Capturing SD footage from HDV Cassettes

Hello folks.

Sometimes I will use my Canon Vixia HV30 as a VHS archiving device. These archives I like to dump to my computer for long-term storage. However, the programs I use -- HDV Split and WinDV in Windows 10 -- are failing me.

1. HDV Split will capture HD footage, but it craps out when I try to introduce a mini-DV cassette with a standard-def, VHS recording on it.

2. I'd try WinDV, but it craps out on me no matter what I'm trying to capture, even HD footage. (I keep getting the error message, "Can't find DV output pin".)

Is Adobe Premiere a solution for this? I have a Mac running Catalina (as an alternative platform), but that will no longer recognize firewire, even through a thunderbolt adaptor.

Anyway, thanks folks.

Video picture flicker/flashing problem

I am wanting to convert VHS tapes to digital files on (initially) a laptop running win 10. In the past (up to 10 months ago) I made some successful recordings using an August VGB200. Recently when I attempted to convert the tapes, at first all was well. But then I started to get an annoying flickering or flashing of the video image appearing on Arcsoft Showbiz window. This would go away and come back. It would sometimes seem to respond to a change in the settings but then re-occur with the new setting. I have tried Debut software. And have purchased Video-2-pc device all to no avail. I have elliminated the VHS recorder as a possible cause as the symptom still occurs recording direct from the TV. Tim (at Video-2-pc) suggested that some of his customers identified a win10 update as a possible cause and they overcame the problem by rolling back the updates. My questions are:- 1. Can anyone shed some light on what the problem is?. 2. Has anyone had a problem with win10 updates?. 3. Recommendation of a device that definitely works with the latest win 10 updates?.

Item that plays on device does not play in VLC

First post, and not sure where to put it, so putting it here for now.

My stepfather picked up a device (a Victorla VTA-750B) and used it to convert an audio tape for a CD-R. It plays just fine in the Victrola, but VLC 3.0.11 (and my stepmother's Lennox Sound boombox) will not play it. Looking at the disc with File Explorer, the disc looks empty.

removing black frames from interlaced footage without quality loss?

October 5, 2020, 6:55 am

Hi!
I got a VHS rip of an old anime called Serial Experiment Lain. Unfortunately there are some black frames randomly in the video stream every few seconds to minutes. Weirdly enough after a black frame, the interlacing is very visible and goes away again after the next black frame.
https://www.youtube.com/watch?v=sK3y4lO61rc

The original uploader stated "The video is uncompressed, probably to retain every single grain of vhs tape goodness for the sake of authenticity." But it isn't. There are some minimal compression artifacts. Also it's only 4gb over 1.5 hours of footage with 720x480 at 29.97fps per file.
My question would be if it would be possible to remove those black frames possibly without reencoding the whole stream. Is there maybe a program that can remove black frames, replace those with the nearest nonblack and just reencode those bits from the last I-frame to the next and copy everything else from the original stream?

I have tried ffmpeg with the following command:
"ffmpeg -i in.mpg -vf blackframe=0,metadata=select:key=lavfi.blackframe. pblack:value=99:function=less -vsync cfr -c:a copy out.mpg"
It worked wonderfull! Unfortunately the quality loss is very extreme. I would like to keep it very high quality.

After that I tried to include "qtrle -pix_fmt rgb24" to get a lossless file and bother about compressing it later. The only problem, for some reason it looks like it uses chroma subsampling, or some other sort of lossy compression, even though I used rgb24, which should be lossless. This would mean, that it was already there before this process. Checking with MediaInfo revealed, that the original file also has 4:2:0 chroma subsampling. The interlacing would explain, why it is not easy to see. But the ffmpeg version also still has interlacing, but it now reports as "interleaved fields" and I'm not sure how to change that to upper first. As I understand it, that explains the different screenshots. But I also don't know enough to be sure.
https://imgur.com/a/8CaBGlV

Also the finished file was ~150gb and I'm not sure I can get it down again to the ~4gb of the original file without losing too much quality.

This is my first time having anything to do with VHS rips and interlaced video, so please correct me if I am wrong with anything and feel free to reply if you have any suggestions on this topic!

