sooo, you might find this useful - i feel u on those web tools... they basically crash on 4K. unfortunately, it wasnt as good as expected for the price. i tried Topaz Video AI v5 but it was way too slow. id honestly just use DaVinci Resolve Studio 19 for the magic mask and audio isolation cuz its more stable for pro work. the Adobe Premiere Pro speech-to-text is actually decent for captions too. gl!

100% agree

Building on the earlier suggestion, I'm with you 100% on web-based tools being pretty useless for pro work... they just cant handle the bitrate of real 4K footage without choking. That said, in my experience, I'd actually disagree about switching your entire NLE over to Resolve just for those specific AI features. Over the years, I've tried many transitions like that and it usually eats up more time in learning curves and file management than it actually saves you in masking. I've found it's way more cost-effective and stable to look for dedicated plugins that run locally within Premiere. It keeps your project files consistent and doesnt mess with your round-tripping. If you're hitting walls, it might actually be a hardware bottleneck rather than the software itself. Most AI tasks rely heavily on specific GPU cores, so sometimes a hardware tweak is more reliable than learning a whole new app... anyway just my two cents from the field!
