for looping it would be very nice, if the movie nodes would buffer the first frames when the file is comming to the end! i always have jumps and stuttering when it comes to the loop position! ok...i am playing 2 clips 2500*2000@25fps encoded with huffyuv in sync on a 5000px*2000px@50 output ....but except of the loop point it is running smooth

have you tried two overlapping movies, where each starts the other on Complete (and sets its alpha to 0 and the other to 100)?

Actually, when loop is on, we do buffer the beginning of the loop.

The new performance statistics in Ventuz4.04 is a bit unclear about that, but you can see the effect:

* load and play a movie (with a new movie clip node)
* switch on performance statistics and the movie section in the statistics.
* You should see 10/10 buffers if the movie is encoded correctly, number of buffers may increase for movies with long GOPs and out of sync audio.
* switch on loop
** the number of buffers doubles
** movie playback stops because Ventuz is buffering the begin of the loop
** If the loop property is checked when the scene is loaded, the beginning of the loop is decoded during scene-loading
** the beginning of the loop is not always the beginning of the file, you can have 4-point loops.
* if there is still stuttering, more buffers!
* This feature is only available when using the loop property, binding the movie to an animation works differently.

hi dierk

because i am playing both clips in sync i am using the movie frame node....so it would be perfect, if there would be an option for buffering the first frames

i tried to play same clips with the movie clip node...but it seems, that this node needs more performance than the movie frame node!....they are stuttering!

ah...yes i tried to play the movies in " a chain" but the playing movie is stuttering if the other is resetting to zero...i think because uf the buffering?!

haha....

we have build a dds sequence player. i have a dds sequence with a total res > 6000px*2500px running smoth in a loop with 50fps on a output res of 5000*2000px

but of course you need a good harddisk performance! dds in this res is ~7,5MByte....so at 50fps we have ~375MByte per second
