Today I made my second blood donation - done first four years ago...

Why I have waited so much from the first one - and why I did not make the first before - frankly I don't know... it is a quick, almost painless procedure, but it could save a life, so I decided to make it more frequently - as much as I can.

Please, donate blood, it's very important!

Thanks!

So, I'm making a custom BD of a film (Fate/Stay Night Heaven's Feel 1. presage flower), and using different sources. The video is the IT BD from Dynit which has slightly better compression and has less banding than the JP BD. However, there's no English subtitles. The JP BD has them, and because I know the compressionist in Italy who did it, it has the same timing as the JP BD which makes adding subs for viewing on a PC easy.

However, I prefer to view films off a disc whenever possible. I downloaded the subs of the JP BD, but they're in a file format I'm not familiar with- .SUP

The BD format uses .PGS subtitles, so I was curious- would they need to be converted to make a self-authored disc? And if so, how?

(Also, if I were to do a 1:1 lossless version using the .m2ts file, would I rip it encrypted or unencrypted?)

Sorry for the n00b questions- I've been a PQ snob and finally decided to make custom BDs. (I may be helping out someone do a custom of Suspiria '77, so this would come in handy.)

So as many of you know, the Friday the 13th films on BD features the original mixes in AC3 form and that is only for Part 1-3. 4 and up are remixes and have multiple added/missing sound effects. I do not know exactly all of them but have heard of some from various sources. My plan is to find the best source for the original mixes and from talking to a few people here and other sites... it seems the VHS tapes would be the best bet. The laserdiscs do not feature digital sound or they would be the best option. Part 6-8 on LD does have digital sound but that does not help us with 1-5. I have just purchased brand new and sealed VHS copies of 1-3 and 6-8. I need 4 and 5 to complete the Paramount series but I will get those when available. Now I need all of these VHS copies captured in a lossless format and synced and I'm sure they will bare much better results than the AC3 audio. Any thoughts?

Few days ago, while watching Mortal Engines, I'm pretty sure I've spotted Wen Jiang Baze Malbus from Rogue One):



first shot of the scene in the "balloon city" bar; am I wrong?

Did you ever spot any actor/actress cameo, uncredited - not even by IMDB?

Ok... It's not correctly. I don't even know if it's Polish in "Borat" and why it sounds like "bad Polish" when movie takes place in Kazachstan.  

So I land here coz of workprints and SporV ; (his blog of "master lists") 
Funny: at the end of VHS times I was hunger for wide movie versions but now when realized many of old (4/3 and 16/9) versions were fuller ( than official theatrical cuts) I reversed my mind. 

It is just begin. 

PS - I can hurts english language so treat me softly coz u treat on my dreams... or somethin'  

Witam

Anyone have a better audio source for this teaser trailer?

Don’t need video, just a better audio source, if available. Thanks, guys!

Few days ago I bought a big USB memory (64GB, Kingston) at a great price (6€); was pretty sure that, for that price, it would be surely slow, but hey, it was an USB3, so it *can't* be so slow... well, indeed it WAS SO SLOW, even worst than what I thought... reading max speed is about 20MBPS, while writing max speed is a ridiculous 5MPBS!

Still useful for small files, but dreadful to move big files... so, what could be used for?

Well, download speed is around few MBPS, so I thought to use it as download "cache" - indeed, my download speed is just around 5MBPS (a coincidence?!?); put the files on it, instead let an external HDD connected the whole night - that will consume more, and wear quite a bit; you could always play the files from there, and, if the bitrate is higher than USB memory speed, then copy the files on the HDD when needed. Sure, 64GB is not that big, yet is not that small as well, so if it happens you have a decent size slow USB memory hanging around because it's slooow, this could be a useful tip (I hope)!

Working on The Shining lately, I had been pointed out by a collector that there are some of Kubrick's latest films with wrong color grading on BD.

So, the list is this:

2001: A Space Odyssey - ?
A Clockwork Orange - ?
Barry Lyndon - 1999 DVD
The Shining - open matte DVD
Full Metal Jacket - 1999 DVD
Eyes Wide Shut - ?

near the title I'll put what source *may* have the right color grading - or at least, the more pleasant or the lesser of the evil.

Probably (apart The Shining, that it's under testing) I'd regrade them - as usual, not a promise!

Waiting for your help!

This is just something I noticed to be a problem with my own captures of analogue sources. For example if you capture an interlaced VHS tape to a DVD, then you are losing important information.

The reason is simple; DVDs always have a color sampling of 4:2:0. As you all know, this means that for every 4 pixels, only one pixel of color information is saved.

Now, the way interlaced material is saved digitally is with alternating lines.

Line 1: Frame 1, Line 1
Line 2 : Frame 2, Line 1
Line 3: Frame 1, Line 2
Line 4: Frame 2, Line 2
Line 5: Frame 1, Line 1
Line 6: Frame 2, Line 2

And so on.

You can probably already see the problem. For every second frame, you are losing the complete color information!

This means that if you deinterlace your video back to 50/60fps, then you have no color information for every second frame. A simple deinterlaced will simply copy the color information of the odd frames to the even frames, thus creating weird looking frames like this:




On the left side the erroneous frame with the color information taken from the previous frame, on the right side the frame as it should actually look. (This example here is made in Photoshop from a normal video, but it pretty accurately represents the artifacts you will get when you do this).

There are some deinterlacers that will temporally interpolate the color channel for this reason afaik, but this won't work properly with very fast movement and lead to ugly artifacts nonetheless. That information is permanently lost and effectively, every second frame is only black & white.

This is actually the case with all HDTV broadcasts, which are all saved in 4:2:0. If you use a deinterlacer and framehop through actual HDTV footage with 50 individual interlaced frames (or fields, if you prefer that term), every second frame/field will have the color information of the former frame.

The solution? When capturing an interlaced source, always capture in the very least in 4:2:2:



With 4:2:2, you still have horizontal chroma subsampling, but vertically, you keep the full resolution. This is necessary to preserve full color information in interlaced material.

If you capture an interlaced source to DVD or a PAL miniDV camera, both of which use 4:2:0 color subsampling, you will lose color information of every second field. This especially applies to TV broadcasts with actual 50 frames/fields and most likely all your old VHS/Hi8/Video8 home videos. So, it's better to capture to 4:2:2 or 4:4:4 and if you want to deliver in 4:2:0, it's best to deinterlace first.

Interestingly, NTSC miniDV uses 4:1:1 subsampling which actually preserves separate lines. Though in this case, your horizontal chroma resolution is quartered, so it's doubtful whether that's worth it.

I believe this is particularly important for Laserdisc capturing, which afaik are often (or always?) interlaced. I think you can probably still get the proper frames back if it's just a 24p stream in a 60i stream (telecine), but if it's actual 60fps content, you are losing all the color of half the frames. Which may apply to any kind of live recordings, interviews, behind the scenes footage, and also some company logos/trailers/intros and such, which are often not produced in 24p.

Thoughts?
