Growltiger Posted April 18, 2015 Share Posted April 18, 2015 (edited) Please will you allow a general question about the total time to make a Blu-ray disk, assuming the starting point is a .ts video file about 2 hours long and the end point is a single layer Blu-ray BD-R disk. The ImgBurn program with my external LG BE14NU40 USB3 drive takes about 21 minutes to burn the disk (at 4x speed) and a bit more time to verify it. That seems very reasonable. I have a program called Nero Video from their 2015 package and it is a very simple little progam that allows one to make a menu and add the video file. It takes 4 hours and 40 minutes to build the files that one gives to ImgBurn. It all works, but it seems very slow? In the past I used Premiere Pro to make DVDs and I remember that was slow too. My computer is a few years old but it is fast - a Core i7 PC with 12GB RAM running Windows 8.1 64 bit. I can see all the cores are running at about 65% busy while building the files, and about 8GB of memory is in use. The disk is hardly being used. So I suppose that even more CPU power or a better program would help? My question is simply this - does everyone have to suffer this extreme slowness, or am I missing something obvious? Thanks.

dbminter Posted April 19, 2015 Share Posted April 19, 2015 It depends on a few things. In terms of time, are you saying it's taking 4 hours to burn the disc or 4 hours to create the folder containing the Blu-Ray playable contents? If you're just talking about burning time, 2 or 4 hours is definitely longer than it should be. My internal Pioneer Blu-Ray burner writes a single layer BD-RE in about 47 minutes writing every single sector. A BD-R is about 15 minutes. Plus, are these 2 programs writing the contents to Blu-Ray at the same time they are creating them? If that's the case, I can see it taking significantly longer. I've never created any pure Blu-Ray contents for burning, so I can't say how long it should take to create the folder contents on an HDD, let alone to a BD.

Growltiger Posted April 19, 2015 Author Share Posted April 19, 2015 The big amount of time is running the program to make the files. That takes almost 5 hours. It does "transcoding". Once all the files are ready, it takes only 20 minutes to burn (at 4x speed) and another 10 minutes to verify the disk. Link to comment Share on other sites More sharing options...
dbminter Posted April 19, 2015 Share Posted April 19, 2015 The transcoding phase may not actually be that long in terms of what I can compare it to. I can compare it to transcoding DVD with ConvertXToDVD. It takes about 30 or 40 minutes to create an full DVD of contents with that application. That's about 5 GB. So, 30 minutes for 5 GB would translate to about 150 minutes for 25 GB. That's 2 and a half hours. Of course, I've not idea how fast or slow this transcoding application is you're using for Blu-Ray. Or if there's an option for 2 pass encoding like in ConvertXToDVD. As was said before, your best bet is to find a support forum for this application you're using and ask if 5 hours is exceptionally long for transcoding 25 GB.

Growltiger Posted April 19, 2015 Author Share Posted April 19, 2015 Interesting. Yes, I chose 2 pass encoding, and the highest quality. So that could explain a lot. I'll explore this in more detail in that videohelp forum. But thanks for your comments. Link to comment Share on other sites More sharing options...
Chappy Posted July 6, 2015 Share Posted July 6, 2015 Hi 4 hours is not at all slow for encoding BR files, slow machines can take up to 36 hours or more! I have an i5 2600K that I clock @ 4.5ghz when converting/encoding BR files and it can take anywhere from 3 to 5 hours with 2 pass encoding. I'm testing hardware encoding using CUDA on my GPU cores (H.264) but I don't expect it to be much faster, if at all, than 8 cores @ 4.5ghz software encodes.
