Alec,
I understand that you are storing your content on an SSD, but is it an external drive, or
internal? If it is running off an external, you are limited to the data transfer rate of
your connection, whether that be USB, Thunderbolt, Firewire, or eSATA, and that might not
be enough for you to guarantee a sufficient stream. If it is an internal hard drive
(assuming SATA), you'd have a maximum throughput of either 1.5 Gbps or 3.0 Gbps (no
one ever reaches the upper limits, generally), so at that point, I'd start to look at
other hardware. To be sure, you should never test content from an external drive, just
because of the data transfer rate.
Also, what video card and CPU are you using to view it? On my tablet, such things stutter
a bit, on my work computer, it sometimes has a hiccup, and on my home computer, I'd be
surprised if I couldn't run two simultaneously with no stutter.
I tend to use Stereoscopic Player ( http://3dtv.at/Downloads/Index_en.aspx ) for my
playback needs (I bought mine, but the free version drops out after 5 minutes of playing,
but it's basically enough to ensure that the content looks fine, but the downside is
that it does not work with encrypted content). Oh, Carsten already gave you that link.
Well, I actually use that one, so I can at least endorse it. :)
Hope any of that helps.
Leslie

hello,
I recently created a DCP of my short film, but when I play it, the video stutters by a
LOT. I'm running a high end PC (Windows 7), playing the file off a SSD. I'm trying
to figure out asap if its an issue of my PC, the player I'm using or the DCP file
itself. The player is called DigitAll DCP Player, and I'm awaiting a response from
them on the issue. If its only an issue of the player, I should be fine since I'm sure
the venue at the festival will have good enough hardware. If it's an issue with the
DCP file though, I really need this figured out in time for next week.
Hi,
I have good experience with the DigitAll Player on a simple Dell i3 notebook with
integrated graphics. There are, however, different playback quality settings you can
choose. To check smooth DCP playback, try one of the lower quality settings.
Have there been any frame range changes between your source material and the final DCP?
What is the resolution and datarate that you chose when you created the DCP?
For a quick check, try http://www.3dtv.at/Downloads/Index_de.aspx on the MXF video file of
the DCP.
