Here is the basic command line I use, which is just default options for everything, interpreting the frames as a 60 fps video:įfmpeg -start_number 00001 -framerate 60 -i "./%05d.jpg" -s 1920x1080 -aspect 16:9 out.mp4 Now with the files in the right order you can use ffmpeg. I'm not sure if the file list gets sorted similarly when you drag and drop.) (another caveat: This relies on the OS sorting the input files, and I normally do this from the command line. New=$(printf "%05d.jpg" "$a") # pad to length of 5 The files should already be in sequential alphabetical order, this just renumbers them):
Save this as seq.command and you should be able to drag and drop files into it from Finder (I HIGHLY recommend making a backup of your files first.
#Flickery lightroom install
One fairly easy way to install it on a Mac is with Homebrew (follow the instructions to install Homebrew and then brew install ffmpeg in Terminal.)įfmpeg requires the files to be in numeric sequence, so I use a little shell script for this. I make my videos with the ffmpeg command-line utility. Now you can shoot your timelapse.)īelow part: This is kind of technical but it might help. Power cycle camera and possibly snap a picture because now it's being weird about turning on while the mirror is flipped up. Remove camera battery so the camera doesn't get a chance to reset the F-stop.
#Flickery lightroom manual
(Ridiculously convoluted way to get this on a lens that doesn't have manual aperture controls: Set camera to Live View mode. DOF preview mode would probably do the trick, but my Nikon D3200 doesn't have that so I resorted to putting tape over the CPU contacts on the lens so the camera thinks it's a dumb non-CPU lens. The solution to this is to lock down the F-stop so it doesn't move between shots. This isn't as consistent as you might think - for individual photos it's a negligible difference but it's very obvious in a video. Every time the camera takes a frame it stops down the aperture, then opens it up again so you get full brightness through the viewfinder.
I don't have a fix for your existing pictures (but see below), but as someone who likes to take timelapses with their DSLR, I know why this happened: It's small variations in the lens aperture.
