I tried -framerate, but nothing happened. (Command line and complete, uncut console output missing.) ffmpeg -framerate 1/6 -i %03d.jpg -r 10 mom.mp4 (-r 10 is not strictly necessary but for example old vlc does not play files with very low framerates.) > > > The source .jpg images all vary in HxW size.

I slightly misunderstood the issue, the script would help if you wanted jpg's with the same height as output. Something similar to: ffmpeg -framerate 1/6 -i %03d.jpg -vf scale=-1:512 -r 10 mom.mp4 Carl Eugen ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Like I said, "newbie". I tried -framerate, but nothing happened. Then I tried -r. Do you have suggestions on how to get all of the images processed to the output and not just the first 3? > > > > Problem #2. > > > > The source .jpg images all vary in HxW size.

[FFmpeg-user] newbie help - framerate
I am trying for the first time to use ffmpeg. I have a collection of .jpg files starting at 000.jpg, numbered sequentially. On Windows 10 I've tried: ffmpeg.exe -start_number 000 -i %03d.jpg -r 1/6 mom.mp4 This works (images displayed for 10 seconds), but only shows 3 of the 300+ images. If I leave off the -r option it builds the .mp4 with all images, but they flash by as fast as possible. How do I get all images to show for 10 seconds? Problem #2. The source .jpg images all vary in HxW size. How do I get them all to display with the same height regardless of width? Thanks (I need this for a presentation on Monday - gulp!) --Mark ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
