Creating "fades" in AVIedit
What is the "fade" ? It is an impressive video (and
audio) effect that allows you to make nice transitions from
one piece of your clip to another. When you arrange your family
videos, you probably have noticed that they have some not very
interesting scenes, so cutting these would be really nice. Assume
you did the cuts... But now you have even a stronger problem to
solve. If you simply join these edited parts of video, the result
looks jerky as like the heap of disconnected LEGO puzzles.
It's time to add few fades between clips.
Lets begin. For a training purposes we
will "connect" two still image clips and add some music
to them, finally creating an avi file.
I've taken two well-known pictures, they have a bit different width and
height, but this is not a big deal. You can use your own photos, video
frames exported or video clips you may have.
Step 1
Start AVIedit and click Edit/Timeline or button.
You will see this dialog box.
At left side of the editor window you see the frame with two rulers,
on top and on bottom of it. They are marked with time units. You can
change the time scale for better views using the dropdown list at right side.
Step 2
Add first image by right mouse button click somewhere in the timeline.
Context menu appears and you need to choose Add Image item
as shown below.
Step 3
Now you see an Image Browser window that lets you preview and finally
select an image you'd like to add to timeline.
Step 4
Add second image using the same way as you did for first time.
Step 5
Align images to make them overlapped a bit. Left button click with SHIFT
key pressed starts the movement mode. You can change the clip placement
and leave the movement mode by left mouse button click. To assign some
transition effect, move the mouse inside the overlapped area and when
this area gets outlined, click left mouse button. You will see a dialog box
that lets you to choose an effect and some its options.
Maybe it is really hard to read about this. Please download one of these
two files and play training.avi file to see what exactly I meant.
training.avi 400K
ready to playback
training.zip 85K
requires WinZip or pkzip to unpack avi file first
Step 6
Now add some music to the video clip. Place the mouse below the leftmost
picture and click right button. Choose Add sound and locate an
appropriate wav file. It should be uncompressed PCM .wav file. AVIedit
will resample 22 to 44 kHz, 8 to 16 bits on the fly. No special care is
required. To cut off the piece of sound you do not like, first split the
audio track using CTRL+left mouse button click. Then delete the piece
you do not like, using right mouse button click (context menu).
Step 7
It's final step. It would be worth to save the project we just made. Click
Save button and enter some name here. This will save the current project
state to HDD. Next time you'd use Load button to get the project
for some further editing.
Of course, it's time to write out the movie. Click Make button,
specify a new avi file name and few make options. Next you'll be asked
about a compressor, and you'll need to relax a bit, while the hourglass
cursor tells you AVIedit is busy with your clip rendering.
I have selected DivX MPEG4 video codec and have set the bitrate to 360 kbps.
Here is the sample (146 kbytes DivX encoded).
That's all!
You may ask, what if the picture size is smaller than a movie frame ?
It is not a big fault! Look... Hit the right mouse button to
first image clip. You will see its context menu. Choose Properties and
check scale to fit frame option. Repeat this with second image
clip, too.
Happy fading !
