Key Features

Pros

Cons

Freemake Video Converter A user friendly application that responds well. With a simple design, it manages to do many of the tasks you will need when working with video files in several formats. Unfortunately, this software requires you to have .Net Framework installed, so it is not an option for Mac users, and even if you had Windows installed you need to make sure you have the right .Net version installed, otherwise wait for it to install (it is around 1 GB of space), too bad if you are in a bit of a rush. A simple interface, support for different types of files and a toolbox that will help you with most video conversion-related tasks. .Net Framework needed so there is no support for Mac or PCs without it, it does not allow you to set details on the conversion format such as bitrate or frames per second and this impacts on the final file size on your videos.
Free MP4 Video Converter Part of a big suite, this application has a good interface as well and lets you control most of the option you need on your output files, however if you want additional tools to work with, you will have to download each one of them, or download the entire suit, which has a lot of media software you probably won’t use. The problem with this application, amongst others is that you get a pop-up with advertisement every once in a while. A good-looking interface, it lets you control the output properties of your video and it offers a very good performance. It will only let you convert video formats: no DVD titles/burn support among other options, includes several windows that will annoy you here and there and once again, only support for Windows users.
Convertfiles.com Today it is very easy to find video converters online with no need for installation; these online converters usually work when you need an immediate solution, but don not expect much from their results. This is one example of it, this online converter allows you to convert virtually any kind of file .doc files, .pdf files, presentations, images, audio, video… almost anything. However, say goodbye to any options for the output file, you just upload it, choose what you want to convert it into and that is all. You can convert almost anything as long as you have an internet connection, simply select the type of file that you need it converted into and you are good to go. Since this is an online converter you will want to have a good upload/download Internet speed (yes, you have to wait for your converted file to download), also you have no chance to personalize the output file and you can only convert one file at a time.
Online-convert.com Another option in online conversion, once again you can convert between multiple kinds of files, not only video. However, in this you will also have the chance to modify the settings for the output video file. It is also useful that you can add your converted files directly to your Dropbox account. A cleaner online converter, easy to use on a lightweight page that allows you to have some control over your converted files including support for one of the main services for online storage. Once again, you depend on the quality of your internet connection (if you have any) to upload the files (and download in case you do not want to link your Dropbox account).
iConvert So far we have reviewed some options that are not available for Mac users, except for the online converters that you can use as long as you have a browser and internet connection. This one will work exclusively for Apple users, it has a simple interface, all you need to do is drop the files you want to convert in it, select the output format needed and hit ‘convert’, as simple as that. A simple application that looks great on Mac, easy to use and offering very good results. You can not convert multiple files at a time, it is not possible to change any settings for the final video and, basically there is nothing else you can do with this application.

AVI vs. MP4

We have so far seen why is MP4 superior on several aspects to AVI and some tools to convert between one another but, why should you use MP4 instead of AVI? MP4 is basically a container which can keep audio, video, subtitles and still images within one single file without making its size bigger. On the other hand, AVI files can contain video and audio and it allows a synchrony between them. AVI files can be easily created, they do not require any compression and there will be no loss of quality but its size will pay its toll by turning it into an extremely large file. While AVI files struggle with size, MP4 are usually compressed but this only makes it easier to be used for transferring or streaming so that its content can be watched online while it is being downloaded or as you need to keep the file sizes portable to see on any other devices. AVI is good as a recording file type, but when you need to transfer these videos into mobile phones, tablets, media players, all of these usually have limited storage sizes, so it is very important to choose a good format that will keep quality and takes little space. So in conclusion we can say that MP4 is a wonderful choice in today’s world, where we are constantly sharing moments and useful information with practically anyone that we want to, and Aimersoft Video Converter Ultimate is the best tool so you can do all of this in an easy, comfortable way.

Hi, I\'ve tried a couple of trial applications to convert AVI and WAV files to MP4, but the resultant quality (both audio and graphics) is terrible. When I use your software, will I lose any sound/visual quality, or will the output be of the same quality as the original file?

I have a knack for dumb questions, so here we go: I have old home movies on Hi8 video tape from a 2001 Sony Handycam. If I buy a cable to connect the AV output from the Handycam to a USB input, can I then use this software to locate and convert the analog feed to a digital format, and thereafter use the conversion, editing and burning tools? The cable sellers seem to think that I have no choice but to send the video tapes to a third party to perform the conversion to digital at their ridiculously high prices. Thank you.
