Last Frame of Video and Audio Tracks
The last frame of the
video track
can be calculated as follows:
00:00:01:20 + 00:00:00:10*4 (4 loops) – 1f = 00:00:03:04.
As an IN field is defined at 00:00:00:10, the last frame of the video track of the GX Clip is
00:00:03:04 – 00:00:00:10 = 00:00:02:24 .
The last frame of the
audio track
of the GX clip is 00:00:03:00 – 00:00:00:10 -1f =
00:00:02:14 .
Duration of the Video and Audio Tracks
The duration of the video track in the GX clip can be calculated as follows:
(OUT-IN+1)+#loops*(OUT-Loop+1) =
(00:00:01:20-00:00:00:10+1)+4*(00:00:01:20-00:00:01:10+1) =
00:00:01:11+(00:00:00:11)*4 = 00:00:01:11+00:00:01:19
00:00:03:05
Duration of the GX Clip
The GX clip length always has the length of the longest track:
•
Without the 4 video loops, the GX clip would last 3 seconds since the audio track
would be longer than the video track.
•
As 4 video loops have been defined, the video track is longer than the audio track.
In this case, the duration of the video track, that is 00:00:03:05 , is the longest one, hence
gives the length of the GX clip.
