Choppy Video and Audio in Chrome after update to Yosemite

Anyone having the same issue as me? In Chrome my video and audio is choppy (play 1/2 second, pause, play again, etc). If I close Chrome (and quit all the way), and restart all is good for a few hours, then right back to the choppy playback (YouTube, Pandora, anything...). Only since updating to Yosemite. Any tips/suggestions?

I have this issue as well.
Only way I know to fix it is to CMD + Q and quit the Chrome process entirely. I'm a web developer so it's super awesome when I have to kill my 20 browser sessions just to fix this issue.
I have confirmed this issue happens in the HTML 5 video player as well as in Flash video.
NOTE: In the video below the audio/video skipping is part of the recording.

Video and audio STILL Stopping after 2 seconds

I am running Premiere Pro CS3 for Mac. For some reason, regardless of whether I capture direct fromDV cam or import a video or audio file. Occasionally (3 out of 5 times) the video and audio stops after 2 seconds. I hit space bar and it does it again. Ay ideas why?
I am running this on a brand new Mac Pro too.
Thanks,

Please provide
these details to help us help you.

Video and audio not linked after upgrade to cc

I recently upgraded from 5.5 to CC. Every project that I know open, the video and audio are no longer linked. I right click and enabled is checked. It's a huge pain when editing!!
Another starnge thing, after I reopen a project I'll notice that the audio tracks duplicated themselves??

You're welcome.

Super Slow / Choppy Video and Audio / ?

Hello Helpful Co-Users...
I am a fairly experienced film editor who has, in the last 2 years, begun working on small projects on iMovie. I am currently finishing up the third part of a three part project, and have come up to a problem I can't solve with any of the solutions I've already found on this forum: this 26-minute project is completely slowing my computer down beyond recognition. While the other two parts have, more or less, run fine (at 30:00 and 45:00) this project has recently begun to <really> slow the system down. Lags, choppiness, spinning wheel, the works.
I've done a clean re-install of 10.4.3, run Onyx, cleared iMovie bookmarks, cleared my QT Prefs, deleted preferences, run Disk Utility, done the 'Garage Band' trick I learned in this forum, and while these great tips have really got the machine working great otherwise, squeaky clean, this movie just kills.
Now, HERE's the rub: while the other two projects did use alot of CF/X crops, extracted audio, FX, and transitions, this one uses almost all cropped shots with of audio extraction (it's a sound-heavy piece, and I need reliable cross-fades, and there are lots of slowed down FX as well) that, I'm learning now, is possibly just too heavy of a burden for iMovie. It was working great, but then I just hit a wall. I wade around in the movie for awhile after a fresh restart, and then the wheel starts spinning, and the speed goes down to like
.1 megahertz. Ouch.
My question is: have I really hit the wall? Is there a chance that I have a corrupted clip that's slowing everything down (something that was hurting a previous project)? If so, how can I best find this corrupted clip?
Is there a way to render these clips, FX, crops and transitions–-while still working in iMovie–-to help it run faster?
Is there a way of salvaging this film, whether by importing it into FCP? Or should I just kill some of the not-completely-necessary audio extractions and re-render the clips?
I invite your comraderie and expertise...I have a feeling there's something I'm missing that 2 days of diligent searching can't get at...
Thanks so much: and thanks for all the solutions that previous posts have helped me to uncover...

Welcome to the forum, Brandon.
Unfortunately, I don't think anyone has discovered why this slowdown occurs. My guess is -- and it's only a guess -- that lots of extracted audio clips adds to the likelihood of it happening. If so, exporting the audio, then importing it should make the problem go away.
You would share the project to an AIFF sound file, then import that file back into the project and disable your other audio track. To export, choose File>Share>QuickTime > Expert Settings > Sound to AIFF.
Not ideal, for it makes the audio harder to edit. But if that's not an issue it might be a workaround.
This problem appears to be disk-related in some way. Sometimes moving the project to another disk solves the problem. Reformatting the disk has helped too.
http://discussions.apple.com/message.jspa?messageID=1329812#1329812
You've obviously covered the bases on this. If you discover something that works, please let us know.
This bug is long overdue for squashing.

