Is it correct to say “I’m finally putting out this video here because it’s long overdue”? Or can it be rephrased?

Your original sentence is correct and communicates your message well. However, if you want to rephrase it, you could try one of the following options: 1. “I’m excited to finally share this video with you, as it’s been a long time coming.” 2. “I’m thrilled to release this video now, since it’s well overdue.” 3. “I’m finally sharing this video because it’s long past due.” Feel free to choose any of these options or mix and match to create a version you like best!
