View Full Version : De-Interlacer, Sharpener & Transition Question

Hi there. I'm getting back into my video editing hobby and have two questions.

I'm working with DV Type 2 AVI (720x480). I am using VirtualDub 1.8.5 and the Deinterlace filter on the Blend setting.

This is a before-and-after comparison.

Before (ftp://avisynth:forum@71.7.230.186/Interlaced.jpg)

After (ftp://avisynth:forum@71.7.230.186/DeInterlaced.jpg)

I realize that deinterlacing (or blending) leaves a blurred effect and thus a slight loss of detail.

Question #1: Should I be using a different deinterlacer and/or a sharpener to "restore" some of the detail?

Question #2: Normally I would be importing the video into Adobe Premiere Pro CS4 and adding in a few basic transitions (title, fast-forward).
My question is, is there a plugin for AviSynth that will "blend" or "merge" two sections of video together? What I mean is, in some videos someone is talking and there is a smooth transition that "jumps" or "skips" to another segment of the video. This is much more desirable than to do a normal cut of frames in VirtualDub. Am I being clear?
If there isn't something like that for AviSynth than I can use APPCS4.


Thanks,
Jeremy

simply don't use the 'blend' setting!

very high quality deinterlacers for avisynth are for example:

1) yadifmod with nnedi
2) tempgaussmc

I've played with some plugins for deinterlacers and so far I like TDeint the most with the following code:

TDeint(mode=2, order=0, field=-1, type=3)

This is my original Interlaced frame (ftp://avisynth:forum@71.7.230.186/Interlaced.jpg).
This is the deinterlaced frame done in VirtualDub (ftp://avisynth:forum@71.7.230.186/DeInterlaced.jpg).
This is after using TDeint. (ftp://avisynth:forum@71.7.230.186/04. TDeint.jpg)
The main difference is that in VDub I use the Blend option and in TDeint I use the BFF option.

I'll give Yadif a try still.

There's a yadif for VirtualDub that works quite well.

Yeah, just tried it but I like TDeint better. Cheers.
