  1. Hi Neil,

     

    If you create MPEG-2 files with all I-frames (key-frames on every frame), that could work.

    There are no guarantees, but worth a try.

     

    I would compress outside of After Effects, though.

    Telestream Episode/Episode Pro is a good choice for this task.

  2. Hi all,

     

    We've discovered an issue with capture delay, when Datapath AND any Blackmagic card,

    Decklink or Intensity OR even only the drivers for them, is installed at the same time.

    As soon as the Blackmagic hardware/software is uninstalled, capture seems OK again.

    This is under investigation at the moment. Just wanted to give you a heads up on this.

     

  3. WATCHOUT 5 - Multi output

    All outputs MUST come from one card.

    WATCHOUT 5 Multi output ONLY works with one graphics card.

    That one graphics card may have up to six (6) outputs, provided the graphics card vendor
    includes driver support for multiple outputs under DirectX in 3D mode.

     

    This should be in extended desktop mode, do NOT involve any Eyefinity group setup.

    For FULL functionality in Multi output mode, Windows 7 SP1 is a REQUIREMENT.
    WindowsXP will not work reliably in Multi output mode.

    Performance of this is of course HIGHLY dependent upon hardware chosen and the selected content/encoding.
    It's VERY easy to run out of resources, with 6 1080p streams out of one Display computer, if not careful.

    All outputs also MUST be the same resolution AND refresh rate. 

     

    *) Since version 6.1 the displays can have different resolutions but NOT different frame rates.

       See the release notes: 

       Displays connected to the same display computer can now have different resolutions.

     

    This is not so much a limitation of WATCHOUT 5/6, this is inherent to the graphic card setup.
    Also related to keeping the sync between the different outputs.

    The AMD/ATI Radeon with EYEFINITY does support more than two outputs with WATCHOUT 5/6.
    Not all vendors do that. Preferably use the HD68xx/69xx-series for this, they are tried and tested.
    AMD FirePro 5900/7900/9800-cards are also very good, tested choices.

    With NVidia, maximum number of outputs from one card seems to be 2 or maybe 3, at the moment, depending on card chosen.
    How many of those one can get to work with WATCHOUT is not totally clear yet. 2 seems to be the limit.

    NVidia NVS series will not do, they lack sufficient DirectX/Direct3D hardware acceleration for WATCHOUT-use.

    Same thing with AMD FireMV and Matrox M91xx-series.


    Irrespectively the number of connectors, DisplayPort or MiniDisplayPort, all outputs over two (2) “legacy” connectors,
    VGA/DVI/HDMI, MUST use ACTIVE DP/MiniDP—>DVI/HDMI adapters, passive will NOT work.

    Or use displays/projectors with DP/MDP inputs. Not yet so common, unfortunately.

    There are 2 different types of ACTIVE DP/MDP-adapters, Single-Link DVI and Dual-Link DVI.
    Single-Link DVI - cheap, resolution up to 1920x1200, powered from the DP/MDP-connector
    Dual-Link DVI - more expensive, resolution up to 2560x1600, powered from separete USB or external Power Supply


    SOME EXAMPLES, not all tested by us:

    6 outputs:

    5 outputs:

    3 outputs:
    http://powercolor.co...ures.asp?id=342 (SINGLE SLOT)

    http://www.newegg.co...N82E16814102920
    Maybe a bit weak, but cheap…


    AMD:s professional cards, FirePro, are an alternative, although somewhat more expensive:

  4. Yes it will, actually.

    Automatic MDI/MDI-X is standard on almost all NIC:s and switches nowadays.

     

    Also referred to as: Automatic crossover, Auto uplink and trade, Universal Cable Recognition and Auto Sensing

     

    "If one of two connected devices has the automatic MDI/MDI-X configuration feature there is no need for crossover cables.

    Introduced in 1998, this made the distinction between uplink and normal ports and manual selector switches on older hubs and switches obsolete."

     

    It will never hurt to use a crossover-cable, although not necessary.

  5. Neil/David,

     

    It's not a manual page number reference.

    I was referring to basic computer & networks trouble-shooting.

    When having strange issues like these, go back and start over with as simple setup as possible, and test that first.

    Just to add my experience to the pot, it's essential to use the shortest possible dual-link cables as source

    and program links between Encore processors, (the cables supplied by Barco Folsom are, I believe sourced

    from Pacific Cable, and these are very good. I've always purchased replacements from this source when ours get lost/ damaged.)

     

    As has been mentioned by others, Encore is very fussy about these cables, sometimes needing to swap cables

    that are perfectly good, (tip - sometimes justreversing the direction of a cable will do the trick)

     

    Also, use highest quality available cables, (Lindy blue-stocking cables are good, not sure of their proper name),

    between watchout displays and Encore VP,s, as short as possible, and NEVER more than 2 metres.

     

    Good luck

    We have been using the Encore for many years and added Watchout 4 as both background and

    foreground layers a couple of years ago. The Program Link and Source Link cables are a constant issue.

