[FFmpeg-user] newbie in trouble

Tue Jun 9 01:35:55 EEST 2020

I have ~3k images of about 2.3 megs each, all jpgs. I want to make a
video using them. I very seldom use ffmpeg so I always forget the
settings. I found a command line on stackexchange that seemed as if it
would do the job. Output is below.

I perhaps naively thought that 3k input frames would produce the same
number of output frames and then at 30fps playback I'd have 100 seconds
of video. That would be fine. 

What I did was wait a really long time while ffmpeg displayed a frame
count in excess of 10K, almost 20K and turned out a video clip of 112
megs. This doesn't seem reasonable. Can anyone who is able to interpret
the output below make a suggestion? I only want a simple video. The max
number of frames would be 16,000 - a day's worth at one every 5
seconds. I thought that many frames would make a 10 minute video which
is okay.

Ideas? 

Thanks,

Dave
