Multiavchd or Imgburn problem burning AVCHD on DVD

[jbitakis]

I have been successfully Converting my 1920x1080p 60p m2ts videos to 1280x720p 60p Mp4 using Freemake Video Converter and then Authoring those videos using Multiavchd to blu-ray and then burning them with perfect success to Imgburn on a blu-ray.
I have about 90 DL DVD 8.4gb disks that I want to store some more of my 1080P 60P home videos on. So using Freemake again I converted the videos to 720p 60p Mp4 videos from M2ts files; used Multiavchd to author to AVCHD (strict) and just AVCHD, and imgburn to burn and I am getting errors when I burn I/O errors.
Is it the Authoring to AVCHD to DVD that is the problem?

how would "BURN" i/o errors have anything to do with authoring??? bad discs or burner. if it's a dl blank there was only one that was ever any good and it was verbatim. but these days a blu-ray disc costs the same as a dvd-dl so why wouldn't you just burn blu-ray?

Here https://forum.videohelp.com/threads/351325-This-conversion-authoring-burning-works-for-...32#post2203432 you mention 26Mbit bitrate, I wouldn't put this on DVD. It has its limits, it is not BD. AVCHD DVD is a bad choice anyway.

aedipuss, I have these DL DVD already. I'd like to use them. So it's the bitrate and its compatability with the AVCHD DVD? Is there a limit on the resolution for AVCHD DVD? Maybe I need to down convert it to dvd quality? Maybe that's the only way it will work? But going from 1080P 60P to DVD quality is a huge downgrade. What about HD DVD on multiavchd?

You can't use blu-ray bitrates on DVD media. The datatransfer rates are different for BD and DVD media. You run into buffer underruns. It has to be encoded with specific settings for DVD media . To be compatible with most players that can playback AVCHD on DVD media this means <24Mb/s , but some older players are limited to <15Mb/s .

What is that specific dvd setting? Or is it mainly the high bitrate that is the problem?

Yes it's bitrate peaks that empty the buffer

Besides all the other blu-ray compatiblity settings, the buffer and maxrate have to be <15000kb/s to be safe . But many players can play out of spec streams

--vbv-maxrate 15000 --vbv-bufsize 15000

BTW, that's in addition to possibly bad media, bad burner, etc... ie. the things the others have mentioned above

Technically you shouldn't put anything in a container before authoring. Converting a video and putting it in MP4 as container as you're doing will strip the sequence headers. This can cause problems with pro authoring tools, but many consumer authoring tools will "let it slide." For "best practices" you should be using elementary video & audio . But usually those types errors are at the authoring stage, not the burning stage .

If you have a log file it might provide more clues and help narrow down the problem

How do I use elementary video and audio? My burner works great. My media is ok too.

raw avc and elementary audio - Do you remember back in DVD days, you used .m2v and .ac3 ? (or at least you should have). They are separate audio & video streams without a container . When you authored it, it gets muxed into a VOB. For blu-ray you should be using .264 and elementary audio as well .

But that probably isn't your problem, consumer software and freeware "don't care" about these things. It's only very strict pro authoring tools that will complain
