    Bill are you using the rocket raid 2310?


    You say you have a 1TB RAID 0 is that 4 x 250 gig drives or 2 500's - I am using 4 x 500 sata 2 seagate baraccuda ES class drives and editing a 4 cam shoot in multicam edius 4.6 with full buffer and NO problems with full realtime playback in 1440 x 1080 50 i

    Check the performance of the raid remember 4 drives in raid 0 will be far faster than 2

    Not sure if you had 2 x 1tb drives that would be the case..........

    But my 4 x 500 gigs fly - using HDTACH they achieve over 280mbs in burst mode and over 250 mbs sustained data rate, more than enough for editing HDV in Realtime.

    Hope this helps

    AVI Files

    These are Canopus HQ .avi files. They are about 32 gigs per one hour tape. We got through the ceremony using multicam with a tolerable amount of skipping. The buffer stayed at 3/171 most of the time. We'll try turning on skip frames next time. That was dumped onto one track and the others turned off which plays flawlessly.

    On our way. . .

    I'm sure it would be easier for the system to handle except you'll need a crazy RAID setup

    Bill,
    Is your HD footage on your timeline m2t or m4v files? Or did you capture to Canopus HQ? If it's the latter, you'll get much more realtime performance.

    Wow, I did not know HD realtime performance was that tough.

    2 tracks without filters and only a minute of playback is pretty far from how I work with DV.

    What would/could one do to get better peformance?

    Is there a better CPU? File type ect...

    If you're editing in Multi Cam mode, you can switch the 'skip frames' option to drop frames, maintaining overall realtime playback

    How many HD tracks should I be able to play back?

    I'm working on our first HD project. It has 4 cameras throughout a wedding. Shift spacebar lets it play about 10-15 seconds before the buffer goes to 1/171. For 2 tracks, it will play more than a minute. In SD, I can easily play 7 tracks on this system. Have not put any filters on video or audio yet. I can mute video tracks and work through the project, just wondering what other work flow options there are?

    Asus P5W DH Deluxe, Core 2 Duo E6600, 4 gigs Kingston RAM, Quadro FX1500, 500 gb SATA system drive, 1TB RAID0 SATA data drive on RocketRAID card, XP Pro SP2, Edius 4.61
Working...
