Can I upload 16:9 video to TikTok?

You can, but it will be letterboxed (black bars above and below), making your video occupy only about 30% of the screen. Engagement drops significantly. Always convert to 9:16 for TikTok.

What resolution should I use?

For 9:16: **1080 x 1920** pixels. For 16:9: **1920 x 1080** pixels. For 1:1: **1080 x 1080** pixels. These are the standard resolutions that every platform accepts. Going higher (like 4K) is unnecessary for short-form social clips — it increases file size without visible quality improvement on phone screens.

Is 4:5 still relevant?

4:5 (1080 x 1350) was Instagram's recommended format for feed video before Reels took over. It still works for Instagram feed posts, but Reels (which use 9:16) now get significantly more reach. If you're producing for Instagram, prioritize 9:16 Reels over 4:5 feed posts.

How do I handle multi-speaker podcast recordings?

Three options, from simple to advanced: 1. **Full-frame** with blurred background — nothing gets cropped, both speakers visible 2. **Center crop** — works if speakers are near the center, cuts off speakers on edges 3. **Speaker-focused crop** — AI follows the active speaker, best quality but requires face detection For most podcasters starting out, full-frame is the right default. Speaker-focused crop is worth the investment once you're producing clips at scale.

Should I caption differently for 9:16 vs 16:9?

Yes. For 9:16 vertical, use 3-4 words per line at 56-72px font size. For 16:9 horizontal, use 5-7 words per line at 42-56px. The narrower vertical frame means fewer words fit per line, but the larger text is easier to read on a phone screen.
