
Video Compression Without Quality Loss
The AI Video Compressor reduces file sizes while maintaining visual quality. You can adjust the resolution, bitrate and sample rate to find perfect balance between size and quality. The preview feature lets you see results before finalizing compression.
The software compresses both video and audio files and gives you full control over output settings. You can rename files, change formats and specify exact size requirements.
Watermark Removal
Remove logos and watermarks from videos with just few clicks. Select the area containing the watermark and the software removes it cleanly. You can remove multiple watermarks at once or remove them for specific time periods in the video.
This feature is particularly useful for removing watermarks from TikTok videos, stock footage and other content where logos interfere with viewing experience.
Split Screen Video Editor
Create engaging split-screen videos that show multiple clips simultaneously. The tool includes various layouts and filters to make your videos more dynamic. You can place videos side by side, compare different angles or add reaction shots to your content.
Hands On: Aiseesoft Video Converter Ultimate
When I first opened the software, I was impressed by how clean the interface looked. Everything is organized logically by making it easy to find tools you need. The main window shows your video files and the conversion options are clearly labeled at the top.
I tested the conversion speed with 4K video file that was about 2GB in size. Using my mid-range graphics card, the software converted the file from MKV to MP4 format in under 3 minutes. The output quality was excellent and I couldn’t spot any difference from the original.

Next, I tried the AI upscaling feature on old 480p family video. I selected the Upscale Resolution option and chose 1080p as target. The AI took about 5 minutes to process 2-minute clip. The results were remarkable – the video looked significantly sharper and the AI did great job filling in missing details without making it look artificial.

The editing tools are straightforward to use. I added subtitle file to movie and used the Delay feature to sync it properly. The interface shows the delay in milliseconds and you can adjust it by dragging slider or entering exact value. I also experimented with filters and found that the HongKong movie filter gave my footage nice cinematic look.
One feature I found particularly useful was the batch conversion. I had 10 different video files in various formats that I needed to convert for my tablet. I added all files at once, selected MP4 as output format and clicked Convert. The software processed all files automatically and saved them to designated folder. The whole process took about 15 minutes for approximately 8GB of video.
The compression tool is another standout feature. I had large presentation video that was too big to email. Using the compressor, I reduced the file from 500MB to 150MB while keeping the quality acceptable for viewing. The preview window helped me find right balance between size and quality.
