Avisynth:
Code:
AVISource("d:\UnprocessedHuff.avi")The dropout/tracking fix must wait until later. It's slow and unstable. If you have the newest Skylake CPU, I can look to add it. If not, don't bother, it will crash. This is clearly some sort of nth gen madness going on. I'd need to see the whole tape to know what's going on. It cold be reuse, bad analog editing, etc. There's to many variables without physically seeing the tape, or at least the full video. And no, I really don't want to see the whole video, please don't try to upload it. Post the link of the download page where you're trying to download the filter pack. ;) BTW, my video system is busy right now, can't really do anything else. I did the above test clip between tasks. CNR is the name of an Avisynth filter. @msgohan: The chroma leaking across frames is there, yes, slightly. Like I said, proof of concept, it still needs some tweaking. Having 2-3 frames of chroma blend is going to be the best you can do here. CNR was set to wide mode, and that is probably why. |
I've never even heard of a Skylake CPU.
By way of providing data points: the reason I capped on my Panasonic rather than my Philips is I had really bad tearing on the latter. The chroma shift was also significantly worse. What would physically seeing the tape tell you? Filter pack is attached to the last post here: http://www.digitalfaq.com/forum/news...-avisynth.html |

Here is a copy of the download link (left-click on the link): http://www.digitalfaq.com/forum/atta...isynth-plugins Download the RAR to a separate folder, not to the Avisynth plugin folder. If you get an error message, what does it say? |
It was just failing in the web browser. That link worked though.
lordsmurf, could you clarify the HuffYUV vs Lagarith and HuffYUV installation thing? |
I use Lagarith for many of my working files saved as YV12, which huffyuv doesn't support. I don't use Premiere. But I've had no problem with huffyuv in Adobe AfterEffects. That's Adobe for you.

VDub gives an error regarding Camcorder Color Denoiser 1.7 when I try to load the VCF file: no such filter loaded. The one in my filter chain is a Camcorder color denoise 1.6. Am I using an older version of the same filter, or are they different things?
|
newest ccd here (left click): http://www.infognition.com/cgi/getfilter?id=220
Not very effective in this case, however. Best to work in the original YUV before trying RGB. Many more VDub filters here: http://www.infognition.com/VirtualDubFilters/ But watch out for the VirtualDub Filter Pack on this page. Many in the pack aren't updated. |

lordsmurf, I assume CNR is CNR2? You didn't give that in your AVS script, but you mentioned it when describing your workflow.
Attached HuffYUV samples from the pre-game intro video, the game itself, and a studio segment. EDIT: Installed that plugin, still getting the error. EDIT 2: It helps to put things in the right folder. Can now load the VCF. EDIT 3: Can't see the issue pointed out by msgohan, but on the Intro clip the red jacket on the guy who does a layup just before the titles come up sticks around way too long. Unchecking 'wide' under V on CNR in VirtualDub helps but doesn't completely eliminate the issue, removing CNR from the filter chain completely does. |

Thanks for the samples. Apparanetly processed previously by a couple of dudes who spent days in a closed room with their hookah pipes loaded with crystal meth, conducting their own video Demolition Derby. What a shame. Well, we can give a try later. But the vids are pretty well borked. AMybe the default settings for your capture device aren't optimum, but I wouldn't know what to set for. Try saturation for beginners. |
I was a little too quick on my conclusions about that red jacket; it was visible a little even in the AVS file. So I dropped un and vn in CNR2 to 35 from the default 47, and it disappeared. Re-enabling CNR in VDub brings it back though. I'm not sure how to fiddle with those settings, other than checking and unchecking 'wide'. There's an explanation of the X and Y axes in the settings for it, but I don't understand what they mean.
What leads you to the conclusion that it's been processed? |

What you can do is load the other filter (Chroma Noise Reduction) by itself using the revised .vcf file attached below. Then load two copies of your own CCD filter. Set one CCD filter for a strength of 50, set the other for a strength of 30. You can chain multiple copies of the same VDUb filters together.
A .vcf file is a plain text file. You can open it with Notepad to see what it's doing. You can make changes, but NEVER overwrite the original. Save the changes as a new .vcf with a different name. Quote:

Did you miss my earlier edit? I was putting the plugin into the wrong folder because sometimes I'm an idiot.
What would capturing with lower saturation do that lowering saturation in software won't? What's actually wrong with the saturation? |

