I’ve been struggling to work with Python for over a year since discovering … Continue reading DIY Python microservices in audiovisual preservation workflows
I thought I'd document our leap into open source software here at the Media Archive for Central England (MACE). We've been capturing SD PAL video to v210 uncompressed MOV on a Mac Pro 5,1 since around 2011. The Mac has a Black Magic Decklink Duo (1) card and software that includes Black Magic Media Express … Continue reading Open Source FFV1 video capture workflow for MacOS
