Thank you John, but it doesn’t work properly.

Render produced a jagged deinterlaced file in both templates I tried.
And in case of Sony AVC/MVC file, it produced an MP4 file with a frame rate of 59 frame/second, so it loks like it doubled NTSC frame rate.Even if this template creates a frame for each field results are awful.

Templates used:
1) Main Concept MPG2
Program Stream NTSC widescreen
Video: 29,970 fps, 720×480 Upper field first, YUV, 6 Mbps

2)Sony AVC/MVC
Memory Stick SD NTSC widescreen (6256 Kbps)
Video: 29,970 fps, 720×480 Upper field first, YUV, 6 Mbps

I am at a “no way out” situation as any deinterlacing method I’ve tried (yadif, Fieldskit, Mediacoder, etc) gave me a jagged file.
And, thou’ I read that MPG2 could mantain file interlaced, encoding does not behave in such way.

Any idea? thanks.

Hi John:
Thanks for replying

Original file to be processed is:
Streams
Video: 00:16:23,816, 29,970 fps interlaced, 720x480x24, DV
Audio: 00:16:23,816, 48.000 Hz, 16 Bit, Stereo, DV Audio

I choose the following Project:

Template: NTSC DV Widescreen (720×480, 29,970 fps
Field Order: Lower field first.
Pixel aspect ratio 1.2121
Pixel format: 32 bit floating point (video levels)
Full res. render quality: Best
Motin Blur: Gaussian
Deinterlace Method: None

Other details:

I noticed that when I add the file to the timeline, Vegas wants to adjust to Deinterlace Method: Blend Fields

I tried to render to diff. templates:

1) Main Concept MPG2
Program Stream NTSC widescreen
Audio: 224 Kbps, 48.000 Hz, 16 Bit, Stereo, MPEG
Video: 29,970 fps, 720×480 Upper field first, YUV, 6 Mbps
Pixel Aspect Ratio: 1,212

2)Sony AVC/MVC
Memory Stick SD NTSC widescreen (6256 Kbps)
Use this setting to create an NTSC standard definition 16:9 Memory Stick compatible MP4 file.
Audio: 256 Kbps, 48.000 Hz, 32 Bit, Stereo, AAC
Video: 29,970 fps, 720×480 Upper field first, YUV, 6 Mbps
Pixel Aspect Ratio: 1,212

Any clue about what I am doing wrong?

Hi People:

As nobody answer my previous post, I think perhpas I didn’t explain myself.
Thou’ I render lot of files, I am a totally amateur.
Since I don’t like the result of rendering a DV 720 x 480 widescreen file to AVCHD in order to make a blu ray disc (cause deinterlacing results are really jagged), I decide to don’t deinterlace and let the player/receiver to do the scaling and deinterlacing.
But… encoding to MPEG2 (720 x 480, interlaced) is giving me jagged pictures as well.
I originally thought that Vegas will render each field as interlaced, so no deinterlacing will be involved. But results are also so jagged like if deinterlacing was applied anyway.
So I am missing something but I don’t have a clue about what it is.

Any help will be appreciated.

[John James]

Can’t be more confused.
¿Is it not an MP4 file anyway?
How I get rid of the Quicktime “envelope” to do a proper smart rendering.
Maybe usinga YAMB software to get the MP4 file into a different “envelope”?.

[John James]

If I had the chance to get a bigger file with more data in it I will try to take that option.
On Vegas, SONY AVCHD template offer a 21.999 mbps selection. Anyway, It just hung again at 46 % of the process an hour ago. Why it did not hanged up with the 16 mbps template?

[John James]

Hi steve.
yes, it is Vegas Movie Studio 11 HD Platinum, with last february build.
No, at 16 mbps it did not crash. But output file is only 8 GB, and considering that a BD is about 23 GB in size, I want a heavier file, with more data in it.

[Stephen Mann] “Any playable format -any playable format- will be compressed and a poor candidate for further editing”

I do not want to do any edition later. Just the plain concert from beginning to the end, one cam, no fuss. I will just mark the chapters later and a menu.

Stephen, I just want to know if there is any AVCHD configuration that do not degradate the original DV file. That was what I supposed before start with this: AVCHD won’t show the grade of degradation that usually shows DVD. I was wrong, I guess. Too much hype with the Hi Def BD format, but it can not keep a simple DV image quality safe.

[Robert Lin] “My understanding is that AVC gives a better result than Mpeg-2 for the same file size; hence I use AVC.

I’m sure you’re aware of this, but it wasn’t clear from your post: While doing your tests you can just render a short section and see how it looks”

Thank you Robert.
I rendered the whole concert because I suposed that it will be “the deal” in the first try. To my surprised that was not the case.
Checking the 3 files already produced, I think I agree with you that AVCHD could looks a little better than MPG2 file. Even, last MPG2 file tweaked to keep a 33 mbps average transfer rate, with I-frames set to 32 value, and B-frame to 7 value, resulted in an awful big 18 GB file that looks like an old VCD enconding (not joking, full of big squares on the whole file). Obviously, I did something wrong when I tweaked the Main Concept MPG2 template, but I’m not sure where is the big mistake.
I will try now tweaking the Sony AVCHD 16 mbps template to rise the final file from the first 8 Gb file produced to a more heavy (less compressed) file. Let’s see what happens. It will take another full day or so of processing.

[Stephen Mann] “You are losing quality because you are re-encoding.”

Well, I know that.

[Stephen Mann] “Why can’t you just save the master file?”
Thank you stephen.
I have the original tape, and I have already a DV copy of it ina BD disc. But you’ll never playback a DV file again in your living room device (DVD/BD player, if any can playback DV codec, which I doubt, not mine as far as I know)if you have to scroll de search bar to catch a given part of the concert recorded.
I just want to have a disc that you can throw into a machine (Blu ray player or whatever) and anybody can watch it, with virtually no quality loss.
That’s why I said in part of the post that if there is only a way to add menus in a DV file that can be read in a Blu ray machine, that will be “my heaven”.
As I can not find some of the kind yet, I tried the AVCHD conversion, hoping a better transfer than an ordinary DVD. But I discover that, even using best templates, degradation is still there in a noticeable way. So I am a bit surprised. Maybe I am still a little naive.
Anyway, I can accept any idea, no matter how weird it can sound.
Thank you.
