Burning right now...
I'll let you know in a second or two... |
YES :!: That was it. Works like a charm :wink: Damn, this looks good. The quality of QuEnc 0.45 is really something else :!: :)
Thank you for the tip Kwag. |
Now try encoding the complete movie using CalcuMatic (or other bitrate calcs) to get your average bitrate. Then see if the final size matches closely the wanted size ;)

Kwag, the GOP 3 Frames issue to me seems like an Scene Change issue.

Anyway, QuEnc made a lot of progress but it's output is still under the quality of ffvfw (ffdshow actually) and the gain in speed does not pay the quality loss. But it's still 0.45 release... Edit: Well, I forgot, another big advantage of QuEnc is VBV compliancy. I wonder why ffvfw is the only libavcodec incarnation thas has this issue, why milan does not fix it... marcellus |
As I got the actual QuEnc vers. .... where can you see a command line option??? My vers. does not show one, neither shurely to alter it as its not avaiable.
He should offer more options of ffmpeg in his GUI .... for example processing interlaced sources. |
Man, it's very fast!!!!! :D 8)
I am currently encoding a AVI movie using the latest Dialhot v4 script: With Trellis, GOP 18 and KVCD Notch I get 19.5 fps, Without trellis, it goes up to 24 fps (realtime!) Amazing speed. Can't comment on quality yet, let's wait for the outcome. I am doing 2 pass VBR. I had previously encoded this movie using CCE so I'll be able to do a good comparison. @incredible: Do this: QuEnc /? A window will pop up with command-line options. |

Normal GOP: IBBPBBPBB.... Screwed (example): IPPPBBPPPPPPBBPPP.. |

But the way I see it, I find QuEnc much more simpler and flexible than ffvww, and I'm getting extremely good results. I think we will all be using QuEnc more often ;) -kwag |
@kwag
I agree with you, QuEnc is very good. I would like though to have all the libavcodec options out to play with them. :twisted: I hope it will be in 1.0 release. I know that QuEnc has a very good quality right now but I'm targeted on small resolution (352x288) and any artifact is more annoying than with full resolution (I have double size blocks on TV screen). So thats why I am very picky and since the speed of ffvfw is acceptable at 352x288 (25-30 fps) and VBV issue is ignored by my player, you know what I choose for the moment. I am sure that QuEnc could do a better job with the right settings but we still have not access to them. marcellus |
As I posted earlier; my encode of Shrek looks amazing! Even though I encoded it in MPEG-2 and SVCD resolution (480x480). Have anyone tried QuEnc with MPEG-1 output? Results :?:

Yes. And another thing that's great about being able to encode good looking KSVCD's (MPEG-2) is that they're playable almost everywhere - on almost everybody's stand alone DVD players :D Even at my parents' house... :wink:

From what I understand it's best to use a closed GOP?
The setting I used for Shrek (NTSC) were the following: Main window * MPEG-2 * Use VBR - Checked * High Quality - Checked * Use Trellis Quant - Checked (But have no clue what this is :roll: ) Advanced options * Force Closed GOP - Checked * Use KVCD "Notch" Matrix - Checked * GOP Size=18 * Max B-Frames=2 * 4:3 Aspect Ratio Then, in the main window, I simply pasted the average bitrate I got from CalcuMatic and clicked Encode. Ta-da! Please, inform me if I should use some other settings for my encodes. Question: Can we use the GOP from the TMPEnc templates with QuEnc (PAL=25, NTSC=30, Film=24)? @Kwag Very nice quality on your Red Planet clip :!: EDIT: If you use HybridFuPP to encode your movies - Take the average bitrate from CalcuMatic and multiply it by 1.05 :wink: |
Well, my test got a very wierd result. I asked to encode 480x480 at 976 kbps, and used trellis, 2 pass VBR, Notch, GOP 18.
The file came out at 725 kbps. I opened it with BitrateViewer, and The Q line was constant at 2.67. I have the same file encoded with CCE at "real" 976 kbps, but still could not do a side by side comparisson. I opened the encoded file and it looked good, but in 17" monitor most stuff do. :D |

BTW, what was your final file size on "Shrek", compared to the size wanted by CalcuMatic :?: -kwag |

Note: When I use Incredible's Slicer routine to predict I also have to multiply the wanted sample size by 1.05 to get the final encode right. EDIT: This is when I use HybridFuPP to encode the DVD's |
Wait a minute....
So the average bitrate is not the average bitrate that the movie will be encoded? :? :? :? |
