download YouTube videos with Media Mister

If you search around, you'll find many suggestions online of how to download video from YouTube without purchasing a premium account for YouTube. Some of these work, and some don't. Some are some sketchy sites you should probably avoid. Media Mister is listed as a safe site in Norton Safe Search, and I've tested and confirmed it can be used to successfully download a complete video with audio.

Media Mister's primary function is to generate likes for social media content generators, but it also makes tools available to review social media data. Use the YouTube download tool here: https://www.mediamister.com/free-youtube-video-downloader

The site will give you the ability to download the video at different resolutions, or just the audio. For YouTube videos select the 360p option which includes the audio with the video. The video will open on new tab, and you just need to right click and download it. A video of an hour long can be downloaded in just a few moments.

What does in the p in '360p' mean? It does not stand for pixels - it indicates that progressive scanning has been used for the video - although a 360p video is 360 x 640 pixels.

360p videos are used on YouTube and other sites with streaming videos. A 240p video might appear on a mobile device.

Standard definition videos are 480p. High definition videos are those at 720p. 1080p is full high definition - the standard for Blu-ray.

You may also see a reference to 480i or 1080i. The 'i' refers to interlaced video - which was used for broadcast televisions. A video posted here on YouTube by Dans Tech describes the difference between the two types of video very well. An interlaced video shows video at a lower bandwidth by showing the even lines for a given frame in the first 1/60 of second and then the odd lines in the next 1/60 of a second. The image appears to be complete to the human eye.

In progressive scan, all of the lines are together. Progressive scan videos were used more widely after the emergence of modern computing because of the need for seamless motion on monitors.

Stopping audio feedback when sharing a video in Zoom

Working on a trial in federal court right now, and assisting with the courtroom electronic presentation. When doing the a/v setup, I learned a valuable lesson about how to prevent feedback. I had my laptop connected to speakers and monitors with a VGA cable fed through a HDMI converter to my laptop and separate audio cable - VGA will not transmit an audio signal.

I needed to confirm that I would be able to share a PowerPoint presentation in a Zoom session with a witness testifying remotely. Initially, when I tried to play a video clip in the PowerPoint I got very loud feedback - sort of like someone banging an industrial metal drum. The IT staff for the court helped me to discover a solution to the problem.

The first step was to mute both the mic and video on Zoom.

You can still play audio through the Share Screen function even if your mic for Zoom is muted.

The next step was to adjust the audio mixer for Windows so that only the feed for the 'headphones' - the port where the audio line was connected - and the sound for PowerPoint was enabled. System sounds, sound for Zoom itself, and sounds for all other applications were all muted.

. . . scroll back and forward in the Volume mixer to find other applications you may need to mute.

Finally when sharing the PowerPoint in the Zoom session be sure to click the option to share sound and optimize video.

K-Lite Codec Pack

As previously discussed in the Tip of the Night for December 7, 2019, a video may not play in an application or on an operating system, unless the necessary codecs are installed. A codec will uncompress a video file, so it can be played. Typically video files are compressed to save storage space at the loss of some of the original resolution. These are lossy video files.

The K-Lite codec pack, available here, https://codecguide.com/, will allow Windows to play a wide range of video and audio formats. It should allow Windows Media Player to recognize most video and audio files. The Ogg video format (with an .ogg, .ogm or .ogv extension) is actually a container file which must be uncompressed before it can be played. It is not supported by Windows Media Player. See the list of supported files posted here. If you attempt to play such a file in Windows Media Player, you'll get an error like this:

If you prompt the Windows Media Player to try it, you'll get this result:

After the K-Lite Codec Pack is installed, an OGG file should play in Windows Media Player. I tested this on my PC tonight and confirmed that installing the pack made the difference.

Another common format video format which doesn't work with Windows Media Player is are Adobe Flash videos with the .flv extension.

However, if you are presenting videos with IPRO's courtroom presentation software Trial Director ,be aware that the K-Lite codec pack can cause problems. Tech support for IPRO warned me last month that the K-Lite codec pack has been known to interfere with the performance of Trial Director. It's usually recomnended that Windows Media Player be set as the default application for video and audio files when using Trial Director.
