This needs an article - "a recommended default" or "the recommended
default" - unless you're going to rephrase further to something like
"recommended as the default". Also, why are you mentioning "default"
again immediately after having given it in the line immediately

I've never heard of "mismatch error" in the context of video encoding
before, and on brief consideration of the term I haven't been able to
figure out what it would mean. It may not be strictly necessary to
explain it, since presumably the subject is gone over in places where
people can find it easily enough online, but I thought I'd point the
fact out.

I'd rejigger the pauses here slightly - comma after the first "seeking",
and change the existing comma to a hyphen.

side of it.
