Encoding: How to retain as much quality as possible?
Howdy,
care to enlighten me about when I should go for a KVCD and when for a KSVCD according to the source's original resolution, bitrate and audio in order to retain as much quality as possible? Just general/basic pointers please, mainly for single CD jobs. Also, could you please advise in which way the CQ settings affects the transcoding and encoding? Thanks a lot. Dc |

Use CQMatic. Encode mpeg1. Select nearest down horizontal resolution than your source. Use 128 or maybe 112 Kbps as audiobitrate. Dont' put more than 120 min in 1 CD80. Burn your final mpeg as your standalone accepts it, but I prefer SVCD no standard, even if mpg be mpeg1. CQ, constant quality, tell to the encoder what quality do you want, with a 0 - 100 scale in TMPGEnc. Encoder will keep this CQ, modifyng bitrate, so, in slow scenes, lower bitrate and visceversa. Take as a good CQ near 70 (but there is people that like results with CQ between 55 - 60) |
Thank you very much indeed for your tips :).
I do use TMPGE (both Plus 2.521.58.169 and 3.0 XPress 3.0.4.24). The vast majority of my sources are above the VCD resolution (352x288) so I'd prefer to go for KSVCD (352x576 right?), does it mean I have to encode to MPEG-2 instead of MPEG-1 or can I choose freely (using TMPGE I'd like to opt for MPEG-1 for quality reasons)? [Very stoopid question :oops:] As far as K(S)VCD's go what's the main difference between MPEG-1 and MPEG-2 (compression ratio? Selectable bitrates)? Also, what does CQMatic do for you? Calculate the best CQ for the desired output size or format (or both)? Fianlly, re: "Select nearest down horizontal resolution than your source." :?:, even if my source is for example 480x256 doen't a K(S)VCD alsways have width = 352? I'll appreciate any further piece of info and help, as well as the tolerance to my inexperience with the subject that it implies :wink:. P.S. I visited Mallorca just last month, beautiful vacation spot: I loved the Formentor seaside in the north, the nightlife of El Arenal, the gothic cathedral of Palma, the Cuevas del Drach and the Herbas liquor (dry) :D! |

In my previous post I said you "encode mpeg1". This is no matter what resolution you use. Most standalones accepts mpeg1 multiplexed and burned as SVCD no standard, with whatever resolution. [quote="DARcode"] As far as K(S)VCD's go what's the main difference between MPEG-1 and MPEG-2 (compression ratio? Selectable bitrates)? The main difference is the compression algorithm. mpeg1 is tuned to low bitrates. mpeg2 to higher bitrates. I thing if you go to 2 CDs, maybe mpeg2 give your better quality. Same with KDVD. But some people, masters as Dialhot, encode always (almost) mpeg1, even his target be KDVD. One reason, I think, is that TMPGEnc is the best encoder for mpeg1 . Quote:

Maybe you need to multiplex and burn it as SVCD no standard (mpeg1 or 2) as, for example my standalone don't like VCD with no standard resolution but like SVCD with whatever resolution (most standalones accepts mpeg1 or mpeg2 in this way). Quote:

He is right when he says that MPEG1 is better _for low bitrate_ and for this, tmpgenc is the best encoder. For DVD the bitrates are higher, so you can use an other encoder if you want. Quote:

Sometimes I don't understand well what is said in english language. Maybe for that, most of my encodings look as following: http://www.digitalfaq.com/archives/error.gif :lol: |

Could you wrap this thread up with a brief necessary tools and configurations list to get a decent KSVCD job done? Like: -grab these tools -run TMPGE -configure it as shown here http://www.kvcd.net/forum/viewtopic.php?t=2223 -use this AviSynth script [thread/topic?] -use HeadAC3che for audio with these parameters [thread/topic?] -watch movie :D Also, do you use CQMatic? If not what do you use? |
Follow this guide (sorry, it's french but fully illustrated).

DARcode, I know you are doing KVCD/KSVCD, but just to add one more info, it is interesting to get rid of the black borders only if you are doing KDVD and are encoding as anamorphic.
With an AviSynth script you can get rid with black borders to apply filters more efficiently, and put back the borders at the end for encode your KVCD. |

Anyway, I have both TMPGE and HeadAC3che, I guess I just need to get myself comfortable with AviSynth a bit and I'm set. I just wanted a good dirft/shortcut to get started like: configure TMPGE this way, use this AS script and encode/transcode audio like this with HAC3, basically just a a general configuration I can start experimenting with in order to find the settings which work best for my needs. |

And would MovieStacker make working AviSynth a little simpler? |
