Compressor fccHandler ID's

[ExperimentalAnimations]

From http://www.virtualdub.org/docs/vdscript.txt

int GetCompression(int var);

Retrieves a variable for the currently selected compressor:

var=0 Returns the fccHandler ID for the compressor.
var=1 Returns the maximum keyframe interval.
var=2 Returns the quality factor (0-10000).
var=3 Returns the data rate (0=no data rate).


Its formatted in hex, how do i find them? Im looking for lagarith and huffyyuv in particular.

You'll have to convert the hex to string. It's likely just ASCII.

Lagarith = LAGS

HuffYUV = HFYU

Thanks but im trying to modify this code

REM echo VirtualDub.video.SetCompression^(0x636c6c63,0,1000 0,0^);

Apparenty 0x636c6c63 is the ID for uncompressed. It seems its not hex, im not sure what it is.

[Guest]

That's Canopus LossLess v.1.10 CE (CLLC).

You can specify a string:

SetCompression("HFYU",0,10000,0)

Open Character Map : Start > Accessories > System Tools > Character Map .. Select the "Terminal" font and for each letter you get its hex value 0x63 = c 06c = lowercase L ... so it's "cllc"

Thanks for the tip. Ive tried both 4 letter in quotes, and hex and they always default to uncompressed. I dont get why this isnt working.

[ExperimentalAnimations]

I left it out entirely and its still is doing the same.

[ExperimentalAnimations]

In case anyones wondering, this is from a IVTC script someone wrote, i was just trying to make it more manageable.

Edit: its a .bat file. I got lagarith 1320, vdub 1.9.10, avisynth 2.5.7.


for %%f IN (*.mts) DO (
echo directshowsource^("%%f"^).AssumeTFF^(^).SeparateFi elds^(^) > %%~nf.avs
echo Assert^(width^(^) == 1920, "Not a 1080p24 source"^) >> %%~nf.avs
echo x0 = selectevery^(10, 0,1^).Weave^(^) >> %%~nf.avs
echo x1 = selectevery^(10, 2,3^).Weave^(^) >> %%~nf.avs

echo x3 = selectevery^(10, 8,9^).Weave^(^) >> %%~nf.avs

echo Interleave^(x0,x1,x2,x3^) >> %%~nf.avs
)

In your AVS file loop, your SetCompression line is commented out and specifies "clls".

[ExperimentalAnimations]

Yes, that was the default script. I dont see any // for comments, where do you see comments?

[Guest]

Take away the REM at the beginning of the line. It stands for REMARK and is used as a comment in batch files.

[ExperimentalAnimations]

Ok, still doing uncompressed. I tried "LAGS" and it crashed, then i did the hex version and nothing. I also did the hex of "Lags", uncompressed.

Edit: Tried just "Lags" and behold i got a compressed file, however i cant get any programs to recognize it as such.

[Guest]

You have to give us the script after you change it. We can't guess what you did.

[ExperimentalAnimations]

Oh, here it is

for %%f IN (*.mts) DO (
echo directshowsource^("%%f"^).AssumeTFF^(^).SeparateFi elds^(^) > %%~nf.avs
echo Assert^(width^(^) == 1920, "Not a 1080p24 source"^) >> %%~nf.avs
echo x0 = selectevery^(10, 0,1^).Weave^(^) >> %%~nf.avs
echo x1 = selectevery^(10, 2,3^).Weave^(^) >> %%~nf.avs
echo x2 = selectevery^(10, 5,6^).Weave^(^) >> %%~nf.avs
echo x3 = selectevery^(10, 8,9^).Weave^(^) >> %%~nf.avs

echo Interleave^(x0,x1,x2,x3^) >> %%~nf.avs
)

for %%f IN (*.avs) DO (
echo VirtualDub.Open^("%%f"^); > %%~nf.script
echo VirtualDub.video.SetCompression^("Lags",0,10000,0^); >> %%~nf.script
echo VirtualDub.video.SetOutputFormat^(11^); >> %%~nf.script
echo VirtualDub.SaveAVI^("%%~nf.avi"^); >> %%~nf.script
echo VirtualDub.Close^(^); >> %%~nf.script
)

for %%f IN (*.script) DO (
"C:\Program Files\VirtualDub\vdub.exe" /min /x /s %%~ff
)

for %%f IN (*.script) DO (
del /Q %%f
)

for %%f IN (*.avs) DO (
del /Q %%f
)

You're being really imprecise. You said you tried "LAGS" but you give a script with "Lags".

Sorry, but I cannot work like that. Maybe someone else can help.

Last idea: Open VirtualDub. Set the Lagarith codec. Then save processing settings. Open the settings file and see what fourcc VirtualDub used.

[Guest]

Edit: Tried just "Lags" and behold i got a compressed file, however i cant get any programs to recognize it as such. Open it in VirtualDub. Is it OK?

[ExperimentalAnimations]

Yes, i said i tried "LAGS" then the hex of that, then i tried the hex of "Lags", then i did just "Lags" and it worked.

Checked the process settings, and it gives me "sgal". Ah, ok, ive seen that before in AE. For some reason it will flip from time to time.

It will open and work fine, its just that nothing recognizes it as lag, so its anyones guess if lagarith itself will.

[Guest]

That's weird. I confirm it gets saved as "sgaL"!

I suggest taking this to the VirtualDub forum:

Oh ok, thanks for the help.

[Guest]

I think I know what's going on.

VirtualDub stores the 4 character string as an int and not an array of 4 characters. So because of the byte ordering of ints, it appears reversed. If you just use the string representation you should be fine. So use "Lags" in your batch file. Other applications should have noproblem with the resulting encoded file.
