[newbie] Video import from analog input

Hi all,
Is there some device where we can import at higher resolution from analog input?

I'm having trouble with video imported from my camera memory card.

I'm having trouble with video imported from my camera memory card.The video breaks up and pixelizes when it's directly imported from the memory card. That makes the video useless. Why does this happen? It doesn't do that in any other video editing software. Thanks for the help.

More info please:
Type of camera?
Was the card formatted in the camera doing the shooting?
Type of files the camera is set to record?

How to get signal from analog input and send it to analog output (real-time)

Hi everyone,
I am doing simple task in Visual C++ and I am using PCI-6221(37 pin).
Basically, I want to send same signal from 'analog input' to 'analog output'
at the same time (almost), to make it real-time application.
Can someone please provide me sample program.
I would appreciate if you could provide me with the good tutorial which explains
step by step everything about programing NI-DAQmx for C/C++.
Best Regards,
Khassan
Solved!
Go to Solution.

This is my code in C++, you can optimize it if it looks too messy. This code reads signal from analog input and outputs it through analog output.
To make this code work additional include directories and library directories must be added from NI.
I hope it helps someone.

How to read data from analog input and export it to a file using Components Works

I've made a simple application (Delphi 5 using the activeX) that read data from analog input channel 0. After I read the data, I want to export it to a file using the Components Works on a 6035E NIDAQ. (I'm not using labview and don't want to use it)
How can I do that???
Regards,
Francis

Here's a sample code to do this...
P.S.: If you read only one channel this code won't work.
function MyFunction: Integer;
var
Low, High, i, j, ChannelCount, RowCount: Integer;
Po: P;
begin
//you are reading multiple channel
ChannelCount := VarArrayHighBound(Buffer, 1);
RowCount := VarArrayHighBound(Buffer, 2);
for i := 0 to ChannelCount do begin
for j := 0 to RowCount do begin
WriteToDisk(Buffer[i, j]));
end;
end;
end;

How do I get video imported from an iphone not recorded horizontally to look non-distorted?

How do I get video imported from an iphone not recorded horizontally to look non-distorted in imovie? thanks

You can't edit a video out of iTunes.
You would have to edit the video from the original film, either on your computer, or iPhone.

How do I email video imported from camera?

How do I email video imported from digital camera? It is a short video not more than a couple minutes long. I am using a PowerBook G4.
Thanks for any help.

BGreg wrote:
Video's get big quickly, however, assuming it's not too big, just attach it to your email and send it along.
This isn't a reliable method because you just don't know what the limits are on both ends. It is much more reliable to use a free file transfer service like Dropbox, Box, Google Drive, Amazon Cloud Drive, YouTube, etc and just send an email link.
Eustace Mendis wrote:
You should compress the video file before transferring. Just click on the name video file and go to the File menu. Compress ... is there. The compressed file will have the same name as the original, with a .zip suffix.
That's not the way to compress a video file. Video files are already compressed using lossy codecs like H.264, and if you apply a lossless codec like ZIP you may end up with zero additional compression. In some cases, applying ZIP to a lossy compressed file may cause the file to become larger.
The correct way to compress a video is to export it from iMovie (or whatever) with the correct settings for the destination (email, YouTube, iPad, etc.).

Video import from PAL camcorder

I have just bought a Canopus ADVC110 which converts analog video to digital and have it hooked into my Powerbook Pro via a firewire lead.
I have my analog PAL camcorder tied into the canopus and am attempting to import some PAL video but not getting very far.
I fire up iMovie and it does indeed detect the camera but when I create a new project it appears as DV-NTSC and not DV-PAL. I have changed the 'New Project frame rate' preference from 29.97 to 25 but still no good. When I click on Import I get the video/audio but the video is VERY jumpy and in black and white and the audio is totally garbled. As the video is PAL and the project says DV-NTSC this might be the issue? I would have thought that the Canopus would remove any PAL/NTSC issues as it is being converted to digital anyway? I don't know how to change the new project from DV-NTSC to DV-PAL, again I thought switching frame rate to 25 would have done this?
So, can anyone help me get a smooth video import onto the Apple? I dont care what resulting file format is as long as I can import and play it. I don't mind buying a different video application if necessary and do have Toast Titanium if that helps.
Many thanks,