A bad VCR and unsuitable storage conditions seem more likely than processing.
I mean, yes, it looks awful. I know enough to be able to tell that (as do people with far less knowledge and experience than me, probably). It's the conclusion that it was processed that I don't really understand. I just looked at it and figured that's what a crappy 80s tape looks like. Apart from the horribly red ground-level cameras, which I'm guessing is an issue with the camera settings and nothing to do with the tape at all. Going through in Premiere and cutting it up to use a different AVI for each angle has been tremendous fun, particularly when they add replay wipes. *sigh* Quote:

Skylake aka i7-6700K: https://www.amazon.com/Intel-Unlocke.../dp/B012M8LXQW
Also: http://www.newegg.com/Product/Produc...82E16819117559 Still the current CPU, 1 year later! It really is that good. :) I see the Avisynth post: http://www.digitalfaq.com/forum/news...html#post43574 The name was "lordsmurf's Avisynth". But the forum broke the name. Not sure if it's also screwing up the downloading. So I just deleted it, re-added it as "lordsmurf Avisynth". I've probably added some stuff in the last 6 months. Need to give that thread attention again, new beta download. BTW, that Avisynth guide is being co-developed with the new glossary, as there's much overlap. I always start with my current multiscript, and delete unneeded lines to post it. I must have deleted the CNR2 line? Code:
Cnr2("xoo",4,2,64) # remove chroma banding noise, wide UV settingWide for VirtualDub CNR increases the temporal axis. (I don't use it much, so want to double-check that statement.) Removing it reduces both negative and positive effects. You can play with other value, but I find that the defaults are often best. If those don't do what's needed, no other settings will either. I'm not at my video system now. |

Sorry for the delay. Medical stuff today. Phooey.

I made a trial run with the studio avi to see what could be salvaged from the wreckage. Attached as "A" below. A test, really, because I have no idea what to do with all the pesky horizontal dropouts and comets without destroying what little remains. It's a hassle to keep the scant detail level of the tape from looking like plastic. I lowered midtones and darks to get a little depth into the image, but this might not work if there's dark sports playback during all the talking. Attachment "B" is my feeble attempt at clearing the dropouts with RemoveSpotsMC3. There's some detail loss but IMO you don't get that much back in return. Now need a brilliant idea for those dropouts. And why is that emblem in the upper right so much noisier than the rest of the frame? I had to use two steps (two separate scripts and two intermediate files) to get the "A" results. I can clean up the messy scripts and post later if you want. |

The colors are illegal still, as I only addressed the noise: Attachment 6605 Quote:

Thanks for the notes.
No, there's no detail. So I added noise (AddGrainC). The red jacket in the image tops out at RGB 244, but is mostly around RGB 220-230. The white shirt hits 244. The jacket is still over saturated and looks neon. Unfortunately if red is curt any further the guy's face turns green, then cyan In short, the core image chroma values were wrecked a long time ago. RED is clipped in YUV. More tweaking in RGB obviously due, but you can only go so far with thin data and clipped colors. Are those image from the original? The mp4's have a red jacket under RGB 200 and the shirt collar is white, not cyan. |

Even the AviSynth wiki - which still requires you to actually know what you're looking for to a large degree - is pretty light on explanations for the most part. Quote:
I'm putting together an MP4 of the entire opening sequence, just to give you an idea of how it all works. I'm basically just grabbing the first and last few seconds of each segment, but to catch everything and show the sequence it still needs to be way too long to post as an AVI. There's nothing in it that's not in the already-posted AVI files though. Quote:

I did some quick jobs based on MPG files a while back, and I've noticed that I tended to have the brightness too low and the contrast too high, because I was going in with a nooby 'make the blacks black and the whites white' mindset (and didn't have the color correction or noise removal skills to make almost-white areas less oddly-colored without just blowing them out). I had the opportunity to work with one of those in combination with a DVD produced from the original broadcast tapes, and noticed my versions were also significantly more saturated, so presumably there's a similar issue happening in that respect.

Unrelated edit: For some reason the timezone settings don't seem to work. Apparently I made this post at 8:22pm yesterday, when it was in fact 9:22am. Today, obviously. I have it set correctly in my control panel. MP4 attached. |

In the last 30 days: - Free Member, daily replies, "please I need help now!" - email, (not) potential customer, "I need a phone conversation, and you need to answer these (25+) questions" ... for a $25 project - PM, "can you restore this MP4?", sure, that would be about $65, "I don't want to pay for it!!!!" Some people are f'ing nuts. :screwy: I seriously cannot click this enough: :screwy: :screwy: :screwy: :screwy: :screwy: :screwy: Quote:

Some are actually just "work in progress" with no progress. I plan to address that with my Avisynth documentation. Hopefully I can tap others, like sanlyn and msgohan, to help on it. Quote:
