Audio and video cpompression over anetwork.

Hello every body,,
I want to transmit audio and vedio over internet,, and as every body know the transmition of audio and vedio has some delay over the internet...
so can i made some compression to audio and vedio streams at the sender side and then transmit them and extract this commpression at the receiver side..???

i dont think you can compress to a lower quality when sending and then decompress to a higer quality when receiving. actually, h263 and jpeg are already compressed. what you can do is just degrade the quality of a jpeg or h263 streams and receive it like that. the lowest one-way video stream bandwidth i could go down to w/o major programming was 80-90kbps with h263 codec. there's probably a way to make it even less, but it requires a deeper programming to reduce frame rate, because standard JMF ways to alter frame rate dont work (i've tried at least 3 different ways). if you can do it, you can probably get a decent quality one-way video stream with as low as 30kbps

Synchronize audio and video over RTP

Hi all,
I am new in jmf. Please any one tell me, how to synchronize audio and video streams, when we capture thru audio and video capture devices and send it over network thru rtp protocol and receive at client side. How to syncnronize at client side? Please send me reply if any one have solution in jmf.
Thanks in advance.

Does anyone know about how this is done? I'm doing a videoconference thing with jmf, QoS is a required componenet! So if anyone knows about how this is done, plz share with discussion! All I know so far is that I can buffer the incoming streams to some extend then call syncStart() to start the video with the starting time of the video!

Does 2 firewire audio and video interface can work together on FCP ?

hello,
My audio interface is a TC Electronic Konnekt 24D
my video interface is a Canopus ADVC 110
my hard drives are plugged in firewire too
and I use Final Cut Pro 5.0.4
So, the konnekt is recognized by FCP only when the Canopus is not plugged. And even then, the audio sometimes drop out and sometimes causes the app to crash, so that I have to trash the preferences
When I plug the Canopus, the Konnekt 24D is recognised by OS X but not FCP
I want to use the voice over tool with the konnekt 24D, so what should I do ?
Does 2 firewire audio and video interface can work together ?
If so, maybe I only have a driver problem from TC Electronic.
But if not, I have to change this interface. Let me know if only RME, MOTU, Presonus and Edirol work, as it is said on apple's webpage for hardware compatibility
thanks

The 1082 does show up as a possible input when I open
the VO tool.
Ok. So an audio interface can be plugged to FCP without crashing the app. Because of the Konnekt driver problem, I wasn't shure of this.
I use my Aja box for export & external monitoring.
All my audio sources run back into the Tascam and I
use the analog mixer in the 1082 to monitor different
sources.
When I view external video, the audio follows it to
keep sync.
that's exactly what I want with other I/O interfaces. I'd like to monitor video with the canopus ADVC 110, and monitor audio with the Konnekt 24D (or another interface if this one is not compatible)
I also imput dailies with a deck or a camera (DV or HDV) but that's not the point here.
I want to imput audio with the Konnekt 24D because of its audio quality. Not audio sync to video dailies. But voice over, in sync with FCP video playback (for me, tha ADVC 110)

I am trying to export a video from Premiere Pro. I have both audio and video checked and the sequence is active but only the audio exports. There is no video at all. Can anyone tell me how to get the video to export. It was working fine until today.

Premiere Pro CC has been working fine until today. I have completed my sequence and it is active. I have both audio and video checked when I am exporting using H.264 with Match Source Hi bitrate. I am choosing entire sequence. The audio exports but the video and title does not. Can anyone tell me how to troubleshoot this so I can complete this project? Please!

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Photo Booth Audio and Video not in sync!

I am a YouTube musician. When I go to record I find it easiest to use the video feature in Photo Booth. However, ever since I upgraded to Mountain Lion my audio and video in my videos has been off of one another. They start off together but by the end of the video the audio is ahead of the video. When I went to try and see where it messes up I found that the video jumps frames creating almost a transition effect. I don't know how to fix this and would really like your help!

