Video and Audio no longer line up

I don't know if this question would be better placed on the iDVD board but I've had a lot of luck with my questions here so I thought I'd give it a shot here first.
I'm working on a FCP Native HDV project and I spent a lot of time lining up certain spots in the video with the audio track (which is an aiff song file). Everything plays perfect in FCP. I exported as a Quicktime reference movie (the top export option) and brought the file into iDVD. After iDVD encoded the video, the audio and video are no longer quite in sync (I noticed this when previewing through iDVD and after saving as a disc image, mounting, and playing back with DVD Player). I think they start out in sync and go slightly off (the audio gets slightly, maybe a 1 or 2 frames, behind the video). I'm guessing this issue is happening in iDVD's conversion process and I was wondering if there is any way to fix this. Anyone had similar issues? Thanks everyone.
PowerBook G4 Mac OS X (10.4.4) 1.67 GHz PowerPC, 1 GB RAM

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.

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?

Video and audio do not line

I have a zen vision:m 60 GB. when i use the conversion program to put video on the zen the sound does not match up with the video. the sound is atleast a second behind the video, i have all the lastest downloads and every thing. what is wrong with the zen converter? does any one else have this problem and how can i fix it. i have also tried this on 3 differnet computers, i get the same results. if it cannot be fixed can you recommend a good free video converter that will work with my zen.

What kind of file are you trying to covert?

Simultaneous import of video via firewire and audio via in-line audio port

I have a converter that takes the S-video and audio input from my DVR then converts both to DV format, and then outputs via firewire. I hook the firewire up to my G5, open iMovieHD, and the application recognizes that as a camera and imports wonderfully.
Well, the audio comes through with a MAJOR buzz or hum. It's probably the converter, but the buzz/hum is not enjoyable.
So, I removed the audio from the converter, and the video converts wonderfully in iMovie without the audio. I have the audio coming in through my audio line-in.
I start to import my video, and iMovie starts recording the video. But I want to record the line-in audio at the same time. But when I switch to audio to turn on the input from the line-in, the video stops capturing.
When I start to capture audio first, then switch to capture video, then the audio stops capturing.
Is there any way that I can capture the video via firewire for one "track", and my line-in audio for the other "track", and have them play simultaneously in iMovie during capture??
Any help would be appreciated. thanks Adam

hey there badkitty 42,
i don't think you can do that. it sounds like your issue is electrical. try turning the plug around on each piece of gear in the chain & listen for the buzz. if it's not heard you've found the cause of your ground loop. you can also pick up some of the 3-prong orange or grey electrical adapters from Lowe's or Home Depot to see if you can "lift the ground" to get rid of the buzz. i'd try one on the convertor 1st. one last thing, do you have any flourescent lights in use on the same circuit or in proximity to where you're doing your transcoding? these are notorious for inducing 60Hz hum in audio & video gear.
good luck.

Video and audio out of synch after export

Hello guys,
I have 5 minutes long video on timeline.
1 audio and 3 video layers.
All looks good, but once I export it as QuickTime self contained movie (current settings) to my desktop, video and audio is out of synch.
Any ideas what it might be wrong?
Thank you for any advise.

Hi
Did You Render All - first - before Export
Did You Mixdown Audio - Render Only - last line
What material was used
• Video Codec and fps
• Audio file formats and bit-depth and frequency e.g. .aiff 48kHz 16-bit
• What kind of Project Set-Up did You use e.g. Easy Set-Up - PAL-48kHz

Video and audio not linking

Hello all:
I'm using FC 4.5 and for some reason the video and audio has decided to no longer link together... even though they are captured as merged files. The Stereo Pair and Link command under the Modify tab seem to have no effect (even though the clips indicate that they are - a line runs through them). Only recently started to occur. Real pain the in the buttocks. Any ideas out there?
Thanks

Delay in video and Audio

I use iChat to video chat with two friends in the UK. One is a o2 user and the other is a talktalk user. Wen chatting we experience an up to 7 seconds delay in voice and Video and audio. When we change to Skype there is no delay. Can you explain and solve this please. You do a great job Ralph. Thank you.

