Aiseesoft MKV Converter

Aiseesoft MKV Converter 9.2

Convert MKV and many other video and audio files between formats in batches
9.2.10 (See all)

Despite its clear reference to MKV, Aiseesoft MKV Converter is actually a multi-format conversion tool that not only transforms any MKV video into a smaller file that handheld devices can play back, but that also converts videos between any of the many codecs it can deal with. All popular formats are supported, and most of them for both the input and the output. Besides, you can also extract any audio stream present in your video files and save it as a standalone audio file in more than a dozen different lossless and lossy formats.

Both the program’s interface and the setup for the conversion processes resemble those in most similar tools. You can select any number of video files in any of the formats supported for conversion, assign the same or a different output format to each item on the list, and click on the “Convert” button to launch the re-encoding process. The fact that it can convert in one go different files into different formats – or even the same file into various output formats – is a bonus that you don’t find easily in most of its competitors. As expected, the app counts with its own media player for you to preview and double-check the files selected for conversion.

Another great asset is the list of output presets or profiles that the app offers to its users, not only because of how it simplifies the conversion process for less experienced users, but also because of the impressive variety of formats, devices, and codecs included on the list. It comes with specific sections for 3D, HD, and 4K video conversion, complete with all the settings required to produce high-quality, high-resolution videos in no time. Audio formats are also very well represented, with a separate section for lossless audio codecs. You can use these profiles either to extract audio streams from your video files or to convert audio files between formats.

Video files can be tailored to meet your preferences prior to launching the conversion process. The program’s built-in video editor will let you crop, clip, rotate, improve the video lighting values, and add watermarks to any file on the list. You will also find a tab for 2D-to-3D conversion, where you can choose any of the most common 3D anaglyph and split-screen modes available.

The conversion process itself is not precisely lightning fast. High-quality video conversion takes time, just as all good things in life. Aiseesoft MKV Converter is in line with most of the video and audio conversion tools available in the market, also in terms of cost. It offers a high level of versatility and a level of flexibility somehow higher than that of most of its competitors, thanks mainly to its support for multi-output conversion. All in all, this attractive conversion tool is – among the dozens of similar tools out there in the Web – at least worth a try.
