FLV Joiner is a portable tool that can quickly join multiple flv videos. The process is blazing fast and lossless simply because it doesn’t recode the file. All it does is to stitch the flv videos together.
It could be useful in many cases where you want to download multiple parts of the video and then join them quickly. The total time of the combined files and the total file size are also shown, pretty neat tool if you ask me.
There is no limit on the number of files you can add. To combine more files, hit Clear to clear the list and then start adding more files. It has been tested to work on FLV1/H263, VP6, AVC/H264, and VFR flash video formats without any problems.
Please note that it will join the files based on the order in which they have been added. You can move the files up and down by using the arrows given on the right side.
