How To Hosting Google Sites on own Domain

Create your website at Google Sites - sites.google.com

When finished design, Publish first. The website is now working on sites.google.com.

To connect this website with your domain name which you purchased from a Domain Registrar, do the following:
On the webpage on sites.google.com/, click on the Settings (Gear) icon
On the Settings dialog, click Custom Domains, then click Connect Domain.

Type in the domain that you own already.
It will check the validity of the domain. If ok, proceed to next step.

If you see this message "This domain is not verified. Please verify your ownership", then click on the link, otherwise skip this section.

This section will prove to Google you own the domain, by creating an extra TXT/CNAME record.
A new dialog will show two options: Domain or URL Prefix
Select the Domain option.

On the dialog: Verify domain ownership via DNS record.
1. Select record type. TXT or CNAME. I choose CNAME because my domain registrar only has this option.
2. Sign in to your domain registrar (e.g. CrazyDomains)
3. Copy the CNAME record below into the DNS configuration. 
i) CName Label/Host: asuiasiaafa
ii)CName Destination / Target: aoanofzdof.googlehosted.com
These two values (masked above) will be given by Google.
4.Press verify below.

Reminder: steps  2 and 3 must be performed on the Domain Registrars page, before coming back here to click Verify. By placing the above information on your Domain Registrar, this shows you have control of the domain name, hence proving to Google that you own that domain.

Follow the instructions below to complete the procedure.

Google Sites will show these instructions:
################
Connect to third-party domain registrar
- In a separate tab, sign in to your domain registrar’s website
- Go to your DNS settings
- Create a new CNAME entry
- Under CNAME value or alias, enter www
- In CNAME destination, enter ghs.googlehosted.com
- Note: Your domain registrar might require a full stop at the end
- Save changes
- Come back to this tab and click Done

Veed.io - An online Video Editing with AI-powered features

 Stumbled upon this online video editor platform while trying to condense video clips taken on my Google Pixel 7 Pro mobile phone. Few quick notes on some cool features that prompted me to share this experience here.

• Video Compression includes fps and framesize
• Free Account that is usable
• Upload and Download that are smooth
• Create videos by i) Recording ii) By Video AI (give a description and it produces a video)

Another reason that prompted this blog, is the rather un-intuitive layout and operations for the platform. But since it is quite a nice tool, I thought of giving more details here to make things easy for new users.

Video Editing Features:

FPS - for compression, use this to select a lower framerate. Choices are: 30, 25, 24, 10

Framesize - reduces the image to popular social media formats, eg: 

Timeline, splitter, cutter - for slicing and dicing

Voiceover

  

Some not so cool features:

- you get two free, anonymous, non-sign-in video uploads and edit. Then you need to create an account to do more. You can choose the free plan.

- The interface for the first two free videos are different. Subsequent videos need to be restricted according to the type of plan.

- Free plan features: watermark (based on your name), no privacy (anyone with the link can view your video), 720p, 10min duration per video, 1 GB per video, 20GB storage total.

Hints (for using a Free account):

- Give a short name, even a dot "." - so that the watermark is shorter.

- Permanently Delete video from your account if you want privacy.

How to start?  Create New Project

Must do this before it allows you to upload a video, and access the editing tools.

How to GET Video when completed?

Done -> Export

You don't download when you finished creating, editing, compressing the video. You have to EXPORT first. But how to export? You have to click DONE button, since there is no Export button. Then only click Export Video. The export process is where the final video is rendered, using all the changes that we specified.

How to download?

The typical Download icon does NOT download the video. You need to click on one of the 3 buttons below: MP4 (for video) or MP3 or GIF

How to get back to main page, after export and download?

Once finished, and you want to upload or start creating a new video, there is NO back to Homepage or project button. It seems stuck at the download page. So you need to click the VEEP word on the top left corner.

How to NOT Share?

For the free account, all videos are SHARED, unless you Delete Permanently.

Sharing happens automatically after the Export process is finished.

Below dialog shows different ways of sharing. 

Although the video is public, people can't see it unless you give them the link.
