Sony Vegas de-interlacing issue

[Vman94]

Ive been using sony vegas for some time and all of a sudden im experiencing some serious de-interlacing issues and was hoping someone could help. Seems like the properties function blend fields and interpolate fields have not worked, ive tried all 4 field orders as well. Any ideas woould be appreciated i am batch rendering MP4 files and thats when i see the interlaced(pretty bad lines too). Any help would be greatly apprieciated. PS. Also played with field order in the batch rendering setting.

have you checked the source files? mp4s are not normally interlaced. try mediainfo in text mode and post the results.

Err no im actually editing the dvd so im using the VOB files imported to sony vegas, then im batch rendering pieces of the dvd in sony vegas

what kind of dvd? interlaced? telecined ? how do you have vegas set up ?

[Vman94]

looks interlaced to me. Not sure what you mean by set up, mentioned some settings ive been playing with at the top.

[poisondeathray]

do you see combing in the preview window, when it's loaded on the timeline ? (before exporting) , or only after the export ?

what were your export settings? did you select progressive ?

[Vman94]

Its odd on the preview its fine, but when it starts encoding i can see it on the preview window, but i can scroll through it before encoding and i dont see any problems but when it starts encoding it clearly has problems with lines and such on the video.

[poisondeathray]

If you don't setup the export as progressive, it won't deinterlace it

also, what were your project settings ?

you said "all of a sudden", so that implies your process has worked before (I'm assuming on similar sources)

[Vman94]

Well as far as project settings go. ive tried numerous to try and get it working, i used both de-interlace methods, and all three field orders. 8 bit pixel, full res rendering quality best. motion tyle gaussian, any idea what should i have this at?. Yah ive used this before and i never had that rippling effect on the video, and if i did i used one of the de-interlace settings to clean it up and it seemed fine.

Mp4? Is that your export? Mp4 source is rarely interlace.

What is your source DVD, interlace or progressive? Use Mediainfo.

What is your project setting?

[Vman94]

Yes Mp4 is what im encoding my file too.

[Vman94]

MPEG-PS that progressive?

[poisondeathray]

nope, mpeg-ps means mpeg2 program stream

If you copy & paste the text view (view=>text) , it might provide some information (like PAL vs NTSC), but I don' t think mediainfo will be helpful here, it just reads the header information - it doesn't tell you if the content is progressive or interlaced or telecined. For example it might be encoded as interlaced but have progressive content

when you right click the clip in the clip bin and select properties, what is the field order that vegas thinks it is?

if you have upper field first clip, upper field first project settings, then render progressive it will activate the deinterlacer (either blend or interpolate according to what you have set)

Post exactly what you are doing, what kind of clips (are you importing vob's directly ?), your exact project and render settings

What kind of DVD is this from? Retail ? Hollywood? Copy protected ? Did you remove encryption ?

[Vman94]

Yah its a movie B sorta movie really. when i right click properties i get upper field first. and tried progressive none on render and still its all jittery. the clips are VOB and i used DVD decriptor to put in on my hard drive to start.

[poisondeathray]

By "jittery" - if you mean forward, back , forward , back, etc. ... usually indicates reversed field order

Try setting to lower field first, the project settings to lower field first, and render settings to progressive

If it's a recent release, then dvd decryptor might not work (hasn't been updated in a few years against newer copy protections)

If you post a sample clip, we can provide more information on what the movie really is and how to deal with it

Vegas' deinterlacer is crap.
Use Avisynth (best/slowest) or VirtualDub (good/faster) to pre-process before Vegas.

[manono]

If it's a movie it shouldn't need to be deinterlaced at all - maybe IVTC'd, maybe unblended, but not deinterlaced - since movies, by definition, are progressive. As pdr suggested, upload a piece of it, 10 seconds with steady movement. Open a VOB in DGIndex. Use the [ and ] buttons to isolate an appropriate piece, and then File->Save Project and Demux Video. Upload the resulting M2V to MediaFire or Sendspace.

And why is Vegas being used at all for this work? Pieces can be cut and joined using other programs.
