Can I go from M2ts to M2ts & just decrease the resolution

[poisondeathray]

some blu-ray players actually deinterlace this on top (very bad)

not if the blu-ray player handles the spec like it's ment to be handled,..

But they should handle the spec properly - I should be more specific it's actually the HDTV that potentially does the deinterlacing

Nowhere in the blu-ray spec is 1080p29.97 present . It's not compliant or in the spec. Encoding and flagging as interlaced a "trick" or a workaround to allow 1080p29.97 authoring because to the blu-ray player it looks like 1080i59.94

The blu-ray player outputs a 59.94 Hz signal to the TV, it's the HDTV that potentially does the damage . Content aware HDTV's (these are ones that detect cadences like 3:2) and apply appropriate processing won't get fooled

added a new feature to Hybrid which allows to interlace the content so one can do 60 frames per second to 60 fields per second. (60p -> 30i) with it.
@jbitakis: if you want to try it send me a pm where you tell me on what os you use Hybrid and I will send you a link to a matching new Hybrid development version

man that was fast

You are a super developer extraordinare Selur! Too bad not all developers were so committed

I'll have to give hybrid a try out

[Selur]

remember the new feature is not added to the current public version,.. (just encountered a bug, that needs fixing,.. arghh,.. need to go to bed -> more development tomorrow evening)

If I had to make blu-ray from this I would choose 720p59.94

There is one more thing involved, how much of real resolution a camcorder actually has? Tested with some test image. Isn't it something like 700-800 pixels? Never had a chance to do something like that.

So real damage to downscale to 720 is minimal, is that true? As oppose to completely disrupt structure of video taking half of the fields away. Home video is not likely shot on tripod etc., there is constant movement involved.

The one you guys are using - I think it's the Panny Tm-700 or 900 or related model ? The resolution is actually pretty high measured on resolution charts , close to ~900 lines resolvable detail. You can find this data on various sites . That's actually huge for a consumer model . So going to 1280x720 will be some loss

You can do an downscale/upscale test and see the degradation in quality . I borrowed the tm-700 from a friend a few years ago did some tests and the findings support this

[jbitakis]

Personally, I would use a HTPC , forget about optical media. You can
play the full quality 1080p59.94 full spatial and temporal resolution . If I had
to make blu-ray from this I would choose 720p59.94

What is HTPC??
And it looks like we can all agree that if I need to place this 1080p 60fps video on blu-ray, that converting it to 720p 59.94fps is the way to go.
But I am still lost with all this avisynth coding thing. I still want to "try" and interlace to create ACTUAL interlaced CONTENT from my 1080p 60fps video. It sounds as if Selur says the blu-ray player should play MBAFF since it's interlaced encoded but Poisondeathray seems to not be so sure. So I really need a step-by-step instruction on how to, using avisynth, create actual interlaced 1080i 60i/29.37fps CONTENT, not just MBAFF.

acronym for Home Theatre Personal Computer. You have a computer in your living room. Don't worry - there are designs and cases that look "fancy" so your wife doesn't get too angry

But I am still lost with all this avisynth coding thing. I still want to "try" and interlace to create ACTUAL interlaced CONTENT from my 1080p 60fps video.

This was the option (4) I was talking about

Selur was kind enough to update his program to give option 4 - you should give it a try . He should have PM'ed you the link to the beta build

It sounds as if Selur says the blu-ray player should play MBAFF since it's interlaced encoded but Poisondeathray seems to not be so sure. So I really need a step-by-step instruction on how to, using avisynth, create actual interlaced 1080i 60i/29.37fps CONTENT, not just MBAFF.

Nope, MBAFF is perfectly fine for blu-ray. MBAFF is a method of encoding (PAFF being the other form of "interlaced" encoding), but something using "MBAFF" doesn't necessarily say anything about the content.

But there is a compatibility issue with authoring x264 streams encoded with MBAFF and 1 piece of specific software, DVD Architect . If you use anything else it's fine

I got Selur's PM, tried out his new Hybrid, but got an error message about FFmpeg which I sent to him. Stuck there. Can't wait to try out his new feature though about going from 60p>30i. So just so you know, I am using a Panasonic HDC-TM90 camcorder. Here is a link to the specs. http://www.camcorderinfo.com/content/Panasonic-HDC-TM90-Camcorder-Review/Specs-and-Ratings.htm
I do have the option to record in 60i, which would make placing it on blu-ray much easier (all I would need to do is author and burn), however, I have been reading that it's always best to record in the highest quality possible. What do you all think?

