![]() You can run the script multiple times to create different xml files, but if you do remember that you will need to change the value of the custom_effect_name variable each time to something different so you’ll be able to tell your gate weave custom effects apart. The value of the step_value variable determines how often the video frame moves. The variable value_string determines how much the video is zoomed in by initially. The script below is suitable for adding gate weave to PAL 4:3 video. #Synfig studio speed install#However, to make this as quick and easy as possible, I used a lovely Python module called pyfo which was developed by Luke Arno and did everything I needed.Īlthough you can install pyfo if you want to, there’s no need you can just extract the pyfo.py file and put it in the same folder as your Python scripts that use it.Īs you can see below, my Python script is pretty self-explanatory. Python comes with a selection of complex but hugely flexible ways to do this. For this task I needed to get it to write out an XML file. When I do scripting jobs I prefer to use Python if possible. So I thought I'd use this post show you the script I use to create “automatic” gate weave. Luckily, because the resulting gate weave custom effect is stored as a simple XML file, you can write a quick script to create Obviously, creating gate weave by hand for a long piece of video using the Kdenlive interface would take hours. The XML file created by Kdenlive for some manually created gate weave looks like this: When you do this, your zoom, keyframes and random movements are stored in the ~/.kde/share/apps/kdenlive/effects folder as an XML file. ![]() Once this is done, I could save this portion gate weave as a custom effect so I could re-use it: ![]() Keyframes added a five frame intervals X and Y changed randomly …and then moving the picture around randomly at 5 frame intervals. Video resized by 108% to zoom in on it slightly I did this by zooming in on my video slightly… I mentioned in my previous article that I discovered I could simulate gate weave manually using the Kdenlive “Pan and Zoom” filter. ![]()
