HitFilm为电影提供了丰富的效果。 将来自iClone的素材与HitFilm中的素材相结合,可以提升效果,颜色分级等多种渲染素材。 HitFilm和iClone为视频退伍军人或首次电影制作人员提供可以以最少并发症完成各种令人满意的镜头的工具。

iClone是一款用于创建动画电影的3D软件,但有时候您还需要添加一些额外的效果,才能真正将场景带入生活。 幸运的是,HitFilm让我很容易,我在这里向你展示如何使用。

我们将要讨论如何使用HitFilm在即将到来的粉丝电影“星球大战帝国”的一个关键场景中添加一些强力闪电效果。

HitFilm provides a wealth of masterable effects for films. Combining footage from iClone with editing in HitFilm can enhance a rendered clip with excellent effects, color grading and more. HitFilm and iClone enable video veterans or first-time filmmakers with tools that can accomplish a variety of satisfying shots with minimal complications.

iClone is a great piece of 3D software for creating animated films, but there are times when you'll want to add some additional effects to really bring your scenes to life. Fortunately, HitFilm makes that easy and I'm here to show you how.

We're going to be talking about how HitFilm was used to add some force lightning effects into a key scene in upcoming fan film, Star Wars Imperials.

Step 1: Planning your effects

Before we begin with HitFilm, we want to take a good look at the scene in iClone and ask ourselves, what can we do here that will make the effect look better and more believable. Since the effect we'll be adding is lightning, we'll want to light up the surrounding characters and objects. We'll achieve this by placing spotlights near the source character, a point light above the scene, and attaching another spot light to the target character.

步骤1:规划你的效果

在我们开始使用HitFilm之前,我们想看看iClone中的场景,并问自己,我们在这里可以做些什么,使效果看起来更好,更可信。 由于我们添加的效果是闪电,我们想要点亮周围的人物和物体。 我们将通过将射灯放置在源字符附近,场景上方的点光,并将另一个聚光灯附加到目标角色来实现。

It only took a few minutes to add and position these lights, but that was time well spent as it will make a huge difference when we add the lightning. While not every effect is going to light up your scene, it's worth thinking about how else it might have an impact, and seeing what you can do in iClone to make it look more convincing.

这些灯只需要几分钟的时间才能添加和定位,但是花费的时间很长,因为在添加闪电时会产生巨大的变化。 虽然并不是每一个效果都会使您的场景变得光亮,但值得考虑的是它可能会有什么影响,并且看到您可以在iClone中做些什么来使其看起来更有说服力。

Step 2: Import your footage

Once you've completed your scene, you'll need to import it into HitFilm. Create a new project in HitFilm and from the media tab, click the import button. From here, select your video file and click open. Finally, drag your footage onto the timeline.

步骤2:导入您的素材

完成场景后,您需要将其导入到HitFilm中。 在HitFilm中创建一个新项目,并从媒体选项卡中单击导入按钮。 从这里,选择您的视频文件,然后单击打开。 最后,将您的素材拖到时间轴上。

Now that you've got your footage ready, the next step is to go through and break it up into smaller clips. You can use the slice tool for this and ideally you want a cut every time the camera cuts to another angle.

现在你已经准备好了你的素材,接下来的步骤是将其分解成更小的片段。 您可以使用切片工具,理想情况下,每次相机切割到另一个角度时,都需要切割。

When that's done, select the first clip and click on "Make Composite Clip". This creates a mini project for just the chosen clip, and it's here we will add the effects we want.

完成后,选择第一个剪辑并单击“制作复合剪辑”。 这将为所选剪辑创建一个迷你项目,在这里我们将添加我们想要的效果。

Step 3: Motion Tracking

While you could begin with playing your effects right away, there's a very useful tool that will save you a huge amount of time, it's called motion tracking. This allows you to highlight a certain part of the frame, such as an object, and HitFilm can track how it moves through your video clip. We'll be using it to track the hands of the character casting the lightning effect.

步骤3:运动跟踪

虽然你可以立即开始玩你的效果,但是有一个非常有用的工具可以节省大量的时间,这就是所谓的运动跟踪。 这允许您突出显示框架的某一部分,例如对象,HitFilm可以跟踪它如何在视频剪辑中移动。 我们将使用它来跟踪闪电效果的角色的手。

elect the video clip on the timeline, then from the controls tab, click the insert tracker button, as indicated on the screenshot above. This will place red and green squares on the video footage. The red square highlights what you want to track, the green square tells HitFilm where to look for it. Both squares can be resized and repositioned as you need to. The faster the object is moving, the bigger you'll want the green square, but don't make it too big as it may track the wrong object by mistake.

