Poor audio quality when importing. Help?

Hello, everyone!
I have been having trouble importing videos recently, as it sounds good when played outside of premiere, but as soon as I import it into the program, the audio loses 70, maybe 80% of its quality immediately.
The video format is AVI and the audio qualiy is 128kbps, 2 stereo channels, at a 44kHz audio sampling rate.
The video (don't know if this matters, but can't hurt) has a data rate of 200kbps, 328 bits @ 29FPS.
I've tried everything in order to match the project pre-definitions and the sound input, with no success at all. It always sounds bad and I don't know what to do anymore.
Any help will be greatly appreciated.

Well, it says in the properties "2 stereo channels" but Premiere seems to identify it as mono for some reason. Tried creating mono and stereo projects, didn't help.

Poor audio quality when importing CDs (but only some of them)

I am experiencing a bizarre audio quality problem:
When playing or importing tracks from CDs into iTunes 9.0.2, on some CDs there is very poor quality and an audible crackling (like an old scratched lp)whereas on others the quality is perfect. This translates to the iPod as well.
I've looked all over the internet and am now thoroughly confused. Any advice would be greatly appreciated.

If you are hearing it both on iTunes playback and on the iPod, it is probably an importing problem, i.e. the track is bad.
When you import, do your Import Settings use Error Correction? If not, turn it on and re-rip one of the problem tracks.

Poor photo quality when importing to iMovie

I imported some photos to make a slide show with added soundtrack. When I select a photo and click the "Show photo settings" it looks crisp and clear, just as it was shot. As soon as I deselect the "Show photo settings" button it looks blurred, pixeled and fuzzy, just an ultra low quality photo. The end result of the video slide show it's just a low end work.
I just want to burn some DVD's to show my photographic work, but such a poor photo quality it's not going to help me achieve what I had intended.
Any clues anyone???

I'd like to follow up on your answer re: resolving poor photo quality. It seems the mere act of bringing photos into iMovie degrades the quality. You look at the photo in the preview window and it looks crisp. But then when you "ADD" it to the timeline, it becomes almost fuzzy. Isn't iMovie rendering the photos then and there as you bring them into the timeline? I cannot seem to make the photos look sharper and it doesn't seem to help doing the slideshow first in iPhoto, which I'd rather not do anyway.
Any suggestions?

Poor Video quality when importing from SONY DCR-SR100

I am brand new to Mac and iMovie and FCE. One of the reasons I switched to Mac was frustration over poor video output from Windows based video editing programs. When importing video from the SR100 into iMovie and then iDVD, the DVD quality is noticeably poorer than when the camera is connected directly to the Plasma TV. I have been reading these forums and loaded MPEG Streamclip and purchased the Quicktime MPEG2 Download, but I still can't get the video output to look as good as the camera. I obviously have some learning to do, but is there any hope of achieving equal quality output from a DVD as straight from the camera? Is there a good source of information/textbook on this topic? The biggest improvement comes from using the "de-interlace" option in MPEG Streamclip, but the overall quality of the video appears washed out and somewhat blotchy compared to the direct camera footage.

Welcome to the macworld! What imovie does incredibly well is make it easy to create fun and interesting movies. I have used both for several years and only recently with some packages such as adobe premiere elements has the windows world kept up with the mac with respect to ease of use! And even know the packages are still not as easy as imovie. Anyway, with respect to your post and getting the video quality to the best possible output quality using DV material, you are on the right path. The best workflow is to use streamclip and de-interlace prior to editing in imovie. I am not sure if you are doing that yet with your workflow. Yes, its an extra step, but it is well worth it to avoid imovie dropping a field upon export. You can play around with the adjustments to increase contrast, color and et al on the adjustment button. Another option is shooting progressive.
To set expectations, it is second generation footage the minute its imported. However, you should be still getting very good results. FCE gets footage closer to the original footage since it is a true DV editor and uses both fields, but imovie is still preferred by me because of how easy it is to skim, tag and find the material you want then easily do transitions and ken burns for photo's. Fantastic. The way i look at it....watching footage straight from the camera is the worst quality you can get -- It's like listening to your spouse talk and talk and talk and never get to the point until you forget what that point was....editing gets the footage straight to the point....thats quality!

Poor image quality when importing SWF

I maintain a site for a photographer and as he added more
images the SWF got to be very large, so I split up the site and
used a main page to import the smaller SWF files into a target.
However, I found that all my clean crisp images become dull when
imported but still look sharp in the SWF itself. I tied to find all
the JPEG settings and push them up but still with no luck. Does
anybody have any insight to why this is happening?

