Detecting NTSC or PAL on a PCI-1411

I need to determine whether a signal is NTSC or PAL. Can the PCI-1411 do this through Labview?

I've discovered a solution for myself and thought I share it for those interested.
Its a simple case of counting how many aquisitions are made in a defined period. I've used the IMAQ Grab function synchronized on vertical blanks to provide the count increment.
ie
25 or less counts for PAL
above 25 counts must be NTSC.
As PC background tasks and hardware speed capability can sometimes cause IMAQ Grabs to be missed and my VI being asynchronous, counts are not always exactly 25 for PAL or 30 (29.97) for NTSC. The above figures seemed to be a good compromise. I've attached a small VI that performs the function.

Photo camera with pci 1411

Hi,
I checked several posts for image aquisition but I did'nt understand wether I can use a digital photocamera with my PCI-1411. We have to take pictures regularly timed and we have available a compact photocamera and a reflex one (Canon 500D). Would a converter S-video to USB be anough to connect the camera to the PCI-1411?
Any suggestion is more than welcome!
Giacomo

Hello Giacomo,
Sorry for my late reply.
The flu and some other issues came in the way.
To be able to acquire images wit he PCI-1411 the only restriction is the type signal you're providing to its inputs.
In the User Manual (http://www.ni.com/pdf/manuals/372157d.pdf) You can find the 2 different supported types at page 3-2:
- (Composite) Video
- S-Video
More info can also be found in this document (http://www.ni.com/pdf/manuals/374550a.pdf)
The NI 1411 device supports both
NTSC and PAL color standards as well as the RS-170 and CCIR
monochrome standards.
So what you'll have to check is:
- Is there an S-video or Composite Video output on my camera? (I don't think this is the case with your cameras)
- Can I somehow convert my signal to S-Video/Composite Video?
There exist things that you can buy online for this.
Normally you can use any camera that has these types of outputs and that follow these standards:
- PAL/CCIR (25 frames/sec)
- RS-170/NTSC (29,97 frames/sec)

DVI to Video adapter switches from NTSC to PAL

I just bought an apple dvi to analog video adapter to connect my mac mini to my tv.
It worked like a charm the first time, but seems to reset for no reason from ntsc to pal output. This is really annoying because the pal output is nearly impossible to read, making it painful to switch it back. It's weird because it boots into ntsc just fine and the login window looks good. But as soon as I log in from either account, it opens in pal. When I change it, it will change back over night.
I tried using both composite and s-video plugs. The TV is a sony wega xbr (US).

I assume you have the previous generation mini even though you have posted in the forum for the newer one. The newer one wouldn't work at all from the adapter you describe. Anyway...
...OS X's display preferences files may have corrupted somehow. Especially since it worked before and now it doesn't. That really sounds like a problem with the configuration of the Mac.
In /Library/Preferences is a file called com.apple.windowserver.plist. Navigate your way to it and throw it in the trash. Also, in your main user account (folder with your name on it) under ~/Library/Preferences/ByHost will also be found a file com.apple.windowserver.xxxxxxxxxx.plist where the xxxxx is a hexidecimal string. Throw that file in the trash, too. Now restart.
When OS X restarts and finds those files missing from their expected location, it creates fresh copies with default values. This will give a clean start with any attached display.

DVD Footage for FCP Edit - how to tell if NTSC or PAL?!

Hi all, apologies if this seems like a stupid request but I have a job at the moment calling for me to extract footage from a DVD, edit in FCP, add a few bits from Motion etc., but I can't work out if the DVD is NTSC or PAL!
I intend to extract the video (no issues with copyright) via DVDxDVPro but am unsure if the DVD has been encoded in NTSC or PAL. The footage it contains is from both the States (NTSC) and South Africa (PAL) so how do I tell? I don't want to go through a standards conversion if I can help it.
I am keen to try to retain as much quality as possible (client can't provide tape) so also any thougts on the best output from DVDxDVPRo for FCP editing?
Thanks all,
Best wishes
Michael

