I've been using MacWhisper for this, with a huge variety of transcription options and things like speaker detection. It works great for all the 1 hour and shorter videos I've fed it, but does this have more to offer?
I haven't tried a 4+ hour video with MacWhisper but I presume that would work the same.
MacWhisper handles multiple-hour-long recordings just fine for me. I regularly process 4hrs on MacWhisper. Even whisper-cpp works fine these days for long recordings too.
Cool product, but it would be better if you stopped spreading misinformation to support it.
