Distorted Camera Output

Hello there. I will work on a project about Real-Time Vision via Labview. When I've tried to test my cam at NI MAX(nimaxscreenshot.jpg) everything is okay. But when I try to test my cam via simple test vi(blockdiagram.jpg) my cam output(frontpanel.jpg) is distorted. My camera is Basler Pylon acA2500-14gc. What is the problem?

Actually I am new to image processing at Labview so I don't have knowledge about this toolkit. The blockdiagram that I used is from a Youtube video. Now I used this blockdiagram(block2) and result is same distorted output.

Why distortion when output through computer out but not audio interface out?

Equipment:
Focusrite Saffire Pro 24 digital audio interface
2.5 GHz Intel Core i5 Mac Mini with 4 GB 1600 MHz DDR3
Software:
OS 10.8.2
Mainstage 2.2.2 32 bit
I'm running a mic into my digital audio interface, which connects via Firewire to my computer. The mic input is mapped to an audio channel strip. When I attempt to run sound out using the stereo out on my computer, it works okay for about 10 seconds, but then starts progressively becoming more distorted. At first, I thought it might be a bit rate issue, so I dropped it down very low. This corrected it momentarily, but, again, after about 10 seconds, the distortion came back. When I change the output to one of the audio outs on my digital audio interface though, it works fine. However, I don't have the Y cable I'd need to take 2 of the mono audio outs on that device and merge them into a stereo out that I could plug into my computer speakers (that's all I've got right now), so I'm stuck with mono out. Do you know why I'm getting this distortion on my computer's line out? I don't have audio distortion problems if I'm watching Hulu or anything, and my Saffire drivers appear to be up-to-date and Focusrite says the device is supposed to be compatible with Mountain Lion. Help is much appreciated!

Video camera output (i.Link or Firewire) to connect to my MacBook Air USB input

Is there a way to for my video camera output (i.Link or Firewire) to connect to my MacBook Air USB input??? Is there any kind of adapter?? I have many movies I want to edit on my Mac

I don't believe firewire to usb adapters exist.
Which MacBook Air do you have? If you have the 2011 model with Thunderbolt, then, you are in luck.
Thunderbolt to firewire adaptors will be available.

MuVo V100 suddenly distorts sound output, hates vocalists

9MuVo V00 suddenly distorts sound output, hates vocalists Greetings. I have a MuVo V00, which until quite recently has worked according to specifications as desired. After a period of nonuse, upon reinstatement it showed a global distortion in sound output, resulting in--impressi'vely--vocal frequency-range portions of files to be suppressed. Never mind that some music was improved in this way--it is an error that needs rectification, and unfortunately MuVo V00 models are past the End of Service Life.
I have downloaded the firmware patcher, and reapplied the latest firmware (which I had already had on the device, but consensus in various problem threads here leads one to believe that refreshing the firmware is a borderline panacea). No good. Swapped batteries on a hunch, no good. Swapped headphones, no good. Checked the files that are actually on the disk, they sound like they ought when played through the computer's means. I'm low on ideas, and the last person who asked this question here did not receive a reply. Anything spring to mind?

T400 2765 T6u, vista 32b distorting audio output on my videos

My T400 has poor visual quality in pictures and videos one week ago. After I updated the graphic driver, the images of the pics and videos are ok now, but the laptop is giving out distorting audio output on my videos. Can someone help me out with this issue?
Thanks,

Solved!
Go to Solution.

I updated my audio driver and bought another headphone and solved the problem. I don't don't know why my previous headphone doesn't work for t400--it works perfect for my desktop.

This new 1080p tv sets and my 1080i Sony camera-output from FCP

I use a Sony FX1. My best capture is at 1080i or 720p.
I've recently been recording at a higher shutter speed and am getting improved footage.
I note that FCP has an output option of 1080p - 30. Is this only half as good as the new monitors can show? If I eventually want to create highest quality for playback on 1080p-60 will I need an updated camera and will FCP have to offer 1080p-60?
Since I've never viewed 1080p-60 is the - 30 vs - 60 a big issue?
Using the 1080p-30 makes for a much improved view than H264 720x480 or HDV 1080i any other settings up to this one. H264 is a GREAT file size saver but does not use near the bit rate of 1080p-30.
One other thing. When the new OS comes out with 64-bit processing, is FCP and DVDPro already ready. I have not found any specs on FCP 5.1.4 indicating it is 64-bit ready.

ensure the following are set
View>Video Playback>Firewire Apple 720x480 (NTSC or PAL - whatever is appropriate)
View>Audio Playback>Audio follows video
View>External Video>All Frames
If this isn't what you are set to do, you won't be sending video out to your recorder.

AppleTV distorts sound, output level too high

Hi
I have a problem and have already tried a number of solutions.
My AppleTV sound is distorted, due to the output level being too high. Initially I used the TVs headset jack-connector for connecting to my amp, and lowering the output level from the TV didn't work. It is distorted from the source (AppleTV)
Now I have bought a seperate D/A converter for connecting the AppleTVs optical output directly to my analog amplifier. Still doesn't work. Sound still distorted.
When playing music through AppleTV, I have the ability to adjust the volume level on the source device. And then everything is OK.
But airplaying video/youtube from my ipad (I do that a lot - playing kiddie-flics for my toddler) there is no option to reduce the sound level.
Effectively most content airplayed will be distorted - and I am sick of it. I have a high-end amp and speakers. I do not expect audiophile quality from the AppleTV. Still I didn't expect defective/destroyed sound... And no, the AMP isn't the issue, as this has been replaced as well, due to an upgrade. Same issue on both AMPs.
Any good suggestions? Or should I simply accept that the design criterias for the AppleTV doesn't involve a reasonable audio quality? Or is my particular product defective?
Thanks,
Claus

If the audio is clipped there's not much you can do other than re-record. But there is this: http://www.izotope.com/products/audio/RX/

SX20 main cam output on monitor 1 and monitor 2 at the same time

Hi Community,
we have an SX20 (TC7.0.2) and need to have the main source (12x Cisco cam) on both monitor outputs, because we need to record the VC session.
DD option is installed. Is there a way to get this configured ?
Regards
Jens

If you just want to record what the SX20 sends out to its main monitor to a second screen/recorder, you could just use something like a DA2 to duplicate the audio/video that is played locally.
In addition to what Patrick has said about the video from the local camera though - you're also not going to get the local audio through the monitor output - only the far end - so, again, this may not be what you're wanting if you're looking to record the whole video conference (audio and video from both ends).
I suggest you look in to the Cisco TelePresence Content Server product if you're looking to do recording on a regular basis.

Want to set my camera output 16bit greyscale

Hi All,
I am using a Guppy pro F-031b camera.
I want to let it output 16bits greyscale picture, so
1st .I set my camera as Format_7 Mode_6(partial image and mono 16) by writing the register.
2nd .Then I set the IMAQ image type as grayscale(U16).
But I still got a 8bit picture. What shall I do to solve this problem?
This is the first time I work with Labview. Any help is appreciate.
Thank you,
Best,
Wen

Hello Plarq,
Two things:
1. Wire the "Image Name" terminal of the "IMAQ create.vi" to the "Session In" terminal of the "IMAQdx open camera.vi" (This is not related to your question, but it is a better practice).
2. Now, in regards to your issue, check the following article which I hope can be helpful:
"Can the NI-IMAQ and NI-IMAQdx driver acquire true U16 images?"

Video distortion when outputting to QT

I am running FCP 7.0.3 on a Macbook Pro. I am editing a sequence that is 1 hour and 48 minutes. The first image is text over a field of black, the second is a tif of a logo, and the third is video. When i try to Export a QT video using FILE / EXPORT / QUICKTIME MOVIE / 'Current Settings," when it gets to the video, there is a field of green, then some pixilated video distortion, then the video seems to flicker back and forth and go back a few frames like a stuck record. I notice that sometimes when I am playing the clip in my timeline, it tends to get a little bit "stuck" when it goes from the tif to the video. It seems to jump a few frames ahead, but there is no video distortion, that only shows up when i expert the entire video. I have also broken up the sequence in to shorter clips of about 15 minutes and the problem seems to go away. Any insight greatly appreciated.

When you converted the files in Clipwrap, what settings did you use?
If you intend to work in FCP-7, then ProRes:
Pierre Degaillande1 wrote:
Is there another workaround that will take less time?
Not that I am aware of*. H.264 is problematic in FCP7. You either convert the footage to an FCP edit friendly format prior to editing, or you end up in your situation and do so on the timeline.
I am using a Sony HXR-NX5U camera shooting at 1080i at 30fps,
Do you mean 1080i at 29.97 fps?
* If you still have the files that are 15 minute subsections of the full clip, use QuickTime 7 to copy and paste them together into a complete file, and save that file. In QT7, Open the all the subclips as separate QTs, then in the second movie, select the entire movie, copy it, and then go to the first movie and move the playhead to the end of the clip and the paste the copied 2nd movie into the first. Repeat as necessary. No guarantees.

Distortion at Output

I used one of the examples in Labview and also used one of the vi generation. I'm getting distortion for sawtooth and square wave outputs, when I increase my frequecy to more than 1000Hz.

Ahmed,
We talked a couple of days ago over the phone. In our conversation we discussed your application and the signals that you want to generate with your PCI 4452 DSA board.
You are trying to generate several sharp edge signals, like square waves, triangle waves, sawtooth waves, etc. We tried to generate square waves of different frequencies and what you were seeing was the following:
- When generating a 5 kHz square wave, it looked very good in your oscilloscope.
- When generating a 8 kHz square wave, you began to see a resemblance to a sine wave.
- Finally, when generating square waves with a frequency higher than 13 kHz, your signal would look exactly as a sine wave.
So why does this happen?
First it is necessary to understand a little more about the hardware architecture of your DSA board. The PCI 4451 board uses Delta-Sigma technology for analog output (Digital-to-Analog Converter - DAC)as well as analog input (Analog-to-Digital Converter - ADC). The Delta-Sigma converters provide excellent linearity and automatic filtering of frequencies above the Nyquist limit. The Delta-Sigma DAC oversamples and interpolates between points in the data array to "smooth" the signal and remove any components above the Nyquist frequency.
Your DSA board has a Delta-Sigma DAC with an update rate equal to 51.2 kSamples/s. This means that the Nyquist frequency of your signal is aproximately 25kHz, so the maximum frequency of sine waves that you could generate is aproximately 25kHz.
So far we know that the maximum frequency of a sine wave that can be generated with the PCI-4451 is aproximately 25kHz, and that the Delta-Sigma DAC will interpolate between points to "smooth" the signal being generated and remove any frequnecy components above the Nyqsuit frequency. But why can I generate a 25kHz sine wave, but not a 25kHz square wave?
All complex periodic waveforms are composed of a harmonic series of waveforms. This means that square waves, triangle waves, sawtooth waves, etc are the result of addition of a fundamental sine wave and its harmonics.
A square wave is built by adding a fundamental sine wave and its odd harmonics. Each new wave flattens the top of the original sine wave by pushing up valleys and pulling down peaks , causing steeper sides. The more harmonics added, the better the square wave being generated (see image attached below).
So the more harmonics included withint he 25kHz frequency limit, the better quality of the square wave.
If you generate a 1 kHz square wave, you will see in your oscilloscope a pretty good quality square wave signal because odd harmonics up to 13 harmonics are included within the 25kHz range.
If you generate a 5 kHz suqare wave, 2 harmonics are included within the 25kHz range. For 8 kHz only 1 harmonic is included in this range, and that is why you begin to see a resemblance with a sine wave. Finally, for frequencies above 13 kHz, only the fundamental frequency is present after the Delta-Sigma DAC removes all frequencies above the Nyquist frequency, and that is why you see a sine wave as the output.
Hope this helps. Please feel free to contact me if you need any further assistance.

16:9 aspect ratio distorts in output

Please help, I am on a tight deadline!
I normally work in only 4:3 aspect ratio. I had to import and use all 16:9 footage today, so I created a new project, highlighted sequence, clicked "Sequence - Settings - and check marked the 16:9 anamorphic square". Canvas changed shape and fit the footage perfectly.
Went to export the file and it keeps squishing the footage so that it appears to be 4:3 ratio and people are skinny and tall with distortion when file is opened.
It is a 9 minute slideshow, so I was just using it in iDVD instead of normal DVD Studio Pro. I made sure iDVD settings were 16:9, but it appears to be the same problem no matter what I change in export setting.
Any ideas how to fix? I need to give this to a bride ASAP. This has to be an easy fix that I'm simply overlooking. Thanks!!!

Thank you,
I take it that QT Player Pro will work with FCP, and not give it problems working together? Is this a reputable free download?

I use a dns server by which I remotely monitor security cameras. Whilst I can log on to the site I can no longer see the camera output since upgading to FF4. Chrome still works.Think I've tried everything obvious - any ideas ?

The frame of the video console is visible but there is no actual video. I've set the user & password to "admin" so someone could take a look if they get the opportunity. Thanks for your help.
MAF

Hello, yes it did & still does work on FF3. It also still works in chrome. I have to profess that I'm uncertain what the plug-in does or whether it is correctly spelled ? I can say though that I could also view the cameras through FF3 on kubuntu. Sorry if this is not very helpful.

Airplay camera output to ATV?

basically, is this possible?
I don't have an iPhone or the iTouch with camera, but I am interested to know if the camera in either can be streamed live to the ATV using, I imagine, Airplay.

There's all sorts of videos on Youtube showing you how to do this...

Imac DV G3 (PPC) speakers suddenly distorted sound output

HI everyone, I just bought an old iMac DV running OS9, and it worked just fine for a few days then - for no reason whatsoever, the stereo speakers suddenly produce very distorted sound, even at low volume. At higher volumes you can even see the speaker cones vibrating.
When it happened, I was just installing a few things with the volume set low, and the alerts suddenly sounded very distorted and remain that way. I didn't blow the speakers by playing loud music or anything like that.
I had nothing to lose, so I reformatted/installed new system but the problem remains.
My guess is that this is an electrical/hardware problem just down to plain old age, perhaps a bad solder joint or something. It's not the end of the world but it just seems strange that it happened so abruptly I did not move or thump the computer in any way.
It's an iMac DV from 1999, given it's age I'm not expecting miracles, but just wondering if anyone else ever had a similar problem and managed to fix it without pulling the computer apart and replacing a hardware component which is way too much hassle!
Were these models' speakers ever known to suddenly crap out with no warning?? Some older macs had design flaws they became notorious for (I'm thinking of my Ti Powerbook G4 hinges, I had that once!)
Is that extra button on the side booting into open firmware of any use? Just a stab in the dark!!!!
Any ideas/insight anyone?
Thanks!!!

At higher volumes you can even see the speaker cones vibrating.
That is normal. If they don't move, they don't work.
However, it could be that someone else overloaded the speakers and caused them to fail. I think the first step is to see if the speakers have been damaged. Use a pair of external speakers or headphones and test the sound.
Failed speakers in G3 iMacs are not a wide probelm like the one you mentioned, or bad capacitors in eMacs. Generally, the failure mode is the passive cooling (read, "no cooling") system baking the PAV board until some part of it fails.
