video projection
« on: December 24, 2014, 07:11:27 AM »
Next year I plan on doing a little different kind of show. I want to incorporate video projection into the show but am not sure how I control the projector with the Renard controllers. I am planning on using the Raspberry PI to control the show. I have one but it is pretty well still in the package. Did not get to it this year. We will just say this year was a disaster and the show did get off the ground. Had some late set backs that spelled failure.

If there are some posts on this subject please post them so I can start learning how this is done.
Thanks and Merry Christmas to all.
Terry

The Falcon Player supports native video playback and Renard output.

Setup your Renard Channel Outputs, create a sequence synced to video and convert it to the FPP's native .fseq file format.  Upload the sequence and video file to FPP. Create a playlist with the sequence file and video and play it or schedule it.  Pretty simple.  FPP will also playback synchronized video on multiple Pi's at the same time so you can do larger displays.

WOW that was fast. Thank you Captain Murdoch for replying. You are the master of this type of set up and I appreciate a response from you . I will dive into the forum once this season is over and I get the small display I put up at my in laws done for the year. At least I had one that worked.

The past week or so my free time seems to have been limited to 5 minutes here and there and your post happened to come up when I hit on another 5 minutes of free time. :)

We're glad to help with any questions you have, we had lots of users using video this year and quite a few Renard users I believe.

These links refer mostly to projection mapping.

I didn't see much referring to equipment setup, as much of it is projector specific, or to how to sequence but (very) generally these are the steps I followed:
1) create projection mapped video to be projected
2) if necessary, use Audacity (or product of your choice) to create mp3 audio from video
3) import the mp3 into your sequencing software
4) sequence to the audio as you normally would, taking care to reduce the brightness of any effects close to the projection
5) after you have a sequence that matches your audio/video convert it to an .fseq file
6) download your sequence and video files to your Pi FPP (the audio will come from the video)

If your hardware is set-up correctly,

Channel Outputs
 PixelNet mapped to pixels/DMX (either E1.31 or Falcon/DMX)
 Renard controllers mapped to Other Outputs (Renard Comm Port(s))
Projector plugged into a video port on the Pi with audio forced in FPP Global Settings with the Force Analog Audio Output switch checked and transmitter plugged into the Pi's audio out

you just might be able to project an image on your house that is synchronized to the your lights.

Sorry this is so late, I wrote it this morning and then intended to attach a Vimeo link to one of my projection songs (I have 2 in my show) but no matter what I did, both of the Videos were rejected due to copyright, I guess you will have to take my word that it works.

Seems like a number of people are having trouble getting video on vimeo this year. Any one have a way to do this without problems?

Tried You Tube again and this time I accepted the copyright notice so they are up (for now). Unfortunately their quality is not great and you can only see the projection on the house close-up sections which I have listed, but at least it will give you an idea of how it looks (but it's much better in person :) ).
