DVD-RB and Encode, Transcode, QuEnc, ReJig, HC, CCE, Etc

[Rassilon]

Hi All,
I have read that ReJig is great on DVD-9's that are only slightly oversized. I have also read comments on which encoder works best and is the fastest on High bit rate, annimation, etc.

I'm using DVD-RB Pro and wanted to know the basic's on what to use and
When I should use HC, CCE, QuEnc, ReJig? :confused:

What's the difference between a Transcoder and an Encoder :confused: and when should I use them?

I recently used 100% compression and the resulting DVD came out slightly larger than the original. Is there realy any reason as to why I should reauthor(?) a DVD this way, or is it best to just do a DVD to DVD Copy with Nero?

I'm trying to show my friends DVD-Rebuilder, but it's hard when Shrink works so fast and I can't tell them why. The only thing I can think of is that shrink used a Transcoder?

:thanks:

ReJig is a great program, but there are others that have been updated more recently for DVD "shrinking". Such as DVD Shrink and Nero Recode 2.

Well, CCE is generally considered as one of the highest quality Mpeg-2 encoders. But, QuEnc (made by the same guy as ReJig) looks awesome also, especially since its freeware. So, usually your best bet quality wise is CCE. If you want a freeware high quality option, go with QuEnc. Some other people like HC, but i havent really tested it enough personally to recommend that.

If your not compressing at all, just a direct "DVD to DVD" copy, just use file mode in DVD Decrypter, and burn those in Nero using its DVD-Video files option.

Thanks for the links Feedback.

I read through these and it re-inforces my choice to go with DVD-RB Pro. (I prefer Quality over speed - I'm rebuilding a movie in the background as I type). What I'm still confused about is which settings, or rather which Mode do I use and when.

To me, DVD Shrink sounds like the equivalent to DVD-RB in ReJig mode? If I have understood the article correctly, a Transcoder like ReJig "leaves I frames alone, and applies its compression to B (and, to a much lesser extent, P) frames." but an encoder will recode the movie.

Thanks for your time and info.

I like to use HC the most. The default setting works fine, normal quality, DC9,etc.

However, I do use DC precision 10 in the Advanced options with HC with higher bitrates (above 3000) and the 64 bit floating point in the AVS options and normal quality.

I have been playing around with the BDVD matrix which I like but some standalones have issues with it. If you read both threads I posted you will know how to fix it, if need be.


HC is about the slowest of the bunch, QuEnc, CCE etc. but I don't have to pay for HC as opposed to CCE and time is not an issue for me. Besides, many others have indicated that the apparent quality difference is negligible between CCE and HC.

Also, HC is reputed to do very well with interlaced material. Still, it all boils down to personal preference.

i used HC,for most of my movies (and are interlaced.)
take 4-5 hours with HC against 10hours with Quenc.

i dont see anydifferecne between both and I did 50 backup so far.

avoid dvd shrink, the quality is not so god, the image looks "schrinked" when with HC, you will have some nice "tiny pixelisation"(come from the matrix).

use DVD shrink to make copies for your friends(they dont care about quality), if you do a backup for you, use HC or Quenc for your privat videotheque.

I agree johnhamler1, I found that HC was much quicker than QuEnc and both give excellent results.

Results from the Log File doing the same DVD.

QuEnc: PREPARE/ENCODE/REBUILD completed in 908 min.
HC : PREPARE/ENCODE/REBUILD completed in 533 min.

Why is Shrink so fast? Is it because it "transcodes" instead of ReCodes?

Would this be like using DVD-RB in ReJig Mode?

:confused:

Here's some very interesting information on transcoders (http://forums.afterdawn.com/thread_view.cfm/11/71507) that I ran across over in the afterdawn forum. Scroll down to zoef's post, it's the one with the best info.

When you speak of quality, well, it's a subjective thing. For many people, Shrink is so easy to use that it's just not worth it to them to mount a steeper learning curve. Some say Shrink is "great", so one approach might be to say that it depends on what your expectations are based on the entire roundtrip.

From the posted information I have found out that the resulting DVD's are subjective to the "Eye of the Beholder", so I will more than likely use HC mode over QuEnc as my eyes can't tell the difference and HC is a fair bit faster.

In relation to speed, I have friends that use shrink and they love it because of the speed, if I tell them that using RB in ReJig mode will yield similar results, would this be accurate? (I have never used Shrink).

When is the use of ReJig useful and Not?

DVD's are subjective to the "Eye of the Beholder",
As such you may want to try the application in this Thread Here. (http://forum.doom9.org/showthread.php?t=97114)A Matrix can make a difference in your perceived mpeg2.

It is to be used with DVD Rebuilder Pro.

Try it you'll like it.

Concerning the speed of QuEnc., if you have Trellis ticked in QuEnc. options it about doubles the encode time for just a little gain in quality.

Can't answer the Rejig question.

I'll give it a go - Downloading it right now.

I've left them all at the defaults.

This is a link to a Matrix zip folder Here. (http://forum.doom9.org/attachment.php?attachmentid=4081) It is full of different Matrices. However, some are not DVD compliant. The AVAMAT6 matrix has been recomended by some.

I personally use the CCE ultra low bitrate Matrix for extras on some DVD's when I choose steal space from extras at 33% mode in the DVD-RB Pro.
I do this using the HC encoder.

You may want to download the latest Rebuilder Matrix Editor v.2.0.4 Here. (http://dvd-rb.dvd2go.org/modules.php?name=Downloads&d_op=getit&lid=103)
The ability to pass the DC precision values of 8,9,10 are now included (located in the advance/expert options in Rebuilder Pro.) in addition to the one pass VBR option with the HC encoder.

what s the best , in term of quality, QUenc or HC.

I will get the alexander movie, 3 h pal, quenc or HC for a backup????

[feedback]

It is a subjective thing. Some people like QuEnc. some like HC.

Some people like chocolate, some people like vanilla.

I already indicated what I liked personally further up this thread.

I believe if you are using DVD-RB Pro. that the use of some of the different Matrices provided will have a profound effect on the quality of your Large 3 hour movie regardless of the encoder because the bitrate will be much lower.

Use the Rebuilder Matrix Editor and encode the same segment with a different
Matrix to see what looks best to you. I have heard some people get good results with the AVAMAT6 Matrix. Also,the Bach1 Matrix. Try them all if you have the time. On certain movies I like the BDVD Matrix.

P.S. The Rebuilder Matrix Editor at this time only works with the HC and CCE encoders.

[johnhamler1]

thanks,

well so far i stay with HC and qlb matrix.
