What are the episodes GLM vs InternetArchive?

[LazyPooky]

I had it on my old computer but not this one. VLC told me the FPS of a HEVC ep I downloaded but not the rest of them, figured it was something off with the ep files.

I just installed MediaInfo from your link, thanks, and it says 29.970 FPS. So I guess the 1080p ones Pooky gave me were 29.970. I wonder where these 24 FPS ones came from. Are they any better? What are they called in comparison to these? Mine say Kidstream when I play them.

Yes I explained the Kidstream USA videos in the other thread, they're 29.97 fps so with doubled frames.

The 24 fps are originally came from Amazon download 25 fps, which were speed up to that frame rate and not using doubled frames. So it was easy to slow down to 24 fps with the help of ffmpeg. The quality should not be that different.

The episodes I choose were the best ones and was originally a mix of different dubs, like English, Hungarian episodes. I checked every episode and chose the best one because sometimes I noticed one or more bad frames, or mixed when both episode had some bad frames.

I thought Kidstream and Amazon referred to the same thing. OK so they're different. I am just wondering if there is any point to me downloading all the 24 FPS ones and adding sound if I already have the Kidstream ones.

"The quality should not be that different." Sounds like there isn't.

When you say "the best ones" do you mean from Amazon, or from Amazon and from Kidstream combined? I don't know what Kidstream is. I would be surprised if Amazon had Hungarian dubs.

Nope no audio with those. Separate download https://video.getlazymedia.com/items...audio-season-2

For stitching the audio back (remuxing) https://video.getlazymedia.com/items...uction-english

That way you can create your own language dub video, or stick with the original English.

Ah ok thanks. Now the big question is whether I should do all that if I already have the Kidstream ones.

When I look up Kidstream I see this. Weird there was/is an Amazon set that is not from Kidstream. I wonder what it's from.

Sorry my mistake !! The episodes came from HBOmax.

Well, if you don't care about the speed and frame rate of the episodes then there is no point in downloading the 24 fps episodes. Quality is about the same. It's hard to compare but from the individual frames I can't see much difference. The 24 fps episodes are made for the dubs to fit all to one batch of episodes.

The best downloaded episode. I have episodes from each dub on HBOmax, and I used the English one as much as I could but sometimes there was a bad frame so I used another dub episode, or switched bad frames for the good frames.

I used FFMPEG to extract all frames like they already were in: YUV /4:2:0 /8 bits - so no quality loss. Checked the frames in a second extract with PNG-frame-images, which I used as reference, because there is no way to view YUV images. So you need to have the PNG-images to watch them.

I removed the black start and end frames from the YUV extract and replace bad frames if necessary, and added the frame together again in 24 fps (24000/1001 actually or 23.976 fps).

The 24 fps episodes (HBOmax) are made/uploaded for the different language dubs to fit all to one batch of episodes. If you only want English and don't care about the frame rate, you can stick to the Kidstream USA (Amazon) episodes.

i was thinking of ripping every lazytown episode and song to dvd/blu-ray because they're so impossible to store.

That's what I want to do but probably need to figure out how to fit them on less disks. I don't want lazytown to fall victim to computer (or user!) issues like some of my other data has. I burned blu-rays and edited video in the past but need to learn more about disk burning, compression, etc. I would rather things stay uncompressed but I am guessing that would require lots of disks. Luckily I have server and hard drive space too.

for starters you could use 50gb blu-rays or if they're too expensive use an excessive amount of dual layer dvd. i have accepted i cant use glm's episodes because i'd burn through so many discs so I'm planning to use the truenorth uploads on the internet archive, just so i can put all the episodes on 1 disc.

i plan to put them on 4 discs

1. episodes and promos
2. songs and music videos
3. interviews and articles, bts
4. live shows and all the stuff on the first 3 discs but for the live shows

Hard-disk drives usually are more reliable than burning on CDr or DVDr. I have data on a backup hard-disk that's over 15 years old and still good, half my CDr collection rotted away during that time. Maybe they're better quality these days but still easy to damage if you don't watch out.

