This was the time when there was no clear idea about how to define a film festival.  At that time, SEOUL International Women’s Film Festival came up with a catchphrase See the world through women’s eyes, setting its main goal to introduce women’s films that explore the “women’s reality from the women’s perspectives”.  Featuring films by women, for women, and of women, the 1st edition of SEOUL International Film Festival received a number of positive reviews from the audience, which was never anticipated this much.  Thanks to continuous support from the audience, SEOUL International Film Festival that used to be happening every other year has become an annual event since the 3rd edition in 2001.  For the 6th edition in 2004, SEOUL International Women’s Film Festival looked for changes by relocating the festival office and venues to Sinchon, the street of youth and culture.  For the 9th edition in 2007, the Queer Rainbow section was first introduced, presenting films about life and culture of gender minorities.  In order to go beyond the gender boundaries based on biological sex and to reach out for solidarity, SEOUL International Women’s Film Festival newly created the Open Cinema section encompassing feminist films made by male directors.  Now in 2015, SEOUL International Film Festival attempts to build its new festival identity and become a cultural platform more approachable for a wide variety of audiences by changing the official English title of the festival from International Women’s Film Festival in Seoul to SEOUL International Women’s Film Festival as well as by retouching the festival logo used for last 17 years.

24p: In video technology, 24p refers to a video format that operates at 24 frames per second (typically, 23.976 frames/s when using equipment based on NTSC frame rates) frame rate with progressive scanning (not interlaced).

Some vendors advertise 24p products as a cheaper alternative to film acquisition.

Three-two pull down: Three-two pull down (3:2 pull down) is a term used in filmmaking and television production for the post-production process of transferring film to video.  Film runs at a standard rate of 24 frames per second, whereas NTSC video has a signal frame rate of 29.97 frames per second.  Every interlaced video frame has two fields for each frame.  The three-two pull down is where the telecine adds a third video field (a half frame) to every second video frame, but the untrained eye cannot see the addition of this extra video field.  In the figure, the film frames A-D are true or original images since they have been photographed as a complete frame.  The AB and D frames on the right, the NTSC footage, are original frames.  The third and fourth frames have been created by blending movie fields from different frames.
