H.264 - Codec / Deblocking

Deblocking is an important technique for improving the visual quality of compressed videos by smoothing out blocking artifacts caused by block-based encoding. Specifically, the libx264 H.264 codec uses deblocking to create a smoother and more natural image by optimizing the transitions between adjacent blocks. By fine-tuning the deblocking strength and parameters, you can achieve a balance between file size and image quality, significantly improving the visual quality of a compressed video.

Deblocking

Enable the loop filter

Deblocking Strength

The deblocking strength controls how intensively the deblocking is performed. A high value means more filtering of the block edges. Higher values ​​could blur the image.

Deblocking Threshold

Determines the threshold of the deblocking.
