RMVB to MP4 and then some...

[ChillWinterheart]

I wanted to upload the opening song of an anime series to YouTube. but I only have its episodes in RMVB format, and YT doesn't accept that; they want it in MP4.

Since money is out of the question, I searched for freeware and used the RMVB converter from RMVBcodec.com. Conversion went through ok [or I think it did...] then I used X2X Free Video Trim to grab the opening song and get rid of the rest.

I double-checked the finished product. The sound is in sync, the video's ok. Uploaded it.

I watch it in YouTube and... IT'S HORRIBLE!! The song plays on quadruple speed [although the video plays at normal speed] and the music skips and fizzles and pops.

What just happened? Did I do something wrong? I read through the guides that I have to choose a certain audio codec for my video to make sure that the music would be in sync, but

1. I didn't bother with it since the opening song was playing fine before I uploaded it
2. After finding out that it was messed up, I discovered that neither the RMVB converter or the video trimmer had the option to control the sound.

I don't know if the problem was with the converter or the cutter program.
help?

Any Video Converter will convert to mp4, and it allows you to trim the videos. It works well. Earlier today I used it to do the exact same thing you are doing to upload this video. For some reason I could not find this video in Japanese.

MediaCoder - more than a universal audio/video transcoder It just works.
