Not sure where I got the 48,000kbps.... I was intending to refer to the video, but I still got it wrong. (see attached screen capture)
It would appear you got it from the "Audio sample rate." 48kHz (the same as 48,000 Hz) means that the original analog audio was sampled - to convert it to digital format - 48,000 times per second. That is the standard audio sampling rate for DSLR cameras that support video.
Your total bitrate (video + audio) is about 35,000 kbps (kilobits per second). So any output from PTE at 5,500 kbps will degrade the quality of the original. But whether you or anyone else will notice that degradation in either the audio or the video will depend on many factors including how good your sight and hearing is and how far away from the screen you are sitting.
As a very, very rough rule-of-thumb (because it depends on many things) a full HD video (1920x1080 resolutiion) should typically be in the range 10,000 kbps to 40,000 kbps for optimal playback quality.

My camera outputs video at 48,000kpbs
Hi Jim,
I'd be very surprised if it does. I think you're referring here to the audio sampling rate (which is very different from the overall bitrate).
As Lin said there's no "one-size-fits-all" for bitrate. If you can tell us a bit more about your shows and how they're delievred for viewing we can probably give you some pointers.

The color managed image looks much better on my systems.

A few years ago I wrote what became an appendix in the unofficial PTE manual about HD video production. The world and technologies have moved on since then and 4K video production is fast becoming available (PTE now supports it). If anyone is interested I'm willing to update it to today's technology landscape and Igor can, if he wants, add it to the PTE 8 manual/online help.
-
Ultra HD should be future proof for a while. I am already working in 4K for my next project. But 8K is the latest standard so there will likely come a day when 4K is considered old technology.
The problem with 4K is how to deliver it in a way that, like Barry said, gives smooth playback. Obviously the cinema distribution of 4K has solved that problem but it's still a few years away in my opinion for consumers.

While the format aspect ratio of DVD video is different between PAL and NTSC, so is the pixel aspect ratio. So it is possible to author video that will play back at either 4:3 or 16:9 (the two most common formats) in both PAL and NTSC formats - just like commercial DVDs. PTE will take care of the format and pixel aspect ratio requirements behind the scenes as long as you have all the settings correct.
To burn to Blu-ray disk in Blu-ray video format you will need another program. There are many out there that vary widely in price and capability but, yes, it should be very straightforward once you have a .mp4 file. H.264 is not exactly the same as MP4. MP4 is a video container standard while H.264 is a codec.

Potwnc,
That is kind of what I mean. BB asked a question - you are querying apossible bug. Should your query not be in the Bugs section??
DG
OK I posted in the bug reports forum.
-
Is it just me or has this thread strayed off topic?
DG
Not really. Barry (the original poster) asked what the 2 options did and thedom answered:
1 corresponds to the option "number of slides for beginning"
3 corresponds to the option "number of slides for the end"
The number of slides choosed for those parts by the creator of the Style is a fixed number whatever the end user makes.
But based on my testing the real answer is that they either do what the style creator intended them to do (thedom's answer) or they do nothing at all. For example I can apply the crystal ball style to 2 images and then after PTE creates 4 slides I can simply delete slides 1 and 4 from the timeline. In that case the real number of slides required for the beginning and the end is 0 and not, as I think thedom intended, 1. This may be a bug in PTE but since I'm still finding a lot of things about styles to be counter-intuitive I don't know if it is a bug or not.
-
Potwnc, I just checked the Style with V8 beta 5 and it works Ok for me, whatever the number of slides (=images) selected.
Unfortunately, I have no idea of what you could do wrong.
A Style is very easy to use. You only have to respect the minimum number of slides (=images) to apply it to. It's two in th case of the Crystal Ball Style.
Could you please try with beta 5 and post the error messages you get.
Thanks.
I installed beta 5 and it works the same way as beta 4. I don't get an error message but it seems odd to me that PTE can tell me that a style needs 2 images and then later tell me that the same style needs 4 (or any other number) of images. If it said that it needed "a multiple of" 2 images that would make sense to me.
-
I downloaded the crystal ball style and imported it. When I try to apply it to 2 slides it says that it needs 2 images and that I used 2 images. Then it creates 4 slides using one of the images twice (at the beginning) and creates a blank slide as the 4th slide. When I try to apply it to 4 slides it says that it needs 4 images and that I used 4 images. This time it creates 6 slides and, again, uses one of the images twice (at the beginning) and creates a blank slide as the 6th slide. In both cases the first slide does not actually include the image that appears as the name of the slide in the timeline.
This could be:
My total failure to understand the new "Slide Style" feature;
a bug in PTE (I'm using beta 4);
a bug in the style itself (which I doubt as thedom is one of the best PTE experts in the world).
So I posted this here instead of reporting it as a bug. Either way it is very confusing to try to apply a style in one case and see that it needs 2 images and in another case and see that it needs 4 images and in both cases to see it create neither 2 nor 4 images.
Is anyone else finding all of this confusing?

