Hey there,

You can configure the width and height at Videos settings which is at Backend > EasyBlog > Settings > Media > General > Videos. https://take.ms/avZJK

Hello. I tested it.

1. Seems changes apply only for new addde post.
And old post still display another size because it's encoded...

[embed=videolink]{"video":"https://vimeo.com/373076642","width":"400","height":"225", "nocookie":""}[/embed]

2. Also player is not responsive -- on big screen it display with big height (for example I setup 800x600).
It reduse only width, but height is still. On screenshot you can see video 730x600.
I expected that video's height will be reduced too, like in EasySocial.

3. Also system display 600px height in Category (screen attached). https://test.stranakrovi.ru/horror/categories/2-review

Thanks.

That setting what I colleague point you to is set maximum video width and height.

For example :

1. If you set your maximum width and height to 700x500px

2. Then your blog video set to 400x250px, it will show as what you set from the blog post.

3. If you set your video width and height more than the setting e.g. 1000x700px then it will respect your setting what you set that maximum width and height, mean that video will show 700x500px.

Yes, for those existing blog post, you have to manually edit from the blog post for those width and height value.

2. Also player is not responsive -- on big screen it display with big height (for example I setup 800x600).
It reduse only width, but height is still. On screenshot you can see video 730x600.

That maximum width and height only configure for the iframe width and height instead of the player screen.

Unfortunately that is not possible to control this if the YouTube video display on the smaller area.
What we can do is make it show responsive if display the YouTube video on the smaller area.
