![]() Take full control with VST plugin support Intuitive audio mixer with per-source filters such as noise gate, noise suppression, and gain. ![]() Set up an unlimited number of scenes you can switch between seamlessly via custom transitions.Create scenes made up of multiple sources including window captures, images, text, browser windows, webcams, capture cards and more High performance real time video/audio capturing and mixing.Record videos to save to your hard drive and share with friends.Livestream video to sites like Twitch, YouTube, Facebook Live, and many more, including your own custom servers.Stream your video productions on sites like Twitch, YouTube, or Facebook live, or record your videos locally to share. Although it was said to be incompatible with trellis, deadzone is still active when using with trellis=1.OBS Studio is a free and open source program for livestreaming and video recording.Ĭreate scenes with multiple types of video sources, including your computer display, video games, webcams, video files, and more. Very fine detail is both hard to see and expensive to encode, dropping this detail without attempting to preserve it stops wasting bits on such a low-return section of the video. The deadzone value sets the level of fine detail that x264 will arbitrarily drop without attempting to preserve. trellis: performs trellis quantization to increase efficiency.The result is a bias towards a detailed and/or grainy output image, a bit like xvid except that its actual detail rather than ugly blocking. Therefore, we would rather see a somewhat distorted but still detailed block than a non-distorted but completely blurred block. the human eye doesn't just want the image to look similar to the original, it wants the image to have similar complexity. psy-rd: Psychovisually optimized rate-distortion optimization.animation, grain and stillimage use psy-rd 1st/2nd value which requires subme>=6/trellis>=1. This option disables this, and forces x264 to generate its own. force-cfr: if using ffms2 or lavf demuxers, timecodes are copied from the input file, provided the output file is not raw.sync-lookahead=0 disables threaded lookahead, which allows lower latency at the cost of reduced performance, default=bframes+1. sync-lookahead: sets the number of frames to be used as a buffer for threaded lookahead.ultrafast value uses no-deblock, which completely disables the loop filter. It is very efficient in terms of encoding time vs. no-deblock: deblock controls the loop filter (aka inloop deblocker), which is part of the H.264 standard.Using a value less than 2 will enable a faster, and lower quality lookahead mode. ![]() subme: set the subpixel estimation complexity.Without AQ, x264 tends to underallocate bits to less-detailed sections. This threading method produces lower quality results than the default method both compression and efficiency-wise, but adds no encoding latency. sliced-threads: enables slice-based threading.weightp: enables use of explicit weighted prediction to improve compression in P-frames.no-weightb: H.264 allows you to 'weight' references in B-frames, which allows you to change how much each reference affects the predicted picture.Setting scenecut to 0 is equivalent to setting no-scenecut. scenecut: sets the threshold for I/IDR frame placement.These blocks can be further split up into smaller partitions, which is what this option controls. partitions: H.264 video is split up into 16x16 macroblocks during compression.This setting controls how x264 decides between placing a P- or B-frame. b-adapt: set the adaptive B-frame placement decision algorithm. ![]() This can lead to significantly better efficiency in terms of compression ratio. B-frames are similar to P-frames, except they can use motion prediction from future frames as well.
