Video settings, in depth
What are the right video settings on the a6700 — formats, profiles, and 4K 120p?
Choose the format by what happens after
XAVC HS 4K — smallest files, hardest on the editing computer. XAVC S 4K — the balanced default: 10-bit 4:2:2, edits cleanly, card-friendly. XAVC S-I 4K — every frame stored whole; the biggest files and the easiest edit. Default to XAVC S 4K and change only with a reason.
Log lives in its own menu here
Unlike the a7 IV, the a6700 has no S-Log3 profile preset — no PP8. Log shooting is a switch: Log Shooting → On (Flexible ISO), which applies S-Log3 with a LUT workflow; there is no Cine EI mode on this body. While Log is on, Picture Profile is fixed to Off. For footage that ships as-is, use PP11 — S-Cinetone.
4K 120p: slow motion, tighter frame
4K 120p is a regular Rec Frame Rate in Movie Settings — no S&Q detour. The trade: at 120p the angle of view tightens to ≈1.6× the lens marking (stills and other movie modes run ≈1.5×), so a 24mm frames like roughly a 38mm. Focus breathing compensation is also unavailable at 120p.
Buy recording time in Setup
Set Auto Power OFF Temp. → High and the camera tolerates more heat before protecting itself: Sony's guide rates roughly 30 minutes of continuous 4K at 25°C on High. Set it on setup day, not during the shoot.
Shoot the same 20-second scene three ways — PP11 S-Cinetone, Log Shooting On, and 4K 120p — and compare what each decision asks of you.