Hi,
Umm Bermuda.
Ok Start with.
If anyone is on 10.5.x then go to System Preferences > Quicktime > Streaming at set the drop down to 1.5Mbps and restart iChat (so it "Sees" the new speed)
On Snow Leopard and Leopard computers go to iChat > Preferences > Video Section and set the Bandwidth to 500kbps as a starting point.
If this in itself does nor sort the issue the slowest Buddy (Internet Connection) should drop their's to 200kbps - This is on the iChat Limit in a 3 or 4 way chat as the Specs say 384k
It is worth while having the Connection Doctor (Video Menu) open for this.
Also try changing who is Host.
Ideally it should be the one with the fastest Internet connection.
I have a vague feeling about Bermuda or one of the other small islands where the Local telephone company had become the default ISP - and in the day of iChat 3 where effectively blocking iChat by blocking the SIP Ports (Vonage and other VoIP adapters) that "lost" them Long Distance Telephone connection monies.
The thread about that was some time ago.
It maybe that they cannot support Video chats (Or lots of Off island Video Chats and On-line gaming) due to the ISP's own data rate to the "Main land".
Does it become apparent when you join the chat ?
Or does it not matter who hosts and who joins last ?

Working with Video and Audio...Please help (i am not a coder!)

Hey all. I am currently working on a project in Flash (CS3
action 2.0)
It is an animation and it includes a layer mask of a TV
screen, which shows a precut quicktime movie on the screen.
I am working with multiple scenes (11 to be exact) they are
all my different cut points.
The animation consists of 1st scene- VO (voice over) and BG
SFX. When I hit Apple+Enter this part plays sync'd up correctly.
However as the scenes progress on the sound gets out of whack.
Scene 2 consists of the quicktime movie (Video and Audio)
mask playing on the screen. All sound heard is a part of the .mov.
For this one the timing is also good.
Here is where it gets fluky. The next scene consists of a VO
and BG SFX. (and only those things) However, at this point of the
movie i hear the sound of the next .mov i have embedded in the file
(from scene 3). This is all happening well before that scene even
shows up in the preview.
I hope i explained it as clearly as possible. Anyone have any
ideas?! I would greatly appreciate it!
btw- i have set the frame rate to 29fps to match that of the
quicktime movies that are embedded.

Hi Brian, I don't mean to nit-pick but this is an
actionscript 3 forum, so you'd probably have better luck with the
general forum for non-AS3 questions.
There could be a couple of things that are causing a problem,
its hard to say without actually having your project on hand.
It almost sounds like your movie is taking longer to load, if
thats the case you could simply start the audio a little later in
the time line to sync it up.
I know you don't want coding solutions but you can probably
have flash "wait" for the movie to begin playing, and have that act
as the starting point for the audio.

With newer MacBook Air, sending both video and audio to an LG TV works fine, but I want to send the audio to a sound bar attached to the TV. Any way to do this?

I am trying to get audio to play through the soundbar attached to the TV for great sound. Works fine with Apple TV, but on the MacBook Air, system preferences will only find the TV speakers. If I change the settings on the TV to external speakers (the soundbar), then I get no sound at all. The HDMI connection does what it is supposed to do, providing video and audio, but the audio can only go to the TV. I don't know if you can go backward and send only video through HDMI and then connect to the soundbar through the mini jack ports on the computer and the soundbar. Any solutions will be appreciated.

its important to do this in the correct order so the camera will be senced by the Mac and to prevent the Firewire connection from electrical damage:
power down your Mac
connect firewire from camera to Mac
power on camera and insert tape in camera and play back
power up Mac
start QuickTime
File > Preferences > record tab
video source - select the camera you have
sound source - select the camera you have
quality - select device native
the video should show in the QuicTime window
a green line below video will show presence of sound-it will play through the speakers if they are selected in system prefernces
rewind tape and playback
click on red button to start recording

How can you use one NetStream to publish video and audio from another NetStream in AS3?

Let's say one of your client programs in AS3 is able to receive live video and audio from a NetStream and play it on the screen. How could you make it also take that video/audio stream that it's receiving, copy it over into another NetStream, and publish it elsewhere? I need to know how to do with this regardless of whether RTMP, RTMFP, or some mixture is involved. The reason why the stream needs to be relayed this way is a real long story, but it's necessary in this particular case. Thanks!

