How to set up a cool encoder

Record Cool

The settings in the Encoder window will directly affect the video's quality, sound and bitrate.

Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size; If you want to make a video smaller, you can select compression mode, which is recorded at the specified output size, and can be configured with video quality and bitrate.

Frame rate (FPS): Set the frame rate, the greater the frame rate video smoother, but the file size and video CPU occupancy rate is greater.

Video quality and bitrate: (this option is only valid for compression mode) to set the video image and bitrate. The left side shows the size of the code rate under the current encoding parameters, the larger the code rate, the larger the resulting video file (like the first image).

Audio quality and rate: Set the audio quality and rate, where the "general" sampling rate is 22KHz, 32kbps, suitable for general quality requirements, "medium" sample rate of 44.1KHz, 64kbps, "better" sample rate of 44.1KHz, 128kbps, suitable for higher quality requirements. Similarly, the larger the audio code rate, the larger the file size.

Attention:

(1) The higher the video size and frame rate, the higher the CPU occupancy rate, select the appropriate parameters according to the machine performance.

(2) Video size, frame rate, picture quality and the greater the sound, the code rate will be larger, this can cause the file to be larger, or the network will transmit more data, so choose the encoding parameter that is appropriate for your network bandwidth, specifically, the sum of the audio and video rate should be less than the network bandwidth between you and the viewer, for example, if you and the viewer are in the 1M ADSL network, audio and video code rate and should be less than 1024kbps, otherwise the client will not be able to smoothly watch your live video.

Example:

Suitable for small files, low bandwidth encoding parameters: Screen size is 320x240,fps 5-10 frames, video quality of "medium", audio quality is "general".

Suitable for high definition, high bandwidth encoding parameters: The picture size is 640x480,fps 15 frames above, the video quality is "medium" or "good", the audio quality is "medium".

Suitable for local storage of HD Video Coding parameters: Screen size is "HD mode", FPS for 20 or 30 frames, audio quality is "better".
