A green screen is a fun way to create different backgrounds for your videos, but that isn’t all you can use it for. Using a chroma key tool, like the one in Filmora, you can add animations and transitions into your videos.

Say, for example, that you want to make a video where you’re hanging out with a CGI alien. All you need is an alien green screen effect – an animated alien against a green background. In Filmora, you drag that alien effect into your PIP track and switch the green background to transparent.

Your alien buddy will be overlaid over your main clip, which will make it look like he is there with you. Sound like fun?

Here are 4 YouTube channels where you can get green screen effects and animations for free.

YouTube Green Screen Stock Footage

GREEN SCREEN ANIMATION

This YouTube channel posts something new every day. Their effects include overlays, transitions, titles, and animations. Everything is free, but they do request that you link back to them in your video description if you monetize.

At GREEN SCREEN ANIMATION you will find lots of corporate and tech-industry effects, but they also have playlists of effects for makeup videos, military-themed effects, and animations inspired by movies (among other things).

BestGreenScreen

This channel specializes in action and sci-fi effects. Zombies, spaceships, and bullets are among their specialties, and many of their effects are inspired by movies like Star Wars. If you’re not into that kind of thing, they also have some nice overlays of things like mist or moving clouds. BestGreenScreen posts multiple times a week.

bestofgreenscreen

Bestofgreenscreen hasn’t posted anything new in a long time, but there is a huge existing catalog of free effects. There are a lot of action/military-themed effects (like explosions), as well as sci-fi and fantasy-themed things like dragons.

Beyond that, there are a lot of animals and nature-themed effects.

ALLDesignCreative

Here you’ll find things like fog, ripples, waves, and falling flowers – in short, overlays. There are lots of cool overlays included in Filmora, or available through our effects store, and if you go hunting through this and other free green screens/chroma key effect channels you can find even more.

Note: to obtain most of these effects, you will need to use a service that allows you to save/download YouTube videos.

One of the easiest ways to save videos is by using Save From. Just go to the watch page for the video and type ‘ss’ in front of YouTube in the address bar (so your address looks like http://www.ssyoutube ). You will be taken to a page where you can download the video for free, so long as you don’t want it in HD. You have to pay for the service if you want a higher quality clip, but most of these green screen effects will look fine in 720p.

Have you made anything cool recently using a green screen? We’d love to see it, share it in the comments.

Easy Way to Edit YouTube Videos in iMovie

author avatar

Richard Bennett

Mar 27, 2024• Proven solutions

iMovie is the built-in video editor that allows you to combine several video clips. It is available for both Mac and iOS devices. This app was first released in 1999 when it came with the iMac DV model.

With the use of the iMovie, you are able to create movies that include sound effects, menus, transitions, titles, themes, and music, just to name a few. The resulting movie can be saved onto physical media or as a file on the hard drive.

If you are a Mac user, then you can easily edit YouTube videos in iMovie. All you need to do is to follow the simple steps below. In this article, you will learn how to import videos, organize videos, add YouTube titles and add transitions.

Part 1. Steps on Editing YouTube Videos Using iMovie

To edit a video for YouTube with iMovie, you can follow these steps.

Step 1: Import Video Clips into iMovie

If you have recorded the video clips with the use of a videocam, then connect the camera to the Mac and open the app. You can import the videos by manually selecting the clips that will be part of the YouTube video.

Note: If you want to import videos that you have already published on your YouTube channel, then you can download them from the channel, and save them as MP4. However, if the videos were uploaded by other users, then you need to use a video converter, this article will let you know the 8 best video converters to convert video to MP4.

Step 2: Edit the Video Clips

Once you have all the clips that you need, the next step is to edit YouTube videos in iMovie. When you import the clips, you have created an Event in the app. If you want to include a clip in your final video, just drag the file to the project browser, where you can edit the video.

edit video clip

You can also add videos from other Events into the current project. You can select the parts of the video by dragging across the video from the chosen start to stop points. Edit the video until you are satisfied with the results.

Step 3: Enhance the Video

Once you have edited the video, you can then add background music, themes, sound effects, onscreen text, transitions between clips, and photos. The best thing about iMovie is that it comes with a sound effects library. It also allows you to upload audio from your iTunes library, iLife, and GarageBand.

iMovie allows you to add text to any part of the video, whether it is a title screen at the start, credits at the end, and everything in between. Try to enhance the video until you think it is ready to be uploaded to YouTube.

  • Add YouTube title : If you want to add a title for YouTube Video, all you need to do is click Title in the toolbar, and then highlight My Movie on the left. From here, enter the title you like.
  • Organize videos : You also can rearrange video clips in the timeline. Just drag the video on the timeline to wherever you want.
  • Add transitions : If you have more than one video clip, you definitely need transitions between them. Click the Transitions tab, and then select one transition you like. In the end, drag it to stop between two clips.

Step 4: Export and Upload the Video to YouTube

When you edit YouTube videos in iMovie, you have the option to export the video straight to the video streaming website. All you need to do is to click on the Share button found at the top of the screen. Then select YouTube. Add your YouTube account in iMovie by entering your username and password. Then you choose a title, description, and tags for the video.

You can choose the resolution and size of the video that includes HD 720p and HD 1080p, mobile, medium, and large. Click on Publish to upload the video to YouTube. Uploading the video will take several minutes to a couple of hours, depending on the resolution and size of the video.

Part 2. A Better Choice to Edit YouTube Videos

There’s a better way to edit YouTube videos. It involves the use of Wondershare Filmora . It is user-friendly and allows beginners to make videos professional-looking videos.

Download Filmora Win Version Download Filmora Mac Version

This software has more than 300 video effects for family, weddings, love, and travel, etc. You can also add animated captions to photos that will help tell the story. It comes with an array of intro and credit templates that will enhance your video.

Lastly, you can easily share the resulting movie on YouTube, DVD, other devices, and a lot more.
