just wanted to know about MacBook Air and Premiere Pro 23.0

It will work, albeit slowly. You see, I have a base-model M1 MacBook Air with just 8 GB of RAM, a 7-core GPU and only a 256 GB SSD. An external USB 3.2 Gen 2x1 or faster-interface SSD is absolutely necessary for any serious video editing work.

And my most recent PugetBench for Premiere Pro benchmark results with that base-model M1 MacBook Air are certainly no slouch for what it's worth: Running Premiere Pro 2023 and macOS 13.0 Ventura, it scored a 343 with the Extended preset and 467 with the Standard preset. Roughly speaking, it is in the same performance tier as a 7th-Gen Kaby Lake i7 quad-core CPU-powered Windows desktop PC that's equipped with a GeForce GTX 1050 Ti GPU.

Standard = 720x480 DVD Resolution
720p = 1,280 × 720 HD, High Definition
1080p = 1,920 × 1,080 Full HD, FHD, Full High Definition
4k = 3,840 × 2,160 4K, Ultra HD, Ultra-High Definition
