@woland Well for example changing the shape of the fade, why would anyone ever want a value other than 1?  That sort of thing, a better explanation of the settings would be helpful.  And also it would be great to link the left and right settings together because almost all of the time I'm using the same values for right and left fades....

@ijevansdesign What kind of converter are you using to:

1. convert from a port on your mac to the connection on the beamer?

2. Extend the signal from your mac to the beamer?

3. Possibly decode a signal from an extension system to the beamer?

The issue you report (unavailble resolutions) sounds like part of your chain is not able to handle the bandwidth you are transmitting over a the cable/convertor setup you are using. Can you test the directly plugged in port and cable/convertor chain piece by piece with different convertors and cabling (the ones you know work)?

@merni As an extra tip, when you make the test pattern make it so it is cropped to the same aspect ratio of your blended screen. This makes it easier to know if you are warping the image. So if your screen (made of 4 blended beamers) is 4m * 6m make sure your test pattern is cropped to a ratio of 4:6 (eg 2000 pixels by 3000 pixels). Then you can line up the outer corners and edges of all the beamers and pull the inner corners in to match and blend.

If there are any features on your projection surface - door edges, holes, ridges etc it can be useful to mark them on the line up pattern too, as long as you measure them exactly and put them in the right place on the line up - it can make your line up faster and more accurate as you can quickly put the corners in the right place and drag the features to match.

Having perfect squares in your test pattern is very useful, you can measure projected squares with a tape measure and see if they are actually square.

Hi All just a very simple question. I loop movies a lot and sometimes there is a sudden jump between the end and start. Is there a way to introduce a crossfade so the end and start flow into each other less obtrusively?

This is a known limitation of the Movie Player on both MacOS and Windows. Mainly, the looping provided by the operating system (AVFoundation on macOS and Windows Media Foundation on Windows) always has this little pause at the loop point.

We are working on a solution for this for a future release (Windows is almost done; still have to deal with macOS). The main thing is to get away from MP4/H264 if that's the codec for your movie, because that's probably going to be the worst in terms of the glitch.

There are two possible solutions.

1) If you're on macOS, I would suggest JPEG (using the old QuickTime Player 7 if you can still run it) because that's probably the fastest. Otherwise, Apple Pro Res or HAP. On Windows, the best solution would be HAP.

2) Loop the movies yourself in an editing program and use those instead. If you want absolutely seamless loops, that's the only solution for now.

Sorry for the inconvenience.

Best Wishes,
Mark
