It typically is 23.976fps -- but 24fps is also a legal blu-ray framerate. Here is info from "The Authoritative Blu-Ray FAQ":

PS3 Skipping

Hi Jdobbs,

I've been using your BD Rebuilder for a few months now. My BD player is a PS3 fat 80gb.

My typical archive process is to use use your product to extract MOVIE ONLY and size it to BD25. I use highest quality, 2-pass, and extract only one ENG subtitle and one ENG language track. I do NOT convert any of the audio (I keep the HD track intact).

With 2012 and now Avatar, I have been experiencing skipping. There may be other titles, but I don't watch my backups often... 2012 and Avatar happen to be the two I've watched recently using my archive copy. I thought this was related to my PS3, possibly overheating, but, in researching the various blogs and threads, it appears that it may be related to what BD Rebuilder is doing. If I play back a complete, uncompressed copy of the movie (using a 50gb BD-R), I do not get skipping issues.

The skipping generally occurs significantly into the movie (with Avatar, it was around the 1:39 mark, with 2012, I can't recall, but it was about 2/3rds through the movie). The symptom is skipping... as though the disc were dirty or scratched. It will randomly jump to other portions of the movie, and sometimes restart play from the beginning. Again, playback of an uncompressed copy on 50GB BDR plays fine..

At the moment, I am trying the following alternative: Use CLOWNBD to extract movie only, use RIPBOT264 to compress to 23gb and then use TSMUXER to remux the DTS Master back in (ripbot264 converts audio to linear pcm which I don't like because of the size). As I am still demuxing/muxing at this very moment (about 4 hours to go), I cannot tell you if the problem is replicated... my suspicion is that all will be well.

I report this to you only because I saw in a thread that back in 2008/2009 you identified and corrected a PS3 skipping issue... I am wondering if this "bug" was reintroduced.

I unfortunately do not have a BDRebuilder log for you (I've deleted the directory)... I can get one for you by going through the process again, but would only do it if you need it (as it takes 7-8 hours to run).

Hope this is enough for you to start with. Let me know if you need more.

Thanks.

-Kevin.

The symptom you are describing sounds more like a media problem than anything related to the rebuild. It would be very difficult for BD-RB to create a "skip". But I'll take a look.

The CRF is very high. That's the problem with CRF prediction. Sometimes the sample just isn't representative of the whole. It seems a little odd too, to hit the CRF in only the second iteration when there is that much difference (24.59 -> 37.29).

It must be a really short clip, only 24 Frames made even shorter by the extremely fast rate ( Rate/Length: 59,940fps, 24 frames ) Anyway why reencode such a short clip?

Hi jdobbs
First of all thanks for such a great program, I canīt really tell the difference between the original and the copy.
I recently did Avatar leaving all the audios at the highest quality and with two passes.
Then I burned it with Imgburn at 4x, when I play it on the pc with powerdvd works fine, but when I try to play it on the ps3 on a 50' Plasma sometimes I get some strange horizontal like transparent lines on the top of the screen, the lines are 6 cm height and cover all the screen horizontaly, the lines do not appear always on the same time, because i rewind and play the same part again and the lines disappear, but then again appear at any time of the movie.
When I play the original movie, I donīt have this problem.
Thanks for your help

no, the first pass runs much faster and the whole encode should be about the same amount of time. Under Settings, Encoder Settings, uncheck the One Pass options and it will run at two pass.

honestly, i have never done a One Pass encode. Basically the difference is that if you do a first pass encode, it averages out your bitrate for every frame so you may be applying too much bitrate in some scenes and not enough in others. When you do a two-pass, the first pass basically analyzes the frames and determines what bitrate should be used for each scene, although the average bitrate remains the same throughout the whole movie. I believe the two-pass method is the best, but then again, as I said, I don't do one pass encodes just because i have always done multi pass encodes with tv shows using vdub and dvds using cce. Hope this helps.

I have an update for you. This is a really bizarre issue, and I think part of it is related to a faulty PS3, but I do think that BDR is playing a role. Here are my latest findings/tests:

I have three PS3's. A "newer" 160gb (two laser) (call it unit A), and an older 60 and 40gb unit (single lasers) (call them Unit B and C).

I ripped Avatar with Anydvd, and then used your latest BDR to resize it to a BD25, using highest quality, 2-pass, and extracting only one english audio and subtitle track.

This BD25 copy plays up to about the 1:41 mark and then starts skipping on my Unit A. Just an FYI, a rip of 2012 did the same thing. At first, I thought it was faulty media, a scratch or finger print. I burned another copy to a BD-RW, and it too did the same skipping. Strange thing is, it doesn't always occur at exactly the same timespot, but generally 1/2-2/3rds the way into the video.

Then, as I described in my earlier post, I decided to rip the movie with ClownBD, and compress it using RipBot264. After doing this, and burning it to a BD25, I played it in Unit A, and guess what... it worked. I then played the BDR copy, and again, after about 1 hour, 41min, it started skipping again (on both the BD25 and BD-RW).

So, I then played the "suspect" discs in Unit B and C, and they played perfectly! So, I suspect that my Unit A is a faulty and am sending it in to Sony for repair.

However, as I stated earlier, I am suspecting that SOMETHING is resulting from BD Rebuilder as well... because why would the ClownBD/RipBot264 routine result in a disc that DOES play with no skipping?

So I don't have an answer, and I *do* think it is related to my PS3, but what difference is there between the BDR and ClownBD/RipBot burns that makes the latter work, and BDR not? For what it's worth, I threw the 00000.m2ts files from BDR and Clown into TSMUXER to see what the video track was like, and both are identical (they both use profile 4.1, etc).

Go figure.

I hope this helps.

-Kevin.

Ipad conversion Windows 7

I had to use mp4box version 4.6,dev. The supplied version was crashing in Windows 7 32bit pro. I know this sounds like a feature request, but can adding the ac3 audio track for appletv compliance become a possibility?


Great app.

Well, it will all depend upon your processor speed, but I would say, around average, it should take about 40 - 45% of your total time, maybe even a little less. So in my case, a 1 hr 45 min movie takes about 20 hrs, I would say it is split between 8 and 12 hrs.

WOW....20 hours to make a back-up seems long to me....it has never taken more than 4 to 5 hours from start to finish for any back up I have made including the 3 hour Lord of the Rings movies. I use the normal priority high speed BD-25 encode settings, and everything is done in one pass. I use Verbatim BD-25 media, have never had one to skip or glitch in any way, and I can tell absolutely no difference in the original and the back ups in either picture or sound quality, and that is with an 82 inch TV and a 7.1 surround sound system. I honestly do not see how the two pass high quality settings would make my back ups any better. If those options are needed to make a high quality DVD-5 or DVD-9 I will gladly trade 15 extra hours for the $2.00 difference in price per disc.

Seems long to me too. My BD-25 backups take about 3-4 hours and BD-5 (High Quality) is usually 10 hours or so. I'm using a low-end, older quad processor (Phenom 9500). I've heard that newer processors (like and i7) can do complete High Quality backups to BD-25 in 4 hours or less.
