Any way to Force Deinterlacing with VSPx7?

[Troy at TheGTAMblog]

I am using the Trial/Demo of VSPx7 [and loving it so far ], I just have a file at the moment that was created by someone else which has hard-coded interlacing. By that I mean, the file is Progressive, but there are Interlacing artifacts present within it (the combing/mouseteeth/lines).

I realize that VSP will automatically deinterlace a file if it is interlaced and the desired output is Progressive, but this file isn't in an interlaced format and I'm not sure if VSP would detect it through analysis of the artifacts themselves and I don't see a Deinterlace FX/filter (it would be nice to be able to choose what type as well, such as Field Discard, Mean, Blend, etc).

Just wondering if there is a way to force deinterlacing on a clip that is Progressive, with VSPx7

Hi

Can you provide the full properties of the problem video file, right click the clip in the timeline and select properties, what are they?
You could create an image of the window and attach to your post.

You can render the video to use Upper field or Lower field to create an interlaced video, whether that will cure the jagged edges is to be seen, my first thoughts are that it may not help as the jagged edges are embedded within the progressive video.

Anyway the best option is to use Settings Movie Profile Manager to create a new template, using the Add option will create a template using your video files properties, first choose your video format (I assume AVCH264) then browse for your file.
Edit the template changing only the Frame Type from the General tab : choose Upper Field rather than Frame Based

By the way what does it indicate as the frame type before changing anything.
The template will be available from Share – Avch.264 –profile options.

As I say it may not work, maybe the interlacing used earlier is lower field, besides how is Video Studio gonna recognise the interlacing within a progressive file??????

Haha That's what I was saying!

The file itself is progressive, so I don't know whether they were doing some Telecining that didn't take (the clip is 25fps but NTSC not PAL/SECAM) or was doing it on purpose, but there is clearly interlacing/lines showing in a 480p video...

Thanks for the idea of changing the output, I was experimenting a bit with that, re-rendering it in Fields and seeing if any players deinterlaced it 'properly'. I might try re-importing the UFF or BFF re-render back into VSP and see if it detects the interlacing and 'takes it out' along with the actual now-interlaced file...interlacing when it processes it. This feels like dealing with Time Travel - kinda fun

The file itself comes up as Frame Based in VSP. Here is the full Mediainfo metadata:

So, it's not AVC, they used simple MPEG with a PAL frame rate and NTSC frame resolution (which is why I thought maybe they were trying some Telecining and it didn't take).

Thank you for all the workaround ideas. I was looking for an actual Deinterlace FX/filter or something that could be 'forced' to process the video, but I didn't see it. To answer your question, the only video editing application that I know of off the top of my head that can actually 'detect' interlacing in a progressive file is Nero Video (they use motion detection and something else I can't remember, but I assume it would also process things like bare branches on trees in winter as interlacing, but I haven't tested that assumption). I usually used other little Freeware editors to force deinterlacing (like Virtualdub or Avidemux), but was seeing if there was a way to 'do it all' in VSP.

Neat little problem anyway, I'll have fun messing with it for a while

Can you not ask them for the original movie?

Can you not ask them for the original movie?

It was produced by a company and although they are still around I'm not sure they would even have the originals anymore (it's older now), but no harm in trying... Perhaps I'll do that with the portions that show the obvious interlacing

It seems that my question is answered anyway, from input and through my own researching, there seems to be no way to 'force' VSPx7 to de-interlace material (or adjust how it deinterlaces clips manually). Not a big strike against VSP really though, as it still seems to do fine on it's own at detecting interlaced video and adjusting for the region I stated I am in, and it allows interlaced output, if that is something I needed. Thanks anyway for the input, all - a helpful thread, as always here
