Re: [FFmpeg-user] Compressed file is larger than original...

I see there's more discussion but apart from the specifics of this instance it's a general rule that there will always be files that get larger for a compression attempt. If this were not so one could repeatedly compress a file to any arbitrary degree. Dave On Friday 25/06/2021 at 1:12

[FFmpeg-user] newbie in trouble

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

[FFmpeg-user] why is ffmpeg trying to overwrite an input file?

I have about 100 png files that are named with their creation date like this: '2019-10-18-204759_1366x768_scrot.png' . The collating sequence is the same as their chronological sequence. I found what seemed to be a reasonable suggestion to use: ffmpeg -framerate 24 -i *.png output.mp4 to make a

[FFmpeg-user] commonplace newbie question

I have a sequence of still that I make into a movie using ffmpeg. I'd like to use the GPU to speed the conversion but don't know if I can or how to do so. The images are 5 megapixel jpegs and the output is 30fps mp4. A thousand frames takes about an hour using my old Opteron 2210. In the
