Put Yourself in Your GoAnimate Video

Ever since the introduction of the the import video feature for GoPlus users of GoAnimate people have thought about the possibility of creating Roger Rabbit style animations, combining live action people with cartoon characters.

I first attempted this when the video import feature was introduced with my animation TET's PA Video Test. In that animation I simply overlaid cartoon elements and characters in front of the video. It worked reasonably well.

However to truly combine live action people with cartoon characters you need to be able to place the cartoon background and characters behind the live action video as well. To do that you need either a blue or green screen to combine the cartoon and video together in a technique known as chroma keying (more commonly referred to as 'green screen' or 'blue screen').

Watch my test video below to see my completed example using GoAnimate. Note that I recorded the video with a really short time frame to get it done so I pretty much just said some words off the top of my head.

Chroma keying is actually not that hard to do in theory. However the wider the live action area you want to film the harder it becomes to light the scene evenly. I'm getting ahead of myself though.

Before you do anything you'll need some video editing software that supports Chroma keying. I use Magic Movie Edit Pro 10 but the software is now up to version 17 and still very affordable at just US$59.99. It's great as an all round video editor too.

Next you'll need to grab a video camera and record some footage of your actor in front of a blue screen (or green screen, either colour will work fine. Just make sure your actor isn't wearing either blue or green unless you want them to be see through).

In the image below you can see my very, very, very make shift blue screen set up using a bed sheet and a bunch of desk lamps. You'll need this kind of set up if you want to film your actors entire body for your animation.



Note that this set up wasn't really adequate as the desk lamps weren't strong enough to light the screen evenly. Industrial halogen lights work best. When lighting your screen you need to set up your lights so they remove all shadows from your blue screen including the shadow cast by your actor. The lights on the screen should be behind where your actor is standing and angled towards the screen. What you're going for is an even shade of blue over the whole screen.

You will need at least one light to light your actor as the lights on the screen behind them will throw their face into shadow. Any lights on your actor need to be placed to the sides so that they don't cause a shadow to be cast on your blue screen.

If you only need to film a head and shoulders shot of your actor (as I did in the above animation) and you have a large plasma TV then the TV will make a great, evenly lit blue or green screen. This is what I used for my blue screen. I got the idea from youtuber, richw4. His instructional video is embeded below. He also shows you how to use the footage you record in Sony Vegas.



The beauty of this set up is that you don't need any lights for your screen as a TV is effectively just a big light bulb. However you may need an additional lamp or two to light your actors face - which I did. If this is the case then make sure you don't get any reflection from your additional lights in your TV screen.

When I finished filming my footage for my video it looked like this still from my video below - notice how evenly the blue colouring of the screen is. This is pretty much a perfectly lit blue screen.


Using your video editing software and the Chroma key effect you can easily replace all that blue with anything you like, a still image or even moving video etc.

For my video I simply took a snap shot of the Star Trek sick bay background. Imported that into my video editing software then rendered the combined video to a .wmv (Windows Media Video) file. I then uploaded that to GoAnimate and then overlaid the View screen and animated Spock on top of that in the studio.

If, for example, I wanted to have Doctor McCoy come up behind me in the sick bay I would have had to have made a separate animation of just Doctor McCoy in the sick bay walking towards the camera. I'd then have to download that video and import it into my video editing software to combine with my blue screen footage of me. I'd then render the combined footage of me with Doctor McCoy walking up from behind out to a .wmv file, upload that to GoAnimate... hopefully you get the idea.

It all sounds very complex but if you're prepared to do all the work you could make some pretty impressive animations that are bound to make people sit up and take notice - my test animation has received over 14,000 views to date and it's not even that great!

On a similar note, even if you don't have a big screen TV there's plenty of ways to improvise. Perhaps you don't want to film yourself or your friends to put in a video... what about filming toys and combining them with animation?

Below is a really rough video I made using my laptop computer as a green screen and a Lego Knight on a horse. I'll admit it's not perfect by any means but it does show that you can experiment with chroma keying with a bare minimum of equipment.

The Ultimate Independent Animator's App and Resource List 2019 - Animation and Video Life

Being an independent animator is not like a studio animation job. There's so much more to do that is indirectly related to the actual task of animating. Over the years I've sought out many apps, tools, and services that can help me achieve that one single task, expressing myself through animation.

Below is my Ultimate Independent Animator's Resource List for 2019. It started out as a list of free or low cost apps that could help you in every stage of producing either 2D or 3D animation, and then just kind of grew from there.

You may not have been looking for a Time Management App as much as you needed something to get you started in 3D animation but when those commissioned projects start coming in you'll have a head start on maximizing your time.