It sounds like you may not have set the dip switches of the Canopus correctly to PAL.
See page 16 of instruction manual for the canopus ADVC110!
(I use the same one)

Lightroom: Capture time for videos imported from iphoto is not showing in metadata

Hi, I imported all my photos and videos from iphoto to Lightroom recently using the iphoto import plugin. I think all my photos were imported but I noticed that all my videos have no capture time, so they became grouped together in my collections. But I think I can still see their capture time in the "grey text" in each photo. Why did this happen and how do I resolve this issue? I really want my capture times to be in the video metadata and also want to see my videos in the right chronological order with my videos. Strangely, videos imported into Lightroom directly from my camera SD card do not have this issue, only the ones imported from iphoto do. Thanks!

LR does not properly handle video metadata in general, and in particular it often botches capture time. Sometimes this works: Select one video, do Metadata > Edit Capture Time, and then click Change All (without actually changing Corrected Time). If that sets the capture time to the correct time, then you can select all the problem videos, do Metadata > Edit Capture Time, and click Change All. If you have a small number of videos, you can manually correct the capture time using Edit Capture Time.
Please see this thread in the official Adobe feedback forum for more details, vote on it, and add your opinion: Lightroom: Metadata applied to videos in Lightroom isn't available in other applications

Video Import from a homemade CD

Greetings:
OS: 10.4.11
iMovieHD 6.0.3
Homemade Video files to import: .BUP, .IFO and .VOB's
Problem(s)
1. Operator Ignorance, inexperience and general thickheadedness
2. Would like to import a handful of video files from a CD to an iMovie production. Seems my trusty MacBook can't 'parse' these files. I have searched several purchased manuals but apparently don't know the keywords to unlock the process.
Thanks so much for your help! I stand ready to add you to my Christmas list!
Fentible–Tidy as you go!

You will also need the Apple Quicktime MPEG2 component for MPEG Streamclip to work.
A simpler solution is DVDxDV. It will convert the VOB files to editable DV for $25 complete.
Good luck.

Labviewcode wanted to count pulses from analog input

Can somebody help me with the following problem?
I don't have a Data Aquisition board so I use my steppermotor controller, the MID-7604, and it's analog input to read from a
sensor (photointerrupter) which outputs 0 or +5 Volts. I want to count how many times an output of 5 Volts appears.
The problem is that the signal is not a Waveform, so the Daq functions in Labview won't work. I've tried to generate a waveform
from the signal but also no results.
What I have created now is a counter which counts every signal above an adjusted value. The problem is that it counts on and on
when the signal is above the value, I want it to count one time. (like a trigger which detect a low to high level signal)
In the attachment you see that program and an other I've found (event counter) doing what I want, but I haven't been able to transform it in to
my own problem. Please help me on this because I'm stuck right now.
Thanks in advance

Hi,
there are some ways - one is using a shift-register.
Attached is a flank detector - each time "Boolean" changes from 0 to 1 or 1 to 0 the count is increased by one.
I hope that helps

OnComplet for video imported from url

i made an ios app.
in the app i have a video imporeted from url using StageWebView.
how do i remove the video from stage on complete?
the viseo is in second frame.
can i force the on Complete to remove + goto 1 frame again?

Thanks Sue, I was afraid of that!
The section of GB help on adding URLs says you can view via iTunes or DVD, and launch the website by clicking the link, hence my confusion.
It's a shame, because that would be a great feature in making sales or marketing DVD's - any idea why the disconnect, and do you know if Apple plans to add that feature?
Thanks again!

How to trigger from analog input channel

I am using a BNC-2110 into a 6062E card. And I am sure this question has been posted several times but I was unable to find a clear answer. I am trying to use the devices ai0 channel as my trigger source. I tried using a voltage source in the trigger reference, and that almost works but it only works for several loops before coming up with an error. If someone knows what I may be possiblely doing wrong or where to find this information, any assistance would be great.
- there is always an easy way, but it is always the hardest to find

