hi,

i was using kdenlive on my gentoo system in version 0.7.7.1.
the nvidia card i use is VDPAU supported and worked just fine with HD (720p/30fps) clips from my GoPRO camera.
a week ago i made a system update.
the kdenlive version is still 0.7.7.1 but my clips are stuttering at cut points.
transitions of two clips are massive stuttering even when i turn off video output in timelines.

i installed the current git and svn version with the install wizard.
now i have version 0.7.9 for testing but the behaviour is still the same.

can anyone help getting my fluent working system back? ;)

thanx.

Does it stutter in a media player when you play a rendered output?
It is very hard to give any advice; there are so many variables.

no, the raw material and the rendered files are running fluently in every other player.
even in the clip and project monitor of kdenlive they are shown normally.
only if there's a new video stream to show at a cutting point or a transition the playback in the project monitor and the sound is stuttering.

i really don't know what has changed in my system and unfortunately i can't go back to that point in the software because in gentoo systems a lot of programs are changing on an update.

if it helps, my system is
Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz
VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT] (rev a1)
Audio device: Intel Corporation Ibex Peak High Definition Audio (rev 05)
4 GB Memory
120 GB sata system harddisk
1 TB sata data harddisk
kernel: 2.6.34-gentoo-r12 #1 SMP Tue Nov 2 19:41:10 CET 2010 i686 Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz GenuineIntel GNU/Linux
kdenlive-0.7.7.1 or 0.7.9svn

my video files:
VIDEO: [H264] 1280x720 24bpp 59.940 fps 15437.4 kbps (1884.4 kbyte/s) or
VIDEO: [H264] 1280x720 24bpp 29.970 fps 8151.3 kbps (995.0 kbyte/s)

a problem of getting the videodata from the harddrive i can exclude, when i look at a system monitor the whole data is in memory and nothing is fetched from harddisk.

btw, a friend of mine has a similar new system (only AMD processor) but a brand new installed ubuntu (v10.10) system and suffers the same problems.

bye.

i can't solve my problem now, so i have a little workaround.
videos in dnxhd codec are shown fluently.
i convert my 720p h264 clips to 720p dnxhd (1280x720, 110000kb/s, 29.97fps) clips.
a big disadvantage is that my clips are now 6 times bigger on harddisk!
