A lot of people have asked me how to do the THOR Avengers' effect where his hammer
flies right into his hand that's actually pretty easy to do let me show you how
That's a meat tenderizer.
That's a hairdryer.
That's a lint roller
If you want to learn how to catch things that are kinda like Thor's hammer but not really...
Stick around, I'll show you how!
Ah! HELP!

So let me show you how I started. There's two different sections to this that you'll need to
understand how I kind of pulled it all together the first part is fairly simple
the second part is a little more involved and it talks about how to do
the thing that we've always wrestled with and that's Motion Tracking
Which you need for the Lightning effect to sort of follow the thing that's going
into your hand... and I'll show you how to do that but first of all let's take a look at the footage
Now, I'd like to convince you that I'm a great athlete
and I can catch things without really looking but nothing could be farther
from the truth. So let me show you what I really did.
I actually just filmed these things in reverse
I just held onto them and threw them away so if you look at
this footage knowing that... you can see I just grabbed this lint roller and tossed
it but when I tossed it I kind of kept my eyes forward so I wasn't tracking it
so much with my eye movement same with the hairdryer I don't even use a
hairdryer in real life that's pretty hard to work with that tool I looked
down I sort of assumed the position that I thought I would be in if I caught
something and then went backwards with it and this is just me throwing this
into a pile of pillows across the room with my girlfriend as a backstop now I
should mention that backstop doesn't always work because when I did this with
the meat tenderizer I managed to dent my floor it's not a real video unless
something gets broken but you can see it's just me tossing it away from myself
then in the speed and duration option I just used the reverse speed feature and
that flipped the footage around and made it play backwards now the next part is
kind of tricky and I really want you to pay attention here a lot of people have
asked me can you do motion tracking have something follow something within your
footage and film or currently doesn't have a motion tracking feature but I've
always said you can pull this off frame by frame if you're patient enough and in
this particular example because I'm using lightning which flickers and
doesn't have to be perfect it's a great one to show you how to do that so listen
this is what I did I found these lightning strikes from production crate
comm they have a mixture of free stuff and
paid stuff I found the free stuff so I could show you stuff you could readily
get right now but these are just lightning strikes that you can download
right now and use and their green screen effects now what you want to do is grab
one of those lightning strikes and drag it down into your timeline and put it
right on top of a piece of your footage where you're catching whatever object it
is that you're trying to catch I'm gonna do this one with the lint roller as you
can see it's a green screen element so if you double left-click on that and up
in the upper left you'll see in the videos tab if you scroll down you have
an option for chroma key click on that box put a check in it to activate the
chroma key but make sure you use the eyedropper and bring that plus mark over
to your footage and lay the + mark itself not the circle in a green area
that you want to use as your sample green this will tell filmora the actual
green that you should be removing from this footage now the green is gone but
the lightning strike is in here can you see it now this is what I did I scrolled
forward to where that lint roller actually made contact with my hand right
about there and then I moved that lightning strike so that it actually hit
right about the same time as the lint roller made contact with my hand I don't
know if that's the right thing to do it just felt right it looked right it
seemed arbitrary I was like that'll make sense let's do that now the lightning
strike is coming in at a weird angle so I want to change that a bit I'm gonna go
down to my lower left and lock my main footage so that it doesn't move click up
in the upper right and I'm going to move this rotate this footage cuz it looks
like it's coming in from the side I want it to come in from the top a little bit
so I'll move that over let me stretch this lightning strike out just a touch
and I want to rotate it so it looks like it's coming more down into my hand
that's a little bit better and I want it to hit right about in that crux of where
my thumb in my fingers come together right about in there that's pretty close
now to create this motion tracking what you want to do is again keep your green
screen footage of the lightning strike highlighted and right here in your
timeline with the time line stretched out as far as it'll go what you can do
by left-clicking in the timeline and dragging to the right or using this
little bar under your preview window to stretch it all the way out so yours
seeing frame-by-frame what's happening I'm now gonna slice that footage right
there and I'm gonna move forward one frame now you can do that by clicking on
the next frame or you can actually do that if you're highlighting your
timeline you can use your arrows on your keyboard to move forward one frame
let's move one more frame forward I'm gonna slice this again but I'm looking
at where this lightning strike is at now my hand has moved a little so I'm gonna
click up in the preview window and while I'm highlighting the lightning strike
I'm gonna use the arrow keys on my keyboard to slightly adjust this over so
it aligns up with the left side of this lint roller I'll now move one frame
forward I'll slice this footage again and you can see how the Lightning hasn't
moved with the roller so I'll click up in the preview window
again and I'll use the arrows to get that lined up with the left side of that
roller again and then I'm gonna move forward one more frame slice again click
up in the preview window and I'm gonna use the arrows again and I'll just keep
moving through this to get that lightning strike that little squiggle
lined up with the edge of the roller and just touching my hand and it ends right
about there you know hear that lightning strike doubles up at this point again
the arrow keys make this so much easier than dragging it around your screen
because when you use your mouse and you drag it around you can't get that really
fine-tuned motion that you can by using the arrow keys on your keyboard so I
always opt for doing that by highlighting and using the arrow keys
let me slice that last frame and I'm going to lose the rest of this I'll delete
it and let's take a look at how the lightning strike follows the lint roller
pretty cool huh? Let me scroll slowly through and you can see that lightning
strike hits in each frame I've got it moving with that lint roller so it
actually feels like we're doing some motion tracking now I also use some
other things like some sound effects and added some lens flares to really make
the screen kind of flash when the lightning bolt hit because just putting
that lightning bolt onto your footage looks a little bit cheesy but a real
lightning bolt if it hit would sort of light up the room so think about how you
can add some other layers in there to really help sell this
effect because once you pull it all together it should look something like this
