I want to play two videos combined together. Can you help?
In order to combine two videos together, I suggest you use a utility from Software Informer database. You can try Free Video Joiner, FormatFactory, Kate's Video Joiner or Free Video Cutter Joiner. All of them are free of charge and beside the merge feature, they have many useful options. Once you combine the videos together, you can open them with VLC Media Player which supports all major video and audio formats.
Share an easy-to-use video joining tool called Joyoshare Video Joiner with you. You can use it to combine two videos without quality loss. By the way, it offers a trial version that allows you to use it for free ten times.
