A studio sent me a “slide” as a .jpg with a request that I put on a USB stick, and load it on the projector and play it ahead of a screening. Never mind the distinction between server and projector, I know I cannot do that. The server wants DCPs and the disk players want disks. One could display it from a laptop I suppose but the best solution in this situation is to make a DCP with DCP-MATIC.

My setup is an NEC NC1200C with a Dolby DSS200 (media block within server).

What I would like to know, just out of curiosity, now that there are internal media blocks and internal servers, is there any setup where this is possible? Just walk up with a jpg or other media file on a USB stick and play it?

DVI Input via a laptop or computer.

Some Blu-Ray players will do it.

But never by plugging it into a server or media block, right?

Many Sony Bluray players have USB input and can read .jpg still images. I believe other brands also have this capability.

You're lucky- - at least you got a JPG. I've been handed "slides" people
wanted on screen that were MS-WORD or PDF documents.

Here's my suggestion:
Take the JPG slide & make a "still" DCP using DCP-0-Matic.
It's VERY simple to do, and I've had to do this so many times under
similar circumstances that I can now churn one out in 5 min or less.

You can specify a particular run length, and even fade in & out.

I had to do one of these last minute just a week or so ago.

I was given a JPG image of a logo the client wanted to appear as
a slide on screen as people entered the theater and during the show
intro, and come up on screen again after the feature during a Q&A.

> I made a 20sec DCP of the slide with the fade in & out and added it
to the playlist just before, and again after, their main feature.

> I also programmed a [PAUSE] into the playlist. so that the 20sec
slide would pause half way through & stay on screen as long as needed.

> After their live intro, when it came time to start the show, I hit [PLAY] on
the serverthingy and had 10sec to deal with taking out stage & house lights
and killing microphones, etc until the logo slide faded out & feature began.

> At the end of the festure, I again attached the DCP Logo clip, which played
10sec and paused then automatically paused agan & stayed on screen
for the length of the Q&A.

As I said earlier, I've had to do this so many times, and always it seems
at the last minute, that I have sort of a 'template' I've made in DCP-O-Matic
so that all I pretty much have to do is name the project and put in the
image file, and the rest (fades, length, etc) are already 'programmed'.

Works like a charm! [thumbsup]

Oh, I immediately went to DCP-O-MATIC and made a DCP which runs just fine. I was just curious whether this is ever possible.

A cinema playback solution is something different than a home media player, which will just work when you plug in the USB stick and select the JPEG.

If there would be support for still images in modern playback servers, they at least need one extra option and that's how long to show the JPEG on screen.

I think your DCP-o-Matic solution was the most reasonable and I'd taken the same approach.

I don't know any DCI server that plays a JPG (or any other common media file) without prior conversion. Yes, some 'projectors' can display still images as test images, but these need to be PNG, not JPEG, and you need installer/tech tools to use them that way.

Some servers are able to play h.264 oder VC1 video, but, usually, not as plain files, only when wrapped DCP style (similar to deprecated MPEG2-Interop), or using streaming methods.

It would be handy if BDs and DVDs (or specific files therein) could be played on a server and even incorporated into a timeline.

That would be interesting. Just plug a USB Blu Ray ($25) into the internal server and somehow play stuff off it. You could avoid all the HDMI issues...

I always kind of wanted a D-cinema server that would take a Blu-Ray or DVD and make a DCP out of it. It's easy enough to do this on a computer, but a fully automated process (insert disk, wait 12-24 hours, DCP is ready to play) would be so great.

I'm not sure why this isn't a basic function of the equipment.

Something like "ingest from DVD."

Such function would only be useful if it could deal with encrypted DVDs and Blurays, and that process is illegal in many countries.

Basically all countries that have implemented something like the DMCA. But it would sure be great to have something like a DVD/Blu-Ray/external playback solution that could be better tied into a playlist.

I guess once alternative content becomes more of a dominant thing in average cinema operations, those features will eventually materialize. In that case, your playback machine will become more of a central show-controller than just a DCP playback machine.
