No sync with audio for input files AVI MPEG4 23.976 fps

No sync with audio for input files AVI MPEG4 23.976 fps.
If i open in Premiere Pro CC any file AVI MPEG4 23.976 fps (with internal audio MP3 or AC3) i got growing out of sync from start to end of file, even while play it at internal media player of Premiere Pro CC for source file.
Using external audio files AC3 or MP3 not help.
In properties of source file i see 23.97 fps instead of 23.976 fps, and time of internal file is wrong.
If i try Clip > Modify > Interpreter Footage > custom settings to 23.976 time i see right time, but when i click "OK", custom fps saved as 23.98 fps instead of 23.976 fps and time of source goes wrong again.
So i always get bad sync such files in Premiere Pro CC while play or export them.
But in all media players, other editors, and in PluralEyes sync OK with all such files.
If i open M2TS or MP4 (H264 23.976 fps) source file, all OK, it it shows as 23.976 fps, time is right, and sync OK.
So i want to add automatic detection 23.976 fps instead of 23.97 fps for source AVI files with 23.976 fps.
Is it possible?

Yes, i know what XviD and DivX does not edit well in Premiere Pro. And because of that i create this topic "No sync with audio for input files AVI MPEG4 23.976 fps" and was hoping to get help in solving the problem, rather than stating that the problem really is.
XviD and DivX it is MPEG4.
Xvid (formerly "XviD") is a video codec library following the MPEG-4 standard, specifically MPEG-4 Part 2 Advanced Simple Profile (ASP).
http://en.wikipedia.org/wiki/Xvid
I have many old useful materials in XviD and DivX formats, and have no other formats versions for that material.
XviD and DivX are very compact formats to store video at acceptable quality and it is fully compatible with all players and editors for PC except Premiere Pro.
You suggest to convert them to another format (DV) to make compatible with Premiere Pro... It is not what i want.
Let me explaine:
1) Size of files
uploaded AVI XviD 1280x720 file with very good quality have size 1.9Gb (with audio AC3 2.0). If i convert it via VirtualDub from "AVI XviD" to AVI DVCPRO HD 1280x720 (without audio) it have size 35Gb, and quality is worst than at XviD-HD, and also converting take much time.
2) Compatibility with AC3 and MP3 audio inside AVI
AVI DV / AVI DVCPRO not compatible with AC3 and MP3 audio inside, only with PCM
http://en.wikipedia.org/wiki/DV
AVI XviD and DivX can use AC3, MP3, OGG audio without any problems.
Size of 1Hour 30Min "AC3 Stereo 48kHz 16bit 384Kbps" file is 257Mb
Size of 1Hour 30Min "PCM Stereo 48kHz 16bit" file is 1030Mb
3) I have and use hardware H264 encoder card "Matrox CompressHD" for export my material
http://www.matrox.com/video/en/products/compresshd/specs/
This card works only from Adobe Premiere Pro, so i can not use it from VirtualDub or other editing software.
So i need a full compatibility Adobe Premiere Pro with all popular standard formats of input files.
Here we see:
http://www.adobe.com/products/premiere/extend.html#Supportedvideoformats
Supported video formats:
"Adobe Premiere Pro CC leads the industry with incredible, thorough native media support, meaning you can edit virtually all of the major video, image, and audio formats natively without waiting."
As most PC users knows, AVI XviD it is a very popular free video format, and would be very useful if Adobe will make normal compatibility with that format in Premiere Pro.

HDMI to DVI with Audio for Input to an Old Sony TV

Just got an Apple TV box for Christmas. Apple TV output is HDMI and I have an old Sony Plasma TV that DO NOT have HDMI but it has DVI with Audio (L & R) inputs. I can buy a HDMI to DVI converter cable for about $10 but how do I get the sound from the Apple TV to my TV? Thank you much

You have two solutions -
Solution One - the way i did it was with a digital auido to RCA convertor - try here for an example http://www.amazon.co.uk/Digital-Optical-Coaxial-Toslink-Converter/dp/B0074JZ8ZW
or
solution two
a Kanex ATV PRo - converts HDMI to VGA and 3.5mm Audio
http://store.apple.com/us/product/H9139VC/A/kanex-atv-pro-hdmi-to-vga-adapter-wi th-audio-support
Both work but there is a cost and a bit of work.

