Professional :: Audio Import Changes Speed - Out Of Sync With Picture
Feb 21, 2011
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.
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.
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'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.
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 ..
When I use the webcam and microsoft to record a video, my audio and video are out of sync.This does not happens when I use the built-in Microphone on the webcam.
I am streaming live content via flv but the video is lagging audio by some time. I am using netstream and video but cannot find a way to set the FPS for the video, I think i could fix it if I knew how to adjust the FPS
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 am calling some streaming video on frames 1-11 to play for a multiple choice game. My video and audio are out of sync at times on frames 3-11? [code]...
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?
Following this tutorial: http:[url].....But I keep getting this error message:1046: Type was not found or was not a compile-time constant: CuePointEvent.
how to sync to mpr3 audio files at specific points?
I want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.
Is there a way to change the speed of audio/video playing in VideoPlayer or any other such control?Let's say to play voice recordings of slow speaking persons faster to save time.Some mp3 players (e.g. COWON S9) can keep the pitch to avoid funny voice.
As the game develops, it will speed up and I would like to speed the music up as well, is this possible using only one music clip and action script or will I need a seperate clip for each different speed.
I've been involved in a webproject where text will be converted into speech. Then the text should be highlighted word by word as the audio is played in the browser.
i can draw with mouse all over stage..but when i import image (handball field) and drag picture on stage i can only draw beneath this picture..my question how can i reference in AS3 code to draw on that imported picture..i wanna do something like whiteboard for coaches so they can draw actions for game..
I'm trying to import a wav file of voices to stage for adding to an animated character I'm making, but it will only import to the library when I want to see it on the stage? It seems to work fine in the library but every time I try to drag it on (or do an import to stage command) it simply doesnt let me move it over! I've tried with a wav and an mp3 but to no avail!
We are using FMS3.5 for VOD streaming. It's spotted that when we are using Flash Player Version = WIN 10.0.42.34/10,0,45,2, it is encountered that the video picture is hang but audio keeps playing after our commercial break point. we will first pause the video content and then use the same object to play the instream ad. After that, the video is resume when instream ad complete.
