I could only find it here:

Search for cld2950

I think I also saw it on another site some time ago but I did'nt bookmark it and now I can't find irt again

Anyway, are you going to modify the 2950 for a better composite output?

I have the cld-515 schematics and it seems simple enough to connect a video amp and 75 ohms buffer before or after the TBC circuit, but I guess the 2950 might not have or use the TBC-DAC for the composite at all, but if the DAC is there it could be a simple mod.

I'm willing to be proven wrong, but the three seconds of thought I've given this suggest I'm not.

I don't understand it either but xyzzy mentioned PAL SVCD which I think is 480x576 and maybe that's why it was possible to convert it to 720x480 NTSC DVD by just cropping and adding borders.

So I guess if you captured a PAL source at less than 720 horizontally you could do the same thing but then the scaling would be done by the capture device instead.

This is off topic but since it worked very well on the sample vob, anyway, I used this to remove the line:

ConvertToYV12
turnleft()
descratch(minlen=702,asym=15,mindif=3,maxgap=3,blurlen=8,keep=0,border=0,maxangle=0,modeY=3,mark=false)
turnright()

The good thing is that it should not remove anything shorter than 702 pixels so your starfield is quite safe. I could not get a single detection error in the sample anyway, use mark=true for debug mode.

Now you've mentioned it, I'm going to have to change my script in an attempt to remove them, or they're just gonna bug me every time I see them now...

Sorry, I guess working with old laserdiscs have given me an eye for spots an flaws

It's strange if you have many whole linedrops in your capture, the cld925 is usually very good at filtering them out...

No, I left that in to give the DVD an authentic laserdisc feel...

Well, it was a whole line(s) that missed so I just thought maybe you wanted to remove them, they do not look very movie like.

But I agree that the different spots and line removing filters sometimes remove more than you want...

What displays are you using?

My computermonitor can show 1600x1200, my projector can show 1200x700, I estimate that my pal crt tv can show 640x576.

DVD is 720x576 or 720x480, I estimate the best OT LDs are something like 440x576 or 420x480.

So I guess that my displays (except for maybe my tv) can at least show all the resolution from a LD or todays DVD...

Just trying to squeeze in

Moth3r,

I just looked at the sample vob and it looks very good. IMO the upsampling does not lose much (any) detail because of the already quite low resolution on LDs. I also think that at least all crt users with 16:9 mode will benefit much from anamorphic even if it is STS "faked".

BTW I noticed a linedrop in frame# 1030 in the sample, it's right in the middle of the picture, maybe you already fixed it...

Well, I do keep mentioning 4x3, but there are newer tvs with that mode. I wonder how many people actually bother to use it, though. I know my neighbor doesn't, even after I showed him how much it improves the picture.

On most PAL 4:3 tvs with 16:9 mode the 16:9 setting can automatically be selected for anamorphic dvds if the dvd player is connected via the scart.

Although I don't think this is possible on ntsc tvs/players as the scart connector is a european (PAL?) standard.


PAL = "Pay for Added Luxury"

Film Preservation 1993:A Study of the Current State of American Film Preservation

Quote
Lucasfilm, founded by director George Lucas, has gone to great lengths to preserve film, paper records and artifacts related to its productions.57 To use Star Wars (1977) as an example, Lucasfilm's distributor keeps the usual master cut negative and printing materials in a climate-controlled vault but, in addition, Lucasfilm has retained all other production elements. The firm has built its own archives building to house these materials.


Quote
. To return to the Star Wars example, the Library of Congress has copyrighted release prints and reference videodiscs, but the distributor Twentieth Century Fox holds extensive preprint materials and some circulation copies, and Lucasfilm maintains other production elements.


This was 1993 though...

http://www.smr-archive.com/forum_3b/messages/52.shtml

According to this many newer players with s-video does not have a "real" composite output.

Doesn't the 2950 look somewhat similar to 703/4 but with both pal and ntsc playback of course.

My denon 2300a is a clone of pioneer 515 and according to the schematics for 515 the composite stays composite as long as the sharpness function is off. I think the 925 has the same chassi as 515 and if it uses the same motherboard it could be possible to bypass the whole comb-filter board, but it would certainly be best to first have the 925 schematics.
