WebMar 1, 2024 · When you apply VBV to CRF encoding, the trick is to find a CRF value that, on average, results in your desired maximum bitrate, but not more. If your encode always “maxes out” your maximum bitrate, your CRF was probably set too low. In such a case the encoder tries to spend bits it doesn’t have. rachael harris smokinghttp://chineseoptics.net.cn/cn/article/doi/10.37188/CO.2024-0124 rachael harris night at the museumWebFor example, the hour of the day is a cyclical variable as it repeats every 24 hours.
