    Hello all 🙂

    Since yesterday ive been having a problem in that my ram previews have been getting shorter and shorter and now im only able to render 2-3 seconds at a time which is infuriating, I have 2 gig of memory so I can usually get about 15 seconds in my ram previews.

    The area im previewing isnt particularly intensive, and i cant figure out why this is happening. If anyone can shed some light I will be very gratefull. Lowering the resolution is only adding a second to the preview time

    thanks in advance

    purge has indeed lengthened my previews thanks ;)!

    However now before it previews it says ‘locking exitisting frames’ for about 12 seconds before it even starts previewing :S

    🙁

    its also only playing the sound once in every 4/5 previews 🙁

    the inconsistencies with audio make me think it may be time to reboot…. but what source is your audio? is it an mp3 or part of a compressed media file? ae really doesn’t like compressed audio.

    it doesn’t like compressed video if it uses intraframe compression, either, like mpeg and many others. that could be part of your ram preview delay. also temporal effects like echo and frame blending can lead to delays, since ae has to load several frames to generate a one frame.

    it is a wave file, the sound issue has sorted itself out now, thanks though
