A fairly belated response, but…
It’s probably your resolution:
When printed out, 1296 pt type should be about 18 inches high (depending on the typeface/weight, etc.), but if your resolution (image size) is something crazy like 10 dpi, then the type would appear tiny, because if you printed out a 2000pixel-high image at 10dpi, it would be 200 inches tall, so 1296pt type would, rightly, be tiny in comparison to the whole image.
Check your image size, make sure ‘resample image’ is OFF, then change the resolution to something more cromulent to match your final output – maybe 300dpi for print, or something in the region of 100dpi for video (not that the resolution – dpi – matters one iota in video – it just makes it easier to get predictable results when setting type in points!) One of my ‘pet hates’ is people saying “it’s for video, so make it 72dpi”. It depends how big yer telly is!
