Deinterlacing in Main Concept encoder

This is the first time I have used Vegas fully.Previously VF2 with TMPGenc for making SVCD's.Results were quite good.
The project I started with required conversion of mono audio to "stereo" and with a logo throughout the video,neddless to say it took forever to render.Seven hours for a 10 minute clip.So when I came to rendering it to MPEG2, I reloaded the avi as a new project and rendered it to MPEG2.
I used the defaults for SVCDPAL (defaults for the rendering of the avi as well)and the result was interlaced on any areas of motion or areas of lighter and darker movement.
With TMPG it has deinterlacing filters which give good results, but I cannot find any thing the same with the Main Concept encoder.
I did look for answers elsewhere but did not come up with an exact answer to my problem.Tried the checking of the "strech video to full....",but wasn't quite sure if that was required to be done on both encodings, any how ended up with a 1/3 to 2/3 vertical split result on the TV screen.

I also used default settings to set the Project Properties.Just for the record I decided to go with Vegas and the Main Concept encoder ahead of TMPG as the cost of both here in Australia is close to double that of the States because of the poor value of the Aussie dollar, matter of finance!

Does anyone have any idea as to resolving my problem.Thanks for any help

If you are looking for de-interlace then in File>properties>Video tab you can set field order to none (progressive scan) & click on advanced button to chooes your de-interlace method.

On your MPEG-2 template for Render As , if you click on custom you can again chooes field order or progressive only.

Each event can be de-interlaced by right mouse clicking on the event and selecting the interlace switch.

I haven't explored further if that's available as part of the output,either as a render or a timeline out back to tape, though it should be.

Tried the Intrelace switch on the whole clip and greatly improved the result for the Mpeg render.Will continue and see if the default settings come up ok.Just a note for anyone with vf2.0,there is a defiite problem with the capture program.I tried 3 different captures and only VF capture corrupted frame and dropped them, Vegas capture was fine.

Actually, that's the "reduce interlace flicker" switch, which doesn't deinterlace.

To deinterlace, pick your deinterlace method from project properties, advanced, deinterlace method, and set your project to progressive, or use a progressive render format. All interlaced source footage will be deinterlaced.

However, SVCD at 480x480 shouldn't be deinterlaced since it is an interlaced format. VCD at 352x240 is progressive, so Vegas will deinterlace any interlaced footage automatically when you render to it, you just need to pick the deinterlace method that fits your tastes.

SonicDennis,

Re: deinterlace vs. reduce interlace flicker. I gather that the latter does just what it says? Can you give me an idea where this switch might be useful?

Thanks,

Sure. "Reduce Interlace Flicker" installs a special spacial filter that blends a certain amount between adjacent scanlines, spreading their energy out a little. It's most useful on things that have high spatial frequencies in the vertical direction, such as generated text, line art stills, and some digital photographs. Images shot with a camera are already filtered by the camera, so they don't need this switch.
