Aug 18, 2009We 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?

View 1 RepliesMedia Server :: Recording Webcam Video Quality/audio Sync?
Jan 21, 2011I'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]..

Mar 11, 2010Because 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 ..
View 1 RepliesFlash :: Professional - Audio Out Of Sync
Aug 14, 2011I 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.
Flash8 :: Controlling Embedded Video Audio?
Aug 19, 2010I am trying to control the audio of an embedded video from a mute button. I can get the audio to play and the mute button to control the volume using the following script:
var my_nc:NetConnection=new NetConnection();
my_nc.connect(null);
var my_ns:NetStream=new NetStream(my_nc);
[code]....
The problem I am having with this is that the video is not appearing on the stage and when I place it on the stage the audio is playing twice. how I can get it to appear on the stage and still control the sound as the button is doing at the moment?
Html :: Flash Audio Player For M4a (AAC) Audio File Embedded?
May 15, 2007I'm looking for a (free) flash player that I can embed in my site and use to play a .m4a (.mp4 with AAC audio) file that will be obtained using a URL (i.e. it's not local to the server hosting the web page).I've tried searching on google for one, but either I'm searching wrong or no one has made such a thing. Ideally this would be very simple (small user interface with play button and maybe a progress bar) and it would be easy to have multiple instances of on an html page (can create the player with an <object> tag).

Apr 11, 2010I'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.

View 1 RepliesMedia Server :: Play Multiple Videos In Sync?
Jul 20, 2011I need to build a website which shows multiple instruments in a band, being played in sync. Each camera/video block is a different instrument, and played together, they constitute an entire band. I have been searching high and low for ways to do this, and it definitely appears that HTML5 is out. It looks like standard FLV progressive download is out, too, because it's impossible to get 4-8 videos to sync perfectly.
I see on the FMS page that it has some abilities in synching. How would one (conceptually) go about making a webpage where say 4-8 videos begin to buffer, then when ready, play in sync? And they would also need to, when the location is changed, all sync to that location and rebuffer.
The objective is so that the user can mute/solo each video's audio, to remove an instrument(s) from the "mix" at any time.An alternative way of doing this, I think, would be to just put the 4-8 videos together in video editing, and encode this into one video, but have each video's audio track be a separate audio channel. If FMS can do multichannel audio on one video, this might work, if it could mix them in/out individually, as the user requires.
Css :: Flash :: Embedded Videos Be CSS Transformed?
Mar 11, 2011I'm experimenting with CSS transforms and I noticed that embedded videos (like for instances the ones from youtube) don't behave as expected when a CSS transformation is applied to them.
I've tested this in the latest Chrome, Firefox and IE and none of them was able to display transformed videos.Is this a bug of sort, or are videos not supposed to obey to CSS transformations? Not even using html5 in Chrome solved the issue.

View 2 RepliesProfessional :: Sync Up Audio In 30-track Mixer?
Mar 2, 2010We 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:

ActionScript 3.0 :: Sync Audio Loaded With MovieClip?
Jun 30, 2011I 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?
ActionScript 2.0 :: AttachSound - Sync Audio Clips With MC?
Jul 6, 2005Are 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.
Flash :: Professional - Sync And Frame Rate Importing Video To CS3
Oct 13, 2010Just 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.
Professional :: Export Animation To QuickTime - Audio Sync
Jun 18, 2010I 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
Professional :: Audio Import Changes Speed - Out Of Sync With Picture
Feb 21, 2011I 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.
IDE :: CS5 Audio Sync - Stream Sounds On Long Timeline?
May 13, 2011I 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.
ActionScript 2.0 :: External Audio Not In Sync With Text/screen On Windows XP?
Sep 23, 2011I 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.

Flash :: Flex Video Conference App - Audio Vs Video
Jul 12, 2011I am using Flex and FMS to develop a video conferencing application. I am using DynamicStream to automatically switch incoming streams to the appropriate bitrate depending on the available bandwidth. I was wondering if there is anyway in which I can instruct the DynamicStream to allow more bandwidth for audio (obviously at the cost of losing some frames from the video).