Audio and Video out of sync in PPCS6.0.3

I imported a video clip into Adobe Premiere Pro CS 6.0.3.   I noticed that the video and audio are out of sync.   I played the video file through Windows Media Player and the audio/video are in sync.
However at 8min42sec, I noticed that the video becomes garbled but the audio track is fine.   The entire video clip is about 10min24sec.
I would like to trim the video file at the 8min42sec.   However everytime, I import it into Adobe Premiere, the audio and video are out of sync.   I wonder if Premiere is trying to stretch the video track to compensate.    Is there a way to import the video clip without having Adobe Premiere manipulating it.   Any suggestions are appreciated. Thanks

Audio and video out of sync on converted AVI file

I am trying to convert a DVD to an AVI for playback on a device. When I import the DVD and publish it as an .AVI the output audio and video are out of sync. After about an hour of playback the audio lags the video by a full second. How can I correct this problem?

Walter0325
If you have Premiere Elements 12 on Windows 8 and you want to rip VOBs from the DVD-VIDEO to export subsequently to DV AVI, here are the details....
1. Do you have DVD-VIDEO standard or widescreen? Set the Premiere Elements 12 project preset manually.
File Menu/New/Project. Set the project preset to NTSC or PAL DV Standard or NTSC or PAL DV Widescreen depending on what you have.
Before you exit the new project dialog, make sure that you have a check mark next to Force Selected Project Setting on this Project.
2. In the Premiere Elements workspace, use Add Media/DVD camera or computer drive/Video Importer to get the VOBs (only the ones in the series VTS_01_1.VOB. Set to a folder in the Save In: location. Check mark next to Insert in Timeline. Hit Get Media.
3. If you have an orange line OVER the Timeline content, press the Enter key to get the best possible preview of what you have on that Timeline.
If after all that, the audio is out of sync, then use the Command Prompt method to get the individual VOBs into a single file with all the VOBs seamlessly merged. This worked nicely for a recent user here. See details in my blog post how to for the Command Prompt way.

Depending on your results, more information may be requested about the specific properties of what you have on that DVD disc.

Audio and video are not synched

I'm just beginning with FXP X (8), and just added a file to my event library, and created a new project. Dragged my first clip into the story line, and discovered that the audio and video are not syched. This is original footage from a video camera, no modifications or added tracks. But clearly the words of the speaker on camera are not synched with the video, both in the event library and in the story line clip. Is this operator error (lol)? TIA for any help, I'm stuck on square one.

You can right click on your clip in the storyline and Detach Audio.
After that, you can slide the audio until it's in sync or if it changes sync over the length of the clip, there is a way to correct that as well.
First, in the video, skim the playhead until you can see something that will "mark" a specific start of a sound and set a Marker (type M). Then select the audio portion (already detached) and find the start of the matching sound and type M (adds marker to the audio.) Turn on snapping and slide the audio until the two markers snap.
If you need to correct sync drift, use the same technique for markers near the end of the clip, but instead of sliding the complete audio clip, Retime the audio clip (type command-R) (set the playhead over the video marker - snapping won't work when retiming) and adjust the end of the audio until the two markers match up. Preserve Pitch (from the Retime menu) should already be selected.

IChat Audio and Video not working correctly...

Hi.
I recently upgraded to Snow Leopard. Before upgrading, I was able to video chat with little to no problem with family over iChat. I just tried it again today for the first time since upgrading to Snow Leopard and the audio is barely working (can only make out every few words, if that), and the video is extremely distorted to where you can sometimes not even tell there are people there. It gets all pixelated and weird. I tried doing the chat with Google Talk and then again with Skype, and had just as many problems with those. My family is using a Mac with an older OS, and they can see and hear me perfectly fine. I'm not sure if the problem is with my computer or with theirs, or if it's just a communication problem, but any ideas would be really helpful. Thanks!

