Just adding a quick follow-up in case anyone else is experimenting with this too — I’ve been testing a few different export settings and found that vertical 9:16 aspect ratio with 1080x1920 resolution and 30fps works well for TikTok. Also, keeping bitrate around 5–8 Mbps seems to balance quality and file size nicely.
For creators working on more VFX-heavy or slightly mature Unreal Engine content that doesn’t always fit TikTok’s guidelines, I’ve seen some share their work on TikTok 18 — it offers more flexibility for showcasing creative projects without the same level of content restrictions.
Still curious if anyone has fine-tuned their export or post-process workflow specifically for mobile platforms.
