Video
The Video window allows you to configure all video streams (the no. of stream available can be
different for different models). You can configure the following:
1. Codec: video compression codec in H.264 or MJPEG. Note that MPEG-4 is not supported for
Liveview.
2. Frame size: video resolution. Note that due to the limited CPU resources, you may not be
able to change the resolution to a very high value, e.g., 5MP in the 1920x1920 resolution.
3. Maximum frame rate: the highest frame rate.
4. Intra frame period: How often an I-frame will be inserted into the video stream.
5. Video quality: You may either select Constant bit rate or Fixed Quality as the defining rules for
video transmission:
Constant bit rate
Fixed Quality
When done with the configuration, click the Apply button.
