Questions about Handbrake DVD rip -> QTGMC 59.94 progressive

[_Al_]

ok , no "scan order" or "Scan type" in mediainfo, so that information could not be read, usually it looks like this in mediainfo file:
Scan type : Interlaced
Scan order : Top Field First

if you know it is interlaced, just get that batch script, particular BAT file you use, right click it and choose EDIT, then find this line (line 475):

echo Assume%field_order%()                                                >> "%temp_adr%.avs"

and change it to :

echo AssumeTFF()         >> "%temp_adr%.avs"

or

echo AssumeBFF()         >> "%temp_adr%.avs"

TFF if your VOB is top field first or BFF if bottom field first
if VOB is true progressive, delete these both lines:

echo Assume%field_order%()                                                >> "%temp_adr%.avs"
echo QTGMC(Preset="%QTGMC%")                                              >> "%temp_adr%.avs"

so avisynth would not deinterlace, or just add there character for info to disable those lines in Avisynth:

echo #Assume%field_order%()                                                >> "%temp_adr%.avs"
echo #QTGMC(Preset="%QTGMC%")                                              >> "%temp_adr%.avs"

I just want to make sure, this tool is not for commercial DVD's, just interlaced DVD's 4:3 or 16:9, home made DVD's or even bought DVD's but only if this is true , to apply QTGMC. Your looks like it is 4:3 or 16:9 but might not be interlaced.

Handbrake would not deinterlace using QTGMC or other tools with GUI. Home made videos are like that. Sources for home videos were interlaced. And interlaced video is 4:3 or 16:9 only. So that is why while back I did this script to not doing it tediously manually all the time using DGindex, audio converter and constructing Avisynth because of QTGMC then muxing it into MP4.

If aspect ratio is not one of those 4:3 or 16:9 (perhaps not your case) or video is telecined 23.976 to 29.97 this tool is not a right choice, it would not work, no point to use it, there is tools like Handbrake or other tools that do a job perfectly.

Thanks.

I think I got the info you wanted me to give:

Frame Size: 720x480
Display Size: [not specified]
Aspect Ratio: 4:3 [2]
Frame Rate: 29.970030 fps
Video Type: NTSC
Frame Type: Interlaced
Coding Type: B
Colorimetry: BT.470-2 B,G*
Frame Structure: Frame
Field Order: 
Coded Number: 276958
Playback Number: 2
Frame Repeats: 0
Field Repeats: 0
VOB ID: 3
Cell ID: 26
Bitrate: 
Bitrate (Avg): 
Bitrate (Max): 
Audio Stream: 80: AC3 3/2 448
Audio Stream: 81: AC3 2/0 192
Elapsed: 0:00:56
Remain: FINISH 

It is a commercial DVD with 5 VOB files.

Without QTGMC() [ver. 3.3], and Restore() the video will look trash as the badly mastered commercial DVD I have.

There is all kinds of DVD's out there, that need special approach after providing a sample, guys here know what they are doing and can recommend special sequence of filters in Avisynth to fix DVD if it is possible. If it was done by NLE or in some authoring as interlaced DVD, mediainfo would be more specific about scan order or fields.

You can use that BATCH script, BAT files to just construct avisynth script automatically and stop the script. Script could be stopped with pause line added in batch script also, right after batch script creates Avisynth script. Then you go to TEMP folder adding filters in Avisynth script, fixing it, restoring it copy and pasting recommended filters and dropping it in VirtualDub or MPC-HC using step feature what you got, getting visual feedback what filter did what (good or bad). After Avisynth script is fixed you just let the script continue. Never tested it that way if ffmpeg handles DTS audio as well, maybe yes, basically it is marked as AC3 anyway. You can delete all parts in the script that encode audio (deleting lines that starts with :encode line and about 10 lines or so), just leaving audio listing at the beginning as sort of visual what that DVD got, what audio tracks and listen to them. Whatever objective there is.

If using anamorphic MPEG to anamorphic MP4.BAT and commercial DVD:
You'd need to also check x264 command line to manually write correct SAR because script would not come up with any SAR, it would fail there, if encoding anamorphic video BAT, but that one folks do not encode anamorphic videos, if at all. Anamorphic encoding is good for back up , archived video with a goal for later editing, so interlacing is removed and not actually resizing anything yet. Just including SAR info in command line. even if that is excluded no big deal, it can be interpreted as NTSC or PAL in video editor later.

Thanks for suggestions.

Made changes to BAT file and AVS file.

The results are satisfactory. There is an audio sync issue which I dealt separately. The job could be easier and faster if I knew how to split H264 file.
