Veronica: heyo, I sent you the files by wetransfer
Erica: cool, thx!
Veronica: let me know if they work ok
Erica: yup
Erica: hey, the video file has some artifacts at the beginning
Veronica: what? 
Veronica: <file_gif>
Veronica: i watched it through before sending :-/
Veronica: oooh, ok I see now
Erica: yeah, could you please reexport it?
Veronica: yup, on it
Veronica: give me 30 min
Veronica: sorry :-/
Erica: it's ok, good thing we caught it now ;)
Veronica: :-D
Veronica sent Erica the file by WeTransfer, but Erica notices some artefacts at the beginning, so Veronica will reexport it in 30 minutes.
