Aha, now I know what that "Export XML" command is for! Here are my thoughts on giving up openshot-render in favor of melt:
1. Giving up openshot-render right now is like giving up nothing, since it does not work. 2. The export XML command offers to save in my "Desktop" folder, which requires me to take extra steps to select the right location. 3. melt's documentation (http://www.mltframework.org/bin/view/MLT/MltMelt) is obscure, compared to the output of `openshot-render --help`, but I was able to figure out an example that works for what I want to do: $ melt -consumer avformat:OUTPUTFILE.webm frequency=24000 channels=1 threads=2 PROJECTFILE.mlt (avformat selects avconv (or ffmpeg), frequency and channels are for the audio, and threads enables it to run on two processors; container format and video codec are implied by the output file extension, I think.) 4. It would be helpful to have a command-line tool to export an OpenShot project as Melt XML, and use it in a script which then runs melt to do the video rendering. In fact, I would like to suggest, if you decide to dump openshot-render, replace it with two command-line tools: one to export an OpenShot project to Melt XML, and one to run melt to do the rendering but with the same command-line options as openshot-render (because they are relatively easy to figure out, from --help and from inspecting what you do in the OpenShot render dialog). -- You received this bug notification because you are a member of OpenShot Bugs, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/729359 Title: openshot-render crash with "AttributeError: 'NoneType' object has no attribute 'settings'" Status in OpenShot Video Editor: Confirmed Bug description: When trying to render a project with openshot-render it crashes with AttributeError. The project.form attribute, which seems to be a reference to a GTK form, is never set when running from openshot- render. I was extremely happy to find the render-tool, as I've spent days trying to figure out a way to do a big batch job. Not so happy when I realised it didn't work. ;) 1) Ubuntu 10.10 (Also on 10.04) 2) Installed from repositories 3) Openshot-version 1.3.0 OUTPUT: $openshot-render proj.osp rendering options: container type: avi video codec: mpeg4 video bitrate: 5000000 audio codec: libmp3lame audio sample rate: 44100 channels: 2 audio bitrate: 128000 Traceback (most recent call last): File "/usr/bin/openshot-render", line 58, in <module> main() File "/usr/lib/pymodules/python2.6/openshot/openshot_render.py", line 37, in main bot.render() File "/usr/lib/pymodules/python2.6/openshot/classes/cli_render.py", line 239, in render self.current_project.GenerateXML(os.path.join(self.USER_DIR, "sequence.mlt")) File "/usr/lib/pymodules/python2.6/openshot/classes/project.py", line 258, in GenerateXML self.sequences[0].GenerateXML(dom, tractor1) File "/usr/lib/pymodules/python2.6/openshot/classes/sequences.py", line 226, in GenerateXML bg_track.GenerateXML(dom, multitrack, fps=fps) File "/usr/lib/pymodules/python2.6/openshot/classes/track.py", line 110, in GenerateXML current_frame = MyClip.GenerateXML(dom, playlist, current_frame, fps=fps) File "/usr/lib/pymodules/python2.6/openshot/classes/clip.py", line 466, in GenerateXML use_affine = self.parent.parent.project.form.settings.general["use_affine"] AttributeError: 'NoneType' object has no attribute 'settings' To manage notifications about this bug go to: https://bugs.launchpad.net/openshot/+bug/729359/+subscriptions -- Mailing list: https://launchpad.net/~openshot.bugs Post to : [email protected] Unsubscribe : https://launchpad.net/~openshot.bugs More help : https://help.launchpad.net/ListHelp
