Flash :: Professional - Audio Out Of Sync
Aug 14, 2011
I have an animation that I am exporting as either a .wav or .mov file then editing in different software but when I import the new file it is out of sync. That sounds confusing so I will explain. The project is a cartoon and a temp dialogue track was created before animation started. Then that temp track was used to animate over and do lip synching. Recently, actors have re-recorded the original temp dialogue track. So, I need to export the original dialogue track out of Flash, use an editor, in this case Final Cut Pro, and replace the dialogue then export that as an audio file and bring it back into Flash.
But it is always out of sync. I have even exported a .wav file from Flash then immediately re-imported it and put it on the timeline and it is already out of sync. And it is the exact same audio! I don't even know how that could be possible. Surely if you export a wav from Flash and then re-import it, it should be exactly the same.

I'm using Flash CS4 to animate hi-def music videos. It seems that I can't keep the audio to stay in sync for anything over 2 or 3 minutes.
- I'm working a stage at 1280x720 and 30 fps
- audio is streamed on a separate layer
- mp3 publish settings are: stereo 128kbs
Inside the FLA file everything syncs perfect, but when it's published, everything drifts in the SWF and in everything else I've tried.I've tried exporting image sequences and popping the sequences into premiere pro to match up with the original wave, and i've also put the swf file in a premiere pro project as well. Whether a SWF or an image sequence, it always lapses after 2 or 3 minutes.

We are creating a 30-track mixing desk to demonstrate our percussion instruments. Take a look at www.bellpercmixer.com. As you can probably hear, the audio is not properly syncing up.
The files should be exactly the same length (8 seconds) but they are mp3s so I don't know if the compression messes the length up as I know it adds the gap between the loop? More than likely, it is my lack of action script skill that has caused this problem... e.g. does each track need to be on a separate layer with a sync-track type thing? Here is an example of the script:

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 am trying to edit and mix sound effects and music for a FLASH animation in ProTools. After much trial and error I figured out how to make an accurate Quick Time of my FLASH file to spot sounds to in ProTools. The problem is when I import my audio into FLASH, it speeds up making it out of sync with the picture. I did several tests and it looks like for ever minute of ProTools the audio in FLASH speeds up 2 frames. Both programs are running at 24 FPS.
It is not a NTSC vs Flim speed issue. All other programs read my PT audio file correctly and show it to be the correct length with the SFX where I placed them. FLASH speeds it up, making my animation not time to the music and effects causing me to resync all my layers. How do I accurately export a sound file into an AIFF format and import it into FLASH without FLASH changing the speed? I have my audio set to Stream as it should be. After 3 minutes my audio is 8 frames (1/3 of a second) out of sync with the picture.

Because the player optimizes framerate, antialiasing etc dependent on the performance capabilities of the platform upon which it is running, it was nearly impossible to ensure animation syncronization w/ audio. If the audio were on the timeline you could set sync params to stream, but if the audio is loaded programically forget it .. well until AS3 ..The following code throttles the player framerate to lock step the animation to the audio .. not perfect but the principal works ..

I have a project that involves playing back a video clip within my swf movie. The video clip plays fine on its own, but when brought into flash the video and audio become out of sync and the movie quality suffers dramatically. I have tried embedding and streaming.

I have a voice over that I am trying to load, and sync with on screen animations. So when the narrator says something the animations back it up. However, when I embed the audio clip in the timeline, it makes my whole flash movie slow to a crawl, and everything gets out of sync anyway. When I load it externally using AS3 like this:
ActionScript Code:
var my_sound:VoiceOver = new VoiceOver();
var channel:SoundChannel = my_sound.play();
Everthing works great, but I don't know how to sync it with my movieClip that contains my animations. Is there a way to have the external audio sync with a movieClip on the timeline?

Are there issues with using attachSound to sync sound clips with Movie Clips? I currently am having this problem. I have all my sounds in a separate swf (sounds.swf), then I call the sounds like this:
Code:
gear1_btn.onRelease = function() {
logo.gear1.play();
sounds.gearssmfx.start();
}
I build the movieclips with the sound on the timeline, so that I know they sync up. Then I remove the sound from the movieclip, and actually play the sound with the AS above. The above AS should play the same in the browser, but doesn't. The problem is that the movieclip animations often run slower in the browser than they did within Flash. Is is possible that the movie is running at a slower FPS in the browser? I have noticed that it runs slightly slower in Firefox than IE. I'm currently using 32fps.
Here is my development : [URL]
Specifically, I'm having problems with the gears next to the letter "S" and "0", click on them to play.

We use a Flash component to allow a user on our web site to record from a Webcam on to our own Flash Media Server. The problem we are having is that the video in a 30 second FLV freezes at the 7th second but the audio continues. The video unfreezes after a couple of seconds but never catches up with the audio. At the very end there's a "Fast-forwarding" of video for the last few seconds so that at literally the last moment, everything's in sync. This happens for almost all of our recordings. Has anyone experienced this type of behavior?

I have a long timeline (5000+ frames) with cartoon animation and streaming dialogue sound on it. I've run into the dreaded audio sync problem. I found many discussions, peaking around 2005, but no solutions for this problem. I have a track of silence to ensure frame-dropping even between lines of dialogue. Prior to around 2000 frames the error is not noticeable.
My testing shows that playback is off by 2 frames per 1000 at 24fps. So at frame 10,000 the audio is out of sync with the graphics by 20 frames, nearly a second. This is predictable and reproducible on a variety of PCs and an iMac. I'm publishing to Flash 8 + AS2, but publishing to Flash 9 or Flash 10 don't make any difference at all.
I don't want to split this into multiple SWFs. Scenes don't help. Putting things into multiple movieclips would complicate my controls and our workflow. Just shifting the audio on the timeline is preferable to those solutions, but it makes maintenance difficult.

