i am done editing with vega pro 12 and now i want to render the video
i want an output exactly same as the input, not more nor less bitrate/quality.
but in vegas when i choose "AVCHD 1920x1080-50i" render template, and after even setting bitrate to 21,999,616 bps, my output video would have bitrate of approxiately 15414067 bps. how can i get same bitrate?