Media Card Unreadable after sync with BBD for Mac

Everytime i sync with bbd for mac my media card is unreadable. I can see the file on the mac. bbd shows the card. I have to format the card and use a a windows pc to sync and rebuild the card. any ideas on how to fix this so i can sync with my mac. I am running snow leopard with the latest updates.
thanks in advance for your help.

Perhaps you're enjoying the bittersweet changes in iTunes 8.1. Many users, me included, have seen our 2nd gen shuffles become much more inconvenient to use after this upgrade.

Installed 4.01, now no audio for DV files....

HD files taken with my Sony SR-HD12 are fine, but I can no longer hear any audio for any files shot in DV. Anyone else have this issue?

Installing the 4.01 update has been known to reset sequence settings.
Have a look through all your sequence settings and be sure they make sense for your project.

Can i development program with EDK for uploading file to server?

Can I development program with EDK for uploading file to server?How to avoid same name of files?
Thanks!

Hi ,
thanks for the quick response.
but the problem is supppose i have a excel sheet with 16 rows and 13 columns(so data).
i am placing this file contents to appserver USING ABOVE fm.
after that i am reading the file from appserver to create SO(idoc),i need 1row-3column data and 2row-2c data.like that.
in unix we will get row data(after uploading to app server) as #mprn#2345# like this so easy to separate when reading.but in MS NT OS 1row data getting stored in different rows in Appserver.so difficult to read.
so the above mentioned FM is OS dependent or is there any way (any other FM) to get same kind of data in different OS.
PLEASE SUGGEST OTHER WISE I NEED TO CODE BASED ON OS.

Suddenly ICal & Address Book stopped syncing with Outlook for Mac

2 days ago, ICal and Address Book stopped syncing with Outlook for Mac 2011. I still have full functionality of Email in Outlook.
What is wrong and how can I fix it?

Any solution here yet? I have the same issue. After upgrading to Yosemite Outlook for mac kept requiring me to "rebuild identity database"
I did this many times so there were many new identities.
Finally I researched and found out that after the Yosemite update outlook would rebuild identity and once you do that there is a mismatch of your email account in outlook which just needs to be deleted and re-added to fix.
Now since then my outlook contacts and apple address book do not speak to each other.
If I make a new contact on my iphone and sync with my mac it will appear in apple address book.
If I make a new contact in outlook it will not appear on the iPhone.
So the phone is communicating and syncing with apple address book but wherever the apple address book goes to find the outlook contacts it must be using one of the older "identities"
Also now when I am in outlook and go from email to contacts it takes about 20 seconds to open the 5,300 contacts and it used to be instant.
Is there a way to view where outlook is getting the data? When I go into Outlook Preferences, Sync Services, "On My Computer:" is the one that is chosen so that should be good.
Any help?

Create playback controls for Timeline in sync with audio?

Hi All,
Technically, I've combined two questions into one. Firstly, can someone offer some insight on how to create playback controls for an Edge animation so the user can essentially "scrub" the timeline or navigate to a specific point on the timeline. I know you can create buttons to "sym.play()" different areas but I was wondering if there was a more streamlined solution (something similar to video playback controls.) Next, I'd like the user to be able to skip to different locations while the music remains in sync with the animations. I've created a few buttons to attempt to achieve this but the music plays independently regardless of where I jump to on the timeline.
Any help would be most appreciated.
Thanks in advance!

I had some ideas why that may be so, but then, when I thought about it, properly, i have no idea why it is that way. Maybe it is because audio has a higher priority than graphics, in OS X, but if I remember correctly, it was like this before OS X. Maybe there is an offset for latency compensation, but they made it too large. (it seems to be the same amount, no matter what the buffer size is)
just to make sure we are seeing the same thing. on my (somehat old) G4 I'm seeing about 60ms difference.

