Exporting for Bluray

[Arex]

My source footage is 1440x1080 25p.It is an mpeg2 video(HDV tape).
Which exporter I must use in Edius 6.08 in order to convert my source
in 1920x1080? I don't want to change anything else.
Is it correct to change in 1920x1080 or is it better to make the bluray
in 1440x1080 ?
Thanks

Why 25p? HDV tape is 50i!
Change the project to 50i and you will be able to export to disk from the time line, or, Export to file using mpeg or H264
Output at the same as the project 1440 interlace is a legal Bluray format
To upscale to 1920 best to change the project to 1920
For H264 Max bit rate is 18Mb for some external Authoring programs
Mpeg Max bit rate is 40mb
I use VBR 28mb Ave 35mb Max Audio 356kb AC3 2 ch Mpeg2

The video camera is SONY FX1000E and the signal system is 1080/50i,25p.
And the recording image bit rate is ~25Mbps.As I capture progressive scan images (25p) that's why I choosed 1440x1080 25p on my project settings. O.K. I will change to 1440x1080 50i or 1920x1080 50i if I want to upscale.
According to manufacturer : " The video is processed internally as 1920x1080, but due to the bitrate limitations of the HDV format, the video is still recorded at 1440x1080. "
Can I upscale to 1920 without any problem ?
Thanks

And which must be the field order ? Upper/Lower/Progressive ?

[Bluetongue]

Hi Arex
We learn something every day, I had a look at the specs on your camera and yes it seems to do 25p
So to answer your questions
Yes you can upscale to 1920x1080 on both Export as well as changing the Project settings, 6.5 and 7 accomplish this better in theory due to the Landscos filter in the project, but I used to do it in 6 and could not really tell the difference visually
And for interlacing "UPPER" field for HD Bluray it was only a mistake made by Sony when DV was brought out that caused the upper lower field problem, but by the time it was realized it was too late
BUT even if you were using DV the DVD would have to be "Upper" field, really confusing for beginners, thank Sony
Interesting as TV has always been "Upper" field first since the beginning
Hope the guy at Sony was sacked or relegated to the packing shed

Hello Bluetongue,

First of all many thanks for taking your time and giving me all infos.
As you understand I am not a pro I just try to make DVD's with my Hi8 footage and BD with my HD footage.
If from now on I use project settings 1920 50i upper field it means that I must stop recording 25p ?
In the user guide it is written :
You can capture progressive scan images with a vertical resolution of 1,080 lines.
25 (25pSCAN) Captures 25 frames per second.
Note :The captured images are converted to 50i format and recorded on tape.
That's why till now I was recording like this
Last question please, what about the bit rate of H264 file as the bit rate of my videos is 25Mbps
Regards

Hi Arex.

If you are shooting progressive then you are best off editing in progressive. You can mix and match interlaced and progressive at the the same FPS, as Edius is great at this, but you're best off sticking with one or the other depending on the which is predominant in your source footage.

The best thing to do when you have completed your edit, is to master out a file in either progressive or interlaced, depending on your project settings. Then use this as a single clip for a new project that matches your media output. For instance. If your target output is to a medium that requires interlaced, set up a new project accordingly, then use your progressive master in that project, or interlaced master. I would suggest using the highest quality HQ settings you can get away with for your initial master project output. If you also need to down size for your media output, say going to DVD from an HD master. If you are using a version of Edius that has the Lanczos filter, use this too in the project setup.

As for H264 bitrate. Regardless of this being from Edius or a separate application, use the highest bitrate that will fit to your disk. There is no point saving space if you don't have to. This also becomes more important when dealing with low bitrate source files, like 25Mb. Remember, you are compounding the effects of compression artefacts all the way through this destructive process. So you won't be doing yourself any favours by not utilising the maximum and best of what you can achieve. This applies for any target, such as Bluray or DVD and others. Just make sure that your combined audio, video and any text streams, stay reasonably just below the legal maximum for your target medium.

Hope this helps.

Sorry I missed your reply Arex
From what I gather from the info you have given it would seem if your video was captured from tape it would be 50i at 1440x1080
As usual sony are very vague and misleading, from what i knew tape HDV spec is only 50i (25 frame Interlaced)
To check in Edius select a clip and "Right click" and select "Properties" and a box will appear giving the codec and details of the clip
I suspect it will show "Stream Type HDV" and Field Order" as "Upper Field". ALL the clips original properties are marked by "*" so you know if anything has been cahnged
If so set your project to 50i interlaced
The H264 encoding has been answered by LTVHD, I use mpeg for Bluray VBR 28mb Ave 35Max Audio 356kb Dolby AC3

Sony almost always package 25p in an interlaced 50i stream, for HDV this is certainly true and no mystery really. Panasonic do similar with their Psf. Live SDI out on a lot of cameras employ the same technique which is why devices like Samurai recorders apply 2:2 pull down with 25p sources for example.

Edius handles most of these situations automatically and monitoring can be set accordingly in settings.

A 1440*1080 50i Blu-ray is also fine, you don't need to go to full HD its your choice really.

Hi ,
In the menu of the FX1000 I can choose in Program Scan :"25pSCAN" OFF or 25. I choosed 25p because I heard that it is better image quality.
To answer to Bluetongue ,in a Project 1440x1080 50i Upper Field ,if in Device Preset I choose :
Interface :Generic HDV Video Format :1440x1080 50i Codec:MPEG TS than the properties of the captured video are : Frame Size :1440x1080 Aspect Ratio :1.3333(16:9)* Field Order :Top Field First * Stream Type : MPEG2 Video Frame Rate : 25*.
Under the same project ,if I change the Device Preset into :
Codec:Canopus HQ the properties are : Field Order : Progressive* Stream Type : Canopus HQ Frame Rate : 25*.
I am confused if I must choose a project 1440x1080 50i or 1440x1080 25p and what must be the device preset .
NakedEye says :"Sony almost always package 25p in an interlaced 50i stream "
Sony write in user guide : "The captured images are converted to 50i format and recorded on tape."
Thanks

One simple fact independent of if the original is Progressive or Interlaced the project WILL need to be set to "Interlaced" if you want to burn a Bluray direct from the timeline
If you are using a third party Authoring program you may be able to make a progressive Bluray but it is not to Specification

Bluray is Interlaced except for 1280x720 which is Progressive

The best codec for the Project is CanopusHQ efftively lossless, if you use MPEG as the project codec any rendering to get smooth playback will not be as good as the original, MPEG is a lossy codec only good for delivery

The 25P setting on the Sony will be 25FPS which is an interlace Progressive where both fields are the same picture, Edius identifies these as "Progressive"
If you are happy with the jitter on movement then continue as you are, on a still picture (one without movement) I will guarantee you will see no difference,
Where there is movement you will see a stutter on fast movement with progressive and a smooth movement with Interlaced but each field will be half the resolution for the moving object but any still part of the picture will be full resolution for each frame, there are 2 fields per Frame

I prefer Interlace for the smooth movement which is how my eye sees movement, a personal preference

Hi Bluetongue,
Next days I will do some trials following your advices.
I will check the results on my TV .
If new queries,I will be back in the forum to solve ,an perhaps helping other people.
Many thanks for your support.

Hi Arex!

If you are just making family videos and don't know how to shoot 24/25p then set your SONY camera to to 1080/50i and forget PSCAN the camera offers you. In Edius your project can be 1440x1080/50i or 1920x1080/50i and burning to Blu-ray will be simple as will down rezing the project settings for DVD.
