For a video site (around 500 videos already published), I now have around 60 videos to be published. The next set of videos will come in 6 months.

Usually it is said that Google prefers fresh content and therefore publishing periodically is good. Yet, having more content on the site is also good.

I could not find a comparison between publishing in bulk or periodically.

So the question is: In terms of SEO is it better to publish all videos at once, or would publishing periodically for a longer duration be better?

**Edit**: In the light of the comments made, let me try to explain a few things I failed to clarify in the original question:

1. The content is related with health and is evergreen. It will not become obsolete in 2-3 months.
2. 60 videos might not seem to be a big deal when compared to 10.0000 pages but this website has a total of 500 videos. We are talking about more than 10% of the total content (At the moment it also receives relatively good traffic -around 500 visitors per day).
3. By "fresh content", I meant the website being updated regularly. My impression is that a website that has new content every week is considered better then a website that is updated once every six months, even if the total numbers of pages are the same.
