Question about video that appears to be changed in Encore

[Jeff Pulera]

You lost me part way through with all the levels business…but here’s my take on it. If you export from Premiere as MPEG-2 DVD, then Encore will not touch the video – no trancoding – so whatever was exported from Premiere will be what is playing off the DVD. Meaning no change in levels should happen.

In fact, you should be able to Import the .m2v video you exported back into Premiere and check levels there to see what you have before going to Encore.

So figure out the correct bit rate to encode your program to so that it fits the DVD (to avoid transcode to fit) and export as MPEG-2 DVD which provides .m2v video and .wav audio. By default, Encore will leave the video alone, and audio gets transcoded to Dolby Digital.

Thanks Jeff. I was specific as to levels because it was needed to be. I will not have access to system to try the MPEG/-DVD encoding method. I’ve posted a skmelar post a Matrix site as I’m seeing 16/235 on Matrox Output as well, and Matrox does not have setup screen accessible via Encore, yet outputs video via Encore. In Premiere you have to turn on Allow Super Black And Allow Super White to allow 0-255 levels.
I hate having two possibilities with me having access to neither with certainty!!!!
That’s why I have been asking if Encore passes 0-255.

Hi Jan,

I did not mean to discount your attention to detail regarding measurement of levels at various stages, rather it is my ADHD that makes it hard for me to follow ????

As I’ve not produced video for broadcast, have never really played with or paid attention to levels – if it looks good by eyeball, that has worked for me.

But again, if you can provide a spec-legal .m2v file into Encore, it will NOT transcode it, therefore I don’t see where it would be doing anything whatsoever to levels – they are and should thus remain whatever is in the .m2v file exported from Premiere/Media Encoder. Never recommended to let Encore transcode your files – feed it what it desires.

I used to use MXO2 – I could be thinking of older RT.X2 here as well – but I recall in the Matrox output setup, there was an option to “Add 7.5 Setup” or something like that. Meaning if I were editing footage that used 7.5 IRE as the baseline rather than 0, such as MiniDV footage, then I would check that button, otherwise when viewing the Matrox output on a video display, blacks would (falsely) look washed out, which might prompt editor to want to color correct when in fact source video blacks were fine, but the output from Matrox was “off” if that makes sense.

Thanks

Curious – what video format are you actually importing into Encore then, which it transcodes?

Thanks

No sweat. Let me get to system and I’ll provide file type and try the re-render for DVD & BR. You mention.

This is not a color space conversion or setup issue. I should be able to get this info tomorrow afternoon.

As you know, a CS6 Master license allows you to install on a Desktop and a Laptop….

My Desktop has a Matrox System, Laptop does not…. In earlier post I mentioned that there was a possibility that Matrox could be part of this issue (No email from them yet).. So to Avoid the Matrox possibility…. I did today’s tests on Laptop….. To remove Matrox as a possibility of that clouding this issue…

So,, I copied the 2 files (H264 SD and HD) that shows 0-255 levels on my desktop system in Premiere —- to my laptop, and imported that into Premiere on my laptop……

I then exported that from Premiere as MPEG2-DVD or MPEG2-BR and brought each into Encore as DVD or BR project, set as first play, and then burned a DVD and BR from that footage….

The DVD and BR that was burned was played back on a Sony TV and Sony BR player… Each set for Auto format, or Y,CB,CR 422, or Y,CB, CR444, or RGB(16-235). or RGB(0-255)……
and both the DVD or BR disc created in Encore (With the video footage that shows 0-255 on Premire/Matrox system at SDI or HDSDI or HDMI output to the same Sony monitor used on the Premiere/Matrox test, where 0-255 was seen!

So, I ask again…..

Can Encore burn video with 0-255 levels, or is it limited to 16-235? I’m hoping that I’m doing something wrong….

[Jan Janowski]

Gee I wish you could edit your posts…..

Both the DVD and BR I created shows 16-235 levels from the 0-255 levels presented to it from Premiere via the MPEG2-DVD or MPEG2-BR …….

I’m hoping to faithfully create a BR (At Least) or DVD with 0-255 levels…

???????????

Later today or tomorrow at latest, will try this same approach on Desktop/Server, in the off chance that Matrox is the reason why I’m seeing 0-255 in Premiere …… I’ll render to MPEG2-DVD and MPEG2-BR as you requested and try the burn that way and test playback again….

[Jan Janowski]

I seem to be solving one question to ask another….
Desktop Server…. Render to H264BlueRay out of Premiere…. Into Encore…. Works on BR disc… Now why not on Laptop?

I have more tests to do….

[Jan Janowski]

I will put a step by step procedure for doing this… in another post at this, and Premiere’s forum, as there are procedures that need to be followed……
Watch for it!
