Professional :: Syncing Audio With Animation?
Mar 24, 2012
I'm making an animation in flash CS5, and everything went well with it until a certain scene, which is no different than the other scenes in terms of animation/audio. In that scene, while one character is finishing his audio sentence, the next audio line already begins, screwing up the animation to audio sync in the animation from that point on. This doesn't make sense because the line that begins too early, isn't marked to play until a few seconds into the NEXT scene. Why is this happening? I tried so many things and it's really frustrating that nothing is working. I tried changing the lines from even, to stream, from mp3 to wav, making scenes longer at the end, but no matter what I do, the next audio line begins really early, messing up the entire audio to animation sync of the entire video from that point on.

I was wondering whether MP3s or WAVs would be better to avoid syncing issues. Also, what audio stream settings would be best?
I was also wondering if you can manually play the audio track by moving the play head over it. I've tried multiple times with multiple settings to no avail.

I have a Flash movie which is synched to an MP3 file by adding keyframes at the appropriate points to trigger actions.
In the *.fla file, and in an exported *.swf or *.exe Projector file the synching is retained perfectly. However, when I include the *.swf in an html file, the synching is lost. It would appear that either the MP3 file is playing at the right speed and the movie is lagging behind, or the movie is at the right speed and the MP3 is playing faster than it should.
I have matched the Audio Output stream to the MP3 file in the Publish Settings dialogue (both now 128kbps), but the drifting still occurs in an html page.
I am using Flash 8.0 on a PC running Windows XP Pro SP3. I have a quad-core Intel Xeon, and 4meg of RAM.

I've developed an application which uses a (dynamic) XML file to load in several files; a maximum of four MP3 files and a number of JPG files.When everything has finished loading, the user can press a "Play" button. The application could be described as a "mixer"; it's used to give online music lessons and to facilitate this, the sheet music is loaded (cut up into into several JPGs) which move horizontally on the screen like a marquee, while the music it represents begins playback. The music exists of several MP3s so that the user can mute (e.g.) the vocals or the drums, allowing him to focus on (e.g.) the guitar.
So what's going wrong, is that the audio files are not playing in sync. They are all pre-loaded so any delay between files shouldn't be sought in the files not being fully loaded yet. For initiating playback in the application, I'm using a simple function with a for loop in it, which sets each instance of my sound class to start playing at position 0 of its timeline (I've added in highlighting for all of the "code" blocks in my post, to keep everything easy to read through):
Code:
function playSounds():void {
for (var iCnt:Number = 0; iCnt < aSound.length; iCnt++) {
// Start playback for each sound, at the time position set in the
[code]....
Seeing as this didn't work, I have no clue what I could give a shot next... so if anyone has any ideas or suggestions, it would be greatly appreciated! Something else I noticed, was that if I run the application on very fast PCs, the MP3s are almost always in sync, but the PC that I'm developing on isn't that sluggish either and they hardly ever run in sync on it - so it will form a problem for pretty much all of the people who will use the application.

Calling channel.position on an ENTER_FRAME event, I notice that it's not being updated every frame, but it looks more like every frame and a half.
var sound:Sound = new Sound(new URLRequest('music.mp3'));
var channel:SoundChannel = sound.play(); // assume the sound is completely,
// totally, 100% loaded

on animating a movieclip(s) based on a sound stream..
Basically - something like a spectrum analyzer or a visualization effect for a media player..
It doesn't have to be complex - as the basics are all i'm looking for so that I can expand upon that to fulfill my own agenda
Also - the sound is going to be dynamic, being that the user will specify a file to play, so this can't be done with simple frame animation (unless I were to create ~16,000 different swf files.. .. . . Yea)

I am using Flash CS3 on a PC. I am trying to export an animation to quicktime (Export > Export movie) and have some problem regarding the sound. The animation contains actionscript 2.0loads external swf contains streaming soundsplay other sounds via actionscript. 4 scenes. When publishing the animation, it works fine, but when exporting it to .mov, the audio goes faster than the video.
Export setting:
Video:Compression type: H.264Frame Rate: CurrentKeyFrames: 4
Sound:Compressor: 24-bit integerRate: 48.000KhzSize: 16BitUse: Stereo
To be honest, I tried many other compression types and frame rates and keyframes, but nothing seem to work.
I tried:
- importing the external swfs into the original animation
- creating a streaming silence from frame 1 for continuous sound
- capturing the animation using CamStudio, but it's not smooth enough

I'm having problems with many files losing their assets from the timeline after a save and reopening the file in Mac OS X Snow Leopard. This is happens quite often now and there seems to be no pattern to it. For example, I will open an existing Flash animation complete with sound and artwork, make changes to the animation timing, test the SWF and everything looks good, then save. After reopening the exact same file, there will be audio that was on the timeline will be an empty frame. In addition, there is art work that was swapped out or updated to a character and the symbols becomes empty after reopening.

