Particles is a beautiful effect you often see in music videos, sci-fi movies, and romantic clips. It’s a surefire way to create depth and achieve the desired atmosphere in a video. The most popular types of particles used for this effect are snowflakes, leaves, raindrops, and dust. However, any image can be used as a particle, including your own logo.

In this tutorial, we’ll show you how to apply the particle effect in VSDC Free Video Editor. It’s available starting from version 6.6, so make sure to download it from the official website.

Before moving to the text version of the tutorial, feel free to watch this video:

Once ready, visit the particle template gallery and download the collection you like. These templates are free, but you will only be able to open them in VSDC.

How to apply the particle effect in VSDC

To get started, import your video to VSDC and place the cursor on the timeline, right where you’d like the effect to start displaying. Next, open the Video effects menu, proceed to Nature, and select Particles – the effect layer will be added in a new timeline tab. From the right-hand side, you’ll see the Properties window: it contains three groups of settings you’ll be using to customize the effect.

The first group, titled Common settings, allows you to name the effect layer on the timeline, manually set the moment the effect appears in the video and the duration of the effect – in frames or in seconds.

The second group, Adjustments effect settings,contains one parameter: Transparency. Transparency defines the visibility level of the effect and can be either constant or dynamic. The latter means that you can gradually change the visibility of the particles, from transparent to non-transparent or back.

To apply the gradual change, you’ll need to use the parameters called Initial value and Final value. Keep in mind that 100 will mean that the particles are completely non-transparent and 0 will mean they are completely transparent. For instance, this is what the effect will look like if you set the Initial value at 10, and the Final value at 100.

The third group of settings is called Particle effect settings, and this is where you can change particle appearance and their movement style. We’ll take a closer look at this group of settings below.

How to select particle template

Once you apply the particle video effect, you’ll be able to change their size, movement speed and direction, quantity, and even position in the video. But first, you’ll need to select the type of particles you want to use. To do that, you’ll be using the Template groups and Template dropdown menus.

If you have already downloaded templates from the gallery, use the Browse icon to upload the template collection from your PC. If you have more than one collection uploaded, use the dropdown menu to select the one you need.

Each collection has several templates. In our example, the collection named “Seasons” includes snowflakes, green leaves, orange leaves, and waterdrops. Use the Template dropdown menu to preview the particles available in the collection.

You can upload your own image and use it as a particle as well. To do that, click the Browse icon located in front of Image.

Notice that the Image parameter also allows you to set the Maximum number of objects. This is not, however, the number of particles displayed in the video. The maximum number of objects is the parameter defining into how many pieces the original particle image will be divided. If the maximum number of objects equals 1, the entire image will be displayed. If you increase the value to 2, the original image will be divided into two parts, and so on.

Wind angle enables you to change the wind direction, which defines the direction of the particle movement. 

Wind strength affects the particle movement speed. The higher its value is, the faster the particles move.

The following parameter in the list of settings is called Linear movement and it has two modes: True and False. The former means that the particle movement will be linear and defined by the wind angle you’ve set up earlier. The latter means that the particle movement will be more chaotic.

Size of particle % and Maximum number of particles should be self-explanatory. Use these parameters to change the size and quantity of the particles displayed in a single frame.

The following parameter is called Use layers. It allows you to create depth and perspective by treating the three layers of the video – foreground, middle ground, and background – differently. If you activate the “True” mode, particles will be of different size on each layer. Plus, you’ll be able to blur and rotate them on the selected layers too.

Blur levels are applied to the particles located on the blurred layers and help you make them look less distinct.

Finally, the Rotate object option enables you to apply rotation to the particles. If you switch this parameter to “False”, there will be no rotation. If you activate rotation by switching to “True”, you’ll be able to set up rotation on each layer.

For amateur creators, the most obvious way to achieve a slow motion video effect is by reducing playback speed. However, this approach can be tricky. See, when you drastically reduce the speed of your footage, the video starts looking choppy. That’s quite disappointing.

In this quick tutorial, we’ll explain why simply reducing the playback speed is not enough to achieve a slow motion effect, and how to go about it using a feature called reframing.

