Tarkovsky Films Now Free Online
http://www.openculture.com/2010/07/tarkovksy.html
Andrei Tarkovsky (1932-1986) firmly positioned himself as the finest Soviet director of the post-War period.
Ingmar Bergman went so far as to say, “Tarkovsky for me is the greatest [director], the one who invented a new language, true to the nature of film, as it captures life as a reflection, life as a dream.”
And Akira Kurosawa acknowledged his influence too, adding, “I love all of Tarkovsky’s films. I love his personality and all his works. Every cut from his films is a marvelous image in itself.”

sRGB vs REC709 – An introduction and FFmpeg implementations
1. Basic Comparison
- What they are
- sRGB: A standard “web”/computer-display RGB color space defined by IEC 61966-2-1. It’s used for most monitors, cameras, printers, and the vast majority of images on the Internet.
- Rec. 709: An HD-video color space defined by ITU-R BT.709. It’s the go-to standard for HDTV broadcasts, Blu-ray discs, and professional video pipelines.
- Why they exist
- sRGB: Ensures consistent colors across different consumer devices (PCs, phones, webcams).
- Rec. 709: Ensures consistent colors across video production and playback chains (cameras → editing → broadcast → TV).
- What you’ll see
- On your desktop or phone, images tagged sRGB will look “right” without extra tweaking.
- On an HDTV or video-editing timeline, footage tagged Rec. 709 will display accurate contrast and hue on broadcast-grade monitors.
