TMPGEnc setting + Prediction Questions (5 of them)
 

:?: hi fellas. #disclaimer# Before I posted this I did look for an answer to my question but didn't find any.... (i think it's too basic that's why)

Method:I'm using Red-M's guide
1)As I load my source in MovieStacker, under "streams and authoring" it shows that the fps is 29.97. I then follow instructions and go to TMPGEnc. I open the avs, and load the target template. Now, under "video" in settings, the frame rate is 23.976, do I change that to 29.97 because my source was?

2) Same area, go to "advance" tab, and it mentions details of my source video. How do I know if my source was "interlace" or "progressive"? How about aspect ratio? (since Moviestacker auto ticked the anamorphic box when I loaded my video source-d2v initially, does that mean it's 16:9?)

3)In the CQ setting, TMPGEnc opens with 2500/max 300/min kbits/sec. On the www.kvcd.net/e107/ "what is KVCD" it mentions "from 64Kbps to 3,000Kbps" Do I change the max and min bitrate to this?

4) If my input for the source video is incorrect, will it screw up the outcome?

5) Prediction: for the magic number the format is #totalframes / 100 / framerate. Do I use the 29.97 that Moviestacker said, or the 23.976 that TMPGEnc is going to encode with?

Thank you

aspect ratio
 

Part of question (2) about aspect ratio, I found that. It was in the statistics window when you use DVD2AVI. I also realized that the frame type goes ballistic during preview. I think it's going between "interlaced" and "progressive" because I get both frame-types depending on when I press ESC. Sooo, :? I don't know. Is it progressive or interlaced....a mystery. I still can't find answers for the rest. 8O

Answers for Queston (4) and (5)
 

:cry: NOW I realize that (after reading more forum posts) (4) is critical. I mean, you can make any movie alright, but maximum quality seems to be achieved by minor tweeks in the settings here and there. :D As for Question (5), with CQmatic and Calcumatic, OMG, takes the fun right out of filesize prediction. The combo pack of the two is super-awesome. Whoever wrote that is a genius.

Anywho, I researched on DVD sites for a definition of "interlaced" and "progressive." :evil: I got more confused. I know that if it is one or the other, there are respective filters I need to apply but I can't right now because I don't know how to ultimately determine it. So, from my original post of 5 questions, I have 3 left!! (please correct me if my self-determined answers are incorrect)

Try reading this (about interlacing):

I hope it helps

And that's the trap of some DVD sources.
Its shown as 29,97 but really its not interlaced or telecined .. its still at 23,97 with a pulldownFlag set.

Here I explained how to reencode a progressive DVD source with TMPEGEnc and why we don't do a "inverseTelecine" or even a conversion to real 29,97

Most of the Hollywood movieproductions which are based on film are progressive and "real" encoded at 23,97 FPS!
To author a DVD they add a PulldownFlag so the 23,97 FPS stream is shown on the PC as a 29,97FPS. By playing this PulldownFlagged Stream in a stand-alone-DVD-player the player recognizes the PulldownFlag-information and does an internal pulldown, so the 23,97FPS stream will be pulldowned internal to be viewable on your Tv as an interlaced 29,97 FPS analog NTSC VIDEO Signal. Cause TVs cannot handle progressive NTSC FILM signals.

And that's also shown as standard at DVDrHelp.com:
Shure a pulldownflag information can only be added to a MPEG2 Stream and we know that MPEG1 gives us better compression.
But a 23,97 pulldownflagged MPEG2 stream will give you defenitely a better CQ Value than a 29,97 MPEG1 (its explained in the Link above).


I'm still woking on a transaltion of my guide in english. When it will be ready, I'll post the link including the complete progress.
