What is 2-pass encoding?

[plokm]

Sorry if this breaks the rules, but I can't find information on this anywhere. Can someone either tell me or direct me to a guide that tells me what 2-pass encoding is, and why I should use it instead of 1-pass?

Being sorry doesn't give you a pass.

Have you tried putting this into google.com "2 pass encoding"?

I didn't mead "sorry, i'm doing it anyways", I meant "I don't know if this breaks the rules, I don't think it does, but I apoligize in advance if it does".

As for your second point, I did try googling it, but I haven't found a good guide yet. I'll try your query.

@plokm, Please stop making silly threads all over the place. Everything you are asking for can easily be found if only you bothered a bit to search. :readrule:

I've just answered him in another thread... looks like crossposting on very similar/connected topics, and with each question a new thread pops out.

I don't mean to be annoying, I just didn't quite understand 2-pass encoding. I've been researching this all day, and I think I understand it now. Thanks for your help. This topic can be closed/deleted now.

The first pass of two-pass encoding determines how to best allocate the bitrate you set from the beginning to end of the movie and writes this to a log file. The second pass uses the information in the log file to create the actual movie. It produces better looking encodes because it predicts which scenes need more/less bitrate.

Easy.

THANK you, JarrettH, for giving me a simple explanation instead of complaining about my n00bishness.
