Comment (by markfilipak):

 Well, pdr0, the thing that was missing was that to you the origin is a
 60fps camera output whereas to me the origin is a BD or DVD. So when you
 write about losses, you mean losses relative to 60fps samples. I read what
 you write and I try to relate it to BD & DVD video and I can't figure out
 why you seem so stupid. :) Hahaha...

 It's funny how a difference of perspective can cramp a conversation.

 Before I depart, I want to thank you: Thank You! and I want to leave you
 with something of value to repay your kindness.

 I write this as a 30-year documentarian: You are exceptionally patient and
 caring, but you could be more effective. I'll tell you how.

 Avoid object pronouns that, 1, refer forwards, even when the object
 (object noun or noun phrase) is the predicate of the same sentence, or 2,
 backwards to a previous sentence. In other words, use object pronouns that
 refer solely to a previous subject that's in the same sentence.

 For example, above I wrote: "I read what you write and I try to relate it
 to BD & DVD video..." I could have written: "I read it and I try to relate
 what you write to BD & DVD video..." Both are grammatically correct, but
 in the second sentence, "it" refers forward. Don't do that. A deferred
 forward reference is confusing. Likewise, don't refer, even backwards, to
 a subject that's in a previous sentence. Instead, simply repeat the
 subject of the previous sentence in the current sentence. Doing so will
 cause you to write a little more in the short run, but it will save you a
 lot of explanation in the long run.

 Likewise, avoid completely other object pronouns such as "this" & "that".
 The same is true of personal pronouns (example: "Roger and Bob ran because
 he was afraid" -- is "he" Roger or Bob or someone else? -- instead of
 "Roger and Bob ran because Bob was afraid"), but personal pronouns are not
 often found in technical writing.

 When I proofread what I write prior to submittal, I look especially for
 bad object pronoun references and fix them or repeat the original subject.
 I do that as a conscious step much as a coder scans for obvious syntax
 errors prior to compiling.

 Very Best Regards,
 Mark Filipak.