All the apps and services on this list had to meet two main criteria:

They had to be useful and relevant to an Indy Animator/artist.The base app/service had to be US$200.00 or less.
(In the case of a subscription service that&…

Eric W. Schwartz: Cartoonist, Animator and Amiga Die Hard

American Cartoonist, Eric W. Schwartz, (whose unofficial Amiga Icon, Amy the Squirrel, is pictured on the July 92 edition of CU Amiga cover on the right) is my only real animation hero. Sure there are the big names like Disney, Chuck Jones, Tex Avery and even Preston Blair whose influences can all be seen in my own cartoons but Eric did what none of the others could. He showed that really great 2D computer animation was within my reach with little more than an Amiga Computer, a copy of Deluxe Paint and Moviesetter.

This was at a time when computer based animation was in its infancy (outside of computer game animation) and Flash was something that lights did.

There were many great Amiga artists but Eric was really the only one consistently making very funny, traditional style animations. His humor and drawing style is heavily influenced by classic Warner Brothers and Disney cartoons but he managed to build on this, creating something that was recognizably Eric's own style.

I've…

Review: CrazyTalk Animator 3 vs Moho Studio Pro 12

Reallusion's CrazyTalk Animator 3 or Smith Micro's Moho Studio Pro 12. Which of these 2D animation applications is right for you?

Regular readers of this blog will know I'm a strong supporter, and fairly proficient user of CrazyTalk Animator since version 1. It's a great piece of software for producing 2D animations from purchased content quickly and, with version 3, is easier than ever to create animations from your own art.

Lesser known is that I first purchased Moho Studio Pro 12 (then known as Anime Studio Pro 9) back in October of 2012 and have been upgrading it to the latest version ever since because I believed in it as an application for creating great 2D animation to TV quality standard. As such, it's a much more complex application than CTA3 that I only got around to learning properly late last year. I'm still in the process of blogging my progress.

Despite this I feel I've learned enough of Moho to compare it to CTA3 to help you determine which …

Review: Renderforest Whiteboard Animation Toolkit - Fast Cloud Animated Video

For a while Whiteboard Animation became a thing, particularly when the YouTube meme Draw My Life started to circulate.

Though, technically drawing on a whiteboard isn't animation any online video employing that style of technique is usually referred to as Whiteboard Animation.

The popularity of Whiteboard Animation saw the process of creating them become automated with simulated whiteboard animation. In a simulation a still, photographic image of a hand holding a marker, is moved around an image as it is 'drawn' on a usually white background.

Generally, if the image being drawn looks hand drawn, and the hand actually follows the lines as they are being drawn it looks almost as interesting as an actual real hand drawing on a whiteboard. However the illusion can be ruined if the hand is speed drawing perfectly formed lettering in a non hand drawn font, or worse is speed drawing photographs.

Renderforest's Whiteboard Animation Toolkit is one such simulator that I thought…

Learn Moho Pro 12 Free Using SmithMicro's Own 104 Video Tutorials Sorted into a Logical Order of Progression

So you've bought Smith Micro's Moho Pro 12 along with the Moho, 10 hour, 104 Video Tutorials Add On pack so you can get learning right away... only you can't. For whatever reason, the video tutorials aren't sorted into any logical order of progression making them hard to follow.

Yeah, I've been there, only I've done what Smith Micro should have done and sorted all the video tutorials into a logical order of natural progression for you. That is, each tutorial builds upon what you learned in previous videos and you won't suddenly come up against some feature you've never used before, unless that feature is what the video tutorial is about.

Voice All Your Own Animated Characters with Voice Changer

Voice Changer by AVSoft is real time voice manipulation software that can be used for a wide range of purposes including (according to their website); Voice-over and voice dubbing for audio/video clips, presentations, narrations, voice messages, voice mails, E-greeting cards, broadcasting, etc.; mimic the voice of any person, create animal sounds, change/replace/remove voices in songs, videos,etc.

I bought it for the specific purpose of changing my own voice, to extend my vocal range, for voicing characters in my own animations.
I was fortunate enough to get this software at a significant discount that made it difficult to refuse, given that I'd never tried it, or even heard of it before. I'm not sure if I would have bought it at the full price given that much of what it can do (for my needs) can also be done with the freeware audio program, Audacity.
Voice Changer is relatively easy to install and set up. Once installed simply change you default microphone to the installed AV…

Tutorial: Lip Syncing Hands with Cartoon Animator 4

Most people accentuate almost everything they say with their hands, if they aren't consciously making an effort to keep their hands still, such as TV presenters often do.

Generally the more excited we are the more expressive our hands become. If we're really excited we might wave our hands in the air for example.

At other times our hands may reinforce a mood with actions that support our feelings, maybe if you're really sad you might rest your head in your hands, or wipe away tears.

In animation your characters can really seem more alive if you pay attention to what their hands are doing as they speak, creating gestures that support their dialogue. In other words, lip syncing your character's hands with what they are saying.

Unfortunately there's no auto hand syncing function in Cartoon Animator 4 but getting your characters hands talking doesn't have to be painstakingly laborious. You don't need to key frame every action if you take advantage of predefine…
