Using S-video and OBS right now. Just received the capture card in the mail. The driver was easy to install with the included driver CD and the Google Translate app on my phone. You just point your phone at your computer screen and it translates the Japanese to English. Haven't received my DVD recorder for a TBC yet.
update: added amarectv capture
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

I'll leave the main analysis to those who know better than me but.....
Whether this is an issue with the codec, OBS or the card but chromo sub-sampling for NTSC should be 4:1:1. and not 4:2:0 which is PAL
Also the DAR appears to be 16:9 and VHS does not support that without letter-boxing.
Personally I would do another sample with AmarecTv or Vdub just to compare the output. -

The architecture of the fields is weird in both captures.
Run a simple separateFields() and check by yourself
Proportions also looks weird
edit: 4:2:0 colorspace in obs capture is not appropriate, should be 4:2:2
edit 2 removed comment on field architecture, is classic 3:2 pulled-down, sorry for my mistakeLast edited by lollo; 22nd Jun 2022 at 16:45.

Ok I will switch to UT video and try that. Does it matter that the io data driver window says NTSC-M and not NTSC?
-
When you step through the frames you see the 3-2 telecine pattern: 3 clean - 2 combed - 3clean - 2combed ......
The files should be IVTCed (InVerse TeleCined) to restore progressive 23.976fps
Code:assumeTFF() TFM().Tdecimate()

Ok. I was fooled by the original cap. Both OBS and Amarec are displaying 3:2
But now Amarec shows 4:2:2 for sub-sampling which is a vast improvemnt on 4:2:0 -
Ok I just installed Avisynth I've never used it. Made an AVS file and when I open it in Virtualdub, it shows this error "AVI Import Filter error: (Unknown) (80040154)"
Anyone know how to fix that error -
You have to add the source filter
Code:AviSource("Path to your source file.avi") #for reading the source file assumeTFF() TFM().Tdecimate()
-
-
if not placed in the appropriate AviSynth folder, load also the necessary DLLs
# plugins directory
plugins_dir="<your DLL directory>"
# TIVTC
loadPlugin(plugins_dir + "TIVTCv105\TIVTC\TIVTC.dll") -
Yeah I did that
-
L-Smash-Works can open Lagarith and UT codec, download and put the LSMASHSource.dll in the plugins directory, 32 & 64 bits as appropriate
https://github.com/HolyWu/L-SMASH-Works/releases/
Code:LWLIBAVVideosource("amarec(20220622-1556).avi")
-
I've tried a few things none of them worked
Code:# plugins directory plugins_dir="C:\Program Files (x86)\AviSynth\plugins\" # TIVTC loadPlugin(plugins_dir + "TIVTC-v1.0.26\x64\TIVTC.dll") #loadPlugin(plugins_dir + "LSMASHSource.dll") # file name file_name="C:\Users\u\Downloads\amarec(20220622-1632).avi" #AviSource(file_name) FFmpegSource2(file_name) #LWLIBAVVideosource(file_name) assumeTFF() TFM().Tdecimate()
-
Comment out the loadplugin line, proably a syntax error there somewhere.
It's not required when the dll is in the plugin folder, they're found automatically -

What, specifically, is your error ?
Try installing the latest Avisynth Plus version, which works fine in Windows 7 - 11

Sure. In vdub, unless you set video/compression, it defaults to uncompressed, which is massive as you saw.
If you use vdub2, it has x264, x265 and the excellent lossless FFV1 built in.
If you plan on making a DVD you can open the script directly in HCenc (or AVStoDVD), no need for an intermediate file.
Don't forget the file should play back as 4:3 aspect ratio, so you have to incororate it somewhere -
You may have a 32 bit vs. 64 bit issue. If you use a 32 bit editor you need 32 bit AviSynth Plus and 32 bit AviSynth filters. If you use a 64 bit editor you need 64 bit AviSynth Plus and 64 bit AviSynth filters. For filters to autoload you need to put them in the appropriate plugins folder. plugins+ for 32 bit, plugins64+ for 64 bit.
Note that 32 bit filters often come in a folder called x86, 64 bit filters in a folder called x64. The x86 name comes from the part numbers of the early Intel family processors: 8086, 80186, 80286, 80386, etc. -
Am a newbie and this thread is full of useful info for me. I haven't used Avisynth yet, am I correct assuming it is a tool for post capture editing/processing? So far I have just played with virtualdub's basic deinterlacing/filters in post on some test captures, but I'd like to experiment with something more robust. Sounds like this is the next thing to start getting acquainted with.

If you want an example to setup a basic deinterlacing/denoise/sharpening script in AviSynth look here; it's only a starting point, but I hope it helps: http://www.digitalfaq.com/forum/video-capture/12805-first-video-capture.html#post85085
edit: but first of all you have to understand the nature of your video, to decide if you have to deinterlace, inverse telecine or whatever else. Have a look here: https://forum.videohelp.com/threads/406066-What-is-best-capture-device/page4#post2660663Last edited by lollo; 23rd Jun 2022 at 01:45.

You can also use AvsInfoTool to check your AviSynth installation. It shows whether filters loaded successfully or not and possible filter conflicts and duplicates.
