1. Re: A question about bitrate.
Richard M Knight May 19, 2014 9:19 AM (in response to DanielFilming)1 I use a bit rate of 25 for the Blurays I make, the last one I did was very long and I had to drop it to 17, that still looked ok to me. UK Broadcast tv has a delivery spec. of a minimum bitrate of 50 but what is sent to your tv is a lot less.
2 CBR Constant bit rate- this encodes each frame at the same bit rate regardless of how complex the frame is. This encodes the fastest but produces the largest files.
VBR Variable bit rate- this adjusts the bit rate depending on how complex the video frame is, it allows a higher bit rate for complex sections that have lots of detail and movement. Single pass VBR has a guess on the fly when allocating the bitrate, it might not make best use of the bitrate. Two pass VBR looks at the video during the first pass and logs which sections need the highest bit rate and which sections need the least. This log information is then used during the second pass when the file is written.

DanielFilming May 19, 2014 9:30 AM (in response to Richard M Knight)Thanks a lot, Richard! I would still like some more info on bitrate for the video though. Maybe someone else knows something.
