I am the Senior AV Broadcast Technology Analyst at Loyalist College where I primarily design, install and maintain campus AV and Broadcast systems and equipment. I also do some teaching for Camera, VFX and Audio/Video editing there as well and I love my job. My background includes Broadcast Television, Video Production and Technical work. My passions include digital art and drawing, VFX, VR, and sometimes 3D modeling. I have also recently taken up an interest in programming and development on the RaspberryPi and Arduino as I expand my interests into robotics.
I am one of those rare people that find themselves most comfortable in the chaotic limbo between the creative and the technical with the burden of proving one can indeed be both. Which is probably why I am loving VUO! :)
The Logitech C920 only provides 30fps at 1080p with applications that supports H.264 directly, and can pull in the H.264 stream directly from the camera. The C920 does on-board H.264 compression, but most applications don't support pulling the compressed stream straight from the camera; instead, they have to decompress then re-compress the stream, dropping the framerate.
Does that sound right? Does VUO support H.264 camera streams?
Partially occlude datamatrix (or sometimes just leave it as it is)
Output from datamatrix node sometimes jumps back and forth between numbers and proper reading of text.
We had a few instances of the Barcode node incorrectly reading a Datamatrix and ended up displaying numbers momentarily rather than the text that it should have read. Sometimes it was briefly, sometimes it flipped back and forth between numbers and a proper reading and other times numbers were visible for a few seconds before it was read correctly and displayed text. We also had a couple of instances where it displayed numbers when it decided a wood grain was a barcode (The card holder we have the camera mounted to was made of wood). This got me thinking that because the barcode reader can read different types of barcodes perhaps before it read the datamatrix as a datamatrix that it may have incorrectly identified it as a different type of barcode and spit out the results before correctly detecting it as a datamatrix. I think a simple fix might be to add a drop down list of the type of barcode we would like the node to look for. This could prevent incorrect identifications.
I managed to snap a few pictures of two incorrect readings of the same datamatrix (one with a partially occluded datamatrix) along with the correct reading. Because it contains student information I can't post it here but could privately send them to you.