In the screenshot below, you'll see we've zoomed in close and placed the red box around the character's left hand, with the green box placed around it. When you're ready, click the track forward button, as highlighted in the screenshot, and HitFilm will go through your clip, tracking the object it detects in the red box.

在时间轴上选择视频剪辑,然后从控制选项卡中单击插入跟踪器按钮,如上图截图所示。 这将在视频片段上放置红色和绿色的正方形。 红色方块突出显示您想要跟踪的地方,绿色广场告诉HitFilm在哪里寻找。 可以根据需要调整两个正方形的大小并重新定位。 对象移动越快,你想要的绿色方块越大,但不要太大,因为它可能会错误地跟踪错误的对象。

在下面的屏幕截图中,您将看到我们已经放大了一点,并将红色框放在角色左手边,绿色框放置在左边。 准备就绪后,单击轨道前进按钮,如屏幕截图中突出显示的那样,HitFilm将通过您的剪辑,跟踪它在红色框中检测到的对象。

Occasionally you may find the tracking goes off course. To correct that, find the frame where it goes wrong and drag the red square back into the correct position. You may need to adjust both squares, depending on how the tracked object changes shape in your scene.

In this particular scene, we will be repeating this process twice more, once for the right hand and once to track the target of the lightning. After that, for every tracker you have, you'll need to create a point layer. Then go through each of your trackers and from the layer drop down menu, choose one of those points. Each tracker needs its own point and I like to give them related names so they are easier to manage.

有时您可能会发现跟踪不合适。 要纠正这一点,找到出错的框架,将红色方块拖回正确的位置。 您可能需要调整两个正方形,具体取决于跟踪对象如何更改场景中的形状。

在这个特定的场景中,我们将再次重复这个过程,一次是右手,一次跟踪闪电的目标。 之后,对于您拥有的每个跟踪器,您都需要创建一个点图层。 然后通过每个跟踪器,从层下拉菜单中选择其中一个点。 每个跟踪器需要自己的点,我喜欢给他们相关的名称,以便他们更容易管理。

All of this sounds like it's an extremely complicated step, but it really just takes a few minutes.

所有这一切听起来像是一个非常复杂的步骤,但它只需要几分钟。

Step 4: The Effect

Now we can place the lightning effect. Create a new layer, then from Layer Properties in the controls tab, set the blend mode to "Add". This makes anything that's pure black transparent, while other colors will blend seamlessly into the video layer behind.

Switch over to the Effects tab and you will find a complete list of all the effects available to you in HitFilm. Lightning can be found under "Particles & Simulation", select the effect and drag it over to the layer you just created on the timeline.

步骤4:效果

现在我们可以放置闪电效果。 创建一个新图层,然后从控件选项卡中的图层属性,将混合模式设置为“添加”。 这使得任何纯黑色透明,而其他颜色将无缝融合到视频层后面。

切换到效果选项卡,您将在HitFilm中找到可用的所有效果的完整列表。 闪电可以在“粒子和模拟”下找到,选择效果并将其拖动到您刚才在时间轴上创建的图层。

The lightning is there but not in the right place. Go to the controls tab and from here we can adjust various settings to give us the effect we want. The first things we need to change are the start and end point settings. With the "use layer" setting, we can attach the lightning to the motion tracking points we set earlier.

闪电在那里,但不在正确的地方。 转到控制选项卡,从这里我们可以调整各种设置,以给我们想要的效果。 我们需要改变的第一件事是开始和结束点设置。 使用“使用层”设置,我们可以将闪电附加到我们之前设置的运动跟踪点。

You'll also need to set the start and end point coordinates to 0,0. This will adjust the position of the lightning, making it appear from the character's hands and striking the target character.

您还需要将起点和终点坐标设置为0,0。 这将调整闪电的位置,使其从人物的手中出现并触及目标人物。

It still doesn't look quite right though, the lightning is wider at the source, even though it's further away from the camera. If we change the start width setting to 0.05 and the end width 0.15, we can fix that.

它仍然看起来不是很正确,但闪电在源头上更宽,即使它远离相机。 如果我们将起始宽度设置改为0.05,结束宽度为0.15,我们可以解决这个问题。

It's already much better, but we're not quite there yet. Force Lightning in Star Wars is much more direct, while our lightning effect is arcing far too much between the two characters. We can change that by adjusting the wave scale setting to 0.1.

We're almost there; we need to add several more bolts of lightning. A simple matter of using the trunks setting. It's currently on 1 but changing that to 3 gives us more. It can go up to 50 but that seems a little excessive for this particular shot.

这已经好多了,但我们还没有到。 星球大战中的强力闪电更直接,而我们的闪电效果在两个角色之间的电弧太大了。 我们可以通过将波形设置调整为0.1来进行更改。

我们几乎在那里 我们需要增加几个闪电的螺栓。 使用树干设置的一个简单的事情。 它目前在1,但改变为3给了我们更多。 它可以上升到50,但对于这个特定的镜头来说似乎有点过分。

What we want to do next is duplicate the effect, so we have lightning appear from both hands. Rather than go through all this again, simply right-click on the effect under the controls tab and select duplicate.

