Hello everyone.
I'm almost a year into Vegas Pro 17. I've never saw a feature for a two pass encode like one will see in say Handbreak. I found the following information on the web concerning a two pass encode.
" What is two pass encoding?
Two pass encoding, also known as multi-pass encoding, is a video encoding strategy used to retain the best quality during conversion.
In the first pass of two-pass encoding, the input data from the source clip is analyzed and stored in a log file. In the second pass, the collected data from the first pass is used to achieve the best encoding quality. In video encoding, two-pass encoding is usually controlled by the average bitrate setting or by the bitrate range setting (minimal and maximal allowed bitrate) or by the target video file size setting. The best way to understand why this is used is to think of a movie — when there are shots that are totally, absolutely black, like scene changes, normal 1-pass CBR encoding uses the exact same amount of data to that part as it uses for complex action scene. But by using VBR and multi-pass, encoder “knows” that this piece is OK with lower bitrate and that bitrate can be then used for more complex scenes, thus creating better quality for those scenes that require more bitrate."
Now, I can't help but to think that the reason Vegas Pro has no 2 pass encode feature, per say, is because of it's allowance to set custom VBR settings.
Would anyone care to elaborate on my theory or just flat out rebuke my theory altogether? I'm interested in learning more. This Vegas form is, (from what I can tell), obsolete concerning this subject matter.
Thanks to all, in advance, for your time.
