    Newb question: Why does Premiere appear to be loading footage into RAM when it “conforms” files?

    I have hundreds of shots, but importing ONE file costs me 1.5 gigs of RAM. After it “conforms” a clip, a process that spikes my RAM up by over a gig, I don’t get that ram BACK again.

    What could be going wrong? If it cots my system 1 gig of RAM per clip simply to have the footage imported, then I can’t edit my film.

    Hi Charlie,

    You didn’t mention your Premiere version. While not being a software engineer, I’m sure Premiere does load clip cache into RAM. Hard drives still have a much slower access time than RAM does, so depending exclusively on HD to store cache would not be very efficient. Many of us have between 8 and 12 GIGs of RAM, so 1 gig should not make much of a difference. I would recommend a minimum of 8GB of RAM for versions above CS4, and even more if you run After Effects.

    If that makes you feel better, when we first purchased our DDR3 RAM, it was about $250.00 for 4 GB, I’ve seen some around for less than 50 bucks. Yikes, that was a year ago…

    What happens if immeadiately after the clip is finished conforming, you restart Premiere? I imagine the RAM should get flushed, but the clip will not need conforming again.

    Hi Chris,

    Yes you’re right. Except there are a few hundred shots in the project and all of my RAM is used up by about 4 shots, then I have to get out of premiere before it crashes or I have to reboot my system.

    So I can conform four or five clips and then leave premiere and then come back and repeat this process. But it seems ridiculous.
