Resizing Problem OTA HDTV capture to DVD
 

Am having resize problem with a HDTV OTA capture to 720x480 DVD. The sides of the encoded m2v are cropped up to the "HD" logo on the lower right of the screen. The full screen plays on the PC, but not on the stand alone DVD player.

Edit Dialhot : do not paste the HTML links from imageshack but the phpBB ones.

You mean that the encoded m2v is read correctly on the PC but the imaged is cropped when you what it on the TV ?

That means that you can't post a snapshot of the problem to let us see what is the result ?

Yes. The image on the TV is cropped on the sides, on the pc it is as shown. I could maybe record on vhs, capture into pvr-150 board and send. Or possibly take a picture. Don't know how it would show up.

The problem was identical with the shown avs and with an anamorphic one with tmpgenc set to 16x9. I am showing on a standard, non-hdtv, ntsc tv. There are the expected bars on top and bottom.

What are you using (tools and method) to look at the encoded m2v on the TV ?

It's like if you are looking an anamorphic DVD on a 4/3 TV set in pan&scan mode insteed of letterbox.

Edit: the best way to show what is on your TV is to take a picture with a cell phone camera and transfer it on your PC./ but you need a cell phone and a wire to link it to your PC :).

Thanks, Phil. :)

Authored with DVDLabPro with AC3 from DGIndex. Burned DVD. Viewed DVD on tv. Viewed DVD and m2v on computer (ok).


Will check tv settings. It is a Sharp 4/3, but has feature that is supposed to show enhanced 16x9. The DVD player is a Cyberhome 300 set to 4:3.

Will try to send photo. Like I said, picture just cuts off some of the sides. Could the DVD end up anamorphic with the avs above and TMPGEnc set to 4:3? (I ran DGIndex with ignore flags.)

Actually, all must be set in sync. Either :

- ask fitCD values for an anamorphic dest
- set "16/9" as target ratio in tmpgenc
- verify that DVDLab detects the m2v as 16/9 (it will author the DVD in anamorphic)
- set the standalone to display in 16/9
- set the tv to display 16/9 in this "16x9 enhanced mode"

OR

- ask fitCD values for an anamorphic dest
- set "16/9" as target ratio in tmpgenc
- verify that DVDLab detects the m2v as 16/9 (it will author the DVD in anamorphic)
- set the standalone to display in "4:3 letterboxed" (not 4:3 P&S)
- set the tv to display in 4:3

OR

- ask fitCD values for a 4:3 dest
- set "4:3" as target ratio in tmpgenc
- verify that DVDLab detects the m2v as 4:3
- set the standalone to display in "4:3 letterboxed" (not 4:3 P&S)
- set the tv to display in 4:3

DVDLab authors in anamorphic only if it detects that the m2v is 16/9. This is displayed in the "Assets" window.

Thanks. I'll try all this when I get home tonight!

There's something set wrong somewhere, because

DVD's made as FitCD anamorphic out settings and 16:9 in TMPGEnc

and

DVD's made as FitCD non-anamorphic settings out and 4:3 in TMPGEnc

produce the same results.

(The original OTA HDTV capture is 16x9.)

Can't photo, too much glare from screen. DvdLabPro shows 4:3. Approx 76 pixels cut from each side when on tv (checked by clipping in tmpgenc).

I don't see what is wrong in your settings on the PC. I can't tell for the settings on the TV set and the standalone. Are they the same that you used before ? Because I guess that this is the first time that you have the problem, isn"t it ?

Picture cropped to right edge of "D" in logo.

Picture cropped to right edge of logo box.

Picture cropped to half of "D" in logo.

Maybe someone already mentioned it but ....

http://img129.imageshack.us/my.php?image=fitcdjj5.jpg

in this screen the input is checked as anamorphic.
HDTV streams, espec. those 1280x720 are PAR 1:1 using a DAR of 1.7778:1, means no anamorphic, neither squarepixels, .... just PAR 1:1 quadrapixels.

So on hdtv 1280x720 or 1920x1080 inputs do check anamorphic OFF.

Resize 1280x720 to ----> 704x480, pad to 720x480 and simply switch "16:9" anamorphic in your encoder on. Easiest resizing by keeping max of source quality on a NTSC DVD-R

This is about the only combination I didn't try! Will do so tonight and post the outcome. I normally use anamorphic on settings from FitCd when I use 16:9 on first screen of TMPGEnc.

Thanks Guys :P

Tried Incredible's settings. Still cropping sides on TV. Tried with all settings on Cyberhome DVD Player and Sharp 4:3 NTSC TV. A few seconds of the HDTV source are at:

Also, I have a short clip from the vob from Incredible's advice above. It appears horizonally stretched on my pc.

That's normal : a wrong setting in Paranoia can explain an image streched or distorted but not a crop of the image, more over when this problems exists on the TV set only (not on the PC). The problem can't be elsewhere that in the TV or the standalone. And unfortunally we do not have them in our hands :(.

As a test, I'm going to output the dvr-ms from VideoReDo as a ts and process in HDTV2DVD. Will also try switching my connections from the DVD player to the TV to a s-video cable instead of the current components cables. Will also test on another DVD/TV combination.

