MrGruntHunter, Tintin, snafu and 10 others like this!

As you know, BluffTitler uses the MP4 encoder that comes with Windows.

There are 3 issues with this encoder:
1) It requires a lot of memory
2) It seems to require Windows 10
3) In 4K, the maximum framerate seems to be 25 fps

To solve the 1st issue, the latest version of BluffTitler (13.3.0.3, launched today!) unloads the show before starting the encoder. This frees memory that can be used by the encoder.

Taking the other issues into account, it's now possible to generate 4K MP4 videos in 25 fps on a basic Windows 10 machine!

Other new features in this latest release:
-shadows render a lot faster
-it's now possible to attach containers to sketch layers
-sketch layers automatically fix EPS files with zero length lines
-the roller coaster demo shows in the sketch folder now feature construction elements. They are automatically generated by the next version of Bixelangelo that will soon be available as a public beta.

As always, the latest version can be downloaded from the download page:

3) In 4K, the maximum framerate seems to be 25 fps

Yes, for Digital Cinema 4k (4096x2160) the max is 28,5 fps

For UHD 4K (3.840×2.160) the max. framerate is 31.7 fps

So NTSC 29,97 fps in 4k UHD (3.840×2.160) works fine on my pc for mp4 (decoder profile level 5.1)

I will test the shadow speed tonight and post it here.

Great news about the container attachment to sketch layer.
I will make some time to test the Bixangelo Beta, I think I have still some tricks up my sleeve.

I see you have poles under the rollercoaster is this a feature?
Nevermind I see that they're separate sketches from Bixangelo.

Great update and thanks to the team.

komies, 2 years ago


Yes, but there's a difference between what an encoder claims to support and what it actually does.

And yes, the construction elements are generated by Bixelangelo as separate EPS files. You can find example shows in the Media/Shows/Sketch folder.

This is great and very good. Thanks Michiel.

I just wish BT would do an MP4 in Win 7.

These 1+GB AVI files are really a bit much.

I'd like to have the option so when quality is no big deal I'd have a dinky file.

@SMSgtRod

Use a (Free) mp4 converter to convert the .avi file it's faster to upload and you can delete the big .avi afterwards.

I have windows 10 but I use the uncompressed AVI for the best quality and use Handbrake video converter set to variable at an high bitrate and 2 pass encoding at the same resolution and framerate as the original at high profile level 5.2.

2 years ago I tested my videocards and put the results in the article that is provided by the link.
These are the results from now to test the faster shadow rendering in version 13.3.0.3

GPU: ATI R9 290
Memory: 4Gb GDDR5

Blufftitler version 13.2 .....version 13.3.0.3

No shadow ....0:12 ....0:12
Shadow 0.2....0:18 ....0:12
Softness 0.5..1:18

The reference show: c:\outerspace software\blufftitler\media\shows\cubemap\ReflectiveSphere1.bt
was changed by the camera bloom.cfx on the camera layer but did not have a noticeable effect.

@komies
That's pretty much what I do.....just would be nice to avoid the extra step as Win 10 users do.

I'll most likely put Win 10 on this when Micro$oft has at least SP1 or 10.1 out. Like to make sure they have the bugs all worked out first. That philosophy is what kept me from the Vista, 2000, 8.0/8.1 and other Micro$oft land mines.

Windows10 released on 29 July 2015 (build 1507) doesn't work with "Service Packs" anymore they do now have a "yearly major feature update"

Last year was the Anniversery update (build 1607), and this year the Creators update (build 1703).

ok that explains why i have been havng issues with rendering mp4

lightads, 2 years ago


Selina, if the show has not yet been saved you are asked if you would like to do so before it's unloaded.

michiel, 2 years ago


Or simply save the show as temp or version number. Now you have the original and the modified one and can go back to either. A BT show file is rather small (about 1 kilobit per layer), my biggest is 1429 kb, so for diskspace reasons not really an issue.

komies, 2 years ago


Looks great... thank you for the new update...

Hi Michiel..Can you Explain..

"sketch layers automatically fix EPS files with zero length lines"

Some tips:

When working on a show that requires more time or experimentation use: Save show (+ all media files) and put it in a new folder that you can name appropriately and for you to easily to remember.

In this folder you can save small or large edits to the property settings and name them with successive numbers like show01, show02 etc. Now you know that the highest number is the last version, also the system date stamp gives you an indication when it was saved for the last time.

If remembering a specific effect trial among these consecutive numbered shows is still to much to remember then you can name the show with an easy reminder in the name like show02-bloom.

I believe it is a wise precaution to save shows in this manner also for unexpected issues to have a fall back. And would recommend this to everyone to make this your standard methode of operation.

You can also set the show under Settings/ General Home page so when you select Control / Home it will open the show without you having to remember it's name.

For the a specific thumbnail for youtube you can then reload the show you want it from (with the method discribed above) and export as picture. Also the 1024 and 180 pixel wide pictures for the community can now be found and made in this way.

Uncompressed Avi is still the export with the highest quality and convert it with a third party converter to a MP4 format is the way to go to get the highest quality version to put on youtube.
The export as video option MP4 is just for a fast and easy way to prepare the show for youtube upload but not the highest quality even with Settings/ High quality for rendering and Settings/options/Drivers MP4 encoding profile set to H.264 High (HiP, 100).

The unload of the show before encoding to MP4 format is a wonderful trick to save rescoures because the rendering is already done. Blufftitler doesn't have codecs of it's own or has to buy the rights (license) to use these and uses third party instead which gives freedom to the different users needs and that saves alot on the retailprice for this wonderful piece of software.

I hope that this clarifies and helps.

Dani, normally EPS files never have zero length lines. But if this happens BluffTitler automatically fixes it for you so you do not have to worry about it.

michiel, 2 years ago


How about an "Unload show before running the MP4 encoder" checkbox in the options dialog?

michiel, 2 years ago


An elegant and simple solution.
You're a real bridge builder, Michiel.
