auto correct time values: automatically correct start/end-time if a conflict appears.

transcript mode: current time to start-/end time buttons will be always visible in the titles` list. Work in this mode if you have imported a transcript.

minimum time value between titles in milliseconds: the gap between titles, when functions like glue, split or auto correct are used.
 
http mode: only relevant if you're video isn't on a streaming server or youtube. This will affect the behaviour if you seek in the video, e.g. through the scrub-bar or clicking on a title in the titles` list

• pretend: the tool will pretend that the video is at the shown time (e.g. if you want to scrub at 00:04:125 but the closest keyframe of your video is at 00:04:000, the video will jump to 00:04:000 and 00:04:125 will be shown as current time)
• real time: the tool will show the real time of the video (e.g. if you want to scrub at 00:04:125 but the closest keyframe of your video is at 00:04:000, the video will jump to 00:04:000 and 00:04:000 will be shown as current time)
• search keyframes: search for key frames and play to the right frame of FLV when skipping/scrubbing (e.g. if you want to scrub at 00:04:125 but the closest keyframe of your video is at 00:04:000, the video will jump to 00:03:000 play to a value very close to 00:04:125 and 00:04:125 will be shown as current time)
