Just below Profile is Output, here you can browse your computer for a better destination folder for Video Converter to save your converted movies. Simply select a proper output format to reduce the video size such as MP4, FLV, 3GP etc, because they are usually smaller than other files due to high compression rate.

Step 3. Start to compress video files

Clicking the "Settings" button ( at the right side of Profile bar) to Enter "Settings" Window, then you can lower the value of size(important), bitrate (important), frame rate. According to our multiple tests, the file size and video quality is based more on bitrate than resolution which means bitrate higher results in big file size, and lower visible quality loss. Of course, the size (resolution) is also important.

Step 4. Save the compressed video files

Click "Convert" to export your vidoes after compression, then you will sucessfully shrink video files to smaller size.

Suggestions for Common Video Compression Settings

Normal Compression:

Normal compression reduces the file size and keeps the video quality as much as possible. There are different ways on how to make video files smaller, and the popular ways include re-encoding with an effective video transcoder and using a file compressor.

Loseless Compression:

The goal of loseless compression is to contain all quality of the original video. However, this is not so useful because it barely decrease the amount of data on a video. And most people want to do a video compression with the goal of reducing the video size.

* You're highly recommended to compress your video as H.264 in MOV or MP4 format, because they are usually smaller than other files due to high compression rate.
* The compressed file size totally depends on the compress bit rate. Normally, the smaller video you want, the lower bit rate. The bit rate also controls the image quality. Please mind that the image will totally be destroyed if the bit rate is too low.
* Besides，the codec also influences the compression. Mostly you can select H.264 here.
* In most situations, a ratio of 640 * 480 is sufficient. But it also depends on your need.
* The frame rate, frame size, or codec of the source image doesn't matter so much on video compression.
Knowing the video format, ratio and bit rate that influences the size of compressed video, it'll be much easier for you to select the best video compression settings.
