What x264 CPU preset should I use?
What x264 CPU preset should I use?
Change your x264 preset The OBS default is veryfast, which for the majority of cases is the best balance between CPU usage and video quality. Faster presets will use less CPU at the cost of quality computations. Slower presets will use more computations for quality, but will use much more CPU.
Is x264 very fast good?
Ultra Fast is generally unusable, very blocky, NVENC Max Performance is a better choice if available. x264 FASTER has the highest overall score, followed by Medium, Slow and Very Fast….Forza conclusion (Fast gameplay):
Bitrate and highest VMAF | 6M | 4M |
---|---|---|
x264 VMAF (1080p/720p) | FASTER 82.95 / 86.16 | FASTER 76.11 / 79.42 |
What is the x264 encoder?
x264 is a free software library and application for encoding video streams into the H. 264/MPEG-4 AVC compression format, and is released under the terms of the GNU GPL.
Is x264 better than NVENC?
x264 provides quality preset settings from ultrafast to veryslow/placebo. On Turing-based NVIDIA GeForce GPUs (ex: RTX 20-Series and GTX 1660/Ti), NVENC produces an image quality comparable to the x264 medium preset. Older Pascal and Kepler GPUs produce an image comparable to x264 veryfast.
Is NVENC better than x264 for recording?
Turing NVENC has quality comparable to x264 Fast-Medium and negligible impact on FPS, unless you use a few of the new features introduced recently.
Which is better NVENC or x264?
NVENC or x264 x264 provides quality preset settings from ultrafast to veryslow/placebo. On Turing-based NVIDIA GeForce GPUs (ex: RTX 20-Series and GTX 1660/Ti), NVENC produces an image quality comparable to the x264 medium preset. Older Pascal and Kepler GPUs produce an image comparable to x264 veryfast.
What should my streaming bitrate be?
For 1080p video at 30 frames per second, the bitrate should be 3,500 to 5,000 kbps – same as for 720p video at 60 fps. The required upload speeds are the same too, between 4.4 Mbps and 6.2 Mbps. For 1080p video at 60 frames per second, the recommended bitrate is between 4500 and 6000 kbps.
Should I record GPU or CPU?
If you want to livestream to Twitch, Mixer, or YouTube Live, you’ve had two options when it comes to video encoding. You can set your CPU to do software encoding. You could alternatively select your Nvidia GPU to handle that task. Each of these have their benefits, but your best bet was to use your CPU.
Which is the best preset for x264 medium?
The variant with both aq0 and g480 still performs the best on VMAF on x264 Medium. The MS-SSIM scores work much the same as in the previous presets, with aq0 lowing the score significantly and g480 improving it just marginally.
Which is the Default Preset for x264 encoder?
The source video was nyan cat jazz, which I downloaded using youtube-dl , converted to YUV4MPEG2 using ffmpeg, then used x264 encoder to encode the raw video into a raw h.264 container. Comments and corrections are welcome. The default preset is medium, which is what the other presets are compared against. * – are differing values from medium.
What are the presets for x264 Apex Legends?
The VMAF scores for x264 presets are mixed. For the most part, Fast is the winner, followed by Medium, then Slow and finally VerySlow. The only exception, and where this differs from the 720p 60 fps Apex Legends test, is at very low bitrates, where Medium beats fast and VerySlow beats Slow.
What are the VMAF scores for x264 presets?
The VMAF scores for x264 presets are the exact opposite to what most people expect. Fast comes out as the winner, followed by Medium, then Slow and finally VerySlow. In other resolutions and games it may not be exactly like this. Different resolutions see different rankings between the presets. But that is a graph for another day. Stay tuned!
