Merge multiple x264 videos?

Question

Video processing

There are a lot of 5 minute webcam video files.
File names look like this Camera Address_YearMonthDay_HourMinuteSecond.x264 The size of each file is ~60mb.
Tell me how, for example, 24 five-minute files can be glued into one 2-hour fragment, and saved in the popular avi or mkv format.
A simple program for dummies (OC Windows) is desirable.

Answer 1

ffmpeg

Answer 2

For gluing, I found SolveigMM Video Splitter. It has a gluing manager, you feed 50 x264 files, you get 1 x264 file at the output.
It is most convenient to convert to ffmpeg, for all the scaryness of the manual, it is enough to put the file in the root of the disk, type ffmpeg -ic:\file.x264 c:\file.mkv and wait.
