Cce settings for hi compressions.

andy

I was wondering if there were any suggestions for hi compression movies like “Lord of the rings’ and “Harry potter”? These are 2 ½ to 3 hour movies that hit 65 to 50 % with “movie only” is used?

I will be using 4 passes but I was wondering what setting I should use in “CCE settings” for VRB Bias and Qual Prec.

Thank you.

I know this has been talked about but it was a little general, I want to know the setting that would apply to above said movies.

try the stock settings first, you probably though do want to choose different matrixes for low(gt;3000) and very low compression(gt;2000) in advanced settings IF YOU HAVE THE PRO VERSION. For higher compression I personally bump up the vbr a bit more usually around 32.

As far as passes 3 should be plenty.

I also have benefitted on those long films by adding some avisynth filters, like undot(), deen(), or perhaps another denoiser like vaguedenoiser. They will save some bitrate and help w/ compression.

example of setting undot().deen() I think the syntax is ok

Thank you, This place just rocks!

@Jack:

Hm, IMO 4 passes are really not required. Use the integrated OPV encoding for CCE, kick in some nice compression enhancing filters (e.g. KISS as suggested above or the kDVD filtering) and you are done....

If I wanted to apply filters undot amp; deen to just the extras (that I'm reencoding at Half-D1 amp; steal space), do I have to use something like RB-Opt? Looks as if adding those to RB's filter editor would cause the filters to be applied to all the VTS's, right? Also, if I did add the line in RB-Opt, where should I put the line -- before, after, or somewhere in the middle of all hte other stuff:Code:5 - LoadPlugin(quot;C:\vid\DVD-RB-Pro\DGDecode.dllquot;)6 - mpeg2source(quot;H:\D2VAVS\V02.D2Vquot;)7 - BilinearResize(352,480)8 - trim(165,272)9 - BlankClip(last, length=15)
10 - ConvertToYUY2(interlaced=true)
11 - AudioDub(BlankClip())
Thanks!

[EDIT] Sorry, another ignorant question: do I have to initialize Undot and Deen libraries as well, as in line 5 above? So do I have to stick in something like: LoadPlugin(quot;c:\Deen.dllquot;). And do I need the Deen DLL or is the function bundled in DGDecode?

I guess probably after the resize but I'm not familiar with the combination of Half-D1 and other filters.

No if you put your filters in avisynth/plugins subfolder otherwise yes.

You need for both filters dll's as they aren't internal filters. The best place to look for is this one.

many thanks, rippraff!!

@JohnGalt
If you used Rebuilder's Installation pack you have Deen and Undot on Avisynth Plugins folder already

I have just started using the Undot Deen filters when processing movies. The last one I did, Cry Wolf NTCS, is 6.9gb,
after processing it comes in at 3.86, a fair undershoot. I guess my question is, does RB take into account the bits saved by the plugins, or are the saved bits lost and not used in the recompressed output? Settings are mostly default, except for Half D1 for the extras, which are 4:3 ratio. Have read that bits can be saved with these filters, just wondering where they go, especially in this case. The filters seem to get rid of some of the quot;Filmquot; effect as well, flat areas seem to show a little less noise.

Long time Pro user, and lovin' it!

huh. obivously I'm no expert, but I backed up quot;The Big Sleepquot; using those two filters after all the help that I received here. The disc contains both the 1944 pre-release version and the official 1946 release of the movie. Significant changes were made between the two cuts. I care most about the '46 final cut, however, so I used RB-Opt to KISS the '44 version and raise its compression rate somewhat. At any rate, the encode turned out beautifully, and properly-sized (4.34G).

I have been fooling around with different options to make the movie Heat (only the main movie and main/scene celect meus from disk one) look good when compressed to fit on a DVD5. At first I encoded my edited disk (DVD Remake) with HC in BEST quality, VBR Bias = 16 and I got what I considered terrible quality.
Next, I ran the same edited disk through QuEnc in High Quality mode, 2 pass VBR with scene detection and trellis quantization turned on. After a 12 hour encode I ended up with something I felt was a bit more palatable, but still pretty bad. I decided QuEnc might have a bit more room to improve.
I then opened the edited DVD in Remake again and cut every scene up at every point there was a jump in action or color complexity so that I had a ton of short blocks with much more consistent bitrates. I re-encoded that DVD with QuEnc with Extreme and Slow settings, Scene Detection on, but left Trellis off, as I read that it is not reccomended for high compression. I also toyed with the low bitrate and very low bitrate matix settings. The small blocks made matrix application extremely precise, and made a pretty big difference in the final quality.
After a 16 hour encode I now have a much nicer looking movie, but there are still a few scenes that I am not happy with.
I think some avs filters would have helped the quality and compressability a bit with the problems I'm having (blockiness in some darker scenes and a few scenes seem to just have a general haziness). Can anyone suggest some good filters to use, and do I have to add them into the DVD-RB project and do the full 16 hour re-encode or can I just apply them to the .m2v files corresponding to the scenes I feel need them and rebuild again?

Just a note.  There aren't any bits saved by using filter plug-ins... the encode is applied against the filtered source at the assigned bitrates.  Filters can sometimes give you better results within the bitrate applied -- but the bitrate doesn't change.

The one exception might be if you are using OPV... because there Q is used as opposed to bitrate.  In that case, yes, they would be taken into account.

I was just wondering about those filters that Jamos said to try. Would this filters be a bad thing for regular DVDs i.e. 70% to 90% compression and I saw that there’s a place to add a check under mode quot;check to force reencode for filtersquot; is this to be checked for  the undot  and .deen to work?

All filters should be used judiciously.   A filter has a specific purpose, such as removing dots or smoothing...  but they all distort the source -- if you have a good source your really don't want to distort it.

So is it worth setting the OPV options and leaving it on to try and squeeze that bit more out of the bitrate, especially as you say that using filters won't actually effect the bitrate unless OPV is turned on

OPV is one pass encoding.  The only reason I mentioned it is because it encodes using consistent quality while multipass encodes using consistent bitrate.   So it is more affected by filters.  That shoudn't imply you should (or should not) use it when you use filters, though.

Filters modify the source in some way.  The modified source is sent to the encoder along with a bitrate to use.  So the encoder is going to output at the rate it's told regardless of whether the filters are there.   Sometimes on sources that have a problem of some kind -- like when the film is exceptionally grainy or dusty from being old -- filters can be used to make it look better.   If a disc is already in pristine condition, however, adding a filter won't accomplish anything (at least anything good) and will slow down your encoding for no reason.
