Keyframes Interval: Everything You Need To Know | Filmora

Many people may not understand what the Keyframe Interval stands for. However, it is a simple concept for video editors where the encoding settings determine the frequency at which the whole picture is transmitted.

The Keyframe Interval is responsible for how often a keyframe is generated within the video. A keyframe, also known as an i-frame, is a single frame that contains all of the necessary information for displaying a video. If the Keyframe Interval is set too high, it could lead to visible compression without compromising the quality of a video.

Keyframe Interval is essential in video streaming and recording, but it can be confusing. In this guide, we’ll help you understand this concept to enable you to create better animations.

Part 1. What Is Keyframe Interval

Keyframe Intervals, also known as “Keyframe Frequency” in Adobe Flash Media Live Encoder (FMLE) and vMix or “GOP size” by some encoders, is the frequency at which keyframes are generated in an animated sequence. This is an important parameter to consider when creating animations, as it can impact the animation’s file size, quality, and smoothness.

Keyframe Intervals are the distance in time between two keyframes. For example, if an animation is set to every 2 seconds interval and the frame rate is 30 per second, it means that every 60 frames, a keyframe is created.

Part 2. How Does Keyframe Interval Work?

Keyframes are important in video and animation because they mark specific points in time that can be used to create a smooth and consistent transition between different states or images. The Keyframe Interval is the amount of time that passes between two keyframes.

In order to create a smooth and consistent transition, the Keyframe Interval must be carefully calculated. In a 60-frame-per-second video, a keyframe is recorded every 5 or 300 frames. Delta frames are “difference” frames that provide an incremental change from the previous frame.

Keyframes are different from delta frames in that a higher keyframe value results in a clearer video with fewer transmission artifacts and vice versa.

The Keyframe Interval can be adjusted to create a faster or slower transition between two keyframes. A shorter Keyframe Interval will create a faster transition, while a longer one will create a slower transition.

For example, if you want your transition to look smoother, use a longer interval, like two seconds. Conversely, a zoom effect over a 0.2-second interval will be quicker.

Part 3. A concept closely connected to Keyframe Interval - Bitrates

The relationship between keyframes and bitrates is important to understand when creating video content. Keyframes are the frames in a video that are used to define the start and end points of an encoding process. The bitrate measures how much information is being transferred in a given time from one place to another.

When encoding video, keyframes are used to establish a consistent quality throughout the video. The bitrate is then used to determine how much information can be transferred without affecting the quality of the video. Thus, the higher the video’s bitrate, the better the quality.

Your mileage may vary regarding this explanation, as different encoders manage bitrates and keyframes in different ways.

For example, if you’re using an encoder like Wirecast, you might notice that broadcasting in a still background with someone talking results in a higher quality video as compared to a moving background. This can be reproduced using the same average bitrate and Keyframe Interval between them.

This happens because the delta frames have to share a lot more information to share in each frame in the video with a moving background. When you have an encoder like Wirecast, it’s working to keep your stream at an average bitrate. This can result in reduced quality if there is a lot of extra information in the delta frames.

Part 4. What You Need To Know To Set A Right Keyframe Interval

After understanding the important concepts in video editing, let’s see how to set the keyframe level in our videos appropriately.

Most streaming services will automatically set it for you based on your stream’s frame rate and bitrate. However, if you want to set the keyframe gap manually, there are a few things you need to keep in mind.

• Set the frame interval at 2 seconds. Do not increase it from 4 seconds.
• Disable the “auto” keyframe feature.
• To allow for b-frames, use an encoding profile higher than baseline and use IDR-based keyframes.

Part 5. How To Change The Keyframe Interval On OBS Studio

Above is the basic knowledge of the keyframe interval. Then, how to apply it to your real video-editing work? In this part, we will choose OBS to show you the application process.

OBS Studio is a powerful yet free and open-source screen recorder and live streaming tool for Windows, macOS, and Linux. One of the most useful features of OBS Studio is its ability to change the keyframe interval on the fly without having to restart your recording or stream.

The process for changing the it in OBS Studio has been made more efficient since the classic version. However, some users may have trouble locating the new setting.

Here’s how to change the it on OBS Studio:

Step1 Launch the OBS Studio on your PC or laptop.

Step2 From the bottom right of the screen, open the “Settings” menu.

Step3 On the Settings Window, click “Output” and configure the output mode to “Advanced.”

