VQ Probe
Professional free tool for video quality measurement
The key usage model is to compare several implementations of the same codec standard or several different codecs
VQ Probe is a professional visual instrument for objective and subjective video quality comparison. It supports commonly used quality metrics, such as PSNR, SSIM, VMAF, and modern standards (AVC/H.264, HEVC/H.265, VVC/H.266, AV1, AV2, AVS3, MJPEG). VQ Probe allows users to compare different codec standards, build RD curves and calculate BD rates. It is capable of viewing YUV/Y4M files as well. Measure the quality of your videos with VQ Probe!
