I am trying to convert several MPG4 files to AVI format so that I can edit a video using Windows Movie Maker. I downloaded a free converter called Converter Lite, which is really simple to use. Once I get the video converted, my computer is not able to play the video due to a missing codec file. I did some troubleshooting on Converter Lite's website, found a new code to insert just before converting but still no luck. The video will not play in Windows Movie Viewer or in Movie Maker. What the hell?
On Converter Lite's troubleshooting list, the following is what I felt applied to my issue:
Won’t convert MKV to AVI
MKV files use an aac audio codec which can contain more than 2 audio channels. When you convert MKV to AVI you also convert the audio codec to mp3. Mp3 audio codecs can only hold 2 audio channels. So if your MKV file had more than 2 audio channels and you convert to AVI it may not play. This mans you need todo one of 2 things:
1) Force the number of audio channels to 2 (Will downgrade the quality of the audio)
2) Keep the audio codec as aac (We haven’t tested it yet)
Here’s how to do it:
1) When choosing AVI and the AVI quality, click settings and then you will see the ffmpeg arguments. Go to the end of the arguments and add a space. Then type the following, “-ac 2″. Then click convert and it should work fine.
2) When choosing AVI and the AVI quality, click settings and then you will see the ffmpeg arguments. Look for where it says, “-acodec libmp3lame”. This is what changes the audio codec to MP3. So what we want to do is change this to an aac codec. We do this by deleting the code “-acodec libmp3lame”, and adding instead, “-acodec libvo_aacenc”. (make sure there’s a space added before inserting “-acodec libvo_aacenc”.
Anyone have any ideas or recommendations?
