Check the exported video before you share it
Check your exported video before sharing it. Review the first and last shot, crop, text, sound and playback in the actual MP4 file.
The export deserves a review of its own. A timeline preview is useful, but it is not the file someone else will receive. Watch the downloaded result once at a normal viewing size and once for the specific details that could spoil the experience.
Keep the source project and original footage until that check is complete. A finished progress indicator is not a reason to delete the only copy of the material.
Start with the first and last seconds
Does the opening establish the subject without an accidental blank frame or unfinished title? Does the ending resolve, or does it stop in the middle of a movement? These are small parts of the duration but important parts of how the film feels.
Play the ending separately if needed. A fade or outro is a creative option, not a requirement. The useful question is whether the final image seems intentional.
Check every reframed shot
Watch subjects near the edges, especially in vertical versions of landscape footage. Inspect the full motion, not only the first frame. Confirm that a face, hand, sign or horizon is not lost as the shot progresses.
Compare the export against the intended frame rather than assuming the preview window always represented the final display. The crop calculator explains the geometry but cannot approve the composition for you.
Read the text as a viewer would
Check spelling, names, dates and the time available to read each title. Verify contrast against the actual moving background, not a single convenient frame. A small phone screen is a useful test when that is where the video will be watched.
Do not claim a platform's overlays leave a particular area clear without checking its current presentation. The exported image and the in-app viewing interface are different layers.
Listen to the delivered sound
Play the file through ordinary speakers or headphones. Check that the beginning and ending do not cut unexpectedly and that any recorded sound you intended to keep is still present. Confirm the intended music use is permitted for the destination.
Watch without sound too. A sequence should still make visual sense when someone encounters it silently, even if music adds an important atmosphere.
Separate download from publication
A rendered file, a downloaded file, an operating-system share sheet and a published post are distinct outcomes. Verify the actual destination after sharing. Processing by the destination can create another version worth checking.
For YouTube delivery, consult its official encoding guidance rather than assuming a preset from another service is equivalent. Use Stitch's workflow guide to keep the draft, corrections and final check separate.
