BD-5 copies are great

[datman]

I do remember jdobbs saying that for most movie-only backups BD5 is fine but I still did most of mine in BD-9.

He is right I started doing a few in BD-5 and everyone looks and souds great. There must be a point that a film is to long or to much data that BD-5 is not the best option.


One more thing I found out, you can burn and read these backups from most any computer (as long as it's up to snuff) and has a DVD drive. The only time you need a BD drive is for the rip.:D

The only time you need a BD drive is for the rip.:D I think DVD-5 is good up to about 2.5 hours in most cases. Of course a film with huge amounts of action might cut that back a little. If using two-pass "High Quality (Default)" mode I think the vast majority of movies look good on BD-5.

I have been using the highest setting with 2 passes

I do almost all of my backups to DVD-5 at 720p including 2 audio tracks ac3 448 kbps. Quality is normally very good given the fact that that the rate factor (or crf) is typically in the range of 18 ...22 for movies up to 2:30 hours.

Do you find that 448 audio is better leaving a little more room for video.

the only possible defect I have seen is during a fast moving scene the motion is choppy.

I have been doing all my backups on BD25 or BD9 until I decided to try a BD5 because of this thread. All I can say is "I am Amazed".

I did Spider Man 3 using default and 1 Pass,the 1 pass was by accident as I intended to use 2 pass but none the less it is simply amazing. I have viewed scenes from the original, my BD9 and this BD5. All 3 look just like "sisters" using a 50" Samsung 1080p and a Panasonic BD55 player.

Thanks JD, Dark S. and the rest. I now have a use for the 1000 blank TY 8x I have!! :thanks:

Yes, because I keep 2 audio tracks. Hence the saving is 2 fold, i.e about 300 MB which gives about 10% more bitrate to the movie on a DVD-5. At the end it's a matter of personal preference however.

I am not sure if or how the 'motion choppiness' is related to the bitrate. (?)

I'm not sure either. The original may also have the defect I haven't compared them it seem like it was a lttle smoother

I've been doing virtually all of my backups (movie only, single audio track @448kbs) to BD5 with the only exceptions being 2 hour plus movies with lots of action scenes. When confronted with those I move to a BD9. The results have overall been consistently good and visually artifact free.

I stick to a 2 hour rule for copying to a BD5. Its the timeframe we were talking about a year ago and since its worked so well, I've never deviated from it. I still do most of my copying to BD9 though. My brain has a problem accepting a 42GB Blu-Ray will fit onto a SL DVD and still look good.... even though it obviously does. :)

The 2 hour rule seems to make sense to me since I've been doing from the start (I'm cheap). I tend to ignore the physical size included on a disc because it doesn't tell the full story. Much of that size consists of foreign language tracks, large HD audio tracks, and extras and I keep neither. My rule of thumb is that 448kbs (I generally will keep a 640kbs track) is more than acceptable for a single audio track and any movie under 2 hours will mostly give about the same result.

I just use CRF encoding, but I've been amazed how small some of my basic, unfiltered 720p backups look! It's curious indeed when a ~2 hour, 720p encode at CRF18 comes out to be under 3 gigs and looks just as good as the 1080p source. Actually, scratch curious - it's awesome :D

When doing these encodes, I typically do 5.1ch audio using Nero LC-AAC Q=0.4. It usually comes out under 400kbps, and will be basically transparent to any kind of source.

I just started using BD-Rebuilder and have done my initial tests using movie only encodes to BD 9 using 2 pass encoding at the Highest quality setting. On a Q6600 @ 3 GHz, the Earth discs with 2:30 features are taking about 10 hours. I'm re-encoding to reduce the bit rate to where I can play the files over a wireless N network to media players (CinemaTube and WD TV Live) from a D-Link NAS and I'm very pleased with the results on the first couple I've tried.

Has anyone compared the results at the highest and default settings for 2+ hour movie only encodes? I'd be very interested in any personal opinions on quality and re-encode time comparisons. I hate to give up quality just to save time but given the huge number of options that that X.264 provides I recognize that the BD-Rebuilder quality settings are probably arbitrary albeit well chosen.

I've just become aware of the work being done on accelerating H.264 encoding using NVidia CUDA. Is there any hope that this type of capability might find its' way into RB-Rebuilder at some point? Buying a new graphics card is certainly more attractive than building a brand new I7 system just to get faster RB-Rebuilder encodes.

re: CUDA - there are tools that can use it, but they absolutely suck compared to x264. If you want that kind of speed, you'll get better results with x264 tune for extremely fast and low quality settings.

What preset are you using in BD-Rebuilder? The default x264 preset "medium" is an excellent balance. "Fast" or "Faster" don't loose too much, but going much faster than that will start murdering quality rather quickly!

~MiSfit"faster" turns off Psy-RD, which is a pretty big hit.

Is there an option to go down to 720 in BD-Rebuilder, or are you using another tool?

I may be thick, but I cannot get my head around how bumping a full blu ray movie down to a DVD-5 will look any good, but it must do as many on here are saying exactly that!

One other thing, I have a 46inch LCD, how will these DVD-5 720s look?

TIA

encode one you will be amazed. At the highest setting they are perfect. The only loss is the HD audio for most discs you will not notice the difference

Settings => Setup: Tick 'Resize 1080p to 720p'
For a DVD-5 I also recommend to tick 'Use 448 kbps for AC3 encoding'
Video quality is very good for my eyes even with the default 'High Quality' setting.

The Quality on a BD-5 is actually quite stunning, for a measely 4.7GB!
