Hi, I'm looking for a "standard" animation format for distribution of a CD title containing linear 8 bit children's animation (at 480*360). I hate to bombard you with a grocery list of (6) questions, but I'm trying to get up to speed on .FLCs. Your help will be appreciated! 1. What is contained in the animation support libarary? 2. Have you found the .FLC format to be compatable with the vast majority of MPC II systems, including the "low end" ones? Other formats, such as Quicktime, are finicky with regard to display devices and/or drivers. 3. I have seen mention here of the .FLC format having a palette that is not compatable with Windows. Assuming one has control over the environment, including the abilty to preload a palette with all the colors in the .FLC, is there still a "palette flash" problem; I'm not sure exactly what you mean by "incompatible." Also, will the palette issue be resolved with your upcoming Windows product? 4. Can you recommend software packages that I can use to sync. .FLC animations with sound? 5. Does the .FLC format lend itself to being stepped through backward and forward so, given the proper controls, one can manipulate the animation in a similar way to Quicktime? and finally… 6. Not asking for any guarantees, but would you expect me to have a problem displaying .FLCs at 480*360 with concurrent sound on a low end MPC II? Thanks in advance for your help, Steve Siegel

Good questions – I would like some feedback from others on the answers. "1. What is contained in the animation support libarary?" Some manuals, header files, etc., which help you understand the structure of the FLC and FLI files. Also, there is info for Visual Basic and C programmers for creating Windows players for Flic files. "2. Have you found the .FLC format to be compatable with the vast majority of MPC II systems?" Yes "3. I have seen mention here of the .FLC format having a palette that is not compatable with Windows." Of the 256 colors, you need to use a palette of 236. The first 10 and last 10 permit Windows to have palettes of its own without flashing. There may be some exceptions, but this is supposed to work. Also, will the palette issue be resolved with your upcoming Windows product?" The issue is bypassed; the Animator Studio products works in truecolor. You can save out to 256 or 236, etc. colors if you like. "4. Can you recommend software packages that I can use to sync. .FLC animations with sound?" Not really. Our player works if you keep the FLC files small enough so you don't lose synchronization. Check out MOVIE.ZIP (mentioned below) which assigns sounds to individual frames. You might find that AVI or Quicktime are good in this regard because the sound and image are linked. "5. Does the .FLC format lend itself to being stepped through backward and forward so, given the proper controls, one can manipulate the animation in a similar way to Quicktime?" Don't know about Quicktime. When I step backwards while playing a FLC file there is a moment's hesitation before it turns around. Perhaps saving a Flic backwards, then playing it forwards might avoid problems. "6. Not asking for any guarantees, but would you expect me to have a problem displaying .FLCs at 480*360 with concurrent sound on a low end MPC II?" Yes. No. Well, it depends on what the subject matter of the flic is! If you have a flic like an architectural walkthrough, every pixel on the screen is getting changed and the animation could be very sluggish. If you need to get around that, you might design your images to have a static background and as much as possible confine the animated portion to a small part, like a campfire, or a bird flying across the screen. Hope this helps.

Nik, Thanks very much for the quick response. I have a couple of follow-up questions: 1. Does the .FLC file format use rectangle differencing, or is the entire screen refreshed for every frame? And if the entire screen is refreshed, are there methods that exist for optimizing playback? (Or, is this somehow an irrelevant question with regard to flics?) 2. When I asked in my previous message about software packages for synchronizing sound with .FLCs, I did not mean in a lock-step nature, as in VFW or QT. What I'm looking for are packages that will allow me to display a flic on my screen along with a wave file, and edit them together so that when I launch the .FLC and .WAV concurrently, for short animations, they are more-or-less synchronized. Since I've read that .FLCs can have associated sound, I'm assuming that there is commercial software that will allow you create and synchronize animation and sound, much as Premiere provides this for QT and VFW.(If nothing available now, will Animator Studio do this?). The reason this is important to me, is that at this point, it seems that flics are a very viable format for CD titles. But coupling with sound is also necessary. Thanks, Steve

…associating flics and sound…. The flic format does not have sound associations, so you will have to do it with something like our Windows player, in the manner you described. Since it can be done, there must be applications other than ours that do this too. Animator Studio? I think that will not offer anything different in this regard. As far as "oes the .FLC file format use rectangle differencing, or is the entire screen refreshed for every frame?" I do not know the meaning of rectangle referencing. However, Flics are stored in a manner that sounds similar. The flic builds a pretty good picture of frame one, then with each successive frame records the changes from the preceding frame. So an animation with lots of foreground movement (like an architectural walkthrough) will have a larger file size as well as a harder time playing, than a flic with a similar number of frames that has a static background and very little movement.
