Openmfd is an open-source printed circuit board by irudoy, from the irudoy/openmfd repository on GitHub, published under the MIT licence. It is a 2-layer board with 11 parts on 27 nets.
README
hardware/rgb-composite/README.mdThe reason why AD724 is not suitable for this application
From datasheet:
The AD724 can be used to convert the analog RGB output from a personal computer’s VGA card to the NTSC or PAL television standards. To accomplish this it is important to understand that the AD724 requires interlaced RGB video and clock rates that are consistent with those required by the television standards.
That's the case. STM32 LTDC can't output INTERLACED video signal.

Questions
What parts does the Openmfd use?
11 parts. 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.
Where can I download the Openmfd KiCad files?
From the irudoy/openmfd repository on GitHub, at the commit this page was made from: the board is hardware/openmfd/dummy/openmfd.kicad_pcb and its schematic hardware/dev-board/dac_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Openmfd design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
