upscaling question

L8R wrote on 6/27/2011, 8:01 AM
I shoot all my video on my FX1's @ 1440x1080 60i.
I edit with the same project specs and if I put it out to blu-ray use the same template.
However If I wanted to upscale this to full 1920x1080 60i. What template would work best?
I am thinking that I would use: Blu-ray 1920x1080-60i, 25 Mbps video stream
change field order to progressive.
Constant bit rate of 25,000.

Then with DVD A set the properties to:
Blu-ray disc
25 gig
MPEG-2
Bitrate? default is 18. would I put this to 25 to match the source file?
16:9
1920x1080
Frame rate: This is where I'm not sure what to do....
Do I put this back to 29.97 interlaced or to 24.progressive?

I have burned a disc already changing it to 24 progressive and it seemed choppy.
Plus it wantes to recompress my m2t file, not sure why it wants to do this?

Can anyone help please?

As you're only scaling 1440x1080 to 1920x1080 you don't need to do anything. Just render your 1440x1080 footage to 1920x1080 at Best.
Really all that's happening is the pixels are being stretched horizontally and rendered to square pixel exactly the same as when they're display. I wouldn't even call doing that "upscaling"

What is the benefit rendering with the 1920 x 1080? Mixing HDV with AVCHD? Or is there another reason?

I'm still in the word of downscaling HDV to DVD world -- learning about Blu-Ray a little at a time.

Thanks Bob,
How about the properties in DVDA?
Should I keep the default setting of 18,000 or should I put it to 25 to match my rendered file?

Kimberly,
I have clients that want to be able to put this blu-ray of their wedding in their player and watch it at full 1080p. It's only taped at 1080i.
I've just heard that de-interlacing it helps with any strifing that may occur during pans etc.
I could be wrong though.

If it was shot at 1440x1080 60i then put it on Blu-ray at 1440x1080 60i and let the client's playback gear do the deinterlacing and stretching. It should make a better job of it than Vegas.

Unfortunately DVD Architect always recompresses 1080i HDV no matter what you do. It's basically an oversight/bug. Adobe Encore and TMPGenc Authoring Works will smart render it. I use Authoring Works and if I want to complete the authoring in DVDA (e.g. I want more than 2 subtitle tracks) then I retrieve the rendered m2ts files from the Blu-ray folder and DVDA will accept those without re-rendering.

@Nick

Can you see a noticeable difference on a HDV Vegas smart rendered Blu-ray over using one of the Blu-ray templates in Vegas? Is it worth the effort of buying and unsin Authoring Works?

Tricky one. Gut feel is that allowing DVDA to re-render your HDV is probably good enough unless you plan on doing this often.

A good way to judge would be to make one with DVDA and then compare it on a big screen up against output on the same screen played straight off the tape in the camera.

Note that besides the quality, the speed of smart-rendering in Authoring Works is also a benefit, if you do this a lot. It's pretty easy to use too. However it's limited to 2 subtitle tracks, and it's impossible to do a "resume" in the menu, so sometimes I bring the final .m2ts files back into DVDA to do fancier authoring, and DVDA doesn't re-render those.

One other thought. In later versions of Vegas you can also smart render HDV to Sony MXF or to Sony XDCAM EX and the quality of the re-rendered parts is higher than rendering HDV via the MainConcept encoder (see here). It would be worth seeing if DVDA will open either of those formats. If so, that should help the quality. You never know, it might even smart render them, which would be a major result, but I doubt it.

I've had no luck getting current DVDA to accept XDCAM EX Files at all, or MXF files without rerendering.

Oh OK, sorry about that and thanks for letting me know. Well, the quality of the result might still be higher via MXF than via HDV if significant parts of your timeline require non-smart-rendering. Compare the results of the 2 codecs on the timeline for a part that has fx or titles or transitions on it.

I did buy Authoring Works and Vegas smart-rendered HDV looked slightly sharper and better overall than Blu-ray template in Vegas. AW does not list mxf as supported but does support MP4. I will try a XDCAM EX file next to see if it will work.

Edit: Authoring Works will not accept XDCAM EX MP4 files.

@Nick

I can't seem to get the m2ts files from AW4 to work in DVDA without rerender... what's the trick?

It's ages since I've done it but I did it in 2008 and re-checked it a few months ago.

Read this thread. The method I used is in my post of 4/22/2009 6:07:44 PM.

Further discussion in this thread.

edit: Apologies for not linking you there earlier. I forgot the demuxing part.