I created a Flash program that utilizes audio and text. The audio is located in an external folder and is loaded using .loadSound(). The text is located on the timeline and appears based on a certain time in the audio. I have a pre-loader that looks to ensure all of the external audio is loaded before the user can move onto the appropriate screen and the audio would play. This is using a combination of the .getBytesTotal and .getsBytesLoaded.
It works fine on Windows 7 but doesn't seem to be working one particular user's Windows XP on IE 7 (So it's not happen on all Windows XP). On a particular user's computer, the text is slow to load while the sounds loads pretty quickly leaving the text out of sync. After a few screens, the text will catch up with the audio.

I'm trying to record a stream from a webcam using FMS4 developer edition. The streams are recording on a linux box in .flv files. These files though have problems.
1 - The video quality is terrible. Fuzzy/blocky. Any kind of motion looks awful. Is there any way to improve this?
2 - The sound jumps/skips and goes out of time with the video.
As it is now this is useless. I am trying to make a system where a user records a short video from the camera and then I upload it to YouTube from my server. If you use Youtube's webcam page the video quality is quite acceptable and the audio is obviously in sync too, so they must know something I don't. [URL]..

I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?

Just like the subject states, I am indeed having frame rate problems importing video to Flash CS3. When I export a video from Premiere with the settings: 1280x720frame rate of 23.976using H264 or Animation (basically every codec produces the same results),"embed video on SWF and play in timeline" When I do this the file exports fine. Playing it in Quicktime works fine and the audio syncs up no problem. But when I import it into Flash using the same settings, for some reason the movie clip is now too fast in that the video does not match the audio and seems to be at more like 12 fps now (just a guestimate). The action of the video is over long before the audio even comes in.I have verified that the frame rate is correct in Flash so it's not that.
I've done this literally hundreds of times in the past and suddenly it does not work and I can not figure out why. I'm not even really using video, but actually artwork that I am putting together as an animatic for an animated piece so the video could not have been imported incorrectly or digitized wrong either.

I've got my head around bones now, which isn't too bad once you get used to it. I have ten minutes of dialog which I have created mouth movements for in Lipsync MX, these are imported as a swf and then placed within my character's Head MovieClip.
Problem is, IK insists on using MovieClips instead of graphics. This means that the lip sync doesn't stay in touch with the main timeline - it only stays in sync until the main timeline is paused or jumps to a different point.
Is there an established method which allows you to embed a lip sync symbol within part of an armature and ensure it keeps pace with the main timeline, or am I going to have to code it somehow?

I have made an animation. I have a layer where I put sounds that execute on certain frames. No script are involved. When I play the movie inside Flash, everything looks good and sounds are syncing. When I make a preview of the movie, some of the sounds are out of sync. I have no idea why, it's the first time I get this kind of problem. All sounds are set to event, but I have tried with stream as well and get the same result.

Recently i had a problem with my flash player after installing a Windows Update (not sure if its related). Movies played on sites like YouTube became out of sync and pixelated. Im not exactly sure how to explain this, so i uploaded a few pictures of the issue.
[URL] The sound is normal and the only thing affected if the video. If is there is any sudden movement in the video, it will distort the image. using v10.2 and am on Win7 x64. Viewing the video's in Firefox. I had the same issue on my older computer a while back using Vista x64 in both Firefox and IE. The problem on my older computer was resolved by simply restarting the computer. But this time that didnt work. I also tried uninstalling and reinstalling flash, and restarted multiple times

Any programs out there that will automatically lip sync your animations for Flash that are available for OS X. I've found a few out there, but they're for Windows. If not, does anyone have a simple trick to make it less time consuming? I used to mess around in Flash but it's been ages. I remember essentially making each character a movie? Or was it making the mouth a movie? It ended up being that on the timeline you would just press a button and the right mouth would come up. I bet that sounds mental. Just keep in mind my Flash knowledge is super limited.

I'm working on an animation where some guys sings and in order to make that look good, i need some good lip syncing. Since this is not short clips, but a whole song on 2-3 minutes, it's very hard for me to make the lip sync perfect because I have to replay from the beginning in order to hear the music. So question one is: Are there a way that I can play the movie in the middle and still hear the music? And so the second question is that I can barely see the sound waves in the Music layer, even though there's lots of music. Here's a picture of how big the sound waves are: And that's in the middle of the song! The problem is not that the music is too low, because it's quite high. So question number two is: Are there a way that I can make the soundwaves bigger in the music layer without affecting the music itself?

I've run into a bit of a problem using Adobe's CS3 flash program in terms of lip syncing... I can place the sound files in the timeline at whichever point I like and so forth, but I have no way to play them in such a way where I can adequately make lip syncs. It's hard to explain, but in flash MX I would merely click the timeline, drag the cursor along it, and it would play the sounds as it did the frames, one piece at a time. That way I could tell where the consonants were and therefore where to change my characters' lips. This is not the same as simply hitting "enter" and letting the sound play in its entirety.

I'm sure I'm missing somethin simple; but I have spent hours looking and trying ways to do the following. I have a movie clip A (which is manually set to frame 1 or 2 or 3) and I have a movie clip B that is played when a timer is triggered. I want to move clip A down a bit during the first half of clip B and then back up bit by bit to its original location in the second half. Along the way I want to change the frame showing in clip A. For the first sixth of clip B I want clip A at frame 1, For the second sixth of clip B I want clip A at frame 2. I know the length of clip B. So I can hard code tests for when to do things if I know what frame number clip B is in.
