JVC VN-H237U manual 31

C Multi-Encode2			The following can be set for Encoder No.1 and Encoder No.2.
			JPEG(1280 x 960) + MPEG4 (640 x 480)
			JPEG(1280 x 960) + MPEG4 (320 x 240)
			JPEG(640 x 480) + MPEG4 (640 x 480)
			JPEG(320 x 240) + MPEG4 (320 x 240)
			The frame rate can be set to 15 fps or lower.
	Encoder	Encoding	Displays the “JPEG” encoding selected for Multi-Encode2.
	No.1	Display
		Framesize	Displays the frame size selected for Multi-Encode2.
		Framerate	Specify the frame rate for Multi-Encode2.
			[Set values: 15 fps, 10 fps, 7.5 fps, 5 fps, 3 fps, 2 fps, 1 fps]
		Picture	Select the JPEG picture quality (rate control mode) and picture quality level.
		Quality	When "AFS" is selected, encoding is performed such that the target file
			size is the average size of multiple JPEG images.
			When "VFS" is selected, the quantization table during JPEG encoding
			will be maintained and the file size will increase or decrease according to
			the input signals. When recording JPEG data to a recorder with a limited
			storage capacity, note that the maximum recording time may vary as the
			file size fluctuates under this setting.
			[Set values: AFS, VFS]
			Picture quality level
			[Set values: Level 1 to Level 3 to Level 7]

Memo:

●The chart below shows file sizes for each combination of frame size and picture quality level.

●Select between level 1 and level 7. The picture quality increases when the level value is small. However, the file size increases (see the table below).
