Firstly, try VirtualDub 1.8. It's unstable, but has better colourspace support. Secondly, in Lagarith's config, select RGBA as the output.

Hi, thanks for the reply.
I tried VirtualDub 1.8.0 with the same results as 1.7.8. It still says Dummy Alpha Channel in the color depth options for 32 bit RGB. And I have the mode set to RGBA in the Lagarith configuration. I suppose I will have to look writing an app to compress my own avi from images or uncompressed avi with Lagarith. |

Avisynth supports RGBA and you could use avs2avi to encode it to lagarith, in that very same thread you can also find a GUI for it (avs2avidrop).
It just occurred to me, did you set virtualdub to work in fast processing mode? |

I have often created lagarith files containing alpha channel with Adobe After Effects or Adobe Premiere. I think free trial versions may be available. Avisynth can also generate video with alpha channel like [P]ako said, and thats probably the easier way to just test it.

I have noticed that the Lagarith codec has been updated to version 1.3.18! Thanks for the updates Ben Greenwood

So, I'm very annoyed by the Adobe video apps (I've seen this in Premiere Pro and After Effects CS3) inabilty to actually take settings with Lagarith. I can choose the options like normal, but when I close the dialog and go back, it's always RGB without multithreading, and regardless of what I set the options to, the output is always RGB single-threaded.
Anyone know of any workaround for this? A reg key I can set for default behavior or something? |

I have been trying out the newest version of MLC and the newest Lagarith, and Lagarith has been my winner!
Capturing from a NTSC Laserdisc at 29.97 720x480 YV12 using virtualvcr and through S-Video to S-Video via BT878a based board. Capturing audio as PCM 44100 stereo. My PC has a SL9KE chip which is a P4 3.2ghz HT 2mb and 1gb PC3200 2-2-2-5 ram. XP SP2 running clean and defragged. 39 minutes of video resulted in a 12.6GB file! MLC was too slow to be usable even on the fastest setting. Lagarith is excellent! Capture Stats Frames Captured: 70261 Frames Dropped1: 0 Frames Dropped2: 1 Time : 00:39:04 Time Left: 07:08:19 Free Space: 148,803,293,184 Video Bytes: 13,163,442,847 Audio Bytes: 413,569,800 Total Bytes: 13,577,012,647 Video Bytes Sec: 5,613,729 Audio Bytes Sec: 176,372 Total Bytes Sec: 5,790,101 Video Compression: 2.767 Video Rate: 29.970013 Audio Rate: 44100.241432 AV Diff: -0.000005 AV Adjust: 0.000000 AV Actual: 0.000000

I don't see any way to set default modes in there, but in my ~\AppData\Local\VirtualStore I see
Code:
[settings] multithreading=1 lossy_option=3 |

Well, wherever settings go when WritePrivateProfileInt/String is used.
Quote:
lossy_option=3 means YV12. (0:RGBA, 1:RGB (Default), 2:YUY2, 3:YV12, 4:Reduced Resolution) suggest=1 means always suggest RGB for output. nullframes=1 means enable Null frames. From the sounds of it this isn't going to fix your problem though. Last edited by squid_80; 10th September 2008 at 19:13. |

my workaround is to use huffyuv with adobe apps (for RGB and for RGBA), after the project is finnished i would reconvert those huffs to lags for backups.
(ask for bat which controls vdub.exe and converts *.avi to *_lags.avi))

smok3, you can use the command-line utility avs2avi.exe (http://www.moitah.net/).
I've drafted a batch file (totally untested): Code:
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION if "%~1"=="" ( echo Usage: "%~f0" <source avi> echo Defaults to RGBA output echo For RGB24, name it as "blahblah_rgb.avi" goto :EOF ) set HOMEDIR=%~sdp0 set WORKDIR=%~sdp1 set PIXTYPE=%~n1 set PIXTYPE=%PIXTYPE:~-4% if /i "%PIXTYPE%"=="_RGB" ( set PIXTYPE=RGB24 ) else ( set PIXTYPE=RGB32 ) set SRCFILE=%~sf1 set AVSFILE=%~sdpn1_%PIXTYPE%.avs set DSTFILE=%~sdpn1_lags_%PIXTYPE%.avi set LAGSCFG=%HOMEDIR%lags_%PIXTYPE%.cfg echo AVISource^("%SRCFILE%",pixel_type="%PIXTYPE%"^)>"%AVSFILE%" if exist "%LAGSCFG%" ( "%HOMEDIR%avs2avi.exe" "%AVSFILE%" "%DSTFILE%" -w -p 0 -l "%LAGSCFG%" ) else ( "%HOMEDIR%avs2avi.exe" "%AVSFILE%" "%DSTFILE%" -w -p 0 -s "%LAGSCFG%" ) :EOF Last edited by henryho_hk; 11th September 2008 at 18:19.

henryho_hk: oh, sorry for confusion, i allready have a batch, what i meant is if somebody needs an example, i can provide. However, good batches are always welcome.
edit1: why do you need avisynth for this? edit2: ok, i just realized my batches wont do RGBA to RGBA but for some reason it ends with RGB lags, must take a look into this..

I use AVISynth because I use avs2avi. It seems difficult to fiddle with Virtualdub's (<1.6) VFW config in batch files. Mencoder supports VFW compression too but for unknown reasons it runs slower than avs2avi in my computer.

What if you run it from an Admin account?
