## My camera dilemma
I've used Sony A7 III for four years and need help choosing between A7R IV and A7 IV for video.
## A7R IV's 61MP sensor
The A7R IV offers a 61MP sensor for aggressive cropping while the A7 IV has 33MP.
## Video performance concerns
Higher resolution sensors can cause video artifacts and overheating when filming at high frame rates.
## LCD screen differences
A7 IV has a vari-angle screen while A7R IV only has tilting functionality.
## Real-world experience needed
I want to know how often video artifacts occur with each camera in real usage.
## Key takeaway

Higher resolution cameras can cause video artifacts but may offer better cropping flexibility
