How to put 1080i source onto Blu-ray MKV??
 

I have 1080i source as huffyuv avi, its 30gb at 25 mins.

I want to put it onto Blu-ray disc. Well the intention is to put a number of these videos onto one disc.

I have imported it into avidemux 2.7.

What next?

I have selected auto>720p which chooses mpeg4avc x264 codec. I think I read here on forum that 720p was Blu-ray compatible?

Should I avoid auto mode? If so what are the optimal settings?

When I go to save video, it wants to save it as mkv.

Is this the right video container for a Blu-ray disc or do I need another piece of software to convert it to say mp4?

Help! :depressed:

Mkv is a container, not a codec. mkv ciontainers cannot be used for BluRay. It appears you are trying to burn a BluRay optical disc as a data disk, not as authored "BluRay". Good luck finding a player.

720p is always progressive, never interlaced. So your 1080i will have to be dienterlaced to double frame rate for 720p (the frame rate will double and the number of frames will double). So if your 1080i begins as 29.97 fps NTSC, double-rate deinterlacing will make it 59.94 fps. If your 1080i is 25fps PAL, double rate will make it 50 fps PAL. The only other 720p format allowed is progressive video at film speeds (23.976 or 24fps). In any case AviDemux is expected to do a half-assed job of deinterlacing and a so-so job of re-encoding your original.

If you are thinking of making 720p at same-rate deinterlacing, it means discarding half your deinterlaced frames and destroying 50% of your original temporal resolution, resulting in stutter or judder during motion. 720p at 29.97 or 25 fps is not valid for official 720p BluRay. Further, if your originalm 1080i is actually movie-based video (telecined), deinterlacing will bork it.

What's wrong with 1080i? That's an official BluRay spec. Don't you have a player that's smart enough to play standard BluRay HD?

No, I didn't say I wanted to make a data disk. I said, I want to get the video onto a Blu-ray disc for playing on a Blu-ray player which would mean authored.

The problem as I see it, is that the 25min file is a 30gb avi with huffyuv codec. A blank disc is 25gb, doesn't fit without re-encoding which goes back to my question of which software and what settings.

From the weblink, the file should be AVC/H.265 - MPEG-4 AVC?

You also stated that you want "720p", which means deinterlacing and resizing. What's wrong with the original 1080i ? You'll save very little disc space, if at all, by re-processing for 720p mainly because going to 720p involves doubling the number of frames.

1920x1080 interlaced @29.97 or 25fps is BluRay compliant. As huffyuv it must be encoded to an m2ts container for BluRay, then it must be authored for BluRay disc. AFAIK, Avidemux won't output BluRay compliant mt2s files.

If you want 720p, 1280x720 non-interlaced at 59.94 or 50fps would be BluRay compliant for encoding and authoring. If you start with 1080i, you must deinterlace for double frame rate video and resize 1920x1080 to 1280x720, then encode for m2ts containers. After re-encoding you must then author for BluRay with an authoring program.

If your 1080i is a film-based Hollywood movie or TV show, it isn't true interlace, it's telecined. If you want 720p from telecined 1080i video, you must use inverse telecine filters to remove periodic duplicate pulldown frames, then resize 1920x1080 to 1280x720 and proceed from there, as above.

One good program that can do this, as well as burn to BluRay disc, is TMPGenc Authoring Works (but if it's telecined and you want 720p you'll have to inverse telecine and make it progressive first). If you want to use freeware, your choices and features are far more limited and you'll have to learn more about what you're doing. BluRay specs, whether for 1080i or 7820p, are very strict and specific as to container, frame rates, GOP size, etc. I'd suggest you stay with 1080i. A free program that can do this (except for burning) is MultiAVCHD, but it lacks many features that require pay software if you want them.

thought i had to have it as 720p to be compliant; thanks for the correction.
It is a tv show which i wanted to archive, so as you say wont be true interlace. I am happy to keep it at 1080i, avidemux just confused me lol.

I tried avidemux to re-encode to 720p mkv and it reduced the file from 32gb to approx 800mb. I will try multiavchd. thanks

This is somebody I've known for 15+ years, and consider to be a friend. We lost contact for a number of years there, and I'm thrilled to see him back in the video hobby scene. Be nice. :wink2:

The encoding is probably fine, though I shy away from "auto" anything. At best, I'll do CRF, which is an auto bitrate mode based on quality perception.

The encoding container doesn't really matter (raw, MP4, MKV, even AVI), and then authoring software will extract it into the M2TS containers used on the BD. TMPGEnc Author Works, for example, should not reencode compliant encodes, merely re-containerize the video streams.

You should obviously obey BD specs, but authoring programs may further deny (or allow) what can be done. Be sure to read the input/output specs on the authorware documentation. With DVD, it was far more straightforward than HD formats.

Huffyuv is killer on HD sources. It's why lossy (though almost lossless in quality) ProRes422 and DNxHD were made. I used both quite a bit in my studio days. I hated the Avid (DNxHD), preferred Apple (ProRes422). Only in specific cases did I use Huffyuv. When it came to HD work, I actually mostly used Mac editing/encoding (non-capture) workflows.

I've never really made many BD (though probably more than most people have, or ever will). But still. I went straight from DVD to streaming media (or non-disc archivals). So, for me, your conversations here are good to jog my memory, or even learn new stuff. I know we have a quite a few members here that do HD regularly, and I often ask deeseven questions, since we both exist in the same hobby community.

its all good. Just an old dog trying to learn new tricks.

dvd workflow seemed easier, tmpeng2.5, womble and dvdw2.

I think i might have mainconcept or valley procoder somewhere.
