FOSDEM 2022 talk recordings

[Martin Decky]

Dear speakers,

the Microkernel and Component-based OS devroom schedule, as announced by 
Sebastian on Sunday [1], is now public [2]. We kindly ask you to check 
all the details that concern you and let us know about any discrepancies 
or issues.

Also, if there is any major change on your side (e.g. a need to cancel 
your talk), please approach us as soon as possible to give us sufficient 
time to respond to the change. Thanks in advance!

The next step for the speakers is to prepare and submit the talk 
recordings. Here are the guidelines:

(1) The deadline for submitting the talk recordings is **Saturday 
January 15th**. This is a soft deadline, but we strongly encourage you 
to at least make your first recording and submission attempt by that 
date, in order to iron out any technical issues, etc.

(2) The hard deadline for the recordings (according to the FOSDEM 
organizers) is Friday January 21st [3]. After that date, any recording 
submissions (even just reuploads for corrections) will be strictly 
limited to a few individual exceptional cases. The reason for such a 
strict deadline is the sheer scale of FOSDEM with more than 600 talks. 
Putting the deadline any closer to the conference date might overload 
the infrastructure and/or the organizers.

(3) Make sure that the length of your talk recording is strictly shorter 
than the length of your talk slot according to the schedule [2] minus at 
least 5 (preferably 10) minutes for the live Q&A. FOSDEM runs an 
automated broadcast schedule and recordings longer than the talk slot 
will be rejected by the submission system.

(4) Please adhere to the following technical parameters for the recordings:

* Resolution: 1280x720
* Frame rate: 25 fps
* Video codec: H.264 video codec, main profile
* Video bitrate: <= 2 Mbit/s
* Audio codec: AAC audio codec
* Audio sample rate: 48 kHz mono
* Audio bitrate: 128 kbit/s
* Media container: MP4
* Maximum file size: 1 GiB

If you deviate from these parameters, the submission system will attempt 
to transcode your recording, but your mileage might vary and the process 
might take significantly longer.

(5) Content hints: Please do not overload your slides. Use large fonts, 
clear diagrams without too much fine detail and avoid clutter. Make sure 
everything is readable even when scaled down.

(6) Upload: Please upload your recording through Pentabarf [4]. In the 
properties of your talk, you should see the "Pre-recorded Video Upload 
URL" link that redirects you to the upload page. There is also a video 
tutorial [5] from last year.

(7) It is up to you what means you use to prepare your recording. Most 
videoconferencing tools (e.g. Zoom, Jitsi) allow to do a solo call with 
screen sharing and provide a built-in recording facility. We have 
collected a few specific tutorials on the devroom CfP page [6].

In case of any questions or troubles, please do not hesitate to approach 
Sebastian and me. Thanks!