Step4 Finally, edit the Keyframe Interval, set it to 2 seconds, and click “OK” to save your changes.

Part 6. Will Keyframe Interval Affect Your Video’s Quality?

When you try to set the keyframe gap by yourself, you may feel confused about the difference a higher or lower interval make to your video. Then, wil-l or how it affects your video’s performance?

In a stream, it determines the balance between smoothness and picture quality. A keyframe is a point that determines how often the entire frame is sent, as opposed to just the differences from the previous frame.

Therefore, if you set the Keyframe Interval higher, your video will be more stable with fewer artifacts but requires more bandwidth and processing power. Conversely, a lower Keyframe Interval value causes more artifacts but is less resource intensive.

A lower Keyframe Interval value will result in lower video quality, while a higher keyframe value will result in higher video quality. However, the optimal Keyframe Interval value can vary depending on the specific case.

For instance, you don’t need a higher Keyframe Interval for streaming a live video, but you have to use a higher Key Interval value for recording.

So, without Wasting Time, Let Me Show You How to Mask a Video in Wondershare Filmora. Let’s Get Started

Masking is a video effect that allows you to cut out a scene and use the overlay to duplicate, hide, modify, or reveal your video footage. Just think of it as cutting something on your video so you can see what’s in the bottom layer. So, without wasting time, let me show you how to mask a video in Wondershare Filmora . Let’s get started!

Masking Trick 1:

First, you need to shoot footage to add the masking effect. To do that, find a doorway with enough space to walk back and forth before setting up a camera with a tripod facing the entrance. Make sure you set the camera at the center height of the door to prevent lens distortion.

With the tripod set up, film yourself walking behind the door toward the camera. Get close to the camera, then walk back to the door. Then, cross the doorway slowly before walking out of the frame. Now let’s get editing with Wondershare Filmora.

Step 1 Fire up Wondershare Filmora, then import the clip on the video editor. After that, move the clip to the timeline by merely dragging it. Add two clips on the first and second tracks.

Step 2 Now proceed to hide the first track before adding a freeze frame on the second track. To do that, move the playhead to find the starting scene with the door frame without your subject. Then, right-click the clip and tap Add Freeze Frame. After that, extend the freeze frame area and cut out the rest of the clip.

Step 3 Next, click the Effect button and find the Image Mask effect in the Utility folder. Now drag the effect to the top layer.

Step 4 Double-click the clip to open the video editing options, then choose a rectangle image mast under Video Effects. Ensure the mask is inverted by clicking the Invert Mask checkbox. Now adjust the mast to match the door frame before clicking Ok.

Step 5 Up to this point, unhide the first track, then find the scene where the subject appears on the door frame. On the first track, cut the clip before the subject appears on the stage before cutting the scene where the subject crosses the door frame for the second time on the second track. Now play the video to view your masking effect.

Masking Trick: 2

In the second masking effect, we want to create a subject walking in and outside a tree. To do that, find a tree with a clear background, then place your camera to film the center of the tree trunk where the subject will be walking.

Now film the subject walking from one side of the tree, stop for a second, and then turn back. They should repeat the same action, but this time they’ll walk forward outside the frame after the one-second stop. That’s all!

Step 1 Import the clip on Filmora, then add the footage on the first and second timelines. After that, hide the first track, then find the scene where the subject walks forward away from the tree in the second track. Cut off the area before that action.

Step 2 Next, click Effects, choose Utility, then drag the Image Mask effect on the second video track. Then, double-click the second clip, select Video Effects, and choose a rectangular option that masks the right side of the frame.

Now adjust the mask until it covers the entire right side of the tree. After that, unhide the first clip and move the second to match the first clip’s timing. You can also cut out everything outside the scene of the first clip.

Step 3 Play the video to see your subject walking in both directions of the tree.

Masking Trick 3:

For this masking illusion, we’ll create a video with a subject jumping over a house. So, set up your camera tripod on a low level in front of the building. You can also add a mark on the ground for your subject to know where to jump.

Now tell your subject to walk to the marker before jumping and walking out of the scene.

Step 1 Import the clip into Filmora and add it to the first and second tracks. Now hide the first track before finding the scene without the subject in the second track and add a freeze frame. After that, extend the freeze frame area and cut out the rest of the clip.

Step 2 Now, it’s time to customize the clip with a mask. To do that, head to the Utility folder under Effects and choose Image Mask. Click the Invert Mask box to invert the mask.

