Until recently, sign language researchers were quite happy with just one or two views for each recording session. While ELAN allows the user to relate several media files to a transcript and to sync them, iLex just allows one single media container and relies on the container format, such as QuickTime, to group and sync several video streams into one container. In order to save screen real estate, iLex offers the user the possibility to switch on or off individual tracks within the media file. This works quite fine with two or three different views grouped, but fails to provide an adequate solution in multi-view projects such as Dicta-Sign or DGS Corpus with seven cameras altogether for a pair of informants. The advent of HD videos makes screen real estate really an issue: Even on very large screens, video competes with transcription space. Here we present a user interface study that allows flexible switching between video layouts whenever the transcription focus changes. Switching (including zooming and cropping) may be initiated at any point of time by the user, or can be automated to depend on tagging such as tasks or turns. This user interface is backed up by a server infrastructure providing videos in different spatial resolutions as needed for optimal display while saving transfer bandwidth and local processing power which even nowadays becomes an issue when dealing with several HD videos in parallel.
