Also, set the x264 CPU Preset to "Ultrafast". Encoding settings I think most of these values are set by default, the important part here to achieve lossless quality: qp=0, do not use crf=0, it's insanely high bitrate too, but not 100% lossless. Video Source Set the preferred resolution and framerate here. ![]() I used a WD Green 4TB drive with 5400RPM, so a Raid should not be necessary. Set the file location, preferrably an SSD, but a non-crap HDD should do fine too. File Saving Set the mode to record to a file. For Audio, I'm not sure if you can add FLAC to OBS as a plugin or so, you should probably (or already do) use something like AudaCity for better audio recording, I'm not an expert yet for that. This is not the bitrate the video will be encoded with, but a maximum that is allowed for the encoder (x264). It's really awesome, the best capturing software available IMO while also being free.Īfter installation, you need to make the following settings Video Bitrates Set these bitrates to something insane, like 1Gbit as seen in the screenshot, both values are in Kbit/s. ![]() ![]() In this quick guide, I'll show you how you can record your game at full resolution (1080p+), high framerates (60fps) at sane filesizes while having a low CPU load to not interfere with your game, all while being lossless! (8-bit YUV 4:2:0, 10-bit should be possible to by swapping out the x264.exe I guess, but that might kill the FPS drastically)Īll you need is: Open Broadcaster Software aka OBS, this is a free, open source recording software that uses the x264 video encoder (H264/AVC standard) and is mainly intended for streaming (such as Twitch), but can also be used to write files locally to the hard drive. Hi, I've seen the question of how to properly record game footage for trailers and other promotional or private purposes pop up here from time to time, often left with short answers as to what software to use (Fraps, DXTory, Bandicam, Camtasia etc), but not the full process.
