How to encode 1080p60 H.264 to Blu-ray compatibile?

[BeatCrazy]

Hello,

I hope this is the correct forum for my question.

I recently acquired a Panasonic HDC-TM700 HD camcorder. This camcorder can capture at 1080p60 or 1080p24 via a 60i wrapper. I would like to shoot, and archive progressive images. I originally thought I would shoot 24p, and buy Cineform NeoScene to extract the 24p from the 60i data, and then edit the 24p to Blu-ray.

After playing more with the camcorder, I realize shooting native 1080p60 is a much better image, and you have more features available to use.

So, being as how Blu-ray will not support native 1080p60, what is the best way to convert this so I can permanently archive to Blu-ray, and still retain the progressive fields? Blu-ray doesn't even support 1080p30 AFIAK. I think I'd be OK with 1080i/60, if I knew every two fields came from the same frame originally captured. This means I'd have to discard 50% of the captured frames (somehow).

Any ideas?

if i were you i would resize to 720p60. probably you won't see difference. 1080p60 belongs to 4.2 profile. blue-ray is 4.1

I may have to go the 720p60 route. Would kinda suck, as all the gear I have supports 1080p, except for the stupid disc format :(

I'll be using Nero 10 starting tomorrow, if that helps with any suggestions on re-encoding/editing.

i aways convert m2ts to mjpeg avi (q2). in mean time i deinterlace. once i have progresive 1080p50 then i use sony vegas. edited footage is compressed to lossless avi (ut video codec) . at the very end i resize to 720p and encode to avchd with ripbot264

It depends on your content. If you have lots of fast motion etc, you should probably downsize to 720p60.

In fact, you should do a comparison with 1080p60->720p60->1080p60 (to simulate upscaling a 720p60 bluray disc) vs native 1080p60, and see how much spatial resolution you really lose.


FFVideoSource("1080p60source.ts")
a=spline36resize(1280,720).spline36resize(1920,1080)
interleave(a,last)


Take a peek. If the detail hit is too much you can interlace your 1080p60 footage to 1080i60 and keep the spatial resolution in areas without much motion.

SeparateFields().SelectEvery(4,0,3).Weave() will do the trick...

Of course, then you're committing a cardinal sin - producing more interlaced footage :devil:

Interlaced = Evil! :D

Since I'll be filming a baby, eventually fast motion will come into play.

Then 720p60 FTW :)

Or you could just forget it and hope that 3D blu-ray players support higher profile levels. In the mean time you could try different streaming solutions.

I must disappoint you, there is no improvment in levels, resolutions, bitrates, just added support for MVC profile.

You may want to check my post in multiAVCHD's thread. (http://forum.doom9.org/showthread.php?p=1391672#post1391672)

You may also check your camcoders capability of exporting the 1080p@60fps to 1080i which is AVCHD/BD compliant. You don't need to do anything but export your 1080p shootings to 1080i using the camcoder itself.

Doing the encoding yourself will give better results than the camera could.

Oh, I really doubt that... Do you have the camcoder? And why would software 1080p60fps -> 1080i30fps would be better?

And you don't even need a PC to do the conversion, not to mention the codecs, convertor programs, etc.

There's a better encoder on the PC than on the camera.
