Video Encoding Is The Process in Which Raw Video Files

Video Encoding is the process in which raw video files are compressed into smaller sizes and converted into divergent file formats using Codecs. This is done for the purpose of easing broadcasting and streaming video files over various platforms. Process in Which Raw Video Files If these raw files won’t be compressed then it would be difficult to transmit such huge files over the internet, as the amount of bandwidth available is not sufficient to deliver such huge files. Moreover many users use mobile internet, which has much less bandwidth than that of broadband users. In order to serve everyone’s demand, video encoding has proved to be a boon for the internet users.

What are codecs Process in Which Raw Video Files?

Codec stands for coder-decoder and refers to the algorithm used to digitally encode a video. It has a dual functionality i.e. a codec is the algorithm that compresses raw video before decompressing it for streaming or file transmission. It ensures that the file size is reduced to a certain size without diminishing the quality of the video and ensures it is feasible to stream.

How Video Encoding is done

Encoding is another term for compression, which makes it easier to transmit a video file over a distance or to disseminate to multiple endpoints or nodes. So how does the compression happen? Video compression codecs reduce the size of a video file by simply following a set of programme operations that allow a computer system performing video encoding to compress video data into smaller file sizes without a significant or noticeable loss in quality.

So which one among H.264 and H,265 is the better one?

H.264, also referred to as AVC (advanced video coding) The motion picture experts group, or MPEG, defined H.264 in part 10 of its MPEG-4 standard. It is a well-known video compression standard for high-definition video. It is the newer video compression standard, and because it is newer, it is also the better video compression standard. First published in 2013, H.265 has yet to catch up to H.264 in terms of popularity, but it is on its way. According to the video developers report of 2021, H.265 is the second most widely used video coding standard after H.264.

Basic comparison between H.264 and H.265 codec
H.264 is a block-oriented compression standard that compresses video frames using a block-oriented motion-compensated based video compression technique. This allows H.264 to reduce video file size without sacrificing video quality. There are various video formats that implement H.264 compression standards, but the dot mov and dot mp4 formats are two of the most common.

H.265 on the other hand compresses data utilizing coding 3 units, or CTUs. A macro block can range from 4×4 to 16×16 block sizes, whereas CTUs can process up to 64 by 64 blocks, allowing them to compress data more efficiently. This means that h.265 can preserve more information in a movie after compression than H.264.

Comparison on the basis of bandwidth requirement

The key difference is that HEVC allows for even smaller file sizes, which reduces the amount of bandwidth necessary for live streaming and video recordings. In the real world, this means that when you’re recording or streaming a video, you can stream at a much higher quality while using the same, if not smaller, file sizes than the H.264 file format. In such, H.265 requires less bitrate to store the same amount of information as H.264.

The larger the video size, the higher the bitrate, thus this is just a real-world example to provide you a comparison. H.265 has much better motion compression and spatial prediction than H.264. That means even though a video has a lot of background movements H.265 can still compress and run it at a lower bit rate.

Should you go for H.264 or H.265 ?

After going through this comparison, one would go for H.265 over H.264. But the question arises, Why is H.264 still the most preferred codec? This is because H.265 requires a powerful gear with very high computing power to run it. Which is not available in many devices around the world. But day by day more advanced devices are emerging with higher computing power, and with it H.265 preference is increasing. Nowadays online operators like Muvi’s in-built encoding converts your videos into streamable digital format and compresses them automatically.
