NCH Prism free video converter is a capable, easy to use tool which can convert videos between most formats including some uncommon ones one by one or in batches. The clean, efficient user interface avoids the garish backgrounds and styling common to freeware video converters. Recent updates have also included FLV encoding and preview conversion output. Preview feature can be used to sample the original file and observe what the output video file will look before converting the video file. It helps in ensuring accuracy and the best output results. One of the cons is that the software is not available for free. One must purchase it to get it to work beyond trial period.
The cross platform conversion tool can convert videos from a large range of formats into AVI, ASF, WMV, MP4, 3GP and others. The tool has also the ability to convert DVDs into several other different formats. NCH prism is handy for anyone who needs to convert video files to watch on TV, cell phone, upload to a website or create a presentation. Besides, the app includes a number of useful tweaks and customization one can make to each file in the process of conversion. There is an option to set the compression/encoder rates of output files, set the resolution and frame rate of output files and set a specific size of output files. While in hurry, the user can add the files to the conversion list and prism will perform a batch conversion of the files. The application can also be minimized to run in the background. Although the application is lightweight, the conversion process can take some time depending on the format one wish to convert.
