Making a Digital Stopmotion Film: The Process in a Nutshell

Written by Mike Brent

I thought it would be a good idea to put up a basic overview of the entire process from a beginner’s perspective, so newbies can get a good idea of what kind of software they’ll need and how to get started. This covers a few of the Frequently Asked Questions that tend to show up on the board regularly. The main focus of this article is on using a framegrabber in conjunction with a DV camcorder or webcam, which is probably the best/easiest way to get started in stopmotion. And I won’t be going into great detail... you’ll find other sections of the Newbie Guide that go into greater depth on some of these subjects... I’ll provide links to them when applicable. First I'll diagram the basic process as a simple visual guide, and then I'll elaborate in writing underneath:

1... Capture Frames using a framegrabber

2... Edit your footage and add any effects, titles, sound and music using standard video editing software

3... compress using video compression software

4... post it online or output to video

Capture Frames

This can be done using many different kinds of cameras. I won't go into detail here about all the aspects of different cameras. That's a very in-depth issue, which is largely covered in Chapter 6: Choosing a Camera for Stop-motion. Suffice to say that if you use a webcam or DV camcorder then you have the decided advantage of using one of the powerful Framegrabber programs that have revolutionized stopmotion in recent years. Of course you can still do your animation on a film camera, or now you even have the brand new option of using a Digital Still Camera to capture your frames in high def, for even better quality than the standard broadcast resolution. But in order to get Framegrabber functionality with either of those options, it's necessary to rig up a little security cam looking through the viewfinder, or you could go low-tech and just use a webcam alongside your main camera, just so you can check your animation using onion skinning and frame scrubbing. I'd like to mention here that for any beginner, by far the easiest and best method of doing stopmotion would be with a webcam or a DV (digital video) camcorder running through a framegrabber program. Check Lionel Ivan Orozco's awesome StopMotionWorks site for two related articles, How to Record/Film Stopmo and Stopmo Software (Framegrabbers). This article covers pretty much the same territory as Lio's How-To writeup.

This seems like the right point to add this. Some framegrabber programs have a rotoscoping function, which allows you to load pre-shot video. You might for instance be making a film with a stopmo animated creature interacting with live actors in a real location, or possibly in a stopmotion miniature set. What you can do is first shoot your live action sequences, carefully planned for adding in the creature animation, and load the footage into your rotoscope window. It will show up as a background image, and then you can set up your animation scene and see your creature puppet as a transparent overlay against the live footage. But let me state.... a framegrabber program will not do the compositing for you (except for StopMotionMaker Plus)... it will only serve as a valuable tool to allow you to set up and animate your puppet 'relating to' the live actors, to get eyelines right and see when a spear seems to be making contact with rubber skin etc. You then need to use some kind of compositing software to actually composite the two pieces of footage together. After Effects will do compositing, as well as several other programs (which I don't know the name of). If you're a Mac user Stupendous Software has some inexpensive plug-ins that will turn iMovie into a decent compositor.

Also, if you're doing lip sync or shooting a music video where the puppets need to move in relation to the music, standard operating procedure is to first record either your dialogue or the music track, and then do the animation afterwards to match up to it. Magpie Pro is a program designed for creating exposure sheets (X sheets or Dope sheets) by breaking down dialogue into a frame-by-frame progression, showing what vowel or consonant sound is needed for each frame. You then use this information to create an exposure sheet that directs your animation. Matching music isn't quite as involved. You just need to use a program that will show you a music track on a scale.... you can set it to whatever frame rate you want to animate at (ex. 24 frames per second; standard film speed, or 29.97 fps, which is NTSC video running speed). This will then show you where the beats and the big sounds are in the music. Magpie Pro will do this, or you can use any number of music programs, such as Cubase LE. You would then use the information to make your X sheet.


