Step 3 Crop video to best fit

There are 4 different methods when cropping video to focus video. We will need to talk about each case individually.
Before we talk about the 4 methods, we will need to know some terms when crop video.
Source Video: Source video is the video file you want to convert to other format.
Crop Area Size: Crop Area Size is the retained video area after you cropping your video.
Output Video Size: Output video size is the size of the video after you convert your source video

Method 1 Make the Output Video Size the same with the Crop Area Size

The method suits those who do not care about or whose players do not
require the size of the Output Video Size. However, this method does not
suit those who want to watch the cropped video on iPod, iPhone, iPad
and other portable players.

1. Press the button of "Crop" to open the editing window.
2. Drag and drop the crop area to best fit. You will get final Crop Area Size like 964*541

3. Click "OK" to save the setting.
4. Click to open the "Advanced Setting" Window.
5. In the "Advanced Setting" window, click "Advanced" tab.
6. Click the "Video Size" Drop-down and overwrite "Auto" with exact size that Crop Area Size shows.

Method 2 Make the Crop Area Size the same with the Output Video Size

The method suits those who care about or whose players require the size
of the Output Video Size. The disadvantage is that the method will lose
certain video footage.
If the output video size is smaller than
the original video file and the ideal crop area size is bigger than the
output video size, for example, if you want to play video on iPod,
iPhone, iPad, Android phones and other portable players, the output
video size will be usually smaller than the original video file. If the
crop area size is bigger than output video size, new black bars will be
added to top/bottom or left/right side to adjust the output aspect
ratio. Make the crop area size the same with the output video size is
the best way to remove black bars and to focus video. Bad thing is that
you will miss some video footage.

1. Click beside the "Profile" to open the"Advanced Setting" Window. "Video Size"shows like "720*480".
2. Press the button of "Crop" to open the editing window.
3. Drag
   and drop the crop area to best fit. And make the ratio of Crop Area
   Size to be the same with "720*480". If there is black bar in the output
   preview windows, this means the aspect ratio is different with that of
   the output video size. You will need to drag and drop the best area to
   make sure there is no black bar in the output preview window.

4. Click "OK" to save the setting.

Method 3 Keep the aspect ratio of the Crop Area Size with that of the Output Video Size

This method mostly suits those who want the output video keeps the same
aspect ratio with the source video. For example, the aspect ratio of
your source file is 16:9; you will also need the aspect ratio of the
output video to be 16:9.

1. Press the button of "Crop" to open the editing window.
2. Drag
   and drop the crop area to best fit. If there is black bar in the output
   preview windows, this means the aspect ratio is different with that of
   the output video size. You will need to drag and drop to adjust the Crop
   Area Size to make sure there is no black bar in the output preview
   window.
3. Click "OK" to save the setting.

Method 4 Stretch the Crop Area Size to Full screen

This method suits those who care about the size of the Output Video
Size and who do not want lose certain video footage. The disadvantage is
that images are stretched. It is bearable if it stretches a little bit.
You can view the result in "Output Preview" window.
