Kdenlive Multi-Thread Render Performance Test Result (see description text)

This is a video I rendered multiple times with different threads= parameters, to measure the impact of multicore rendering. // The game being played is // The results are:
threads= Average (s)
1 362.54
2 230.01
3 218.33
4 216.78
5 215.74
6 215.79
7 215.76
8 215.55
9 215.83
10 216.32
11 214.34
12 215.70
on the following system:
Distro 4.1.13-1-lts x86_64
Mainboard FOXCONN A7GM-S 2.0
CPU AMD Phenom(tm) 9550 Quad-Core Processor
4 x 2200 MHz, 64-bit
RAM 7.8G
Video Advanced Micro Devices, Inc. [AMD/ATI]
Cape Verde PRO [Radeon HD 7750/8740 / R7 250E]
OpenGL 4.4.13416 Core Profile Context 15.20.1013, GLSL 4.40
GCC gcc (GCC) 5.2.0
using three render runs with the following software:
ffmpeg 1:2.8.3-1
mlt 0.9.8-3
kdenlive v15.11.90-55-g8580c88 * master
Which means that using more threads than available cores seems to not have a speed increase for this particular (rather simple) project on my particular system.

I ran the tests overnight on a freshly rebooted system with no busy services running, so the conditions were similar for all render runs.

Other parameters were: PARAMETERS_0=”-pid:10815 in=0 out=2541 $MELT atsc_1080p_25 avformat – $SOURCE_0 $TARGET_0 properties=x264-medium preset=veryfast crf=20 ab=160k real_time=-1″

  • Where are the results in this video? Just the raw test-material without any information does not help anybody. 🙁