Hey Henry,
The BNC-2110 is just the connector block. What card do you have the is interfacing this block with your computer? (should be a PCI or PCI-express card). Are the GPS receivers outputting digital signals that conform to TTL compatible logic levels (are the signals 5V or 0V with no more than 1.6mA of current)? If they are outputting a digital signal, then you can send these signals into any of the PFI lines to act as a trigger (or to the trigger lines).
For example, if you would like to perform an analog acquisition each time the trigger hits and have an X series card, you can open up example finder (help»find examples...) and then open Hardware Input and Output»DAQmx»Analog Measurements»Voltage»Cont Acq&Graph Voltage-Int Clk-Retriggerable.vi. Then make sure your Trigger Source parameter is set to the same PFI line that you are sending your GPS signal to (on the BNC-2110, the trigger connections are really just PFI0 and PFI12, but these are common lines to use for triggers, but any PFI line will work). If you have an M series card, and cannot do retriggerable analog input, you can reference this example for how to use counters to workaround this limitation of our M series cards: https://decibel.ni.com/content/docs/DOC-6801
If your GPS signal isn't digital, and is some arbitrary analog square wave, you can use an example like this: https://decibel.ni.com/content/docs/DOC-4657 to use the analog value to trigger you're reading (you just need to set the appropriate window for your analog signal in the VI). I hope this helps!

Video imported from camcorder loses synchronization

I have video shot on a Panasonic DVC-30 several years ago. In the past I was able to import it into FCP 7 without difficulty. I need to re-import the video for a new project. I am ble to readily import this footage into FCP X 10.0.4 but there is a progressive loss of synchronization between the video and audio on playback. The same video footage is easily imported into iMovie 7.1.4 with no synchronization issues.
What might be the problem and how can I rectify this issue?
Thanks.
John

Steve,
You have been very helpful so far, thank you.
Converting the footage worked, although I'm not sure this is the process I will always want to go through. I had to download a program called WINX HD Video Converter. I converted from avi to mov and it still didn't work. I converted from avi to mpeg4 and it worked. there was no option to convert to m2t.
Do I need a program like this to convert? I have the free trial now and don't want to pay until I know it's the right program.
First, I tried updating the settings I was shooting with but that didn't work. I shot at Full HD, 1080i and setup my project the same but the footage was still very choppy.
So... Adobe Premiere does not like avi files? Should I just get a different camera that is more compatible?
I also thought I could use this camera to digitize VHS footage but it doesn't accept input, shouldn't a digital video camera be able to accept input as well?

Importing from analog VHS-C camcorder to iMovie

I'm using a Panasonic PV-L552DH analog VHS-C camcorder (it's several years old) plugged into a Pinnacle Studio Movie Box. The sales person at the store said that iMovie on my iMac G5 would recognize the camera without loading any additional software (the Pinnacle device only has Windows software). Is there any way to import analog videos from my Panasonic PV-L552DH analog VHS-C camcorder?
I followed all of the instructions on the various help pages but it won't work with my iMac G5.
iMac G5 Mac OS X (10.4.8)

Joe, it looks like maybe you could kill 2 birds with one stone here. I had the same problem a year ago or so. I decided to buy a new Canon ZR200 camcorder that uses MiniDV tapes. But, the beauty here is that along with the camera being, well, a camera, it also can be used as a pass-through to convert old analog tapes from either an 8mm, VHS, or VHS-C camera. Just take the a/v cables out from the older camcorder, send them to the a/v port on the ZR200, and take the firewire cable from the ZR200 and send it to the firewire port on your mac. I do it all of the time, works flawlessly. Very simple. Costs about $250 for the camera, would probably cost you about $150-$200 for a converter only.

Video imported from iPhone 4 to iPhoto cuts out

I had a video I took on my iPhone 4 and watched it several times on the phone and it was fine... Accidentally imported it with some photos and selected delete from phone because I thought it was just the pics... Now when I view the video in iPhoto the audio continues just fine but the picture stops and picks up then stops and picks up again. I tried exporting it and it does the same thing... I have 2 questions,
1) is there anything I can do to fix the video on my computer
2) is there any possible way to recover the deleted originals from my phone??
TIA!

ok, update, I put the videos in an album I sync with my iPhone which put it back on my phone and it plays perfect?? I have viewed the movie in iPhoto, iMovie and just straight Quicktime on my MacBook Air and it always cuts up in the exact same places... Any ideas why??