I am doing a project on an interactive website that contains flash animations. I have to incorporate a voice that explains what is happening in the animations. I am using my own voice for this. I have recorded my voice and saved it as .mp3 files. between each animation there are about 6-10 audio files. I am pretty sure I can import the sounds into the flash library and drag the sounds on the timeline and sync the sound with the animations that way but is it possible to control the sound using actionscript as I have to incorporate buttons that allows the user to play, pause and stop the animation and the audio. Or can I only use actionscript to achieve this.

FrameSync is a free Flash extension, originally released nearly 2 years ago, that allows you rapidly lip-sync your characters with an audio track. Version 2.0 allows you sync your characters even faster and easier than before. ew features include a keyframe mode, audio playback and frame navigation for Flash CS5, and performance improvements. See this post for more details.

I'm working on adding sound effects to a short animation. The first few sounds are syncing perfectly, however when I test the movie in Flash Player, at about the middle part of the animation, the sounds no longer sync; they play ahead of where they are supposed to. Testing the movie right in Flash, though, the sounds are fine. Exporting to a SWF file as well as a MPEG-4 also plays the unsynched sounds where they are not supposed to be

The images for animation load okay. The sound loads okay. But the animation images need to be inserted in coordination with the sounds, which is difficult using only the ears, but I do not know how to keep the audio graph seen on the timeline so as to know where to put the images. I can keep the graph open on the little library window when it is open but not on the timeline. how to keep the graph open on the audio track while I work on the image tracks.

I'm learning AS3 as I modernize the VCR controls for our e-learning topics. The way we used to do it was load the wav into the timeline and keyframe to the audio. We have a little tracker bar you can click on to jump around, a tracker icon you can drag, play/pause and FF/RW buttons. In AS2, since the wav was in the timeline, I just had to worry about frame numbers.
It seems like the modern way to do it is to load the audio as an MP3 externally. How accurate will this be as far as sync'ing the audio to the animation when using the tracker bar and jumping around? I'll basically be mathematically slicing the bar graphic into pieces and using that to tell the animation what frame to start on, and converting that to a time for the audio to start.

I have a few animations that run on different scenes each time a scene is loaded the external audio should start with it. Well here is the thing the animation always starts before my audio files and each scene gets bugged. I need to create an action that only allows my scene to start with the audio and also starts loading the next audio so it wont be dellayed.
On the first scene I have the following code:
scene 1 frame 1
var autoPlay:Boolean;
if(!autoPlay){
stop();}
scene 1 frame 2 animation starts and audio 1 loads
import flash.media.Sound;
[Code] .....

ok lets say you create a button that when held down play an animation of 20 frames if realsed it goes to frame one and stops if held down it plays out this animation. for the topic lets say you have a fire animation and you want the fire to apear and if the user hold its down the animation reaches the end of the time line and loops back and plays the last 5 frames of the animation and as soon as it is let go it goes to and stops at frame one. Well i know how to make a button that when held down plays out an animation. And i know how to say when released goes to and stops at frame one. What i dont know how to do is to loop the fire at the last 5 or 6 frames so the user can hold it down all day long and play out that animation.

I have a certain set of motion twains that I've successfuly completed, they constantly loop right now (default), and is saved in the SWF file.I'd like to take that finished looping animation, and insert it within another animation (a) that can be played with a play button, and stopped/resetted with a stop button.How do I insert the completed looping animation into the main animation? And is there something special I have to do in the actionscript of the start and stop buttons so that the "inner" looping animation will start and stop with the "outer" main animation?

On a horizontal bar, text scrolls from left to right, continuously. The text is a fixed string of city names, and I've made it so that it loops nicely. This horizontal bar with scrolling text is part of a vertical animation, scrolling the bar in and out of view. The vertical tween starts after two seconds. When the vertical tween starts, the horizontal animation has started as well. At the beginning and end of the vertical tween, the horizontal tween starts over. I want it to continu.

We developed one application in which a user can chat with a customer. But FLV size of user is double than that of customer FLV. At the time of playing we are getting problem of sync issue between FLV files. We are setting buffer size of 10 seconds. Is their any other way so that we can sync both FLV and an officer can view the communication of user and customer. Is DVR will do in sync? If yes then how?

FLASH CS5
AS3
I would like to sync my sound file with the text on the timeline. This would amount to sound being played and the text changing color when that word is read. I have tried this manually in earlier versions of flash. I timed up the sound file with the text/color. Using this method the results were spotty and not always the same. Sometimes, depending on the computer, it was timed perfectly, others it was a second or so off.
Is there an easier way to accomplish sound to text syncing?
1) Using Flash CS5?
2) Using After Affects? - I thought about using AA because I can control the sound better. But I would prefer to use Flash.
3) Another program?

problem - syncing some background music with a movieclip. I am aware that you can place a sound directly onto the timeline of a movieclip: this was my first attempt at syncing the two up. Unfortunately the problem with this is that the sound (which is quite long) then won't STOP until it finishes playing regardless of whether I stop the movieclip or remove it from the stage. I also have no control over the volume this way.The only other method I can come up with involves keeping track of the current frame of the mc and triggering the sound manually, but this still goes out of sync if too much is happening at once and the framerate drops.
