Batch normalizing Audio in Videos...

[Handy]

Shutter Encoder is free for win and mac. its arguably the best converter for video. period. certainly the fastest on apple silicone.

this allows you to batch normalize videos audio.
You tube uses ..... wait for it.... -14 LUFS. And you should too.
They know what they are doing. Folks not using -14 LUFS ...Do not.



audio normalization > -14 LUFS > mp3 @ 256 @ 48k = same file size at the cost of an additional lossy encoding.

pcm @ 16 bit = almost double the file (for MST anyway 1 to 1.9 GB) so its not likely worth it to avoid another lossy encode for most folks.


They dont allow .flac in the audio normalization option. that sucks.
its not as sophisticated as studio one (300 $ with audio batch converter) which allows flack normalization for about +200 MB per average episode/film.
But its FREE and saves the multi stage process I have been using which involves extraction of the wav > studio one normalization > flac > insertion into mkvtoolnix > re exporting the .mkv.

Shutter Encoder does all this (except flac encode) in about 1 minute on m1 mac and in one step and in unlimited batches.
SUPER easy and fast. there is simply NO excuse to have audio levels allover the place and no reason to EVER adjust volume manually.


Lots of people usr this option to re-encode all their plex/kodi videos for a smoother experience.

So is that a better alternative to Handbrake? Or does it just excel at audio?

Nothing tops handbreaks quality for making video smaller in physical GB while retaining quality.
It's just a brutal cunt on the time it requires at high quality settings. 

I just realized this app does audio batch conversion
I use this mostly to convert video to .mov for insertion to the DAW.
My experience wit this app is minimal.
I don't think this app does the type of high compression handbreak does.
You wont get the quality of handbreak, even if it did.

Handbreak is the industry gold standard for what it does. Nothing beats it.
Adobe media encoder is a piece of shit by comparison. Even with all of Adobe's resources.

If you care about quality:
Never use anything but handbreak for reducing file size while retaining video quality.
Frame rate = same as source > very slow > RF -19 TO RF -22. 
set audio to pass through to avoid additional lossy compression.
Expect a long wait...
x265 takes about 3 times as long as x264 and 264 sucks by comparison to the quality of x265.
The difference is not subtle.

handbreak is a compression app for reducing file size. think of it as applying jpeg compression to the frame stack.
shutter encoder is a conversion app.
some of the formats happen to be smaller in size than your original at a quality loss.

In this case shutter encoder passes the video through with no encoding. only audio is encoded.

Nothing that goes fast will ever compete with handbreasks slow as fuk compression.
