Creating Youtube (mp4) from mp3 and image

[robertpnl]

Hi,

I'm trying to create a Youtube movie from mp3 and picture file (which of course a still image is during playing the movie).
The creating process must be done by a commandline (automatisch process), so I try ffmpeg but without success. Avi will be successfully, but Youtube play not the full video because Youtube don't accept avi files greater than 1 Gb.

So I try it with mp4.

First, I create a simple avi:
ffmpeg -i sound.mp3 -i image.jpg -s 1280x720 -f avi out.avi
A avi is present and plays well (image is showing).

Then I like to convert this to MP4, but no success:
ffmpeg -i out.avi -acodec aac -ab 96k -vcodec libx264 -fpre
"libx264-default.ffpreset" -s 1280x720 -strict experimental out.mp4
(OS is Windows so i use -fpre instead of vpre).

A mp4 is present but during playing is no image displaying. Also Youtube failed this file after uploading.
Can someone explain why this happen? Thanks!

Hi
This is the command that I use:-

ffmpeg -loop_input -i image.jpg -i sound.mp3 -shortest -b 1000k -acodec copy out.mp4

Before you start, resize your image to 1280x720 or whatever size you require.

EDIT
We can also use x264 codec instead, like this (Linux):-

ffmpeg -loop_input -i image.jpg -i sound.mp3 -shortest -vcodec libx264 -vpre default -acodec copy out.mp4

It results in a smaller file size with similar video quality.

Long ago, I came across a free but nice utility accepting .jpg + mp3 (wav) --> AVI/mp4/flv, jpg2avi or something like that.
which gave me good results with nice quality.

Hi
I've added information about x264.

Thanks. With using the libx264 as videocodec, the output file is considerably shorter. Better for the upload time .
