Dear MB1,
I have once read somewhere - may be cdrsoft.cc forum - that you have made huge tests for Mainconcept 1.3.1.
As I have this product, I would like to use it to encode from DV PAL interlaced source to DVD compliant mpeg2 files.
Can you detail your results for maximum quality?
BTW, speed is really very fast, as it gets 1.5 times the length of the movie to encode - i.e. 90' encoding time for 60' movie.
I actually can get 3.5 with Tmpgenc CQ or CBR or 4.5 using 2-pass, and 8 with Procoder Master.
When using CCE, I have 0.5 - i.e. 30' for 60' using CBR.
But my extreme need is quality, as DV source is quite hard to encode. I have no bitrate problems - max length is 60'.
Thank you in advance.

Hello Paolo !
Have a look in the Link-Collection = Linksammlung
(A Link is in my Siganture)
There You will find at least two Links.
Matrizen for TMPGENc (Matices for Tsunami Encoder)
Szenario miniDV *****
(Both articles are also to be found in our Manual/Tips and Tricks Section
http://www.dvd-svcd-forum.de/phorum....SF;f=18
Hopefully this will help you , if not please ask again.

Hi Paolo,
you should not use an unchanged default dvd profile to encode your source material. Its main goal is speed but not quality.
I have posted already some tests and its logfiles:
http://www.dvd-svcd-forum.de/phorum....;t=1578
and also some older examples (with v1.2):
http://www.dvd-svcd-forum.de/phorum....;t=1593
Today I would recommend the following settings for dv material for best quality but needs also a lot more time to encode (little more than double compared to default settings):
Changes to dvd default profile:
- search 11/28
- line filtering
- GOP 15/3/0 for PAL
- noise sensitivity 7
- use user quant. matrices (but don't change the values !)
- Intra DC 0
- Pad frame percentage 10
- Rate control, reaction parameter depends on your source length.
For all material longer than 13 minutes use 9999 (default 0 means 1000).
Bitrate settings: min 3.000, max 9.000, calculate avg (but should be 6.000 and higher) for your needs.
If you are an experienced avisynth user use avisynth before to letterbox your source material with 16 pixels around (tv overscan which saves bitrate). Script for avisynth 2.07:
AviSource("c:/your_dv.avi")
Letterbox(16,16,16,16)
If you would like to use avisynth before (recommended) then change your import modules priority within mc-mpeg to "avi import" as the first one.
This lets you open avs-scripts but no longer dv material directly.
For dv material rechange to directshow ...
I've made a tutorial for that scenario (dv to dvd) but didn't release it until now. Will do that the next days ...
@bergH
If asked for mainconcept encoder settings why do you answer with tmpeg recommendations  _________________ Grüße

Happy new year, MB1, and thank you for your reply, detailed as usual.
Just a little more explanation about one point: when you say that rate control and reaction parameter depend on my source length, and that for length over 13' you suggest use 9999, do you mean it for both - i.e. rate control AND reaction parameter?
And again, why do you use intradc 0 - which should correspond to 8bit - and not 10bit ?
Thank you in advance

Hello again !
Sorry for passing the wrong links, I must have overlooked Mainconcept. Perhasp I should wear my glasses.
Happy New Year !

Paolo, you cannot change "Rate control" itself in the settings.
It is mandatory to change a subsetting.
Here I only change the "reaction parameter".
I wrote "Rate control, reaction parameter" for you to easily find the setting
Intra DC precision:
Normally for dvd bitrates the value should be set to 10bit for highest precision.
But for some encoders it is not needed as it is a "waste" of bitrate (which brings no visible quality increase on tv sets).
I use (depending on my personal testings) for dvd settings
- 10bit with Tmpeg
- 9bit with CCE and Procoder
- 8bit with MC Mpeg
Maybe you would like to read about the "bitrate waste" on this german site.
Aims mainly on svcd (from dvd source) but in my point of view there is an analogy for dv to dvd (as there bitrate and space is also "limited" in a dv point of view).
@ Paolo, bergH
Happy new year for you two, too  _________________ Grüße