Hi Thomas, that's it!
Thanks for this - it clearly shows the TV standard and the resolution plus 4:3 etc., so everything I needed for confirmation.
Glad I cheked because it was in Pal - thought the conversion in DVDxDVPro looked a bit ropey.
This realy baffled me - seemed so simple but couldn't find a way to tell the standard. Learn something everyday...
I am using DVCPro for export from DVDxDVPro - anyone thoughts on a better option?
Thanks again for the answer - and so quick on a Sunday too!
Kind regards
Michael

Follow up from Real Pro thread - NTSC and PAL and AVCHD and FCE

Interesting topic line but can I just check one thing out from PAL land.
With an HD/AVCHD camera it is not recording in either PAL or NTSC as this is a analogue mode - so the issue issue of format is only relevant if i playback on a analogue TV. We have a digital tv so i record on AVCHD, deal in that format in FCE and burn to DVD (not sure in what format) play on DVD player through the digital TV.
If that is all correct then why do the manufacturers, in my case Canon HF10, talk about an NTSC and PAL version and then price differently - comparing the spec sheets from the Canon site I can see no difference. Am I missing something?

Hi Tom
The thing i was trying to establish was whether really there was a difference (other than price ) in the so called versions of the Canon HF10. The specs are exactly the same. My assumption is that as the cam records in AVCHD unless you intend to play back thro a PAL or NTSC TV (bearing in mind most European PAL sets play NTSC as well) it makes no odds which camera.
My plan- and this is what I need to check - is to record and import into FCE taking your advice not to record in the highest quality to save rendering on import. After editing can export through FCE to PAL or NTSC DVD version for playing on TV.
Does that sound right
PS I have found your book on FCE very helpful to date !!!!

Where can I check to see if project has been imported in NTSC or PAL?

I have been importing DV tapes from both NTSC and PAL DV camcorders and I think I may have made a mistake on a take and recorded an NTSC tape in PAL. I can't find anywhere that tells me if my projects are in PAL or NTSC. Does anyone know how I can check?
Thanks

Ntsc vs pal

pal vs ntsc
Posted: Oct 18, 2006 8:27 AM Reply Email
i got some footage of a wedding that was shot in ntsc format on vhs that was burnt do a dvd. i recorded the dvd onto my computer using final cutpro (dvd to cmaera to computer). I saved it as a quick time movie, now i want to burn into a pal format film so it can be shown in England. How can i do this with idvd.
I tried changing the prefernces to pal and i tried changing the video mode in the project info to pal but i get an message when i click burn that says TV standard conflict. i still go ahead to burn but it comes beack with an encoding error.
is there anyway i can change the format (ntsc to pal) using finalcut express

to playback your ntsc dvd (vhs for that matter) you need either
- a dvd player or vhs deck that does true ntsc playback plus a monitor or projector that handles true ntsc
or
- a dvd player or vhs deck that does "ntsc playback on pal" (i believe that's what it was called) with a regular tv. it's a rough scaling of the video-image and it drops a few frames here and there to compensate for the frame-rate difference. this is of course not as good as a proper conversion, but for home-viewing is more than good enough.
this last pont also explains what is the point of places offering proper conversion...
discs created in dvd sp usually are set to play in all regions - though can be made to play only in 1 region, you'll have to check this with the person who created the disc or by popping it into a different region player
hope this helps

NTSC and PAL

Under iDVD preferences and the Projects tab it asks a few things that I know nothing about:
1) Video Mode: NTSC or PAL. What are those and when would I use one over the other?
2) Encoding: Best Quality or Best Performance? Which is better to use and if I use Best Performance do I want to "Enable background encoding"?
Thanks. -Jeff

there are no NTSC DVDs, there are only DVDs that have 29.97fps, 720x480 MPEG-2 video to maximize video quality on an NTSC analog output
... and THAT makes them NTSC DVDs.
Jeff asked: ) Video Mode: NTSC or PAL. What are those and when would I use one over the other?. Jeff, the are video standards used in different places around the world. If all your DVDs are intended for use in the US, just select NTSC and don't worry about it.
PAL and NTSC are analog modulations
... that differ mostly in the way the chrominance signal is treated (besides the image size and frame rate).

