If I join two videos on the timeline and only add a transition between them and export the same, will the software re-render the whole video or only the transition part? or is it capable of streaming the video without re-encoding (except for the transition element). Please tell me how to go about this if it is possible. My video is 1280 x720 @ 25 fps and codec h264
One more query is
Does the transition actually cut the two videos equally i.e. cross transition or does it just apply the effect to the end of the first video only without relating to the subsequent video??
