DVD-R backup worse than 1CD-DivX?!

[Sergei.Gradski]

Hi...

I've finally finished making a backup of Herbert Grönemeyers Mensch live, but the quality is not exactly what I'd have expected.

The source had been interlaced, I deinterlaced it with the AviSynth-Script according to Doom9's Scenarist NT & the big 3 guide. Generally, I followed this guide step by step.

Still, I could have got better results with a 2CD DivX-Rip... Have a look at this (two clapping hands):

Additionally, despite following the guide there's no menu on the new DVD... And I absolutely don't know why. I still have all the project files, please let me know what information, which logs are needed for helping me...


:confused: :confused: :confused: Thanks in advance...

I thing your AviSynth script was (almost) looking like this:
Import(“X:\xx\DoItFast4U\new.avs\addaudio.avs”)
LoadPlugin(“X:\xx\DoItFast4U\new.avs\decomb.dll”)
LoadPlugin(“X:\xx\DoItFast4U\new.avs\mpeg2dec3.dll”)
Mpeg2Source(“x.d2v”)
FieldDeinterlace(blend=false)
AddAudio()
ConvertToYUY2(interlace=true)
Do you see the ConvertToYUY2(interlace=true) command? It says you video is interlaced, but you deinterlaced it before (FieldDienterlace(…)), so it isn't interlaced anymore at that point.
To solve this, you should switch the order of those commands.

I think you should use KernelDeinterlace instead of FieldDeinterlace. It gave me a better result (Whit these settings: kerneldeint(order=1,twoway=true,threshold=5))

[Sergei.Gradski]

I definitely set it to interlaced=false. I asked about this before encoding (actually while encoding, but I did another run because I screwed the first one), and then I set it to false. By the way, it looked the same with "true". I'll have to go home today which means a trip of 400km, but when I'm there and when I have rebuilt my computer again, I'll try that. So long...

Just don't deinterlace and you'll be fine.

I heard (and experienced a few times) the deinterlacing result is better if the source is YUY2 than if the source is YV12. So, I suggest you switch the two commands in the script, and give it another try. In that way, I never got shitty videos anymore...

Although I don’t think deinterlacing is the best, cause the original is still looking much better.

My take is...just DON'T deinterlace, period. No matter how good the filter is is gonna have problem at some point somewhere, and after all DVD MPEG2 supports interlaced video (unlike the old MPEG4 Divx for example).

How do you get hq video's without deïnterlacing?

[HyperYagami]

It's a matter of taste. To me seeing those artifacts is worse than seeing blocks. For example, whenever I get a scene with fine lines in it those deinterlace filters destroy it immediately. To me, doing interlaced CCE is enough, and in a sense preversing the original as much as possible (where when you deinterlace you're not). But as I said that's just me, different people have different opinion about it.

[DeeD2k2]

I can't say you aren't right and I wouldnt even try to! I think my eyes are more trained at blocks then lines, cause I rather watch al VHS tape than a bloky DVD... As you said, everybody has his own definition od visual quality.
Thank you for your resonse and makning clear hq video's can be blocky for some people. After this discusion I won't bother anyone again with discusions about quality.

Cheers
