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):
