Video CODECs

[biferi]

I am using Win7. 64 Bit and Movie Studio Platinum 15 to Edit and Make my Movies.

My Camcorder Takes Video at 1080p 30 FPS Widescreen.

I did all my Effects and everything looks good.

Now I go to Rander As and I Pick Format MPEG2.

But for the Template I do not know what to Pick?

1. is Program Stream NTSC Widescreen.
I know NTSC is the USA Standard this is ok but what is Program Stream?

2. is DVD Architect NTSC Widescrean Video Stream
This is good to but what is Video Stream?

3. is DVD Architect 24p NTSC Widescreen.
What is the 24p for?

My Videos will be used to Make a DVD so I know I would want my Video in NTSC because I am in the USA.
But the Templates I gave that say Video Stream I do not know what that is.

And the Template that says 24p NTSC I do not know what this is.

NTSC is for the USA and it is for 29.97 FPS so what is the 24p for in the Template?

Thanks for all the help.

Since you are making a DVD, the DVD Architect NTSC widescreen preset is a good place to start.

You do not want 24p. You want 29.97. Sometimes it is called 60i or 59.94i.

Be aware the picture will not be as clear because you are reducing it to DVD standard 720x480. It will bother you a lot. Nobody else will notice.

that's assuming you have dvd architect and that you are going to use it to author a dvd? if you do it is looking for dvd mpeg-2 compliant video and audio streams for it's input. so either choice should be ok as long as it's outputting both audio and video streams.

[biferi]

Ok I get everything you are Telling me and Yes I do have DVD Architect.

But the Template that says
DVD Architect NTSC Widescrean Video Stream.

Why does this say Video Steam and the others just say
DVD Architect NTSC Widescrean?

[Cornucopia]

You know, you could always drill down into the template and see for yourself what the settings actually are.

However, to make this shorter, from memory, the one that says "...video stream" is JUST the video steam (mpeg2 codec, using IIRC the *.m2v file extension). It's just a raw, elementary stream, whereas the other DVDA one has the video stream and the accompanying mp2 or ac3 audio stream ALREADY muxed together into an mpeg program stream (*.mpg). Both are acceptable in DVDA, but one assumes you may be exporting separately to ac3 or even perhaps lpcm, so you have more flexibility in authoring.

Btw, you can also customize those templates to settings that might be your personal favorites. I know I did. However, I recommend only doing this if you fully understand the ramifications of any changes you might make.

DVD authoring software likes it much better (assuming), maybe it is less prone to glitches, when you load video and audio stream separately.
When you import video.mv2 and audio.ac3, software just grabs them both and mux them into VOB. If you have them both in a container, it could be a potential problem, more or less.

And as was said by Cornucopia, those templates are basically a suggestions, you can customize them, some templates more, some less, but not if you want working DVD, you do not customize them, keep those specs as they were set for you.

DVDA has something in settings to set , that you do not want to re-encode those loaded files, not sure where it was. You make sure that they are by DVD specs using those predefined templates in Vegas for video and template for DVD studio stereo AC3.

Thanks for all the help.

One Last this what is DVD Architect 24p NTSC Widescreen.
What is the 24p for?

If this is NTSC DVD it will be 29.97 FPS or just 30 FPS.
So what is the 24p stand for?

[jagabo]

Film is shot at 24 fps. When shown on NTSC TVs 3:2 pulldown is applied to create 29.97 fps:

Pulldown can be hard (applied before encoding) or soft (applied by the player during playback). The latter usually has better quality.

Use DVD Architect NTSC Widescrean Video Stream. That is what you use to create DVDs, regardless of whether you have or use DVD Architect to author the DVD. I have created several thousand DVDs with Vegas over the past twenty years, and that is the template you are supposed to use.

[Cornucopia]

Yes, ONLY use the 24p template if your source footage were from film. Is it from film? No? Then don't ever use it.

Ok I used DVD authoring NTSC Widescreen and everything is good.

After I Picked DVD authoring NTSC Widescreen I go down to the Bottom of the Screen and it Tells the Specs of how it will be Encoded.

720x480 NTSC then it sa the Field Order I get this.
Then it says 4. Mpbs is this the Video Bit Rate it will be Encoding it as?

If your source is SD video, then choose lower field first. If it is HD video then choose upper field first (which has been the default since Vegas 10).

4 Mbps is very low and I am quite surprised if that is the default. I've been with Vegas since version 4, and the default was always 6 Mbps. Four is too low. If the total length of your video is under 75 minutes, use 8 Mbps. Also, if you use any bitrate lower than 8 Mbps, make sure to turn on "two-pass." It will take twice as long, but you'll get better overall quality.

[biferi]

Sorry the Bit Rate is 6. Mbps.
And my CamCorder Takes in 1080 H.D. so I left it at Upper Field First.

It says YUV is this for the Color?
I know what RGB Color Model is but not YUV?

[jagabo]

Check your source's field order with MediaInfo. Pretty much all video is YUV.
