  • ffmpeg missing frames when generating video from images

    5 décembre 2011, par Eder

    I have been trying to generate a video from a set of images using ffmpeg. Everything seems to be working, but when I watch the video I notice that some of the images are missing. I checked the output from ffmpeg, and it seems that it processes all the source images. Has any of you experienced the same problem ? I'm using mp4 format and mpeg4 codec.

    Interestingly, if I use avi format, without specifying any codec, I can see those missing images correctly (although the video seems to be jumping from one image to the next quite irregularly). By the way, I have only 14 images, so I set a frame rate of 6. The mp4 video is smooth with these settings, but the avi is quite 'jumpy'.

    Thanks in advance.

  • Why images are combined (ffmpeg) ?

    27 novembre 2020, par Jin X

    I want to create video from images (one image per frame).

    


    ffmpeg -framerate 21.533 -i %d.bmp -i z.wav -r 21.533 -t 120 -map 0:v:0 -map 1:a:0 -c:v libx265 -c:a aac -b:a 128k z.mp4

    


    When I watch resulting video I see (at least at the end of video) that frames are combined with each other (2 images on each frame overlaps with different transparency ratio). I seems like when source and destination frame rate mismatch.

    


    I can remove -framerate and -r options but result will be the same (with 25 fps).

    


    What's the problem ?
How to fix it ?