Video not in sync with audio or vice-versa

This is a last ditch effort to try to find some definitive help. Everyone has a sad story when things go awry with video capture. Here's mine: I recommended the Apple platform and iMovie for my wife for documenting a how-to for a particular hair style transition. Something she can't recapture. We used a MacBook Pro's built-in camera. All went well until she noticed from the beginning of the daily captures that the audio and video would fall out of sync within clips shortly after she started. After she was done and mentioned it, I discovered that the six or so clips that make up the project varied in their frame rates (project is set to 30). One clip with a frame rate of 28 is fine, but the rest have slower frame rates. The total project length is approximately 15-20 min....
Detaching the audio from the video and exporting to QuickTime (as suggested by most) makes no difference. I've also seen suggestions about moving the content to MPEG Steamclip and doing "something" with it but I'm not video editing savvy so exactly "what" nyone is supposed to do via that solution is an unknown..
I've been all ofver the web searching for a way to change all of the clip's frame rates to 30 fps since the one clip at 28 frames is acceptable. A foregone conclusion. However, I can't seem to find a way to do this anywhere.
Would really like to rescue the two weeks worth of work my wife put into this effort.
Any/all help appreciated thanks.

The basic problem you are facing is the use of the internal camera. It is designed for simple web cam usage rather than movie making. If you are making a Face Time call, the variable frame rate helps you, because when there is not a lot of movement, it will slow down the frames and give you better performance at a lower bandwidth. If the audio is a little off you do not care.
Long term, you can solve this by using a camcorder that shoots at a constant framerate.
For your immediate problem, I think that the suggestion to use MPEG Streamclip was a good one.
Basically, you would be dragging in this file with the variable frame rate and using MPEG Streamclip to save it out as a file with a constant framerate. You should now have a file at 30 fps with audio to match, within reason.
Try dragging your clip into MPEG Streamclip. Click the PLAY button so you can see that it plays. Then FILE/EXPORT TO QUICKTIME. For Compression, choose Apple Intermediate Codec. Leave the sound setting as Uncompressed. In the Frame Rate box, type 30. Click the check box for Frame Blending. Deselect the box that says Interlaced Scaling.
Finally, click the MAKE MOVIE button, and give at a name. Save it to a location where you can find it. You can then import this into iMovie if you want, but using FILE/IMPORT MOVIE in iMovie.

IChat video not in sync with audio

Hi Everyone,
For the past six months I have been trying to resolve issues with the video chat. It all started with me updating my brother-in-law's iMac G5 from Tiger to Leopard. Before the update we were able to video chat with no problems. Since the update the video has been out of sync with the audio. We tried all the remedies that have been posted (setting Quicktime Streaming to 1.5Mbps, limiting iChat bandwith to 500kbps, deleting the plist files in the preference folder) with no luck.
In the interim we have been using Skype to do our video chats, and that has been working just fine. However it has been bugging me that we can use iChat. We were hoping that the recent updates from Apple (10.5.5 and the Quicktime patch update) would have fixed the issue.
Now with all the updates we are partially fixed. The video feed that I get now is fine and looks like it is in sync with the audio. However, my brother-in-law sees me out of sync with the audio (the video is at least 10 sec behind the audio, and gets worse the longer we are connected)
We have tried all that we could think of including using the MobleMe and the .Mac accounts to log in but so far no luck. I'm wondering at this point if it is his modem (about 3 year old) that is causing him to get a delay? We tried connecting the modem directly to the iMac without the router, but it made no difference for the video sync issue.
The other issue we have been dealing with is his Linksys router (don't remember the model but, it's the one without the wireless capability) causing screen sharing not to work. He has tried disabling the firewall on the router but that has not worked. It will only work if we pull the router off and connect directly
Any help is appreciated, thanks in advance

Some modem features such as a SPI filter which checks the Incoming data stream for any app has the potential to get in the way.
It is not uncommon for the amount of data to arrive faster than the SPI part can deal with it.
If his router has an SPI filter/firewall then he should turn it off.
It may pay to Power down all items such as the routers and computer and potentially the modem and restart them all.
Also try Restarting his Mac with holding down AppleALT+PR until he hears three Start Up Bongs.
If this does not work get him to access the Linksys and on the front "Set Up" screen he will have an MTU settings. Get his to set this at 1492 (the default is 1500 and should be reduced by 8 each time if changed - it changes the packet size and may help).