Step 3 Double-click the video track and choose an image mask under Video Effects. Note that you may need several combinations of masks to mask out the sky and leave the building. So, play around with different masking shapes until the sky is covered.

Step 4 After masking, unhide the first track on the timeline before playing the video to find the scene where the subject appears and cut off everything before that scene. Also, find the scene where the subject jumps in the air and cut the clip in the second track. Then, delete everything after that scene.

Step 5 Play the video to see your subject jumping over the building and walking away from the scene.

Conclusion

That was easy, right? Playing around with Filmora’s masking tools can create incredible masking illusions like the ones we’ve discussed. And don’t forget this video editor has many more creative possibilities. You should try these masking tricks!

First, you need to shoot footage to add the masking effect. To do that, find a doorway with enough space to walk back and forth before setting up a camera with a tripod facing the entrance. Make sure you set the camera at the center height of the door to prevent lens distortion.

With the tripod set up, film yourself walking behind the door toward the camera. Get close to the camera, then walk back to the door. Then, cross the doorway slowly before walking out of the frame. Now let’s get editing with Wondershare Filmora.

Step 1 Fire up Wondershare Filmora, then import the clip on the video editor. After that, move the clip to the timeline by merely dragging it. Add two clips on the first and second tracks.

Step 2 Now proceed to hide the first track before adding a freeze frame on the second track. To do that, move the playhead to find the starting scene with the door frame without your subject. Then, right-click the clip and tap Add Freeze Frame. After that, extend the freeze frame area and cut out the rest of the clip.

Step 3 Next, click the Effect button and find the Image Mask effect in the Utility folder. Now drag the effect to the top layer.

Step 4 Double-click the clip to open the video editing options, then choose a rectangle image mast under Video Effects. Ensure the mask is inverted by clicking the Invert Mask checkbox. Now adjust the mast to match the door frame before clicking Ok.

Step 5 Up to this point, unhide the first track, then find the scene where the subject appears on the door frame. On the first track, cut the clip before the subject appears on the stage before cutting the scene where the subject crosses the door frame for the second time on the second track. Now play the video to view your masking effect.

Masking Trick: 2

In the second masking effect, we want to create a subject walking in and outside a tree. To do that, find a tree with a clear background, then place your camera to film the center of the tree trunk where the subject will be walking.

Now film the subject walking from one side of the tree, stop for a second, and then turn back. They should repeat the same action, but this time they’ll walk forward outside the frame after the one-second stop. That’s all!

Step 1 Import the clip on Filmora, then add the footage on the first and second timelines. After that, hide the first track, then find the scene where the subject walks forward away from the tree in the second track. Cut off the area before that action.

Step 2 Next, click Effects, choose Utility, then drag the Image Mask effect on the second video track. Then, double-click the second clip, select Video Effects, and choose a rectangular option that masks the right side of the frame.

Now adjust the mask until it covers the entire right side of the tree. After that, unhide the first clip and move the second to match the first clip’s timing. You can also cut out everything outside the scene of the first clip.

Step 3 Play the video to see your subject walking in both directions of the tree.

Masking Trick 3:

For this masking illusion, we’ll create a video with a subject jumping over a house. So, set up your camera tripod on a low level in front of the building. You can also add a mark on the ground for your subject to know where to jump.

Now tell your subject to walk to the marker before jumping and walking out of the scene.

Step 1 Import the clip into Filmora and add it to the first and second tracks. Now hide the first track before finding the scene without the subject in the second track and add a freeze frame. After that, extend the freeze frame area and cut out the rest of the clip.

Step 2 Now, it’s time to customize the clip with a mask. To do that, head to the Utility folder under Effects and choose Image Mask. Click the Invert Mask box to invert the mask.

Step 3 Double-click the video track and choose an image mask under Video Effects. Note that you may need several combinations of masks to mask out the sky and leave the building. So, play around with different masking shapes until the sky is covered.

Step 4 After masking, unhide the first track on the timeline before playing the video to find the scene where the subject appears and cut off everything before that scene. Also, find the scene where the subject jumps in the air and cut the clip in the second track. Then, delete everything after that scene.

Step 5 Play the video to see your subject jumping over the building and walking away from the scene.

Conclusion

That was easy, right? Playing around with Filmora’s masking tools can create incredible masking illusions like the ones we’ve discussed. And don’t forget this video editor has many more creative possibilities. You should try these masking tricks!