Luckily, the new version of VSDC Free Video Editor includes two powerful reframing modes: Blending and Optical flow. So, before getting started, we recommend downloading it from the official website.

Watch the video tutorial to see how reframing works, and learn more about it below.

Why do slow-motion videos look choppy sometimes?

Suppose you want to reduce the speed of video playback from 100% to 10% of the original speed. When you do that, you technically reduce the number of frames per second – or the fps rate. And when you reduce the number of frames per second, you turn a video into stop-motion animation. The missing frames is what creates the stutter.

To help you visualize it, let’s take a gradient image as an example. An average video plays consistently, without hiccups; objects in the video move smoothly – just like the color transition in a gradient image:

When you reduce the playback speed to 10% (which is 10 times slower than the original video), you reduce the number of frames displayed per second by a factor of 10. That’s drastic. As a result, the video gets choppy. Going back to the gradient image metaphor, this is what it looks like:

To fix this and achieve a perfectly smooth slow-motion video effect, you’ll need to resort to reframing. Keep reading to find out what it is and how it works.

What is reframing and how does it work?

Reframing is an algorithm that allows for improving slow-mo videos with a low fps rate by creating additional frames.

There are three options available in VSDC Video Editor:

• Simple reframing
• Blending mode
• Optical flow mode

Let’s take a closer look at each mode.

Simple reframing is how your slow-mo footage looks originally without frame interpolation. It’s the default mode.

Blending helps you achieve a smooth slow motion video effect by filling the space between frames with duplicates and overlapping them in a proportion defined by the algorithm.

For those feeling geeky, here is how it works. The proportion in which frame duplicates will be overlapped is different at each moment in a video (see the illustration above). Suppose the cursor is moving from Frame 1 to Frame 2. If it has passed 30% of the way, the overlapping proportion will be the following: 70% of Frame 1 and 30% of Frame 2.

Since the cursor is still closer to Frame 1, the algorithm takes a major part of the image from that frame. As the cursor gets closer to Frame 2, the proportion will be changing. This approach is applied to every pixel of the video.

Optical flow is the most efficient reframing mode powered by artificial intelligence. In this mode, the software analyzes neighboring frames and, instead of duplicating them, it creates new unique ones.

Again, if you’re feeling geeky, the process looks as follows:

1. First, the software predicts what a frame between Frame 1 and the cursor would look like if it existed.
2. Second, the software performs a similar analysis for the space between Frame 2 and the cursor.
3. The result you see on preview is a blend of these two predictions.

So, what is the best way to create an impeccable slow motion video?

Now that you know enough about how speed reduction works in video and what reframing is, you can easily answer this question.

Reducing playback speed is almost never enough to achieve a good-looking slow-motion effect. Most times, you need to apply reframing. The reframing mode you should choose – as well as the result – always depends on the original footage. The higher its quality, the better the reframing result will be.

Remember that the video preview quality also depends on your PC power. If you have a low-spec computer, the preview may appear choppy. In that case, we recommend waiting until after you’ve exported the video to judge the result.

The new version of VSDC brings quite a few surprises, the updated Chroma Key toolset being one of them. We can’t be happier with the way it came out, and we’re sure you’ll love it too. The precision of chroma keying and the quality of the result is just outstanding, so even if you weren’t keen on removing backgrounds before, you probably will be after seeing how it works.

We suggest starting with this video tutorial about the HSL color space – the most exciting new feature in the Chroma Key toolset. Next, you can read the instructions covering the rest of the background removal properties.

If you haven’t downloaded VSDC 6.6 yet, you can do it here.

How to apply Chroma Key in VSDC

To get started, import your footage to VSDC, then open the Video effects menu and select Transparency - Background remover. The Object’s position settings window will pop up to indicate the point at which the Chroma Key effect should be applied to the footage. By default, the effect is applied from the cursor position to the remaining part of the file; if you’d like to change that – select the desired option and click OK.

Notice that once you apply the effect, you’ll be taken to a different tab on the timeline where the effect layer is located. The Properties window will slide-in from the right side – that’s where Chroma Key settings are located. If you can’t find the Properties window, right-click on the effect layer and select Properties from the context menu.

