Every year technology develops and gains new momentum, and more and more users use various tools to create incredible videos that gain a huge number of views. In case you are a programmer who wants to create video content while using various animation options, you should read this article.
Each programmer can easily write code or use existing code to create an interesting video without spending a lot of time and effort on it. The main rule in creating a video using code is that any image must fit into the memory array.
In this article, we’ll walk you through the proper way to create a video with code and walk you through the step-by-step guide and tools you can use to create an MP4 file.
Steps to Create Video From Code
Most users, even those who have a sufficient amount of knowledge in programming, are wondering how you can create a video using code. It is not as difficult as it might seem, it is only important to follow clear instructions and not make mistakes. Below you can find a brief description of the sequence of steps on how to create a successful computer MP4 file:
- First of all, you need to write C++ code with which you can create the necessary image in the memory array. Most often, programmers use the standard Mandelbrot Set file generator, but you can choose another one that is more convenient for you. This point must be approached with special responsibility because if you make a mistake at this stage, you will not be able to create a successful video at all.
- After that, you need to choose to use a library that will be open source, such as LodePNG, and use it to save your file in the required format on disk. The code will repeat these first two steps several times to generate the correct video frames. Each file that will be obtained will be the very frames for the video that you create.
- Next, use FFmpeg to convert all your finished images to MP4 videos. You can use Windows or Linux, in which case you will be able to create a successful file that will receive the video format.
With these simple steps, you can easily create an awesome video with code. It is important to remember that you should not forget about the sequence and try not to miss a single nuance in any case, by making one mistake you can sacrifice the success of the entire process of creating a file in video format.
Images of the Mandelbrot Set
One of the most popular fractal objects is the Mandelbrot set. With it, you can increase the set and get exciting shots. Such videos are often no more than 3 seconds long and have a speed of 30 frames per second. In total, these videos play approximately 900 files in quick order.
Image Generation in Memory
You can also use the GenerateZoomFrames function, which will help you create a series of PNG files. What you should be aware of is that each PNG image has multiple Mandelbrot images rendered at different magnifications. All images contained in frames have a resolution of up to 1280 pixels wide and 720 pixels high. These sizes are standard for HD 720p video material, but you can always crop video online and make it whatever you want.
Saving an Image to a PNG File
After you have created and generated all the images, you need to save them. You can use VideoFrame to help with this task. It is presented as just one frame from the video and helps to save the image as a PNG. You can use GenerateZoomFrames on a VideoFrame to generate each frame of your video and perform fractal zooming.
Use FFmpeg to Make a Movie
The last step in creating a video using the code is to run a special FFmpeg program with which you can convert all the received 900 PNG images into a complete file, which will be called zoom.mp4. When starting the program, you need to enter the necessary code in the taskbar and all actions will be performed automatically.
If you are a programmer who wants to create an exciting video using code, it is important to pay attention to many nuances and read the instructions in detail. Creating a video with code is a rather serious process that does not tolerate mistakes. Having made the slightest mistake or missing even one point in the step-by-step instructions, all your work will be defeated.
Even though programming is one of the most difficult areas to learn, creating a video from code can be a very simple task if you follow our tips. Check out the recommendations and start bringing your idea to life!
