lines on picture after edit

[efiste2]

After editing an action clip from a dvd, the edited file has lines across the moving parts of the video, still or slow moving objects are ok, but the faster moving objects such as fast cars etc seem to have lines across them......Im afraid im a bit of a noob, but I have heard someone call it interlacing is this correct or am i way off the mark ?

It sounds like you're having problems with interlaced video.

What is your source (container, codecs)? What are you making (container, codecs)? What software are you using?

[efiste2]

I have selected De-interlace in my conversion program (Handbrake) and it seems to have cured the problem somewhat. Thanks for the advice, Im afraid I just drop the video file (vob) into handbrake and select IPAD, and i just let the program do it.....but the codec (handbrake tells me) is H264.....It seems only when I edit the original VOB file from the DVD using VideoREDO, that I get this effect, but as I say selecting Deinterlace in Handbrake seems to help solve the issue....as a side note some of the files are NTSC region1.....if that makes a difference .Thanks again

If these are movies deinterlacing is the wrong thing to do. Maybe make available a short 10 second sample, one with steady movement.

as a side note some of the files are NTSC region1.....if that makes a difference .Thanks again

It does.

Its really hard to make out via YouTube, but very very apparent on my PC, this clip was ripped from a DVD R0, using DVD Fab5 then AViDEMUX to catch a 5 sec clip....The lines appear on the rotors of the Helicopter....but as I say its hard to spot on the youtube version.....Is this of any use to you guys, in helping me to aleviate the problem..if not how do I upload a clip that the problem can be seen on....

[jagabo]

You should demux a short segment and upload it here. Youtube reencodes everything so there's no way of telling what the source really is.

[manono]

Is this of any use to you guys, in helping me to aleviate the problem?

No

...how do I upload a clip that the problem can be seen on?

Open a VOB in DGindex. Find a suitable spot with steady movement. Use the [ and ] buttons to isolate a short 10 second section. Go File->Save Project and Demux Video. Upload the resulting M2v here.

[efiste2]

Thanks for sticking with me on this one.......ill get on the case.

[efiste2]

Apologies for another noob question but do I upload the file using the My Files method within this fourm...?

Heres a screen cap I got while using the DGindex tool this shows the effct I am getting...

Hoing this works...

[jagabo]

Yes that file is fine. Your video is interlaced, bottom field first. Each frame has two half-pictures, intended to be viewed separately, for 1/50 second each. What exactly do you want to do with it? Here's a 50 fps MKV file made with AviSynth, QTGMC(), and x264. Handbrake can't do this double frame rate conversion.

[efiste2]

THANK SO MUCH Thats is brilliant, your knowledge amazes me.....:-0

as for using AVISYNTH, is this all I need, as in to extraxct a clip from the Vob file, is QTGMC and X264 a setting within Avisynth , agaon apologies for being thick

[efiste2]

Just downloaded AViSynth and it just installs a folder onto my PC, im assuming it needs a GUI or something.....Is the process you used a difficult one , or would it be possible for you to give me a quick HOW TO.......

[jagabo]

AviSynth works in the background via text scripts.

http://avisynth.org/mediawiki/Getting_started

Getting QTGMC() working is a pain because you'll need to download and install several third party filters.

To open VOB, MPG, or M2V files you'll want to use DgIndex to build an index file. You've already got the DgMpgDec package, you'll just have to put the DgDecode.dll file in AviSynth's plugins folder. Then use a script like:

Mpeg2Source("Chinook.demuxed.d2v") 
QTGMC()

Finally, you open that script with a program that supports AviSynth scripts. Like VirtualDub, the command line x264 encoder, or Xmedia Recode.

[efiste2]

thats pretty complicated for a lamen like me, I dont suppose there is a program that can do the process in one is there ? ...........

[jagabo]

There are lots of free conversion tools that will get you single frame rate deinterlacing. None is as good as QTGMC(). Try tools like Xmedia Recode, Handbrake, Xvid4PSP, MeGUI, etc.

Im trying to get a grip on this, and thanks AGAIN for sticking with me, i have opened DGindex and it allows me to get the part of the video I want.....Is this file the INDEX file ? its been saved as an m2v file.....Is this correct ? the next step is to get the DgDecode.dll file where do i get that from, or do I already have it ?

[manono]

i have opened DGindex and it allows me to get the part of the video I want.....Is this file the INDEX file ? its been saved as an m2v file.

That was for getting the sample M2V for upload. Just use 'File->Save Project' in the future. Although, along with the M2V you also got a D2V and an audio file. Right? It's the D2V you need for the AviSynth script.

the next step is to get the DgDecode.dll file where do i get that from, or do I already have it ?

You should have gotten it already when you got DGIndex. They're both part of the DGMPGDec package.

While you're there, in that same DGMPGDec package are three very good docs explaining very well how to get started with AviSynth. Read them all half a dozen times.

Before I get totally lost, I have found VIDEO ENHANCER that is recommended for de-interlacing, And I have had a mess around with it and it has lots of options/filters and codecs but it doesnt have the X264 codec option which it recomends.....I have dwnloaded the X264 codec, installed it, but it is still not an option within the VIDEO ENHANCER program, sorry to side track the main issue, but If I can get this program to work it looks as though it will do for what I want .....

[jagabo]

I believe Video Enhancer uses VFW codecs. You will need x264vfw.

[efiste2]

Video Enhancer combined with the codec you guys told me to use is good enough for me and my Ipad videos, so thats great.....THANKS SO MUCH to you guys that stuck with a lamen and sorted it for me......Once again THANKS!!!!!!
