Question/Problem
The video capture card VM4-2-C8 provided by the company VITEC currently supports the video recording formats MPEG1, MPEG2 and MPEG4.
However if this capture device is plugged into a mainboard that operates with a CPU INTEL Core i7 processor (13700K, latest generation), capturing MPEG4 video clips is no longer possible. What is the exact reason for that?
Answer/Solution
INTEL CPUs of the latest generation (e.g. Intel Core i1-13700K, Chipset Z790) have got the following default specification:
16 physical cores
8 performance cores (hyperthreading included)
8 efficiency cores
24 logical cores (8(P)+8(HT)+8(E)).
Single cores can be deactivated in the BIOS, so that the CPU will work with the following adjusted specifications
15 physical cores
23 logical cores
Using this new configuration the VITEC board VM4-2-C8 will already be able to record MPEG4 clips without any problems
Recording MPEG4 clips with the VITEC board VM4-2-C8 requires a specific maximum of CPU cores which must not be exceeded.
Deactivation of more than 1 physical and more than 1 logical core may be necessary in the future, as the number of cores in later CPU generations will to rather increase.
As an alternative the video capture board VM4-C9 connected with an additional bracket (index 17990) can be plugged into a mainboard with a CPU INTEL Core i7 (13700K, latest generation) instead. Users thus will be able to record video clips in HD-and SD-quality:
The addtional bracket can be connected to the latest series of the VITEC board VM4-C9 via 2 specific ports (highlighted in green):
