What would you do to improve this video?

[sanlyn]

I guess one could suit the bitrate to fit the disc, or suit the bitrate to fit the video. Apparently the original bitrate was set to fit 6 hours on a single-layer disc.

[Caiosouza]

Not if you haven't added the reinterlacing portion of the script. Progressive 50fps isn't DVD compliant and won't author for DVD, no matter how HCEnc handles it. You may wind up with a 25fps DVD that has twice the original length.

But in testing, before this line, and with it her. I got almost the same size in HCenc (Make DVD compliant, interlaced option ON)
Masterfuckingsuckingpixels Batman!
I've filtered out, on VirtualDub
Took around 18 hs, so I'm screwed, not added, # --- re-interlace

If you have DVD compliant M2Vs and audio, then they're ready for Muxman. Aren't you creating any chapters for your DVD?

If so, scroll through the script with it open in VDub and choose frame numbers where you might want them. Create a celltimes.txt for muxman like this:

5000
10000
15000
20000
.
.
.

and put the frame numbers for the chapters inside the celltimes.txt. In Muxman add the chapters in File->Import Chapters (something like that).

If total video frames is: 217.324 for 10min chapter?

15000
30000
45000
........

Right?

...If I open avs code in HCenc like this:

AviSource("drive:\path\to\AVI\filtered.avi")
# --- re-interlace

[jagabo]

...If I open avs code in HCenc like this:

AviSource("drive:\path\to\AVI\filtered.avi")
# --- re-interlace

Anything on the line after the # is a "comment". AviSynth ignores it. They are there for your benefit -- so you know what's going on. You need to include the real re-interlacing commands after that line in the earlier script:

AviSource("drive:\path\to\AVI\filtered.avi")

# AviSynth will pay no attention to this text.
# This text is just here to tell 
# you that the following sequence
# of filters will re-interlace the video.

AssumeTFF().SeparateFields().SelectEvery(4,0,3).Weave()

Myth, I did another test here with the example without this line (# --- re-interlace) and when passing the HCenc he give me a M2V file with the same size on the example of sanlyn, right there behind

(And the result and not 50 fps or twice the size...)

And gives with 25fps. interlaced:

Jagabo, pelo que entendi:

This is a real reinterlace command: AssumeTFF().SeparateFields().SelectEvery(4,0,3).We ave()
And # --- re-interlace is a comment on the above command (in case the code that comes after ...)

Eu retirei so o comentario...então.

Mas porque Manono não me falou isso antes...

Sample:
Correct title then: FILTERED Final-Interlaced-No COMMENT Line on avs script.mpg

For you all ,the biggest challenge was to make me understand, than solving the problems of the video. hauah! Will did the same...

[manono]

But in testing, before this line, and with it her. I got almost the same size in HCenc (Make DVD compliant, interlaced option ON)

The filesize you get has nothing to do with whether or not you've reinterlaced it, but with the bitrate you used. If you use the same bitrate (6500?) for both encodes (reinterlaced and not reinterlaced), you'll get almost the same size.

If total video frames is: 217.324 for 10min chapter?

15000
30000
45000
........
........

Right?

Yes, and make sure the last one is less than the total number of frames (217324) or Muxman won't complete the authoring.

[Caiosouza]

Hello guys again, the result of the filtered video was very good!!!

But When I put it in HCenc (make DVD compliant) in the first run received a file 1h57min (Bit rate 6500 to 8000max) in another passage received a archive with 1h39min.(6500 to 9500Max)

Since the original filtered AVI is 2h24min.

What am I doing wrong?

I tried creating a few chapters in HCenc it did not work.

First at 15.000, last at 210.000 (10min Chap)

If you're playing the M2V (or do they give you an MPV?) output from HCEnc, then ignore it as players don't give the right times when playing those. Do a mux using Muxman , play it as a DVD, and then check the length.

If it's something else then post the complete script you used. An HCEnc setting might play a role, so you might also post its INI file if the length is off after muxing, but I don't think it will be wrong.

I tried creating a few chapters in HCenc it did not work.

I suggested creating them in Muxman, not HCEnc.

First at 15.000, last at 210.000 (10min Chap)

If you used commas and periods, don't. Put them in the format I showed you earlier - numbers only. Before authoring using Muxman it should show you the number of chapters. Also, if something is wrong often the Muxman log (in the root of the 'C' drive) will explai. That's for Muxman. I have no idea in what format HCEnc wants them.

Right, thanks. Now reauthor, this time adding in a Celltimes.txt as described earlier.

And did you get the complete video in that DVD? Nothing missing? Not too short?

[Caiosouza]

Right, thanks. Now reauthor, this time adding in a Celltimes.txt as described earlier.

First at 15000(10 min) last At 210.000 or 217.324? (total is 217.324)



I think I may have been a problem with the chapters in HCenc,
I am encoding in HCenc the third time, but now without chapters
So for the record:
When I demux the video I received a message on DGIndex: "...bla,bla inverted fields" Fix? = YES

And did you get the complete video in that DVD? Nothing missing? Not too short?

I did not understand this

Edit: Oh... I think this log muxman was a test I did ... sorry

[manono]

I did not understand this

Earlier you said when you played the video it was too short.

