hi man i dont know its right place to ask questions as a newbie but i have started MEGUI a week ago but i cldnt get my results as my source every thing works fine . can u just guide me what can be the best video profile to get the result like source ..

my system spec
CPU: AMD Turion 64x2 Mobile technology TL-60
RAM : 2 GB
Adapter Type GeForce 8400M G, NVIDIA compatible

MEGUI version 3.0.2005 (All updates installed)
Video Profile: x264:HQ-Slower
Audio Profile: Nero AAC: NDAAC-LC-64kbps

i m using this but result is not like source even its lil blury .. can u help me out what i m doing wrong . i calculate AR maually and use BitrAte 500 may be u have seen movies in 300MB basically i m try to rip a movie of 2GB that is HDRip.x264 in to 300MB .. if some one can help me . specially SHARKTOOTH. i have just waited really 5 days for this to post my question so i hope i will get somehelp..

i am transcoding with hardsubs and i noticed that in the 1st pass (x264) the ffdshow is started with subtitles forced to OFF...on the 2nd pass the subtitles are ON...i think this behavior is corupting the 1st pass quality (or not?)...as a quick fix i rightclick on the ffdshow icon and turn subtitles ON as soon as 1st pass starts...best regards

well, the bitrate is really low, also there is no best as per forum rules.
also you have an old version of megui and HQ-Slower doesnt exist anymore so you havent all the updates...

definatly, yes. go to your ffdshow configuration (from start menu->programs->etc) and enable the subs before encoding.

i have updated my MEGUI now its 0.3.0.2008 and 2ndly i know HQ-Slower is not available more but i have imported it. now i have tried new one
x264: DXVA-HD-HQ
and also some others . but i yet get my result blurry and abt bit rate if i increase it will increast its size also . so i want to make its size up to 300 if its 1.30 minutes movie .Basically i m trying to encode a movie that has already been encoded HDRip.x264 into more smaller size with more smaller resoultion but want to maintain its Aspect ratio and its Quality but i cldnt i can maintain its Aspect ratio but cnat maintain its Quality it becomes blurry

Source.. HDRip.x264
Resoultion.. 832*416 (Anamorph) ...
AR: 2.423

Ecoded:
Resolution 660*272
AR:2.426
i m using filters in avi synt is progressive and video pRofile is . x264XVA-HD-HQ
but what i get u can see, some pics after encoding




Code:

You want convert a 2GB (832*416) movie to a 300MB movie with AR=2.423 and same quality.

If you ecuate the quality factor Qf (bits per pixel) from two movies you have:

Qf = Bitrate1 / (fps1 x height1 x width1) = Bitrate2 / (fps2 x height2 x width2)

With fps1 = fps2 and height2 = AR x width2

Bitrate1 / (height1 x width1) = Bitrate2 / (AR x width2 x width2)

width2 = SQR ( (Bitrate2/Bitrate1) x (height1 x width1) / AR)

If Audio bitrate is reduced also, we can replace Bitrate2/Bitrate1 by Size2/Size1 (more or less)

width2 = SQR ( (300/2000) x (832 x 416) / 2.423) = 146
height2 = 146 x 2.423 = 354

Or maybe better 352 x 144
If you use more high resolution you have less quality

i have tried this resolution even its more worse than before . here is another movie that is encoded by other user. with resoultion of 660*272 it works fine and so smooth .




Code:
http://rapidshare.com/files/140306860/_400MB___HDRip__The.Matrix._1999_-Sample-Adz-Salman.mkv
i want this type of result but i cldnt get it . and the way u told i tried to do that but its more bad even and so small resolution even by using --sar it doesnt even hep..

Hey all,
I'm still working on getting my first encode to work. I'm working from an mkv container with a 1080p bluray movie in it created via eac3to.

Test encodes of various parts of the movie of up to 12k frames long have worked fine. However every time I try to encode the entire movie - The result won't play.
Megui finishes with no error messages after 14hrs of working away. The final file looks about right; in terms of size and properties. However when I try to open it in MPC or MPC_HC, it won't play? The smaller tests play fine, but with the final 11Gb version - MPC sits there saying 'opening' but nothing further happens.

Has anyone got any ideas?

'cheers
S.

Maybe the source (2GB) have already some artifacts.
Use always original sources when you make your backup copy.
Try with SD profiles, I can't understand for what you use HD for 660x272 at 434 Kb/s.

This backup have a video bitrate of 546 Kb/s (your movie 434), maybe from a better source, ...
Each movie is different.

it will be very useful if you extent the timer for shutdown to 60 secs and add a beep sound to it (with an on/off toggle in setting)...best regards

especially Rule 6. If you own the original then encode from that instead.

Thanks for the advice hubblec4, I'll try that tonight.
Interestingly, just before powering down last night, I tried the full length encode in WMP11, and it played! So I am starting to think it is a problem with the splitter or something similar.

@saza0500: re-encode from the original source, not the already encoded material and RISE the bitrate.
if you havent the original then you're violating one of the forum rules (no. 6)...

postprocessing options will alter the source in the decoding stage

^ He means if you have any filters enabled in ffdshow (when you right click the icon you will see many options), or other direct show filters in the decoding chain, they will pass through to your encode.

this is what i want to know . which filters will be good one for quality . encoding . or is there any help available for configuring FFDSHOw for geting best quality encoding

There is no "Best". Forum rules.

As a general rule, you should leave everything off, otherwise you get incompatibilities and compounding effects.

Do a search and experiment with settings. Test encode small representative samples so you don't waste time. What works well for 1 particular encode might not work for another movie...
