Here’s some practical advice for speakers at our Open Source Design devroom at FOSDEM 2021.
1. FOSDEM organisers recommend using OBS to record and edit your talk video. This how-to gives useful advice. (https://dev.to/erikaheidi/how-to-use-obs-studio-to-record-or-stream-live-presentations-474j)
2. We recommend you recording and editing the video as soon as possible.
3. Don’t overload your slides. Make sure everything is readable when scaled down slightly. The 1280×720 video you send in might or might not be scaled down to fit onto a FOSDEM template!
4. Make sure your video presentation fits into your 20 minute assigned timeslot with room to spare for questions and answers. FOSDEM 2021 works on a strict broadcast schedule. The FOSDEM systems will ruthlessly cut you off at the end of your timeslot!
The Open Source Design group recommends you talk for 15 minutes and leave 5 minutes for questions and answers.
5. You must upload your talk video yourself to the FOSDEM system – we will send this to you in the coming days.
Your recording video format must follow these technical requirements:
resolution: 1280×720
frame rate: 25 fps
video codec: h264 video codec, main profile
video bitrate: <= 2Mbit/s
audio codec: aac audio codec
audio sample rate: 48 KHz mono
audio bitrate: 128 Kbit/s
media container: whatever is easiest for you
Helpful tip –
When you upload the video, the FOSDEM upload system will verify that your video file meets the above constraints. If it doesn’t, the video will be transcoded first, but this will take longer.
If you have issues with the video upload we recommend first comparing video details with the above requirements. If you need help, you can ask your Devroom Point of Contact.
