loadram in Andrew Bensons movie bank patch does not work

hi list,

i was very happy to see the latest tutorial from Andrew Bensons,
which describes how to program an efficient movie loader.

everythin works fine, but when i switch between the movies the newly triggered movie stops for 7 frames. which meens a 280 millisecond freeze at every start of a new clip.

is that normal ?
or has someone found out a better solution ?

thanks in advance for any help

my movies are: 768×576 fotojpeg
my system is: latest Max5, macbook pro 2.16 GHz, 10.4.11
with external hd 7200

Does this lag also happen when retriggering a movie that had been triggered before or is it only the first time?

hi andrew,

thanks for your fast reply :-)
it seems to be a systematic bug.
the freeze is happening any time, triggering a clip.

downloaded the latest version of the movie bank patch.

very strange.

Hmm, works fine here on my machine. Do you get any errors? What sort of hard drive are you reading from? (disk speed, interface, etc.) Are all of your videos the same size and compression? Is anything else happening on your machine while testing this?
If the problem persists, try the attached version of the vps.mbank abstraction.

hello andrew,

testet your new patch.
the switching behavior has changed.
now i have the stillframes before the switch.

if i switch from movie_01 to movie_01
movie_01 with 5 stillframes at the end, then movie_01

the behavior at the original VPS-4 was
movie_01 then 5 stillframes at the begining of movie_02

MacBookPro2,2, mac os 10.5.8
all videos have the same size and compression 640×480, photo-jpg, 25 fps
disk speed 7200 over firewire 800
window size 640×480, moviebank size 640×480 uyvy
record settings 640×480 photojpeg

only max is running.
same behavior with and without recording.