The Properties window contains three groups of settings:

1. Common settings
2. Adjustment effect settings
3. Background remover settings

Common settings allow you to add a title to the effect layer, change the moment when the effect appears in the video (by seconds or by frames), and the duration of the effect (in seconds or in frames).

Adjustment effect settings allow you to set the transparency level for the beginning and the end of the effect. This means you can either set a constant transparency value for the Chroma Key effect or you can have it gradually increase/decrease over time. To set the gradual change of the transparency level, you’ll be using the Initial value and the Final value. Keep in mind that 100% means full transparency and 0% means non-transparency.

For example, this is what the Chroma Key effect will look like if you set its Initial value at 100%, and the Final value at 10%:

Moreover, you’ll notice that many Chroma Key parameters provide you with the option to set the Initial value and the Final value as well. This means that if you want to set a dynamic background removal effect, you can do that, too. This feature comes in especially handy if the tone or the color of the background is changing during the playback.

Notice that the second line in this group of settings is titled Apply to source. “Apply to source” means that the changes will be applied directly to the original file you’ve uploaded – aka the source. By default, this option is deactivated to speed up rendering. If it’s deactivated, the software applies the chroma key effect to a scaled-down copy of the video. You should understand, however, that sometimes, scaling may lead to minor image corruption – especially, if the original file is not of the best quality. That’s why we always recommend using high-quality footage or, if you have a powerful PC, just switch this parameter to “True” and forget about scaling.

The last group of settings is called Background remover settings, and it allows you to fine-tune the Chroma Key effect parameters. We’ll take a close look at it below.

How to fine-tune Chroma Key effect in VSDC

In this part of the tutorial, we’ll go over the key parameters one by one and show you what difference each of them makes in the video.

The first parameter you want to look at is called Mode. Mode allows you to select the color space you want to work in.

In VSDC, you have three options:

• By YUV chromakey color – available in the free version of VSDC
• By HSL chromakey color – available in the Pro version of VSDC
• By chromakey mask – available in the free version of VSDC

The first two modes enable you to work in two different color spaces: YUV and HSL. The third mode named “By chromakey mask” is different. It enables you to upload an image to VSDC and use it as a mask to remove all the colors displayed in the image from your video. We’ll talk more about each mode in a moment.

If you select the HSL mode, you can also change Output. You should always use the “Composite” output mode unless you’re using Chroma Key to create a mask. In that case, switch to “Alpha-channel”.

The next parameter, Chromakey color, allows you to select the color for removal. We always recommend using the eyedropper tool and selecting the tone manually because the default bright green color may not coincide with the color of your background.

Notice that in the YUV mode, you can Add additional color if you need to remove more than one color from the video.

The rest of the background remover settings are displayed based on the mode you’ve selected: YUV, HSL, or “By chromakey mask”. Let’s take a closer look at each mode below.

YUV color space

You’ve probably heard of the RGB color space or encoding system. YUV is another tyfpe of encoding system which defines a color space in terms of three components: one luminance (Y) and two chrominances (U and V).

When you select the YUV color space mode, you can change the values of these components using the following parameters:

• Min/Max brightness (Y) threshold
• Min/Max chromaticity U threshold
• Min/Max chromaticity V threshold

These parameters are quite self-explanatory and they will help you remove the remaining green shades from the video if there are any. Each one defines the threshold for its own component. For instance, the color tones that are less bright than the minimum brightness threshold are removed from the video. In a similar way, the Min/Max chromaticity U threshold defines the threshold for blue color tones; the Min/Max chromaticity V threshold defines the threshold for the red color tones.

To visualize YUV color space in this context, imagine a three-layer cube where the minimum values form the deepest layer – the smallest red cube. Colors that fall into the space of the red cube will be removed from the video. The maximum values form the outer layer and the color values falling into this space will remain unchanged. Finally, the color values between the minimum and maximum are displayed as a spectrum of tones based on the effect transparency level you set up earlier.

If all three components (Y, U, V) are equal to 0, no chroma key effect will be applied to the video. If all three components are set to maximum, you’ll see a black screen because all color values will be removed.

