Interlace problems

[Gionna]

Hello,

I'm a student and for my project I have to work with data that come from video tracking. I'm using a software (Tracker) to do this but I have a big problem with the frame rate and the spatial resolution.

My video is 1920i/60 and when I open it with Tracker, it uses the Xuggle engine to read the video with bad results. So I need to deinterlace the video before open it with Tracker.

So my problem is:

is possible to deinterlace my video keeping that frame rate (60) and also the resolution?

Thank you for your help

There is no such thing as a perfect deinterlacer and there never will be. It's impossible to perfectly recreate the original two full pictures from two half pictures. But AviSynth's QTGMC() is currently the best (and very good). Second best is probably Yadif(mode=1), also AviSynth. Yadif is also available in VirtualDub. All of those will give you 60p.

A sample of your video would be helpful. The best deinterlacing algorithm sometimes varies depending on the nature of the source.

Thanks for your answer,
I'm not an expert in programming so I'll try to see how AviSynth works. Cause VirtualDub doesn't read the MOV file, can I use Avisynth to open the file in VirtualDub? and then deinterlace it? or something like that!?

The thing that I don't understand is: what are the steps that I have to do to get the point?

thank you again!!

VirtualDub doesn't read the MOV file

VirtualDub can read MOV files with the MP4 or DirectShow source plugins.

can I use Avisynth to open the file in VirtualDub?

Yes (see below).

and then deinterlace it?

Yes. Though if you're going to open the file in AviSynth you might as well deinterlace it there.

From scratch you have a long way to go....

Install AviSynth. Download QTMGC.AVSI and put it in AviSynth's plugins folder.

http://avisynth.org/mediawiki/QTGMC

Download all the other plugins required by QTGMC and put them in AviSynth's plugins folder. Create an AviSynth script (a plaint text file with .AVS as the extension) that reads something like:

DirectShowSource("filename.mov")
AssumeTFF() # or Assume BFF(), whichever is appropriate for your source
QTGMC()

Or:

ffVideoSource("filename.mov")
AssumeTFF() # or Assume BFF(), whichever is appropriate for your source
QTGMC()

The latter will required you download and install the ffmpeg source plugin for AviSynth.

Finally, you open the AVS file with VirtualDub as if it was a video file: File -> Open Video File.