All episodes fit on a 250 to 500GB (external)-hard-disk. These HDD are not expensive now.

1.5GB x 77 episodes = 115GB
3.5GB x 77 episodes = 270GB

MediaInfo says HBOMax one is 19.5 Mb/s while Kidstream is 12.3 MB/s. HBOMax one is 3.5 GB while Kidstream one is 2.1 GB.

But despite the bit rate and file size differences you say there's no video quality difference?

Opening them with video players the Kidstream one is 24:04 while the HBOMax one is 24:39. That seems odd too. Shouldn't they be the same? Speed would be a little faster for 29.97 but it has more frames so should be the same total run time. If run time is the same I would expect the sound dubs to work for both.

Clearly I don't understand much about all this.

I notice the HBOMax ones have much higher bit rate.

Kidstream used the speedup 25 fps episode (23:40 without the Kidstream intro) and made that 29.97 fps by adding duplicate frames. The true speed (24 fps) is 24:39 - so if you slow down the 25 fps episodes:

If you fit 25 frames in one second, instead of 24 frames, the video runs faster. All frames are a bit shorter and move faster to fit in that one second. Most people don't hear/see the difference. But if you fit 30 frames in one second, instead of 24 frames, the speed goes extremely faster and that doesn't sound right, everyone hears/sees that. So they used duplicate frames. Still 30 frames in a second but 6 frames are double so the speed is the same as the 24 fps (or 5 frames double with the speed of a 25 fps episode). Every 4th or 5th frame has a duplicate, still the frames in between run quite a little faster - somehow it's hardly noticeable, that's the weird thing.

I thought the 25 FPS had blended frames and were terrible for frame by frame screenshots? Does Kidstream have blended frames? I don't have any software that can open HD video files and do frame by frame other than players like VLC.

No thoughts about the bit rate difference?

Some episode renders from sources have blended frames but I don't use those episodes of course. HBOmax 25 fps has no blended frames, it's just speed-up. Kidstream uses duplicate frames to reach 30 fps. No blended frames either.

Don't focus on Bitrate too much. All the HQ sources have about the same bit rate. I only rendered the 24 fps in a higher bit rate to avoid losses in quality.

the original source for the 24 fps were the HBOmax episodes 25 fps, and you can compare that with the Kidstream episodes 30 fps:

HBOmax (25 fps) - bit rate 8.25 Mb/s (max 12.4 Mb/s)
1. Kidstream (30 fps) - bit rate 10 Mb/s (max 19 Mb/s) AVC cbr
2. Kidstream (30 fps) - bit rate 12-13 Mb/s (max 25 mb/s) AVC vbr
3. Kidstream (30 fps) - bit rate 8 Mb/s (max 14 Mb/s) HEVC vbr

You see that the second Kidstream source is the best because of the highest bit rate and it's a variable bit rate (vbr) instead of constant bit rate (cbr). So less compression and less losses in quality. The only problem here was the duplicate frames. That's why I could not use the episodes. Instead I used the HBOmax, with less bit rate though (less quality so to say).


My 24 fps episodes render has bit rate 19.5 Mb/s (max 50 Mb/s) but that doesn't say anything about the quality because the source had much lower bit rate (8.25 Mb/s) which was the quality limitation.

Now, I don't know what source Kidstream used to render the episodes in 30 fps but it could be also a much lower bit rate. The bit rate of this Kidstream 30 fps has less meaning without knowing the source. We just assume it would be about the same.


Kidstream 3 source used a different codec (HEVC). This codec can compress videos more, with the same quality at a lower bit rate than AVC. Only useful for streaming services. Not really interesting for us.


10 years ago when we got the first HD episodes, the bit rate was only 5 Mb/s so it's getting better.
