Compatibility issue with YUV12

[Altruo]

HI

I am having a problem that I did not have previously. I have done many encoding for a cartoon serie using the same script. All the episodes of that serie have the same caracteristics. Laking of time I have stop to encode that serie for couple months. Now getting back to it, my script doesn't work anymore I get : hqdn3d:requires YV12 source (temporaldegrain.avsi, line 82).


Here my script that I use with megui :

DSS2("C:\Users\blabla\Episode 13.1080p.mkv")
TemporalDegrain(degrain=3, ov=4, blksize=16)
Hysteria()

During the last months, I have been playing with my codecs (ffdshow, LAV) for some capturing purpuse, so I obviously touched something that created that problem. The thing is that I just dont know where.

I have tried to add ConvertToYV12() at the end of the script but I get the same message...

I would be grateful if someone could guide me to fix the problem. (Like I said the script used to work and now doesn't work, even on videos that I have encoded in the past)

P.S : Does someone know a better alternative than DSS2 for sources like 1080p.mkv (no audio conversion needed)

Thank you in advance

Add ConvertToYV12() between DSS2 and TemporalDegrain. AviSynth's filters run in a pipeline from top to bottom.

But DirectShow should be your last choice of sources as it's not always frame accurate. Try using LSmashVideoSource or ffVideoSource instead. You'll need to download and add those to AviSynth.

Thanks Jagabo your very helpful

The ConvertToYV12() between DSS2 and TemporalDegrain works. I'll give a try to ffVideoSource and LSmashVideoSource. I still would like to know with what I mess with to get that problem but at least now I can encode

Thank you again

DSS2 uses Windows' DirectShow to open and decompress the video. It's behavior will vary depending on the DirectShow components that are installed. DSS2 isn't returning YV12 video now. You might be able to force it to return YV12 by adding the argument pixel_type="YV12" Or maybe it's format="YV12". I don't remember.
