Need help with converting video to put on an mp3 player.?
I have an Sony Walkman NWZ-E344 and I want to put some videos on it. I use to have Windows 7 and when I wanted a video on it I would drag and drop it and it would convert the video to the right format. Now I’m using Ubuntu mostly because I’m a programmer and I like using it better but now I can just put the videos on the mp3 player because there not the right format.
Heres what video format it uses:
Video
Video Formats
(Codec)
Frame rate: Max. 30 fps
Resolution: Max. QVGA (240 × 320)
Windows
Media Video
9*4
Audio Formats
(Codec)
Media File format: ASF file format
File extension: .wmv
Profile: Main Profile, Simple Profile
Bit rate: Max. 768 kbps
* Compatible with WM-DRM 10
Bit rate: 32 to 192 kbps (Supports variable bit rate (VBR))
WMA
(for Windows Sampling frequency*1: 44.1 kHz
Media Video
9)
So I need to convert it to the format exactly but I’m not sure what program to use. Can anyone help me?
