What to expect before you start
Does CaptionBolt crop new videos automatically?
No. New caption projects keep the Original aspect ratio until you choose a Resize format.
Which aspect ratios can I choose?
Use Original, 9:16, 1:1, 4:5, or 16:9, then preview the resulting frame before export.
What if crop-to-fill removes important content?
Reposition the source or switch to a blurred or solid background so the full frame remains visible.
Finish the next take