Edit your footage

A framegrabber program is only for capturing your animation, not for editing it. For that you need to use standard, good-old editing software. Each computer platform has its own freebies available that will do a great job.... for PC's there's Windows Movie Maker and for Macs there's iMovie. If you don't already have this software pre-installed, then you can go to either Microsoft or Apple and download it for free. In even the simplest editing programs you can easily cut your scenes, remove any bad frames, speed things up or slow them down, move scenes around, add titles, sound
effects or music, and sometimes even special effects. And there are plug-in programs that can really maximize your editing software's capabilities, for instance Stupendous Software can turn iMovie into what I call a "poor-man's After Effects". I'm a Mac user, and I apologize for my lack of knowledge in the PC arena, but (and this is some of the most important newbie information you can ever possibly learn!) you can always search the web for relevant information and websites. Learning how to use a search engine is one of the greatest skills you can possess in any field. The internet brings all the world's knowledge right to your fingertips, and the only limiting factor is your own diligence and search-engine skills. For example, a Google search for Editor will dig up loads of info about people who edit stories, while free DV editor will show you exactly what you're looking for. Another great use of a search engine is to find online tutorials. Example; iMovie editing tutorial or bluescreen compositing tutorial.

There are also higher-end, more expensive editing and effects programs that will do a much better job, and generally require extensive training (can be self-taught through studying manuals and experimenting). After Effects is a popular (but not cheap or easy program for adding all kinds of special effects.


Compress

When you finish editing and adding titles etc, you'll end up with a huge uncompressed video file, several hundred megabytes. This is too big for posting on a website, or even to play smoothly on your computer. You need to compress it, to different degrees depending on what your final target is. If you're creating a DVD you'd need to use DVD Authoring software and actually lay out the menu and the chapters(if any... generally a short film doesn't use chapters) and the software will do the compression in Mpeg-2. For a VCD (video CD) you need to compress it to under 700 megs, and for posting on a website the idea is to get it as small as possible so people don't have to wait all day to download it. Quicktime Pro is a good compressor, and puts out .MOV files that are compatible with both PCs and Macs, and don't require special software to watch (such as Real player or an Xvid codec). Most people won't go download software just to watch one movie, and it's important that they not encounter any problems trying to watch your film, or most likely they'll just give up and you'll never hear from them. That's why we at StopMoShorts settled on using Sorensen 3 for compression... it does a fantastic job of creating very small files that look good - none of the annoying blockiness or weird shifting you can get with some codecs (notably AVIs) and has universal cross-platform compatibility. When I finish a film, even just a test, I'll always render out a version compressed in either Sorensen3 or H.264 (proprietery Apple Mac codec, won't work on PC's)just for viewing on my own computer, since the uncompressed video will stutter and skip if you try to play it. For this purpose I'll set the compression slider to it's highest setting, making a file too big for posting on a website, but that still looks almost uncompressed and will play smoothly.

Check out Jason Gottleib's Quicktime Compression Tutorial and also there's Flicktips. We had a couple more tutorials posted over at StopMoShorts, but the sites seem to be down now, or the links are broken. At any rate, compression is an essential skill, and you'd do well to do some web searching and learn as much about it as you can if you plan on working with digital video to any extent.

In addition to the compression itself, there are a few other tricks to consider that can make video clips much easier for downloading. For one thing, you don't need to have ten seconds of empty blackness before the opening credits pop up, and the credits themselves should be abbreviated. If your movie is going to be seen on a DVD or projected on a theater screen, then there's no problem with this...but if people are waiting for a slow dial-up modem to download it, then it's a nice gesture to edit things down for their convenience. We often use just the first frame for a title, since they'll be looking at it for a long time while it downloads, and the last frame for credits, which will be displayed indefinitely when the movie is over. Other things that can help reduce the download size include reducing framerate. 15 FPS is a good speed, especially if you shot on 2's... no need to show each frame twice when you can just show them once and cut out the extras. Make the window smaller. 320X240 is a decent size, half fullscreen, and still big enough to see everything pretty well. Keep in mind that setting up video for online viewing is always a compromise... you can't get it pristine and fullscreen and still end up with a small filesize.