After iChat developed missing audio and video pixellation problem post Snow Leopard installation at my mother-in-law's machine (and ours), I tried the usual decrease the bandwidth fix to no avail.
The solution that actually fixed the probem was to turn off port forwarding protocol on her Time Capsule and our Airport Extreme. Things are now working smoothly even at 500 kbps settings on both ends.
An interesting aside... Turning off port forwarding for ssh to her machine doesn't kill the ssh port tunnel from the outside LAN to her mac. It looks like iChat and the Time Capsule keep an incoming ssh tunnel open even if you have disabled port forwarding on the Time Capsule. I suspect this "secret" opening of ports is the magic of why iChat and screen sharing have been so much easier to set up when a Mac is behind an Apple router. 3rd party routers need ports manually forwarded to the Mac. Apple routers just worked ---- and it looks like Apple does it by invisibly opening ports on their routers when a Mac runs iChat.
Pretty nifty, but also silently opens a security hole that you may THINK you closed. SL seems to trip up over this arrangement when you also turn on Port Mapping Protocol and manually assign ports to forward.
At any rate, it wasn't the data rate, it was a new bad interaction between the Apple Router's Port Mapping Protocol and iChat 5. Turn off PMP on the airport and all becomes well once more.

Poor Audio and Video Quality

Using IDVD to burn iMovie containing pictures and music and am getting very poor quality audio and video. The video is very low resolution, lacking clarity and definition, and the audio comes out really flat with over-saturated vocals that is unpleasant to listen to.
The content was made from iMovie 11, importing photos from iPhoto and iTunes music.
I exported the movie via Share->Export Movie-> HD 1080P
In iDVD 7.1.2 I imported the movie (actually several) into a slideshow menu item.
I used the iDVD encoding preferences set at 'Best Performance' and 'Professional Quality' with no difference between the two
Then to ensure it wasn't the DVD disk causing the problem, I used the 'Save as Disc Image', and validated the file image saved to disk had the same quality issues as the burned DVD.
Then to eliminate the iMovie as the problem, ran a test and used an iPhoto slideshow in place of the iMovie, and it also has the same low quality issues.
I have observed that using the iDVD viewing capabilities, the A/V quality is fine. Its after the burn to disk the problem occurs.
At this point I'm not sure what to try. I'm viewing the DVD on my 50" widescreen TV using Sony DVD player.
A year or so back I did similar steps and the DVD came out fine... the sound quality was excellent and the video quality while not outstanding, was reasonable.
Any ideas -- I'm really stumped.

Hi
In iMovie'11 - I do (not use Share to iDVD)
• Share to Media Browser - AND AS Large - NOT HD ! (result will not be better but rather WORSE)
• In iDVD I import from Media button and Movie tab.

Can't drag audio and video together?

I have numerous assets in this dvd project. I'm setting up a button to play 10 commercials in a row, a "play all" button.
I'm editing the 10 commercials in what looks like a mini-video editor, with the video track and audio tracks shown.
PROBLEM:
When I grab the video to change the order of my "play all", the audio doesn't move with it. For instance, I'm shifting commercial #3 to become commercial #1. In order for Audio from Commercial #3 to become audio for commercial #1, I have to shift audio #2-10 over to the right to create space for Audio Commercial #3 to insert there. VERY FRUSTRATING and painstaking. And if you accidentally clip a bit off the end or front of an audio portion (easy to do in these tiny little tracks), the sync' is off for the rest of the spots!
I called Apple "tech support", and the rep' told me you can't drag audio and video together, and made up some excuse about 'this should already be done in Final Cut'. What? I'm just bringing in QuickTime files as assets. Why can't I lock audio and video together?
Incidentally, Apple's Tech Support is useless you spend $199, or "$799 for a year". This cost was NOT made clear in the original purchase of the product. I'd prefer spending $1000 for a "PROFESSIONAL APPLICATION" and have good tech support included!
Arrrrgh!
G4 dual 1.25 gig - 1 gig ram Mac OS X (10.3.8) DVD Studio "Pro" 4

Once in the track, A and V don't get moved together.
I usually just rebuild the track order from scratch anyway because you can easily lose sync easilly when you are shuffling clip order.

