Just about all of today's digital cameras are capable of recording video. Most are also capable of taking very good quality HD video. But a similar problem arises for most people in that it's not easy to view those video clips. Many would like to combine them to single playable videos, but don't know how. Similarly many others would like to create their own YouTube videos, but also don't fully understand where to start. This site's tutorials are intended to help those people. ONLY FREE SOFTWARE are used in these tutorials. That way, the average person can get started and try what they've learned immediately.

Video Special Effects - Part 3: Chroma Key and Movement Effects


Continued from Part 2.



The following video tutorial demonstrates how chroma-key and movement effects were incorporated into the above special effects video using VSDC Free Video Editor.  This includes the application of movement, zoom, and transparency effects to simulate a UFO approaching at great speed from a great distance.  Everything demonstrated in this video is summarized in the below article.  Each paragraph includes hyperlinks to specific sections within the video to help the reader follow these instructions with video examples.


Note that VSDC downloader will suggest installing additional bundled software along with VSDC.  This is why VSDC is free. Carefully read those installation screens and make sure to uncheck or decline any software that doesn't interest you (probably all). 
(VSDC download link click here).  





The UFO green screen effect is first placed on the screen by opening its video clip file from within the program.  It is placed on the work mat by holding down the left mouse button, and moving the mouse to roughly size the effect on the mat.


Now we apply chroma keying to remove the green color background from the UFO effect clip. Click on the Video tab. In the menus, select Editor / Video Effects / Transparent Background Remover.  If your background color is green, most of the color should disappear with this selection leaving a small residual ring around the perimeter of the UFO.  Keep in mind any background color can be made invisible (not just green).  If your background is different than green (say Blue), open the properties window, and click on "Get color from scene".  Use the eyedropper sampler tool to click on and set the invisible background color.

Removing residual color. If there is a residual ring of color around the UFO, in the properties window adjust Brightness Threshold, ChromacityU, and ChromacityV until it disappears.  This will require a little finesse and practice to best balance these three setting until the desired effect is achieved.  

With the background now invisible, we can now fine-tune the placement of our effect on the screen.  Click on the Scene tab, then click on and hold the mouse button down on the UFO effect.  Adjust its placement by moving the mouse.

A movement effect can now be added. Click on the Video tab above the timeline, then move the cursor to the beginning of the Video timeline.  In the menu, select Add Object / Movement.  Move the mouse cursor to where you'd like the movement to start, then hold down the left mouse button, and move the cursor to where you'd like the movement to end.  The speed of the movement can be adjusted by adjusting the length of the movement bar.  A longer bar = slower, shorter = faster.


We can use the Zoom effect to enhance the simulation of an approaching UFO.  We'd like our UFO to be small at the start, and as it gets closer, we'd like it to get bigger.  Click on the Video tab, and move the timeline cursor to the beginning of the Video timeline.  In the menu, select Video Effects / Transform / Zoom.  Adjust the Zoom timeline bar to the same length as the Movement bar.  Click on the Zoom bar, and then open the Properties window.  Set X, Y Start values for Zoom to 0, and X, Y End values for Zoom to 100.  This will make the UFO very tiny at the start of movement, and it will grow to full size at the end of movement.


We can also apply a little transparency effect to further enhance the effect of the UFO approaching from very far away. Click on the Video tab above the timeline, and move the cursor to the beginning of the timeline.  In the menu, select Video Effects / Transparent / Custom. Adjust the Transparency timeline bar to the same length as the Movement bar.  Click on the Transparency bar, and then open the properties window. Adjust Transparency Start to some mid value (such as 42) and End value to 100.  This will make the UFO semi-transparent at the start, making it somewhat hard to see at the beginning of its run.  But as it gets close, it will become more solid and more well defined.

  1. Was wondering what people were thinking of this series of tutorials? Do you all want more articles on advanced video editing with VSDC? Or some thing a little more basic with FileLab or Freemake? Please let me know.

  2. Hi. How do you make so the image from the green screen does not have Jaggy edges

  3. Chris, it takes a little fine adjustment of each of the three chroma key slide controls. For an example, click on the orange hyperlink above (in the article) that's labeled "Removing residual color".

  4. Hi, I can't get the green to go away. I have a background image spread out on the work area. I have my green screen video lying over the image. Both the video and the still image are showing down on the timeline. When I go to Video Effects / Transparent/, I can't click on Background Remover (or anything else) because they are greyed out. Can you help?

    1. OK, I was able to click Background Remover and I have the color of green chosen in Properties, but when clicking, the green background does not go away at all.

    2. Got a feeling that you applied chromakey to the image, and not the video overlay. As this program can edit many overlays, you need to tell it specifically which overlay to apply the effect.
      In the left column click on Scene, then click on your overlay video. Now look for its tab directly above the timeline labeled "Video: Video1". Click on this tab to let the program know that you wish to edit that particular video overlay. Now try "Video Effects/Transparent/Background Remover" again. Also recommend watching the second video above from 0:25 to 1:25 to see me more details on applying chromakey.

    1. I have the selfsame problem and have been trying without success to do this. I'm not a twit and I don't suppose you are either. Ass neither of us can do this, I am starrting to wonder if it's even possible with this software. In order to make avideo file with a transparent background, I believe tthat it must have an encoded alpha channel- ddenoted by a + sign. only some formats support the alpha channel, quicktime being one but for transparency , I think it has to be .mov+ annd not .mov . I can't see how to do this but really hope someone can and will tell us.

    1. Anonymous, click on the video clip on the timeline that you'd like to edit, then click on its tab above the timeline to open it. In the top main menu, click on Editor/Video Effects/Transforms/Rotate. Select "Whole Parent Duration" and click OK. The default rotation is 30 degrees, but you can fine tune the rotation in the right side properties window under Rotate Angles/All.

  16. Hi there, and thanks for this fantastic program. There is however one feature I did not succeed in implementing, and that is how to blurr faces or car plates for instance. I tried several approaches and failed miserably. Help needed, here, and thanks already for any advice.

    1. Well, for those interested, I finally found a way, do'nt know if this is the way to do it, but it works.
      Load a video, create a green ellipse place it on the face yo want to be blurred, then implement such movements to the ellipse in order to cover the face all the time (use movement and zoom).. convert the result to the exact format of the original video. Open a new project, load the original video, load the new one, remove the green background and blurr the original video. Convert the result, you have blurred what you wanted!
      Please somebody telsl me if there is a simpler and faster way to do it
      Thanks

Please comment on your experience or needs for video editing. I use such input for future blog posts. Also use the comments to contact me, as I read each and every comment. If I don't reply, that means I don't know the answer to your particular question, and hopefully one of the other readers can answer it.
