Using Open Source Tools to Capture Closed Captions and Timecode | The Signal
Vrecord is open source video capture software used by video preservation labs across the nation, with one of its most notable features being the ability to natively capture and encode FFV1 Matroska files. Until recently, the NAVCC Video Lab has not been able to capture all tapes into FFV1 Matroska due to some of vrecord’s limitations. This blog post describes a number of FADGI funded updates to vrecord which expanded the tool’s ability to digitize various video tape formats from the Library of Congress' collection.
