Obviously, sometimes NO answer is an answer!
Best you can do is capture and THEN convert it (upscale). but... remember, this lens is what 1/8" You have to be REALISTIC with your expectations!
You posted in a thread yesterday where I provided a link to a free converter. Take the Vid and try using that (post edit). Also, you are recording Audio from the mic on the phone... how good do you think the pick up will be from even 10' away??? An audio Codec can only do so much.
Bottom line is that if Video recording is this
high on your needs list, you should not be looking to get it from a phone.
