BD RB mp4 conversion

[eelrey]

When an mp4 file is converted using BD RB to blue ray and an iso. image is created and burnt to a dvd, the dvd blue ray player will not play the disk. Says disk is not compatible. I've tried several time to no avail. If I use another video converter and then use DVDFab to shrink it to a regular dvd disc, the Dvd player will recognize the disc and will play it. I don't know why it won't play. I like the speed that BD-RB converts the mp4 file to a blue ray, but don't know why after I create an iso image using imageburn, it isn't recognized by the player. Any suggestions

Are you simply importing it -- or are you actually reencoding it via BD-RB? Importing doesn't create a BD compatible disc that I call "pseudo-BD", very few MP4s are compatible as-is -- but BD-RB makes all the adjustments necessary to make it compatible when it reencodes and rebuilds.

I'm just importing an mp4 file and BD RB does it's thing. I thought when it went through all that processing, it was actually converting it to Blu Ray. What do I need to do after I import the mP4 file to convert it to an actual BR file?

after importing you still need to click the "backup" button. Only then does the pseudo-bd get converted into BD-compliant data

I'm just importing an mp4 file and BD RB does it's thing. I thought when it went through all that processing, it was actually converting it to Blu Ray. What do I need to do after I import the mP4 file to convert it to an actual BR file? All that is doing is checking the source and preparing it for processing (importing). On all the imports I've tested it only takes about 5 minutes. The majority of MP4 sources don't even have somethign as fundamental as a BD compatible frame size set properly (they like to remove borders, it seems) -- let alone have the source encoded with the basic required settings for GOP, buffering, rate, framerate etc. All those things require reencoding -- and I'd guess that even the largest multiprocessing multimillion dollar supercomputer on the planet would have a difficult time doing that in 5 minutes.

The exception might be importing DVDs. Since DVD standards were grandfathered into BD, you could actually burn directly from the import folder. Of course, if you don't resize to HD or do some type of filtering (both of which require reencoding), you're pretty much getting the exact same output that you would get from a DVD -- and since all current BD players will play a DVD... keeping it the same is kinda' redundant.
