AXIS M30 Network Camera SeriesLearn moreStreaming and storageVideo compression formatsDecide which compression method to use based on your viewing requirements, and on the properties of your network. Theavailable options are:Motion JPEGNoteTo ensure support for the Opus audio codec, the Motion JPEG stream is always sent over RTP.Motion JPEG, or MJPEG, is a digital video sequence that is made up of a series of individual JPEG images. These images are thendisplayed and updated at a rate sufficient to create a stream that shows constantly updated motion. For the viewer to perceive motionvideo the rate must be at least 16 image frames per second. Full motion video is perceived at 30 (NTSC) or 25 (PAL) frames per second.The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to every imagecontained in the stream.H.264 or MPEG-4 Part 10/AVCNoteH.264 is a licensed technology. The Axis product includes one H.264 viewing client license. To install additional unlicensedcopies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.H.264 can, without compromising image quality, reduce the size of a digital video file by more than 80% compared to the MotionJPEG format and by as much as 50% compared to the MPEG-4 standard. This means that less network bandwidth and storage spaceare required for a video file. Or seen another way, higher video quality can be achieved for a given bitrate.H.265 or MPEG-H Part 2/HEVCNoteH.265 is licensed technology. The Axis product includes one H.265 viewing client license. To install additional unlicensedcopies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.How do Image, Stream, and Stream profile settings relate to each other?The Image tab contains camera settings that affect all video streams from the product. If you change something in this tab, itimmediately affects all video streams and recordings.The Stream tab contains settings for video streams. You get these settings if you request a video stream from the product and don’tspecify for example resolution, or frame rate. When you change the settings in the Stream tab, it doesn’t affect ongoing streams, butit will take effect when you start a new stream.The Stream profiles settings override the settings from the Stream tab. If you request a stream with a specific stream profile, thestream contains the settings of that profile. If you request a stream without specifying a stream profile, or request a stream profilethat doesn't exist in the product, the stream contains the settings from the Stream tab.Bitrate controlWith bitrate control, you can manage the bandwidth consumption of your video stream.Variable bitrate (VBR)With variable bitrate, the bandwidth consumption varies based on the level of activity in the scene. The more activity in the scene,the more bandwidth you need. You are guaranteed constant image quality but it requires storage margins.18
