Most IP cameras today support multi-stream. The compression rate, image quality, complexity and compatibility are all between JPEG and H.264. MPEG4 generally works the same way as H.264 and has the same pros and cons. Mediocre quality and compression rate (between JPEG and H.264).Good compatibility (between JPEG and H.264).The right image shows artifacts which are absent in left one. The two images are 2 consecutive frames of an H.264 video. This sometimes leads to problems causing corrupted images or even data that cannot be decompressed at all. Different venders and parties do not always understand H.264 standard the same. Compatibility - H.264 is sophisticated and 'sophisticated' usually means complicated.To display multiple live H.264 videos, NVR systems must use very high-end and expensive PCs. Computing complexity - It takes considerably higher CPU time to decompress H.264.This makes motion detection and object tracking very unstable. But in in JPEG they are more consistent and in H.264 the artifacts usually grow and disappear suddenly and grow repeatedly. Artifacts - Artifacts (image features created by compression and are not visible in real scenes) appear in all compressed video, both JPEG and H.264.Inconsistent image quality - When a snapshot is taken it could be almost as good as JPEG or it could be very low quality.

But this method causes few problems that haunt IP surveillance for years: The compression rate is significantly higher than JPEG. It analyzes foreground (changing parts) and background (static parts) in video and avoid redundant information. H.264 is a more advanced technology for compressing video. Compress/decompress complexity (heavy CPU loading for both camera and NVR).
#H.264 video codec series
Motion JPEG, MJPEG, and MJPG all refer to the same thing they are basically a series of JPEG images. The frame rate is usually low and data rate is high. The problem with JPEG is that it's originally designed for static images. It's less prone to broken images and has the best image quality. JPEG is widely used in consumer products and had been developed earlier. There's no single 'best codec' in the world. Most cameras support more than one codec as each codec has its pros and cons. There are 3 common codecs widely used today JPEG, MPEG4, and H.264. The method used to compress video are called 'codecs'. Most, if not all, IP cameras stream video compressed. You obtain results immediately due to the fast and simple access to video configuration, while keeping file size reasonably small.Introduction to Video Codecs: JPEG, MPEG4, and H.264 Overview
#H.264 video codec software
In conclusion, DivX H.264 Decoder is a useful, advanced piece of software that extracts the best out of your video contents using the H.264 codec. You can select from the “Original Trust Container” and “Bitstream” and you can switch between PAL and NTSC video formats.

You don’t need to worry about ruining the quality of your videos, since you can always go back to their initial state, by using the “Default” button and the slider buttons can be translated to both positive and negative values if you have altered the original too much.Īnother advanced option of the DivX H.264 Decoder is choosing pixel aspect ratio. Furthermore, you have the possibility to adjust the video material (smoothing sharpness, deinterlacing, correcting brightness, contrast and saturation). Out of its many features, DivX H.264 Decoder enables its users to toggle multithreading, or to obtain higher performance when playing a video on a multi-core computer.

The installation is fast and simple and the application uses very little of the system’s resources.

#H.264 video codec install
The codec is easy to use and once you install it, you will get a configuration window which enables you to use all its functions. This format is suitable for any platform, from hand-held to high definition. The H.264 standard itself is superior to other commonly used formats. The main advantage of this codec is the use of an advanced compression method which allows you to obtain high-quality videos while keeping the bit rate low. A DirectShow filter aimed at decoding H.264/AVC video files it performs comparably to CoreAVC.
