Chào mừng những người phát triển đến với hướng dẫn về công nghệ lễ hội Wikimania 2022. Trong tài liệu này, chúng tôi sẽ chia ra những gì bạn cần phải thiết lập trước cũng như các công cụ bạn có thể sử dụng để phát trực tuyến trong phiên của mình.

The Most Important Steps are your internet speed and browser. We recommend streaming or recording from a location that has a connection of 50+ mbps upload speed with a hardwired connection is strongly recommended. To check your internet speed, visit: https://www.speedtest.net. Google Chrome is the preferred internet browser for the festival’s viewing and streaming platforms. Please contact us if you are unable to access Google Chrome.

For a complete and quick reference synopsis of capabilities of each platform tool, and to help select the one best fitting your presentation needs, please see this comparison table.

The tools we recommend to use to stream your session for this year’s Wikimania include:

This will be the solution we are using for the highest level of production and with the language interpretations, similar to a ‘newscast’ format for few-to-many presentations available directly in the Pheedloop platform.  The Q&A chat box from the platform would be visible to presenters, but no on-screen video or audio Q&A from live attendees. All languages of interpretation would be combined into a single, attendee-selectable video player. On Demand Video of the session would be available within 30-60 minutes after the session concludes. There is an approximate 1-2 minute delay between the presenter live and the audience viewing to allow time for accurate interpretation and captioning.

1. You will be provided a web link from the speaker management team
2. You will be prompted to put in your name and email address. Please use the name displayed in the programme of events, and the email you used to submit your presentation briefings.

You must allow vMix to access your microphone and camera - you will see the below popup appear - please click "Allow".

If you are planning to use a Powerpoint or Keynote presentation, please submit that to our team and we will host it and provide you with a link to a remote slide advancer.

Note: Our technical team will help you connect to the slide clicker once you log into vMix - please ensure you have a mobile device or second browser tab handy for using as a clicker.

Once you've logged on, our technical team will greet you and ensure you are all set and ready to go. It's important that you log in ahead of time to leave time for any technical troubleshooting.

This portion of the document can be shared with your IT department if you are using a company or school-owned device. This will help get past most if not all firewall, VPN, and company computer issues.

Websites to whitelist: www.vmixcall.com and www.advanced.vmixcall.com

HTTPS: Port 443 TCP (outbound)

TURN/STUN: Port 10349 UDP/TCP (outbound)

Video/Audio Streams: Dynamic Port Allocation UDP - 49152-65535 (inbound)

vMix Call uses WebRTC which requires a random UDP port to be selected for each call (This is the Dynamic Port Allocation above).

This port is then used to send/receive video/audio between vMix and the caller.

Note: vMix does not provide or list IP addresses of our servers as these can change at any time due to redundancy and security requirements.

Therefore if it is not possible to open the ports above in general on a restrictive firewall, vMix Call will not be able to be used.

Allow-list Domains:

• *.clevercast.com
• *.vimeocdn.com
• *.google.com
• *.pndsn.com
• *.googleapis.com
• *.firebaseio.com

This is a tool that can be used for presenters that are unable to use vMix, or require ‘breakout room’ functionality, or audience participation and interaction on screen. This solution does not provide as high level of production value, as the format would appear as a traditional Zoom meeting. Remote interpretation is available, however multilingual recordings of these sessions would incur a 24-48 hour delay due to editing time. The Zoom window can be integrated into Pheedloop so the user does not need to click out of the platform.

Jitsi is a popular open source webconferencing tool that offers a great alternative to Zoom meetings. This is a good solution for smaller groups that wish to host an intimate and interactive presentation format. As it does not feature a native integration with the event platform, users of Jitsi sessions will have to click a link to join the meeting, and then enter their display name. There are no platform analytics available, no recording in the platform, and audience size is somewhat limited to ~75 viewers, due to the way Jitsi processes video. Unless you have your own Jitsi server, you may provide a Meet.Jit.si link to the organizers to add to the platform.

This solution should only be used for small group breakout sessions, Q&As, fireside chats, or casual conversations as they cannot exceed more than 25 people in a session at a time. Interpretation of these sessions is not possible.

There are three key mechanisms in a group to communicate with, built-in to the way PheedLoop Meet works in general. Text chat, video chat, and audio chat. Text chat is conducted via the familiar context-aware chat and presence monitoring system on the right-hand side of any group once it is entered. The text messages are permanent, which means anyone who joins the group can scroll through the discussion history. To partake in the video or audio chat, once inside the group, simply clicking on "Join Video Call" will pull up the familiar PheedLoop Meet interface, and allow attendees to join in a live meeting experience (allows for screen sharing also).

PheedLoop Meet optimizes the tiles and views of participants inside the video meeting interface depending on screen size and other factors. In general, the video meeting interface shows all participants in a gallery view, showing up to 16 tiles (video feeds) at one time. There can still be up to 25 participants in a group, but the first 16 to turn their video feeds on will show up until one of them stops sharing their video. Everyone can participate over audio as well, no limits there. If a screen is shared, then the video tiles wrap around the screen being shared, so that the screen share gets the maximum amount of exposure.

We recommend using one of the following platforms.

1. Riverside.FM - Highest quality but no virtual background
2. Restream - Add virtual background. Limited to 15 minute recordings for the free version.
3. Zoom - Lowest quality and add virtual background. Probably the best option for most users given widespread familiarity with Zoom and unlimited recording time.

For pre-recordings that are seeking increased production value, or with the complexities of multiple presenters coming on and off screen, we can also support facilitated vMix recording sessions with advanced notice.

As you prepare your presentation, keep these elements in mind:

• Where are you presenting (home office, work office, studio)?
• Are you standing or sitting for your talk?
• Do you have slides or videos that need to be advanced during your presentation?
• Our recording system does not allow for a virtual background, so please ensure your background is camera ready.

Set yourself up for success with the right equipment! Here’s the minimum requirements we recommend for a successful virtual presentation experience.

• Modern laptop or desktop with Windows 7/8/10, MacOS Sierra/ High Sierra/ Mojave
• External webcam
• External microphone (may require headphones for best audio quality)
• Browser requirements: Windows Chrome or Firefox
• Disable VPNs or Company Firewalls if possible
  • Those on company-managed devices with advanced security settings that block WebRTC communications may need to consult with IT
  • You may test your connection at https://test.webrtc.org/

• Wear neutral, solid colors – avoid plaid, pinstripe, heavy patterns or bright neon colors.
• A solid backdrop is generally most recommended – be aware of any doors, walkways, or other areas that other members of your home may interfere with your background.
• Do not sit with your back to a window, or where a window can be seen in the background of your camera shot – it will wash out the image.
• Look directly into the camera lens when speaking, not at the screen.
• Elevate the camera so the lens is at or slightly above eye level.
• Use a professional grade webcam if possible.

• Avoid typing or shuffling papers when possible.
• Use earbud-style headphones if you have them to ensure audio from the session does not bleed back into the microphone.
• A podcast style microphone is recommended – Blue Yeti, Audio Technica ATR2005 and 2100X are popular options.
• Always test your audio in advance and make sure you are happy with the quality.
• Built in microphones are not ideal, but provided there is no background noise or typing, they can be made usable.

• Sit where there is plenty of natural light (ie. facing a window, or in a brightly lit room).
• Do not sit directly under or forward of an illuminated overhead light. Backlighting is not ideal and can be unflattering or create a ‘halo’ effect.
• Makeup lights can be a great substitute for a professional studio light kit.
• Dimmable desk lamps are also effective for adding face-lighting if no other options are available.
