Optimize loop trought layer export

[jeremyb]

Hi,

I try to optimize part of code, that currently export frame by frame on each visible layer. But i've got some trouble with loop 'FOR image = 1 TO 50'

Code: Select all

// COLLECT DATA FROM ARGS 
tv_ReadUserString VfxConfig ExportPath
exportPath = '"'result'"'

tv_ReadUserString VfxConfig PlayblastPath
playblastPath = '"'result'"'

tv_ReadUserString VfxConfig Episode
episodeNum = result

tv_ReadUserString VfxConfig Sequence
sequenceNum = result

tv_ReadUserString VfxConfig Shot
shotNum = result

tv_ReadUserString VfxConfig Version
versionNum = result

// COLLECT DATA FROM TVPAINT FILE
tv_FirstImage
startingFrame = result
tv_LastImage
LastImage = result

tv_Background "NONE"
tv_SaveMode "PNG" "b32"
tv_AlphaSaveMode NoPreMultiply

layerRun = 1
layerCount = 0
WHILE layerRun == 1
    tv_LayerGetID layerCount
    layerID = result
    IF (CMP(layerID,"NONE") != 0)
        layerRun = 0
    ELSE
        tv_LayerSet layerID
        tv_LayerInfo
        PARSE result layerDisplay layerPosition layerOpacity layerName layerType layerStart layerEnd layerPrelighttable layerPostlighttable
        IF (CMP(layerDisplay,"OFF") == 0) && (CMP(layerName,"playblast") == 0)
            tv_layerpostbehavior layerID
            endBehavior=result
            IF (CMP(endBehavior, "NONE") == 1)
                endingFrame=imageEnd
            ELSE
                endingFrame=LastImage
            END
            lyrExportPath = CONCAT(exportPath,layerName)
            lyrExportPathFormat = '"'lyrExportPath'"'
            tv_WriteTextFile "mkdir" lyrExportPathFormat
            FOR CurrentImage = startingFrame TO endingFrame
                currentReelImage = CurrentImage+1000
                tv_layerImage CurrentImage
                layerFileName = episodeNum"_"sequenceNum"_"shotNum"-"layerName"_"currentReelImage".png"
                exportFullPath = CONCAT(lyrExportPathFormat,layerFileName)
                exportFullPathFormat = '"'exportFullPath'"'
                tv_LockDisplay "Exporting... (layer "layerName", image "currentReelImage" )"
                tv_saveimage exportFullPathFormat
                tv_UnLockDisplay
            END
        END
        layerCount = layerCount + 1
    END
END

This line make some error, script dosen't do anything and i don't know if is the good syntax ?

Code: Select all

FOR CurrentImage = startingFrame TO endingFrame

By the way, on which language GEORGE is based ?

regards

George is not a language. George is just a set of commands, that the current version of TVPaint can understand.

try using another variable name in the FOR/NEXT loop, like CurImage. The interpreter might be getting confused.

yep, i've allready change some 'Common' var...but still here

j.

tested your code (without any changes except commented out "// tv_saveimage exportFullPathFormat line") by putting a tv_warn message inside FOR/NEXT loop... and the loop works for me...

sven

[jeremyb]

hum, yes !
that's a problem

Code: Select all

CONCAT(exportPath,layerName)

should be the same as : ? right ?

Code: Select all

lyrExportPath = exportPath"\"layerName"\"

so, why is blocking when i want create directory with that path ?

Code: Select all

tv_WriteTextFile "mkdir" '"'lyrExportPath'"'

[jeremyb]

So, to rebuild filepath i need to remove ' " ' from result

Code: Select all

tv_ReadUserString VfxConfig ExportPath
exportPath = result

note:
cmd line output from ExportPath : \\server\project\version\

So after, i can re-create path

Code: Select all

layerPathCreate = exportLayerPath'\'layerName'\'

but, tv_Warn doesn't catch layerPathCreate if i wan't to print path, to see if iam correct...
any idea ?

[jeremyb]

Ok, after testing all formatting string, i think there is an issue with UNC path...

if my exportLayerPath result is UNC, i've got error with : tv_WriteTextFile "mkdir"
if i change UNC with a mapper drive, all working good.

Code: Select all

layerPathCreate = '"'exportLayerPath'\'layerName'"'
tv_WriteTextFile "mkdir" layerPathCreate

Apart from that, I don't see where I could have made a mistake

[jeremyb]

After checking, everything, really everything...it was the installation of TVpaint that was not good.
Our sys admin, has overridden the installation since 10.0.3.

With a fresh install, it's good !

[jeremyb]

i'm back again

I thought they was a problem with tv_lockdisplay, so i remove tv_lockdisplay and tv_unlockdisplay.
The issue, came back !

And if i re-write tv_lockdisplay and tv_unlockdisplay the issue still !

I'm really stuck, and I don't understand why...

Find if we are a tvpaint support on our contract, then i call later.

[jeremyb]

can there be problems if ffmpeg is already installed on the machine?
or LVA filter

I'm trying to find out, because apparently...I'm the only one with this problem

Hmm, TVPaint uses FFmpeg to read and export mp4/mov/mkv, so there's a chance that a conflict can happen when trying to export files.
However the dll/dilyb/so used by TVPaint are in the software's folder, so I don't know if having another version of FFmpeg is the culprit here.
Have you tried on a computer without FFmpeg?

[jeremyb]

Yes I had also tried without ffmpeg, the problem remains the same.
After trying everything, and I spent a while there. I decided to switch part of the workflow to Blender.
