RECORD DESTINATION AT rect
PUT object RECORD DESTINATION AT 13 47 173 167
yields a playback video size of 160x120 ((173 - 13)x(167 - 47)).
If either the width or the height of the rectangle specified with the RECORD and DESTINATION keywords (indicating playback video size) is not a multiple of eight, that value is rounded to the nearest multiple of eight.
Use the WHERE object RECORD DESTINATION ADJUSTED command to obtain the actual size of the playback video.
