Does anyone know tools for previewing safe area?
Hello ? If anyone can type a list of tools that can preview the safe area of TV (the overscan "issue") of a video file it would be nice :).
EDIT: Sorry! This sshould be on KDVD forum. DIalhot, could you move it please? |
You want to have it drawn onto the picture while you look at the video ?
|
|
The only tool I know is DVDLab that give you that on the menu drawing screen. But it does not display it on a running video, just on a still picture.
Note: where do you find you image ? |
#---------------------------------------------
Colorbars(720, 480) Subtitle("Top Center", align=5) Subtitle("Bottom Center", align=2) Subtitle("Top Left", align=4) Subtitle("Top Right", align=9) Subtitle("Bottom Right", align=3) Subtitle("Bottom Left", align=1) #---------------------------------------------- Save that to an avs script, and run it. -kwag |
Actually the correct values are :
Code:
Colorbars(720, 480) The safe area is an authoring notion that take in account the "safe" place to put a button else you won't be abble to select it. It's something more than only the overscan issue. |

http://www.digitalfaq.com/archives/i.../2005/07/6.jpg Adobe After Effects. You can create a composition in any resolution you want to , load up the video and check safe area button. It only suppoorts lossless video compression. So I used huffyuv codec and encoded a small amount of the video (with overscan=2). I heard you can change the FOURCC of the video too... Adobe Encore DVD has a safe area option too. But it only supports full dvd resolution videos: http://www.digitalfaq.com/archives/i.../2005/07/7.jpg |

Did you actually play that script on your monitor, and read what is displayed :lol: -kwag |

Now Im not in home, but later I could explain it further. Meanwhile, maybe someone of our partners could post the correct script. |

And with your values, bottom string are at the top, and top ones are in the middle !!! My values : (you can see that I did a little mistake on the bottom line) http://www.digitalfaq.com/archives/i...2005/07/12.png Your values : http://www.digitalfaq.com/archives/i...2005/07/13.png :!::!::!: (note : avisynth version 2.5.6) |
Phil are right Karl, you messed values.
Anyway, values given by Phil are opposite as showed in http://www.avisynth.org/Subtitle I mean avisynth subtitle page: 1,2 and 3 bottom, 7,8 and 9 top Dialhot: 1,2 and 3 top, 7,8 and 9 bottom (fixed Dialhot error mentioned by himself) |
Well, this is the weirdest thing I've seen 8O
That's screenshot I posted was taken with MY values :!: I may have some codec screwing up things here :roll: -kwag |
ffdshow tells me the cip I generate with avisynth is RGB32. If yours is YV12 or YUY2, this can explain the vertical flip-flap.

I want to do what said in a previous post (overlay) but I don't know what linked pic I must to use with PAL or with NTSC neither at what resize adjust each one. I mean: Are 720*486 safety areas for a PAL 704*576 resized stream? Are 720*486 safety areas for a PAL 704*576 resized stream? |
Well:
http://www.digitalfaq.com/archives/error.gif 1 - Right click previous picture and save it as 720x486.jpg 2 - Do a script similar to following with your own resolution values. Code:
Mpeg2Dec3dg_Mpeg2source("E:\DVD Authoring Working Folder\CAPChocolate-NA-108.55.d2v",cpu=4) Width and height values are configurables. 3 - If you keep 720x486.jpg in same folder than avs script you can leave this line safe_area=imagesource("720x486.jpg").flipvertical( ) so, if not you need to modify it as: safe_area=imagesource("path to\720x486.jpg").flipvertical() 4 - Doesn't matter what resolution is your target, dont edit and change jpg resolution, only change avs script values. A pic as example: http://www.digitalfaq.com/archives/error.gif A stream as example: SafeArea.m2v |
I was out for some days :D
Thanks very much to all ^_^ @Prodater64: Thanks for your solution! I use avisynth on my animes but never noticed the possibility to use overlay/opacity with images and videos :D Avisynth is really P-O-W-E-R-F-U-L ._. Anyway. That image is 720x480. How could it work (correctly) for a video in 352x240 for example ? You said: Quote:
thx ^_^ EDIT: this apply for PAL & NTSC ? |

You can edit values that are after Width= Height= with legal values. If you use gripcrop as I wrote in previous post (or another resizer that takes those values. I mean you must to replace 352 and 480 in resizer string for width an height words), you don't need to resize the jpg file. Just give it a try. I think is for both pal and ntsc, maybe a little difference, but I think won't be any problem. Do you understand? My english is very bad. Just test it. |
@Prodater64
Pretty sorry! >.< . I saw now what I missed: Code:
overlay(safe_area.bilinearresize(width,height),0,0,opacity=0.35) Now it makes pretty sense at all :D :D :D Quote:
PS: I do not have my own StandAlone DVD player. So I will need my friend to test it. I just burn my animes to my friends :D Quote:
TIP: Here I use www.babylon.com to help me with my english. If you wanna too, install the english-english-spanish dictionary :D (If I Recall Correctly, you are from Spain) |
Thanks for the link.
I knew it, but many times those translations are not good. Anyway some times I do use google translation tool. |
PS: avi is NOT illegal/ripped stuff
Hello. Just a comparison: the @Prodater method. And the "Adobe" method. AVISource: 640x480 Output: 720x480, overscan=2 Script used: Code:
AviSource("C:\LOGO\watcha\bleach_xvid3.avi", false) http://www.digitalfaq.com/archives/i.../2005/08/3.png and ACTIVATED: http://www.digitalfaq.com/archives/i.../2005/08/4.png and the very little difference between both: http://www.digitalfaq.com/archives/i.../2005/08/5.png The lines that are "whiter" are from Adobe best regards sparskter |
@sparskter: And what do you think of my method. Is it enough good or not?
I just did it as you ask for it, but I don't use it for nothing, so your opinion would be very useful. |

Code:
a=AVISource("C:\LOGO\watcha\bleach_xvid3.avi",audio=true) Output: 720x480 I learned that 24+24 + 672 must be equal to 720 (and the width of border must be multple of 4) And 33+33+414 must be equal to 480. And so, I can get a very precise result 8) And for that I need to do many tests using avisynth/virtualdub and of course using the safe area to final adjust it :D best regards sparskter |