But When I put it in HCenc (make DVD compliant) in the first run received a file 1h57min (Bit rate 6500 to 8000max) in another passage received a archive with 1h39min.(6500 to 9500Max)

Since the original filtered AVI is 2h24min.

What am I doing wrong?

I was asking if, after making the DVD, you still think it's too short or not complete.

[Caiosouza]

I was asking if, after making the DVD, you still think it's too short or not complete.

But because short 2 times, I decided to encode without chapters in HCenc, to try to resolve

To finally authoring the DVD (with chapters in Muxman Now)

Again:First at 15000(10 min) last At 210.000 or 217.324? (total is 217.324)

The video became fabulously good, as far as possible.
And the more anxious I am to finish...
I find more problems ...


...caused by my stupidity....hahaha

[manono]

Again:First at 15000(10 min) last At 210.000 or 217.324? (total is 217.324)

I'll say it once more, do NOT use commas or periods. Write it as 210000 in the Celltimes.txt. And yes, that's fine unless you want a chapter closer to the end. If so, after 210000, add another one of 217290.

But because short 2 times...

I don't think it was short. Even the one encoded without chapters will show the same length if playing the video in a software player. Ignore that and just go ahead and author with Muxman.

[Caiosouza]

OK, final lap....
I do not used commas or periods.

Thanks ever !!!

[Caiosouza]

Manono...

WORKED !!!!!

As you recommended, I ignored the short time, I put everything on Muxman and made the chapters, and it worked! All right! 2h24min 15 Chapters !!! Works all fine!!!
I'm really impressed with the final result!!!

I don't understand how you fed 720x576p50 video into HcGUI and got 720x576i25 out of it.

I set interlaced, PAL Profile, Make DVD compliant
That was all I shifted.
But look well, the code was this,do not know if it has to do, but I did VirtualDub before, did not play the script straight HCenc
And so I removed the comment # --- re-interlace

Congrats! From now on you'll be teaching others and won't need any more help yourself.

[Caiosouza]

One last question here, the original video is 352x576, if I apply all filter, but it does not resize it to 704x576(Let the TV-DVd Player do it), I would have less loss in any way?The resizing to 704x576 not affect anything?

[manono]

I always resize using NNEDI3 and then sharpen, myself. Up to you. I don't think there's much difference between the two.

[Caiosouza]

I always resize using NNEDI3 and then sharpen, myself. Up to you. I don't think there's much difference between the two.

In this case let's say the NNEDI3 is better than Spline64Resize(width*2, height),But if I use something like this:nnedi3(width*2, height) ,works?

Anyway, would not it better to work all in 352x576 without resize?

I look every detail, because the original video so bad, that any gain gonna be a wealth

"and then sharpen..." and since touched it, what good would code to my video?

[jagabo]

Using a half D1 frame size will let your bitrate go farther when encoding. But the player's upscaling may not be as good as Spline64Resize or nnedi3_rpow2.

You should get sharper colors by moving the second MergeChroma(aWarpSharp2(depth=20)) after the upscale. You'll have to increase the depth argument a bit.

I see difference in a higher bitrate(6500to9500)?

I just did this question as resizing, because in some tests of the original video on TV, I think the e player's upscaling very good

Thanks for this most: "(aWarpSharp2(depth=20)) after the upscale"

Maybe what you put in post behind,work better than Spline64Resize(width*2, height) after all
This:
Sharpen(0.3, 0.0)
nnedi3_rpow2(2, cshift="Spline64Resize", fwidth=width*2, fheight=height)
Sharpen(0.3, 0.0)

[manono]

But if I use something like this:nnedi3(width*2, height) ,works?

I should have been more clear but I was at a different computer and didn't have the exact wording available then. You'd do it, as jagabo said, something like this:

nnedi3_rpow2(rfactor=2,cshift="lanczosresize",fwid th=704,fheight=576)

Or use the Spline64resize, if you wish.

Yes I understand now, the nnedi3_rpow2 doubles the size and lanczosresize and bring back to the desired 704x576

[Oldretiredguy]

I don't know if I'd call this "better" but it's "different". All I did was:

Mpeg2Source("1992 MX 250 Sample.d2v", CPU=6, Info=3)
Trim(2,0)
QTGMC(preset="fast")
McTemporalDenoise(settings="low")
Spline64Resize(width*2, height)

Wow Jagabo, this is a great improvement over the origina. I'd love to have your knowledge to try to make mine better. Just for the sake of question, how long would it take to do what you did to a 2 hour video? That is the time length of the video I have that needs to be "fixed-cleaned up-repaired" or whatever.

I can help you with what little I have learned, the first step,is know what you want to do, what result you want.
For a 2 hours original video: 15 to 20 hours processing with filters, If you have a good PC. But not, twice that long.

Thanks for your kind offer. I have another thread going right now regarding a vhs tape that is very valuable to me that I tried to save to dvd a few years back and it didn't work out very well. I have the original so now I want to try to learn a bit of the video trade. I don't have any fancy equipment just my trusty laptop and a burning desire to learn what to do. You might try jumping to this thread and see where I am at. https://forum.videohelp.com/threads/360511-Vhs-DVD-clarity-question.
