Splitting: By splitting, you can chop a single video file into small segments so that you can extract or duplicate some specific scenes. The small clips can be change into GIF (Graphic Interchange Format) and upload to internet to share with your friends.

Joining: After joining, you can merge several videos into one file. For example, when you have downloaded a long movie in 4 smaller parts, a joiner will put all the parts back together again. However, this only happens on the condition that all the video files have a similar format (same resolution, bit rate and more).

I am using the demo version only at this time. When I convert a DVD, main movie only, to a MP4 my media player displays 6 files. Is that due to the demo software, media player, the way it is going to be, ??? I am prepared to purchase the software if it can truely produce a single file viewed as a single file by my media player (Sony TV).

Hello, Desiree. Aimersoft Video Converter Ultimate can surely fulfill you needs. Download the trial version to test it now!
I have been having some issues trying to find a program that will take a mp4 video split it and just resave that portion as a mp4. All the ones I have tried want you to reconvert the split portion into a mp4 format making the process even longer than just splitting it. I just want to take the mp4, import it, cut it, and save that portion of the mp4 video. That's it, no conversions to different formats. I tried YAMB but it makes the video stutter and I can't use Avidmux because I am running Windows 7. Any advice?? Does this software do just that?

Hi, eleni, thanks for your interest in Aimersoft products. For your case, please first check what video formats your media centre supports. And then import all the videos into Aimersoft Video Converter Ultimate, select Merge into One File to merge all the videos. After that, select a format your media centre supports as the output format. (Converting the videos to ISO is quite time-consuming, so you can turn to other formats instead.)
Could you advise how to easily take mpg4 files and put them in a format for playing on through a media centre. Currently I need to merge then burn onto a DVD and then create a .iso file which is very time consuming. I just got a new camcorder but am kind of wishing I had the old technology that just merged all the clips one after the other.
Not only a MP4 merger, splitter, but more: converter, trimmer, rotator, etc. Nice to find such a program!
