What does the sentence 该视频随即被上传至网络，转发量过万 translate to?

Question

I can't fully parse this sentence from a news article (warning: article describes violence):

该视频随即被上传至网络，转发量过万。
_{Gāi shìpín suíjí bèi shàngchuán zhì wǎngluò, zhuǎnfā liàngguò wàn.}

This directly translates to something like:

The above-mentioned video immediately [被 bèi (?)] upload to the Internet, and transmit to [more than 10,000 (?)]

I don't know why 被 is there; in the sentence it looks like it almost means "was". And I'm not clear on what 量过万 means precisely (literally it's something like: "quantity exceed 10,000").

Question: What does this sentence translate to?

The video was mentioned earlier in the article 录像中显示。。。, so I believe that 该 here means "the above-mentioned" (it doesn't make sense to mean "should").

Answer 1

Considering the context of the article, I would translate this as:

该....视频.................随即.........被上传....至....网络，......转发量...过万
the video (was) immediately uploaded to the internet (and) the number of shares/retweets/reposts (is) over 10k

该 indeed means "the above-mentioned" but in most contexts you can just translate is as "the". In normal spoken conversation we'd say 这个/那个.

被 is a passive marker, indicating that the subject is the receiver of the verb rather than the do-er, i.e. the video did not "upload", rather it "was uploaded".

至 just means 到 (to). It's the formal character, common in news etc, but in normal conversation we would say 到.

The character 量 means "quantity" and can be added after a noun. For example "转发" is "forward/share/retweet" and "转发量" is "the number of forwards/shares/retweets".

过万 simply means "over 10000".