Having trouble with probably an embarrassingly easy FFMpeg routine

Hey guys, it's ya boi Lemon comin' at you with yet another FFMpeg hiccup, slap like and hit that bell

So I have some old DV videos that I'd like to convert with FFMpeg just because I wanna git gud with FFMpeg, no other reason. I could very easily accomplish this in VirtualDub but NO

The source videos are 16:9 DAR 29.97 (59.94) interlaced. I want to convert them to x264 square pixel deinterlaced videos (CRF 20 medium) presumably with yadifx2, and I also want to scale them to 1280x720 because for some reason Youtube treats SD videos like shit.

Can anyone help me map out this command? I feel like I'm having to enter the -vf argument three different times in the same command.

Is there a relatively simple way to remove the first and last chapters of an mkv withour re-encode or remuxing the file?

If there isn't, is there a script someone could point me to that would achieve my desired result?

"Real" untouched Remux of an UHD BluRay: eac3to vs. mkvtoolnix vs. MakeMKV

October 5, 2020, 1:41 pm

Hello guys,

I was wondering how I am doing a real remux of an seamless UHD BluRay. In my example I am trying to backup my Star Wars Episode 9 UHD to my hard disk. I found the right playlist and added the playlist to mkvtoolnix, eac3to and MakeMKV to make a remux of it. Theoretically, every software should create the exact same files, because it is a remux. But every software created partly different files. I demuxed every mkv and every movie file (the HEVC stream) had a minimal different file size. (See the picture I uploaded)

So I was wondering: Does every Software create an untouched Remux? Where do the minimal differences come from? Which software creates the real untouched Remux? Keep in mind: With a not seamless branching UHD, mkvtoolnix and eac3to are creating exact same files. Only with seamless branching the files are different. And MakeMKV creates every time slightly different files.

Colorspace Conversions - YUY2 and YV12

October 5, 2020, 3:37 pm

With regards to SD home videos captured lossless YUY2 with HuffYUV codec with target delivery codec h264/mp4:

If all of my AviSynth filters work in YUY2, should I still be converting to YV12 anyway within my script?

If so, should I still do it at the top of my script? Or as the very last thing I do?

i.e. Is there any benefit in retaining YUY2 as long as possible or better to convert to YV12 early on before all the filters? Is there any speed gain if converting to YV12 before QTGMC? My version of QTGMC accepts YUY2.

Or, should I leave it YUY2 and just add -pix_fmt yuv420p to my ffmpeg batch file script when converting to h264?


2nd Question:

If my target output format is instead ProRes 422, do I just keep it in YUY2 the whole time? I assume if I convert to YV12 in the Avisynth script, I have to convert back in the ffmpeg conversion to ProRes because ProRes is 422, not 420? :confused:

ive been told that AV1 is better then x265 but is this really true? im yet to do any tests

Trouble opening AVS in Virtualdub or Avidemux

Alright, I'm trying to use QTGMC on a VOB source. The VOB has been run through DGIndex. I can't figure out why this isn't opening in either Virtualdub or Avidemux.
Virtualdub reports: "File (the avs) does not have a video stream."
Avidemux reports: "Attempt to open (file) failed!"

I suspect I'm missing something blatantly obvious, but I'm not very familiar with avisynth usage.

Here's the contents of the AVS:

Mpeg2Source("C:\asdfas\VTS_01_2.d2v")
SetMTMode(5, 8)
QTGMC( Preset="Slow", SourceMatch=3, Sharpness=1.0, TR2=0, Lossless=2 )

Handbrake settings for Simpsons DVDs?

OK, so I've been having some trouble getting optimal video quality from my Simpsons DVD rips using Handbrake but I have made progress. I've been able to reduce combing/interlacing by using the "decomb" feature using the "yadif" setting with the preset set to "default" and interlace detection set at "default" as well as setting the "detelecine" option to "default."

However there is still pronounced juttering in panning shots such as the one in this clip https://youtu.be/nu3eidxD2z4 where the camera pans around the boardroom.

My other settings are:

-30fps Framerate set to Constant Framerate
-Encoder Preset set to "very slow"
-Container is MP4 and is web optimized.

Does anyone know of any further settings/tweaks that can get rid of the pesky judder? This is a US NTSC DVD btw.

Thanks!

Color Blending Post Encoding?