RTMP is TCP, which has higher overhead and latency because it guarantees packets are delivered (handshaking, causing latency and overhead). It also doesn't allow you to share connections directly between clients forcing the server to do all the work.
RTMFP uses UDP, which is a choice protocol for streaming video because it's the opposite. It's lossy which decreases latency and overhead from no retransmissions and most importantly (in some applications) allows you to connect directly from one Flash Player to another Flash Player (p2p) so the server overhead is dramatically reduced. The server is only required to negotiate the initial connection and then it's up to the clients to continue to facilitate that.
How you code your one to many or many to many relationship broadcast network will be based entirely on which of those you choose.
URLStream is very common to use in p2p. Here's an older Adobe article on p2p and an alternate quick old video tutorial (FP10) as a quick simple example of p2p over RTMFP you can view the source of.

How can i fix a clip when the video and audio are not matching up?

How can i fix a clip when the video and audio are not matching up? I imported the video from a junkdrive in a .VOB format and concerted to a .mov the videos were filmed on a miniDVD recorder.

I would try detaching the audio and the dragging the audio to the left or right until it lines up.

Recording Video and Audio at Same time with simultaneous sync

I want to record a keyboard performance into garageband and at the same time record the playing of that performance with my video camera. Then I want to create a movie using the music from garageband and the video from the camera. I was thinking that if I can sync the video and audio when I'm recording the session, then that part is taken care of. Or, maybe this is easier than I think it is?
Is there a way to do this so that I can use the garageband record performance and have it synced to the video on the camera?
I don't want to use the audio from the video camera because the performance that is captured in Garageband will be much better and I can do editing of the individual notes in GB.
In the end, I just want to make a movie and/or podcast of the performance.
I'm a newbie regarding this, but I did search the forums and couldn't find anything specific. Mostly it was about importing video into GB3 and then syncing new audio. I'll basically have audio and video from the same performance in two separate locations and I want to bring them together perfectly in Garageband.
Thanks for any help you can provide.

Okay. I got the video and audio all together. I told you I'd link to it when it was up.

There's also a copy of it at http://www.myspace.com/bonjimmy/
And as a quick side comment, even though I uploaded the same video to both YouTube and MySpace, the MySpace version is much better. YouTube must do something to the video after it's uploaded.
What I learned doing this project:
I recorded the video first (which gave me the sequencing of the piano performance) and then I dubbed the audio in later. However, there wasn't a good way to sync the video and the prerecorded piano, so there are some spots where the dubbed audio vocal isn't accurate to the video. I'm not sure what the pros do for this. I was hoping I'd remember how I sang for the video but when a couple weeks go by before re-doing the audio, it's about impossible. I tried, though.
I remember working with an old 4-track and smpte to a sequencer a long time ago. With the way it is now, it's pretty cool that you can record digitally and mix and match and everything falls together perfectly as long as you have a place to match the video and the audio. It's pretty cool.
What else???
Does anyone have suggestions that would have made it better? Also, if you have suggestions on my performance or whatever, I'd love comments, but you can do that on the linked page.
Thanks again for all your help. (The point of the video is because I'm thinking about getting back out there and doing some more playing... I'm looking for a band or something else interesting...)

