Hi,

I have big problem with the rendering for a few days. I'm trying to render in different formats. The project starts, then the displayed time is getting longer and comes to no end. I remember that first time to render was about twice as long as the length of the entire clip. I would like to work with kdenlive. Unfortunately it is not possible.


What can I do, that I can work fluidly?

Ubuntu 04.14; kdenlive 0.9.10

PS.: Sorry for my English

What type of source material?
What format are you rendering to?
What specs does your PC have?

most important: what are your MLT & FFmpeg/LibAV versions? Have your tried with an upgrade? (as there have been problems between MLT & FFmpeg recentrly, fixed now)
Did you check memory consumption if you are not facing the recent bug about memory leakage / process going to swap?

If upgrade doesn't fix issue, generating a script from the render dialog and running it from command line might help to get more information...

Not sure if I should piggie back on this thread or start a new one. When I render a clip out, it estimates a time to completion, say 30 minutes for example. The progress bar moves all the way to the end, and the time counts down as expected, until we get to the last 30 to 15 seconds. At that time, my CPU cores go from all 4 used at almost 100%, to only 1 core near 100%, and that last 15 to 30 seconds of video rendering take an hour. Is this normal behavior? It did this on v 0.9.8 and v 0.9.10, but its gotten much worse on 0.9.10 (much longer render times for the exact same content.)

Kdenlive:
0.9.10-0ubuntu0~sunab~trusty1 (trusty)

melt:
0.9.3+git20141005.22abed67-0ubuntu0~sunab~trusty1 (trusty)

LibAV:
6:0.8.10ubuntu0.13.10.1

Hi,

i had similar problems with the new kdenlive-0.9.10-0ubuntu0. However, purging libmlt (including kdenlive and libs) before installing the ppa-version helped for me:

Code: Select all

sudo apt-get purge libmlt6 -y && sudo apt-get install kdenlive -y

When now creating a new project, rendering with "H.264/AAC High Profile" works multithreaded again for me (as far as htop isn't a filthy lier).

Regards