I wonder whether the terminology is the cause of so many different opinions being expressed here about Slide Styles? If I think of an object (as in Objects and Animation) then I can place objects (text, images, videos etc.)on a slide and animate them in various ways (pan, zoom, rotation, blur, opacity etc.). If I animate an object to, for example, begin blurred and zoomed out then zoom in and rotate fast at first then more slowly as it finally stops rotating and zooming and is now fully in focus haven't I created a style that I may want to apply in the future? The reason I choose this example is because everyone is familiar with it. It was used for the longest time (and still is sometimes) in movies when the director wanted to tell part of the story by showing a front-page newspaper headline. I think of this as an "Animation Style" not a "Slide Style." A slide is something very specific in PTE and I may not always want to apply one of my "Animation Styles" to a slide. It makes more sense to me to want to apply an "Animation Style" to one or more objects in the O&A window even if the only object is the main slide itself.
Am I totally missing what WnSoft has in mind with Styles?

Slide styles are not meant for being applied to existing, nicely programmed slides
Why not?
I have exactly the same question! Why not? For example I have an old show that is already "existing, nicely programmed slides" and all I want to do is, say, change some of the zooms to begin their zoom blurred and come into focus at the end of their zoom. That, to me, is a style. Why can't I define a style that says: "begin blurred and end with no blur" and then apply that style to some of the "existing, nicely programmed slides" in my old show?
-
I guess the problem I'm having - one of them because I'm having many - is that when I first try to create my style, PTE is suggesting that the number of slides for the beginning (and the end) is -1 (minus 1). I'm no dummy when it comes to mathematics but how can there be -1 slide at the beginning and at the end?
I can apply DG's DaveGee_Oddi_Ex.ptestyle to 4 slides in my project and, as expected, it turns those 4 slides into 1 slide when I apply it. But where are these parent/child relationships and frames coming from? Obviously I need to create those before I create my style but I have no idea how to do that.
-
OK here's the project and the .ptestyle it uses. This was made by creating a new project from scratch. It recognizes that the style requires 2 slides but it plays them one after the other instead of combined into 1 slide. When I posted last I was trying to apply this same style to 2 slides in a project created in version 7.5 so maybe that's the problem - we can't apply styles to slides in shows created in a previous version?
-
I think I understand this but I'm obviously doing something wrong... As a next step I created a style that requires 2 images (of the 4 I'll eventually need). But now when I put my 2 images on the timeline as slides, select them and try to apply this style it says that the style needs 2 images, you used one image. Any ideas anyone?
-
Does anyone know if I can apply a slide style to images in the O&A window? Let me explain what I'm trying to do. My show is 1920x1080. My slide is a blank, black slide (also 1920x1080). In the O&A window I have 4 images, each a quarter the size of the screen (i.e., 960x540 pixels) laid out edge-to-edge (this is sometimes known as a "Brady Bunch" layout). So if my 4 images just contain the letters A, B, C and D it looks like this:
AB
DC
I've defined a very simple style that starts with a slide at 50% original size, 50% opacity and blurred. It zooms to 100% original size, 100% opacity and no blur. It then goes back to its starting point. I want to apply this style to each of the 4 images in the O&A window so that each image is animated independently of the other images according to this style.
I can't figure out how to do this. I hope it's possible otherwise this is a very big limitation for a lot of the kind of things I do.