Note that if you switch Adaptive alpha from 'False' to 'True', you’ll activate additional parameters that will help you achieve better results:

• Similarity value – this parameter sets possible color tone deviations. If it equals 0, the software will only remove the tone you’ve selected with the eyedropper. If you increase the value, the software will remove the tones that are close to the selected one.
• Blend value – this parameter helps you smooth the border of the object after the background has been removed. The higher the value is, the smoother the border will be.
• Kernel size – this parameter also helps you make the border of the object look smoother. The higher its value is, the larger border area will be edited.

HSL color space

HSL stands for Hue, Saturation, and Luminance (or Lightness). This color space is a Pro-level feature and it’s much more efficient at removing video backgrounds. Once you remove the background color using the eyedropper, the HSL parameters will help you achieve even better results. Let’s see how its parameters are different from the YUV mode.

Hue delta/Max Hue delta is a pair of parameters that sets a range of chroma key color tone variations based on their Hue values. The correct way to work with these parameters is to set Hue delta at 0 and start slowly increasing it until you see that most of the background is removed. Next, you should start increasing Max Hue delta to a value approximately twice as high as Hue delta making sure that you’re only removing the colors you want.

Lightness delta/ Мах Lightness delta – similarly, this parameter sets a range of chroma key color tone variations based on their Lightness values.

Saturation delta/ Max saturation delta sets a range of chroma key color tone variations based on their Saturation values.

Reduce contrast allows you to change the contrast level of the chroma key color (which is the color of the removed background). It’s convenient if you want to see the difference created by the effect, however, the value of this parameter doesn’t affect the resulting video.

The way Chroma Key works in the HSL color space is different from the way it works in YUV. Essentially, when you apply HSL, you create a mask by keying out the selected background color and making that space in the video transparent. To see the “mask”, switch Output to Alpha channel. The mask will look like a black-and-white image where the black space is the removed background.

Take a closer look at the borders of the mask: it’s usually rough and uneven. Because of this, the video may look unprofessional when you replace the background with another image or footage. To fix it, you can apply up to 6 chromakey post-processing filters designed to smooth the border.

The filters are customizable. That means you can select their modes manually based on what you’re trying to achieve. Here are the modes available for each filter:

• Maximize filter – this filter analyzes the area around each pixel and applies the maximum value to it.
• Minimize filter – this filter analyzes the area around each pixel and applies the minimum value to it.
• Median filter – this filter analyzes the area around each pixel and applies the median value to it.
• Blur filter – this filter applies the median value to the pixels forming the border of the mask.

Each filter has two more parameters: Level (the size of the analyzed area) and Stage order (the order in which filters are applied).

Even with all filters having the same value, just by changing their order, you can achieve drastically different results:

By chromakey mask

The third Chroma Key mode in VSDC is called “By chromakey mask”, and it’s significantly different from the previous two modes. In this mode, you manually upload an image containing the colors you want to remove from the video; the software detects the image colors and keys them out.

Here is how it works:

1. Switch to “By chromakey mask mode”.
2. Upload a “Chromakey mask” – an image containing the colors that need to be removed from the video.
3. Now, the software will compare the image and the video and remove all the coinciding colors from the video.

Once you do that, you can go ahead and tweak the parameters to achieve better results. Some parameters are similar to those in the YUV mode. So we’ll take a look at the unique parameters only:

Mask resize factor – this parameter allows for reducing the size of the uploaded image to speed up analysis. The higher its value, the smaller the image size is (which means there are fewer pixels to analyze). However, you should understand that the smaller the image is, the less precise the analysis will be, and that may affect the quality of color removal.

Resize mode – this parameter enables you to select one of the 5 image resizing modes:

1. Nearest neighbor interpolation
2. Linear interpolation
3. Cubic interpolation
4. Supersampling interpolation
5. Lanczos interpolation

Time to add a new background

Whichever approach you choose to remove the background from your video, the most existing part is probably adding a new background which can be both a video or an image. Go back to the main timeline tab and use the Add object menu from the top of the interface to select the desired file from your computer. Then manually place the new background one layer below the chroma key mask as illustrated below.

Use the preview feature to make sure everything looks good. Remember that you can go back to the Chroma Key settings at any moment if you need to make adjustments. Just double-click on the green screen video to access the background remover effect layer and use the Properties window.
