Where's FullHD 25p?

[DeeZiD]

I've recently installed Edius Pro 4.52 Trial on my PC.
I'm impressed as far as I can say:

• it's sooo fast
• absolutely stable
• all my plugins (from prodad and some VSTs) work flawlessly
• I became familar with the gui and workflow after 1 hour!

But there's one big problem for me I discovered a few moments after the first start. There isn't any 1920x1080 25p preset only 50i...

I've always used 1440x1080 25f with my old Canon A1 then switched to Sony PMW-EX1 using 1920x1080 25p which works flawlessly in Liquid, but Edius doesn't support it... :(


I really want to switch to Edius Broadcast but without support for 1920x1080 25 I can't do that.

"Support for" is a vague term.

EDIUS Braodcast definately supports your media just on a slightly different processing timeline. You will not notice any difference when editing on a timeline setup as 1920x1080 23.976p. You can work just as fast as if it was 25p timeline. The only issue here is output right? What is the required output?

[DeeZiD]

The required outputs are:
1920x1080 25psf Blu-ray (worked with PS3 and a Samsung Player)
960x540 25p for an Intranet solution ;)
720x576 25p for DVD
480x272 for low end intranet

50i is not an option for me. I switched to Progressive 3 years ago when I got a DVX100b.

That is not a Blu-ray compliant frame rate, dont know how you got it to work

[DeeZiD]

Just encoded it as 25PSF (Progessive Segmented Frame in an interlaced 50i stream).

But I don't know whether that works with other Players or if 25p works, too...
Otherwise I'll have to speed down to 24p after export.

How did you encode it? You see what you have ended up with is 50i regardless.

It is better to shoot it all in 23.976p and then you don't need to change the frame rate when you encode at all and it is still progressive.

[DeeZiD]

How did you encode it? You see what you have ended up with is 50i regardless.

Just encode an MPEG2/H264 or VC1 stream with Upper Field first instead of Progressive.

You will get an Progressive Stream with an Interlace flag then. Todays' TVs/Player ignore the flag. This works with DVB/ATSC, too

It is better to shoot it all in 23.976p and then you don't need to change the frame rate when you encode at all and it is still progressive.

I'll have to do an speedup of 4% for Pal-DVD then.
That is impossible for me because of all the voicer over...

Dennis

Are you sure that you have done this?
How did you encode the AVC and VC1 streams (what encoder) and what authoring program was used to multiplex and build the disc?

[DeeZiD]

Adobe Encore was used and accepted all.
I did use megui for h264, hcenc for mpeg2 and windows media encoder for wmv/VC1.
But the h264 and wmv streams were transcoded.

[shueardm]

Encore will not accept VC1, perhaps it transcoded it to AVC?

Regardless your video ended up being processed and is not multiplexed to the disc as 25p. So why do you need 25p timeline?

[DeeZiD]

It ended up in a 50i (segmented progressive) stream but I didn't notice any loss of quality.

Encore transcoded h264 and wmv (wmv9/vc1). But they looked good, too.

We have come to the point of all these Questions. :)

You ended up with something completely different to what you shot, you got 1920x1080 50i, which probably looks the same but you swore against interlaced. So you can shoot in 25p but you wont get progressive Blu-ray unless you ramp back the frame rate on encoding.

If there was a 25p timeline then it would be better for going to 50i (however)

[DeeZiD]

Thats true.
The whole problem is that I don't want to mess the audio while adding a 4% speedup for SD-Pal DVDs.

Or is there any Audio Time Stretch/Compress (without pitch) tool around there?


regards Dennis

[shueardm]

What you can do is use a 1280x720 25p over 50i timeline.
Then you export and use reverse pulldown to get back to 25p which is a Blu-ray legal frame rate at 1280x720- there is your Blu-ray solved but it wont be fullHD.
Then you can also do a compatible PAL DVD with the 50i as well keeping the audio problems away.

In theory, I haven't tested it myself :)

[DeeZiD]

Sounds complicated. :D
Sorry, but 1280x720 is not an option for me.

What I want are stunning fullHD pictures.
This is what the PMW-EX1 truly offers.

So I guess I'll need to produce 1920x1080 24p for Blu-ray and a Pal Speedup of 4% for PAL DVDs.