Thanks to everyone who posted their reply and their additional insights on this topic. I spent the last few hours doing some further research and experiments and I now have a workaround. I can finally import PTE's virtual .avi files into Sony Vegas Pro 64-bit version (at least Vegas version 10 and PTE 8 beta 3 - I haven't tested any other combinations).
On a side note: this workaround also lets me import raw, uncompressed .avi files into Sony Vegas Pro 64-bit version. But a word of caution here - a 9-second slideshow at 1920x1080x24p created a 1GB (yes gigabyte) file using PTE 8 beta 3! Scale that up to 4K video, raw, uncompressed and a slideshow of, say, just 10 minutes and I can only imagine how powerful a computer you would need to render it!
To answer Tom's last post: Yes one of my aims in setting up my workflow is to encode only once as each re-encode or transcode degrades quality. But another aim is to be able to do things that PTE can't currently do - like video stabilization, color grading etc. in 3rd party software (in my case Sony Vegas Pro). This is best done with source material that has never been encoded in the first place. Which is why I think a big next step for PTE is to be able to work with TIFF (or preferably RAW) images. But that's another topic that doesn't belong in this topic or this forum.

Perhaps all we need is a 64-bit version of the PTE codec. Igor, is that possible or will we have to wait for the native 64-bit PTE itself?
-
============================
Dave,
Thanks for the info. I never would have found it. But I also see that you can type in less than 50%. The video gets a little choppy but it is probably due to the frame rate. Maybe if a video clip is shot at a higher frame rate, a less-than 50% might look better. Not sure yet.
Gary
If anyone has an iPhone 5S they can shoot at 120fps. 20% of that (24fps) should look decent.
-
I know it's not an ideal solution because of the very large file size but does the full frame uncompressed custom avi work? Just curious. I have noticed some apps will take the tmp avi file and others do not.
Thanks,Tom
I can't get PTE to render in full uncompressed custom avi format except for very short shows - it dies on me I guess because the files are so large. I'll see if v8 beta 2 can open a short show but even if it can that's not much use to me.
-
This is not another negative post about version 8. For what it's worth I think it looks great based on what I've seen so far. But I must say I'm disappointed that I still can't open virtual AVI files in the 64-bit version of Sony Vegas Pro. Igor posted a long time ago that he would try to address this but, sadly, version 8 (beta 2) suffers from the same problem. I realize that a native 64-bit PTE is probably quite a few years away but if, like me, you do your final video rendering in 3rd party software like Vegas (and there are good reasons to) you'll know that the rest of the world of video software is rapidly going to 64-bit. I can't upgrade to the latest version and also continue to use PTE because Vegas is now (version 12) 64-bit only. While I have the 32-bit version 10 it can't handle long productions in 4K resolution.

Thanks Lin,
Now I get it!
-
I must be missing something about the blur style. There is blur zoom in and blur zoom out but what if I want to just blur without zooming? The style has only 1 image so that must be the image that blurs. Maybe I don't understand what it means to blur an image but what I'm seeing is very different from what I expected from this new feature.
-
Indeed they are, Lin. I was quite impressed last Monday by the new Apple Mac Pro. I'm sure anyone who does the kind of things we do will want one (needing one is a different matter...) A high-end professionally configured one with all the external peripherals will probably cost about $25,000 when they become available later this year. I read one review that compared it to the Cray I supercomputer from 1976. Back then it cost almost $9 Million and was 47,000 times slower than the new Mac Pro!
Do you create Virtual AVI or Custom AVI?
in General Discussion
Posted
I create virtual AVI output mainly.
Please, please, please don't remove virtual AVI output.
I also sometimes produce AVI with a custom codec, but as long as virtual AVI output is not removed I can achieve the same thing with third-party video editing software.
