Hey Walter,

If you get a chance, could you answer my last question?

Or anybody else for that matter.

Thanks!

[Jerry Smith]

I’m still using 2014.3 mostly. I guess I’m out of luck.

[Jerry Smith]

@ Richard, I’m sorry, I don’t follow. Can you elaborate a bit?

@ Walter, does the presence of Scopes mean I don’t have to do your first procedure?

Thanks.

[Jerry Smith]

Thanks Walter, I knew you were going to say that they are virtually the same. But the thing is, I never use Quick TIme. I never leave Adobe programs. So, are you saying that AE is assuming that it is Rec 709?

[Jerry Smith]

Actually, MJPEG has 4:4:4 that I can use. Albeit at 1280×720 only.

The file sizes are really nice.

But I’d like to up the quality. Do you guys know if I can make it near lossless?

[Jerry Smith]

Yes Tero, I know a bit about bit rate. But that was a nice list for a dummy like me.

Your comment about the color was interesting. I’ve been wondering whether there is some shade of red that is least noticeable. The BBC’s lower third has the bright red for the logo, but they use a much more purplish red for most of it. That seems to mitigate the problem. I went right up to the TV today and the logo does look quite crappy, while the rest looks noticeably better albeit far from perfect.

With text you get the whole range at the edges ranging from white to the red I guess normally blended.

I’m a bit shocked that there is no codec that will get me out of this jam.

It’s really frustrating too because the amount of information in my stuff is minimal. Many many frames are repeated 100 times. But the compressors don’t take advantage of that.

Suppose you had a video of single stop sign drawn in illustrator over 5 minutes + audio. It seems you’d have to take on all these ugly fringing effects and still have a file size proportional to the time.

I would have thought the codec geniuses would have done better by text. Not happy about this.

[Jerry Smith]

The JPEG2000 was interesting to try. The file size is still very big and basically the same as the Animation codec that I’ve been using. Results were quite nice. I could have tried to drop the quality a bunch more.

The problem though is that it doesn’t play in the iPhone’s native AVPlayer.

[Jerry Smith]

It doesn’t seem that there is any format that people actually consume that doesn’t subsample chroma information. I’m looking at this list. Is that true??

https://en.wikipedia.org/wiki/Bit_rate#Video

16 kbit/s – videophone quality (minimum necessary for a consumer-acceptable “talking head” picture using various video compression schemes)
128–384 kbit/s – business-oriented videoconferencing quality using video compression
400 kbit/s YouTube 240p videos (using H.264)[20]
750 kbit/s YouTube 360p videos (using H.264)[20]
1 Mbit/s YouTube 480p videos (using H.264)[20]
1.15 Mbit/s max – VCD quality (using MPEG1 compression)[21]
2.5 Mbit/s YouTube 720p videos (using H.264)[20]
3.5 Mbit/s typ – Standard-definition television quality (with bit-rate reduction from MPEG-2 compression)
3.8 Mbit/s YouTube 720p (at 60fps mode) videos (using H.264)[20]
4.5 Mbit/s YouTube 1080p videos (using H.264)[20]
6.8 Mbit/s YouTube 1080p (at 60 fps mode) videos (using H.264)[20]
9.8 Mbit/s max – DVD (using MPEG2 compression)[22]
8 to 15 Mbit/s typ – HDTV quality (with bit-rate reduction from MPEG-4 AVC compression)
19 Mbit/s approximate – HDV 720p (using MPEG2 compression)[23]
24 Mbit/s max – AVCHD (using MPEG4 AVC compression)[24]
25 Mbit/s approximate – HDV 1080i (using MPEG2 compression)[23]
29.4 Mbit/s max – HD DVD
40 Mbit/s max – 1080p Blu-ray Disc (using MPEG2, MPEG4 AVC or VC-1 compression)[25]

So colored text will always suffer???

[Jerry Smith]

Is there a trick or work around for h.264? If I were willing to settle for half resolution, could I get rid of the shadow? I could maybe even scale up the project in AE to 3840×2160 first. That would give me potentially a factor of 4 vertically and horizontally to play with.

Thanks

[Jerry Smith]

Oops.

Problem solved. I had some stray CSS causing problems.
