Using Crop Scale

When you import video files of one aspect ratio and then change the aspect to a different value for the output video, there can be two different situations which can be solved in a similar way:

the input files have the 4:3 aspect and the output file will have the 16:9 aspect ratio – in this case the mattes will be added to the left and right sides of the video image to prevent distortion;
the input files have the 16:9 aspect and the output file will have the 4:3 aspect ratio – in this case the mattes will be added to the top and bottom sides of the video image to prevent distortion.

In both these cases you can get rid of the mattes using the Crop Scale option available in AVS Video Editor. Select the necessary aspect ratio and click the video at the Timeline with the right mouse button. Choose the Crop Scale option. The Crop Scale window will be opened:

In the above figure you can see an example of the first above case of the aspect ratio change – an input 4:3 video image changed into an output 16:9 video file. As you can see, mattes are added to the sides of the video so that it could fit an 16:9 frame (the black bars on top and bottom of the video are added simply to fit it into the square player window and will not actually be added to the output video).

Now if you use the Crop Scale field field and click the Crop Scale button button, the slider Crop Scale slider will become available that will let you change the visible part of the video. Move the slider using the mouse to get rid of the mattes:

Note: using the Crop Scale function will enlarge the video image so that it could fit a new frame size with an aspect different from that of the original video. It means that a part of the video, namely some video image at the top and the bottom parts will be cut out and lost.

And this is how your transformed cropped video will look like in the Preview Area:

As you can see, the resulting video has no mattes on either side. At the same time it is slightly enlarged and cropped on top and bottom. So you will have to decide what is more important for you: have video fit your display or TV-set screen or have the whole source video image.

Using Trim and Multiple Trim Options

AVS Video Editor - Using Trim and Multiple Trim Options

After you add your video to the Timeline/Storyboard Area and edit it, you can still trim it and detect scenes and insert transitions between them.

Click the main video area at the Timeline and use the Trim button of the Timeline Toolbar to open the Trim window. Or alternatively click the video at the Timeline with the right mouse button and select the Trim option.

Please read the Trimming Video section to learn how to use the Trim option.

The same way the Multiple Trim option can be used to find scenes in your video added to the Timeline/Storyboard Area. Open the MultiTrim window either clicking the MultiTrim button of the Timeline Toolbar or using the right mouse button on the main video at the Timeline and selecting the MultiTrim option. The opened MultiTrim will look like this:
