• Change audio resampling

  I'm on OS X 10.10.5 5.2.3 Motion...

  I'm trying out a credit simple roll sequence with music under him, but the audio keeps have resampled to 44.1 kHz (original audio is 48). My audio system interface is set to 48 kHz, which, according to movement records 5, means that the audio output should be 48 kHz.

  Am I missing something, or movement will always force resampling?

  Thank you!

  Open Utilitiles (from the Finder, select go > utilities or type command-shift-U).

  Open Audio MIDI Setup. Find your audio interface in the left column and select it. Check the source and output parameters. They are all two 48 kHz?

  Note: If you have checked the info summary Export, it can report the export audio as 44.1, but she must be recorded at 48 k (at least it was in my tests).

• Do I need other Anti-Aliasing before resampling

  Hi all

  Just thinking how this resampling works.

  Basically, it's just a standard resampling with dynamics of the frequency. This means he could the high frequency alias noise down in the region of interest.

  The analog inputs have smoothing filters that will filter the signals to (-3dB) 24.56 kHz who works for the IO module because the nyquist frequency is 25 kHz.

  However we then re - sample up to (for 50 Hz) rated 12.8 kHz. This means a nyquist of 6.4 kHz for everything from 6.4 to 24.56 kHz can alias downwards.

  This can be solved by introducing a digital filter in the FPGA with a better cut-off frequency (to handle variation so probably want a bandwidth of at least 7.04 kHz 55 Hz) but I've not seen this in any of the examples.

  Am I mistaken, or nobody ever bothered?

  See you soon,.

  Decided to take the experimental approach!

  Generated a wave of 50 Hz with a 5% 10 kHz imposed on this topic and it doesn't come through.

  Dig deeper into the resampling, there seems to be a FIR filter in it which I think is taking care of him.

  See you soon,.

• How the graph data are resampled pixels?

  A test, I created two identical graphs with land areas 500 pixels wide and a noisy sinusoidal signal of 1000 samples.  A chart displays the waveform right, while the other got the results of the use of the function Arrray to decimate to halve the number of samples.  They are not the same.

  Up to a waveform graph does exactly when it displays a data value larger than its width in pixels?

  

  As you have noticed, the graph is a little more intelligent that you expected.  When the number of points exceeds the number of pixels, a form any resampling must take place.  A simple decimation as you tried would eventually pass some interesting points.  Instead, the outliers receive priority when selecting which points to display.  Strong in this way, peaks and dips appear even on a large scale.  Reproduce this behavior yourself can be tricky.  And once you reduce the data set, the points are gone and zoom is not as effective.

  Usually, I try to let the chart to do as much as possible.  A simple and effective way to reduce the size of the data you have to ship on the network is to use the SGL precision instead of double precision.

• Vision Assistant has theAlgorithms.Resample feature

  I'm just not see it, or is there no way to resize (Resample) an image in Vision Assistant?

  It seems to me that the resizing of an image is one of the simplest function of image processing.

  I'm used to having to open images in MS Paint to resize, and then reoppen in the Vision Assistant.

  I created a VI resampling that works. But I just thought that it would be part of the core functionality.

  Yes, the function of resampling in Vision Assistant is in the first tab (processing of functions: Image). Select the step of geometry, and Resampling.

• Resample IMAQ generates the error-1074396157

  Hi all

  While he was trying to use IMAQ resample labview VI 2014, I get code error-1074396157, with the source of the error being "imaq resample. Everyone knows this? What is going on?

  Thank you

  Soheyl

  According to the help of LabVIEW, 1074396157 error code has the following possible reasons:

  IMAQ Vision: Unauthorized copying of Vision of NOR.

  The solution is to put the licensed software.  IMAQ and the Vision Development Module require an additional permission beyond LabVIEW base.

• resample behaving badly

  Why not resample.vi (in GIS proc. Toolbox, LV 8.6) sometimes make mistakes?

  VI attached gives error when input file = .txt and decimation factor (DF) = 6 hz sin0.10, attenuation = 40, BW = 0.25.

  Error-20076 occurred at NI_AALPro.lvlib:AAL resample (const to const) .vi:2 in NI_AALPro.lvlib:Resample (constant constant, single - channel) .vi:1 in decimation_test.vi.

  Possible reasons: analysis: the resample point cannot be calculated with the signal behind that of the entry.

  If an error occurs depends on the file entry (at least its length) and the value of DF, mitigation and BW.  Examples, with attenuation = 40, BW = 0.25 if it is not specified:

  Input file = sin0.10 hz .txt: error when DF = 6, 7, 8 (other DFs 1 to 10 OK)

  Input file = sin0.001hzlong.txt: error when DF = 6, 8, 9.

  Input file =, DF = 6: error when BW = 0.25, no error when BW = 0.35.

  resample.VI can be called with anti-aliasing turned on or off.  Errors seem to occur only when anti-aliasing is disabled.  The help says mitigation and BW settings affect how anti-aliasing is done.  So why the occurrence of errors depends on the values of the parameters that are supposed to be ignored when anti-aliasing is disabled?

  Is this a bug?  Thanks for your help.

  I think the first question again and check the code.

  Because bandwidth is 0.01, stopband is 0.5, then the transition group is dominant.  When the attenuation ranges from 50 to 100 dB, frequency response increase a little bit at the beginning and then abruptly down the transition Strip. And 0.01 Hz within the first part of the transition Strip, then the amplitude of output increases.

• IMAQ resample invalid image type

  Hello

  I'm rewriting an old non-versatile version of a VI. I don't have much experience but I have the old VI as a kind of model for what I do. It's weird, but even if I try to do things exactly the same way, they do not work.

  I acquire an image high resolution camera (IMAQ to acquire) which is too large (1280 x 1024). I want to resample (IMAQ resample) at 256x320px.

  I get the error message: error-1074396080 occurred in the type of IMAQ image resample not valid.

  The probe I put to read of the Src of the Image shows the image correctly and tells me that it is a 16-bit unsigned image. This should be a valid image type, right?

  No, not right. IMAQ resample does not support the type of U16 (at least until VDM2011). See help.

  Convert your image to I16 (if possible) before resampling.

• resample wave information

  Is there a way to re - sample vague information?

  I know that I can read a wave file to 11Khz and then write information to 22 kHz or 44 Khz.  But what I want to do is read in the file of 11 Khz, 22 Khz to upconvert, perform processing of the file, maybe combine it with other information and then read it or write.

  Of course, I want to go the other way, i.e. downconvert from 22 Khz to 11 Khz.  What would be great would be to have a version of write it Wave leader VI which returns the information in a table instead of save to disk. I guess I could write and then read it again but that seems inelegant to say the least.

  Any advice?

  I think what you're looking for is the Align attribute and resample express VI.

• First round with resampling of wave and the memory is full error

  Hi all

  I have a little problem with my VI that I don't understand.

  I'm doing a motor controller application that can take a random waveform and TTL signals for a motor controller.

  It's all good, but the first time I run VI I get a memory full error (see photo)... It is only the first time after I opened labview I get

  This error... Second time I have start the VI, it works as it should. I guess it's something to do with what kind of data it records in memory.

  Looks like it has something to do with the function resample, but exactly what I'm not sure...

  I hope some of you guys (or girls) are able to help me, thank you!

  Good day!

  Kind regards

• Resampling in Photoshop

  I have a picture that is 300 dpi, 2.5 in scale. I'm trying to re - sample the image to keep the width at 2.5 but to change the resolution to 72 dpi. I use this line of javascript:

  activeDocument.resizeImage (undefined, undefined, 72, ResampleMethod.BICUBIC);

  but the picture comes out as if the resample button was unchecked. The image is in 5,792 and the size of the file is identical to the original. No idea what is the problem?

  The pixels will be be resampled to maintain the width in of 300ppi in 72 dpi

  At the end of the day, it fits the image on-screen.

  app.preferences.rulerUnits = Units.INCHES;
  var ww = activeDocument.width.as('in');
  var hh = activeDocument.height.as('in');
  var ratio = hh/ww;
  activeDocument.resizeImage (new UnitValue(ww,'in'), undefined, 72, ResampleMethod.BICUBIC);
  // Optional: fit on Screen
  app.runMenuItem(app.stringIDToTypeID ("fitOnScreen"));
  

• Rendering of 1080 videos resemble 540 resampled or interlaced half frame.

