Ffmpeg expects the numbering to start at 0 or in this example. Then ffmpeg will only process the first three and ignore the last file. If you have missing numbers you can use a glob pattern or rename all the remaining files to close the gap. The default framerate is 25 fps. This is a speed which creates the illusion of a smooth animation for most humans eyes. If you still want more frames per second then use the -framerate argument:. If you want to have a slideshow then you have to lower the input framerate. The following command will show each image 5 seconds long:.
You can make a slideshow with different duration for each picture, by using the zoompan filter. You can make a slideshow with crossfading between the pictures, by using a combination of the zoompan and framerate filters. This will extract 25 images per second from the file video. If there are more than frames then the last image will be overwritten with the remaining frames leaving only the last frame. The images width and height is taken from the video.
Usually ffmpeg has one input file and one output file, but when we want to create a video from a set of image then we have a set of input files. Likewise, when extracting images from a video file there is a set of output files. A filename pattern is a pseudo filename to describe a set of filenames.

Technically there is a fourth form: the single image form. But that is a trivial special case and will not be discussed further in this section.
Import image sequences
In words: the string image- followed by three digits followed by the string. The notation is so complex because it is designed to accommodate many different use cases. The ffmpeg developers borrowed the notation and stripped it down to just one use case: how many digits. That is why it may seem unnecessarily complex. The technical jargon for this is to "escape" the character. If the filenames are not numbered using digits or are otherwise not formated regularly then one can use the glob pattern. Note that this is not supported on Windows. Wikipedia has related information at glob programming.
There are more glob patterns. For example? But we will not go in to more details here. The interessted reader can read more in depth information in the wikipedia page about glob programming. It is necessary to place the glob pattern in quotes otherwise the shell will expand the glob before executing the command. Note that this command has a different meaning because now image-bar. If your animation consists of multiple clips, put each collection of images in its own folder and do the following steps separately.
It is important that all of the images are in sequential order by name.

Fortunately, most digital cameras automatically number the images. But if you are creating stop motion frames by hand, it is important to name your files in increasing numeric order; no need to worry if there are gaps. Every image in the folder will become a part of the stop motion video clip. Fortunately, this makes it really easy to add or remove images in the sequence--all you have to do is delete or move an image into the folder! In the window that opens, navigate to your newly created folder of still images and select the first image. Every other frame will load automatically and in the order specified in Step 1.
With the images loaded, you need to make a choice: what frame rate do you want your stop motion video to play at?
That is, how many images do you want to be displayed per second. The higher the frame rate, the smoother the animation will be. The slower the frame rate, the more jerky the animation will be.
Most video cameras record at 60 frames per second fps while a cinema film will run at 24 fps. Television is broadcasted at For stop motion animation, a frame rate of 15 frames per second is a good place to start and can then be adjusted upward or downward to get the desired smoothness.
The frame rate has one more important effect on your final stop motion animation: the speed. A faster frame rate will speed up the action while a slower frame rate can make things appear in slow motion. Fortunately, the speed is also decided by the number of images you have. Any time you change the frame rate or the images in the folder, you will have to start back at Step 2.
Once you've figured out your sequence and frame rate, the final step is to export from QuickTime Pro to a rendered video clip. From this menu, you have a variety of options but also a number of presets. Unless you know what you are doing, select a preset for how you plan to use your video. If you've made it this far you now know a simple way to create stop motion animation on your computer!
Once you understand the basics, you'll be able to branch out and start making some pretty great effects. All that was necessary to create the lasers themselves was to open the images in paint and draw a green glow before importing. You don't need any fancy software to create amazing stop motion video. Just get out, play around, and be creative!
As an aside, the one downside to this method of stop motion video is the requirement for QuickTime Pro. Almost every computer these days has the more limited QuickTime Player. But if you want to do more than just watch. Fortunately there are some other useful capabilities added when you upgrade to QuickTime Pro. It is extremely useful to have a quick way to cut off the beginning and end of a clips.

Ausyeda, have fun with it! It all depends on how long you want the video to be, and how smooth you want the animation. Feature films like Coraline that are completely stop motion are 24 frames per second. But you can probably get by with 10 or Meaning 3, - 4, for a 5 minute video. Second of all, I didn't realize how easy it was to make stop motion animation videos!

Wow, you have opened up a whole new world Cool article for a newbie like me in this stopic I started to think I should learn how to do stop motion vids on the better way.. Thanks for sharing :. Thanks for the comment, JCO! I checked out your videos and you're definitely off to a great start. I'll keep my eye out for some new stuff from you! Cool article.