Hello micsaint111111111111,
The reason they look more blurry than in the original swf is
that you are
dealing with dual compression from the original swf AND the
swf you are loading
the images into.
The easiest/best way to import your jpgs would be using
LoadMovie to load
the actual jpg files. That keeps all the jpgs separate so
your swf file will
be tiny. Plus the quality will be the same as the original
jpg.
That said- have you gone into your swfs and changed the
default image quality
on each of the images to 90 or 100? You do that in your
library by right-clicking
on the actual images and then going to Properties and
unchecking "Use document
default quality". That is one issue that a lot of people seem
to miss and
it might help if you don't want to recode your Flash with the
LoadMovie method.

Poor photo quality when importing slide show into Elements 10

Hello,
I'm using Elements and Photoshop Elements 10 on Vista.
What I'm trying to do is import a slide show I made in Photoshop in to a movie I'm making so that the slide show appears as a menu item and I don't have to include a separate disk for the pictures. I've sucessfully imported it, added the menu marker and the disc works, but the photo quality is really crappy. When I play the slide show on its own, the pictures are fine. What am I missing?
Thanks in advance!

Welcome to the forum.
They work on several levels:
A subscriber comes with a problem/question, and then, hopefully, someone will have an answer
A subscriber comes with a problem/question in mind, and then finds other threads, very similar, and hopefully gets the answer
A subscriber comes to read, to pick up ideas, etc.
In your case, it appears that # 2 worked, just as it should.
As for your question, PrE can produce SlideShows for display from DVD-Video, as good as it gets. Where commercial DVD-Videos enter a different realm, is with Video footage, with motion. There, Hollywood uses special Transcoding software, that allows for many, many more passes to identify the areas of motion, to Transcode at just the right Bit-Rate, for best results. PrE does that with but two passes, unlike the US $ 500,000 programs, staffed by highly-trained experts, who do nothing but Transcoding, all day long. PrE is limited in that respect, but with SlideShows, it will be able to apply the highest Bit-Rate (the DVD-specs. are strict here, so, though higher Bit-Rate = higher quality, DVD-Video can ONLY go so far.) Also, Hollywood uses DVD-9's (DL) so that more Duration can be authored to disc, at the highest-allowed Bit-Rate, for each segment of the Video. With a SlideShow, the Bit-Rate will be as high as the DVD-specs. allow, and per the Duration of the SlideShow vs the capacity of the disc.
Now, there are some other considerations, such as the limited Color Gamut (and Gamma) of DVD-Video vs display on a calibrated computer monitor, or a calibrated Broadcast monitor. One needs to study that limited and different Color Gamut, and perhaps adjust the colors first, in Photoshop. PrE is not designed for Broadcast output, so lacks many of the Tools, that PrPro has. Also, very few PrE users have a calibrated Broadcast monitor hooked up for Color Grading. Last, even if one has produced the ultimate output, with full understanding of the Color Gamut, and used a perfectly calibrated Broadcast monitor, there is no telling what the calibration of the client's monitor (computer, or TV) will be. What is perfect on a calibrated Broadcast monitor might look great on the client's setup, or perhaps not. A Broadcast Engineer can only adjust to standards, and hope for the best, when the disc hits the public. Same for Audio. Who knows what "Aunt Marge" has to play back the DVD-Video?
For ultimate results, I would create a Timeline with a few Still Images, but with each adjusted in slightly different ways in Photoshop. Add a Title, like a Lower-Third, with the Color and Gamma settings over each version, maybe 5 variations, that are slightly different. PS allows one to adjust Colors and Gamma in many ways, so explore. Then, author that Timeline to DVD-Video, using high-quality media, and test on their DVD player/TV setup. See which version looks best, and note the specifics from that Title. Use that to process the actual Still Images for the DVD SlideShow.
Also remember, if one has set things up ideally, they will have calibrated their system and Photoshop. As Photoshop is a Color Managed Workspace, things will be, as good as it gets. DVD-Video, and TV's are NOT Color Managed Workspaces, and most consumer TV's are out of general calibration, having just the generic setting from the factory. Nothing can be done about that.
As mentioned above, if the playback is for a computer (not a DVD player and TV), then better Color and Gamma might be achieved by doing an AV file, and then burning that to a DVD-Data disc, for delivery. However, one still has the variables of the client's computer, its monitor and even the software player used. All play a big role in how that AV file will play for them.
Good luck, and I wish there was an "iron-clad" answer, as to how to achieve the ultimate results, but there are so very many variables involved.