Getting Ripped DVD Video and Audio Into Encore

Do you have previously authored DVDs that need rework? Do you want to add menus with greater impact and functionality? Do you want to add some additional program or supplemental material? Does a client want their product demo DVD to be updated to reflect the capabilities of the new and improved version, but the source files no longer exist? Using Adobe Encore DVD and a freeware utility called DVD Decrypter (DVDD), you can accomplish this quickly and easily.
Disclaimer: I do not support the illegal copying and/or distribution of copyrighted works. The authors and distributors of the software I use have made it clear that they do not support illegal copying. This guide is intended solely to assist you in ripping and copying DVD video to which you have the legal rights. Any use of this guide to infringe the copyright of someone else’s intellectual property is prohibited.
This guide is based on Adobe Encore DVD 1.5.1 and DVD Decrypter version 3.5.4.0. Let’s Begin!
Place the DVD to be ripped in your DVD drive and launch DVDD. If you have more than one drive (e.g., a DVD-ROM and a DVD burner) make sure the one with the disc is selected in the Source dropdown list in the main program window. Now we need to set up DVDD to extract video in a way that is “Encore friendly”. This is the toughest part of the whole exercise. Click on the Tools menu item and choose “Settings…”.
Settings
General Tab: You can leave these set at their defaults if you like. Personally, I specify a custom Default Destination. I put my ripped video assets all in one place anyway, and having a default destination means I have one less thing to do when I rip a DVD.
IFO Mode Tab: Make sure that “Select Main Movie PGC” and “Enable Stream Processing” are checked. “Uncheck Suspect Cells” is probably a good default safety check. If your hard disks are formatted as NTFS, set File Splitting to “None”. I leave “Copy IFO File” checked with the default sub-items checked. Make sure that “Patch M2V Timecode” is unchecked. The items in the Create Additional Files section are purely optional. The author of DVDD has been kind enough to list which programs need which files; notice that Encore DVD isn’t listed as needing any of these extra files. I do keep the “Stream Information” box checked. DVDD generates very informative file names, but I like to keep “Include PGC Number” under File Names checked. Be advised you will get some lengthy file names after DVDD is finished ripping.
Stream Processing Tab: Since we enabled stream processing in the IFO Mode tab, we need to tell DVDD how to process those streams. To save yourself time and confusion later, check the “Convert PCM to WAV” box. Earlier versions of Encore required a Demuxed audio stream and a Raw video stream. Encore 1.5.1 can accept either type of video stream (Raw or Demuxed) but it does still require a Demuxed audio stream. However, I still recommend using Raw video and Demuxed audio, if only because it seems to be somewhat faster to process in DVDD. This workflow is also backward-compatible with earlier versions of Encore.
So let’s set up the Stream Processing tab now. In the Demux box, enter “0x8? 0xA? 0xC?”. This ensures that all audio streams in the selected PGC, whether AC3, PCM or MPEG will be set to Demux. In the Raw box, enter “0xE0”. This ensures that the video from the selected PGC will be set to Raw.
Additional Notes about the Stream Processing Tab:
1. For those of you asking the question, “What the heck is a PGC?” it’s just DVD-speak for the titles in a DVD project. And I’m not talking about the opening or end credits, either; I’m talking about the titles that result, for example, from the timelines you create in an Encore DVD project. There is a subtle difference between a PGC and a VTS (title set), but that's not important right now.
2. Happily, recent versions of DVDD create a WAV file after ripping that will import directly into Encore. Versions prior to 3.2.0.0 would create a WAV file that had to be imported to, and exported from, a sound editing program like Adobe Audition, Goldwave or SoundForge before Encore would recognize it.
Events Tab: For convenience sake, I recommend setting “Set Program Mode” in the Startup section to “IFO”. That way, whenever you launch DVDD, it will look familiar to you. You may safely ignore all of the other tabs in the Settings dialog.
Ripping
1.Under the Input Tab of the main program window, select the PGC you want to rip. You can only do one at a time.
2.Switch to the Stream Processing Tab. Verify that Enable Stream Processing is checked.
3.Check or uncheck any or all of the video and audio streams that are listed. Highlight each one to verify that all audio streams are set to Demux and the video stream is set to Raw.
4.If you didn’t select Default Destination in the General Settings Tab, then you need to tell DVDD where to put the ripped files now.
5.Click on the big DVD-to-Disk icon.
6.DVDD will announce, quite loudly, when it has finished. At that point you can rename the files or import them as is into Encore.
I hope you find this guide useful and that it helps you get the most out of your investment in Adobe Encore DVD.

OK, I can't tell you what we are doing, you'll have to trust me that it's for a very good cause. I'll simplify the use case as an example. If I can do the following we'll be OK:
1) Read video/audo files from a DVD that we created
2) Open these files with the QuickTime Player, click on Export to Apple TV to create an output file.
I'd rather not do an interim conversion of the video data (like use a 3rd party app to convert to mp4 first and then read into QT, but I'm considering a conversion to DV) because that could seriously hurt the apps effectiveness. I also can't use another app (MPEG Streamclip, HandBrake, VisualHub, etc.) to do the conversion.

Video and Audio no longer line up
