Shotcut is amazing I still use it for work on a daily basis.

I use Shotcut for work, although we have a Premier Pro subscription. It’s perfect for my needs. We cut simple edits with no effects. I just occasionally need to be able to adjust volume and change video size / aspect ratio. Shotcut is perfect for my needs.

Speech Note for PC. FUTO for Android.
