HELP!! BFF or TFF WHEN RIPPING DVD

[Sharc]

someone asked about my screen settings,.....

I have been asking for the monitor's refresh rate which is 60Hz in your case. As 60Hz is not an integer multiple of 25fps you would always get a little judder on PC (if this judder is what you are wondering about when others say your files play smooth).

[Sharc]

How would I see that the video is encoded with field structure? From the header? MediaInfo reports "fields", but ffprobe reports 'interlaced_frame=true'.

gspot and dgindex can also report frame structure

The value is reported under the picture_coding_extension , picture_structure will report "3" for frame picture, such as in Skiller's re-encode . Those 2 samples report "2" which is bottom field

Table 6-14 in the ITU Rec. h.262 document lists the values

Thank you. So I can't detect it with 'ffprobe -show_frames', it seems.

yes could be my premium Zidoo UHD3000 £1000 media player, but don't think so.....

There obviously is a problem with your player. All the m2v files you've uploaded are DVD compliant and should play properly in any player, especially a premium player. Complain to Zidoo. Send them a sample.

Kodi on my Google TV plays them properly. The Google TV version of VLC does not -- probably the same jerkiness you're seeing. The Google TV version of VLC is very crippled compared to the Window version.

Kodi on my US$20 Android TV plays the videos properly. VLC plays them with a black screen.

@Johnnysh: Did you ever try skiller's variant of post#18 and report back? That would clarify a lot regarding your playback sceanrios and the Zidoo.

Hi All

Well just set VLC player to "on" (not automatic) and "Yadif (2x)".

and these files do not play silky smooth!! the play same as before blury non fluid ??


This interlacing of TV show is a real pain in the .....

Guess i will strip chapter and get rid of the interlacing once and for all with QTGMC

Hello Guys

well time to QTGMC


could someone please advice the best LOSSESS QTGMC settings to convert MAKEMKV chapter rip to mov / mkv etc

SetFilterMTMode("QTGMC",2)
FFMPEGSource2("LB1_t00.mkv",atrack=1)       # make -1 if no audio ???
ConvertToYV12(interlaced=true)
                                                                    #ConvertToYUV422(interlaced=true)
AssumeTFF()                                                 # Assume Top Fild First
#crop(5, 2, -5, -2)
                                                                       #Crop(0,0,704,576)
QTGMC(preset="Slower", EdiThreads=6, Sharpness=0.5)
                                                                       #QTGMC(Preset="slow", EdiThreads=3, SourceMatch=3, Sharpness=0.5, TR2=2, Lossless=2)
#BilinearResize(720,576)
                                                                       #''BilinearResize(640,480)
                                                                       #LanczosResize(720,540)
                                                                       #Spline64Resize(720,540)

im guessing DVD is 4:2:0 8bit ??? so is this part right

ConvertToYV12(interlaced=true) ?



then in virtual dub 2 what do I output to for 100% lossless QTGMC from the original MKV file

the quality is so bad any way from the original DVD rip after the de interlacing I don't want to lose any further quality

any advice much appreciated

[Sharc]

the quality is so bad any way from the original DVD rip after the de interlacing

The quality is probably bad before deinterlacing and has little to to with QTGMC(), but anyway:

QTGMC(Preset="Fast",lossless=1)

It keeps the field untouched which is however not the "best" for the deinterlaced quality.

If you want to re-interlace for your player:

QTGMC("Preset="Fast",lossless=1)
separatefields().selectevery(4,0,3).weave()

[Johnnysh]

thank you for your reply


so I now notice on the top line a flicker ?? its almost as though i need to crop the 1st line to get rid of the flicker, but the crop command gives an error

and yes your right the quality is low grade BBC TV DVDs made by EUREKA, that company is a Total Disgrace converting quality TV series to ultra low grade DVD

SHAME ON EUREKA, what a tin pot outfit, shame a professional company never was involved


so is below the very best quality for de interlacing hours of DVDs

I have played around with so many setting tonight, Im totally lost now

I have even converted to 422 but can't see the point as its low grade dvd

what compression settings should I choose







SetFilterMTMode("QTGMC",2)
FFMPEGSource2("LB1_t00.mkv",atrack=1) # make -1 if no audio ???
ConvertToYV12(interlaced=true)
#ConvertToYUV422(interlaced=true)
AssumeTFF() # Assume Top Fild First
#crop(5, 2, 5, 2)
# Crop(0,0,704,576)
#QTGMC(preset="Slower", EdiThreads=6, Sharpness=0.5)
QTGMC(Preset="Fast",lossless=1)

#QTGMC(Preset="slow", EdiThreads=3, SourceMatch=3, Sharpness=0.5, TR2=2, Lossless=2)
#BilinearResize(720,576)
#''BilinearResize(640,480)
#LanczosResize(720,540)
#Spline64Resize(720,540)
#LanczosResize(696,520)

thanks in advance

when I add this

separatefields().selectevery(4,0,3).weave()


I get an error ??


not sure why but it does not like this command

[jagabo]

Note that the lossless modes of QTGMC keep the original scanlines of a field and fill in only the in-between lines (the other field). That leaves the original lines intact but limits the ability of QTGMC to remove aliasing/buzzing artifacts. So the visual quality is generally lower with the lossless modes.

The output of ffmpegsource2 is probably already interlaced YV12 (you can use Info() to find out for sure) so you don't need to ConvertToYV12(interlaced=true).

YV12 video cannot be cropped by odd values. All values must be mod 2 or more. I recommend you keep to a final mod 4 frame size. If you plan on re-interlacing YV12 video you must keep a mod 4 frame height. Keeping small black borders is no big deal. Since your DVDs are obviously ITU caps I recommend cropping a total of 16 columns off the left/right edges, leaving a 704 pixel wide frame. Then encode with a sampling aspect ratio (SAR) of 12:11 for 4:3 material, 16:11 for 16:9 material.

The faster presets in QTGMC deliver worse quality than the slower ones. If speed isn't an issue consider using slower presets.

separatefields().selectevery(4,0,3).weave()

What error? When you seek at random along the timeline using the slider in VirtualDub2?
Maybe remove from your script:
SetFilterMTMode("QTGMC",2)
Prefetch(10)

But anyway, you would need the separatefields().selectevery(4,0,3).weave() only for re-interlacing when your player requires interlaced video.
