Convert JPG to Video for playback in VLC

imagesjpegvlc-media-player

Is this a quick/simple way to convert a bunch of JPG stills into some sort of video file so it can be played back in VLC? If the convertion can be done using VLC, that would be preferred.

You can use a "stopmotion" maker: here's an overview of them, and one to download: CellSoft Take5 1.30

Even you can also use Picasa 3 which has a feature that does exactly this - basically, it saves the slideshow into a saved video file - works nicely.

Same frame rate for input and output

ffmpeg -loop 1 -framerate 10 -i in.png -t 30 -pix_fmt yuv420p out.mp4

Because the output will inherit the input frame rate you only need to declare the input frame rate if you want both the input and output to have the same frame rate.
The default frame rate for the image file demuxer is 25, which is the value that will be used if you omit -framerate.

Different frame rate for input and output

ffmpeg -loop 1 -framerate 10 -i in.png -r 25 -t 30 -pix_fmt yuv420p out.mp4

This example will use a frame rate of 10 for the input, and 25 for the output. Frames will be duplicated to go from 10 → 25. If the values are swapped, then frames will be dropped to go from 25 → 10. The console output will inform you if frames are duplicated or dropped.
The image file demuxer uses the -framerate private option to set frame rate. The output uses the -r option to set frame rate.
If you want frame interpolation try slowmoVideo.
