WinX FLV to MP4 Converter is a free video converter. It allows you to convert flash videos (FLV) to the MP4 container. You can choose from MPEG-4 or H.264 to encode the videos. Some people say H.264 is the format of the future. I see that most high definition content that is released online is encoded using that codec.
This free converter is fully functional and can convert full-length videos. Since it is a free tool, it lacks most of the flair of the paid versions, and you won't see the features that you are used to see in trial converters. For example, there isn't a video player or editor, and there aren't any conversion profiles for specific devices.
In my testing, I converted two different files that I had downloaded from YouTube. One of them had a problem with the audio. If I set the volume too high, the file started to sound weird, just like when you download a poor quality song from the Internet. I realized this is because the converter automatically increases the volume of files by 8 decibels. The second file had a video and audio sync problem. The video was going too fast.
- Video conversion worked well
- Easy to use
- A video/audio sync problem