Video doesn't sync with audio on network

Hey all, I'm somewhat of a newbie at using audio with Flash,
so hopefully someone can figure out what's happening:
I have a Flash movie that's about 2530 frames long, that
includes narration (which is broken out into 6 separate mp3 files),
each mp3 file begins playing where the previous one ends. The
entire movie is set for 30 fps.
The video syncs up to the narration perfectly when it is run
from my C:\ drive, but as soon as I copy it over to the network
(where everyone will have to access it from), the animations begin
to lag behind the narration. By the end of the 84 second movie, the
audio has ended at least 15 seconds before the last animation ends.
Any ideas?

I'm assuming that you are using the Sound class to control
the MP3 sounds? If that is the case then they will not be sync with
your timeline and if your animations are too much for the SWF to
stay at the 30fps rate then it will slow down to complete the
animations.
One way to sync them up would be to place them in a layer in
your timeline and then in the Parameters box at the bottom set the
Sync dropdown to Stream.
Then if your movie slows the audio and animations will still
be together.
This is not as flexible as you may currently have it but it
might work for you.

Rendering causes video to de-sync with audio

So, I'm a fan of making lets play videos. I got everything all recorded with my face cam and a separate audio track to put over that. I synced up the tracks so that they both match up and I have the better audio for my voice instead of what my camera picked up. So, the audio is perfectly synced up with the video. However, If I use any of the render settings like Render In to Out, it causes the video clip (just from my camera, game play footage is just fine) to become de-synced with both audio files. The original clip and the one recorded with my mic. Even stranger. Both audio tracks line up perfectly with each other, the video clip just seems to have moved and I cannot figure out why. I also think that rendering during export works perfectly fine without any kind of distortion (not that I have tested it to make sure). Any theories as to why the program is acting like this?

glad that got to the bottom of it, yeah, you can copy a clip and then paste attributes like the last commenter said to fix the distort issue. you might also try removing the distort and basic motion attributes if you're going to your native codec and haven't animated or blown anything up. but just for future reference, there is no special default final cut sequence setting. whenever you start out on a new one, you should double check to see what kind of sequence you've created. three ways to go about that (there are more):
1) the most basic way is in the Final Cut Pro -> Easy Setups... menu option, or if you want more options, then Final Cut Pro -> Audio/Video Settings... option. those both control the same things, but in different ways. play around in that if you're not familiar with it. but what you set there will be the "default" for new sequences that you create.
2) if you've already got a sequence in your project that you know is correct, you can duplicate that then delete all the stuff in there and start with that.
3) if you fire up a sequence, then drop a clip in that matches the native codec you want to work with, Final Cut will ask if you want to change the sequence settings to match the clip (unless you've turned that warning off). that'll ensure that you're working in the native codec of your footage, if that's what's desired.
you might want to start fresh with a new sequence after having done that and then pasting everything you've done into that as opposed to changing the sequence settings on the other one. it might work fine, but it also could have some glitchiness if you don't start with a fresh sequence. final cut is badass, but sometimes a little tempermental when you start tweaking the technical settings (even if you get it right).

Help! Windows Explorer crashes regularly when using "SharePoint" directory synced with OneDrive for Business

We are using SharePoint 2013 and I want to sync document libraries with
OneDrive for Business with my PC running Windows 7.
In general, it works, but my Windows Explorer crashes very often (after a few minutes) when I navigate in the synced directories and open files there (or copy files into them in Windows Explorer).
How can I find out what happens and how to avoid it?
remark:
We are still using Office 2007, so I installed only OneDrive for Business from the Office 2013 DVD and
deactivated all other components like Office 2013 by hand:
(so for example, the shared office feature or MS Info Path etc. were not installed)
Is there a crash log, where I can find more information about the crash?
Does OneDrive maybe need other components to be installed and can I install them without damaging my existing Office 2007 setup?

