Need to convert FLV to MP4?

To add video files for conversion, click the Add Media button in the upper left corner of the interface, then choose Add Video, and select the files you want to convert.

Before conversion, you can make changes in the files you’ve added via the built-in editing tool. To access it, click the Edit button in the file description.

Among the tabs in the new window, choose Stabilization to reduce shakiness in your videos. Choose Audio to reduce background noise or otherwise alter the sound volume in the files. Open the tab Adjustments to change the parameters of brightness, saturation, contrast, and others. In the tabs Subtitles and Watermark, you can insert upload subtitles or add a watermark, respectively. Choose either Trim, Crop, or Rotate to get rid of unwanted details, cut away the edges of your videos, or rotate the footage.

You can reduce the size of particular large files by using the converter. Click the file size value in the description section. In the box that opens, select the desired quality, bitrate, and size values. Click the Convert Sample button to convert a small fragment of your file and check out the quality.

Click the Video tab. Choose the MP4 preset group, then the appropriate preset. If you want to transform FLV into MP4 for compatibility with your mobile device, click the Devices tab and then locate your device model.

To convert MP4 to FLV, simply choose FLV as the output preset.

Converted files are saved to the Movavi Library folder by default. To change the output folder, click the Folder icon. After you have specified all the required settings, click Convert and wait for the conversion to be completed.
