    Marvel G-200 ... Delay delay and delay

    Hi,

    I am wondering if anyone is having my same problem... Opening AVIs (Matrox MJPEG) ALWAYS freeze my PC for few seconds (e.g. the mouse is not responding while opening the avi), but when it's open it works fine.
    It seems the codec need quite long to initialize the Marvel for MJPEG playback.
    Same problem with Media Studio 5.2 and Premiere 5.1 (already BOTH configured with right parameters, INI files etc etc...).
    Both in MSP and Premiere EVERY TIME i click on the timeline to set the cursor on a ceratin frame, I HAVE TO KEEP THE MOUSE BUTTON PRESSED FOR 5-10... sometimes 13 seconds before the frame appears in the preview window... This happen ALWAYS ... 358x288 (PAL) @ 25 fps, 704x576 PAL @25 fps... Ths does not happen in Avid Cinema, and i think it's coz Avid keep someway the MJPEG codec "always open" so when i click on the timeline the frame appears IMMEDIATLY as it should do...
    I wrote to Matrox support about this "problem" coz it's making the use of Premiere and MSP very FRUSTRATING...
    (just think you have to cut the movie in 2 position.... click on position 1 ... WAIT 10 SEC with mouse pressed, click on pos. 2, wait other 10 seconds.... :-(((.... Click for a short preview..... WAIT OTHER 10-13 seconds to see it playing..... getting ANGRY? ... I KNOW !!!

    Matrox support said "It's normal...."
    NORMAL ?!?!?!? Yes I know that the Marvel G-200 is not comparable to cards like MiroDC30+ or AV-Master 2000... but HAVE I TO USE JUST AVID CINEMA TO WORK FINE? :-(

    I work in a computer shop and i installed other Marvel G-200 and G-400 on different PCs... ALWAYS the same problem...

    I already tried new installation... with NO OTHER CARDS on my PC ... Win95B, Win98, Win98 SE... with MINIMUM NEEDED DRIVERS...
    Nothing....

    So... Since Avid doesn't have this problem... I am thinking it's something about drivers ... OR IS THE MJPEG CODEC so slow to get initialized ? ( I mean THE HARDWARE...)

    If this is HARDWARE limitation, i think i will change my Marvel with a MiroDC30+ or AV-Master 2000... by the way.. any suggestion? Which is the "better" ? ;-)

    Thanks for any answer.... and sorry for the "LONG" writing :-)

    My thoughts exactly, well almost.

    I have the same stalls with Premiere 5.0 and 5.1. Although it doesn't happend every f***ing time. After having waited for the first frame to appear, every other click on the timeline gives frame instantly - however, do something else like cut, paste, import file, open a dialog box etc., which doesn't have anything to do with displaying MJPEG frames, and you're back at square one, one click on the timeline and it's TACC-time.

    Annoying to say the least.

    It "feels" (like marcop said) like it's the hardware codec communication that cuases the delays. Same thing when opening a MJPEG movie with Media Player 5.0 - 6.4. TACC-time.

    Does somebody have any explination? Anybody?

      Did you try reading the sites "Tips&tricks" section ? There are a few tips for Ulead.

      Try double-clicking a clip to bring up a scratchpad window, that will keep the codec open and allow you to scrub instantly. There's also an INI entry that works for some folk.

      I think that the reason Avid is so fast is that it doesn't use MJPEG at all internally, it uses Quicktime instead.

        That INI trick from the readme used to work for me, but it quit upon moving to Win98SE and my PIII 550 (whichever caused the difference). But using it, I could begin scrubbing on the timeline and wait significantly less time for the results to come up.

        Anyone know why it doesn't work anymore?

          Hi Fluggo,

          Probably the OS although who knows. I never got it to work for me but I know others for whom it turned darkness to daylight.

          Opening the scratchpad works fine here though. Once you've opened it you can move it out of the way if you don't want to use it, but it keeps the codec open.

            You're saying then that if I leave a stray scratchpad window open, I can scrub on the timeline w/o delays? Won't there be a fight for use of the hardware?

              Yeah I read time ago about the "scratchpad Window" tip... and i tried it already.
              Well... the tip "works" but not at 100%...
              I mean, i can now click on timeline and get instantly the frame in the preview window,
              but it still "freeze" for 5-10 seconds when starting a preview (after working on the timeline) and vice-versa ( = delay clicking on the timeline after a preview).

              Well... I think this is the "best" we can get from the Marvel, right? :-)

              Thanks for your replays.
