Convert PNG into MP4!!

[Cauptain]

Hi all,

I'm having a hard time and would like the help of you guys.

I have 200 png files and would like to convert each of them into 640x480, 30 second mp4 video.

How to do in batch mode?

There are a million threads here on how to do that with ffmpeg in a batch file.

I know this jagabo and I know how to do it.

ffmpeg -r 30 -loop 1 -i %d.png -c:v libx264 -t 30 -pix_fmt yuv420p out.mp4

The problem is I dont know how to keep the png file name equal to mp4 on batch. Like "exodus.png = exodus.mp4"

This is my doubt.

Use the CLI's FOR loop processing.

for %%a in ("*.png") do "g:\program files\ffmpeg\bin\ffmpeg.exe" -y -loop 1 -i "%%a" -vf scale=w=640:-2 -c:v libx264 -preset veryfast -tune stillimage -pix_fmt yuv420p -t 30.0 -r 30.0 "%%~na.mp4"

That will give you 640xY where Y is the correct height (mod 2) to retain the aspect ratio.

Thank u again Jagabo. Has made a convert.cmd and work like a charm.

If you want 640x480 regardless of the source image's aspect ratio:

for %%a in ("*.png") do "g:\program files\ffmpeg\bin\ffmpeg.exe" -y -loop 1 -i "%%a" -vf scale=640x480,setsar=1/1 -c:v libx264 -preset veryfast -tune stillimage -pix_fmt yuv420p -t 30.0 -r 30.0 "%%~na.mp4"
