How to Record Video Streams With FFmpeg on Windows and Mac?

FFmpeg is an open-source video processing tool with many powerful features. Many of these features are exposed through FFmpeg’s command line interface but can also be accessed from the program’s Python bindings and its Qt GUI frontend, called QFFMpeg.

This article will explain using FFmpeg command line tools to record video streams on Windows and Mac computers with step-by-step examples and screenshots.

Part 1. What is FFmpeg?

FFmpeg stands for “FF Multi-Platform Executable” and was originally developed by Fabrice Bellard in the year 2000 as an extension of the MPlayer project. The sole purpose of the software command-line design is to provide a complete solution for users to record live streams (audio and/or video) from any type of device that supports either the RTSP or HTTP streaming protocols.

FFmpeg is a complete, cross-platform solution to record, convert, mix, and edit audio and video files. The software has over 250 input formats, which allows users to record video streams in any media format. The FFmpeg commands stream the video back after recording, convert it into MP4 or MKV file, and process incoming data on the fly, such as rtmpdump.

Part 2. How to Record a Video Stream With FFmpeg on Windows?

The free FFmpeg command line tool is a great way to record a live internet stream and listen back to it later. If you have a Windows PC and want to record a video stream or screen using FFmpeg, our following step-by-step method will help you go through this process without facing many difficulties.

Step1 First, launch a browser of your choice on your Windows PC and head to the FFmpeg website. Hover over the Windows icon in the middle pane and select either the gyan.dev or BTbn build.

On the next screen, select the latest Windows 64-bit file from the list. Why? You need to use a computer compatible with the Windows 64-bit version. Next, download the ZIP file on your PC and use ZIP file extraction software to open the file contents.

Step2 Locate the ffmpeg.exe file on the extracted file and copy it to a new folder on your computer hard drive (e.g., C:\VideoRecorder).

Step3 In the next step, click the Start icon on your Windows dashboard and type cmd in the search box. Right-click on Command Prompt, select “Run as Administrator,” and launch the program.

Now, write the command to select the FFmpeg directory. For example, cd C:\VideoRecorder, and hit the “Enter” key.

Step4 To start recording the video stream, simply call FFmpeg and use the following command line. In this case, we are taking the example of capturing a YouTube video of “Running up that hill” from the top-rated TV show Stranger Things.

ffmpeg.exe -y -i https://www.youtube.com/watch?v=bV0RAcuG2Ao runningup.mp4

Hit the “Enter” key, and the output of this command will be displayed on the Command Prompt interface.

The command options have the following meanings:

-y allows automatic rewriting of existing files.

-i https://www.youtube.com/watch?v=bV0RAcuG2Ao is the stream URL that FFmpeg will record. You can change it with any video stream URL.

runningup.mp4 is the name of the output file.

Tips: Automatically Recording Video Streams on Windows PC

If you want your computer to record a specific video stream time automatically, use the Windows Task Scheduler to create a Timer to stop the recording after a particular time is passed.

Part 3. How to Record a Video Stream With FFmpeg on Mac?

You can use the Mac Terminal to record video streams via FFmpeg in the following way.

Step1 First, launch a browser on your Mac computer and head to the FFmpeg website. Hover over the Apple icon in the middle pane and select the macOS 64-bit static build option.

Download the ZIP file on your Mac and use ZIP file extraction software to open the file contents.

Step2 Launch the terminal on your Mac from the Apple menu, type the “ffmpeg -f avfoundation -list_devices true -i” command to let the system know which device to record from, and hit the Enter key.

Step3 Next, designate the path where you want to save your video, e.g., cd Path/to/my/videostream and press Enter.

Step4 Type in the “ffmpeg -f avfoundation -i “1:1”-c:v libx264 -qp 0-preset ultrafast out.mp4” command and hit Enter to start recording the video stream.

Stop recording the video stream by pressing “q.”

Part 4. How to Record Video Stream More Easily?

Sometimes, using FFmpeg to record a video stream on your Windows or Mac computer is too complicated. So, we recommend using Filmora Screen Recorder to make things a little easier for you.

A few benefits of using the Filmora Screen Recording software are as follows:

• Capture the computer screen and webcam at the same time.
• Select whether to record an entire screen or a part of it.
• Record your Windows or Mac computer audio and microphone voice at the same time.

Step1 Launch a browser on your Windows or Mac computer, install the Filmora Screen Recorder software, launch it, and select a New Project from the dashboard. Next, click the File option and select Record PC.

Step2 On the new Scrn pop-up window, customize the recording size by entering your desired dimensions. Also, choose if you want to record audio and which device to record it from.

Step3 Click Record to start recording the video stream. Once you are done capturing the video stream on the computer screen, click the F9 button to stop the recording.

Keyframes Interval: Everything You Need To Know

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.

Steps to Create One Click Video Reverse Effect in Filmora

All great video editors use phenomenal video effects in their videos. One of the most professional effects is the reverse video effect. This unique effect is always challenging for the makers to shoot and portray on the screen flawlessly.

At the same time, it is intriguing and always draws the audience’s attention. In this article, you will learn to shoot and edit the video for reverse effects using Filmora. But first, we will learn what does video reverse effect mean. So let us get into this!

Part 1. What Is Video Reverse Effect?

It is a special video effect in which a motion of things starts in the backward direction. This unique effect is used to intrigue the audience.

For example, if a bullet is fired from a gun. With the reverse effect, you can rewind the footage, and the shot goes back into the gun. So today, you can easily rewind fast action scenes and get a wow reaction from the audience.

Famous Examples of Reverse Effect in Films

1- Demolition of a Wall (1896)

Filmmakers first used this striking effect in 1896 in a 90 seconds film, “Demolition of a wall.” Louis Lumiere was the one who made that video. Below is shown an image from the film.

2- Tenet (2020)

It is a viral film by Christopher Nolan, which was a great success. He explained the concept of reverse entropy, in which you start moving back chronologically in time instead of forward. This concept is all shown through this special video reverse effect. Unfortunately, the audience had difficulty digesting this unique concept, which generated an awful response.

Part 2. How To Shoot Video Reverse Effect?

The reverse effect is unique, so special attention should be paid while filming a video. This section will cover some of the crucial prerequisites to film a video.

Steady Camera

It would be best to have your camera placed on a steady surface or mounted on a tripod stand to lock the focus. We will split the area and perform different tasks to make it look smooth. The audience will not get the idea that you completed the tasks separately. And it helps in the editing process as well.

A Spacious Area

You will need a spacious area in which you will perform different tasks. Make sure your camera stands still while shooting all the frames of video. In an ample space, it becomes easier to do movements freely. It also helps prevent glitches in the final product.

Splitting of Area into Portions

Now you have to split your area into portions. Each task is in its part of the frame, and actions in one frame should not pass over into another. You will do one activity per portion. It makes the editing process a lot easier. Finally, we get all three videos to merge and make it look like a single video.

After covering the prerequisites, we will now learn the editing process of creating a video reverse effect.