Adobe premiere elements 13 - im getting choppy video and audio in premiere elements 13, how can i fix this...

what settings in preference and project settings can i set to fix this. i have a windows desktop

64 bit
intel core i5
2.8 ghz
8gb ram
i hav the software on my c drive and in scratch disks preferences i have the rest on my 2tb external drive same as project. thanx in advance...........

Thanks for the follow up. Sorry that the news was not better.
As for project settings (project preset)....that should be set to match the properties of the media that you import. Only one project preset per project, so, if you have more than one format, you need to set priorities for the project, and then work everything else around that prime choice. But, for now, assuming all the project content have the same format.
The program is set up to have the project select the project preset based on its analysis of the properties of the first source you drag to the Timeline. If it cannot do that for some reason, it does not give you the closest project preset for what you need, instead it gives you its default NTSC/AVCHD/Full HD 1080i30 or its PAL counterpart if you are working in a PAL setup. You can always check to see what the project set. See Edit Menu/Project Settings/General and the readings for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio (even if they look grayed out). You can view project settings there, but you cannot make significant changes in what has been set. So, you start a new project if the settings are not right.
The manual way for you to set the project preset....
File Menu/New/Project and Change Settings
In Change Settings, change the project preset to match the properties of your source file. OK out of there.
In the New Project dialog that you see next, change the name of the project, and make sure to have a check mark next to Force Selected Project Settings On This Project. OK out of there.
Back in the Expert workspace, import your source media using the project's Add Media/Files and Folders.
If you setup according to my suggestions in post 3 and are still have previewing issues, then I think we should look deeper into the video card/graphics card. See Device Manager/Display Adapters to verify what your computer is using. And, then go to the web site of the manufacturer of that card to determine if you have the latest driver for that card.
Please consider.
Thank you.

Video and audio not synchrone with apple tv after update mountian lion on macbook pro

i have a problem with my apple tv. after i bought and instaled mountain lion on my mac book pro i have trouble with apple tv and my laptop. when my laptop conects with apple tv most of the time my wifi doesnt work on my macbook but on my apple tv it stil does work. when it does work and i play a movie of my own by using itunes the first second the video and audio is synchrone but after that audio is at normal speed but the video gets behind. and i am getting sick of it. does sumbody reconize the problem and can help me with this problem?????

Same issue here- I can airplay my amazon prime library just fine from my iphone 5 but on my macbook- (mavericks, 15 inch 2013 retina with quad core i7, nvidia 650 M and SSD) it just sputters and lags.
I have noticed web video is considerably worse than local content, giving me pauses of up to 2 or 3 seconds in which video stops but audio continues in the amazon player. Youku video, however, seems relatively stable. Our subscription speed is 25 mbps, so that should be plenty to stream SD video from Amazon and doesn't account for why it would be nice and stable from the iphone, but not the mbp.
Playing light, locally hosted steam sidescrollers like Limbo is better but gives periodic drops in framerate on the Tv. when mirroring the framerate remains steady on the MBP screen.
Games airplayed from my iphone seem relatively stable, though with a noticably lower framerate on the TV than on the phone.
It seems these issues have abated considerably since yesterday's Apple TV update, but are still curious nonetheless and I'm not sure that the update yesterday was specifically meant to address those issues or if I'm just getting a time with less network interference now.
Comcast recently installed a new router/modem/phone combo, replacing our old separate modem and router setup. I'm going to test if putting the network on a different channel helps.

