How to change audio bitrate?

[Slogra]

I just made my first mpeg2. That was easier than is thought :D. One little question though: How do i change the audio bitrate in TMPEG? It is 128kbps by default and i can't seem change it at all (the dropdownlist is grey).

Also I want to make the top 4 pixels black, because there's some flickering at the top. I don't want to crop/resize things, because the video is interlaced. But how?

And one more question: What's the difference of Motion estimate search and Highest quality motion search? Does highest quality really give you the best quality or are there some disadvantages (besides encoding speed)

Thx

Use Unlock profile in Extra subdirectory.

I reckon that there's an AviSynth filter that can create a mask to cover some part of a movie (not crop or resize, just cover). I can't remember though what it's called :p

That filter (actually a function) is called Letterbox. See the Avisynth docs (supplied with the latest version, 2.05) for details. It's very useful in VHS captures.

I'll look into it.

And yep, the unlock profile worked :). What bitrate do you recommend? I've got no idea how good/bad MPEG layer 2 is. 128kbps definitely sounded too low though.

192 or 224kbps is good enough but if you want to save a bit of space you can set a bit lower (I presumed that you're doing SVCD) ;)

With normal film (that is sound with a stereo effect not too pronounced) you can use 128k with JOINT-STEREO (maybe loosing some surround information!).

dual - encode both channels seperately
Stero - encode both channels nearly separately
joint stereo - encode the sum and the diff of the two channels and spent bitrate where needed, so when bitrate shortage would occur the audio gets "more mono".

Also: NEVER USE THE INTERNAL AUDIO ENCODER (use ssrc and toolame)

Ok, i used Besweet to create an 44100hz 192kbps mp2 file. Now i want to multiplex it with the mpg file but there is one problem: The audio file should have a 40ms delay, but the audiotools of TMPEG doesn't seem to support delay when i want to multiplex audio with video.
What program should i use to multiplex it with the correct delay?

[Justinus]

AFAIK bbMPEG does this job ;)

Also you can use BeSweet to correct the delay time before transcoding as well. Read this (http://www.doom9.org/ac3tomp2-long.htm). Some part of this guide explains how to set the delay time for audio.
