Please note that VBR is also possible but prevents frame-exact Playback from first to last

frame. We strongly recommend CBR. Please also note that the Bit rate heavily depends on

the resolution of your video clip and on the content itself (e.g. lots of signal changes)

Using variable bit rate (VBR) causes loop problems, so please use constant bit rate (CBR)!

Please note that Framerates above 30 fps are extremely resource-consuming and will

increase the performance. Use these high framerates only for specific reason.

.GOP 12 is possible for simple Playback without jumping within the Frames (Indexing). The

more B- and P-Frames are used the higher the compression, the smaller the file size. I-

Frames only is also possible but increases the data rate.

Elementary Streams (ES) encoded with Main Concept Reference have the file extension.

mpv. Encoded files need to be renamed into .m2v, so that the VPU can read these files.

Program Stream = contains Video and Audio files, typical file extension: mpg
