JuliaCon Global 2025 videos will start releasing today

JuliaCon 2025
1

JuliaCon Global 2025 videos will start releasing today (September 17) on a rolling basis. Videos will be uploaded in large batches as unlisted over the next ~week (due to API rate limits). At the time of upload the video URL will be added to PreTalx as a resource of the submission. This link will be on the public facing page and should remain stable , so you may use that link to share the video etc.

Videos will be released or made public at a rate of ~3-4 videos per day. This allows The Algorithm to give everyone’s talk a fair shot, avoids spamming ~250 videos at everyone’s subscriber feed, and generates much more interest in each project than one massive premiere.

Please bear in mind there may be technical issues along the way, we thank you for your patience.

FAQ

FAQ:

  1. What are the video thumbnail backgrounds and why are there three different versions? These are thumbnails generated by Cormullion and have no other meaning. If your video has a red thumbnail instead of a blue one it simply means the random number generator rolled a 1 instead of a 3!
  2. Can I upload a custom thumbnail? We discussed doing this last year and it’s a project I very much want to allow in the future, unfortunately for bandwidth reasons (and the difficulty in doing this after the conference) we couldn’t do it this year. This is something I hope to work with the Global 2026 team on as part of the CfP process. As I’m sure you all know custom thumbnails are a big deal for The Algorithm™
  3. My video isn’t uploaded yet? If you don’t see a video link on your submission (on PreTalx) within the next 14 days please email raye@julialang.org.
  4. My video isn’t public yet? Videos will be made public on a relatively slow rolling basis for the reasons mentioned above, this process is mostly random.
  5. There were no videos made public today? If there is a gap in videos being premiered or made public it is likely due to a cron job error. Unfortunately we cannot schedule videos for premiere with YouTube which are unlisted, so instead I am running a cron job on an old MacMini. I will try to keep an eye out for this
  6. Why does it take 2 months to upload videos? Professional editing takes time, as does cleanup on our side by volunteers, we have no dedicated AV team or chair. Eduroam at this location is quite slow, and splitting videos is a time-consuming process. If you’d like to help out with AV next year for JuliaCon Global 2026 Mainz please let us know! We’d love your help
  7. Why are there ads on my talk? YouTube inserts ads regardless of any settings we can change. We do, however, have the videos set up for monetization which helps ameliorate a very small amount of the costs of the conference. We have no control over the content, except that we have tried to disallow all ads which may be considered harmful or unfriendly
  8. Who did the recordings? James Ferris and his lovely team at https://www.massivepgh.com/
  9. My name/talk title is misspelled in a thumbnail, title or description, or there is a missing character?! Please reach out to me on Slack or at raye@julialang.org. My sincere apologies fonts are hard!

FAQ item 10. (Which should maybe not have been hidden.)

Thanks for this, I always look forward to have individual videos of the talks because it’s way more convenient for me to select and create a watch list than navigating the planning and lives…

If possible, Please release conference videos such that slides occupy maximum possible space on screen so that content is clearly visible. Sometimes i find difficult to read content on my 16-inch laptop.

This is more an issue for the presenters themselves than for the videos. Some presenters use text sizes and graphics that are readable on good quality displays and live projection but suffer under video compression and after downloading.

What’s up with the uploads? And will there be recordings from JuliaCon Paris?

11

There are recordings from Paris, I’m just waiting for access to the YouTube channel to start uploading them, otherwise they’re all ready

I was wondering the same thing. It looks like the last upload was 9 days ago, and only a small percentage of the JuliaCon 2025 talks have been uploaded so far.

All of them are there unlisted. It seems like someone was putting them out manually. Youtube has a scheduling feature so I can schedule say 4 to come out every day, can I just do that in 15 minutes and then this is all fixed? I’ll work something out with @rayegun and get this going.

I’d also love an invite to upload the Paris ones! I gave my Gmail address in a Slack DM but I’m not sure who can grant me access beyond Raye

The conference was already three months ago, there are 250 videos I think I read somewhere? So four a day is still two more months for some videos to appear given that only a handful is on the main channel (the others are hidden in some playlist). I get the idea that putting them out bit by bit should keeps interest higher for each video, on the other hand, doesn’t interest go down the more time goes by? I’d probably just release them all at this point

Yes, I agree with you.

On the other hand, if you release everything at once your video probably gets lost in the noise. 250 videos is a lot

Well I put everything else in there to do ~5 a day which ends on November 6th. Let’s call that final, they now all have a schedule to automatically release unless anyone turns them off and I’m not planning to click a bunch of buttons to hyper optimize this.

@gdalle can then set JuliaCon Paris videos to shortly release after that (let me know if you need help with anything, or if you need the editor’s help with handling any difficult cases).

All right, that sounds reasonable, thanks!

We actually decided with @avik that the videos from Paris could start releasing in parallel to the Pittsburgh ones, so I’ll set a similar release schedule.

I’d love to know if there is a way to upload videos with their metadata in bulk. Sofar it seems this option is only available if we use Youtube Studio Content Manager, and it doesn’t look like we do?
How does one avoid inputting every video description and title by hand?