Poor audio quality when streaming from 4s

if i play tv programe on iPhone, the audio is ok, when i airplay to ATV some of the audio is muffled. any ideas what is causing this? I have switched sound check off.

Welcome to the Apple Community.
It might be a network issue. How far are all the devices from the router. Do you experience interference.
Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel.
Have you tied restarting both devices.

Poor Audio Quality From Exchange 2010 UM

Hi,
I'm experiencing an issue with our Exchange 2010 Unified Messaging system in that the audio quality is suddenly rather poor. We are using Cisco Callmanager 7 for our phone system. When you call an automated attendant, hit the "messages"
button or call the extension to go to voicemail, the audio you hear "crackles," or sounds like it is skipping slightly in that there are brief but noticable interruptions in the audio.
The audio quality issue only occurs when you are connected to voicemail or automated attendants, but not when conversing to other people on phone calls, so that leads me to believe either some interoperability between CM and Exchange UM is malfunctioning, or
just something in UM is a problem. Also, if you listen to voice messages through the computer instead of over the phone, the quality is fine. The problem seems to be mainly with calling in to the UM system.
What can I do to properly troubleshoot this? I have found the Exchange 2010 UM Troubleshooting Assistant, but I have to wait another 2 weeks before I can install Service Pack 1 due to downtime window restrictions. I'm not coming up with a lot of
documentation involving this, so if anyone has any information they think might help me get to the bottom of this I would apprecaite it.
Thank you.

Cisco Callmanger and UM are on the same LAN.
I highly doubt that QoS is the culprit here, simply because there aren't any issues with phone calls. If QoS was dropping VOIP packets, then IP phone to IP phone calls would also have poor audio quality. If I call somebody on another IP
phone on the LAN, the audio quality is perfect. It is only when you are connected to the UM system that you hear the poor audio quality -- either listening to voicemail prompts, listening to actual voicemails, listening to the automated attendant --
anything in which UM is on one end of the phone call.
It also seems strange that this is somewhat intermittent. When the issue first occurred, it was definitely happening every time you called in to the UM system and I could repeat the issue by simply pushing my messages button and listening to the welcome
and prompt for a PIN. I restarted the Exchange server at night, and the next day it was intermittent with people calling the help desk to say they were getting poor audio quality from UM but when I tried to repeat the issue I could not.
I also have users complaining of intermittent slowness when using Outlook, which may be totally unrelated. I have been running Perf logs on the Exchange server for the last couple of weeks othe CPU, Network Connections, Exchange RPC totals, etc.
and can't find anything that is using too many resources.

FAQ: How do I troubleshoot audio issues when importing .MTS files?

Hello. The link FAQ: How do I troubleshoot audio issues when importing .MTS files?
does not work, and i need the answer please. My imported MTS clips are not playing back audio because it seems that no audio imported with the video. Thanks, Don.

Hi there
Audio plays when the object with the audio assigned appears. This is why you hear it when the Button appears.
Try assigning the audio instead to the object that appears when you click the button. Perhaps the caption.
Cheers... Rick

Losing audio quality when exporting from premiere pro

I have now had this happen with two different videos. I play the video in premiere pro and the audio is fine. I export the video and lose most of the quality of the audio portion. One project is a music session when exported I only get the main vocal the drums aren't audible only a buzz sound is made where the kick drum would usually come in. On another project is a thank you video for a family member and the audio is distorted after being exported. The audio sounds fine inside of the session. Once exported the audio will still work fine on my computer and my iphone 5s as long as I'm wearing headphones, once I try to play the video through my iphone 5s speakers the audio quality is gone, making the noises as previously stated. My iphone can still play other tracks fine but videos and audio exported from Premiere Pro are distorted. Any advice on how I can export the video so I wont lose audio quality when playing the video on an iphone? I know it's not my iphone speakers, they play other songs just fine.

The source files as far as the audio goes are wav files that I've pulled off of my desktop. My sequence settings are 1920 by 1080 at 29.97 frames per second. The export settings are H.264 with the preset YouTube (HD 1080 29.97 FPS) and I've also tried HD video 1080p 29.97 FPS. If this isn't enough information please let me know I'm in the learning phase. Audio wise the quality is set to high and I'm exporting at 4800 kh and a bit rate of 190. I've also tried a bit rate of 320 and 264 I think it is and still had the same problems. Let me know if I need to do screen shots I really want to figure this out.
Thanks for your help!

Audio problem when importing video files.

