JPEG XS is a light-weight compression that visually preserves the quality compared to an uncompressed stream, at a low cost, targeted at compression ratios of up to 10:1. With XS, it is for example possible to repurpose existing SDI cables to transport 4K60 over a single 3G-SDI (at 4:1), and even over a single HD-SDI (at 8:1).
OBS Studio is a free and open-source app for screencasting and live streaming. Written in C / C++ and built with Qt , OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via Real-Time Messaging Protocol (RTMP), HLS , SRT, RIST or WebRTC .
This page provides a comparison of notable screencasting software, used to record activities on the computer screen. This software is commonly used for desktop recording, gameplay recording and video editing.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
In ITU-T P.910, it is noted that methods such as DCR should be used for testing the fidelity of transmission, especially in high quality systems. ACR and ACR-HR are better suited for qualification tests and – due to giving absolute results – comparison of systems.
The High Throughput 4:4:4 10 profile allows for a bit depth of 8 bits to 10 bits per sample with support for 4:0:0, 4:2:0, 4:2:2, and 4:4:4 chroma sampling. The High Throughput 4:4:4 10 profile has an HbrFactor 6 times higher than most inter frame HEVC profiles allowing it to have a maximum bit rate 6 times higher than the Main 4:4:4 10 profile.
The end product of the offline non-linear editing process is a frame-accurate edit decision list (EDL) which can be taken, together with the source tapes, to an online quality tape or film editing suite. The EDL is then read into an edit controller and used to create a replica of the offline edit by playing portions of the source tapes back at ...
DASH is an adaptive bitrate streaming technology where a multimedia file is partitioned into one or more segments and delivered to a client using HTTP. [15] A media presentation description (MPD) describes segment information (timing, URL, media characteristics like video resolution and bit rates), and can be organized in different ways such as SegmentList, SegmentTemplate, SegmentBase and ...