NTSC to PAL DVD

I am attempting to make a PAL DVD in DVDSP 3. I changed the disc and encoding settings to PAL and encoded my stand alone movie from media 100 which was 720x480 as PAL.
I watch the DVD on my g4 apple dvd player and it's fine, but when I watched it on my apex dvd player, I saw these lines running across horizontally. Thick lines, mostly on fast motion, but other places too.
When my client watches the same dvd on his computer, (mac 0s 9 i believe) he sees what I see on the apex.
Question: Is this normal, since my monitor is NTSC to see these lines? Normally when I've watched a PAL piece on a PAL player on an NTSC monitor, I see color problems and tracking problems... but not these lines...
Also: What is good for a stand alone program, to convert files from NTSC to PAL?
Thanks in advance to anyone who can help me.

You can't just encode from one standard to another
You need to use a standards converter, or have original PAL footage
What do you mean by "I changed the disc and encoding settings to PAL and encoded my stand alone movie from media 100?"
Just changing to PAL in DVD SP if the original footage is NTSC doesn't change the source footage and creates a PAL DVD.

NTSC to PAL Compression for DVD Studio Pro

I am trying to make PAL MPEG2s using Compressor. My videos are roughly 15 minutes long (I have 6 going onto one DVD). I altered one of the Presets to PAL, 16x9, one pass VBR, 4.5 to 7 data rate, best for the motion setting. And I get the typical odd chunky feeling during motion within the frame. Meaning frames look removed (or added) during movement. I looked at it not only on my MAC but on a PAL DVD routed to a true PAL monitor.
Any advice for settings I should try? I have two tests rendering - I moved up to 2 pass VBR, 5-8 data rates, better motion and best motion. I should be able to look at them this evening; but from the folks I talked to, I'm not hopeful. Has anyone figured a way to make PAL MPEG2s look good short of having PAL masters made and a large Post house do the files on their very expensive equipment?
Thanks,
Cindy S.

What version of Compressor are you using? Compressor 2 has frame rate conversion settings under the Frame Controls tab (offering various levels of quality).
In any case, you might want to try the freeware utility JES Deinterlacer since it supports fairly good NTSC to PAL conversion using either frame blending or a form of inverse telecine (to convert from NTSC's 29.97fps to PAL's 25fps). If you're using Compressor 1.X then this may be your best option unless you are willing to spend some money on an alternative, third-party solution.
You can download JES Deinterlacer from VersionTracker.com -- it comes with instructions.<small><hr width="75%"><small>If this suggestion helps in any way, a confirmation or acknowledgment would be appreciated, since that would also help others who may be having the same difficulty.

