Can you clear something up please?.
You've de-interlaced it.
Did it look like interlaced VIDEO to begin with, or had it been broadcast looking like film?
If the latter, then what you've done is fine. BUT, if it looked like a live video broadcast and you've changed that look in the deinterlacing process and it now looks like it was shot on film, then that's a massive "NO NO" to me...

The only other issue is HEVC. Whilst it's a superb codec and allows you to keep interlaced programmes interlaced with no problems (unlike .264), it's not very user-friendly for the masses.

It does look interlaced (horizontal line artifacts and whatnot) and most importantly MediaInfo reports:

Scan type: Interlaced
Scan type, store method: Separated fields
Scan order: Bottom Field First

Which I took into account to process it. It looks nicer now IMO, but there's room for improvement for sure. In any case, feel free to check it yourself and process it as you wish, if you are so inclined. It is apparent that the original file has got a number of tech issues, we should look further into it.

Regarding device support, I am aware that HEVC and FLAC are not the most friendly codecs compared to MPEG2/AC3 (ancient) or x.264/PCM (compatible with most devices today), so once again feel free to process the original file to suit your needs.

I checked it via VLC, VirtualDub and Avisynth. Didn't appear interlaced to me. At least not in a classic sense. It may have some combing artifacts.

Scan type, store method: Separated fields

That's interesting, it says the fields are already separated. So it does appear as progressive to the eye. Need to dig deeper into this.

Edit: Only the scrolling credits at the end appear to be proper interlaced. The main thing is progressive 25 fps. So that's how it is.

awesome! thanks!

Anything Brian & Roger does without Adam Lambert would be a huge improvement in there credibility.
They should be moving on making music with some of the biggest names in the music industry before its too late.
Stop wasting your energy on a yanky twat.

It's so weird to remember Midge Ure from the 80's and then see him in a 2010 video :-) Thanks for this

this has been one of the best things made by Brian and Roger after 1991.

Thank you very much, I was looking forward to a recording like this one.

Thank you very much.

Thank you so much, once again! It is truly fantastic!!!

Just wondering: how do you explain the fixed moiré effect on the Prince's Trust red & white logos, as well as aliasing gone on high contrast straight lines (e.g. guitar strings)? If that wasn't corrected by deinterlacing the video, what fixed it?

I'd swear I saw interlacing artifacts when I played it on VLC in my work computer, but I don't see them at home. I wonder if there's something particularly different in terms of video drivers, playback configuration and whatnot.

Also, I tried a higher bitrate encode with the same parameters at 4096 kbits, but the logos flicker and the straight lines shimmer like in the original. Perhaps it's closer to what it should be, but I wonder exactly what's going on.

Deinterlacing usually doesn't fix those types of artifacts. I haven't particularly researched about moire but aliasing can easily be fixed via Avisynth.
What exactly caused it, I'm not sure. Probably something in between the generations the video went through from the camera to this file. It's rare that I deal with these kind of digital HD broadcast videos. As you may guess, most of my sources are DVD rips :) And sometimes ProRes film scans.

By the way, I noticed that the video sometimes briefly glitches out some interlace artifacts during the main feature too (not sure if it does in your encode, I didn't have time to examine it). It's a bit of a mess, this source.

Thanks!

Big Thanks!

Thank you very much.

Thanks a lot! :)
