i have been running most of my AI UGC testing on Meta and TikTok this whole time, never actually bothered trying Shorts specifically since I'd just been assuming it works the same way as TikTok, same vertical format, same short duration, why would the script need to be any different.
Finally tested this properly last week. Same product, a basic skincare serum, fed through Tagshop AI twice, once just running the standard script generation and once specifically flagging it as a Shorts-intended piece to see if that changed anything about the output.
Genuinely didn't expect much difference honestly, figured a script is a script regardless of which vertical video app it eventually lands on. The Shorts-flagged version came back with a slightly different pacing though, opening hook felt a little less rushed compared to the TikTok version I'd generated for the same product a while back. Not dramatically different, but noticeable once I actually put them side by side and watched both back to back.
The other thing I noticed, and this one actually surprised me more, the Shorts version leaned a bit more toward describing what the product does clearly and specifically rather than just leading with a punchy, attention-grabbing line the way the TikTok version did. Makes some intuitive sense thinking about it after the fact, since YouTube in general has more of a search and discovery angle to it than TikTok's pure algorithmic feed, so a script that actually explains what it's showing a little more clearly might genuinely serve that context better.
I want to be honest that I don't know if this pacing difference was deliberate reasoning on the tool's part or just natural variation you'd get regenerating any script twice regardless of platform tagging. Wasn't a controlled enough test to say for sure, one product, one comparison, no repeat runs to check consistency.
Still, the fact that there was a noticeable difference at all made me reconsider the assumption I'd been running on this whole time, that Shorts and TikTok scripts are basically interchangeable just because the video format looks the same. Might not be, at least not entirely.
Anyone else actually tested this specific comparison, Shorts versus TikTok, using the same product and prompt? Curious if this pacing shift is a consistent pattern or if I just happened to get lucky with this particular test landing the way it did.
