My current job is wondering if a de-interlace or other filter will improve an AVI captured from a television and subsequently made into an ISO. It's an oldie from circa 1987 in whatever the technology of VHS was then and just apparently recorded to tape and probably on the slow setting.
The sound is pretty good for audibility. But one of the intertitles looks like it could have been from the "Marge and Jeff" program in 1955.
My point is the image could be sharper and less wavy and perhaps a de-interlace or other filter in Handbrake or some other tool could improve it. There are two files about an hour or so each. I am ignorant of filtering so please be specific and avoid shorthand. AVI Synth may be the answer but I have scant knowledge of it.
I'll run Media Info to see what the resolution is:
656*496.
There's some hiss on the audio and I have Goldwave for that. Best would be to unpack the original ISO again and restart the job. I'll go back and look at my thread for that.

How long should the clip be? Even editing is a job I am not good at.
I found this thread which has a lot in it but even there it says each job is unique and requires experiment:
http://forum.doom9.org/showthread.php?t=156028
I've looked at one of the data descriptions for my job and the original is 720x480. (I had previously run some compression on it to get the large file size down. )
At this point I have the TS file set from the original job. In order to make a short clip where should I begin? Which program to load the file set into and recode?
It was also noted that de-interlace may not be the answer at all, but just a term I thought applied to VHS to file conversion/filtering. -
I don't think deinterlacing is what you need but until I've seen a clip there's no way to know for sure. If you VIDEO_TS file set, ie VOB files, use DgIndex to extract a sample. Mark in, mark out, then File -> Save Project And Demux Video. Upload the M2V it creates. About 10 seconds with moderate motion is good.
-
Haven't used DGindex much except for what it loads into Virtual dub.
My reply for this won't be instantaneous. But there's time to play around with this. -
Progress. I have the full m2v file to work with which was fairly simple once I located the
commands in DGIntex downloaded at Videohelp.
Can you give a screen shot for the mark in and mark out job? I don't see those commands in DGIndex or will I be loading Virtual Dub (one program I've used) ? -
Mark-in is the button labeled with a left square bracket. Mark-out is right square bracket.
-
Yes, still DGIndex. Just scroll to a place with steady movement and mark-in ( [ ). Scroll a little way more and mark-out ( ] ). File->Save Project and Demux Video. Play it to make sure you didn't save too much (10 seconds will be plenty). Upload the resulting M2V.
DGIndex is a basic tool when working with DVDs and AVISynth. Learn it. You might even read the included docs since the creator of the DGMPGDec package is also the best doc writer in the business. -
You folks do realize that you may be dealing with some crushed Divx/Xvid file right?
Just checking. -
Thanks manono. There's a place on this with a figure using a floor broom slowly. That should be what you want.
-
On the documents, yes I'd like to print for the future and read those. Especially if they are as you say well written and understandable.

I am back and have what I think is an 8 second clip. I used a different portion which shows color and white in stage lighting.
No progress though since my d2v was rejected by the uploader section of the program.
Wrong file type.
I made the clip. Saved it. And that was all I did before attempting to post it.
No wavy lines as such in this, it just lacks sharpness without calling it grainy.
And yes It was likely made with old style VHS gear and put in DVD Format. -
Checking the clip showed that it does not play in VLC media player. Something is wrong with
my file/filetype save operation.
I previewed the clip in DGindex. From there what should the save sequence be-- in steps if you don't mind. Or can I simply reload what is labelled as d2v in Win7 properties and recode it properly?
The file is moved to my desktop so I can find it without too much problem. -
-
A rhetorical question then.
I was unclear that this would be a new project and not a reload of what was in there. -
The D2V file is just a text file with the index of frames. It is used by Mpeg2Source() in an AviSynth script to quickly locate frames for decompresssion. You can open the D2V file with Notepad and read it:
Code:DGIndexProjectFile16 1 Algiers_snippet.mpg Stream_Type=1 MPEG_Type=2 iDCT_Algorithm=6 YUVRGB_Scale=1 Luminance_Filter=0,0 Clipping=0,0,0,0 Aspect_Ratio=4:3 Picture_Size=720x480 Field_Operation=0 Frame_Rate=29970 (30000/1001) Location=0,0,0,1162a d00 5 0 0 0 0 0 b0 b0 90 b0 b0 a0 b0 b0 a0 b0 b0 a0 900 5 0 202752 0 0 0 30 30 90 b0 b0 a0 b0 b0 a0 b0 b0 a0 b0 b0 a0 900 5 0 446464 0 0 0 30 30 90 b0 b0 a0 b0 b0 a0 b0 b0 a0 b0 b0 a0 900 5 0 696320 0 0 0 30 30 90 b0 b0 a0 b0 b0 a0 b0 b0 a0 b0 b0 a0 900 5 0 991232 0 0 0 30 30 90 b0 b0 a0 b0 b0 a0 b0 b0 a0 b0 b0 a0

I'm back to give it another whirl. The length should be as specified. The clip shows whites and skin tone plus some color in good light. There's a lot of variations in the stage lighting throughout the piece.

Why is the thread title "Use de-interlace or other filter to improve VHS capture AVI" when it's already been deinterlaced and is progressive?
Anyway, every fifth frame is a duplicate of the one before. The dupe frames can be easily removed. The much bigger problem is that in every five-frame cycle, in addition to there being a duplicate frame there's also a missing frame. It can be replaced using interpolation techniques, I suppose, but it's nothing I'd want to teach you.
I'd suggest you 'fugeddaboutit'. -
That video is encoded interlaced but the frames are progressive. It was once VHS tape and has been filtered badly. It was deinterlaced but not decimated so there is a duplicate frame every 5th frame. Too much noise reduction was applied. The bitrate was way too low for the source material. I don't know what you mean by "wavy". You can make minor improvements with QTGMC(InputType=1) and some other sharpening but it's probably going to over processed.
Code:Mpeg2Source("D:\Downloads\COETest3.demuxed.d2v", CPU2="xxxxxx", Info=3) TDecimate() # remove duplicate frames ColorYUV(gain_y=20, off_y=-2) # a little brighter Dehalo_alpha(rx=5, ry=1) # remove VHS oversharpening halos Spline36Resize(width/2, height) # half width QTGMC(InputType=1) # edge cleanup MergeChroma(last, aWarpSharp(depth=20)) # sharpen chroma Sharpen(0.3, 0.0) # sharpen horizontally TurnRight() nnedi3(dh=true) # restore frame width TurnLeft() ChromaShift(c=-2) # shift chroma left 2 pixels
-
The consensus is leave it alone so that's what I'll do. Not a job for a neophyte.
