Autofit and 2-pass encoding

[saber540ltd]

I tried a forum search but didn't find an answer to my specific question. If my asset is a .TS file from a HDTV program, and it's not long enough (55 minutes) to require an Autofit, is there still a benefit from using 2-pass encoding? Thanks!

P.S. I really enjoy this program and am really glad I registered!

That's really a question that can only be answered by your own eyes. That being said, I have been very pleased with one pass mode on even longer sources.

Thanks for the respone! But I'm basically trying to understand the process of 2-pass encoding. From what I've gathered through my searches, a short asset that doesn't require Autofit will be encoded at the highest possible quality within the DVD spec which is 9000kbs. And, unless I've misunderstood, 2-pass encoding will normally end up adjusting the bitrate so that it's higher on scenes that need it (a lot of movement, for example) and lower on calmer scenes. But if a short asset is encoded at the maximum bitrate of 9000kbs throughout, does that mean that 2-pass encoding will have no effect on it, or am I misunderstanding the process?

That is pretty much spot on. Only if you are down below the max would you see any benefit - for the reasons you cite.

Thanks for clearing that up. And thanks for a great piece of software!

I am having trouble with two pass encoding on a .ts (hdtv) program that is of any length. I get the memory error problem that others have posted. After searching this forum I have found that using two-pass encoding is causing the problem and that I should only use one-pass encoding.

I have the latest version and wondering what is the word on this problem, if any? Should the two-pass encoding work? Why is the option available if it shouldn't be used?

Thanks for any updates on this issue.
