First, you need to know what video or audio format you have and what format you want to convert to. For example, if you want to put video on your iPod, you need to convert the video to MP4. If you received video created on Mac, you probably need to look for something that can convert MOV to other windows media support, like WMV.
Top video converter software should convert common formats like WMV, AVI, MP4 and MOV to similarly common formats. The best video converter is defaulted to the most common settings, but powerful enough to customize. The interface should be intuitive and user-friendly.
Basically, we use the following 5 criteria to evaluate video converter software.
- Input Files - Top video converter has maximum compatibility and could convert a wide variety of input files. The more video and audio formats the video converter can conver, the more powerful the video converter is.
- Output Files - A handful of formats is enough for most users, but the best video converter software will still provide a broad selection of outputs formats.
- Features - The top video converter software includes the ability to adjust multiple advanced options including video size, codecs, bitrates and framerates. Most features are reserved for advanced users, but they should be readily available and easy to find.
- Ease of Use - Top video converter should be user-friendly and intuitive. Tool bars, buttons and menus should be clearly labeled and self explanatory.
- Help and Support - All top video converters are easy-to-use, and manufactures should include a detailed in-program guide, a FAQ online and an email contact.
