An easy way to combine audio & image into video?

[Aquinax]

I'm searching for a way to combine an audio & an image file into video. I have various software - SolveigMM Video Splitter, Handbrake and MKVtoolnix. Can any of the mentioned programs accomplish this? If not, what can?

Assuming your audio is MP4-compliant:

ffmpeg -loop 1 -i myimage.jpg -i myaudio.m4a -c:v libx264 -c:a copy -shortest myoutput.mp4

Thanks, JVRaines,

I've tried a very similar command, a few times, and at the end of the process I receive the following line of request:

Enter command: <target>|all <time>|-1 <command>[ <argument>]

to which I don't know what to reply and as the resulting video is not yet produced in the ffmpeg folder, the random keys which I press usually lead to a flawed result. Do you happen to know WHAT one should type, in response to that request?

[JVRaines]

Try adding "< /dev/null" or "< NUL" (Windows) to the end of the command.

or VirtualDub:

1) open image file with File -> Open Video File.

2) Video -> Frame Rate. Set source rate to 1/seconds, where seconds is the desired length of your video. Ie, if your song is 2 minutes long enter 1/120. Set Frame Rate Conversion to a typical video frame rate. Say, 30 fps.

3) Video -> Compression. Select a compression codec and configure it.

4) Audio -> Audio From Another File, add your audio.

5) File -> Save as AVI.

Or ffmpeg with a script like this:

SET PATH="C:\FFMpeg\64-bit"
for %%a in ("*.mp3") do ffmpeg -r 10 -loop 1 -i img.jpg -i "%%a" -c:v libx264 -pix_fmt yuv420p -crf 22 -c:a copy -shortest -f mp4 "%%~na.mp4"
pause

JVRaines, jagabo, racer-x, thanks very much for your replies.

I've settled for now with FFMpeg, creating video out of an image, and next merging it with audio in MKVToolnix. I'm using the following line:

ffmpeg -loop 1 -i "myimage.jpg" -c:v libx264 -t 60 -pix_fmt yuv420p -vf scale=1280:720 out2.mp4 < NUL

.. and I get a 25 fps still video - can I specify the command, that the video is 30 fps? Thank you.

[jagabo]

Add "-r 30" after "-t 60".

Alternatively ",fps=fps=30" can be added to -vf, side to this i would add "-tune stillimage" and i would try to reduce video bitrate by involving pulldown on x264.

Should "-tune stillimage" improve this sort of video (still image) ?
In regard of "pulldown on x264", could you, please, give me an example? thank you

Short answer: Yes

In regard of "pulldown on x264", could you, please, give me an example? thank you

Seem that pulldown works only in x264 not libx264 (ffmpeg use libx264) as such you may consider to use pipe from ffmpeg to x264 to fully use H.264 syntax capabilities...
