Anytime you cut a clip with audio to trim it you unintentionally create a pop or click
but thankfully crossfades will fix this problem and davinci resolve just recently added the best
way to add a whole timeline's worth of fades that i've ever seen in a video editing program bam
it's that easy and it didn't undo any of the fade work i had done earlier in the editing
process so today we're going to do a quick and deep dive into everything that you need to know
about adding audio fades to smooth out your mixes you'll finally understand when and why you choose
one fade shape over another but make sure to stick around until the end to also learn a hack
for batch removing transitions in davinci resolve to use this new feature open the fairlight page
it has a music note go to the fairlight menu click the batch fade settings this box gives us
so much control but i love the overwrite existing checkbox the most leave this unchecked and it
won't undo any of the work that you've already done in the edit page this is so simple but so
useful because i'm generally not going to apply batch fades in the fairlight page until i'm close
to finishing editing my video this is a final finishing polishing step avid has this ability
but it doesn't have all this extra control that blackmagic has turn on all three orange switches
fade in and out are for clips that aren't touching another clip on the timeline
i like linear fade in and exponential fade out set to three frames you can also change the timeline
measurement to milliseconds instead of frames if you're more of a sound guy but i think in frames
exponential fade outs are a great way to get a gentle music taper now the middle crossfade
is for clips that are touching each other on the timeline these are good for frankenbiting
words together to help make a person sound more intelligent or concise than they initially sounded
maybe like me it's perfect for youtube style jump cuts but crossfades are also perfect for
transitions or ducking music background room tone and ambience that sort of thing
the one catch for crossfades is that you're going to need some handles that's the part of the clip
before or after the part that you see in the timeline it's just like a visual
cross dissolve just remember that adjacent clips need handles to create a transition
or you're going to end up with a warning choose equal power and set the length to two frames
two frames is usually enough samples to cover the zero crossing issue which i'll explain shortly
click apply and your fade settings are dialed in to batch add all of the fades you need to make a
selection i select the entire timeline by going to the first frame with a home shortcut key mark
i on the keyboard now choose the range selection tool r is the keyboard shortcut and click an
empty track header section this method lets you choose selections one track at a time but you
could also drag a marquee over all the clips easily with the range selection tool instead
now go to the fairlight menu and choose apply batch fades and your video is going to sound
so much better you can assign keyboard shortcuts to these commands by opening up
keyboard customization type batch into the search box click into the keystroke field i like to use
shift command f to apply fades and ctrl option command f to bring up the batch fade settings
so you're thinking great what's the big deal why should i care about adding fades to every single
cut let me briefly explain sound has an up and down waveform shape you probably already know that
and it crosses a middle line called the zero crossing if you cut on a zero crossing there's no
problem at all but in any video editing software that i've ever seen you can't cut on a zero
crossing because you're limited to video frames and not individual audio samples usually there's
48 000 audio samples in a second which is a lot more than 24 video frames in a second so if the
waveform gets interrupted by a cut and it isn't smooth anymore it creates a proper click when it's
played back some brilliant genius came up with the effect called the audio fade or crossfade
which smooths out the samples so that way there isn't a jump from one side of the cut to the other
the other way to fix a pop is actually by redrawing the waveform which you can surgically do
in fairlight but that's for another tutorial and not something you can batch super quick like fades
fades are like a quick band-aid so no one will be able to hear the cuts underneath
the other big question i always had was which type of crossfade should i pick under batch fade
settings there's two main presets there's equal power and equal gain honestly just stick to those
two ninety nine percent of the time and choose equal power sometimes called constant power pretty
much all of the time except for one exception this type of crossfade has a plus three decibel bump in
the curve to maintain perceived volume throughout the crossfade it has to do with the logarithmic
nature of sound falloff but just know this is the setting you want to pick most of the time
now only choose equal gain sometimes called constant gain for music loops and cues tone loops
anytime you could have a phase issue when they're combined you'll actually hear the bump and audio
if you choose equal power option when crossfading matching tones so just be mindful of this and
equal gain has your back in this situation batch applying fades is not new to davinci resolve but
having this kind of control and overwriting or not overwriting existing fades is new and it's
extremely useful but it needs to be done in the fairlight page if you're an edit page only guy and
you don't mind losing some of that control let me show you another way to apply fades very quickly
let's start by changing two settings open preferences go to the user tab click on
editing now change your standard transition duration to two frames when you start applying
video transitions you'll want to turn this up to at least six or eight frames so get used to
this preference location and save now let's tell davinci resolve what we want to use as
our standard audio transition on the edit page click effects audio transitions and right click
on crossfade plus 3db and choose set as standard transition the default is 0db which i would only
use for in and out fades but not for adjacent crossfades the plus db crossfade is the exact
same as the equal power that we looked at on the fairlight page i wish that blackmagic would use
the same terminology and if you're coming from avid this is your dissolve midpoint attenuation
just select all with command a and apply the crossfades with the shortcut on the keyboard shift
t this is my favorite add audio only transition is found under the timeline menu or you can right
click on the transition in the effects panel and choose add to selected edit point and clips
another quick tip to apply a single crossfade is to hold option and shift on the keyboard and then
click and drag one clip on top of another then if you want to center that transition up just
right click on the transition and choose center on edit but then if you want the crossfade to be
asymmetric you could hold command control on a pc and drag just one side of it with your mouse this
was new in 17.4 and i just want to show you that if you jump to the fairlight page for final mixing
you can see the crossfade effects have now turned back into our editable fade shapes and you can
click and drag the white dot around to customize it the edit page fade handles are doing the exact
same thing as the audio transition crossfade from the effects panel you just need one or the other
now before we get on to the bonus tip about batch removing fades i gotta say i'm so pumped
that you've taken the time to watch and learn i'm chadwick and this channel is called creative video
tips it's here to help you create videos that make a difference and stand out please help the channel
grow by subscribing and liking it so you don't miss out on next week's tips sometimes you just
need to delete every fader transition and davinci resolve does not make this obvious so here's how i
get rid of all of them in just a couple of clicks select all the clips with command a control on
a pc now drag any transition from the effects panel onto an existing transition this should
have just selected every transition and excluded the clips underneath now just tap delete on your
keyboard and they should be gone and since the time left on this tutorial is about to be gone
i'm gonna point you to this playlist right here if you want to learn more editing tips and tricks
in davinci resolve and because there is so much more to learn i will see you in the next video