I have never had problems with widescreen anamorphic or non-anamorphic DVD's, but something is going screwy.

Thanks, Phil :)

It is not stretched : you have to force your player to read with a 4:3 A/R as the VOB resolution is not really 4:3 (720/480 = 1.5, not 1.33).

This VTS is all correct. As I said, the problem is on the standalone or the TV.

Tested anamorphic, nonanamorphic and Incredibles settings DVD's on 2 TV's and 2 different brand DVD players (Cyberhome and Magnavox). Exactly same side cropping. On my main system, tried s-video and component output from DVD player at both 4:3 and 16:9 and TV at 4:3 and 16:9.

Same picture. Will try to test on a HDTV widescreen.

It's certainly not a hopeless thing. The DVD quality is outstanding and only some 40 or so pixels are cropped from each side of the 720x480 picure. I can live with this, but it is strange.

The file VTS_01.mpg that you send above is the one you put on the DVD ? I will author a DVD with that and tell you how it is on my TV (both 4/3 and HDTV one).

The VOB I sent was with Incred's settings. I have actually made several other encodes, including:

nonanamorphic in anamorphic out with tmpgenc set to 16:9
nonanamorphic in nonanamorpic out with tmpgenc set to 4:3

which would be best for you to test?

(Incred's was nonanamorphic in nonanamorphic out with tmpgenc set to 16:9.)

According to me the file you sent before is correct. If you tell my that this one gave you a cropped image on your TV, then I will author a DVD with it and see if I have the same. Else provide me an other file that you want me to test :).

I've tried so many combinations 8O . Let me reencode an original capture HDTV section as:

FitCD nonanamorphic in nonanamorphic out (I'll post FitCD screen) with TMPGEnc set to 4:3. This should be most "standard" settings.

OK?

Phil,

A seven second encoded m2v and the ac3 are at:

Also, my DVD player doesn't seem to like 7sec clips, so I authored in DVDLabPro as 2 movies with 2 menu items. Same clip in both. That plays.

How much overscan should I get playing this on a 4:3 TV?

Be carreful that this trick can introduce problems (animated menu are managed differently by the player than regular movie tracks).

Generally 2 ( = 16 pixels) is a value that fit to all screens.

Edit: will try your files this evening, at home.

Thanks, Phil :) I meant that I used the same 7sec m2v/ac3 to in 2 DVDLabPro movies. The menu was simply 2 text objects linked to the movies. No animation. Only did this because my player doesn't somehow like single 7sec movies.

So I tried your test (that is actually 3 second long, not 7 :-)).
The picture is cut few pixels at the right of the HD logo. That represents 30 pixels, more or less, whatever the player or the screen I use (my regular 4:3 TV set of my HDTV rear-projector).

I know that my system had a overscan between 2 and 3 (16 - 24 pixels), so 30 is weirdly big. But I don't find any reason for that.

Anyway I suggest you to encode with a resized (not overlayed) overscan of 2 (16 pixels) and see if this is better on your system.

Thanks Phil :D

I had thought of overscan, that's why I asked about the number of pixels.

I'll encode tonight with overscan 2 and see how it turns out.

Again, thanks for going to all the trouble! I really appreciate it.

No problem.
Just to know : what are you using to capture the original source ? Did you see that the file uses a 30 pictures long GOP and weird matrixes (Intra is the original MPEG2 matrix but Non-intra is all composed of the value 16).

dvr-ms captured with ATI OTA HDTV Wonder with MCE. I think VideoReDO has options while processing mpeg output. Any suggestions I can play with?

I would use a shorter GOP, 30 means a lot of B frames so a quality lesser than a standard DVD stream (length = 15 or 18).

For the matrix I don't know the effect of a non-intra matrix composed of only "16,16,16,16..." so I can't say.

Success
 

.

And the answer is .......................you are right, as usual! :D

I changed GOP to 18 (NTSC DVD) in the VideoReDo output mpeg options and created another source mpeg.

Made two test encodes, one with overscan2, another with overscan3.

Overscan2: Saw entire logo and and additional width of 1/2 the "D" in "HD".

Overscan3: Saw some more of the picture.

I'll opt for overscan2, as some TV's may not crop the same amount of pixels as mine and I don't know the effect on a HDTV.

I encoded as fitcd anamorphic out with tmpgenc set to 16:9, changed fps to film.

I am going to ask on the VideoReDo forum concerning matrices. I don't know how they are converting from dvr-ms to mpeg. I do like VideoReDo.

One more question.
 

Phil,

Having resolved the overscan thing, need an opinion. (Am still working with the Lost HDTV captures.)

I want to put four 42 minute episodes on a DVD. I can encode at CQ 90% as above, author in DvdLabPro (with Mp2 audio) and create a DVD that shows 91% in DVDShrink to fit to DVD.

In your opinion, would it be better to encode at a 85 CQ which does not require DVDShrink (fits DVD)?

I know that some time ago, there were discussions on the merits of processing with DVDShrink 2 times, etc. I want to avoid further testing and burn these things. 8O

Re: One more question.
 

I myself encode at 85% insteed of 90 half of the time, the loss in quality is not so big. Avoid using DVDShrink if you can.

Thanks, turned out CQ 85 with AC3 exactly filled DVD without DVDShrink. :D
