test disks

Update february 7, 2009

I made these test disks in 2008. The disks were in the back of the thread, last post.
I decided to link to the disks to the first post today.

The disks were designed to be used with a resizer, as well as the filter you are testing.
I use seesaw and ffdshow spline resize.

In the test pattern is a moving image with a hidden pattern that is revealed with the resizer and seesaw plugin.
It's designed for enhancing dvd movies played in ffdshow in realtime, but they may be of use to you as well.

There is a interlaced and non interlaced version. As well as a pal and ntsc version of these.
It's a nice test disk to test sharpeners and dehalo filters.

I provided a example picture showing a nice result.
I assume that if you use the test disk you will see the similarities or differences.

The test disks are not documented to go into detail on why my picture looks better, or worse than your result.

When you see your test result, what you do after that is up to you.
I can't be expected to tell you what to do after that.

My point in saying the above you first use the test disk then you figure out what you do then.

April 12, 2009
Today I made a new version of the test disks.
I will post the links to them below.

Here is a example picture with some text telling you how the pattern should look.

- How to burn the disk to cd or dvd so you can play it on your dvd player

a.) Download a test disk
b.) Unzip it
c.) In the unzipped folder are two folders: audio_ts, video_ts.
You can use your burning program and make a data disk putting these two folders on the disk.



3D Test Patterns.

Pattern one is looked at with one eye closed, and the open eye looks where the pointer says to look for that eye.
What's being pointed at is black and white bars. Look at the color of the black or white bar and compare it to the IRE scale of white to black squares next to it.
The black IRE square the black or white bar looks like is the amount of crosstalk your TV has.

Pattern 2 is only supposed to have white in one bar at a time, anymore than One white bar and your seeing crosstalk.
You'll need to either guess if the bar is too wide or use a dslr camera white the shutter speed at 1/1000 and take a photo of the screen white it's playing the 3D test pattern.

Both patterns are in side by side, 16:9 ratio, left eye first.

Pattern 3 is in 8x8 and 16x16 pixel squares.
It is in side by side 3D, left eye first, 16:9 aspect ratio 30 seconds long.
It has these three frame rates per eye: 50, 59.940, 60.

These are easy to use. Watch the 16x16 videos first, and look for the bars to become lit up wrong.
The bars aren't supposed to stay lit up when the white square isn't in it.
The white square is exactly 16x16 pixels, it's a square, so if you see a long white bar inside the pattern it's showing a error in the TV.
Or maybe you'll get color in the boxes, or maybe the boxes will get partially filled after the white box left it, these are all errors that it's not working properly.

I made these tests for the TV manufacturers to use so they could implement motion compensation, or the soap opera effect 120Hz TV' have.
But I don't mind at all if regular people use it to test 3D TV's in the store.
You don't need a camera to see the errors, you don't need to wear the glasses that 3D TV's use. Just put the pattern into the TV from a USB stick and watch the entire 30 seconds and look for any errors I told you about.
If the pattern is a square as it moves there is no crosstalk, if it's too fast to see then use the dslr camera method pattern 2 uses.

sorry about that.
but i got it done, here's two files: mpeg2 and ps3 mpeg4
edit

the only question i have now is how do i load the ps3 one onto a disk?
do i just burn it to dvd, or is there some arcane method that aludes me at present?

and neuron2,
feel free to host these files at doom9 for testing purposes.

edit,

here's a comparison showing cyberlink powerdvd ultra 7.3, using ati2600xt and dxva, against ffdshow lanczos 6 taps resizing only.

Use search to learn how to author to PS3. There are a lot of threads about it.

i'm going to make another pattern, i don't really like this one.

when i'm done, i'm going to upload a mpeg2 to here and ask that somebody dl it and upload a burnable file that once burned to disk can be read by dvd players.

i tried those links and they just lead me down the garden path to 31 page threads.
and they talk in half speak to my ears, i don't get a lot of what they're up to, so i ask can you help me out?

good stuff. i'll be back!

If you just need a standard DVD, then author it with Muxman, or TMPGe DVD Author, or...

650 posts and you don't know how to author a simple DVD?

If you are going to make an MPEG2 be sure to make it DVD compliant.

What are you trying to accomplish? There are excellent test patterns available.

"not every fish knows how to fly" - me

here's the avi,
edit

edit, here's the mp4,
edit

please just make it and upload it. i'm really lost to this whole eal of making avi's playable in dvd machines.
after in leisure maybe i will read those 30 page threads and learn a lot.
but for now i'm asking you to do it for me and upload a buranble file that can be read in a regular dvd machine once on the disk.

pretty please

edit,

well, i got it to go.
but now the aspect ratio is all wonky since i set the pattern to 720, 480.
so now i have to redo the pattern at 640 480.
oh well.
at least i finally got it going.
anyway, thank you neuron2, i will post the final product later on. in a few hours time.

well i got the dvd made, and technically it works, but it's so softened in the process it makes it worthless to me.
here's the avi's. i maade one pal and one ntsc: edit
ffdshow doesn't resize them, in order to use ffdshow effectively on them you need to try the next set of files i'll upload, the mp4's: edit

this test pattern i made is used to show the effectivness of different resize methods,
so if the pattern edges are all smothed out, then all the resizing looks the same!
do you get what i'm trying to say here?

so far i tried to make a new ts and add the vob i made before, tried two different ts muxers to do this, with no luck.
then tried the tmpge dvd maker neuron2 mentioned, and it just squashed out any detail in the resize pattern.
then with joy i tried setarips dvd maker thinking it work work, but the burned dvd had a pattern with wavey lines all over it, usless to me.

may i ask for somebody to make a lossless version of the avi;'s i just uploaded, and share them with me in a dl'able file? please.
pal and ntsc, like the avi's are one ntsc one pal.

