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. :)

My initial Raspberry Pi 5 review and demo video is here:

Kevin’s Pi interview with Eben Upton is here:

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.

Thanks Chris for saving me from grim tv news for 20 min

[kevinmcaleer]

Great video Chris! Was honoured to be the second only guest!

[Mhm_Rhm]

I can not imagine the amount of time an energy that has gone to this video. Excellent job.

Still waiting for my pre-order to be sent. (Nov 12 2023)

[RoboNuggie]

Thank you as always for a great video. Top Youtuber and an all round great guy...

[jinty]

It's nice to see you having fun testing a new Pi Chris. I'm impressed with the efficiency of the official Heatsink/Fan which is what I've ordered with mine. The results of your tests are interesting, and it's nice to see that it is capable of video editing in a very reasonable time for it's size and capabilities. The video calling worked well too. Thanks for all of your efforts on our behalf, I look forward to seeing how things develop before the official release date. Best wishes until the next video 😃

This is really an incredible result for such a small form factor. I've decided to see where this leads in the next couple years. I might just be upgrading my pc to one of these! Great video, Chris.

[laynemccormic]

Appreciate your testing of passive coolers, the results look promising

[uncaringbear]

Thanks for another great video, Chris! The early tests at passive cooling looks really promising. I look forward to when you install an m.2 nvme drive!

[KOTZLOVRED]

Thank you sir for your video, great tests. Separately, I want to tell you that listening to you is the same as listening to the Beatles. Thanks again

[chriholt]

Very impressive for the 5! Plus I really enjoyed the collab with Kevin :)

[McRocket]

I find your unique delivery, very relaxing/comforting.
Like that of a quirky college professor whom is well liked/respected.

What a treat! I hope other YouTube viewers like this video as much as I do. I hope to see some sort of experiment using two cameras on the Pi 5! Looking forward to your next video.

This moment 5:42 reminded me of Spaceballs. (the scene where the heroes see their own movie) 😂

[ahmad-murery]

I missed the temperature tests too, and I miss Pi coding/projects as well.
I watched the interview Kevin did with you, and Kevin is a gentleman no wonder you Pi call him today.
Thanks Chris!

[pilotcritic]

I love numbers, charts, and graphs, so appreciated the temperature test very much.

[srtcsb]

The RPi 5 is looking very impressive. Good to see such quality progress (and excellent testing procedures, as usual 🙂). Thanks for another great video.

He truly is the Master. He's one the hardest working Youtubers on the platform.

[desktorp]

thanks for addressing the cooling situation.. always tends to be my biggest question on these devices

[legojenn]

I am happy to see this. I've been trying to buy a Pi4 for nearly a year after my Pi3 failed. I may skip to the Pi5 if it is available locally soon. Pi4s are only now appearing online locally for purchase.

Also, I'm happy to see that this version is able to work well as a general purpose computer, even if may never be required to do so by most users. As you have shown earlier refurbished x64 computers can do more for less, but the Pi is and will continue to be perfect for other specialised purposes.

Thanks again for another demo.
