Vendors we’ve used traditionally, such as Adobe and Black Magic, don’t support FFV1 natively – yet – though you can get a plug in for Premiere called DirectShow but I’ve not tried it. It’s an open format with a proven reputation like FFmpeg, and has alternative versions that can handle audio only files (mka), subtitles (mks) and stereoscopic video (mk3d). The principal interest for me is it allows embedding of capture log files when used with vrecord. Matroska is a really successful wrapper that can store an insanely high number of video, audio and subtitle streams as one file. To perform a fixity check of the file you just need to decode the video with FFmpeg again, and to display any FFV1 CRC mismatches in the terminal window use a command like the example below (credit and full instruction available at ffmprovisr).įfmpeg -report -i input_file.mkv -f null. The additional brilliance of the codec is its ability to store CRC32 checksums in every slice of a frame. For a more thorough explanation read the Wikipedia FFV1 page or take a look at FIAF’s recommended FFV1 reading list. VIAA Preservation Reformatting, by Jérôme Martinez and Dave RiceįFV1 is an amazing lossless video codec developed by the maker of FFmpeg that saves around 40-50% (sometimes up to 70%) file size without losing any valuable data.Indiana University Media Digitization and Preservation Initiative.This decision was informed in part by the BFI’s lead to use this codec and wrapper for their forthcoming mass video tape digitisation project, and research and light testing I had already carried out into FFmpeg/FFV1, informed by the following documents: In recent months we’ve made this move to open source tools following a decision to encode our digital video assets to FFV1 version 3 in a Matroska wrapper.
The Mac has a Black Magic Decklink Duo (1) card and software that includes Black Magic Media Express and Premiere Pro for capturing our Serial Digital Interface (SDI) feed. We’ve been capturing SD PAL video to v210 uncompressed MOV on a Mac Pro 5,1 since around 2011. I thought I’d document our leap into open source software here at the Media Archive for Central England (MACE).
