After 10 seconds of continuously using 'step forward' or 'step back' in multicam mode I start experiencing some serious video stuttering, however, when i just play (spacebar) the sequence, there is no stuttering.
3 avchd tracks, 1 wav track,
no effects on any tracks,
all media on internal 7200rpm HDD at about 50% full capacity
AMD Phenom II X6 1055T
8GB 1600 memory
ATI Radeon HD 5800 series
c: OS, Programs, Pagefile - 1TB 7200RPM
d: Previews, Media Cache, Exports - 1TB 7200RPM
e: Media, Projects - 1TB 7200RPM
Resource monitor registers a consistent 9MB/sec when playing (spacebar) sequence, but varies wildly from 0-20MB/sec when using 'step forward' or 'step backward'
Is this normal? any thoughts?
Do you know the technical difference between playing and stepping forward on a sequence? I'm interested in knowing why one would be so much more hardware intensive than the other.
When stepping forward, each frame has to be decoded without caching, because your next step may well be to step backward or some other action. When playing each GOP can be cached, so it is a lot easier on the system. At least that is what I'm guessing. Your CPU (AMD), memory (only 8 GB) and GPU (AMD) are not very fast, so on a fast system this may not be very noticable, but it will be on your system.