[poisondeathray]

Yes, it's a good idea to record in the highest quality possible for archival purposes. Any thing you do to it will make it worse (any re-encoding)

For example newer blu-ray players from sony can play 1080p59.94, and it's in the AVCHD2.0 specs . Hardware only gets better and better

You can do it conversion to interlaced with the avisynth script posted posted on page 1, there is a bit of a learning curve - if Selur gets it working in a GUI it would be easier for you

Unsurprisingly, we found that the 1080/60p format produced the sharpest results, with the TM90 able to resolve 800 lw/ph horizontally and vertically.

That' s still very good for a consumer camcorder

[Selur]

not sure if I mentioned it in the pm, the version I send you will use avisynth to do the progressive->interlaced conversion if the avisynth extension is installed.
so loading the progressive source, setting blu-ray compatibility (+ configuring your target bit rate or rate factor) and enabling 'Interlace' should do the trick. This is what poisondeathray mentions as option for.
this will create one field per frame and not like b lower the frame rate and than reencode the content as interlaced and thus keep more of the original temporal informations.

@jbitakis: just send you two pms explaining that the Hybrid.exe is just an update, you need either:
a. create a portable Hybrid folder with it
or
b. extract the Hybrid.exe into the Hybrid install folder
Hybrid stopped in the case you mentioned since the Hybrid.exe wasn't in a folder where the ffmpeg.exe was present.

Since it might also be interesting for poisondeathraay:

Here's how to create a real portable version of Hybrid:

• download 'Windows 32bit package' + 'Windows 64bit additions' if you are on a 64bit system
  these packages contain all the tools Hybrid needs.
  + if you want to use NeroAACEnc, you need to download it from http://www.nero.com/eng/downloads-ne...-aac-codec.php and extract the NeroAACEnc.exe into the Hybrid folder
  + if you want to use qaac (for aac encoding), you need to have Quicktime installed
  + if you want to use fhg (for aac encoding), you need to have Winamp installed or libsndfile-1.dll, enc_fhgaac.dll, libmp4v2.dll and nsutil.dll inside the Hybrid folder
• extract them to a folder e.g. named 'Hybrid' (1st 32bit than 64bit version)
• if you want the avisynth extension also download it and extract it into the same folder
• replace the Hybrid.exe in the folder with the one I gave you a link to (32bit or 64bit version)
• create an additional subfolder in the Hybrid folder named 'settings' (this is where Hybrid will save all it's settings)
• create a file named misc.ini inside the folder and put the following in it:
  

  [General]
  settingPath=".\\settings"

  (this will tell Hybrid to use the settings folder)

-> now you have a fully portable Hybrid version

Ps.: have to go now, buddy of mine is moving today and needs help carrying all his stuff, will check in with you later in the evening

So if my Panasonic TM90 is able to resolve 800 lw/ph horizontally and vertically, then going to 720p doesn't really downgrade that much, right? Because for the last month, I have been keeping my Camcorder settings on 1080i 60i/29.97fps instead of the highest 1080p 60p, and after copying the video files to my computer, I compared the 1080i 60i to the 1080p 60p and it is a noticeable difference to me (with of course the 1080p 60p being very superior). In fact, to my eye, the converted 720p 60p video is even better than the 1080i 60i/29fps video. Just my opinion. Thanks Selur for your great Hybrid software. I am still gonna try and do a conversion from 60p>30i just to see if I can do it. But most likely I will either buy a newer Sony blu-ray that is Full HD 1080p 60p compliant or convert to 720p 60p. Does anyone know of the models of Sony/Panasonic that are blu-ray full HD 1080p 60p compliant?

[Selur]

Thanks Selur for your great Hybrid software.

Happy you like.

Does anyone know of the models of Sony/Panasonic that are blu-ray full HD 1080p 60p compliant?

Sorry, no clue.
