    Anyways, I've just installed Premiere Pro 4.2.1, I thought to check it out before buying it, but there is this lag-thing that keeps bothering me.

    My computer: Windows 7, Intel Core i7 920, 6gb DDR3 1333mhz, XFX HD4770 512MB, 1TB HDD

    For example, I've imported two pretty small AVCHD-clips onto the timeline, and when I zoom/enhance the timeline it lags.

    Does Adobe Premiere really use 64-bit? When I installed it - the Premerie installed itself into my (x86) folder in Windows 7 (which usually is a indication that it is a 32-bit software).


    Am I missing something?

  2. nope it's 32-bit.

    64-bit vs. 32-bit has nothing to do with how smooth you can edit AVCHD, it only allows more memory addressing

    CS5 will be native 64-bit

    Oh, okey. That explains it. Is there any date out for when CS5 will be released?

    EDIT: Nvm, googled the answer to my own question.

    AVCHD real time decode is slow even on an i7. This is due to the processing time required to decode AVCHD to frames.

    64bit has nothing to do with it.

    If you want it to go faster, you would first convert AVCHD to a digital intermediate format.

    Well, the thing is, it stopped lagging, it must have been something momentarily due to some other activity in the background.




    I'm confused now though.

    it only allows more memory addressing
    ^--Isn't this supposed to speed-up the software in general as a whole?

    What will be the strength of a Premiere Pro 32-bit vs. 64-bit in terms of the software as a whole?

  6. no

    it's only an issue when memory is the bottleneck (e.g. your project and it's effects take up say 5GB, and you have to use the swap file). In your case, the NLE decoder is the bottleneck. More memory won't make a difference, and for most people, you won't notice a difference at all.

    For example , in after effects, large renders and ram previews can easily take up 10-20 GB on workstations. A 32-bit OS can address only ~4GB (actually around 3.2GB due to bios memory addressing issues), so the system has to constantly swap memory from the storage system (e.g. hard drive or SSD)

    but for CS4 and AVCHD, it uses mainconcept's poorly optimized h.264 decoder , and does software RGB rendering which makes it very very sluggish. In addition, all NLE's add some extra overhead. If you play and compare the same clip in a dedicated media player and scrub or seek all around, you will notice it very snappy in comparision

    CS5 has a new engine, the "mercury playback engine" which uses Nvidia graphics cards to speed up editing with very low latency decoding. The demos and information and the net so far look very promising, you can search google for more info. CS5 is 64-bit only, and won't even install on 32-bit system

    Makes sense. Thanks for the elaboration!

    I have a new, small question. Is Avid Media Composor 4 - 64bit native? I have tried to figure it out by checking out their website and wikipedia, but failed.

    Thx!

    Probably not. It is only qualified to run on Vista 64 (Business and Ultimate) only. Not Windows 7.

    Avid Media Composer is very fussy about hardware and software. See the supported workstation list.
