Audio distortion and clipping from imported AVCHD

I just built a new computer that works great for video and is now playing back AVCHD no problem.
The sound however, is the same as before. It sounds like really really bad over clipping, straight from the RAW imported video... Sounds fine on the camera and it sounds fine in my Sony Content Management Utility... But in premiere and sound booth... it's not working.
It was also the same problem on my other computer even though I had a $4000 AD/DA converter that can go up to 24bit 192khz and I'd used programs such as Nuendo and Cubase with no problem, even at 32-bit float... (Audio and Music is my primary)
Interesting thing is, this is also happening in Soundbooth
Ideas?
Problem existed on both:
Windows 7 and Windows XP Pro SP3

Got it! How did I not see think of this before!
Tried a different format on the Sony HXR-NX5U, Dolby Stereo. And it works.
What I was using before as a LPCM (L for Linear, it's a lossless codec) Codec format which I gues premiere does not like.
Adobe Premiere would probable recognize PCM because it is Non Linear Quantized and older format and it explains why LPCM was distorting - becuase it's on a wider linear scale that exceeds what Premiere supports - it was still seing the PCM part of the code but not that it was Linear.
The audio nerd prevails.
*edit*
Huh, well I don't see PCM nor LPCM in supported audio formats.

How to add handles on .mov clips from an AVCHD camera

Hi
I am trying to put transitions between the clips I have just logged and transferred from my AVCHD camera. They are imported as finite .mov files, without any in and out points. I know that I have to add handles to insert transitions. How do I change the in and out points? When I open the clip in the Viewer window and play with the little slider towards the bottom, it seems to change the overall length of the clip. Is this correct?
thanks!
Terri

Thanks. It does make them shorter. Next time I will do that from the start so there is less messing around on the timeline!

Extreme Audio Distortion and Loudness occurs randomly...

Extreme Audio Distortion and Loudness occurs randomly...when I open an old FCP project.
There seems to be no logic behind when it happens.
And the audio was fine the last time the project was saved...
Anyone know why this happens, I feel like I'm the only one who might have this issue

No you are not the only one.
Do a search in this forum.
But I haven't it seen reported for the last few months, so maybe this solved with some update.
If the search does no help you, you need to give us some more information about the specs of the audio/movie files, sequence settings etc. And on the versions of FCP OSX and Qicktime, as well as information about how the audio is coming from the speakers (internal audio, AJA or Blackmagic card, etc)

Distorting and clipping on burned CDs

I'm having problems with CDs that I've been burning. I've been making a lot of compilation CDs and haven't experienced problems before, but just recently I've noticed that a lot of the songs badly distort. These sound absolutely fine played from within itunes - it's when they are burned to a CD.
There is crackling, distortion and clipping at the top end which sounds horrible. I checked my itunes and the soundcheck and volume adjustment controls are disabled. The CD media is a good quality brand and the songs are ripped from CD (with error correction) or purchased from the iTMS.
iTunes is version 6.0.1 (3) with quicktime version 7.0.3. My mac is a revision B iMac G5 with a Matshita DVD-R UJ-845 superdrive (firmware rev DBN9). OS is 10.4.3
The song sources were in AIFF, mp3, apple lossless m4a and mpa and WAV formats. I checked the waveforms in Audacity for clipping but there was none in the original file. The CDs distort regardless of whether it's a cheap ghetto blaster, PC, Mac, stereo or home cinema system and the music ranges from hip-hop, dance and jazz to classical and acoustic. This seems to make no difference to the likelihood of distortion.
I've only noticed this problem going back to November.
G5 Dual 2.5

I am also having the same prob. I noticed though that
if I playback the burned CDs in my car, it sounds
okey. The ones I just burned from iTunes, if I play
it back within iTunes - they all have weird
distortions. So I guess it's a software bug not
hardware . . . then again, it could also be my
Superdrive . . .

I was having the same problems, noise, noise and more noise right after I upgraded to iTunes 6. I checked in with my Mac consultant and she suggested I try repairing permissions. I did that and have had no problems since. I thought it was hardware based also, but I was wrong!
Here's what she sent me:
Here's how to repair permissions:
Open Applications > Utilities > Terminal
type this command:
sudo diskutil repairPermissions /
make sure there is a space before that slash
It will ask for your admin password
Good luck.

