Blu-Ray Burn Begins With 5 Minutes Of "stuttered" Action

[novfilms]

hello all. i can't seem to create a blu-ray without having the first 5 minutes (almost exactly) stutter before becoming completely fluid through the rest of the burn. i'm using toast 12 with the HD plug-in, previously downloaded MKV files, and an Archgon External Blu-Ray Writer. i can find no options with either the software or the hardware that would give me a hint of something i haven't done quite right in terms of setting up the burn. it's almost as if the burn takes five minutes to get up to speed. the sound is in sync even though the stutter is occurring. i contacted corel and they suggested several forum topics but neither dealt with this specifically. as a newbie, maybe i'm missing something but it's beyond me at this point. i'd appreciate any suggestions. thanks, alan

What you are doing is beyond my knowledge or experience. You may get more assistance at the videohelp.com forum.

I have no experience with MKV videos so I don't know if the problem may be due to the source file. It may be necessary for you to use something else such as Handbrake to make a HD MPEG 2 video and then add that to Toast. Toast will multiplex rather than encode compliant MPEG 2 videos when authoring a Blu-ray disc.

 

A couple things to try with Toast is to do a test with a 5-10 minute clip. Go to Toast's custom encoder settings window and choose MPEG 2 as the encoding format. See how that looks (you can burn it to regular DVD media because it is short). If the problem is there go back to the settings and choose MPEG 4 as the encoding format. Maybe one will work where the other doesn't.

 

But my guess is you'll need to have something else make the HD MPEG 2 file from your source video.

i mainly use handbrake to create files that are for regular DVDs. on my copy of handbrake (FOR MAC) there are only two output sources mp4 and mkv. if i take an 11gb file for instance, i can only seem to create a mp4 file and my version of toast 12 doesn't seem to like mp4...when i use something like mp4 tools which creates an exact duplicate the same size as the mkv file.

 

generally, every group i belong to that shares blu-ray files puts them in mkv file containers. i've rarely ever seen a file over 4.7gb thats not an mkv file.

 

is there something i'm missing in handbrake?

 

by the way, i always use a minimum 8-12gb source file for every blu-ray burn

actually i have a program call macX dvd converter pro and it will convert mkv to various formats so i'll try the HD video mpeg 2 setting and see what it does. i'm doing the same movie again in toast and i'll try the next burn with the alternative file and see if it makes a difference. it will of course make the process that much longer as the mkv to mpeg2 conversion is 1 x 1and the toast enconding averages about 48 hours per encode

You shouldn't have to deal with Toast encoding times if the mpeg 2 file is seen as compliant to the Blu-ray specs by Toast. If Toast does say it is encoding instead of multiplexing then stop the process and go to Toast custom encoder settings window, choose MPEG 2 as the format and choose Never Re-encode. Hopefully this will all work out for you.

so tsantee, should i not use MKV files at all but instead convert any files i get to mpeg 2? the first one i tried converting turned an 11gb file into a 3gb file. should i want to keep the bigger file size. there has to be something in the type of file i use and how i convert them.

 

to be specific, i'll get a blu-ray movie as a torrent download, open it using VUZE, and it downloads as a MKV file. so, i just assumed thats what i should be using to re-burn with. but it seems i should always now convert them to mpeg2 from what you're saying. i guess i always thought burning blu-rays were different and needed a different file type to burn.

 

bottom line is that the file still should be in the 8-12gb range for best quality shouldn't it?

 

handbrake makes the files too small and if there's a blu-ray setting somewhere, i have no idea where it is and i've used handbrake forever

 

using the macX dvd converter pro, the first conversion turned the "a most wanted man" mkv file of 9gb into a 3 gb file so that can't be right can it?

 

i'm converting again now with all the settings on high to see if it makes a difference.

 

if you have a better way for me to do this (on mac) i'd be thrilled. i've gone through 8 blank verbatim blu-ray discs getting the exact same result each time regardless of the film (feature name or file size but always MKV)
