Bug ID: 23404
Summary: Redesign line position settings
Product: TextTracks CG
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: WebVTT

In bug 20037 we've redesigned text position settings.
This bug is about the "line" cue setting.
"line" settings position lines of text off the top of the video. With
snap-to-lines set (i.e. non-percentage values) the video viewport is divided
into lines and the positioning is by line number.
With percentage, users expect 0% to refer to the top of the cue box, 50% refer
to the center of the cue box, and 100% refer to the bottom of the cue box.
Right now the rendering algorithm does so by positioning the x% point of the
cue box at x% of the video viewport's height (for horizontal cues; width for
vertical cues).
However, this leads to hard to authoring content, e.g. to position the top of a
cue box exactly 20% down the video viewport, an author needs to make
complicated calculations to determine the "line" value that position equates
to.
