Is there a free program that I can use to convert MKV videos to AVI? I tried ffmpeg but it didnt work for me.
I can recommend three.
One: HandBrake. This tool is a free and open-source multi-threaded transcoding app. It supports nearly any videos including WMV format and has Mac version and Windows version.
- It is too professional to handle for most people;
- It doesn't support MOV as output format.
Two: iDealshare VideoGo. There is a step by step guide how to use this tool.
- Not free.
Three: Online-Converter. This kind of converter does a great job on file conversion.
- Like most online converters, the free version of this tool only allows you to convert videos smaller than 100MB. It's too small for video conversion;
- Your MKV video should be upload to the internet to be converted. This means the risk of pravite information leak is possible.
Transmageddon is another solution. It is available in the repository for Ubuntu/Mint Linux or Deb versions. Not batch capable. But, It WILL transcode .mkv to another format (vid & audio) or audio only if you just want an mp3 audio file. Free works pretty good. :)
You could try this mkv to avi converter. It is an online service. The file upload limit is 150MB, but you can use it for free and as many times as you want.
mencoder input.mkv -ovc copy -oac copy -o output.avi
That said, there may be one little issue with this particular conversion, which may also be the reason you could not use FFmpeg directly. The AVI format does not support all the video and audio codecs that may be included in the Matroska format. For example, you may need to recompress the audio stream to a supported format:
mencoder input.mkv -ovc copy -oac mp3lame -o output.avi
Absolutely, there are many. I will suggest you 2 programs that I use always.