Did you check your Event Viewer for any errors during the time when Windows Explorer crashed?
Thanks for this hint!
The Log file says the following, so it seems to be WIDCOMM\Bluetooth Software\btncopy.dll
to be responsible for the crashing Windows Explorer

Any Mini DisplayPort to HDMI adapter with audio for macbook pro mid 2009

connecting MacBook Pro (15-inch, Mid 2009) to Hisense TV with audio?!?!!?
hello everyone.
if anyone is familar with successfully getting the older macbook pros that dont support audio out to stream and preform digital audio on a TV or has any helpful information that will get me familiar with trying to successfully stream audio and visual. and can PLEASE HELP ME in any way to understand what they know and teach me how to solve my problem id really appreciate it.
i want to connect my MacBook Pro (15-inch, Mid 2009) to my Hisense LED LCD TV, ModelNumber:40H3E and getting digital audio sound from my TV as well as video, but have no clue on how or where to even start to successfully pairing the two and getting sound.
I own a MacBook Pro (15-inch, Mid 2009) this MacBook model doesnt support an HDMI port. My MacBooks model has the Mini Displayport which supports video out but does not support audio out. Can someone help me by telling me exactly which Mini DisplayPort to HDMI adapter with audio will support my model MacBook Pro (15-inch, Mid 2009) and exactly what HDMI wire do i need to buy that will successfully preform digital audio and sadisfying quality visual through TV?
i have NO expierence with the proccess have NO knowledge about any of this or these Mini DisplayPort to HDMI adapters with audio. i have no idea what kind of adapter and HDMI cord to buy that will give me sound from my tv for my type of macbook. '
im not familar AT ALL with any of this so i hope me giving you my MacBook Pros make and model and my TV's model number will be enough information for someone to help me.
just please give me anything you can on this topic
thank you so much,

With a 2009 MacBook Pro, you need to use two connections to your TV: one for video and another one for audio. The miniDisplayPort on the 2009 models does not support audio, so you need a separate audio cable:
miniDisplayPort adapter for video - I use the Apple miniDisplayport-DVI adapter + a DVI-HDMI cable like this one
audio cable for audio - use a 3.5mm male stereo-to-2xRCA male cable like this one
Connect the miniDisplayport adapter + DVI/HDMI cable to your MacBook Pro's miniDisplayPort output and the HDMI input on your TV
Connect the audio cable to your MacBook Pro's audio out and your TV's audio in
The only potential gotcha is if your Hisense TV requires audio via the HDMI cable when you use an HDMI cable. The H3e user manual is unclear about this.

How can I sync with audio framerate?

I hope that there is an entirely different way of doing what I'm trying to do because I've run up against what seems like an insurmountable obstacle. I have been working on a project for many months and the last piece to figure out is synchronizing application actions with the audio framerate. I have seen other apps doing this successfully (but proabably written in C++, not Java) so it can be done with standard Wintel boxes - but I'm now concerned that it cannot be done using Java Sound.
My project attempts to animate sound with visual images (not video or pictures but more abstract visualizations based on the audio itself). It works fine when simply "listeing" and responding to the audio. The final step is to be able to sync specific abstract visualizations with precise points in the audio (frames or position in microseconds). I'm now wondering if what I need is handled by the soundcard (hardware) and not available through Java. I presumed that I would be able to rely on the soundcard to handle the realtime audio stream (using its clock) and I would simply wait for increments of a certain frame count that correspond to the refresh/trigger times for my visualizations. As it turns out, after a lot of experimenting with my configuration, I can't find a way to trigger a method in my application synchronized wiht a certain period in the audio being played. I am playing audio by writing to a SourceDataLine, and listening (using loopback, I believe) on a TargetDataLine. To give an idea of what I'm looking for, if a LineListener supported notification based on reaching a certain frame position in the audio stream, that would be great. That doesn't exist (that I could find, only START/STOP/OPEN/CLOSE events). I've been trying to set the buffer size on the TargetDataLine, and the number of bytes (frames) that I read from that TDL, to achieve a synchronization with the actual rate the audio is playing through the sound card. What I've seen is that the number of frames made available through TDL is not consistent. The read() method blocks for various times and with differing incremental frame positions as the TDL buffer is replenished in real time.
My goal is to be able to detect when a number of frames corresponding to 20 milliSeconds at 48kHz or 44.1kHz sample rate have been played through the sound card. Is this possible? I've not posted any code because the code I have isn't non-functional, it's just not capable of performing the task I am trying to achieve. Suggestions as to how I can refine my existing approach, or what other direction/implementation I can pursue will be greatly appreciated.
Edit: typo.