DVDs are not lossless, since MPEG-2 video encoding is not lossless.

If the test pattern is 720x480 or 704x480 or 720x576 or 704x576 then at least it can go onto a DVD without resizing. If it is a still image, there should be little loss at high bitrate, but it's not lossless.

Cheers,
David.

I made a version of the NTSC one for you. There is an ISO as well as the DVD project directory. You can open the VOB in DGIndex to see that the lines are fine. When you play it in a player, make sure deinterlacing is off, as that may produce aliasing (what you call "waviness").

You had a serious issue in your process. Your background is colored, so when you convert to YV12, you will smear out the lines due to the chroma averaging. So I made the background gray to preserve the lines (there's no luma subsampling). Second, I added borders to get the standard 720x480 for NTSC DVD.

I encoded it in HCEnc and authored it in TMPGEnc DVD Author 1.5.

720x480, that's 1:33:1 aspect i'm guessing.
the pal version would be 720x576.

as you can see here, that's not a option in tmpgenc dvd author:


i already tried to make one 720x480 and couldn't do it, so doing one 720x576 will prove futile too.

so, may i humbly ask you, neuron2. to please make one in pal resolution too.
or if i shared the ntsc version with pal users to test would it work for them and we wouldn't need a pal version?

Are you making a DVD compliant MPEG2 file using HCEnc or are you opening an AVI in DVD Author?

in a movie (ghost in the shell innocence), the scaling is better on the ffdshow media player classic than it is on the ps3.
but on the test disk the ps3 looks perfect.
i'm wondering if the result on the ps3 is being deinterlaced?
because to my eye it's obvious the result is being messed up by ps3 processing.
i tried various things in the ps3 menu setup to get a true result but i couldn't do it.
the ntsc works fine on powerdvd and media player classic though.
i tested the file you made and it's progressive, so the ps3 shouldn't be deinterlacing it, right?

edit,

come to think of it. the mpc and ffdshow isn't using pulldown, which would blur the picture. remember i talked to you about that before?
so i wonder if the ps3 is using pulldown on the test disk, changing the result from mpc which isn't using pulldown.
dgindex says the disk is 29.976 fps, so that means pulldown flags are there, which the ps3 might honor thus bluring the result.

There's no need to deinterlace it, but I have no idea what the PS3 is doing.

Sorry, no, I'm a geezer.

No, there is no pulldown. The NTSC one is encoded at a frame rate of 29.97 progressive (NOT 23.976 with soft pulldown).

scaling test disks. 16:9 4:3. can somebody test the 16:9 to see if it's made right?

Quote:
edit

a word of warning.
this disk only works if your dvd player plays 16:9 dvd's in 16:9.
i say this because the free dvd player media player classic does not,
it plays 4:3 natively.

basically, this test disk only works on dvd players that upscale to 16:9.
if your dvd player does not upscale 16:9 aspect ratio,
then do not take this test.

basically, this test is to compare the playstation 3 vs htpc upscaling dvd players such as powerdvd and ffdshow.

on that not, if you test ffdshow with this, the resize needs to be a 16:9 aspect ratio, else the result will be wrong.

i made the test for mainly 1080p ps3.

edit

i included a picture in the 2 folders to show how to burn the right folders.

this is a pattern to show how efficient the scaling on your dvd player is.
look at the diagonal lines and look for artifacts like halos or a ripple combing coating the lines. that coating ripple is poor scaling. the halos show oversharpening, or poor scaling.

the test pattern doesn't seem to work on the ps3.

i just played the test disk on the ps3 then the htpc and the aspect ratio is different from the htpc and the ps3, which explains why the ps3 results are so wonky.

i literally got a piece of paper. put it againt the inside edge of the tv on the screen in the corner, and marked with a sharpie where the test pattern began.
the ps3 is way different shape than whats seen on the htpc.

The NTSC 16:9 4:3 disks are encoded at a frame rate of 29.97 progressive (NOT 23.976 with soft pulldown).
The Pal 16:9 4:3 are encoded at a frame rate of 25.00 progressive.

the ps3 cannot play ntsc 1:33:1 aspect ratio in proper correct ratio, so the ps3 can't do the 4:3 test.
the requirement to play the test is the player be able to correctly play a 1:33:1 aspect ratio pattern.

to test media player classic, use the 4:3 test.
to test the ps3, use the 16:9 test.
that's what i'm saying, but i ask you a question now.

i made the 16:9 disks yesterday. can somebody who knows encoding and stuff like that look at the 16:9 disks and see if they were made correctly or not?
i ask because you kind people are the authority to me when it comes to avisynth and encoding, so i humbly ask this of you kind people.
