mp4 video playerHow do I put video on an MP4 player?

I want to put an MP4 video file on my Sony Walkman MP4 player? I know it plays video, it has a video section. I downloaded the movie as an MP4 off of Limewire but for the life of me I can't figure out how to put it on. Can somebody please help?!
If you know how to put music on, .mp4 videos should be the same.

However, some devices need their own programs to transfer videos. Check out the website of the company of the product (ex. sansa.com) I have a sansa e250 and it needs SMC or Sansa Media Converter to transfer videos and pictures.
Sony walkman mp4 player only supports some special mp4 videos, like MP4(H.264/AVC video encode, AAC audio encode), you just need a right converter to convert your MP4 video to MP4(H.264/Amp4 video playerVC video encode, AAC audio encode), then you get the converted videos to play well on your Sony Walkman mp4 player. To convert any videos or audios between any different formats, you can try RZ Video Converter Lite which can do this well, such as convert any MP4 videos to MP4(H.264/AVC video encode, AAC audio encode) videos, etc. Try it by yourself. You can yahoo or google search and download RZ Video Converter Lite, easy to use, hope it can help you !

I'm afraid that common mp4 video can't be put on sony walkman due to it has specific video size requirement. you should change your current mp4 files or that video types to walkman supported movies.
If you need a converter, try a total free one. You need to consider video resolution, bitrate, aspect ratio, etc.