I think this breaks down into two related but separate issues:
First, the latency between writing audio (to a SDL) and when that audio is actually heard. If I could find a way to measure that, and it was consistent, I could adjust my processing and delivery of audio data to that SDL. As I tried to explain in my previous post, there will ALWAYS be a variability in the time when a given frame is processed in an SDL and when it sounds. Biggest variability is between the time required for the onset of the first sound (played via bytecode interpretation) and onsets of subsequent sounds (if played via code loaded into memory). But JVM switching also accounts for variability.
Have you seen this article?

"Real Time Low Latency Audio Processing in Java"
It does a good job of listing various factors that affect real-time audio latencies.
The other problem is that even if I were able to get an accurate measurement of the delay (latency) in the audio lines, if I then set system timers to cause action in sync with the audio frame rate based on audio sample rate (frame rate for uncompressed PCM audio) there is still an error path. Again from observation not direct knowledge, it seems that there is no direct link between the sound card clock (controlling real time frame rate and what should really be the master of all actions) and the system clock (which I would use as a surrogate for the actual sound card clock to synchronize my actions with the audio being heard). Even if I were to establish perfect synchronization at the start of a song, by the time 5 or 10 minutes of audio has been processed, I suspect there will be an accumulation of errors between the sound card clock and the system clock that becomes noticeable.The sound card clock and the system clock are perfectly in synch. The problem is the granularity of the system clock. With Microsoft, the clock info is only updated once every 15 msec or so. As a consequence of this, System.currentTimeMillis() will only report the time at the last update. Also, Thread.sleep(millis) and setting a Timer are subject to this constraint. The error doesn't accumulate, though. It is just an issue of having a reduced "granularity" that creates a predictable error. (System.nanoTime will always be more accurate--it is not subject to letting the OS determine the update frequency.)
As I wrote, there is a hack that allows you to increase the granularity of the OS clock interrupt. It involves setting an independant, background thread to sleep for the maximum amount of time, e.g. Thread.sleep(Long.Max_Value). This somehow forces the OS to use a higher granularity, and with Microsoft the accuracy becomes about 1 msec (comparable to Linux and Mac systems). I learned this at the forum Java-Gaming.org.
>
I'm open to ideas, criticism or examples of how I might acheive my goal. While it might not be practical or the only way, the best I can describe what I'm looking for is to have an audio-event driven system where I can determine a frame position corresponding to the audio being rendered in real time and trigger events to keep other actions synchronized with that audio. If a constant delay (latency) was maintained and measureable, that would be OK.
This is a difficult problem.
Agreed about the difficulty!
Given all this, I think the questions are:
1) how much in advance do you know about given frames that you wish to use as cues?
2) how well can you guestimate an anchor point? (and, is there a way to improve upon the guess with feedback?)
3) how accurately can you trigger the visual cue?
Regardless of when Java decides to process a frame, it DOES manage to keep the playback steady. Thus, if you focus your efforts on finding an ANCHOR (for example, the nanoTime, or "close enough" approximation, when the first frame sounds) that you can use as a reference point for the duration of the sound, then you can use that point to calculate conversions between the frame count of the sound and the time it can be expected to play.
For example, if the frame is 44100 and you estimate frame 0 was at time 1336426670003 (System.currentTimeMillis), then set a Timer, in advance, to trigger the visual cue at 1336426671003 (I'm adding 1000 msec). The level of accuracy will remain the same regardless of the frame number and duration involved as long as you use the same anchor (and the sound playback is not interrupted).

Apple TV not syncing with iTunes for purchased movies

Hi, I purchased two movies on iTunes and neither one is syncing with my Apple TV. All music is syncing perfectly fine.
The Apple TV is set to Custom Sync. On the movies tab of the Apple TV device in iTunes I have selected sync all movies since the two I am trying to sync are the only two I have purchased. When I click sync it takes about 15 seconds and then finishes with no additional files transferred. I have also tried changing the setting from sync all movies to sync selected with the two movies selected beneath. Neither works for me. Any ideas on why?
I am using iTunes 8.2

in iTunes in the left hand panel under "Library" click on "Movies".. in the right hand list... find the movies that you bought. on far right of each row/item in the list is a checkbox... this checkbox must be checked or the movie will not sync... is that checkbox checked?

No sync with audio for input files AVI MPEG4 23.976 fps
