As an organizer for Ignite Taipei<\/a>, there are plenty of technical things that I need to take care of. Managing people’s slides (plenty of fun there), runing the presentations (it needs the Ignite type 15s autoadvance), setting up web stream (where everything can go wrong), recording the talks themselves. One thing I haven’t done yet, is editing the videos.<\/p>\n

For all previous events we got some more experienced people to help out. The results were okay, nothing surprisingly great but plenty usable. It still did take a lot of time to do that, and I don’t like to ask people favours. Instead this time, for Ignite Taipei #7<\/a>, after almost a month of procrastination I decided to do it myself. Ignite is an experimental ground for me, where I try a lot of things I think about startups (even if it is a non-profit organization, it can have a startup like “organization”), and I thought if I was a CEO I would make it such that “the buck stops<\/a>” really here with me. Have to experience the work myself to be able to find better people doing it later. And I like video editing (from the good-old DVD ripping days, that came really handy this time as well).<\/p>\n

Recording<\/h2>\n

The recording was done with my Canon EOS550D<\/a>. When I got the camera, I could have gotten a 600D, but I thought “I won’t be using this for videos!” Duh! Now I have to put up with freaking large files, because 550D cannot compress them on the fly. Also, need to check whether I can get better SD cards, because at 1080p it broke the recording last time (that’s why the Ignite #6 videos are still not edited). 720p (at 50fps) seemed to work somehow, and looks good too. Will try to fix that still in the future. Now I have a GoPro Hero3<\/a>, that \u00a0can do 1080p without even breaking sweat, and I plan to use that one for the next Ignite.<\/p>\n

Title screen<\/h2>\n

A video starts with good title screen. Previous editors could manage animations and all the works, which I didn’t have any idea how to do this time, so just keep it simple: a static page. But still have to add my own spice: not just a simple title and header, but something good-looking, and expressing the spirit of our organization. So got a cool HDR photo<\/a>\u00a0of Taipei City (well, actually Zhonghe, the suburbs to the south)\u00a0from my friend, Chia-Da Hsu<\/a>, tuned it a bit to be a background image, and plugged it into Inkscape<\/a>.<\/p>\n

\"Editing
Creating the video titles in Inkscape<\/figcaption><\/figure>\n

I like Inkscape a lot, open source, capable, fun.<\/p>\n

Put in the background, position the text. The font used by Ignite, and thus for most of our own text is\u00a0Insignia LT<\/a>.\u00a0To make it more readable (20% gray setting), make a black outline to the text: Copy\/Paste in Place\/Stroke paint to black\/Make it thick (20px thickness for us), and blur with a suitable parameter value (was 2 for us), then move the layer one below. Voila, outlined text, drapper.\u00a0Just had to make one, then replace the text (and recreate the outline).<\/p>\n

Editing<\/h2>\n

I needed to put together the video with the slides, side by side, with synchronized timing, so it would look similar to the original talk. First, I needed to get the slides in image format, that I keep doing with ImageMagick, whit this script:
