Hello!
Does anyone have an idea how I can remove darker double outlines next to very bright objects in Video8 clips? This image disturbance seems to be caused by very high contrasts and can be found again and again in my video clips.
Attached you will find an uncompressed and a compressed example video file as well as a screenshot of the image error. In this sample video, the image error can be seen several times, each next to the flames.
Thanks in advance!
Ralf

Hallo!
Hat jemand eine Idee , wie ich dunklere Doppelkonturen neben sehr hellen Objekten in Video8 Clips entfernen kann? Diese Bildstörung scheint durch sehr hohe Kontraste ausgelöst zu werden und findet sich immer wieder in meinen Video Clips.
Im Anhang findet Ihr eine unkomprimierte und eine komprimierte Beispiel-Videodatei sowie einen Screenshot des Bildfehlers. Auf diesem Beispielvideo ist der Bildfehler mehrfach, jeweils neben den Flammen zu sehen.
Besten dank schon im voraus!
Ralf

Hello Ralf. When you play these tapes on another device or directly on a TV, do you see these dark lines?

Hello Jim!
Unfortunately, these artifacts are also visible when played back on another recorder. They are therefore also visible on the recordings that have not yet been deinterlaced. With DeHalo you get a little weaker, but the recording is also significantly blurrier.
Greetings
Ralph

Leider sind diese Artefakte auch bei Wiedergabe mit einem anderen Recorder sichtbar. Sie sind daher auch auf den noch nicht deinterlacten Aufnahmen sichtbar. Mit DeHalo werden Sie etwas schwächer, aber die Aufnahme auch deutlich unschärfer.

Google Translate.

How the error was caused can determine how it needs to be addressed.

- Is this "found source"? That means the video is not yours, but just something you downloaded online.
- Or is this your own Video8 tape conversions? If so, what camera, TBC, and capture card was used to do it? What software was used?

Very often, bad capture methods are to blame for bad quality. The original video was not bad. Redoing it is the actual "fix" in those situations.

__________

Wie der Fehler verursacht wurde, kann bestimmen, wie er behoben werden muss.

- Ist das eine "gefundene Quelle"? Das bedeutet, dass das Video nicht Ihnen gehört, sondern nur etwas ist, das Sie online heruntergeladen haben.
- Oder sind das Ihre eigenen Video8-Bandkonvertierungen? Wenn ja, welche Kamera, TBC und Aufnahmekarte wurden dafür verwendet? Welche Software wurde verwendet?

Sehr oft sind schlechte Aufnahmemethoden für die schlechte Qualität verantwortlich. Das Originalvideo war nicht schlecht. In solchen Situationen ist es die eigentliche "Lösung", es zu wiederholen.

By your description I was going to guess that this would be a YC delay/alignment issue, but the actual footage almost looks like it was originally that and then amplified by being a multigeneration tape where it compounded more and more with each transfer. I take it that's not the original recording you have there?

You can try YAHR() filter in avisynth
also:
FastLineDarken(luma_cap=28,thinning=220) ( adjust values according to the source)
another:
DeHalo_alpha(rx=1.6,ry=1.6,brightstr=1.0,highsens= 60)

Last but not least:
FixVhsOversharp(30,14,10) #
