change fps while-loops exporting ffmpeg

I am new to FFMP开发者_StackOverflow社区EG. I am trying to export still images from a video file. I did it correctly.

Now i want to change average frame rate. That is if my video is 24fps and i want to export still images with 30fps. Now instead of 24 frames I need 30 frames.

Cany you please help me what to do.

Thanks in advance wizards

Use the -r command line option to FFmpeg to specify the output frame rate e.g.

ffmpeg -i input.mp4 -r 30 output.mp4

See the FFmpeg documentation here.