HD NTSC to PAL Debacle

Dear Compression sages,
I'm attempting to convert my NTSC DVCpro HD 720 Quicktime to PAL to make a PAL DVD in DVDSP. So I need a PAL mpeg2. My trouble starts here.
In compression I followed all the settings to convert to PAL. The resulting mpeg was a little rough in terms of quality, but it was the best I could get it. It seemed to play alright.
But to my horror when I dropped the clip into the DVDSP timeline I discovered that all the subtitles I had made in my NTSC DVDSP project gradually went out of sync. The DVDSP project had been fully converted to PAL, every menu. But this gradual de-syncing of the subtitles confused me. And this is not the kind of project that I can easily move the subtitles over. 26 min, heavy on the lines, 5 subtitle tracks.
I checked the audio sync and it seemed to be in sync, but I couldn't be clinically certain frames weren't being dropped towards the end. I did some research and discovered that many people had been having trouble with conversions from NTSC to PAL. Out of sync audio issues, frames being dropped, etc.
In desperation I consulted a friend, who recommended I use a FCP plug-in to do the conversion called Nattress Standards Conversion. He said he had had frame dropping issues with other transfers, but that the NSD plug-in had worked great.
I downloaded the plug-in, and attempted to follow the instructions (bellow) only to find that on step 9, it did not recognize the proper aspect ratio of my HD footage, giving me 4:3 instead of 6:9. I tried switching a few settings, but to no avail. Everytime I dragged and dropped the origional source clip into the filter interface the clip in the viewer altered to 4:3 ratio. Blast, I thought. Probably some little setting I will never discover.
So here I am, back on the compression forums. Has anyone successfully used compressor to convert NTSC HD to PAL without getting drop frames or subtitles gradually going out of sync? How on earth do I do this conversion without horrific results?
NTSC to PAL conversion for Nattress:
1. edit the NTSC clip to an PAL timeline
2. nest the NTSC clip to allow the plugin to scale the converted clip. Because the pixel
dimensions of NTSC video are smaller than PAL, the clip will appear shrunk down in
the timeline canvas viewer. This is normal. The nesting of the clip will allow the
plugin to correctly scale it to PAL pixel dimensions. (select clip and go to the Se-
quence Menu and select Nest Items - make sure the pixels dimensions of the nest
are PAL sized)
3. apply the G Converter plugin to the nested sequence in the PAL timeline. Make sure
the plugin goes onto the nest itself, not the clip that it contains.
4. open the nest in the viewer (control click on the nest and select "Open in viewer" or
select nest then press return)
5. select the ﬁlter tab in the viewer
6. set the correct settings for the desired conversion. In this case, we select Source
Pixel size to be 720 x 480 (NTSC), lower ﬁeld order for source (in this case a NTSC
DV clip) and destination (PAL DV timeline).
7. if you desire the PAL output to be de-interlaced, this can be performed in one step by
selecting progressive output
8. if you would like to experiment with the conversion algorithm using "Smart De-
Interlacing" then this can be selected in the De-Interlace options. The Tolerance
control affects the smart de-interlace and it's effects can be seen by selecting "View
Smart Mask" in the De-Interlace Options.
9. the original NTSC clip that was edited to the PAL timeline must now be dropped from
the project browser onto the Source Clip image well in the ﬁlter. The plugin will use
this video clip for all the image data for the conversion. This is the important step
that makes this plugin different from any other, and is vital to it's successful operation.

I downloaded the plug-in, and attempted to follow the instructions (bellow) only to find that on step 9, it did not recognize the proper aspect ratio of my HD footage, giving me 4:3 instead of 6:9. I tried switching a few settings, but to no avail. Everytime I dragged and dropped the origional source clip into the filter interface the clip in the viewer altered to 4:3 ratio. Blast, I thought. Probably some little setting I will never discover.

Blur video frame with NI PCI-1411 and JAI CV M-300 camera (urgent problem)

Hello,
I am new with Vision and I need some advice with a problem, which I encountered.
I have a computer with integrated NI PCI-1411 board, which is connected to a JAI CV M-300 camera. I am measuring a steel part which is positioned in a dark chamber. The part is put on a glass board and is illuminated from underneath with light.
The part is moving. I have to measure this part when it reaches the camera region. I have made a test with not-moving part and everything is perfect. Now, when I move the part I get blur frames from video (with these no part measurement is possible). I need specify, that the camera has no trigger, so it makes video all the time (this video is later inspecting with Vision Builder).
I have tried to change parameters in MAX, but no involvement. I have found no proper icd/file for the camera.
I also could use a SONY DXC-950P camera, if this is better.
How can I eliminate the blur from video frames? Or what am I doing wrong? Is the camera not good enough? Camera + trigger would get better images.
I have attached the video frame with moving object (static) and the blur video frame with moving object (dynamic).
Please give me a answer or ideas as soon as possible.
Thanks.

You are using an interlaced camera. It takes half the picture (every other line), waits a split second, then takes the other half of the picture (the other lines). When it puts the two images together, you can see the two positions it was in when the images were taken.
The best solution is to use a non-interlaced or progressive scan camera, which takes the entire image at one time. The Sony might be this type of camera, since it has a P in its name. I didn't look up the specs.
If you can't get the right kind of camera, your only other option is to use fields instead of frames. One field is the half image taken at one time. The image will be half the height of the original image, though, which can mess things up.
Another possibility is the reduce the resolution of the image. If you take every other pixel in both directions, you will have a very clear image that is half the size of the original. You can do this with Extract in LabVIEW, not sure if it is available in VBAI.

