TMPGEnc: How to Use the Auto vbr Mode?
 

sory all im a n00b.

1st of all do i just leave the aspect ratio on 1:1VGA when making the m1v. also can anyone explain how to use the autoVBR mode? i heard it can help to conserve the size of the audio.

also under the MPEG Settings. under the first tab of Video in "Video stream setting" do i select the frame rate of my original avi? and if so (mine would be 25.000fps) will i get a chance to change it to 23.976fps when muxing?

and my original xy of my avi is 608x366. should i use the 352x240 kvcd temp? my movie runs for 98m34s

also my mp2 file i have created is still in i believe 25.000fps since my original avi had that frame rate. now is there going to be a conflict when i mux my m1v (assuming that i have to change to 23.976fps)

finally for the CQMatic i get the info:
Average Bitrate: 966.3kb/s
0.57*Average: 550.8kb/s

now where in TMPGEnc do i input that information. and for the CQ settings in TMPGEnc, what should i set as the video quality..100?

thx in advance
:)

Re: Some TMPGEnc Questions
 

As your source is an avi, yes you have to select a SOURCE A/R of 1:1. But the DESTINATION A/R must be set to 4:3 (and the arrangement method to "fullscreen - keep aspect ratio".

Forget what you had (or think you had) heart. This has nothing to do with audio and do not use it.

No. The fps there is the one of your target. BUT here your target fps is different from the source one and tmpgenc CAN'T do taht correctly.
You MUST use an avisynth script to perform this correctly.

For that length you can use 544*480. 352*240 is for a 2h30 movie.

All depend on how you change the fps with the avisynth script.
If you still want to change the fps with tmpgenc (using directly the avi as source) then you have to do the change also on the audio. So you must use besweet to encode the mp2 as it allows you to do fps change during the process.

In the same screen where you can change the CQ, put 550 in the MIN bitrate setting. Put 2200 in the MAX video.
966 must be given to CQMAtic. And that is CQMATIC that will find the correct CQ so you do not have anything to change in the default CQ under tmpgenc !

wow thx for all ur help!!

so for the CQ u are saying that the cq will automatically change the cq values before i open tmpgenc? where did u get that 2200 for MAX?

and what is this avisynth process and what do i need to perform it?

when i was in besweet. and i selected the dropdown for 25.000 --> 23.976 and clicked on WAV to MP2 it did nothing :? arg here's the command:


also what is the difference between mpg1 and mpg2. is it for kvcd and skvcd. and which one is better?

Hello to everyone ! Advancing in that question, if my source is MPEG-1 at 29,970 fps and I use the KVCD-CQ-352x240-_NTSCFilm_-PLUS.mcf template to TMPGEnc in order to reencoded it (I wanna to put subtitle in the one), generating a 23,976 fps (internally 29,970 fps pulleddown 3:2), I´ll have audio synchronism trouble ?

Cheers,

If the source is a true 29.970 then you must encode it in 29.970, not in 23.976 pulled down.
