Single author big preview image size, blog post formatting

Hi
Is it possible to change or override the settings for the big preview image on one of my blog (news) pages?
I know I can change the media settings and regenerate the thumbnails for entry with sidebar, but that changes all of them I have obviously done this before since images on the other news items are different aspect ratios. Can you give me a quick help with this?
also – it seems the settings for the blog posts have changed – there used to be an area to choose format: image, video, url, etc. for the post but I don’t see that now – oh wait, if I choose it under the screen options I see it and then it disappears.

I woudld also like some help with the top post on the page below – I am seeing the feature image as well as the entire post, which also has a video. How can I have only the image on this page, without the video & text but with the image linking to the blog post and the post has jsut the video and text, like it does now? I have tried to use the “read more” break but it doesn’t work. How can I limit the text that’s on the blog page?
thanks
Nancy
