Question Recording Alice output as video file - 08-17-2005, 04:24 AM

To Alice developers:

Because of the number of avi and mov files on this site which are recordings of Alice sessions I thought the option to record the session was part of the program.

However, when I installed the program I found the option to save as a movie is not yet implemented

My interest in Alice is to use it to produce an animated cartoon series. Without this feature it is only of passing interest to me.

How did you do it?

I was able to get excellent recordings from Alice with hypercam. This is shareware, and you can get it for a trial period. Enjoy

G'day mate,

After my original post, I did a search of Shareware.com for screen recorders, and tried River Past Screen Recorder, which dropped frames, and locked up.

Hypercam didn't appear in the search results, but I'll look it up.

Default Alice Movie Making - 08-22-2005, 11:09 AM

The movie recording feature in Alice has been disabled for some time now as the videos it produced tended to be excessively large. As it stands, the team is looking at 3rd party software and will post a faq on how to install and run it sometime soon.

For the more adventuresome, here's the run down. Alice doesn't use the buffer on your video card so frame recording programs like Fraps won't work. However screen recording programs of the type used to create demos of the windows environment will. There are many options and it all depends on how much you are willing to pay for such a program and what kind of watermark you are willing to settle for if you are using the demo version.

A couple of weeks back I did a survey of possible screen recording programs. Hypercam was one of the many I looked at. However I settled on a different option as the one the Alice team would recommend.

Bulent's Screen Recorder has an unlimited trial period with a minor watermark. The program costs a mere $17.99 for those who want to pay for the full version. There is also a shareware version of it for those who ar
e willing to do a little bit of digging.

When using any screen recording software, I recommend using a click-to-start screen in your Alice world to give you more control over when your movie begins. An example of click-to-start can be found in the "Snow Love" demo that ships with Alice. Although using a black billboard is easier then dimming and raising the environmental lights as "Snow Love" does.

To record your movie you'll want to:
1) Run Alice and open the world you wish to record.
2) Under Edit->Preferences, click on the rendering tab. Under "render window position and size:" you will see a box next to width and height. Put in a reasonable value for the size of the video to be played. The larger the video the bigger the file will be. If the values aren't taking then resize the run window manually.
3) Click play to run your Alice program.
4) Open your screen recording software (the rest of the instructions assumes you are using Bulent's Screen Recorder although the process is similar with all screen recording packages).
5) Click the Select Source button and click on the "A Window" option. A dialogue box will appear with instructions. Move your mouse cursor over the window your Alice world is running in and hit Enter or F4.
6) Click on the Configuration button. The screen recorder window will expand to include a new frame. This panel will control the quality of the recording and conversely affect the size of the file that is generated.
7) Click the Compression button to open up a new window. The default for is to use the Microsoft Video 1 codex at 80% quality. That looks pretty bad. I recommend bumping the quality up to 100%. Click OK.

Note: Codex are the software algorithms used to encode videos. Each codex has varying strengths and weaknesses as they deal with the encoding process in different ways. The idea is to maintain a certain level of quality at the smallest possible file size. Raw or uncompressed video is the highest quality but eats up a lot of file space. It's a good option if you are planning on bringing the video into another program for further editing as there is no data loss from the initial grab. However the video needs to be compressed before it can be shared. One thing to remember about codex is that not everybody has the same codex you do. If you want to share your work to the largest audience it is best to pick a common codex even if it is not the most efficient compression.

Now you are ready to record your Alice video.

8) Restart your Alice world (if it has been running) or click on it to start, and press the camcorder button. Right below the Select Source button is red text that tells you what the program is doing. Confirm that it is recording (if it isn't search through the options to figure out why it's not recording. It may be waiting for you to press a key).

9) When the world has finished playing click on the stop button and press the play button to see your video. If you are satisfied, click on the save button to save it to your hard drive.

Other screen recording programs include Hypercam, Camtasia, My Screen Recorder and Quick Screen recorder. Try them out and find one that's right for you.

The Alice team is still looking at options for a 3rd party Mac screen recording program. If you find any that work well for you, post about it and we'll go through them.

Smile Codex? Codec. - 09-01-2005, 05:02 AM


Thanks for that Victoria. Just one minor thing...
A Codex is an ancient manuscript.
A Codec is an [en]COder/DEcoder.
Both of them are of interest to me, as codexes (codi?) form part of the topic of the Anime I want to produce.

How did you do it?
I've used Camtasia Studio (http://www.techsmith.com/camtasia.asp) to capture Alice playback and convert them into movies.

Studio does a decent job of converting it into flash. Though I have not tested, it will convert alice movies into about 10 other formats including quicktime.

The only problem is that you need to keep the screensize of your movie pretty small to prevent dropped frames if your movie is complicated.

Red face Capture Movie...maybe I'm a newbie - 08-18-2007, 07:17 AM

Sorry about the play with words but I am so severely frustrated with this movie capturing ordeal.

Thank you Victoria for your detailed answer. Unfortunately, I kept getting really low capture quality eg. worse clipping than the actual Alice movie and even worse sound synchro. I tried your suggested configurations at first. Then I tried fiddling with some of the options and taking the suggestion the programme gave when it told me that my capture quality was 0.9/10 ! Bad, yeah? Actually the best I got was 3.1/10 ! Bad, right?

I have a decent amount of music and sound, and also some quick movements in the 'movie' I'm trying to make.

Do I have any other options available? I'll be glad to try any other configurations you may suggest.

If you have the time, I'd appeciate the help.

My thanks go out to Victoria Webb for publishing the information identifying and explaining how to Bulient's Screen Recorder.

I have found a great need for the ability to create movies of lab projects so that the students can view them on their own schedule. I have just completed my first attempt to do this. You can view the results at

http://www.dickbaldwin.com/alice/Ali...tm#Lab_project

The biggest problem that I encountered was synchronizing the playing of the world with the recording so as to avoid long awkward pauses at the beginning and the end of the movie. You must be quick with the mouse to accomplish that.

So, I went looking for some free software that can be used to trim the pauses from the beginning the end. I discovered that, although somewhat tedious, this can be done using Windows Movie Maker, which is in Accessories in WinXP.

I will probably use the combination of these two programs to produce movies showing the execution of all the lab projects for use in my Programming Fundamentals class this semester.
