Youtube allows uploading of full HD videos - 1080p. Dimensions are 1920×1080. This is 16:9 format, so you will need to crop your photos from top and bottom.

How can we communicate with YouTubers?

  1. Go to https://www.youtube.com/user/
  2. Click on the About tab
  3. Click on the Send Message button

Alternatively, we can use Google to search for their name, and if we get lucky, we find their email address.

How can we transcribe a YouTube video?

  1. Go to youtube.com/upload and upload your video file. If you have an MP3 audio file, you may use a tool like Windows Movie Maker, iMovie on Mac or FFMpeg to convert the audio into a video file before uploading to YouTube.
  2. Wait for YouTube to completely process the video. The machine transcriptions may not immediately become available after uploading the video.
  3. Open the YouTube video page in Chrome and look for the CC button in the player. If it exists, the transcribed audio can be downloaded as text.
  4. Press F12 on Windows, or Option+Cmd+J on Mac, to open the JavaScript console inside Chrome Developer tools and paste this code:
if(yt.config_.TTS_URL.length) window.location.href=yt.config_.TTS_URL+"&kind=asr&fmt=srv1&lang=en"

It will open the transcribed text of the uploaded video in the current browser tab as shown in this short video. Save the file with a .html extension and double-click to view the transcription in plain text.

The same trick can help you download the closed captions of any video on YouTube even if you are not the uploader. And you can replace “en” in the URL with “fr” or “es” to download the transcriptions in another language.

Another method:

  1. Open Google Doc using Chrome
  2. Click on the New button to create a new empty Google Document
  3. Click on Tools -> Voice typing
  4. Click on the Click to speak button (or the microphone icon that is displayed)
  5. Click on the Allow button
  6. Open another tab and start playing the video that you want to transcribe.

Another method is to play back the video on your computer but use your phone to do the transcribe:

  1. Open up a word processing or a note-taking application on your smartphone
  2. Press the microphone icon on the keyboard within the application on your smartphone to select voice input
  3. Position the smartphone close to your computer
  4. Play on the video on your computer

How can I create a youtube video from a bunch of slides and audio files?

I use QuickTime on my Macbook Pro. For each audio file, I can have a cover image. I need to figure out how to add a cover image for each audio file. Basically, I create a bunch of video files, one for each side / audio file, and then use QuickTime to concatenate these video files to produce the final video file, and then upload it to youtube. I end up using ffmpeg

How can we do a screencast with just Youtube?

Screencasting is simple. You download a software program, hit the record button and a video of your computer screen is created, ready for uploading to YouTube. There are a plethora of screencasting tools to choose from but you can also create screencast videos inside YouTube without requiring any desktop software. Here’s a step by step guide on how you can make screencasts of your desktop windows with YouTube.

  1. Log into Youtube using your Gmail account
  2. Click on the Upload button in the top right corner
  3. Click on "Live Streaming -> Events" on the left hand side. If you never done this before, YouTube make require you to verify your phone number to enable streaming.
  4. You are on the Create Event page. Give your screencast video a title, set the privacy of the video to either Unlisted or Private and click the “Go Live Now” button.
  5. This will open the Hangouts on Air page. You can click the camera icon to turn off webcam recording. Similarly you can toggle the microphone icon if you do not wish to record audio.
  6. Click the Screenshare button in the left toolbox and select a desktop window that you wish to record for your screencast. Remember that if you using multiple virtual desktops, it will only show program windows that are active on the current desktop.
  7. Click the Start Screenshare button to share your screen and then click Start Broadcast to start recording the screen. This is a private session so nobody can watch your broadcast while it is being recorded. When you are done with the recording, click the Stop Broadcast button.
  8. Go your YouTube video dashboard (youtube.com/my_videos) and you’ll see the new screencast video that you’ve just finished recording. You can download the video to your Google Drive or share it withe world.

The videos are recorded in 720p HD and this it would be a good idea to resize your desktop window to the 16:9 ratio before hitting the broadcast button.

To use YouTube as your screencast tool, sign in, click your profile icon in the top-right corner, and select Creator Studio. From here, expand Live Streaming, click Events, and select Create live event. Note that if this is the first time using this feature, you will need to verify your account.

Before you do anything else find the dropdown labeled Public in the Create new event window and change this to Unlisted or Private. You should also give the screencast a title. When you’re ready to begin, click the Go live now button.

The Hangouts on Air page will open (if this is the first time you have used Hangouts, a plugin will need to be installed). Disable the webcam if you prefer (leaving it enabled will display footage from the webcam – presumably your head – in the recorded video) and if you’re recording a voiceover later, you should also disable the microphone.

In the left-hand menu, find Screenshare, and in the resulting box, select the window of the open app you wish to demonstrate in your screencast, followed by Start Screenshare.

Click Start Broadcast to begin, moving your mouse around the desktop and demonstrating as planned. When you’re done, simply click Stop Broadcast and switch back to YouTube. You then have the option of sharing the video directly on YouTube (you may wish to alter the privacy settings from Unlisted/Private back to Public) or downloading it as an MP4 to edit it on your PC.

How can we stream live Google Hangouts on Air to YouTube?

Google Hangouts on Air and YouTube offer the benefit of recording your event while showing it in multiple places at the same time. Google Hangouts on Air let you share live events on Google+, YouTube and your website, which means your audience can choose how to consume your content. This is particularly important since many mobile users prefer to watch video on YouTube.

Before you can stream a Hangout on Air to YouTube, you have to create a YouTube channel and set your preferences. Below are the steps to create a channel and prep it to stream and record your live Google Hangout on Air event.

  1. Log into your YouTube account. Your YouTube login is usually the same as your Google account.
  2. Click on your profile picture in the top right corner of the screen and choose Creator Studio.
  3. Click the blue link to create a channel, and follow the steps. You’ll end up on the Videos page.
  4. On the left sidebar, go to Video Manager > Live Events. If you’ve already enabled live streaming, you can skip to the last part of step 9.
  5. Click Enable Live Streaming.
  6. Choose your country from the drop-down menu, then choose whether to verify your account via phone call or text message. Click Submit.
  7. On the next page, enter the code that was sent to you and click Submit.
  8. On the Congratulations page, click Continue and agree to the terms of service. You will automatically be redirected to your YouTube Live Events page.
  9. Click the blue button that says Create Live Event. Note: If you’ve already enabled the Live Event feature, you’ll see a different screen when you click Live Events in the left sidebar. This page will tell you that you don’t have any upcoming events and will ask you to schedule a new event.
  10. Click Schedule a New Event.
  11. On the next page, fill out the information about your live event. Enter the title and the scheduled time, as well as the description and tags.
  12. Select whether you want to share a message about the event on your Google profile. You can choose whether to make your event public, unlisted or private. If you want to share the link to your event with a specific group of people but not the entire world, choose Unlisted. Want to increase security settings even more? Select Private. Then the only people who can access the event are those you’ve invited. They’ll have to access the event via their YouTube account using their email address for verification.
  13. In the area labeled Type, make sure you select Quick (using Google+ Hangouts on Air).
  14. Click Go Live Now. Google Hangouts will automatically open up in a new browser tab. If you go back to the open YouTube tab, you’ll see that you’ve been redirected to the Events page of your YouTube Account.

If you accidentally close the Hangouts tab, click Start Hangouts on Air to reopen the window. If your event isn’t starting right away (e.g., it won’t happen for a few days or weeks), you can return to your YouTube Events page later and click Start Hangouts on Air when you’re ready.
