At this point, we can start scrubbing the video sequence by clicking and dragging
with the let mouse buton over the
Video Sequence Editor
; let's take a few
seconds to move around and see how the sequence editor performs the mixing
between the strips. Pay special atenion to how the two efect strips afect the
output and how the strips for the
item1
,
item2
and
item3
scenes also got the
customized transiion efect (in the frames that they overlap verically) that we
created by using the alpha channel in each of them.
17. To finish this task, we just need to set the output format for the final video and
iniiate the rendering process; to do that, go to the Default screen of the video
scene (make sure both "Default" and "video" are set before coninuing) of our ile,
then go to the
Render
tab in the
Properties Editor
and set the opions as follows:
F
Dimensions panel:
Start: 1
End: 700
F
Output panel:
Output path: /tmp/render/demoreel-
File format: MPEG
F
Encoding panel:
Format: AVI
Codec: H.264
Bitrate: 700 (raise it up if the video quality after rendering isn't good enough)
18. Now we can save the file and start the rendering process by clicking on the
"Animaion" buton (
Render
panel, in the
Render
tab of the
Properties Editor
).
Not much later, we will have our final demo reel ready to conquer the world!
Objective Complete - Mini Debriefing
In this task, we just took the previously rendered images and imported them into the Video
Sequence Editor as strips, so that we could use the efects and set some opions to get the
video composed by transiioning between them appropriately.
For the image sequence strips, we didn't make use of explicit transiioning efects; since we
already had a transiion "baked" into the alpha channel of the rendered images, it was just
a mater of seing the appropriate opions for these strips and puing them in the correct
verical, overlapping order (for example, the
item1
strip above the
item2
strip) to get them
transiioning automaically.
