Does this make a difference?

[ImRyan]

so i was running an episode of a through handbrake and left the audio bitrate higher than the original file by mistake does this make a difference to audio quality

[Crunchy Dragon]

I think a higher bitrate is higher quality, but I could be very wrong.

[emosun]

no if it's higher

it'll effectively have the quality of the original files packed into the higher bitrate format

 

like stretching a low quality jpg out to a higher res , does nothing but make the file size larger

[KenjiUmino]

the file will be bigger than needed.

 

i avoid recoding where ever i can and usually set audio to "pass thru" if i want the same codec anyways ... like if the source file has AAC audio already and you want AAC audio on the output file then recoding it is BS

It won't make the audio any better or worse, it will just make the file size bigger.

My god EVERYTHING about this post is wrong.

 

Let me make something clear: Lossy compression is destructive, information is always and changed.  If you decode lossy data and then re-compress it to lossy again you will incur FURTHER change and less to the information, EVEN if you use a higher setting.  It's literally called 'Lossy' for a reason because there is LOSS in the process unlike LOSSLESS.

This covers JPEG but the concept applies to any form of lossy compression.

 

However, if you're transcoding video in Handbrake you should set the audio format to auto-passthrough, then it doesn't transcode the audio at all and instead just copies the data without decoding/encoding it again.
