Smart render HQ clips from EX1?

megabit wrote on 2/3/2008, 2:54 AM
Did anyone achieve that? I mean, having the output Mainconcept MPEG-2 set to 1920x1080, 35 Mbps max, 25Mbps average will always recompress a HQ 35Mbps clip from the EX1, even with no edits at all - why is that?

Never tried to be honest.
I'm just thankful that Vegas can cope with it at all, it's one of the few NLE's that can.
Perhaps part of the problem is that it's VBR, all the current smart encode is CBR as far as I know.

Of course you mean 1920 x 1080.
megabit wrote on 2/3/2008, 4:40 AM
Sure, Serena - 1920x1080 it is. And Bob, I guess it's logical the VBR might simply not be supported by the smart rendering mechanism - you're right.

You need to render to mxf, not mpeg-2.
There's a HQ 35mbps VBR template but it's 1440x1080 and the size is greyed out. Strange.
As I thought smart render does not rely on the render codec.

Bob, now you got me interested - I meant final rendering for Bluray; as such it needs to be mpeg-2, doesn't it?

For the 1440x1080 50i mxf material, smartrendern works fine - but not for the 1920x1080 50i mxf material (since here we miss the reqiured output template)...

My PS3 will not play .mxf files so no big screen viewing. Seems Blu-ray format is only option. Why does Vegas not have a 30p template? For data disk, why not render back to mpeg4?
farss wrote on 2/3/2008, 12:03 PM
At a guess the smartrender of mxf is for trimming clips back to XDCAM disk. As XDCAM disk doesn't support 1920x1080 as yet that's maybe why Vegas doesn't do it either. It's still be nice if it did for archiving though.

Thought I'd bump this up a little - has any one found a solution in the meantime? I mean, the MPG2 template needs to have the right bit rate settings; while 35Mbps as the max setting seems OK, what average and medium values did you try?

Ive been wondering about this same issue myself in this thread http://www.sonycreativesoftware.com/forums/ShowMessage.asp?MessageID=583382&Replies=26.

Ive tried most of the MPEG2 ready templates but I get a nasty color banding on scenes that fade to black.

Ive been writing with Sony support but they simply stated they dont know if 1920x1080 MXF rendering will be available and suggested I ask help via the forum for a workaround :)

Sami,

I think you have never explained what you mean by "color banding".

The template developed in that thread works fine, but as said earlier: no smartrendering takes place here.

You could try to increase the video data rate, maybe that helps (but since I do not know, what you mean by "color banding", I do not know if it will help).

And yes: the Sony support will not know maybe, and if they know they will not be allowed to say something...

Hi Wolfgang,

Sorry I thought colour banding was fairly regularly used term when it comes to compression artifacts. http://en.wikipedia.org/wiki/Colour_banding The gradients are not smooth but show compression artifacts where the color changes "steps" into another instead of smooth gradient.

I think the colour banding is a phenomenon of its own, not connected with whether the EX'1 HQ clips can be smart-rendered or not in Vegas Pro 8.0.

And yes, I'm getting them, as well - for instance, when an object is bright but out of focus, and not stationary, its colours are banding very bad indeed. I tried rendering from a 32bit project - didn't help.

On the DVINFO EX1 forum, there was a thread on colour banding in special framerate modes - but nobody's mentioned it in relation to regular recording. Therefore, I wonder if it's an EX1's, or Vegas thing...

Just checked in Edius 4.6 - the banding is there, as well!

Check your setting. One thing about Vegas 32bit and the EX1 I love is wide blue skys wittout the banding I got with HDV and 8bit.
megabit wrote on 3/24/2008, 2:32 PM
As I said Mike - no difference between 8 or 32bit renders. Same thing in Edius... And no, with my V1E's HDV I never saw this kind of banding (no matter which NLE settings I used).

Take a look at the short clip (full resolution); the object in the background shows it very distinctly (it can only bee seen with unsatble shots / moving objects):

Actually I just noticed that when I apply a fade to material on a vegas timeline it has color banding already on the preview window.

Preview is set to Best (full). No effects are added. Just one video track with the original video that looks perfect. Only thing is the fade added on the timeline.

I also tested a few renders and I get the same banding on the timeline, rendered to MPEG2 and uncompressed quictime as well!

My project is 8bit and 32bit gives same results.

-EDIT-
By the way I can only see this banding on fades to black.

Megabit: What codec? Are you using Cineform NEO-HD? If not, get the trial and capture again. Capture the mpg4 files directly from the SXS card, convert to avi and dump directly in a 32 bit project.

Hello All
I have found a way to view nearly native clips from the EX1 on a PS3.
I say nearly native as the audio has to be rendered but not the video.
Use Clip Browser to bring clip into Vegas.
Download MXF Desktop, if you don't have it, from Snell & Wilcox.
It is free on request via a link at DVi XDCam EX CineAlta forum.
This unwraps MXF files. It also enables MXF playback on WMP.
You will get an .m2v and 2x AES files. Rename the .m2v to .mpv.
Import the mxf into Vegas 8 Pro and render the audio to AC3.
Download and run TSMuxer. Select both the .mpv and .ac3 files.
Create a .ts transport stream.
This can be renamed .m2t to run from a disc or drive on the PS3 or rename to .mpg if using a network connection.
I have not tested it over the network yet so not sure if 35Mb will work Ok. This could also be used to make a non rendered Blue ray disc.
Unfortunately this is long winded and does not allow editing but if you want to see video untouched by rendering it is the only way I have found. I would be much happier if Vegas would smart render.
Cheers
Malcolm

Sami, I do not know if that can be avoided with 8bit material and and a limited colorsampling at all. And it could also be a question of the HDTV used.

I have now tested a file made by my method above for making 35MB HQ .m2t files without re-rendering the video and it plays ok accross the network to the PS3.
