Also, a 2 pass VBR encode will generally tend to be better than a 1 pass or a CBR encode, but will take longer and, depending on the type of motion, effects and transitions etc., in the video, may not be visually that much better. It is always good to reduce the calculated amount by at least 10% to 15% to allow for these fluctuations and audio streams.įor quality purposes, if you see the choice of CABAC or CAVLC entrophy encoding, use CABAC (for memory purposes, just think B is better). (converting gigabytes to megabits - 1000MB per GB and 8bits per Byte: 32GB x 1000 x 8 = 256000Mb )ĭividing the file size by the duration gives the bitrate:Īs Peter suggested though, 30Mbps is a better target to use, as the math I showed is very precise to make a 32GB file, and leaves no room for compression fluctuations, nor does it differentiate between audio and video bitrates. (converting hours to seconds: 2 hours x 60 x 60 = 7200s) With that equation and the bits to Bytes conversion factor of 8, we can figure out the required bitrate as follows Some of the earlier smart TV's were very particular about the file/container and codec.įor setting your bitrates in MPEG2 or MP4, (and for your future knowledge) the file size is dictated by this equation:ĭuration in seconds x bitrate in megabits per second = file size in megabits.

AVI will likely not be recognized by most TV's, and the Canopus/GV codec will almost assuredly be recognize by none of them.īest to use MPEG2 or MP4, but it might also help to know what the TV is so you can check the supported file/container types.
