FFV1, which stands for "FF video codec 1", is a lossless intra-frame video codec. It can use either variable length coding or arithmetic coding for entropy coding. The encoder and decoder are part of the free, open-source library libavcodec in the project FFmpeg since June 2003. FFV1 is also included in ffdshow and LAV Filters, which makes the video codec available to Microsoft Windows application that support system-wide codecs over Video for Windows (VfW) or DirectShow. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000.
For long-term preservation of digital video sustainable container formats as well as audio/video codecs are necessary. There is no consensus to date among the archival community as to which file format or codecs should be used for preservation purposes for digital video. The previously proclaimed encodings were Motion JPEG 2000 (lossless) and uncompressed video.
Underneath a big clock
At the corner of 5th Avenue and 22nd Street
I stood and waited for a girl I knew
At the spot where we agreed to meet
It was four minutes of two
At four of two, I stood waiting for the girl
I was four minutes early for the date we had planned
I was planning to say I was in love with her
Just as soon as she showed for a two o'clock date
And the clock said four of two
At four of two, I was staring into space
She was not yet late, according to the clock
I was feeling nervous so I kept looking up
At the clock sticking out of the side of the building
And it still said four of two
At four of two, I began to feel tired
And I rubbed my eyes, and again I checked the time
It seemed as if the sky was growing dark
But I felt reassured when I looked at the clock
And it still said four of two
I lay my head down on the sidewalk
So in case she were coming I would have a better view
But no one was there so I stretched out
And closed my eyes for a second or two
It was four minutes of two
At once I awoke to a futuristic world
There were flying cars and gigantic metal bugs
I'd grown a beard, it was long and white
But I knew that the girl would be coming very soon
For though everything had changed, there was still that clock