You'll need to adjust the start point on the new effect to the other hand so it's not quite emanating from the same position. You'll notice the lightning looks like it's an exact copy, which isn't very realistic. Fortunately, we can change the seed setting to give the lightning a different pattern.

我们接下来要做的是复制效果,所以我们有双手闪电。 而不是再次通过所有这一切,只需右键单击控件选项卡下的效果,然后选择重复。

您需要在新效果上调整起始点,否则不会从同一位置发出。 你会注意到闪电看起来像是一个精确的副本,这不是很现实。 幸运的是,我们可以改变种子设置,给闪电带来不同的模式。

And that is how you add a lightning effect to your scene. There are many more options that let you change the shape, the color, the way it's animated and so forth. Every effect available in HitFilm has a lot of options, so you can customize them to suit your scenes.

那就是如何在你的场景中添加闪电效果。 还有更多的选项可以让您改变形状,颜色,动画方式等等。 HitFilm中提供的每个效果都有很多选择,因此您可以根据场景进行自定义。

Step 5: Keyframing

The lightning effect is in our scene, but at the moment, it exists throughout the entire clip, even before we want it to be visible.

步骤5:关键帧

闪电效果在我们的场景中,但在这一刻,它存在于整个剪辑中,甚至在我们希望它可见之前。

We're going to use Keyframing to hide the effect until we need it. Scrub through your clip until you find the first frame you want the effect to be completely visible. Then, under the controls tab, find the Growth setting for the lightning's end point.

我们将使用Keyframing隐藏效果,直到我们需要它。 擦过你的剪辑,直到找到你想要的效果完全可见的第一帧。 然后,在控制选项卡下,找到闪电终点的增长设置。

Click the circle next to it to enable keyframing for this setting. This will save the current value of 1.00 for this particular frame. Scrub back through the clip to where you want the effect to be invisible, set the growth value to 0. HitFilm will then automatically fill in the difference between these two keyframes, making the lightning appear to leap out of the character's hands and hitting his target. You can use keyframing on almost every setting, so your effect can be made to change as your scene progresses.

点击它旁边的圆圈启用此设置的关键帧。这将保存该特定帧的当前值1.00。将剪辑刷回到您希望效果看不到的位置,将增长值设置为0.然后,HitFilm将自动填充这两个关键帧之间的差异,使闪电似乎从角色的手中跳出并击中目标。您可以在几乎每个设置上使用关键帧,因此可以随着场景的进行而改变效果。

Step 6: Enhance your scene with additional Effects

We've finished all of the work on the lightning effect, but it looks a little out of place. What we can do here is enhance it with some additional effects. These will help it blend in and add a little more realism to the scene. Using much of the same process described in Step 4 and 5, we're going to add some light flares. One on the source character's hands and the other on the target character, to give the appearance of a powerful impact.

There are a lot of different types of flare but for our scene, we want to use Digital Blocks for the hands and Anamorphic Streak for the impact. We'll tie these to the left hand and target trackers, so that they move with the scene.

步骤6:增加您的场景与额外的效果

我们已经完成了所有的闪电效果的工作,但它看起来有点不合适。我们在这里可以做的是增强它的一些额外的效果。这些将有助于它融合并添加一点点现实主义。使用与步骤4和5中描述的大部分相同的过程,我们将添加一些轻微的耀斑。一个来源人物的手,另一个在目标人物上,给予外观强大的影响。

有很多不同类型的闪光灯,但对于我们的场景,我们要使用数字模块的手和变形条纹的影响。我们将把它们与左手和目标跟踪器进行绑定,以便它们与场景一起移动。

For this scene, I found both flares were a little too bright, so I lowered the intensity setting until I was happy with how they looked.

对于这个场景,我发现两个耀斑有点太亮了,所以我降低了强度设置,直到我对他们的看法感到高兴。

This only took a few minutes of extra time, but it was worth it to make the lightning feel more realistic and more powerful. To make your effects more believable take those extra few minutes and add the little details, even if it's a tiny puff of smoke. HitFilm gives you a lot of effects not just for big things like lightning or explosions, but for more subtle effects that can make your scenes feel more realistic.

这只需要几分钟的额外时间,但值得让闪电感觉更逼真和更强大。 为了使您的效果更加可信,需要额外的几分钟,并添加一些细节,即使它是一个微小的烟雾。 HitFilm不仅为闪电或爆炸等大事情带来很多效果,而且可以让您更轻松的效果,使您的场景更加逼真。
