Post as a guest Name. Email Required, but never shown. The Overflow Blog. Each frame is divided into pixel blocks of which are called macroblocks.
And intra prediction is to predict the luminance and color components of blocks by referring to the surrounding and previously-codec pixels within the current image. The intra prediction methods of H. It supports 9 directional prediction modes and 4 macroblock partitions 16x16, 16x8, 8x16, and 8x8. When processing images without complicated color and luminance changes, it'll divide macroblocks into sub-macroblocks of 8x8, 4x8, 8x4, and 4x4.
Although inter and intro prediction removes large amounts of redundant data, the residual data can be further modified. Then we come to the next step, transformation. It aims at converting the motion compensated residual data into another domain. The transform used in this video coding standard is computationally flexible, which requires low memory and a low number of arithmetic operations.
It a revisable calculation method and apply the main condition of the transformation process. The data after transforming is a set of coefficients. Quantization is to reduce the range of transformation coefficients and mapping them to specific ranges because human beings are more sensitive to lower frequency signals than higher ones. The goal of quantization is to compress high-frequency signals for better visual results.
Since H. Its adaptive in-loop deblocking filter comes to smooth the edges between pixel blocks. This filter is adaptive on three levels — slice level, block edge level, and sample level.
Entropy coding is a lossless data compression scheme to convert image data into bitstreams that can be stored and transmitted. The entropy coding algorithm used in H. It is one of the crucial elements that make H. To play an H. The video decoder receives the bitstream, then decodes and extracts info from elements above, finally reconstructs a sequence of images.
MPEG-2 H. It was released in and surely it is not as efficient as its next generation codec, H. While H. It is primarily known as a low-bit-rate video codec for video conferencing. Before H. Later on, H. Because H. Most new videoconferencing products now support H. Windows Media 9 accurately called Windows Media Encoder 9 is a free media encoder created by Microsoft.
It was developed to convert audio, video, and computer screen images to Windows Media formats for live and on-demand distribution. Windows Media 9 is developed by a single company for narrow uses, while H. And video quality tests from Apple shows that H. Pixlet is a video codec developed by Apple in at the request of animation company Pixar and only available on Mac OS X Pixlet and H.
The former was is focused on video editing instead of distribution. Without interframe compression, it plays a video frame by frame so that artists can scrutinize every detail of the sequence.
Thus it requires high-end hardware for the professional playback process. Pixlet may require about 40 Mbps for x content, H. This efficiency in H. Ten years after the birth of H. Compared to H. Some newer devices are starting to ship with a built-in hardware decoder to play H. As of , H. But the enhanced video quality and reduced bandwidth come at a cost. At present, H. Read the comprehensive comparison: H. But before , enabling real-time video natively on the web was not this easy.
In , Cisco released open-source H. It provides the source code and a binary module that can be downloaded from the Internet for free. And H. For all I know it could be a simple mistake in the set-up of the program, but uninstalling and reinstalling has never helped the issue in the past.
I can say that it has happened to me, in the last 2 years, around ttimes now and between all of them, the biggest things between them all that are similar is more expressions than usual and it happens most frequently on complex animations. We're sorry for the delay in response. We'll make sure this issue gets addressed on priority and hopefully this will make this experience better. I'd like to straight up apologise for my outburst but I have been seeking help with this for almost 2 years now and nobody seems to bring anything that makes any sense to the table.
I've when through hundreds of forums and on at least 30 different occasions, spent hours on live chat being asked ridiculous questions like "are you windows or mac" straight after claiming it gives me the Blue Screen lol. The issue has only ever happened to me with H. I will set up a render that I know to cause me issues and will try another format and report back. I appreciate this help a lot. Blue Screen of Death almost always happens due to driver issues.
Adobe Software uses those drivers, but sometimes the drivers aren't perfect even if it's the latest. If one does not work, I recommend trying a different kind. Can you disable GPU acceleration is see if the crash still happens? Maybe try to take out a couple of sticks to see if that fixes anything? Unlikely to be the problem for a new machine, but since your RAM utilization is so high, it would be good to test. About your GPU utilizatiuon: you have an awesome Video Card, but GPU Acceleration is only used for certain effects, deintarlacing, scaling, and some other things that will not push your utilizatiuon too high unless you are working with 8k VR for example.
If you are able to send me a reduced project that reproduces the issue for you, I'll be happy to try it on a number of different machine configurations.
If not, try to provide more details about the project. Does it usually crash around the same time? Are you using any 3rd party plugins in your project? Any info helps. I am not sure if you have already tried this or if your issue was resolved.
