For any issue that might happen with encodes, my goal (at least consciously) has always been to help preventing them in future, because actual reencoding is annoying, and we don't want bad surprises. So to make it most productive, here's how a good error report is done:
- Point out an error.
- Explain why is it bad (proofs, videos, images, examples).
- Evaluate how fatal it is, whether reencoding is outright required, or just desired.
- Come up with a solution proposal.
Then together we will figure out what will be documented about the issue in question (on wiki or in a dedicated thread), and I'll probably add the solution to the universal encoding script I maintain (partly for work, partly for reference).
Do not include emotions or accusation in your report, because that makes it less productive in the end. Don't assume the problem is already known and ignored.
Let's get info provided, workflow fixed, and reencoders motivated!
