Raspberry Pi 5: Video Editing, Video Calling & Passive Cooling

Raspberry Pi 5 tests, including video editing in Kdenlive, an HD video call in Microsoft Teams, and passive cooling experiments. Note that this video was edited on a Raspberry Pi 5. :) Thanks to Kevin McAleer for his assistance with the Teams call. You can visit Kevin’s channel here:    / @kevinmcaleer28   My initial Raspberry Pi 5 review and demo video is here:    • Raspberry Pi 5   Kevin’s Pi interview with Eben Upton is here:    • Eben Upton on the new Raspberry Pi 5   And Kevin’s Pi 5 interview with myself is here:    • Chris Barnatt on the new Raspberry Pi 5   KDENLIVE EDIT & RENDER TIME This video was edited in Kdenlive on a Raspberry Pi 5, which took 22 minutes and 13 seconds to render the final 20 minute 8 second output. This was far less time than I anticipated for two reasons. Firstly, my earlier test (which we saw in the video) had transitions as a far higher proportion of its total running time, and transitions take much longer to output. Secondly, Kdenlive seems to pause to do something at the start of a render, and the longer the video to be output, the shorter a proportion of the final render time this is. And so my initial estimate of just under an hour for rendering this video was way off. In case you are wondering, I did repeat my initial “standard” Kdenlive render test on the Pi 5 many times, and with lots of different settings -- and it always came out at 2 minutes 8 seconds, give or take a second. In the final edit, note that my opening and closing shots to camera were composited in Adobe After Effects on an i7 PC as they always are, and then put into Kdenlive on the Pi 5. The timelapse segments (eg in the cooling tests) were edited as distinct sub-edits, again as is my standard practice, but here in Kdenlive on the Pi 5. KDENLIVE DESKTOP SHORTCUT The icon I added to the desktop to launch Kdenlive using XWayland (so that it will work with the latest version of Raspberry Pi OS), was a link to a Bash script that contained the following two lines: #!/bin/bash QT_QPA_PLATFORM=xcb kdenlive The above script was created in Geany, and saved in the “Desktop” folder. Then, in the properties for the shortcut on the desktop (opened via a right click), it was set to “Open with Terminal”. You can call the Bash script anything you like. But I called it Kdenlive XWayland.
