Conversion 4:3 to 16:9

[jagabo]

The think the border artifacts are a result of oversharpening, not mpeg compression. Try something like this:

Mpeg2Source("HORSE(01).d2v", CPU2="ooooxx", Info=3) 

# IVTC first
TFM(d2v="C:\Users\John\Desktop\HORSE(01).d2v") 
TDecimate() 

# restore black borders that were remove before, so dehaloing will work at the edges of the frame
AddBorders(8,8,8,8)

# overlay a dehaloed video only at sharpest edges
emask = mt_edge(mode="prewitt", thy1=150, thy2=150).mt_expand().Blur(1.5).Blur(1.5)
dh = dehalo_alpha(rx=2.0, ry=2.0, DarkStr=1.5, BrightStr=1.5)
Overlay(last, dh, mask=emask)

# sharpen a little, skip this if you don't like it
Sharpen(0.3, 0.2)

#remove the borders we added and the letterboxing
Crop(10,52,-10,-56)

# increase contrast and saturaton a little, convert to rec.709, temporal denoise and sharpen/shift chroma
ColorYUV(gain_y=30, off_y=-10, cont_u=30, cont_v=30)
ColorMatrix(mode="rec.601->rec.709") 
SMDegrain(tr=1, thsad=100, prefilter=4)
MergeChroma(last, aWarpSharp2(depth=10).ChromaShiftSP(x=-0.5, y=-0.5))

# upscale
nnedi3_rpow2(4, cshift="Spline36Resize", fwidth=1920, fheight=1164).aWarpSharp(depth=3).Sharpen(0.2)

# just the same portion that Sharc uploaded
Trim(0, 1396)

The dehaloing is effective, but I think you attached my file of post#89 instead of yours, right?

[jagabo]

I think you attached my file of post#89 instead of yours, right?

You're right. I'll fix it now.

[cholla]

First jagabo I want to thank you for all the work.
What you did is above my knowledge level to do.
I have never used dehalo or overlay.
I would sure need to use your sharp edge settings.
I would have to Google to try to understand them.

My BD player would not play the resolution height.
My TV could play it direct.I could see the vertical line but it was only about 1/16th" wide.

Sharcs video you made it from has the line about 1/8th wide.
For some reason in Sharc's video the line is more translucent.

I will explain this again.The line is translucent on all the videos posted here.
I have to be very close to the TV to see it.
From normal watching distance I do not see it
The test pattern Sharc posted does not have the line.
I have tested other videos I have & a few DVDs .
On some the line is there & some it is not.
So I believe it is the TV.


Instead of restoring the black borders;why not start with the original rip from the DVD?
Then use the other procedures you recommend.

[jagabo]

Because the dehalo filter needs the black border to recognize the halo at the edge of the frame. Without it the halo isn't detected correctly.

[Sharc]

My BD player would not play the resolution height.

Many/most BD players won't play >1080 height and/or level L5.
You can try to crop jagabo's file vertically by 84 pixels to make it 1920x1080 (16:9), and you may have to change the Level to 4.1 to make your BD player happy. The PAR (pixel aspect ratio) will be ok, means the objects in the picture are not stretched by the cropping.

Or upscale to 1782x1080 instead of 1920x1164.

@jagabo,
I meant using the DVD rip strait from the DVD.
I uploaded a clip like this in post#35.
It is a pillared & bared 4:3 resolution.
I never was able to determine if it actually had pillars or was just a size that looks like it has them.

@ Sharc,

Many/most BD players won't play >1080 height and/or level L5.

I believe you meant 1164 height like jagabo's video.

My TV played it fine & I believe that was good enough to check the results.

[Sharc]

@ Sharc,

I believe you meant 1164 height like jagabo's video.

">1080" in words means "larger than 1080". So yes, most BD-players will not play files with 1164 height, because 1164 is larger than 1080.
(Your TV is not a BD-player. Obviously it can play .mkv and .mp4 files which are not BD-compliant, and apply its own resizing rules.)

Hi... Your panoramic conversion is one of the option of Atomic Stretch a free plugin for Adobe Premiere, that can give you various stretching options.

I use another method of stretching, a mixed method. I stretch the 4:3 to 5:3 and I zoom the rest to 16:9. With this method some of the upper and lower parts of the video are cutted, but each movie I have seen does not have so many important detail in these two little parts cutted. With these method, The peoples on the video are not too much stretched.

I did some conversions:
The first gave an "Incorrect Resolution" Then "Cannot play this file" HORSE_jagabo_High4.mkv
Correct on this one the BD player could not play 1164 height.

The second gave "Cannot play this file" HORSE_jagabo_1080.mkv
Correct on this one the BD player could not play High 5 even if the resolution is 1080.

The third is a working video with 1080 & High 4.1.
It plays correctly.

@chollo: No surprise, no miracle. It's what I said.
Some players may be even more picky with what they play. Read the specs of your BD player.

(Btw. the 3rd got horizontally stretched again by ~7% ("fat people") by your re-encoding. You should have cropped it vertically to keep the proportions intact, as discussed before.)

Sharcs video you made it from has the line about 1/8th wide.
For some reason in Sharc's video the line is more translucent.

Note that Sharc removed the artifacts by cropping them away. I removed them by dehaloing -- leaving more of the original picture.

I will explain this again.The line is translucent on all the videos posted here.
I have to be very close to the TV to see it.

So I believe it is the TV.

Make sure your TV's Sharpen filter is disabled or lowered as far as possible. All those enhancement filters do is mess up a good picture.

Read the specs of your BD player.

I will if i can find them.

(Btw. the 3rd got horizontally stretched again by ~7% ("fat people") by your re-encoding. You should have cropped it vertically to keep the proportions intact, as discussed before.)

I wasn't co0ncerned about the ("fat people") I was just making an example that would play on my BD player & probably other peoples.
In case someone reads this topic & needs to check out their BD player.

Make sure your TV's Sharpen filter is disabled or lowered as far as possible. All those enhancement filters do is mess up a good picture.

I will check my TV settings to see. It has a lot of settings .

This is my final video for this project.
If the people are stretched horizontally "fat" I will live with it.
I'm now converting it back to a DVD format & will burn that to a DVD disc.
To me it will still be a lot better than watching a small square or rectangle surrounded by black on all sides.
I look at it like this: even if at a movie theater the people are in the correct proportion.
They are still a lot fatter than on my TV.

All the work of the last 4 pages has been spoiled by that stretching. A pity.

All the work of the last 4 pages has been spoiled by that stretching. A pity.

I do appreciate the effort & I'm satisfied with my result.
So I wouldn't say spoiled.

I did a comparison & all the videos were stretched some.
I made these measurements with VLC player & a ruler on a 24" monitor set to 1920x1080.
The original DVD rip 720x480 Man in middle 1 is 3 1/4" at shoulders. Man 2 in white coat is 2 5/16" at shoulders.

jagabo's was the least stretched the resolution was 1920x1164.


HORSE(01) 880x540 6k.mp4 Man width 4"but this video is not 1920 x1080.
