Hello im currently putting songs on my mums ipod 4 her,she wants videos putting on it,its a black 30GB video ipod,how do i put music videos on it?

Music Video's?

From where?

Youtube?

There are converters out there ,

I use dvdvideosoft.com's 'free YouTube to iPod converter'

I use it for my phone, but there is the option for video ipod and change of quality.

Thats it as far as i know, Drag and drop via Itunes?

noo i downlaoded videos from limewire and i tryed dragging and dropping them onto the ipod but they just say the ipod cannot play videos,but its a video ipod i know for sure.

Then the file format is not right.

You need to import the video into iTunes, then from the advanced menu select 'Convert Selection for iPod'. Then you can sync it.

iPod accepts only MP4 format video, if your video is not that format, you couldn't add it to iPod. If your video is MP4 video, open iTunes, create a playlist, drag your video file to the playlist in the iTunes library, plug in your iPod to PC, and then click iTunes "File" menu -> "Sync iPod', your video will be transferred to iPod. If you don't have iTunes, you can download iTunes free from apple official site:

If your video isn't MP4 format, you need third party software to convert video to MP4. You may try an iPod converter develped by Aimersoft; it embeds an iPod manager that can help you transfer DVD movie and video to iPod directly. It works really nice for me. Here is its official download link