Mistakenly changed from NTSC to PAL - Help!

My display settings on my mac mini were changed from NTSC to PAL (all i will say is that it involved a 3 year old) and now i can't get an output to my display. how do i change this??

Try starting in Safe mode. If that works, change the resolution from whatever is the starting resolution to another choice. For example, if it comes up at 640 x 480 NTSC, change to 800 x 600 NTSC. Then restart normally. Hopefully that will get things back to the way they were before.

Exporting 14:9 video for NTSC and PAL

Hello,
I'm working on 1080p video that will need to have a few output format, namely HD and SD 14:9 for NTSC and PAL.
At the moment I have no issue with getting the 14:9 video inside SD format, but my question is more of, should I turn my aspect ratio to PAL, NTSC, or should I keep it as square pixel? Viewing from inside a computer, the ones that has aspect ratio looked a bit squashed or stretched, and that worries my producer. I'm not technically savvy enough in broadcast knowledge to ensure her that everything is going to be fine once the video goes into broadcast, hence I'm posting the question here. I did my search on the web, but nothing seemed to help. Or maybe I'm just a big doofus that missed the very big hint in front of me. If anyone could help me figure this out, or point me in the right direction, I would really really appreciate it.
Regards,
Deo

Hey guys. Thank you for your input.
I think I may have overcomplicated the question in my state of panic with the 14:9 thing. Yes, the client did ask for 14:9 video, which to my knowledge is a scaled down HD video in SD sequence. A bit bigger than 16:9 in SD sequence, with smaller letterbox and cropped sides. From what I've read (in wikipedia), it's used in UK, Irish, French, Spain, and Australia. So the PAR should still follow SD PAL and NTSC PAR.
I've been barking the wrong tree, and after reading this, it seemed clear that I should be using PAR as TVs pixel is not square. And it's fine to have squashed and stretched picture of these outputs because computer's pixel is square. Right?
I'm not really in a position to ask the station, as this is a regional job with a few countries involved, so I'm not directly in contact with the stations themselves. But hypothetically, if I can ask, will they give me a set of guidelines to follow?
Regards,
Deo

FCE 4: NTSC AND PAL?

Hi, this summer I bought FCE, but I really still have to learn using it. Now I saw that between the description of the FCE 4 upgrade, it says that you can use Pal and NTSC footage in the same timeline. This means that if I upgrade I can use in the same movie some shots from my NTSC camera and some of my Pal camera and then export the all movie in whatever format I may like? (NTSC or PAL)
I'm asking because, if this is true and the results are good, This can be a good thing to kick out of my pocket another 100 €...
Thanks in advance for any help.

Sandbox Test
1) being is a PAL orientated country, I download some NTSC footage from iStock Photos (iStock_000003835610DV.mov - NTSC, no sound, 720 x 480 px).
2) opened FCE4, and created a new sequence as "PAL DV 48kHz"
3) imported the NTSC footage
4) dropped the NTSC footage into the timeline, and it prompted me to either match the clip or not. for this purpose i said no, and the NTSC footage was converted to match the sequence settings.
5) the canvas view was at 72% whilst when i looked at the NTSC footage in the viewer it was 50% - PAL 720x576 whilst NTSC 720x480.
6) playback in the timeline without rendering, and all looks good.
7) exported as movie (not self-contained).
8) playback in QT7.4 side-by-side the original footage and naturally the width's match, but the FCE4 converted material was stretched to fill the difference.
9) changed the aspect/size to match that of the original footage and all looked normal.
I guess the morale here is mixing footage of different sizes will need some manipulation to make the final output look normal.
I am sure others more experienced with mixed media will correct my knowledge inaccuracies...
I hope this helps