How do I get Video and Audio Chats with PCs ? iChat FAQ 3 (Updated 7/12/2008)
Applies to iChat 2.x, iChat 3.x and iChat 4.x to any version of AIM on a PC before AIM 6.1
This piece is designed for those trying to connect Mac to PC for Video and Audio chats. Any iChat version Panther and up.
Glossary For This FAQ
This bit is designed for clarity.
Video is the sending and /or recieving of pictures and sound.
Audio is the sending and or receiving of sound only.
One-Way is the ablity to start either an Audio or Video chat from one end to a receipient who can not match your capabilities (or Vice Versa)
What is needed
At the Mac end
A Mac running OS 10.3.x and iChat AV ver 2.1 or 10.4 plus iChat 3 or Leopard and iChat 4
A DSL/Cable/Fibre (Broadband) connection of at least an up link speed of 256kbs.
An AIM , @mac.com or MobileMe (@me.com) account name.
(hosting Multiple person Mac to Mac AV chats requires higher specs and broadband uplink speed).
At the PC end
1 PC running windows XP (home or Pro). THIS A MUST
The AIM Standalone Application, currently at ver. 5.9 at this link. AIM (the Site) now call this version Classic and it cannot be Installed On Vista
Note: there is also Trillian which has a Pro version for $25 that can also Video and Audio chat. The Basic version just Texts and Audio Chats (AIM does not Audio chat)
Some need the aimrtc12.exe file from Here Mostly Earlier than XP or Pre Service Pack 2 XP versions of Windows
Note: It has been noted that this file is now apparently included in Windows XP after Service Pack 2 and above.
An AIM account/screen name (AOL or Netscape count as well)
Service Pack 2 info. This info will allow the PC user to enable AIM thorough the XP Firewall. The Windows Firewall did not exist as such before this
Between both of you.
At least one camera (Mac end)
A sound input device (the camera, if it has one is ok)
Your Buddies screen/account name in each others Buddy Lists
Other tweaks
For some people, using AIM on a PC, may also have to make sure their preferences (properties) are set in the AIM Buddy list, for their camera and /or Mic. (Tuning at Message 570)
This is an icon button lower right on the Buddy List marked "Prefs" (AIM 5.5). This leads to the Preferences. Drop down the list until you read Live Video. Click on this. In the new window that opens click the button that says Tuning Video and Audio. Follow the instructions in the wizard that opens up. Access in AIM 5.9 for this is in the My AIM menu at the top of the Buddy list and then Options
To Start
You should now be able to chat to each other.
If each of you has a camera it can be full Video , as described in the Glossary at the top.
To start from the Mac end, select (highlight) your Buddy with one click. His camera icon should be dark. Click on the icon near his name or the one at the bottom of the Buddy List. (You do not have to start a text chat).
To start from the PC end you need to start a text chat, then select the Video icon at the bottom of the chat window.
If one of you has a camera and the other has a Mic then you will be able to chat One Way but have sound will be both ways.
To start this type of chat from the Mac end you will have to go to the menu item "Buddies" and drop down to the item "Invite to One Way Video Chat"
To start this from a PC follow the directions in the pargraph above. You may need to change the tab to the incoming Video at the back of the two to see the Video. These tabs are added when the Video chat starts and the front one normally states you do not have a camera and shows a connection to buy one.
It is also possible to chat One Way if the other person does not have a Mic: replies will have to be typed in a Text chat.
No Camera and No Mic will cause iChat to End the chat with "No Data Received for 10 Secs"
Summary
For any sort of sound to a PC using AIM, (Talk in PC or Audio in iChat) the Mac will need a camera. The other person can have a Mic and then live chats with sound both ways and Pictures (Video) the other.
NOTE: At This Time It Is NOT Possible to Audio (sound only) between Mac & PC with AIM & iChat
Trillian Basic can Audio. Trillian Pro can Video and has a bigger picture and can do Full Screen.
Another explanation of the set up can be found Here about AIM 5.5 but is transferable.
And Also here
My Web Pages particularly all of Page 12: What if your Girlfriend Lives a Long Way Away ? have more information.
I may receive some form of compensation, financial or otherwise, from my recommendation or link.

