#ADOBE PREMIERE 6.0 AVCHD IMPORT MP4#
they are actually first converting the MP4 info to a proprietary program format. I'd be VERY interested in such data or known/established info., if it mp3 compression is a constant compression technique the only thing that changes the compression ratio is the bitrate - which is not as complex like video which requires more complex techniques then audio to maintain quality. 1 RT - undetectible, 2RT - slightly noticeable in contrast or shadowing, 3RT - color fading, action begins to blur, 4RT - unrecommended or something of this sort.
I wonder if anyone has done a controlled test on this to determine a "rule of thumb" (i.e. Thus, an additional quality hit each round trip. In Video software, I assume now that VPX, like FCPX and Premiere Pro, they are actually first converting the MP4 info to a proprietary program format, and then re-exporting via an additional conversion process (so the MP4 is changed twice each time, rather than either remaining the same or being re-encoded identically).
mp3/.aac it does the exact same compression as the original process (unless I've added further audio processing, obviously). In Audio software, I can work with either the actual. I was hoping that MP4 video exported as MP4 video would similarly not take an additional quality hit, if the bitrate was the same.
What I've found encouraging on the audio side of things is that exporting an existing. aac or vice versa (which can sound truly terrible). I know what I'm dealing with when I compress a. This gets to the heart of what I wanted confirmation on. That depends on what the edit/render cycle is - these files are a compressed format and every time you re-render them you lose a bit of quality.
