I can't put these MP4 videos on my Apple devives?

I converted these animes to MP4. I can put them on Itunes and Play them there but they cantd be put on my apple devices such as my Iphone or Ipad. Its odd. It will say this video can't be added to device…

Just wondering, can you connect the devices to your computer via a cable then drag and drop?

Most likely it was a bad converter that did not use the correct audio or video codec to suit Apple's MP4 specification.

Try converting them again, but use Handbrake and pick one of the iphone/ipad compatible output formats.

I use that for video conversion and it definitely produces compatible files when working with Apple devices.

Apple can't play MP4… Just another reason I hate Apple. You'd need to convert it to m4w. Though that usually results in a big loss of quality.
