AVANTI - FFmpeg/Avisynth GUI (support thread).

[Chris K]

I know you can by FFmpeg, but I'm no script writer.

The FFmpeg concat filter works but it can not be used on remuxing (copy) streams. You'll have to re-encode.

Avanti only allows two input streams so with some tricks you could merge two vobs and recode them to something else. You need to use the -new option on the user command line like this...

-new -i "@source1" -i "@source2" -dvs -filter_complex "concat=v=0:a=0:v=1:a=1" -das -y "@destin1"

Probably a bit cryptic for the average Avanti user.

Loading up AVANTI can be slow, I sometimes have to close the program down, restart it, several times. I haven't been following this thread closely, is there an update, or is it my machine ?

I do tests with Avanti on an old Athlon 1.66 Ghz single core and the startup time there is somewhere between 5-10 seconds.

Your profile tells you're on XP SP2 is this still the case? Your machine (CPU speed) should be OK.

Avanti runs a copy of FFmpeg and if you point to a location on a slow device (e.g. memory stick) to find FFmpeg, this could slowdown the startup procedure.

If you have FFmpeg just in the default Avanti FFmpeg folder and run from a normal HDD location then I have no idea what's wrong.

At present my OS is Windows8, with a Quad Core CPU and 8 gigs RAM. It is normal for this program to load slow, eek.

As I wrote... on a slow Athlon machine with XP in 5-10 seconds. But there are compatibility issues on Windows 7 and the same can be expected on Windows 8. You could rename the folder in which you installed Avanti a bit and see what that does. Paths are the big culprit for Avanti on Windows 7.

The new version will come (soon) stored in a predefined folder. I have stable results with that.

Is there any chromakey functionality in FFMpeg now or am I really just asking for too much at this point? I've been using the same build of FFMpeg for the last three years and recently upgraded it and Avanti so I really don't know what major changes have taken place, so if my questions seem retarded I apologize.

Not at an easy to use user level but it wouldn't surprise me if it can be done. Perhaps with this ...

But there is so much more currently in libavfilter and the -filter_complex option. In Avanti you can do almost anything that FFmpeg offers with additions on the user command line but it requires a lot of research to find out how.
