How about just changing the letters to black without using the invert=2 or the white = 1 anywhere on the screen?
Haven’t gotten as far as to know what you were talking about in previous messages but it sounds interesting. Another passage to take someday.

Went back and looked carefully. One looked a little short of solder. It was either 7 or 8.
That was it. All looks good now.

thanks

Happy to report that the cameras that that have a problem are Q-See cameras. Q-See is a brand name. At least in the group of CCTV cameras that were available for me to test the cams from Q-See are the ones that won’t sync perfectly.
The rest worked in both NTSC and PAL with the only difference being the exact placement of the overlay.
These Nootropic VE boards are awesome! They are easy to use in the world of Arduino.
So one last question, is there anything that will print rows of text to screen as easy as the Nootropic VE board?
I don’t think so. It is also a great programming and debugging tool. Printing to screen is a snap.
Thanks

Ok, have hooked up a new board with the same results.
This is using the same sketch that the pictures uploaded in previous message show.
Tried with the tv.begin(PAL, W, H).
It is better but not right. The bottom box of snow is all gone. The accuracy first is shifted all the way to the right where the arm of the t in first is just off screen right. The “accuracy” is flickering on it’s same row.
The numbers are on the right edge with a bit of the second number cut off by screen right.
The numbers also flicker but show five digit number as a flicker.
I mentioned before that the CCTV cams are PAL compatible but the reference to my knowledge at this point is unknown. Can’t remember the details of the reference. I can say that with the sketch that I am referring to in the NTSC version, there is a TV that will play it perfectly. So there are two situations I can reproduce.
1.Cam in the video that plays like uploaded pictures. Same cam setup will play on particular TV.
= same cam needs particular output device to work correctly
2.Then the actual situation uploaded in the pictures. Same output different results based on input
= different cams needed to make output devices work correctly

The second option worked on every output device in the store. Tube BW monitor, computer monitor driven by video to VGA box, 7 inch 12v headrest LCD monitor. I would say that signal would play on anything.

I have at least five different resolution CCTV cams. Going to see if any others work in NTSC or PAL mode. The cam that was used for the uploaded picture is one I didn’t install. It is outside on a pole so I have no idea about the resolution or make.
Any guesses as to what resolution will work? Anyone with any ideas?
Thanks

Maybe I should explain the pictures a little better. the larger sized one comes from a handheld shot with iphone. So there is slight movement you can see from the CH04 which is generated by the DVR. The DVR is also generating the very very bottom line that says;

2011-07-09 12:38:33 M2

Everything else is from the VE including the box of snow at the bottom.

This is basically what was happening to the overlay demo when I left a message last week.
The snowy box and a doubling of what is being printed to the screen.

The second smaller picture is a screen grab from slingbox today since I didn’t take a picture of a monitor like the handheld shot. The 20 in the right corner and the accuracy first is what the VE is generating. The CH01 is from the DVR.

thanks

Here are the pictures. VE board gone till another comes. Will test PAL settings.
Thanks

Hi Michael,

First off, enjoy your vacation! Looking forward to you getting back so you can ship the Digit Shield ordered yesterday.
So, I was going to get a screen grab of what the demo looked like to put in the email. Easiest way for me to get video on the Mac is through the Slingbox. Opened that up just a moment ago and the video was being overlaid perfectly!
Now my messages prove that just about anyone can get your board to overlay video. If a guy who can’t even install a library can do it!

Went back the other night and read many messages about installing libraries and did realize that the folder name was not important. Haven’t set it up to work yet but that’s next.

Thanks for your patience and replies

There are two overlay demos. There is one that is part of the library TVout-VE called DemoNTSC and there is the overlay demo on the Video Experimenter page of the Nootropic website. So the one from the library (DemoNTSC) has text that is scrolling down the screen but moving left or right very quickly. It is hard to describe since I have never seen what it is supposed to look like. It might be easier to tell you that the 3D image produces a line of objects that move left to right so fast as to produce one and slowly from top to bottom. If this is one 3D object it is being printed maybe 10 times from side to side to make a strip that moves from top to bottom in about ten seconds. the words at the beginning also fill the screen from side to side and scroll from top to bottom at the same pace as the 3d image(s).
the other demo is the one that is shown all over the web with the milliseconds? showing time, The graph, and “overlay text and video . . .”
This one reacts a bit differently. Everything that is supposed to overlay has been pushed up almost a quarter of the screen. Everything nearly stays put but doubles up left to right so there are two graphs for example. The time is pushed up so far you can only see the very bottom of the numbers. The scrolling words in this demo can be seen and read.
Hard to describe but the two react quite differently in that the DemoNTSC makes the words totally unreadable with this fast movement from one side to the other. It is like horizontal roll that creates duplication across the entire screen. The other demo looks like the overlay is too big for the screen so it is doubling up horizontally. Jeez, Sorry to be taking your time on this.
As far as the library thing goes, The way you described is the way the instructions go. I have tried this many times, just tried again today. I cannot get a folder named sketch to save my life and have tried many different ways. Today I was shown a folder when I asked to see the sketch folder. It was the folder with the name of one of my projects. So a sketch folder was made in the same folder as the found folder. Not recognized as the sketch folder. Quit and restart app. No joy. Go to preferences and put Sketch folder in sketchbook location. No change. Quit and restart app. No change. Rename the folder that it says it is the Sketch folder to Sketch. That blew its mind and now when asked where the sketch folder is I get this Path;
Macintosh HD/private/var/folders/o6/o6sts3inFlubAHsC4wyH/-Tmp-/untitled162759080553/sketch_jun30a.
and No, I don’t let web pages tell me “You have a virus and should install this software now!” :). It’s getting funny now. I’ve used Macs since they only used floppy discs because I thought they were easier! It is embarrassing to say how much time was spent with this Sketch thing to try and install a library. I thought I had found a way that worked. Like I said the Ultrasound Library installed just fine and the example sketches are even in the Examples of the File menu
None of this is anyone’s problem but my own. Just wanted you to know I am really trying before asking. I will try installing on a different mac while following the instructions step by step.
Thanks for your time

Thanks for the reply Michael. The problem on the Mac side is my own. Getting the Library installed correctly on the Mac has been my problem. The good news is I did get an overlay on live video from a CCTV color camera using a PC to upload to the arduino.
Putting overlay info on security DVRs is my goal.
My new problem is the demos have horiz and vert sync problems on the three different displays I tried. Thats assuming the sync problem is from the display. Two different inputs have been used one from the CCTV camera and one from the output of the security DVR. Any suggestions or sites that you might point me at would be appreciated.
Thanks again

So this seems to be a library problem. The TVout.h file cannot be found. It is where it should be in comparison to the other libraries but still says No such file or directory.

I’ll go and try it on the PC side

[variador]

Found an answer in Arduino forum from PrairiePoet and it works great;
“For Mac users, go to your Applications folder, right click on the Arduino.app and select “Show Package Contents”. Then navigate through that to find the Library folder.”
You will know you have the library folder for sure because it has EEPROM and all the others.

Rename TVout-VE to TVout put it in the Library folder you find and when you restart TVout will be in the Import Library dropdown menu under sketchbook.
