Does NVENC or x264 look better?
But there is a slight trade-off in quality, and the reality is that x264 looks better than both NVENC and AMF when given enough power to do its job. When selecting a x264 you can then adjust the CPU Usage Preset from ultrafast all the way down to slow and placebo.
Should I stream with NVENC new or x264?
x264 uses your CPU to encode video. On faster presets, the CPU spends less time which is less resource intensive, but produces a lower quality image. NVENC is an NVIDIA encoder that uses a dedicated encoder within your GPU to handle all encoding, allowing you to play and stream without compromising game performance.
Is NVENC H264?
If you use GTX 600 series or higher graphics cards, you will be able to use the Nvidia NVENC H264 encoder which allows you to record the target with high speed, high compression ratio, and excellent quality. …
Should I use NVENC new or old?
There is no difference between the NVENC old and new encoder qualitatively, regardless of NVENC generation. It is purely a functional efficiency improvement. It uses the same encoder stack. It will output the same video on old or new on a given card, unless the user has made other changes to the settings.
What should the QP be for H264 NVENC?
This is only usefull for recording, as the bitrate fluctuates upredictably. Instead of a bitrate define a QP for nvenc. Start your tests with 19 or 21 for achival and much higher values for small files. For x264 define CRF and start with 16 or 19 for HQ archival and 20 to 23 for small client-files.
Which is the best preset for H264 NVENC adjustment?
Spatial and temporal AQ rearange bits inside the frame for better percieved quality (psyo-visual tuning). I use 3 bframes that can be used as a reference (b_ref_mode 2). In contrast: OBS has a preset for highquality (a bit less than slow, but it doesn’t really matter), lookahead and psyo-visual tuning.
Can you use H264 _ NVENC on a vMix?
Upon experimenting with h264_nvenc on a RTX2080super with vMix and OBS for high-quality streaming I ended up with much better quality streams and records of OBS. CPU-driven x264 is not my primary goal but it needs some adjustmens too, but first to Hardware Encoder “NVENC”.
What kind of encoder is Nvidia NVENC H.264?
Encoder: NVIDIA NVENC H.264 (new). Rate Control: We recommend CQP, although VBR will also produce good results. CQ Level (CQ): 15 (you can decrease the number to get higher quality). Bitrate and Max Bitrate (VBR): 40,000 Bitrate; 60,000 Max bitrate.
