Generally the problem I see with mp4 is that people encode the files way too
small. Used to get some decent quality content off www.archive.org
<http://www.archive.org/> when people did MPEG-2, but as they started using mp4
the files were just way too compressed.

I didn't see any errors and watched it again specifically looking for them.
The next step would be converting it to 14x9 like MeTV, almost wide screen,
but barely noticeable that it isn't full screen.

This is a large mp4 encode rate of 2.2 MBits. Examples of MP4 encoding
errors.
00:06 Car hood.
00:16 Collar
00:38 Her Face.
Etc.
I am not saying it is not tolerable watching the video. But when you put
it into a server, the server decodes it back to uncompressed video to send it
out the video port. Then the on-air encoder recompresses it and is going to
see those “flutters” as details, and use up more bandwidth trying to
reproduce it.
This is a big problem with black and white. Color video does not have near
the problems black and white because it is reproducing less color
information. With black and white, it is trying to produce all of the colors
to make perfect black and white. The Mpeg2 and Mpeg4 codec folks should have
thought of black and white as a “4th” color. Would have taken up much less
information. But they were probably thinking HD Football games, not old
movies.

I'm not so sure about that. If the source video is encoded at a high bit rate
in MP4, the results are beautiful.
Like this. Absolutely beautiful video in MP4 because it was properly restored
and encoded to MP4 correctly, not cheaply:

And this is TRUE 1080p, not interlaced like you mentioned.

The problem with the stuff off the internet is it is compressed so much to
use up less space sending it. It looks awful. So if may show it being 1920 x
1080 HD, but the actual detail within a mp4 video is terrible. It looks like
4-8 bit processing. So if you have a black and white picture with a light in
the background going from white to black, the analog video may have 512
different shades of gray. MP4 is going to cut the back to maybe 4-8 shades of
gray. That’s why when you look at mp4 black and white, the background seems
to flutter even though the original had no flutter. Mp4 is great for the
final leg compression, but it is awful as an interim compression format
because it is taking so much detail out to make the files smaller, it causes
numerous artifacts. You feed that into an Mpeg2 encoder which sees those
artifacts and thinks it is detail and makes them even more pronounced. So
idea would be uncompressed video from the original source to air. But that
would take a lot of hard drive space. So the 2nd best is Mpeg 2 video on the
server to feed you encoder.
And as an added FYI, resolution is based on a black and white line so it
takes 2 pixels for one line of resolution. So 720 x 480 is really 360 x 240
lines of resolution. 240 lines is VHS quality, 260 was ¾” umatic and 1” was
480 lines resolution.

Norm: When I had my LDTV station we ran the Classic TV shows and, yes, I
think the ratings were good. By that I mean many viewers were calling or
sending emails telling me how much they enjoyed the programming. Obviously,
they were older viewers since many had seen these shows when they were 1st
run. The problem is that after you repeat this programming a few of times,
you have to think about acquiring new classic shows and films or changing
formats.
At the time, I was planning on switching my main channel to BizTV and running
classic shows and films on a second channel with a 50’s-60’s rock n’ roll
radio channel as a third sub-channel. A guy who was planning to start a
religious lifestyle channel wanted to buy my station, so I ended up selling
it.
While it is true that Classic TV programming can be gotten through the
internet by way of Roku or Apple TV, you need a good internet connection to
have a smooth viewing experience. Many areas don’t have reliable internet
service, so watching TV over-the-air is the only stress-free way to enjoy
this entertainment. Where I live, on the rural California coast, the
internet is not very good so broadcast TV is actually popular here.
Sorry for the long-winded response.

Dan, do you sense you get good ratings for the classic TV stuff?

I notice that there is a lot of Public Domain content on Tubi and similar

started to replace some of my Classic TV mpeg2 content with these higher
resolution versions in Mpeg4. I use the stand alone Cloner-Alliance box to
capture it from Roku.