Hello everyone,
I just started using FCP X a few days ago for a university project and I seem to encounter an audio problem when importing videos in .mp4, .mov format or via the import from camera option.
Indeed I need to import videos in .mp4 and .mov format into FCP X. The import in itself is normal I can see my videos into the events/clips library and if I play them from the library I can hear the sound quite perfectly.
However, when I want to edit my videos and put it in the timeline, there is no audio. As a result I started to think that my videos could be the problem so I tried the option "import from camera" option using the Isight camera of my macbook pro but the same things happened. I could hear the sound from the events/clips library but not from the timeline (I can't see any audiowaves in the timeline).
I found a solution using quicktime and extracting the audio of the video in .m4a then importing the videos files and the audi files corresponding but it's a long process and a waste of time as FCP X should be able to import the audio of my video into the timeline directly. Especially if it can read it from events/clips library.
I hope I explained myself clearly and you could help me resolve my problem.
Cheers
Christophe
PS: I'm using FCP X version 10.0

Update to 10.0.5.
You have an incorrect setting when you edit. Try trashing your preferences. Post screen shots of your timeline and toolbar.

Lync 2013 and Audiocodes ESBC Mediant 1000 - poor audio quality

Bit of an odd issue that I've been looking into for the past few weeks - our part of our change from a pilot Lync install to production we have had an Audiocodes ESBC Mediant 1000 installed to serve as a Media Gateway between the Lync Mediation Server and
our Gamma Telecom provided SIP trunk.
However under certain situations my users are reporting exceptionally poor audio quality with the Lync server reporting website reporting a very high packet loss and our ESBC reporting a high 'Average voice delay' (often greater than 80ms).
I have established that by taking these steps the issue can be replicated with almost impunity-
Make incoming call from mobile phone (or landline) - pickup call on Lync Deskphone (CX300/CX500/CX600 and VVX410 all have the same).
Begin a consultative call transfer with an external (another mobile/landline) or internal number which places the incoming call on hold.
Complete the call transfer - at this point the audio quality is still as expected.
Begin a new call from a Lync phone to an external number - at this point the audio quality for the phone call that has been transferred and the new call instantly degrades.
My basic topology is-
Fibre Leased Line - Cat5e cable - Router - Cat5e cable - DMZ Switch - Cat5e cable - Audiocodes Mediant 1000 - Cat5e cable - Servers VLAN - Switch - Fibre - Core switch (layer 3) - Fibre - VMWare Host (ESXI v5) - Lync Server (VMNET 3 adapter)
I have been able to replicate the issue when using both TCP and TLS between the Lync Mediation Server and the Audiocodes gateway.
Over the next day or so I will be looking to get the SIP trunk connected directly to the Lync server to see if that makes any difference (ruling out the Mediant 1000 as a possible cause) but in the meantime does anyone have any ideas as to what could be
causing this most weird situation?

Hi,
Please disassociate the Edge Server from the Mediation and check the delay again.
Please check port 3478 to the internal interface of the Edge Server from all internal clients (including the Mediation Server).
Best Regards,

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?
That would depend on your work flow. MOV is the generic QuickTime file container and is not related to any particular data compression format. If you perform a simple "Save" or "Save As..." action that merely copies the data in the WAV file to an MOV file, then the data remains unchanged and maintains its original quality. If, on the other hand, your transcode/re-compress the original data to a different compression format, then there is always the potential for some loss in quality. Depending on the codec and/or settings, the potential loss could be inaudible to severe.

Poor sound quality when using air play

How do I fix poor sound quality when using air play with my Denon receiver?

I am not too sure if this is affected by BT software stack or RF design...
iPhone 3G with FW 2.x provides Cisco VPN as well as Email support for corporate usage. However, it's weird that business man wouldn't want to use BT headset and talk to people... We are not asking about new feature support, like A2DP, but reliable, stable BT connection ONLY!!
I've read that lots folks spent a lot of money on purchasing many different BT headsets and tried to get it work with iPhone 3G. I myself tried: Plantronics 510/815/855, Sony HBH-DS970/980, Nokia BH-903. None of them can work fine with my iPhone 3G ever! And iPhone 3G even cause BH-903 and DS-980 hang up after pairing or finishing call!!
That's why I don't believe it's just a "SPECIAL CASE". How could a product FOR BUSINESS purpose get this kind of basic function problem?
I hope we will find this issue could be resolved completely with new F/W, like Safari crash problem before. Other than this BT IOT problem, iPhone 3G is really the phone/companion could provide complete solution fulfill my personal and business needs.
