DVD to XVID - Anime

[psxiso]

Hi,

Can anyone give me an average bitrate setting for encoding Anime DVD-Video to Xvid?
I focus more on quality than size, so on average what bitrate is good for Anime?
I'll backup it on DVD-R.
I use AVI.net and Fairuse.


thank you.

You might want to encode at a fixed quant then. Bitrate depends on how compressible your source is, your output resolution, etc.

I don't want to use Fixed Quant coz it waste of MB while the gain of quality might not be worth it.
The source is Original DVD-Video.

I want to encode to 480x640, I want to get good quality but also want as minimum size as possible but quality is still my top target. That's why i want to set the bitrate for encoding.

And that statement makes no sense at all. Take celtic_druid's advice and try a few 1-pass encodes at various quants until you find the acceptable trade-off between filesize and quality. Or maybe try AutoGK, set the width at 640, and try various percentages for Target Quality. 75% is the default, and will give you excellent quality, but you may be satisfied with results as low as 50% or so.

Let say encode at 1200kbps for movie is acceptable for me. But encoding Anime which is cartoon, it doesn't require that much bitrate (1200kbps) for a good result, so encode at fixed quants is a waste of MB in my point of view, 1 pass encode is not for me, because everyone know encode at 2 pass output the best quality/size.
If i try various setting to find out my result then i don't to open this topic at the first place.
I open this topic to see which setting is most suitable for Anime and then i can adjust that setting to suit my need.

You have no idea what you're saying.

If you knew anything at all, then you'd know there is no single setting for all anime, no single bitrate. Are you saying that complex animations, such as recent Miyazaki films, will produce the same quality at the same bitrate as some relatively simple animations, such as Ah My Goddess or Inu Yasha stuff? Not likely. Different sources compress differently. And that's exactly why 1-pass VBR encoding is better, as it will produce the desired quality every time, even though you're not able to predict the final size. You said yourself that you focus more on quality than size. Perhaps you were mistaken. But that's all right, do it however you like. Ignorance is bliss.

You have no idea what you're saying.

Are you telling me that 1-pass is better than 2-pass in term of (quality AND size)? Lets me re-phrase that, In Quality AND Size.

If you read again, I ask for an AVERAGE setting, i never ask for a FIX setting as I already knew there's no FIX setting for every movie.
If you read more carefully, I hope to minimum the size if possible, so I would never use 1 pass encoding. 1 pass encode would be the last option I would use.

I don't like people like you in my topic, you focus more on what i said wrong (maybe because of little knowledge) rather than what i ask for help.
From the beginning to end, your answer is pointless, you basically explain each source is difference and need to encode with different setting.

So forget about it, go help somewhere else, I don't need people like you in my topic.

Perhaps you need to try some of the advice you have been given first. 1 pass quality based encoding will be a better option than 2-pass VBR encoding with the wrong settings. You can do some test encodes with a small segment and find out what works for you. Do some short quality based encoding, look at the results, and derive a suitable bitrate for a 2-pass encode if you believe it will give you better results.

However do not be fooled into thinking anime (or any cartoon based video) encodes well at lower bitrates. Something that mpeg based encoders (mpeg-1, -2 or -4) do not do well is anything with lines. Like jpeg, sharp edges of shifting contrast will quickly develop mosquito artifacts if the bitrate it too low.

Testing with short quality based encodes if the quickest way to find a suitable bitrate. If the size if fine and the quality is good, a quality based encode will complete in approximately half the time of a 2-pass variable bitrate encode.

If you ask for advice, then challenge the advice of (very) experienced people then you will never benefit.