Ipod distorting and clipping

I have a 5G ipod. Brand new. Don’t have EQ on. Don’t have Sound Check on. I notice a lot of clipping and distortion. It’s not my headphones. Happens for low end guitars/bass, or high voice or horns. Is this a problem typical with the ipod? Can it be fixed? Is my ipod defective? I’m now to these mp3 players and think they’r great other than the distorting and clipping.

oops, posted this in the wrong fourm.

Thunderbolt audio distortion and slow Pegasus Raid Speeds

Having major problems with my MBP 17" and my thunderbolt set up. (MBP 17" 2.3 i7 quad core, (2) 27" thunderbolt displays, Pegasus R6 12TB Raid, Blackmagic Ultra Studio Pro 3D)
Apple states this clearly on there website that it is possible with this exact set up.
Issues: With all 4 devices plugged in the Raid speed goes from about 515mb/sec write to 166mb/sec write speed.
With one thunderbolt display, raid, and blackmagic I get around 460mb/sec. As soon as the second display is added to the mix the speed drops off considerably.
After Effects and Davinci Resolve color correction software cannot get sync on the Blackmagic box. Final Cut works ok.
The other really big problem is that when you do any kind of data transfer across the thunderbolt line, I cant get audio to play back for more than a few seconds. I get distortion and static in the line. I have tried the thunderbolt audio from the monitors and the Blackmagic box.
The most curious thing is that it all works on the 13" MBP. The write speed goes to 225mb/sec with everything plugged in, however it must be enough, because the audio doesnt distort and I can get sync on my color correction monitor out of the Blackmagic box.
I also tried a brand new 17" MBP 2.5 i7. I still get the same problem. It is like there is something wrong with the 17".
I have contacted Pegasus and Blackmagic. Pegasus said that they now know about it and are working with Apple.
Does anyone else have this set up and are you experiencing the same problems? Please feel free to respond with any questions. I wouldl love to hear from Apple regarding this matter. Seems like a big problem.
(other items testing)
-Switched video card to not auto switch. just use high performance.
-Went to Apple, bought a brand new 17" 2.5, stock. tested it. same exact results.
-Moved all the items around in the daisy chain to see if one item has to be first. No luck.
-Laptop monitor open and closed, same result.
-Reinstall OS.
-Brand new motherboard.
-New hard drive
-New RAM
No luck again.

This is not a surprise. Apple's software RAID is slow. The best option for using Apple's software RAID is to use a regular disk for your audio files and keep the backup copy on a RAID. Also, depending on how important those files are, you might also want to keep an off-site backup copy because fires, floods, and thefts do occur.

Audio component not apearing when importing AVCHD .MTS files

When importing AVCHD .MTS files into Premiere Pro the Audio component is not available (also in After Effects and Media Encoder)
What am I doing wrong :/

You could most likely convert them using a program like 5DTORGB, and then pull them back into Premiere. Although there is a chance this won't work, however in most cases I find it usually does work. Just be prepared to lose your metadata.
If your on a PC I'd recommend downloading their beta version it will allow you to transcode your AVCHD to ProRes HQ.
http://rarevision.com/5dtorgb/
All you have to is provide them a correct email address and they'll send you a download link. When you transcode though keep in mind that it's going to make your file sizes much much larger, however this because ProRes is much less compressed than AVCHD video is. You do need to keep in mind though that ProRes HQ is visually lossless. If you chose to use another free converter program you'll most likely get stuck chosing a lossy format. Another nice thing though, is that it works on MAC too. Your shooter needs to know not to do this again though, because as you already know at this point. It can cause big issues...

I need to copy audio files and projects from logic to an external hard as my MBPis nearly full and my external hard drive has packed up with all my files on it, any suggestions on how do I copy 200GB from my MBP to a new external HD

I Use logic and back my audio file and projects on an external HD ,this has now packed up . I have all the files in the MBP , but need to copy them to a new external HD, I have only 10GB left on my machine , how do I copy 200GB from my machine to a new External HD.
any helpful full advice would be appreciated.

