Hello Kerthana,
There are two places to load "files":
The red box in the image below shows how to save a Pattern Design and how to load a Pattern Design once saved:
For an example of Pattern On-the-Fly file that you can load see this directory on your GUI installation:
C:\Texas Instruments-DLP\DLPC900REF-SW-4.0.1\DLPC900REF-GUI\LCR6500_Images (or wherever your GUI is installed)
Find the *.txt files there - a good example is add_400.txt, which loads 400 1-bit images.
The red box shows the Save and Load functions. The magenta box enables recording batch files to be Saved and later Loaded.
For this, record a few simple commands and then save the file. You can edit the file and then load it.
Unfortunately both files are *.txt files. If you attempt to load the wrong type it will give an error message.
A great deal of this is covered in the DLP LightCrafter 6500 and 9000 EVM User's Guide (Rev. D).

Keerthana,
At this time the system does not comprehend directly loading a video as input.
It is possible to build it up as 8-bit patterns from a video.
Can you let us know what you are wanting to do, to see if there is another path to get there.

Hello Keerthana,
You can certainly upload the file and we will look at it. I don't want to make any promises until I see the pattern(s).

Hello,
I couldn't post the video so I'm posting a youtube link to help you understand what I need.

This particular group used a WINTECH4500 projector which uses a DLP4500 chipset I guess. The GUI should be the same?
Please let me know if you can help me?
Thank you
Keerthana
Hi Keerthana,
The 6500 GUI and chipset has more advanced features than the 4500.
The shapes that are printed in the video could be achieved by the fast switching speed of the mirrors (the architecture is not shown in the video though).The formats and pattern sequencing are those that Ben defined earlier in the thread.
Ben will be able to reply later this week.

Matt
Hello Keerthana,
We saw a paper at Photonics West on this technique. Very impressive.
I believe you can use Video Pattern Mode and build a video that you want to show with the patterns you want to project in the video.
If you use RGB as input and only need 8-bit grayscale then you can simply build a video that treats R, G, & B as three 8-bit grayscale patterns.
Then connect the computer as a "monitor" and run the video.

Hello.
Can you tell me the steps on how to use the video mode?
Also, I was able to save the video as a string of images. I'd like to know If I can scale up the images or change intensity on the projector?
Thank you
Keerthana