Hi again everyone,

My sister has a collection of some old Cartoons I'm helping her to archive. The original Cartoons I tried to de-interlaced looked wrong. So I did some research on previous threads and figured out de-interlacing is not always the proper way to handle Cartoons. After some reading about Inverse Telecine and Srestore, this looked best to me:

Code:
SetFilterMTMODE("QTGMC", 2)
AviSource("E:\BabarRaw.avi")
ConvertToYV16(interlaced=true)
RoboCrop()
ChromaShiftSP(Y=3)
MergeChroma(last, Spline36Resize(width/2, height).aWarpSharp(20).Sharpen(1.0).nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=width, fheight=height))
Levels(45, 1.0, 210, 16, 235, coring=false)
AssumeBFF()
QTGMC(Preset="Slower", EdiThreads=3)
Srestore(25)
Prefetch(3)
Played around in AvsPMod and it looks strange. Like every other frame ghosting the previous. But I think something funky with this Video. When I originally Capture and masked it - there was way too much to black to crop on the left side. I suspect this was actually a NTSC cartoon that was being aired on PAL. So this might be a hint of what's going on. But, I went ahead and encoded that, and noticed strange color blending (Blend.jpg). I can't see this Blend, at least not that harsly in AvsPmod (AvsPmod.png). Is that an encoding problem?

How I stil copy files from old not working Philips DVD R 3595h

Here's a small help from me as I got help from your topics... I got me used Philips DVD Recorder in order to digitize my old VHS and VHS-C tapes. Recorder had non working DVD drive, I found out latter motor for moving head was busted. So I opened it, and as it is plain 3.5" IDE connection for both - DVD R drive and HDD - I connected IDE DVD+R drive from one of my old PCs and it worked flawlessly. Original Philips replacement drive is about 100$ if you can still found one (D5.2 Closed) so it doesn't make any sense. I will try to find a bit shorter PC drive in future, strip off front panel and put it into Philips DVDR.

After fully functional DVD+R drive in it, I connected VCR via SCART and started to digitize tapes, after some experimenting and understanding, I burn DVD+R with videos, finalize it on PC and extract files via DVD Ripper software, recode it into MP4 via HandBrake and voila. PC will read DVD RW (which in my case, all were old and full of errors... ) and DVD+R, when finalized. Open DVD+Rs will make problems (in my case), using IsoBuster is not making sense as it is costly. So I just burn DVD+Rs and as a matter of fact, I will totaly make 10 of them for my tapes as digital archive and also on my discs and cloud as MP4.

Seeing weird QTGMC output in specific areas

I have some old EP tapes that I have been capturing and attempting to preserve. Since a lot of the content is originally interlaced video and commercials QTGMC is the obvious first choice.

Unfortunately I am seeing some weird artifacts with one specific area. In testing I have tried multiple captures using different codecs, bypassing TBC, different vcrs, different capture devices...all with the same result. This one little section on the tape gives QTGMC the fits.

The front of the car should look something like this

QTGMC on its own makes it look like this every other frame, creating some weird flashing errors (trust me it is hard to miss in motion)
Image
[Attachment 55303 - Click to enlarge]


Basic QTGMC:

Quote:
AssumeTFF()
QTGMC(preset="Medium", InputType=0)
Doubling it up like a repair looks a little better:

Quote:
QTGMC(preset="Slower").QTGMC(Preset="Medium", InputType=1)
Don't see the same artifacts with a simple FieldDeinterlace or TDeint but it introduces other less desirable effects:

Quote:
FieldDeinterlace()
or

Quote:
tdeint(mode=1)

Trying this lends to some jerky 60fps. Every other frame feels like a halfstep:

Quote:
FieldDeinterlace()
bob
QTGMC(preset="Medium", InputType=1)
This is the best option so far:

Quote:
tdeint(mode=1)
QTGMC(preset="Medium", InputType=1)
Just curious if anyone has any thoughts on something to try. I feel like I must be missing something with fixing it within QTGMC.

The entire tape isn't like this. I also have about 12 other tapes with almost 70+ hours in between them so hoping to keep it simple as well.

Thanks.

Io Data GV-USB2 V Dub Proc Amp and Histogram

I'm trying to use the histogram in V Dub 1.9.11 during capture with my GV-USB2 but the V Dub "Levels" function is inoperative with the message "No video levels controls are available with this capture driver".

That doesn't appear to be correct because Video>Capture Filter reveals the Proc Amp on a tab. The problem is, I can't use it live, because opening that tab freezes the incoming video signal. Setting the proc amp controls then becomes a bit convoluted because I have to go out of the proc amp screen to view the live video.

Is there a way of getting "live" proc amp controls with the GV-USB2? I'd be happy to use different capture software is that would mean I'd get access to the live Proc amp.

Thanks! Al
