Update: I watched the output video on a different machine and it was fine. The issue must've been with the program I was using to watch the video. Nevermind.

I'm trying to compress videos taken with my Canon camera for storage. Unfortunately, the output video has a decreased frame rate which makes the video not smooth. I've tried using -r 25 to increase the frame rate, but it doesn't make a difference. ffmpeg seems to ignore the option. Is there a way to force ffmpeg to use a higher quality variable frame rate or a constant frame rate? Do I need to use a different video codec? Do I need to use something other than ffmpeg? After much research, I haven't been able to make any progress. I can add a link to the input and output video if needed. Here's an example run:

H:\test>ffmpeg -i input.mov -c:v libx264 -crf 23 -r 25 -force_fps -c:a aac -stri

A sample (both input and output) would be good to have. I don't see anything wrong from the logs. –  slhck Jan 4 at 15:24
    
Do you really need to re-encode? Is storage space worth more than the time and energy it takes to re-encode and the loss of quality it introduces? If you want to encode faster then remove -r 25 -force_fps and use a faster encoding preset such as -preset ultrafast. See the FFmpeg and x264 Encoding Guide. –  LordNeckbeard Jan 4 at 19:46
    
Right now I have plenty of storage space, but I was just trying to think ahead in case I get low. I figured out the problem and have updated the question. Thanks for your help. –  Jacob O'Bryant Jan 6 at 4:43
