Tips for Getting Better Results When Fixing Compressed Videos
Even with an AI video enhancer, the quality of your source footage and processing choices can affect the final result. Keep these tips in mind before enhancing a compressed video.
Start with the Highest-Quality Source Available
Always use the highest-quality original file you can find. A video downloaded from a messaging app or social media platform may already have undergone additional compression.
Preview Short Clips Before Processing the Entire Video
Before enhancing a long video, process a short section first. Choose a section that contains different visual elements, such as faces, moving objects, fine textures, and dark areas.
Check the following details:
- Are the visible square blocks less noticeable?
- Do edges and textures look clearer?
- Are faces and other important details still natural?
- Does the enhanced footage contain flickering or artificial sharpening?
A preview helps you identify the right model and settings without spending time processing the entire video.
Avoid Excessive Sharpening and Upscaling
Increasing sharpness or resolution too aggressively can make a video look artificial. Excessive sharpening may create halos around edges, while strong AI enhancement can generate textures that were not clearly present in the original footage.
FAQs About Fixing Blocky and Compressed Videos
AI video enhancers can reduce visible compression artifacts, including blockiness, pixelation, noise, and blurred details. They analyze video frames and use learned patterns to improve image clarity.
You can use an AI video enhancer to reduce blockiness and improve the appearance of pixelated footage. Import the video, select a suitable restoration or decompression model, preview the result, and export the enhanced version.
Topaz Video AI can help reduce compression artifacts and improve degraded footage. Its Iris model is designed to reduce noise and compression artifacts, while Proteus and Artemis offer other approaches to general enhancement and detail recovery.
The best tool depends on your footage and editing experience. HitPaw VikPea is a practical all-around option for video restoration and decompression.