Yes, just drag and drop them into the drive..
How long will it take? Hard to say without knowing the type and speed of the drives in question.. and even then it's hard to estimate... but does time really matter?
The fact you only have 10 Gigs left will/may slow the process down but it wont/shouldn't stop it...
If needed.. just drag and drop some of the files at a time.. not all of them.
Remember that copying files doesn't delete them from the original drive... You will still need to delete them yourself after they are copied over and empty the trash....
However....
When you saved these projects in Logic (Pro X?) did you save them using the include audio files option?
If not, then when you move the audio files used in these projects... Logic will not know where they are to reload them........ and that will cause you issues.
So.. if you didn't...
I would use this method instead...

Captivate 8 Audio delay and clipping

So I have started recording audio directly into Cap 8 slides just as I have done in previous versions. But this time I am noticing that the audio seems to be "delayed" at the start and "clipped" at the end. So if I record something that is 2 seconds, It doesn't start until about .5 seconds in and the end of the audio which is silence has been clipped for me. Even if I go in and put in a 1 second of silence on the end of the audio and save it when I come back it it is gone.
Does anyone know what is happening? Thanks!

While I can't explain the delayed start, Captivate seems to have always "helpfully" removed silence at the beginning or the end of a clip.
When recording, it's helpful to record a couple of seconds of "room noise" or "white noise" before speaking. This gives you a bit of waveform to play with. You are then able to select some of it and paste it elsewhere. Perhaps at the end to pad it out.
Cheers... Rick

T410 Bluetooth audio distorted and delayed

Hi everyone, When I connect my laptop to my speakers through bluetooth, the audio gets distorted (the pitch is unusually low) and delayed. I have a ThinkPad Bluetooth 2.1 with enhanced data rate II, and the operating system is Windows 7. I have installed the latest drivers and the speakers work well with bluetooth when connected to other devices. Has anyone got an idea what this could be and how it could be solved? Best,Lambj

I am having a similar problem when using my Motrola S305 bluetooth headphones to listen to music files. The audio is garbled/distorted and I can't seem to adjust by lowering volume (either on the BB or the headphones). Phone call audio through the headphones is perfect, and the music audio is pretty good through the BB's speaker. It's odd, but I didn't have this problem on the Tour 9630 (using the same Motorola headphones).
Has anybody had similar problems with the Motrola S305 headphones? I did not see it on RIM's list of "compatible" headphones. Maybe these issues can be addressed with an OS update?

Dropping audio when dragging clip from Source Panel to Timeline

Distortion and crash after importing images in Adobe Premiere 6 Pro

I am very happy with Adobe CS6. On thing though has prevented me from being able to finish my edits in Adobe Premiere Pro.
When I import pictures into the project, there it is: a shaky horizontal 'ribbon of distortion', which makes it imposible to view or work in Premiere. After Minimalizing Premiere, the ribbon sometimes shows up over my other applications, f.i. firefox. I wanted to share a picture of this And now the weird thing: I cannot make a screenshot of this. After pasting a printscreen into paint, the distortion is gone. So I took my phone, check out the video below.
My system:
- Dell Inspiron M5110
- AMD A8-3520M APU
- Radeon HD Graphics, 1.60 ghz
- 8 GB RAM
- 64 bit operating system
I hope you could shed a light on this error.
Thanks a lot!

Thanks. I have installed AMD Catalyst in order to assess my system's problems and outdated drivers. Maybe here is a problem? I have changed my laptop's harddisk into a SSD 9 months ago and thereby had to manually install all drivers again. Still, I am puzzled what to do now. And how.

Unrendered Audio - sequence and clip settings are the same

When I drag a clip to the timeline a redline appears on the top of the timeline. I know this means that there is a setting issue between the sequence and the clips. All the settings are the same with the exception of the:
audio format - Clip: 8 bit integer
Seq: 32 Bit Floating
Audio Rate - Clip: 48000 5kh
Seq: 48.0 KH
The clips which is 1 1/2 HR takes 6 minutes to render.
Does anyone know why I need to render this clip?
Macbook Pro Mac OS X (10.4.8)

Here: a foolproof way to ensure clip-sequence settings match up:

And if you still have the problem, why not convert it to AIFF via QT?
