DVD to Film Transfer questions.

[Oalboukharey]

Hi, i know u might not have heard of this, but there is such thing to transfer any digital media (i.e. DVD) to Film Negatives that is used for playing in Cinemas and so on.

the thing is, they cost alot i assume and that i am fro the UK.

there is a company in the US called LaserGraphics, which they sell the equipment to do Film Recording.

http://www.lasergraphics.com

Now if you read the features and specs, they mention that when digital media is transfered on Film, Low-resolution images (e.g. video) automatically up-sampled in real-time while recording to eliminate video raster lines, with No pre-scaling required.

now that interests me, because i have read other reviews about this stuff, and its been said that you can hard tell me if the transfered image actually came from a VHS tape!

so im assuming that it kinda boots up the quality and the resizing of the image wont be done by pixels but by raster (lines) on the image.

Go and read it up, click Producer 2 and read on. now there is another company which is in the UK called RPS Film Imaging Ltd.

Now, i assume that they do the same thing, but they dont give much details, but i do think that the same thing applys to them when they transfer digital media to film as LaserGraphics do.

All i ask is your opinion and can someone here tell me anything about this.

i would really appreciate it if anyone can.

Thanks very much.

anyone?

[General Plot]

Heh, you bumped this thread after only 2 hours, expecting an answer already. That seems a tad impatient.

[Oalboukharey]

well, i was sick this morning, but i still had to go to school, so i was kinda expecting an answer. sorry about that.

it seems that u didnt bother answering anything?

[Oalboukharey]

i guess not. hmp!

i also forgot to mention, that if u have a digital media that has a low bitrate, would that have any effect on when it is getting transfered on to Film?

[XxCrashxX]

sigh
You cant improve the quality of low bitrate digital video or vhs or whatever
you can pass it through some filters in order to sharpen the image or blur it some, and yes you can increase the resolution, but that is all. There is no way to make a vhs source look like dvd quality video.

[Razor Blade]

Why don't you just use ffdshow to upconvert the vdeo to an HD res with blur/sharpen filters to increase image quality. Here are some examples.



Now of course you'll need a decent computer to handle this and then hook it up to your hdtv or monitor. Or you could always buy an upscaling dvd player.

[Oalboukharey]

ummmmm. wat was the difference there?

i want to show u an image, but i dont know if u can attach here.

[D.D.]

its a lot sharper in his cloth textures ! impressive considering you can't "upgrade" quality that isnt there

[Oalboukharey]

well, how do u upload a pic here?

and, the image is from a laserdisc! recorded to a DVD, at SP mode, so the bitrate is abit low, so i wouldnt know if thats the actual quality of the LD, at least if it were recorded at HQ mode, i will be satisfied that its recorded at a quality where there wouldnt be any second thoughts.

[D.D.]

sorry to say but i recently watched a laserdisc on my parents' new tv and the image quality was just really really bad. probably because the codec was really really primitive (before mpeg?). i doubt anything will help it much (based on what i saw of the bee gees concert on LD -.- ). it made my dad sad because he still believed in the quality of LD i was very shocked as well because it was very obvious where the compression artifacts were. good luck getting higher quality though and if you find out anything please tell us

if you want to upload an image here, just go to advanced reply and click on attachments. however, what RazorBlade did was upload it elsewhere (ie. imageshack) and link the image by using the little picture button in the reply box.

[Oalboukharey]

okay, here are some pictures here.

they are low bitrate, or just bad LD quality.

because the image gets resized or upsized (i dont think by pixels, but raster if thats true or possible), the bitrate wouldnt matter at all.

Can someone tell me about this?

[Oalboukharey]

ummmmm. i posted these pics here for you lot to witness.

i dont know if anyone owns the film on LD, but i also wanted to know if that the actual quality? or it could be better because it is recorded on SP mode (4500KBS).

[D.D.]

i dont own the films i think that is the actual quality of LD at its finest already. they are rather small, but any bigger and i think artifacts due to LD's compression will show. im currently on campus so i cant tell you if this is for sure the case, but SP mode DVD is probably already much better than LD.

[Oalboukharey]

i know that, but recording the LD in that mode will proberly show the artifacts on the DVD, but i wouldnt know. i cant get in contact with the person, as i think he is upset with me becuse of something.

As for those who dont know wat this is, this is the rare Japanese version of Jackie Chan's Police Story. it is out of stock and print. very rare indeed.

[Razor Blade]

So you probably can't buy it again huh, and that's why you want to do this Gotcha. Well you may be able to find it on ebay nevertheless, possibly on DVD? If not like me and D.D. said before you can't really get much better quality than that. You could re-encode it and maybe sharpen it up a bit, fix colors etc. But that's about it. As for the whole LaserGraphics deal, is it really worth it? Just the sound of it sounds like it's gonna run you a lot of money.

[Oalboukharey]

i wouldnt mind really.

and to think it is that easy to find this????? NO! this is extremely rare! trust me...i have done my homework for 2 years, and i am lucky enough to find someone who had a copy and was willing to do this for me.

And please! didnt anyone answer my question??? it was about the resizing of the image, rastering up or something like that? lines upsizing to be more clear i think. is that wat will happen wen u get LaserGraphics to do the job?

[Coolsvilleman]

What you want this to do isn't possible (make lossy into loseless). It's not possible to upscale a normal t.v. D.V.D. signal to get H.D. whatever. As the saying goes "You can't get something from nothing.". That being said it is possible to estimate what data should go be inserted into the missing locations to make a pseudo-H.D. like quality but impossible to make a true H.D. quality from a low definition source.

[Oalboukharey]

yeah. i seem to know that. but wat i want to know is, because resizing an image can have an image loose quality when done by pixels, but correct me if im wrong, LaserGrpahics 'raster up' their resolution of a video image.

now from people who dont know, raster is lines, unlike pixels they are dots on a paper. and because it is raster, the bitrate of the video really wouldnt show right?

Please someone tell me, if i am correct with that method? and also if this is wat LaserGraphics does? as in raster up the image.

Anyone?

[Oalboukharey]

ummmmm.

Anyone?
