Why use h 264 codec

Simply stated, the primary reason that H. That said, there are several submarkets where other codecs are making serious inroads. When gauging codec performance, you consider two aspects: 1 encoding complexity or speed, and 2 encoding quality. That is, the better the encoding quality, the longer it takes to encode. This translates to higher encoding and transcoding costs.

Since no codec can completely replace H. To explain table 2, encoding complexity is the encoding time as compared to H. So, for VP9 , encoding should take between 2—15 times longer than H. Encoding quality describes the bitrate reduction the codec can achieve while delivering the same quality as H. Of course, better encoding quality offered by VP9, HEVC , and AV1 decreases bandwidth costs for delivery to compatible players, which can in turn offset the additional encoding and storage costs.

Still, most companies excluding the top tier of streaming broadcasters tend to adopt new codecs only when they enable entry into new markets, not as a cost-saving measure.

We see in table 3 that codecs also vary in suitability for different functions. Understandably, H. On the other hand, if you compare H. For this reason, though H. Though there have been several H. Like all codecs, H. There are, however, three configuration options that all producers should understand. Compared to H. To find out how you can easily implement a H.

Not now View my last basket. The Black Box website uses cookies. If so what would be a good bitrate to transcode at, is there a rule of thumb based on the bitrate of original footage from h. HEVC has not really caught on and new codecs designed to replace it are already shipping and gaining market presence. We are a few years away from figuring out what the true successor to H. The specific compression setting bit rate varies by frame size, frame rate, bit depth, and the amount of movement between frames.

When I uploaded it on Facebook, the video was grainy, blurry and somewhat pixelated. What kind of settings or codec do I use? This forces Facebook to rescale your video. I would, instead, compress your video into x , using the YouTube presets in your compression software. When you recompress, set it to 60 fps. If you are trying to display slow motion, create the slow motion in your video editing software, then, export a 60 fps master file.

This means that Facebook needs to create an 8-bit version of your video for distribution. This is also where you lose quality control. Instead, create an 8-bit H. All true. However, simply because you can record all that image data in the camera, does not mean you can distribute it.

Look at all the television programs that were shot on film, yet displayed on standard-definition TV sets. Your email address will not be published. Access over 1, on-demand video editing courses.

HEVC first divides the picture into different CTU sizes , and the biggest pixel block size typically increases the coding efficiency.

This makes H. When you examine the technology behind these two codecs, you can easily conclude which one wins. The biggest difference here is that H. This significantly lowers the required bandwidth. Then, another perk of H. This enables H.

That is quite helpful for your viewers in that their devices will require less bandwidth and processing power to decompress all information and watch a stream. Everything we mentioned above points to the fact that, when it comes to this H.

H comparison, H. In conclusion, if you want to deliver the best quality video in the smallest possible format, then you should go with H.
