Ripbot Newbie! Please Help

[sbk]

Hi there, hope anyone can help me.
I have an uncompressed avi and want to make a high quality mp4 out of it.
But I don't know how to choose bitrate quality and high audio quality settings, I only see the options of 128kbps in audio and nowhere the video bitrate.


I really need some help, hope anyone can answer, thank you very much!

For video, set CQ to 18 or lower. Lower number always means better quality but overall size increases.
For audio, you can use this little hack

Thanks man! But I want this file to be used for cinema, the audio quality cannot go 320kbps?

Thanks!

320 kbps for stereo is an serious OVERKILL! AAC is more effective than old mp3. You do not really need such high bitrates for 2.0 audio.

Hi guys, I need to have the audio in 44.1K and in highest quality. With adobe media encoder you can put whatever settings you want. But in ripbot it encodes the audio with 48K and poor audio lossy quality.

Maybe do you suggest some other program for good encoding of mp4?

Thanks a lot!

I am "hacking" th e audio.cmd file to 320kpbs and the sample rate changes to 48.000 please someone can help me do it at 44.100 ?

Thank you!!!

I, for one, would like the choice of 192. The reason is that I make my MP4s for YouTube and YouTube will reencode them anyway and the better the quality to begin with, (maybe) the better the quality after they get their hands on it. I read the workarounds in the thread to which _Al_ linked and it all looked like too much trouble.

Any hope? Even something for the INI file that could be easily added to make it possible?

Thank you!!!

that can be changed in avisynth script that ripbot generates (properties/show script)

look for line: audio=ResampleAudio(audio,48000) or something, your script might be different and change it, or delete it (if your original is 44100 Hz) or just add your line in there , but place it above #audiodub line

this is why I kind of liked ripbot because I could custom change avisynth script pretty easy, it is part of its GUI

Hey Al, thank you for that! I found it myself after all.
What will happen if for example I put 321kbps or some other random number, instead of standard 128, 256 etc?
Will the video players in different computers will have problem?
Anyone knows?

Thanks guys

Not sure,
I use eac3to encoder and keeping those "dedicated" values .... 96, 128, 160, 192, 224, 256, 320, 384, 448, 512, 576, 640 ... why would I need something in between?

Choose one number as stated above, multiply it with 1024 and you get that value for Ripbot. Does it have any scientific background or specs limitation? I do not know.
