Metric value is shift in frames of distorted sequence relative to original. If n-th value is x, then n+x’th frame of distorted corresponds to n’th frame of original

Algorithm description
This metric performes calculation of another metric (base metric: PSNR or SSIM) between each frame of original image and several frames of distorted image. You can choose what interval will be used in settings. This metric can detect such artifacts as skipped frame, duplicated frame, small fps mismatch.
Metric considers, that the best metric value for specific original frame is the correct shift. Metric can prefer smaller shift with base metric value X to bigger shift with metric value Y if , where threshold can be set in metric settings. This helps to avoid random fluctuations.
Also, values of base metric will be smothed over adjacent frames if smoothing is on. This can help in case of very there are very similar adjacent frames in seuqence or the desired frame is absent (for example, negative shift on first frame).
