Compression
There are five options: H.264, H.264B, H.264H, H.265 and
MJPEG encode.
•
H.264: Main profile encode mode.
•
H.264B: base line profile encode mode.
•
H.264H: High profile encode mode.
•
H.265: Main profile encode mode.
•
MJPEG: In this encode mode, the video needs larger bit
stream to guarantee the video definition. You can use the
max bit stream value in the recommend bit to get the better
video output effect.
Image capture size There are multiple resolutions. You can select from the dropdown
list.
•
For each resolution, the recommended bit stream value is
different.
Frame rate(FPS)
NTSC: 1-60fps, PAL: 1-50fps
The frame rate may vary due to different resolutions.
