>Full HD (1080P 50fps)... 1TB 5400RPM... most important to me is editing smooth experience
That video + 5400rpm will most likely not equal smooth editing

Ok, but talking about GPU.
Is there any main difference between 740m and 750m for my porpouse? (I know 750m is much faster, but will I feel the diference in editing?)
Do either of these laptops allow you to install a second drive? This ASUS G750 that I am using now does and it made a world of difference when I cloned the OS/Applications disk from the 1 TB 5400 rpm drive to a 128 GB fast SSD and installed a second 256 GB SSD (both are Samsung 840 PRO SSD's). Without doing that I am quite sure you will be disappointed.especially with your media from a DSLR. See the excellant article by Harm on laptops
Only ASUS allows to set secondary Drive instead of Optical Drive. But Asus is 1600x900 and not 1920x1080 like HP.
A drive in the optical drive bay is worthless, The interface in the optical bay is only a 3 Gigabit/second one and would defeat adding a high speed (6 Gigabit/second) SSD as Harm said on our web site.
Sure wish we could help but not with your current budget.
You want 16 GB of ram minimum. I would also wait a little longer and the 800 series GPU's will be available with the mobile units.
