Video quality surely means much to any videoers, those with editing needs notably. In no situation is a lossy video converter acceptable nowadays, and we always appreciate small file size as much - both uploading & storage-wise. If you’d go with me for that matter, I say WonderFox HD Video Converter Factory Pro, a decent video converter that can absolutely help in your DaVinci video editing, could be the best solution here. It can convert any video to be DaVinci-friendly; It implements a good trade-off between video quality and size with advanced coding technology; And it allows you to customize video parameter like bitrate, frame rate, etc. What’s more, it has a pretty simple GUI.
