Hi all Im getting used too and playing around with DVDFAB backing up blu-rays. i want to use 25GB discs and if possible keep HDMASTER audio as i have a AV system. my question is, If i am compressing a 33GB main movie to a 25 GB disc with the intention of keeping the HD Audio. am i a) best compressing the film at 80% with the setting used in DVDFAB or b) compressing the file to say a 25GB MKV?? with the intention of keeping the best video bitrate?? also, i have a CUDA enabled graphics card, i dont know what this is. Should i be using this, or some other settings. and are there any tweaks in the settings people use to get the best results. thanks in advance. Damien

I can only relate my experience in compressing to 25g with and without the HD audio. The higher the compression rate, the lower the quality of my copy. Thus, if I can achieve a compression rate of only 20% or less with HD audio enabled, I go for it. If the compression rate with HD audio is around 40% or higher, I disable the HD audio, which lowers the compression rate. In my experience the higher the rate of compression, the lower the quality of the final copy. Thus I will trade audio for a lower compression rate. I hope this helps. Also, if my advise is incorrect, hopefully someone will chime in. --rjl2005

I missed you question about the CUDA. You have to experiment with those settings. I have had discs that I can copy with CUDA enabled and other discs for which I had to disable all hardware codecs and just use the software codecs. As far as I can tell, it is a trial-and-error process. Good luck!

I would never compramise the audio quality unless u don't have hd audio player.

You mentioned the option of creating a 25 gig MKV. I think personally the MKV solution is the way to go although I think you would find the resulting file would be more like 5 - 8 Gig. There is a profile you can use to retain the full HD audio with no compression (MKV H264 -audio copy). This uses the H264 codec to shrink the movie but no compression on the audio. The H264 codec is amazing and I think you would find the result pretty much identical in quality to the original. (I can't pick the difference) The down side is you loose your menu structure but this is offset by the fact that you can fit 3 -4 movies (more depending on size to each disc) provided your blu ray player is cabable of MKV playback and I assume from your question that it is. The cuda option relates to your video card. The software offsets some of the processing to your graphics card to share the load with your CPU. From dredging through the forums it appears to be a bit hit and miss regarding quality and is the first thing they seem to tell you to turn off when things go wrong. Perhaps you could try turning off Cuda and Lightning recode to start with and when you are happy with the result try experimenting with these settings and gauge the result. You will find a quicker process time but the quality may suffer.

Thanks for getting back people. i am tempted to go the MKV route and keep the hd audio. is there a way to set it to 25gb, because i tried one last night and it came in at 28gb?? Ive watched 8-12gb mkv before and found the quality to be good, but there is pix-elating in dark scenes due to the compression.. i am hoping if i set this to 25GB the compression raitio will be more effective then say the standard compression used in the DVDfab. i think in general though as long as its not compromised by more then 20% ill just stick with DVDfab settings and tweaks some settings?? dose this sound like a good idea?? are 25GB MKV with HD audio in general better then 25GB rips using DVDfabs alternative compression settings?? thanks

Please... I need an explanation of this MKV of which you speak!!! :) I would love to keep the HD audio as I too have a wonderful AV setup. How would I do this? However, I really don't want to spend a whole day compressing one disk. Thanks for any information.

ive tried mkv remuk and they dodnt work with my lg player playing off a hard drive. I dont car about the size aslong as i can keep the hd audio.

Thanks for any information.[/QUOTE] Check out PNG 1 Its BLUE RAY RIPPER > MORE > MKV.....then down the bottom drop down arrow on profile select >mkv h264 audiocopy (see PNG2) After that I pretty much go with the defaults although I should add that I have GPU acceleration turned off and also Lightning Recode also off. Ripping time is approx 1hr 20min on 64bit win 7 pro , I5 750 with 12 gig ram. Results are excellent. I copy movies to NAS and watch through networked WDTV Live media player.

I save to NAS and view via networked WDTV media player (no DTS master audio unfortunately but plays the core no problems) See attached

to bad about the master thats what i would like to keep.

BD25 and HD Audio best settings

generic.avi.Divx.audiocopy will give you a DivX avi with AC3 audio.

i want to keep the hd audio

GregiBoy

Not in that container you won't. Forget it...

Use MKV Remux to retain HD Audio.

cant wont play on my player

You should invest in an HD audio/video player that can play from blu-ray disc folders or ISOs.

hanibal

any recomendations?

GregiBoy

Dune, AC Ryan, Pivos, WDTV, Kaiboer, Measy & many many others. There is a specifc thread discussing this which may help.

hanibal

which one will play hd audio? wd dont

Garry E

Dune YES
AC Ryan no
WDTV no
Pivos Dolby hd yes DTSMA no (I think > just looked at a review today)
Don't know on the others

hanibal

pivos does do dts hd, grabbing one today.

Garry E

Happy days
