I rendered interlaced i50 always to p50 and not to p25, to keep the smoothness of interlaced. For rendering I only use Voukoder for Vegas with AVC/HEVC.

AVC / HEVC for delivery purposes is progressive only. I've never heard of a GPU encoder that delivers interlaced. The smart deinterlace project setting in Vegas is really good.

Thanks, very helpful. I've always preferred the deinterlaced results from jriver media player or even my LG OLED TV's but it seems I have not done it optimally in Vegas. It would ofc be best to produce a progressive video and I will do some tests, hopefully matching the results I get with jriver.

As i remember, last gpu which support interlaced encoding was 1050ti.

Of course, deinterlace using a software player, hardware deinterlacing on your teevee, and encoder deinterlacing of your source are three completely different considerations.

I haven't seen jriver player in over a decade, but it might be interesting to run some tests.

To use Smart Adaptive Deinterlace in Vegas,

• Change your Project to Progressive
• Change the dropdown to Smart Adaptive
• Use a Progressive encoder template, my go-to is Voukoder with a custom zero-latency preset.

Jriver and the JRVR quality setting is really pretty good or should I say the best I can get out of my options. It's also very stable these days as apposed to a few years ago.

Just realized I might also be getting into scaling issues if I want 1080p out of my 576i source, any suggestions how I should set the resample option? Smart, forced or no resample?

That is a separate question, perhaps better suited to its own thread, so that others may benefit from it

;?)

As to your original question, I have some good news:

• I can see why you like the JRiver player deinterlacing, although I can't tell which algorithm it is using.
• To me, Vegas Smart Adaptive Deinterlace looks every bit as good, maybe even a bit sharper.

No Deinterlace

JRiver Player

Vegas Smart

There are very specific instructions for chaining Smart Adaptive Deinterlace and Smart Upscale in Vegas; they work well, so let's tackle that in your new thread.

Indeed, I just did some tests with the right settings rendering 576p I concluded the same thing or that it was as good as jriver on my LG TV. With 1080p motion was not as smooth but I'll do another thread on that as you say.

And to follow up on my original question it turns out I could not get a proper interlaced AVC/MP4 file, if I changed project settings to lower field first, disabled deinterlace method and rendered with magix avc, cpu only set to 25fps, lower field first the result was as your first picture.

When asking followup questions, please be careful to continue to specify what your intentions are -- to play back on your LG television set, or to deliver your video for others to view, by any means.

That is a huge distinction, and the two are as different as night and day.

For instance, when it comes to playback on your LG teevee, its built-in hardware upscaling will always be better than encoding your file with any form of software upscaling and anamorphic correction, which would otherwise be necessary for delivery by any means: streaming, download, or for upscaled playback on any software player. Bet you didn't know that.
