1080p avi to DVD (not HD-DVD)

[ontherocks]

First a basic question about terminology used.
1) The resolution of a video file is written or said as just "1080".
The "i" or "p" is written or said for the player. In other words video files are always termed as 480 or 576 or 1080. Whereas in players they use the term 480i/p, 576i/p or 1080i/p. Is that correct?? Or video files themselves can be interlaced or progressive too??

2) Which program can give me the complete information/properties of a video file. (Gspot doesn't tell if it is interlaced or progressive)

3) I understand that DVD standards for video resolutions are 720×480 (NTSC) or 720×576 (PAL). (i.e. 480i/p or 576i/p)
Is it possible to author a DVD with higher resolution video file and then play them in a regular DVD player??
I have a 1080p avi file. Can I author a regular DVD out of it with the exact same resolution and then play it back in my regular DVD player??
If so how??
(BTW I have tried a lot of programs to convert a video file with resolutions higher than NTSC/PAL to DVD vob, but all of them downconvert them NTSC/PAL or below. Its as if its inbuilt in the program to make the output .vob files to be NTSC/PAL or below.)

1) Yes, a video file's content can be interlaced or progressive.

2) Human Mind 1.0 is the reliable way to tell if content is interlaced or progressive. Inspect the fields in a motion segment and see if you get a new picture every field (interlaced) or every two fields (progressive). It's a little different for telecined video, but the idea is the same. Realize that a file's progressive/interlaced *content* may not agree with how it is encoded. That is why you cannot rely on flags and such, you have to inspect the fields with Human Mind 1.0.

3) No.

Thanks a lot for the reply.
Where do I find Human Mind 1.0??
Googling didn't give me any concrete results.

Last time I purchased it, it was just next to "elbow grease" ;)

It's the program that is currently running on the wetware inside your skull. To be a little less cryptic, you can use SeparateFields() in Avisynth to step through the fields. Then by looking at the fields and seeing when new pictures appear you can identify the signatures of different types of video. See here for more details:

If you can't help others because of your poor knowledge try keep your mockery to yourself.

I will try and see if I can get something out of it.

@ontherocks

I think he was actually trying to help you, in a humorous way.

Let us know if you have any other issues and I'm sure we'll both do our best to help you.

Good luck and welcome to the forum!

Sorry for this out-of-line pun, I just though you were kidding and following neuron2's joke.

Now that i made a fool of myself, let me try to answer your questions as best as i can with my poor knowledge...

First a basic question about terminology used.
1) The resolution of a video file is written or said as just "1080".
The "i" or "p" is written or said for the player. In other words video files are always termed as 480 or 576 or 1080. Whereas in players they use the term 480i/p, 576i/p or 1080i/p. Is that correct?? Or video files themselves can be interlaced or progressive too??

I tried, i really tried, to answer this question but my english just doesn't make it, the best for you would be to check the wikipedia page about interlacing.
Basically with a digital video file, you always get full frames, but if the content is interlaced every full frame will contain two interlaced fields combined.
It's up to you/the player to decide what to do with the content...


2) Which program can give me the complete information/properties of a video file. (Gspot doesn't tell if it is interlaced or progressive)

As neuron2 said, the best way is to separate the fields one way or another and check if they "seem" to be interlaced fields. (scene changes make it obvious)
Every other codec/container as a progressive/interlaced "flag" which could be displayed in clear by a program, but that doesn't warrant that the content is actually interlaced or progressive.
For other aspects of the file i would recommend avinaptic or mediainfo, you can find them in this forum.


3) I understand that DVD standards for video resolutions are 720×480 (NTSC) or 720×576 (PAL). (i.e. 480i/p or 576i/p)
Is it possible to author a DVD with higher resolution video file and then play them in a regular DVD player??
I have a 1080p avi file. Can I author a regular DVD out of it with the exact same resolution and then play it back in my regular DVD player??
If so how??

The short answer is no, dvd can only hold pal or ntsc/film content.
If you want to author a dvd from your 1080 avi, you'll have to resize it to one of the resolutions you stated.
As altering resolution is a less destructive process than altering framerate, choosing between pal/nstc should be based on the source framerate:
If your source is 25fps, encode in pal, if it's 24 or 30 fps, encode in ntsc (or whatever multiple of those numbers)
I won't get into the telecine process as i can hardly explain what interlacing is in 2 sentences.


BTW I have tried a lot of programs to convert a video file with resolutions higher than NTSC/PAL to DVD vob, but all of them downconvert them NTSC/PAL or below. Its as if its inbuilt in the program to make the output .vob files to be NTSC/PAL or below.

See above, you can't author a higher-than-sd dvd, otherwise it's not dvd-video and won't be playable in a standalone.
If you want to keep it high-def, burn it to dvdr and be able to play it in a standalone, you could try "hd-dvd on dvd-9"...but that would require and hd-dvd player.

(the "rule 6" guy deep inside of me would tell you "just burn the legitimate source you used to produce that 1080 avi content", but i guess that would also be out of line)

Is there a good reason why you posted THIS EXACT SAME QUESTION as in your post to the forums at http://www.dvdrhelp.com on the EXACT SAME DAY as you did here? For those who are interested see:
http://forum.videohelp.com/topic336337.html
Doing this makes me seriously doubt your sincerity. There's nothing to stop you from making posts everywhere on the same subject, but most people just post to one forum and wait for a reply and then if they don't get help decide to post elsewhere.
Doom9 forum members are not known for their kindness (see my quotes in the next paragraph) and this kind of behavior is not likely to make you any friends here.

By the way if you don't like the mockery you got, I understand, but all I can say is that I've seen a lot worse here at Doom9. People tend to behave better at dvdrhelp than here, but there are stronger technical people here, so you have to decide what's important to you - Greater technical help here but higher chance of insulting replies or less chance of insulting replies but somewhat lower technical knowledge at dvdrhelp.

You didn't realize that I was not kidding (I am a noob.....what else could I do if neuron2 writes something like that).
And I didn't realize that you were kidding. Truce :)

I am totally new to avisynth and would have to go through it to realize what you or neuron2 are saying.
I will try that out and the two other programs that you mentioned.
BTW from the other forums I got to know about determining "i" or "p" from the comb like appearances that you get to see in interlaced video files wen you play them. It was surprising to find by that method that the avi file I have is actually interlaced which I thought to be progressive.

See above, you can't author a higher-than-sd dvd, otherwise it's not dvd-video and won't be playable in a standalone.
If you want to keep it high-def, burn it to dvdr and be able to play it in a standalone, you could try "hd-dvd on dvd-9"...but that would require and hd-dvd player.
Yes I thought of that and tried it too (i.e. authoring a HD-DVD, then creating an iso image and then burning it to a DVD-5). But then it won't play in my regular DVD player because the formats are completely different. (HD-DVD has .evo files rather than .vob files) :(

It was surprising to find by that method that the avi file I have is actually interlaced which I thought to be progressive. It's not always true that if you see the combs, it is interlaced! That's why you have to separate the fields and look at the pattern of new pictures. There is a process called telecining (3:2 pulldown) that takes progressive video and causes it to look combed for two frames out of every five. If you deinterlace 3:2 material you will mangle it horribly. For such material, you need to apply inverse telecining (IVTC).

You can also have progressive material that looks combed because the fields are out of alignment by one. Again, if you deinterlace it you will mangle it. You need to do field matching in that case.

I wish it were simpler, but it's not. :)
