Scenaid 1.6

[D3s7]

After a fairly large delay Scenaid 1.6 is now available in the downloads section of scenaid.com

I'm sure there are few issues w/ this build that I've not found yet however the corrections/additions warrent a release

Things w/ my RL have settled down a bit so I should be able to get fixes out a little quicker now

Fixes:
* Correction to the palette creation code (fixes the incorrect palette issue in dummy assets)
* Correction to the VTS Menu scanner - was erroring out if no menu existed in the ifo
* Correction to BoV routines, fixed a few commands in the main routine
* Correction to the no-cce file detection routine - app was erroring out occasionally when hitting a no-cce file

Additions:
* Added ability to create new D2V and AVS files with the DGIndex application suite (not included - manually install into the scenaid install directory)
* Added ability to script Pre/Post/Cell commands (option is NOT saved currently) - very useful if your removing angles or the like and are having problems w/ ifoupdate/batchifoupdate - instead just copy in the menu files using PGCEdit
* Added ability to dummy audio in a vobid demux (Use ONLY if you know for sure the audio can be dummied, no checking is done
* Additional logging/checking done on irregular assets (in the case of ARCOS or th elike) - these seem to be still causing problems

Changes:
* Changed the way the BMP creation occurs int he script, should speed up script generation
* Changed the detection of which encoder will be used and adjusts scripts accordingly
* Change to the ccedata file creation - no cce assets are no longer written to the files
* Changed interface to prevent avs playback before AVS is actually loaded

IMPORTANT NOTE: Scenaid files are now in a subfolder under you demux directory named Scenaid

Congrats on the new release

Works great, already tested it out.

Great to enable that DGDecode option, will test that in a few mins as well. This program has really become a valuable asset in any project i do.

Keep up the great work D3s7 !

[D3s7]

Thanks

really helps in VOBID demuxes....

last few I've done, there's been anywhere between 5 and 15 (yes 15) frames difference between dvd2avidg and dgdecode (decode more accurate)

d3st i was playing with your brand new scenaid 1.6, and i must say it is gorgeous!!

i was wondering a couple of questions about the builtin bitrate calc algorythm:
[list=1][*]main movie: is it possible to choose more than one VTS as main movie? i am trying to do a dvd of extras, so would be helpful for me to have 3 vts considerred as "main". otherwise the video stream scenaid considers as "main" will have too much bitrate compared to the other ones[*]video assets inside a vts: if i uncheck an asset because i know i dont want it, how does scenarist then behave? i can see the main movie bitrate raises...are they replaced by dummy videos?[/list=1]

thanks for this great tool!

(corrected some typos in last edit)

[D3s7]

1) Yes that's the plan... I just haven't got around to it yet....

2) They are replaced w/ a black still whose duration is set to the duration of the assets you unselected (split out by the cells of course)

[n1ck0s]

Sligtly off topic... Should someone use CCEdata.txt from dif4u for BatchCCEWS or files generated from SceneAid. Are there any major differences/improvements?

[influenza]

The scenaid files have more precise chapter points IIRc and they have the scenaid calculated bitrates.

[gemon]

i dont know if this could make the algorythm more complicate to develop, but could it be possible to provide some sort of 'avg bitrate classes'?
I'll make an example:
say you have 10 vts, and u want one or more to be treated as 'main' movie; the rest, though, you want them not to be considered as being re-encoded with same avg bitrate, so you could decide that 3 out of the rest are to be treated as 'intermediate'. for each vts in the various bitrate classes, you can decide the avg bitrate.
This could end up with having:

- 3 vts classified as 'intermediate' with a setup bitrate of 2500 kbps
- 6 vts classified as 'extra' with a setup bitrate of 2000 kbps
- 1 vts as 'main' movie, with avg bitrate calculated from the other two

this procedure can be more general and could allow custom number and type of avg bitrate classes...

is it feasable?

From your example you could encode the extras and the intermediate vts separately from the main movie. All you would need to do is set the ave bitrate for the intermediate vts's to 2500 or whatever you want. After it's done encoding, compile both the extras and the intermediate in Scenarist, copy the finished vob files into the video_ts folder, and then use ScenAid or DVDCalc in DIF4U to calculate the main movie bitrate from the video_ts folder. I dunno if any of this makes sense

[D3s7]

I ran a poll for awhile on the scenaid website on what people wanted to see in bitrates and no one voted

the original idea was to offer:

fixed extras - calculated main
fixed extras - % reduction in main (so all assets reduced equally)
fixed main - % reduction in extras
freeset extras - calculated main

only 1 is done right now..... i'll investigate the others if there's enough interest

Thanks for the new version... nice work.

However, I have a small problem anyway. I get an error.

Procedure Name: GenerateTrack
Module Name: ScriptGenerate

Error Number: 13
Error Description: Type mismatch
Error Source: ScenAid
Error Line: 99
Call Stack:
ScriptGenerate --> GenerateTrack
ScriptGenerate --> GenerateScriptFile
Form1 --> ExecuteBuild_Click

What does this error mean exactly? The error comes on generating tracks for VTS 1.
With the build 45, no errors.

[D3s7]

Tobi...

emailed you a new build to try

[gemon]

@D3S7 : i am actually wrighting a very little piece of code to read from the generated scenaid-ccedata.txt file and make my own modifications to the avg bitrates... only thing is that it is in JAVA, since this is the language i'm comfortable with
for the algorhytm, i am not still sure but something like this could be done:

order the VTS by frame #, this gives the idea how big an asset is; the user than can check any assets by grouping them into 'categories'. a category can have fixed bitrate or use a % of the available after calculating the fixed values.
the app then calculates and proposed the avg bitrate for the vts belonging to categories the bitrate shall be calculated.

hope this might be clear, when i have something ready i can let you know

how do I use this? I can't see anything to trigger this? unless this is automatically done when I have "open encoder automatically" enabled. right?

thanks for the reply.

[gemon]

no jarthel, it's easier...
all you have to do is download dgindex and uzip it to the scenaid folder

Gemon

[D3s7]

um.. actually it's the "Create new D2V/AVS with DGDecode" option under the "Options" menu...

requires DGIndex and DGDecode to be put in the scenaid install directory and you need to use the Scenaid bitrate calcs

[Tobii]

@ D3s7

Sorry, I could try it only now.
Yeah, it works without errors now.

Many thanks!

Whats the different between DGDecode and DVD2Avi??..

[D3s7]

DGIndex is to DVD2AVI what DGDecode is to mpeg2dec

DG = Donald Graft who picked up the project and ran w/ it as of late

DVD2AVI has known issues to drop frames during decoding - dvd2aviDG fixed that partially but still had issues

Donald changed the name of it to avoid confusion w/ DVD2AVI (which actually the orignal author picked back up and is coding again).. but for example, with "The Abyss" there were upwards of a 15frame difference on some of the vobid's between dvd2avidg and dgindex (dgindex being more accurate) - frame loss has always been an issue/problem when reauthoring movies demuxed by vobid... this option helps w/ that