When exporting separate audio and video streams, the audio drifts out of sync

So this is my first slightly larger project in Final Cut Pro X.
When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

TS1362 All of the movies I have rented or purchased from iTunes in the last 4 months fail to play properly. The audio and video are constantly out of sync. I have followed the iTunes suggestions to correct this, however nothing has worked. (Windows 8)

I am using a Dell inspiron 14z, with Windows 8, and before that a Dell with Windows XP. This is also happening on my iPad. For the last four months, none of the movies or television shows I have rented or purchased from iTunes have played properly. The audio and video are out of sync. I have tried the troubleshooting measures iTunes suggested, however nothing seems to work. I have read on the community that this has been a problem for users in the past, and have attempted to try some of the fixes individual users have suggested also. Again, nothing seems to work. At this point I am frustrated, as we purchase or rent almost exclusively from iTunes. I would appreciate a support-staff person response. Thank you so much.

this problem has been going on for windows users for over a year now.

Please help with audio and video not syncing.

I'm using Encore 3, and have already authored a DVD a month ago without a glitch. The following are the same steps I used, but this time around, the video and audio in Encore are not syncing.
Here's what I've done.
1) I export my Final Cut projects to .mov using the following settings (Share > Master File).
Format: Video and Audio
Video codec: H.264
Resolution: 1920x1080
Audio file format: Quicktime Movie (AAC)
Include chapter markers: Unchecked
Roles as: Quicktime Movie
2) I run the .mov file in Compressor using the "Disc Burning" preset.
3) I then import the .ac3 and .m2v files that Compressor created into Encore.
4) In Encore, I select both files and go to New > Timeline.
In the Timeline window, the durations on both are the same. But I don't understand why the audio and video are not synced when I preview or when I burn a test DVD. The audio comes in just a tad late.
Video Clip:
Source In: 00;00;00;00
Duration: 00;02;33;29
In-Point: 00;00;00;00
Out-Point: 00;02;33;29
Audio Clip:
Source In: 00;00;00;00
Duration: 00;02;34;00
In-Point: 00;00;00;00
Out-Point: 00;02;34;00
What's puzzling is that two of the 10 videos I've import to Encore are synced perfectly -- same export settings from FCP, same settings Compressor.
Please help.
Thanks!
Mark

Hi Mark.
Do you have any situations where there is more than one video file in a timeline?
Secondly - why are you using H264 HD files for a DVD? This is using lossy compression to make the H264, which is in turn then scaled & even further bitrate reduced for M2V.
I would give it a try rendering an SD video file for use in Encore - not the H264 - and starting out with Dolby Digital or LPCM audio, not AAC.
As with all DVD authoring programs, Encore works best with DVD compliant assets - which you are most definitely using - but I still think you are over-complicating things by using H264/AAC at all.
Eliminating this may help.

Having trouble Audio and Video Syncing on iTune

Having trouble Audio and Video Syncing on iTune anyone know how to repair?

Here are two suggestions:
If everything is pretty much in sync until 17 minutes in, do a re sync every ten minutes. This should ensure that, even if the sync drifts by a few frames over 10 mins, the video will not seem distinctly out of sync at any time.
Another approach would be to do an overall re-sync in QuickTime Pro (which I believe is part of the FCP package).
You would need to use QTPro to trim,the video file to remove any surplus seconds of material at the beginning and end. Then open the audio file in QT Pro and trim that if necessary. It may be a slightly more complicated to do this at the beginning because, if the audio does not come in immediately, you'll need to make sure that you have the right amount of silence at the start of the file to match the video before the audio begins. This should leave you with video and audio files of the same length.
Then, in the drop menus of your QT, select and copy the audio track. Switching to the QT video file, in the drop down menus, click on add track.
Hope one or other of these May be some help to you.
