Totally support everyone in live format getting half cut (2,3,3)

I believe the answer is:

be all for

I'm a little stuck... Click here to teach me more about this clue!

'totally support' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'everyone in live format getting half cut' is the wordplay.
'everyone' becomes 'all' (all people).
'in' indicates putting letters inside.
'live' becomes 'be' (synonyms).
'getting half cut' indicates taking half.
'format' halved is 'for'.
'be'+'for'='befor'
'all' going within 'befor' is 'BE ALL FOR'.

Can you help me to learn more?