     

    We build our rack to use cables no longer than 3’. Most are only 1’. Don’t forget to use only DVI-I Dual Link cables.

    Most of the problems I encounter is when someone has accidentally substituted a different DVI cable.

     

    Barco has included a “Test Links” item under Widescreen Links Diagnostics that has proven to be quite a

    time saver when tracking down that one bad cable.

     

    Also when doing blends of more than 4 or 5 displays I have found that it helps keep things in sync to have

    longer cables connecting the first two playback computers and shorter cables connecting the last two.

     

    Again keeping the DVI cables as short as possible.

    If I do not have room to put the Watchout computers on the Encore VP rack

    then they are setup next to or immediately behind with the computer connector panels and the

    Encore connector panels facing each other.

    If I may suggest...

    that all of us start posting items like this on the online forum vs. the email forum.

    In case some of you did not know, Dataton has now built an online forum at the following location:

    http://www.dataton.com/forum

    The benefit to posting there (instead of via emails) is that folks can now search the forum database for answers to things,

    and no one has to rely on their own email archive for recalling a topic.

    And folks like David won't have to "cut and paste" notes... rather he can log into the online forum and search "Encore".

    Not to mention that entire threads are laid out in a nice, traditional, sequential manner.

     

    Please join me in my quest to adjust the WATCHOUT user base's forum habits!

     

    Thanks,

    JJ Myers

    thanks for sharing.

    Its great to read some technical details /problems with Barco Encore as from a Watchout freelancer Encore & Spyder

    a rare bit of a mysterious black art and any small amounts of information are worth having.

    I will be cutting and pasting the notes from your thread to keep safe in case of emergency.

     

    many thanks,

    Thank you for your help.

     

    Found a source link DVI cable not performing well

    (No picture from input on the VPs other that the first one), but the problem was still there.

     

    I ended up using Watchout to do the blend without feathering and set the background in overlapped configuration.

    One last thing, encore is extremelly dependent on cabling, I do not count the amount of times a cable

    that was otherwise working well introduced delays and lag in the system, every single setup we do we

    have to do the cable dance for source link and program link, we use dual link cables, as short as possible,

    huge bandwith and even then we always have to change a few.

     

    Most of our guys that starts on encore do not believe us when we tell them their lags are the result of cabling

    but have to face the facts at some point, encore is ultra picky.

    Never rule out cabling, especially if after trying what I suggested in my previous answer it still does not work.

    Typical setup for me I think I know what's up, seen it before. Still not sure if the culprit is watchout

    not syncing well on a stitch or if it is the pixel doubling of encore that introduces a cumulative delay

    (center screen generates two doubling, sides generate just one) or some form of uneven latency

    but here are the solutions:

     

    - have Watchout overlap and specify in your widescreen menu in the encore controller that the background

    is overlaped rather than edge-butted.

     

    - In watchout put each screen in their respective tier (you will need to create those tiers, cut the display from

    the main tier and paste it in the new tier, it will keep it's location).

    This will have Watchout share content between projector without feathering and fading the blend.

    You keep encore feathering and alpha blending capabilities, just remember to put pixel doubling off

    in the widescreen menu of encore.

     

    - Or/and-create a pre-split video and import the proxy in your timeline, watchout keeps a better sync on a stitch

    when done as a pre-split, have no clue why but I have experienced this a few times so I know it helps.

     

    - Or/and-last but not least you can put Watchout as a foreground in encore rather than a background,

    this will let you use Watchout to mask you PiPs and in weird playback situations you can use an extra

    watchout head just to playback the problematic videos and use encore to scale them to the wanted size,

    as you know encore scales very very well and for most content a doubling in size is easily doable with very clean results.

     

    Hope this helps

    Your Encore system is not configured correctly.

    W/O has to enter Encore in the unscaled BG layers. All W/O sources MUST match it's corresponding VP's

    output pixel space and W/O overlaps MUST all match the Encore's overlap settings.

     

    Then in Encore - and I can't remember the exact settings - it must honor W/O's data doubling, but apply Encore feathering.

    W/O's feathering needs to be turned OFF. Essentially - at this point - Encore is maintaining W/O's per display data,

    but enabling feathering on the Encore side, so that other Encore layers (on top of W/O) can be feathered appropriately as well.

     

    If you still have trouble, I suggest you contact an Encore operator who has done this before for some consultation.

     

    Best of luck,

    JJ Myers

    Hi everybody!

     

    We have a 4 Watchout 4 system that we are using it to feed the background into a 3 screen Encore blend.

    We do 1920x1080 and I am trying to track down the following problem:

     

    If the blend is set-up to be done with the Encore there are small loose of sync times between the Watchout computers,

    which can be seen especially on the dynamic content videos. If the blend is done with the Watchout, everything is in sync,

    but you cannot use the Encore to do pip over the background.

     

    Any ideas why the Watchout is loosing sync when you have the displays side by side and add a wide video over all of them,

    but not when they are overlapped?

     

    Thank You!