  Hello

  Newbie to Premiere Pro.  Not a newbie to computers and to the media.

  
  I work mainly digital image and CG, very few video source, so this isn't a problem of interlaced/progressive source.
  Much of the content is 1920 x 1080 PNG images and sequential images PNG output 3ds Max etc.

  During the creation of new projects, the sequence is made up to 1920 x 1080, square pixels (1.0), no fields (Progressive Scan).

  Then export that I use AVI codec None so that it is uncompressed, Custom, also with 1920 x 1080 pixel square (1.0), number fields (Progressive Scan), 30 images/s, 24-bit, quality 100, use maximum render quality.

  Each video or exported output single PNG image resembles a was reduced to horizontal and then used and then resized 540 to 1080 resampled file up to 1080, or as a single field.

  See the image as an attachment.

  Top of page text comes from a source PNG, text background is what first exports on.

  The word "content" is 100%, the 'e' on the right are maximized to 400%.

  Any ideas?  What I am doing wrong?  This cannot be correct.

  

  I tried a few other formats, and it is apparently the AVI format exporter.
  I do not get the odd vertical resample artifacts with other formats, I tried just quickly.

  I chose this format of configuration as a result of googling 'Export Format uncompressed first Pro CC' and that's what all the results of the research, said to use, I guess they were wrong.

  So no one bothers not using the same settings as see you in my above post, they do not work properly.
  I'll have to spend some time to determine what other format will give me uncompressed exports or better.

  Thank you all.

  * EDIT *.

  The formats 'AVI (uncompressed)' v210 and the "Quicktime" Uncompressed UYVY, all the work without the vertical resample glitch.

  The (uncompressed) AVI UYVY will play in Windows Media Player.  AVI v210 and QT will not.

  The v210 AVI (uncompressed) and UYVY will play in VLC video player.  The QT interval is not.

  A basic example of the size of the file is, a source of k 1 095:

  -non compressed QT of 1 096 k

  -AVI (uncompressed) v210 is 973 k (v210 = 4:2:2 10-bit AFAIK)

  -the UYVY (uncompressed) AVI is 730 k (UYVY = 4:2:2 8-bit AFAIK)
  Visually, all three are very good.  I guess the mov QT is the closest source according to file size.

  For intermediate / archive files of clips that I decided also to try the QuickTime GoPro CineForm RGBA 4:4:4:4 12 bits per channel codec.
  See the Adobe page: GoPro CineForm codec support in Premiere Pro

• How to size of resampling and new photo of the lot?

  Hello

  I'm working on a magazine with more than 100 photos. Currently, these pictures come to me in need of resampling, change of size and mode changes. They all need to be the same size and good mode, so I thought I'd try lot of dealing with this. Can someone help me with this? (In need... TIA, so!)

  Hi US_IDeaS,

  You must create an Action to save all the changes you want to make on the image, once you did create the Action, then you apply this action to the batch and to apply the same effects on all Images.

• Does anyone know how 'an image resampling?

  A client gave me a file and said it was fine, except that one vintage photo needs to be resampled because the resolution is not high enough... Does anyone know how or where I could find a tutorial, etc.?

  Thank you for your help.

  Resampling is simply by changing the size (size in pixels) of an image. In photoshop, there are several methods of resampling. I guess you want to enlarge the image, in order to preserve the details could be better, but play with the different methods to see what works best. Keyboard shortcut is ctrl/cmd-alt/opt-i.

  

• When changing the size of the Image "pixels" is grayed out when I uncheck resample image

  I want to resize an image for the web and need to know the exact size image in pixels, but when I uncheck resample image to select pixels as size is grayed out. Y at - it a setting I need to adjust or change?

  It is supposed to be gray. Resample uncheck lock the pixel dimensions, so it cannot be changed.