After years of owning all things Mac, I am finally trying to use iChat, and can't get it to work. I see my buddy, but all I can do is send a message--the video and audio chat icons are gray, as is inviting to a video chat under Buddies.

After years of owning all things Mac, I am finally trying to use iChat, and can't get it to work. I am using gmail, and I see my buddy (no camera icon next to her name), but all I can do is send a message--the video and audio chat icons are gray, as is inviting to a video chat under Buddies. My buddy has the same problem as I. We are able to do video chat through gmail, but I had hoped to use iChat. I am using OS 10.6.8, iChat v. 5.0.3. What am I missing?

HI,
iChat will Video chat to another iChat in a Jabber Buddy List (Google run a Jabber server for GoogleTalk)
However it will not Video to the Web Page login to iGoogle or the Web Mail Page login. (where people can Google Chat as it were in a Web Browser).
Nor does it video to the Google Talk Stand alone app for PCs or any other Jabber apps on any platform.
iChat uses a connection Process called SIP (Session Initiation Protocol) which is also used by other VoIP devices.
Jabber/XMPP invited the Jingle Protocol for Jabber Applications.
Google have included this in their Standalone app and the Plug-in for Web Browsers on both PCs and Mac (you can get this as a Standalone Plug-in or as part of Chrome)
More on this here This article has been changed several time in the recent months. It now claims a greater involvement by Google in writing the Jingle Library (Although now Google's version does not work with the others)
This tends to mean that using the web Login to Google to Chat also cannot video chat to other Jabber apps that are using Jingle.
If your Buddy is using iChat then check the Video Menu has two items to Enable Camera/Video chat and Microphone/Audio chats are ticked.
In the View Menu the Show Status Items should be ticked (Selecting them toggles the tick and the function On or Off)
It could be Internet speed but at this stage I would doubt this at this stage.

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

Video and audio (in one direction only) deteriorate after about 90 seconds

I begin a two-way video chat as normal, both parties can see and hear clearly. After about one and a half minutes of normal video chat, the person on the other end suddenly starts getting a highly pixelated image of me, and they start to lose chunks of audio from me. Meanwhile I continue to get a very nice clear video and audio from them. We usually end up closing the chat, because they are unable to hear or see me enough to continue.
The first 1.5 minutes or so is always clear, it starts after that. I always receive good audio and sound from the other party throughout the chat. I have never had problems receiving video/audio.
It happens with most (but not all) people I connect to. I am in California, and I always have this trouble when connecting to a relative in Connecticut. I have the problem again with one relative in Sydney Australia, but not with a different relative in Sydney. These are just a few examples by location.
I have repeatedly tested my connection speeds, and I have good up and down speeds - more than the minimum requirements. (My speed today is 8200 kb/s Down, 1309 kb/s up).
I have also tried:
Checking my Quicktime settings - (set to 1.5 Mbps T1/Intranet/LAN)
Bypassing my Airport modem/router, by connecting directly by ethernet to my Comcast cable modem (which has no router built in)
Replaced the cable modem with a brand new one.
Changed locations - tried it at a friend's house, still had the same problem.
So, I think I have isolated the problem to my PowerBook. This PowerBook used to do iChats really well for at least 18 months. I have been having this issue for about 5 or 6 months now. I have no idea what the problem could be. Any tips would be much appreciated.
Thanks, Martin
My setup:
ISP: Comcast Cable (Cable modem)
Apple Airport Exteme Base Station
Powerbook G4 1.67Ghz, 1 GB RAM, 80 GB HD
O/S: Tiger 10.4.10
iChat 3.1.8 (with Chax)
External iSight camera

With Comcast.
Try rebooting the Modem.
This seems to refresh the connection in some manner.
Also speak to them. They may not admit any connection management but thing may "magically" get better.

