Three QuickTime Embed Questions

1) Is there a max file size? I couldn’t get a 50 Mb movie to open. The code SEEMS correct: [qt:https://www.erniemunick.com/movies/i’llbeallright5.mov 320 256]

Only a big blue Q showed up

2) Do mp4s work in QuickTime Embed too?

3) I haven’t been able to center the movies I’ve gotten to open.

THANKS so much—sorry for the ignorance.
