ECL syntax manual?

[Harm]

Does anyone know if some kind of document (or maybe a site) exists where all possible parms of an ECL file are described?

Some of these parms do not easily relate to an option in CCE itself.
And I've noticed several differences between ECL files created by different versions of CCE and DoCCE4U/BatchCCEWs.

:rolleyes:

I don't think there is something like you want around (maybe i'm wrong).
You can always change 1 option at time and see what changes in the ecl file, in this way you can derive all by yourself.

Good luck :)

I think the options in the ECL are fairly selfexplanatory. Post about the options you are not sure about and I'll explain.

Ok, RB (or anyone else).

Right now I'm finishing a tool for CCE that uses an Ecl file (hehe - maybe you can guess...). However, I need to know the framerate of the video. I guess I can use the .ecl key 'frame_rate_idx' for that.

I think for:
NTSC film, 23.976 fps, frame_rate_idx=1
PAL movie, 25 fps, frame_rate_idx=3
NTSC video, 29.97 fps, frame_rate_idx=4

Can you confirm this, or fill in with information?
Thanks.

I don't know if these things are true Tylo.
But if you start CCE and load the ECL file you can see to what it relates and if you change something in CCE the ECL file will be changed accordingly.
I use that technique to check the options in there.....

but it would be easier if there was a syntax manual around.... :)

[RB]

tylo, correct. Just 1-5 for each radio button from left to right.

For those really video-specific settings like frame rate and number of frames, you could also just not write them to the ECL at all. CCE figures this out from the video file automatically anyway.

[tylo]

Hmm. I've searched the CCE dialogs, but cannot find the five radio buttons (in a row?) you refer to. I only want to determine the frame rate from the frame_rate_idx (I don't need to write it).
What are the frame rates idx 2 and 5? (probably some rare rates).
Thanks again.

/EDIT: Sorry, just found them in CCE 2.67. I was looking in 2.50, but couldn't find it there (although frame_rate_idx key is saved).

[RB]

I'm talking about CCE 2.66/2.67 of course... double click a video asset, click the "Video..." button, then the small "Set" button to the right of the (grayed) frame rate edit box.

[tylo]

Hehe. Well, just to inform you what I'm doing:
Tool that does CCE OPV RoBa (as in D2SRoBa), with a multpass vbr eclfile as input.

CCERoBa -ecl <multipass VBR eclfile> -batch

Works with CCE SP 2.50, or any version + EclCCE

It estimates the Q factor (Newton-raphson method with samples) that creates the closest bitrate to the target (avg_brate), and then encodes it with OPV. Can also automatically use ReJig when slightly oversized.

Should be a hit in the DVD-Rebuilder camp :)
Already working, but I will release it this week-end most likely.

Sounds interesting Tylo..... :D

[DDogg]

tylo, holy crap, I just realized what you are actually saying! It sounds like you are doing a "bolt on" that allows ANY app that uses CCE multipass to have transparent access to all the predictive guts of D2SRoBa just by using a simple commandline that takes the multipass ECL as the argument? If so, that is awesome.

tylo,

Just left a PM for you on this subject...
