The algorithm is quite clever but can not produce the stunning video results which a dual-pass algorithm can because the encoder has no idea what video conditions will present themselves in the future. Constant Quality encoding is not suitable for streaming.Įncodes the video in a single pass aiming to maintain an average bitrate. Video size can not be adequately controlled or predicted when using Constant Quality mode, although quality can be. QP31 is excessively low quality producing almost total blocking, as the gains after QP22 are normally limited a recommended minimum quality is QP22 QP=1 is normally excessive, although it does produce near lossless video. The valid range for a QP in MPEG-4 is 1.31. A Higher QP will result in lower video quality, more compression and a smaller file. ![]() A lower QP will result in better video quality with a larger file. The QP (or Quantization Parameter) allows direct configuration of the video QP used. ![]() Encodes the video in a single pass with a fixed quality.
