I've got a few vacation videos that I'd like to turn into one long video. The issue is they come in both *.AVI and *.MP4 formats. What simple software out there will enable me to take both these formats, and stick the videos to each other? Obviously I'll have to convert them into the same format. The main issue is the merging of the videos together.
The soloution is to find the correct codec for virtual dub or find software that natively supports your file formats. That is my favourite free software, but for work I use Adobe CC (which is expensive) I would pop over to the virtual dub forums and ask them to help you, they are a friendly bunch. Failing that hope somebody else knows of a good piece of video stitching software that can use both formats and is easy to use
