Codec help
I am using final cut pro x with compressor. Is there a simple chart that gives MB per hour of video? I need a format for a web site at about 500 MB an hour of video and another format at about 3gb an hour of video.
I have a lot of video to render and I need to get this figured out first. Other than that, I have no clue what I am doing yet. I am just figuring this out. Thanks Russ |

Re: Codec help
Video quality is usually referred to in bits per second. Rough math suggests a bitrate of around 1000kbps for the smaller size and about 6000kbps for the larger. If set compressor to encode a video file (probably in H.264 for your purposes) the first tab on in the information window will give you an approximate file size per hour.
My math works like this: 500MB per hour / 60 minutes / 60 seconds = 0.138 MB/s X factor of 8 = 1.11 Mbps or 1,110 Kbps. If you know the final size, you can calculate the rate, and vice versa. Is this what Algebra was for??? :) |

Re: Codec help
If you have a Smartphone (I own an Android) you can download a bitrate calculator that will allow you to figure this out easily each time you need it.

Re: Codec help
I will always do a test export of one minute whenever I do long format video to which file size and quality constrains are important.Check the sample, do the math then final full video export.
