What is MPEG video Component Version 2 means ?

[vidyarathne]

hello i found MPEG 2 video file.and it's in NTSC specification.but media info shows its video standard as "Component".what is that ? and how can i change that to NTSC without loosing video quality ?

[vidyarathne]

can anyone help me please ?

[manono]

I actually tried to figure out what it meant and thought it meant it was an MPG at first, rather than authored for DVD. But I was wrong. Any M2V I mux as an MPG also shows as NTSC, My suggestion is to author it for DVD (Muxman), perhaps after demuxing it, followed by demuxing it again (PGCDemux) and I would guess the M2V will show as NTSC then.

Why is it so important to you that it show as NTSC in MediaInfo anyway? Maybe that's what Womble writes into the header after it gets finished. But I don't have Womble and can't test. Maybe someone else can.

can anyone help me please ?

It says 720x480 at 29.97 fps, that is NTSC!

I always find it gratifying to log on here and read a post by a REAL expert.

Better than that, this EXPERT should have read the topic first.

Now to answer the question that was raised.

I would guess that this is Womble's way of stating the color space of the video 'Component' = YUV

Even so, we should see the full mediainfo report and not just a few lines of it.

I don't follow you, DB83.
This is correct: "It says 720x480 at 29.97 fps, that is NTSC!"

The word "Component" makes no matter.

[poisondeathray]

The OP's 2nd question was : "how can i change that to NTSC without loosing video quality ?" , I think that's what tonypeter was addressing, not the 1st question about why mediainfo says "component" instead of "NTSC"

I think his point was that we already know it's NTSC. That's not the issue. For some reason the OP wants MediaInfo to show it to be NTSC. That was the original question and I suspect it's due to something Womble did, but can't verify.

Exactly.

A different view from mediainfo may help.

[poisondeathray]

a screenshot of the gspot results might help as well

I ran a few videos through womble made some edits, but nothing about "component" on the exported video

[lordsmurf]

This sounds like one of those asinine things that gets asked in IT.

I remember the VP that wanted the Windows splash screen change/removed, because he didn't want to "advertise" for Microsoft to all of his employees. Easily one of the most dumbass requests I've ever heard.

Well that 'C' word is there. And no reference to it in the specs for mediainfo - that just says NTSC or PAL.

Blonde moment time. Is it possible for a video camera to shoot digital component video as 720*480 29.97fps. Write that 'C' word in to the file-header etc.etc.


I was thinking that even some UK cameras shoot at 'NTSC' spec.

Just a thought. Do not shoot the pianist.

this video is not from video camera.its from a DVD !

[DB83]

A dvd !!!!!!

That does not add up. A dvd can either be PAL or NTSC. My friend,above, determined that Womble in the ordinary sense does not write 'Component'

I will throw another theory in to the hat then. Someone, I assume this is not you, had a dvd and recaptured that in to a PC using Component Cables.

So maybe, just maybe, the capture hardware/software left its mark on the video which was picked up by Womble.

The bottom line, as has been said several times, you have an NTSC video. It is dvd compliant. Maybe I missed this but does it play without any issue ?. If it does then its akin to using a sledge-hammer to crack a nut if you just want to re-encode that - and lose quality - merely to see the word 'NTSC' instead of 'Component'

Just for the notes, here is a copy-n-paste from TMPGEnc's Help File:

Video Format

Select the video format for the output. NTSC is usually used.

Component: Component video

PAL: Europe and Asia, less Japan.

NTSC: Japan and North American video format.

SEAM (sic): Russian Television

MAC: EU television format.

Unspecified: Unspecified

[Cornucopia]

What I don't understand is why get so worked up about the presence of some metadata like "NTSC" or "Component"?

I mean, if some field in an MPEG got somehow marked "My Fat Ass", yet still played correctly in the media players I needed it to, I wouldn't care...

Those designators are usually indicative of compliance with a number of other factors (frame size, framerate, color space & order). Those are the factors that truly would make some difference here. Is there truly some playability problem going on here, or is this just someone being overly anal-retentive about tags?

p.s. (I actually DON'T have a fat ass)

[lordsmurf]

^ It has to be this.

I make a habit out of typing funny things into metadata all the time.
Almost nobody ever notices.
In the past 15 years, somebody has said something only once or twice that I can recall.

One of my favorites is to type in "I like pie."
I've done it ever since the Johnny Bravo episode first aired.

This sort of foolishness has been common since the 1970s.

Gee. I had to look up MAC. Adding a format that simply is not used today (and never really caught on) sure aint smart.

Makes me think now that 'Component' is akin to the NTSC equivilent of MAC for PAL. Hey, its there so I'll be a smart-ass and use it.

Other encoders do not offer it so that says it all.

And we still do not know if this mpeg actually plays fine.

[vidyarathne]

i mean i guess it's from DVD.may be it's from video tape. I'm sorry i really don't know.i downloaded it from the internet.

And we still do not know if this mpeg actually plays fine.

i played it in VLC and it plays fine.

Just let it drop then.

That's the whole problem.
