How to Create YouTube Intros & End Cards - Free and Easy

Part1: Intros
Elements of an Intro
Intros should only last about five seconds, and that can be cut down to two or three if you have a larger following.
When your intro video is longer than five seconds viewers are more likely to click away. The first 15 seconds of a video is when viewers are most likely to decide to click on one of the recommended videos, or go back to their search results and choose something else. The odds of them leaving within these first 15 seconds are greater if you do not get right to the main point of your video. That is why long intro sequences are bad for your watch time.
Whether it is better to put your intro at the very beginning of your video, or after you introduce your topic, will depend on your viewers. You may want to try it both ways and then look at your retention report (found in your YouTube Creator Studio under Analytics) to see which works best for you.
Top Intro Sites
There are a few different sites where you can download animated intros, customized to include your username or logo. Here are two of the best:
FlixPress.com
This is probably the most popular intro site. There are a lot of great animated intros available for under $5, or even for free.
IntroMaker.net
This is another site with really professional looking intros for $5. They only have two free options, though.
Creating an Intro in Filmora
You can create a simple intro card in Filmora.
- Choose your background. You may want to use a short clip as your intro, or you may just want a colored background.
- Drag your clip or background into the video track of your timeline and trim it down to five seconds.
- If you have a logo, import it into Filmora and drag it into your picture-in-picture track.
- With your logo selected, click on the Green Screen icon. In the pop-up, select the background of your logo to make it transparent. For this to work your logo cannot be the same color as its background.
- Click on the editing icon with your logo selected and choose an animation.
- Go to the Text/Titles menu and choose an animated title that suits your channel. Drag it into your text track and edit it to include your name.
- The last piece of your intro is sound. You can choose a song from Filmora’s library and cut it down to five seconds, or import your sound effect.
- Export your video and save it for use in all of your other videos.
Part 2: End Cards
When your video ends, YouTube will recommend a selection of videos users may want to watch next. Often, these recommendations will not include more of your videos.
To keep viewers on your channel, you can create your End Card which recommends other content you have created.
Elements of an End Card
An end card includes clips from two or three of your videos, muted, and shrunk down to thumbnail-size. Using spotlight annotations you can make these thumbnails click-able.
It is also important that your end card includes multiple calls to action. A call to action is meant to spur a viewer to some kind of action. Writing ‘Check out this video’ above one of your thumbnails is a call to action.
You should also have a subscribe link somewhere in your end card, ideally a very noticeable button with a proven call to action like ‘Subscribe Now!’.
Some creators will leave their end cards at that and play music overtop, but it can be even more effective to include a voiceover where you ask viewers to subscribe and watch your other videos.
How To Make an End Card
- Choose a static background. You may want to download an end card template or create one in a drawing program. If you do, make sure to include calls to action like ‘Watch more!’ and ‘Subscribe’.
- Drag your background into your timeline at the end of your video.
- Import two or three of your previous videos and drag them into your picture in picture tracks. Each clip should be on its track.
- Trim the clips in your picture in picture track down to the same length as your end card.
- Shrink your clips down to thumbnail-size by dragging their corners in the preview window.
- Position your clips so they are spaced evenly by dragging them in the preview screen.
- Mute your clips.
- If your background does not include any calls to action, choose a title from the Text/Titles menu in Filmora and create at least two – one asking viewers to subscribe, and one asking them to watch your suggested videos.
- Export your video from Filmora and upload it to YouTube.
- Go to your Video Manager and select Annotations in the drop-down menu next to your video.
- Go to your end card in the previewer, as that is where you want to add your annotations.
- Click Add Annotation and add a spotlight annotation to your video. Stretch it over one of your thumbnails and then check the Link box under your Annotation’s timing. Insert a link to the video you are previewing.
- Repeat for any other thumbnails. For your subscribe button, change where it said ‘Video’ to ‘Subscribe’ and enter your channel URL.
- Click Apply Changes.

Snug Scenes for Snowy Screens: A Focused List
There’s something special about wintertime that makes us all want to get as cozy and as warm as possible. When you’re a YouTube creator, you should definitely take advantage of this desire and use a YouTube background video designed specifically with this in mind.
In this guide, we’ll go over how to get or make such a background and show you five incredible examples you can use now.
YouTube Video Background Creating realistic video scenes at your will is easy to complete with Filmora green screen removal.

What Is a YouTube Video Background?
A YouTube video background is a simple image or video that sits in place at the back of your videos. It’s just a simple background that can greatly impact your brand, presence, and style as a creator.
Even something as small as your YouTube video thumbnail background can strongly impact your results.
Obviously, choosing the right custom YouTube background is important. And, now that it’s winter, this requires a special approach.
Why Are Seasonal Backgrounds Effective?
There are several important reasons why a seasonal YouTube video background or photo, and other elements are very effective and engage us more.
The main reasons include:
- Creates a meaningful connection;
- Boosts engagement with fellow winter lovers;
- Builds a better brand;
- Enhances everyone’s mood, especially during the holidays.
So, whenever you can and whenever there is an opportunity, don’t be afraid to use a seasonal YouTube video background download.
Factors to Consider When Choosing a Background for YouTube Videos
Now, before we dive into the examples themselves and the tutorial on how to make the best backgrounds yourself, here are several factors you must consider before proceeding.
Content Relevance
As a video creator, you must ensure to be consistent with your elements. This includes your background tune for YouTube videos. For example, if you’re talking about books in your video, including a bookshelf in the winter background makes all the difference.
Audience Appeal
If you already have an audience, regardless of its size, you should definitely consider what they like and don’t like. You should then leverage this information to create highly appealing content for them and adjust your background scenery accordingly.
Lighting and Visibility
Another thing you must ensure is to keep your background simple and not too distracting. Remember, even though you have the best background for YouTube videos, you still need to realize that it’s not the main focus of the video. It’s just there to make it better.
Personal Branding
If you want to improve your brand identity and get your name known by more people, incorporate your logo, name, or something similar in the background. It will have a small but meaningful impact, and it’s easy to do.
Editing
If you plan to shoot a YouTube live background and not some stock images or videos, then you must make sure it has enough headroom for editing later on. The best option here is to use a green screen background for YouTube videos.
5 Winter YouTube Background Ideas
It’s finally time to have a look at some examples of highly effective and engaging YouTube video backgrounds for the winter season.
