Multichannel modular analog PAL video mixer based on the SYNKIE project
Vm002-resync is an open-source printed circuit board by mirdej, from the mirdej/vmix repository on GitHub. It is a 2-layer board of 86.4 × 33 mm with 43 parts on 29 nets, routed with 325 tracks and 10 vias.
It is built around the LMH6643MM and BAT54S. Its parts include 15 resistors, 10 capacitors, 9 connectors, 4 ICs and 2 transistors.

Multichannel modular analog PAL video mixer based on the SYNKIE project
The Anymix21 is a 12 channel analog video mixer based on the paradigm of classic audio mixing desks.
Each channel is a complete SYNKIE by itself, sort of. It can handle anything from DC to around 10Mhz, this means you can mix CV signals with audio with PAL composite video signals. Contrary to an audio mixer, inputs are DC coupled, with 0v being black and 0.7V white level. Negative levels are permitted but will be clipped at the final output stage.
Each channel has a built-in equaliser, switchable edges (bandpass), comparator and inverter effects, and a scale-bias module for adjusting brightness and contrast. The signal can then be routed to 3 main output mix busses and an auxiliary output.
Apart from the equalizer, the effects and mix levels are digitally controlled analog, so parameters can be recorded, automated, or controlled externally through MIDI. The desk can be synchronized to a MIDI clock (which is then quantized to the vertical blanking interval derived from the genlock input).

Still under construction, the first 6 channels have passed their endurance test running daily for weeks at the exhibiton “H.o.Me. – Heim für obsolete Medien” at Kunsthaus Langenthal.

It measures 86.4 × 33 mm and has 2 copper layers, 1.6 mm thick.
43 parts, built around the LMH6643MM and BAT54S. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the mirdej/vmix repository on GitHub, at the commit this page was made from: the board is old/vm002-resync/vm002-resync.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask mirdej before reusing the design.
