Does anyone every get reduced amount of gain after rendering ??? Would it have anything to do with 24 vs 16 bit or the frequency ?? How do online sites such as Youtube, Facebook handle sound ..any ideas.
Did you look at your track effects? Vegas for some reason defaults with a few audio filters on in track effects. The compressor in particular will drop your gain some what.
The three FXs Vegas adds to the audio tracks by default do nothing at the default settings.
The bitdepth of the audio will have no effect on levels. The extra bits only effect the lowest level as binary 0 is 0dBFS, bigger numbers mean less level.
As for streaming sites such as Youtube, I haven't a clue and most of them don't say much about what they do to the vision much less the audio. Suck it and see is the best approach. The few things I've uploaded to Revver seemed to sound pretty much as they sounded prior to the upload, all else being equal.
In general your viewer is unlikely to be listening to Youtube through studio monitors in a quiet room so making it a bit louder (less dynamic range / a bit more compressed) can help.
How are you judging this reduced gain? There are any number of ways that the gain can change in various parts of the playback chain. I had one client that insisted that the levels were different between two of his media players until he figured out that the volume slider in one of them was set to 50% and the other was at 100%.
. . and before now, I have set my overall Windoze levels "low" too! Of course nobody ELSE would do such a silly thing - would they???
Another incident was a "Vegas" chum of ours who had completed all the work, finalized it all and produced that all important DVDA product, played it on his set-top DVD and got NO audio. After much high level sourincg of info from me, and testing and re-rendering and so on, he discovered a wayward LS audio lead coming from his set-top to his speakers - nasty!
As far as YouTube levels. My experience is, I had to have my output levels at about -3dB, if they went louder, YouTube will compress the quiet parts and it was very noticeable. My first try, had the levels to just barely beneath 0dB and the sound was very compressed (squashed). I did one at -2dB, that was ok, but now I use -3dB, just to be safe. (I couldn't really hear the difference between -2 or -3dBs)
Thanks for the feedback ! I uploaded this one to youtube for example
Later on I upped the volume and uploaded a follow up behind the scenes..it was better but I upped the gain using filters ..alot.
I'm still conducting a few more tests to find out. So far I couldn`t even upload to facebook ..error messages ..plus I recently got an rendering error using professional windows profile 9 ..who was it that said it was a good choice..anyways still working hard.
I should have specified that I was using an mp4, which is what YouTube asks for, for best quality. And my levels were for that mp4. I haven't tried with Windows Media.
