SD 50i to HD 50p upconversion and deinterlacing
Hi all
I have some old SD footage (PAL 50i) which I digitalized from tapes. I realized that I can improve the quality a lot by up-converting to HD and apply some filters then (i.e. unsharp mask). But I’m not sure how to do this correctly in Vegas.
I would like to convert the SD 50i to HD 50p also using a de-interlacing filter (I liked the results of BCC de-interlace). How should I configure Vegas, apply the de-interlacing filter and do the up-converting?
– I found a tutorial that suggests setting the Vegas project settings to double PAL progressive and then apply YADIF as a media effect. Can I do the same with BCC de-interlace to achieve best 50i to 50p conversion?
– Should I set the Vegas project settings to PAL SD or to HD and then import my SD footage?
– Should I up-convert using BCC uprez or similar or should I just render to HD?
– Should I apply filters like unsharp mask in the same project or render first to HD and then apply my filters in a second project?Sorry for the many questions. But I think for de-interlacing to work properly I should use an SD project and for sharpening and up-converting I should use an HD project. Therefore I’m a little confused.
Thanks a lot for any help!

For upscaling and deinterlacing my old SD videos I use SimpleSlugUpscale (google for it). In addition, I stabilize videos using deshaker plugin for VDub (imho it works better that Vegas stabilizer). The resulting videos (encoded by loseless coded) I use in Vegas.
A little example:
Source (MPEG2, PAL, 50i)
Deinterlaced + Upscaled (MP4, 1024*768, 50p)
Deinterlaced + Upscaled + Deshaked (MP4, 1024*768, 50p)Some details were lost by transcoding from loseless AVI to MP4.
P.S. I wrote bat-file that help me to do that. I simply select files in Total Commander, press custom button on toolbar and voila (after a few hours 🙂 ).

I think I found the solution for this problem in Sony Vegas:
1. Open a Vegas project with HD settings
2. Import the SD footage
3. Apply the de-interlacing filter not as a track or event effect, but as a media effect. That way apparently it will work with the source media resolution and successfully de-interlace my media.
4. Apply all the other effects as usual as track or event effects and profit from HD resolution.
5. Render to HDSome important points in my case:
– I applied BCC deinterlace in Boris RED as a media effect. But Boris RED recognized my HD project settings and used those. I had to manually change the Boris RED project settings to SD for the de-interlacer to work!
– My SD footage is quite blurry. Boris uprez didn’t make a big difference compared to just importing the SD footage to Vegas. But applying BCC unsharpmask in an HD project instead of an SD project made a huge difference!Best,
Stefan
