Why We Require Video Delivery Format For Web

Why We Require Video Delivery Format For Web 2

Video has come a long way since magnetic tapes were involved and it’s time to ensure that you’re using the best format for displaying video content on your website. Including videos helps make your content easier to connect with the people. If you’d like to have greater control over your video then the HTML5 video is your solution. the HTML5 only works with a few file formats (currently) – MP4, OGV, WebM, and WebVTT – and each format has at least one strong reason to employ it.

One of the biggest sources of confusion about the video is not realizing that the file format is completely different from the video format. So we are always dealing with two formats, not one. Sometimes files formats are called container formats because they are the containers for the actual video. In fact, the video format is the flavor of compression that is used in the video.

# MP4 It is the most widely used media format for the digital devices and many platforms support MP4 which makes it universal video format around the world. The MP4 can also store video files, audio files, text, and still images and they can retain high video quality while maintaining relatively small file sizes.

# OGVOGG was originally designed as an audio compression package in the early ‘90s but matured over the next two decades. What started as a workaround led OGG to give birth to OGV, a digital multimedia file format redesigned for efficient streaming over the internet. The format does not (currently) work with any version of Internet Explorer nor Safari.

# WebM – Introduced in 2010, WebM is a completely open-source video format which delivers the highest quality video in real-time, adjusting file weight depending on connection and processing power. It is designed and developed with widespread web use and sharing in mind and has its compatibility with Chrome on Android devices.

# WebVTT – WebVTT was developed by W3C (the World Wide Web Consortium) in 2010. It is the most compatible video tag format currently available. The cross-operating system and cross-browser support WebVTT and make it the logical choice for videos on any website. 

How Progressive Download Works?

Progressive download is a method which is used to stream media from the web server to the client such as a video player on a laptop or mobile phone. Without using progressive download a client has to download the entire media file before video playback can start. Media files are typically large, so users must wait a significant time before they can watch the video, resulting in disappointing user experience. With progressive download, only a small part of the video file has to be downloaded before playback begins. The progressive download is video delivered by a regular HTTP web server rather than a streaming server. In most instances, the video delivered using this technique is stored on the viewer’s hard drive as it is received and then it is played from the hard drive. 

How RTMP STREAMING Works?

Real-Time Messaging Protocol was basically a protocol developed by Macromedia (owned by Adobe). It gained its popularity for streaming audio, video and data over the Internet between a flash player and a server. There is a direct pointer from the media server to flash player, and only data corresponding to that pointer is held by the flash player. A video player is used for sending the streams file corresponding to its screen size and internet connection speed. In RTMP streaming process it is ensured that if a viewer is initially viewing a high-quality stream at high bandwidth and after some time if the internet speed drops then the video player will immediately switch to a lower resolution stream. In this process, there is no storage of any kind of data on the computer. 

How HTTP STREAMING Works?

HTTP live streaming is the streaming which can host the streamable content without a streaming server because of the HTML5 and hypertext transfer protocol. HTTP Streaming is a push style type data transfer method that allows a web server to continuously the send data to a client over a single HTTP connection that remains open indefinitely. With HTTP Streaming, the server is configured to hold on to a specific request from a client and keeps the response open so that it can pass data through it. When updates pertaining to the request are available along server-side, the server sends the response through the request-response channel and only closes the connection when explicitly told to do so.

What is HLS Encryption? Is HLS Encryption effectively secure against piracy?

HLS Encryption

HLS Streaming ( HTTP Live Streaming) is a streaming protocol which is used for the video content across the computers and mobile devices. HLS encryption refers to video streaming using HLS protocol where the video files are encrypted by using  AES-128 algorithms. The key exchange takes place through the secure HTTPS protocol and also allow for the usage of initialization vectors to optimize the protection.

You can protect your videos with 128bit AES (Advanced Encryption Standard) HLS encryption to protect your videos from unauthorize download attempts with tools and video downloader such as Internet Download Manager. Making it by far one of the most secure platforms to stream and secure your videos and it makes sure that your videos are secured using the latest protection technologies.

How To Protect Videos Using AES – 128?

The HLS mentions only one aspect of key retrieval which is by using the URL from which the key can be loaded should be a part of the manifest file. Most often, we see a number of different approaches for protecting the decryption key:-

 1. By Protecting the manifest:-

This is the way through which we can hide the URL to the decryption key. It does not provide more strong security as the URL might leak or could be intercepted on the network.

2. Using Authentic Cookies:- 

Authentic cookies can be sent by the video player with the request key. This allows the server key to check which user is requesting the key. If the user is not allowed to access the stream, the key will not return back and the user which have proper authentication will receive the decryption key.

3. Using Signed URL:-

Signed URLs can be used for providing unique representation to each user. A user-specific representation will then contain a link for the decryption key which will contain an authentication token. The server can then check the authentication token and determine whether the key can be accessed or not.

Is AES-128 protection Safe?

The first question while dealing with videos protection is “How safe is this protection?”  AES is a symmetric encryption algorithm which is designed to be efficient in both hardware and software. This algorithm is adopted as the standard encryption algorithm by the U.S. government for encrypting sensitive data. The usage of AES encryption has recently become the part of common encryption and it might be safe to say this level of AES encryption will not able to replace soon.

Which is More Important? FPS or Video Resolution.

Which is More Important? FPS or Video Resolution. 5

What’s supposed to be a nice design feature that adds to the overall impression of a website can turn into a nuisance for visitors if they have to wait for all elements to load and display correctly. one way for optimizing videos for web design is to reduce the video’s file size, which will help to drastically improve page load times and playback performance. However, as each of these factors Frame rate and Video resolution affect the size of the video. Having a high Frame rate and a good Video resolution would increase the size of the video, it may be in the best interest of a web designer to go for both frame rate and resolution so it becomes confusing to understand which one is more important.

Videos are main aspect, used in 90% of sites mainly 34% promotional videos, 31% demonstration videos, 31% demonstration videos, 26 % entertainment videos, 22% news videos, 4% User Generated Content (UGC), 3 Other. It should be optimized with mobile phones as 63% of web surfing is done on Mobiles.[1]…

Why Does Frame Rate Matters?

The term FPS stands for “frames per second” and is also called “frame rate”, referring to both recording and playback speed when talking about video. In regards to shooting, the frames per second measurement are how many frames or images are taken in one second. Frame Rate is the frequency at which the display refreshes. Frame rate options are 24 or 30, 60, 120 and 240. 24 or 30 is determined by the “base frame rate”. 

While it won’t make your image look sharper, it only improves usability and makes animations and effects appear nicer and better on the screen.

Why Does Video Resolution Matters?

Video resolution in a display device refers to the number of distinct pixels that could be displayed in each dimension. It is usually quoted as width× height. The video resolutions you see like 360p, 480p, 720p, or 1080p represent the number of horizontal lines a video have from top to bottom. A 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide. In other words, a 480p video has a resolution of 852×480 pixels.

For comparison, a 720p HD video has 720 lines that are each 1,280 pixels wide, this means that it is more than twice as sharp as the same video at 480p and can be viewed on a much larger screen.

Conclusion – 

Higher quality video is always the most desirable. As a web designer if I have to go with these two then I will shake hand with the video resolution because while designing a web the video size matters a lot so it’s better to choose a video of higher resolution rather than FPS. A video of lower size and higher resolution will consume less time to load and will provide a great experience to the users.