ITunes 11.02 update - video and audio no longer working

I updated to iTunes 11.02 last night.
Now, I can't play any video or any audio files, whether using iTunes or Quicktime. Even online Vimeo and YouTube content won't play. Clicking the play button does nothing - the movie or song's progress indicator doesn't move.
In Sytem Preferences > Sound: I get the following message for input and output devices "No input device found" and "No output device found"
There doesn't seem to be a way to check if the graphics card is recognised but it's still showing up in the system profiler.
Looks like the iTunes update has completely nixed my laptop's video and audio capabilities. Does anyone have any recommendations?

I do a lot of SONY HRD FX1 native 1080i HDV capture with Final Cut Pro 5 on my PowerBook 1.3 GHz G4..
Before Apple started supporting HDV, getting the audio and video lined up was such a nightmare that it wasn't even worth working on projects.
My material works great inside FCP 5, but I have had similar problems to what you describe when making the DVDs
However, I use DVD Studio Pro and was able to move the audio relative to the video slightly to get the most important parts to line up. However if your audio and video clips aren't the same length then you will have variable slippage for long clips.
I have been using MPEG Power Professional (Heuris Inc) to do my MPEG2 video encodes as well as my audio encodes and I haven't had the problem lately.

No picture etc. on TV.after connecting S video and audio cables fr.HP dv4305US and old Samsung

No picture coming from TV.after installing S video and audio cables from HP 4305 US to 6yrs.old Samsung TV.Much appreciate info on how to correct this.Do I have to have cable TV or a digital TV.converter?

Hi eb
Welcome to Apple Discussions
Could be a bad Dynex adapter, return that one for another and/or cough up the extra $3 for Apples.
I'm now using a Mini-DVD to to DVI and a 21.5 LG monitor, but my Apple Mini-DVI to Video adapter and my 27" Sharp served me well for a couple of years.
See the Tip in > http://support.apple.com/kb/TA23844?
+Tip: To make sure that your iMac automatically detects the external display or projector, be sure you plug the adapter into the external display or projector before you plug it into the iMac.+

Video and audio players will not show in Firefox. Players show in Safari and Chrome. (Mac computers). Do I need a plug-in?

Tested on 3 apple mac computers:
Mac Pro, Mini Mac and Macbook Pro.
Each computer running Mountain Lion and Firefox 11.8.800.94
Video and audio players not showing on website (video player is JWPlayer)
Error on video player placeholder says 'No video with supported format and MIME type found'
When the same site is access via either Chrome or Safari then the video and audio players show with all of the controls.

You get this error if the video tag is used and not an object or embed tag that specifies a Flash player.<br />
So this doesn't look like a problem with the Flash player as it is most likely not used in this case.<br />
If there is fall back code to use a Flash player then it isn't working.

Video and Audio not in sync after capture

Hi there,
This is probably a common problem, I have trawled the site but can't seem to find and explanation for it.
I'm capturing vide/audio into final cut pro from my SONY DVR. The video i have streaming into the sony DVR is from a small covert video device which records video/audio onto an SD card. SO I'm running that into the DVR and then DVR is outputting that as DV PAL firewire (uncontrollable device).
I'm capturing the 40 minutes of video as one clip, and when i drag it into the timeline the audio and video are WAY out of sync. Is there a simple reason for why this is happening?
It's almost as if not capturing it right.
I hope someone can help,
Thanks in advance.

It is interesting that you are having this problem. I recently purchased a brand new Mac Pro (a week ago) and I am using Premiere Pro and it is doing the exact same thing. I mean this video and audio is REALLy out of sync. I tried capturing an hour at a time, and 30 minutes at a time. Still, no luck. I was debating on getting Final Cut, but after reading this post I am rethinking not only Final Cut, but using Apple all together. Part of me thinks that it is not a Premiere or Final Cut problem but a Mac OS problem. But hey, what do I know. I only edit for a living.
