This is typically implemented using multi-pass encoding, where one or more initial passes are used to collect data on the stream, and a final pass uses that data to achieve uniform quality at the specified average bitrate. We as videographers are too picky I think. We appreciate your help!

You will. for real-time encoding. The bits available are used more flexibly to encode the sound or video data more accurately, with fewer bits used in less demanding passages and more bits used in difficult-to-encode passages.[2][4]. If you can afford the time to render for 11 hours, then use 2-pass, why not? If up against a deadline and can't wait that long, then use CBR and get it done. Re: Is VBR 2 Pass that much better than VBR 1 Pass or CBR?by Oscar Gotti on Nov 17, 2015 at 2:14:36 pmOkay thanks, So if I understand correctly the only scenario where 2-Pass VBR would not give better quality would be when the bit rate is set to maximum? Unless you're working with Blu-ray surely this is very rare. COW Forums : Adobe Premiere Pro > . Single-pass VBR encoding is usually controlled by the fixed quality setting or by the bitrate range (minimum and maximum allowed bitrate) or by the average bitrate setting.
Media Encoder opened and I set my settings the following way: H.264 Blu-Ray 1440 x 1080 29.97 FPS PCM Audio Target Bit Rat = 18.5 Max Bit Rate 20 VBR 2 Pass When it first started encoding it said that it was going to take 8 hours. The user specifies a given subjective quality value, and the encoder allocates bits as needed to achieve the given level of quality. The disadvantage of this method is that the average bitrate (and hence file size) will not be known ahead of time. CBR tells the compressor it must use the same amounts of bits on every second of the film. ..

Walter Biscardi, Jr. Does this make it higher quality? Not really! The maximum bit rate will ultimately determine the quality of the output. Surely this is the same for whatever the size and length of the video? And why is it that the VBR file will be smaller? surely in your example if the bit rate is 10Mbps for both VBR and CBR the file size should stay the same? VBR will have the 10Mbps as the average, whereas the CBR will have 10Mbps as constant = same result?Return to posts indexReport Post.
