GUADEC 2018 videos

The videos from the main conference room were recorded by the University directly. They are pending to be edited and are available at this shared GDrive folder.

The videos from the second room were recorded by volunteers at the conference. We need help to edit these videos.

If you want to help, great! Edit this page and write your name in the Editor field next to the video you'll work on, and follow the step by step guide below. Don't hesitate to ask in #guadec on IRC if you have any questions!

Editing HOWTO

This is a suggested method for editing the videos. Feel free to use a different editing program if you prefer, just make sure you follow the same format. You can use one of the 2017 talk videos as a reference.

1. Download and open kdenlive video editor (you can get it from Flathub for example)

2. Download video, audio and intro/outro from http://videos.guadec.org/2018/raw/

3. Create a new project, with:

• 1080p resolution
• 50 frames per second
• 2 video tracks
• 3 audio tracks

4. Import the video files, the mastered audio, and the intro & outros -- go to "Project > Add clip" and select the files. They will appear in the "Project bin".

5. Drag the video clips from the "Project bin" to the Video 1 track. Make sure you have the entire talk there.

6. Split out the camera audio, by right clicking the video track and selecting "Split Audio"

7. Sync the separate audio tracks with the camera audio. There may be a clapper board sound at the start, or you may have to use some other sound. Matching peaks in the camera audio with the microphone audio often helps; be aware that kdenlive has a zoom control in the bottom right corner of the window.

8. Once the audio is in sync, select all the tracks (hold CTRL for multiple select), and press CTRL+G to group them together.

9. Mute the camera audio

10. Edit the start of the talk: cut out anything before the introduction starts, and if necessary cut out the introduction.

11. Edit the end of the talk: cut out anything after the final applause (include the Q&A section if possible).

12. Drag the intro clip from the project bin to the Video 2 track so that it is at time 00:00. Move the talk itself so that it starts after 3 seconds, overlapping with the end of the intro by about 1 second.

13. Right click on the intro clip and select "Add Transition -> Dissolve". A transition object will appear in the timeline, which you should move and resize until it corresponds with the overlap between the intro and the talk. Right click again on the intro clip and select "Add Effect -> Fade From Black." Play the video from the start and make sure everything flows smoothly into the actual talk.

14. Move to the end of the talk, and drag the outro clip from the bin into the Video 2 track so that it overlaps with the end of the talk by about 1 second.

15. Right click on the outro clip and select "Add Transition -> Dissolve". Again, a transition object will appear which you need to resize and move appropriately. Right click again on the outro clip and select "Add Effect -> Fade To Black". Play the end of the video and make sure it looks nice, moving the outro to be earlier or later if needed. In general the transition into the outro should begin at the same time as the final applause.

16. Save the project! You are almost done

17. Click "Project > Render" and select WebM-VP9 format. Click the "More options" checkbox, then drag the "Quality" slider to give "Video: 38" and "Audio: 4". Then click "Render to file".

18. Upload the .webm file to some public storage (your GNOME NextCloud account would be a good place, although you may need to ask for some extra storage space). Update this wiki page with a link to the video. Mention in #guadec that there is a new video ready to be uploaded.
