Reducing file size best settings?

[arnbar]

I was using Shotcut with minimal adjustments to substantially reduce my Apple .mov files’ size by a factor of around 5-10 or so (to mp4) with very little quality loss. Then I screwed something up and can’t reset the setting. In Advanced, CODEC used to be at 55% quality and you could adjust that too. My only interest is in getting like a 1GB file down as low as possible (under 200MB).

Can someone please assist with High Quality settings and low file sizes upon export?

Since file size is more important than quality in this scenario, math can provide the answer. The edited video is 1h 30m 40s in duration, which is 5,440 seconds. The max desired file size is 3 GB, which is 3 GB * 1000 MB * 1000 KB * 1000 B * 8 bits = 24,000,000,000 bits. Divide bits by seconds to get data rate: 24,000,000,000 / 5,440 = 4,411,764 bits per second. Divide that by 1,000,000 to get megabits per second, and round a little for convenience. Total bit rate = 4.4Mbps Audio bit rate…

Also consider turning off hardware encoding unless you’ve got a GPU with 7th-gen NVENC or better (RTX 20xx+).
