After I converted a video with Freemake Video Converter, the sound is ok, but the video is black (green). What should I do?

1. Please make sure you use the newest version of Freemake Video Converter http://www.freemake.com/downloads/.

2. Make sure that the original video track doesn’t have any issues. Watch it in a media player.

3. If the original video is OK, then try to turn off acceleration. Start Freemake Video Converter. Go to File->Options->Acceleration in the program and uncheck all accelerations, then retry to convert the file again, it may help.

4. Please make sure that your graphics card drivers are up-to-date.

5. If you have a .ts file, please don’t edit TS video; it may help to avoid such problem.

In case it didn't help, please follow this guide to completely reinstall the software, and when you are done turn off the acceleration again.
