AutoGK hidden option request

[DRP535]

I'm only a very infrequent user of AutoGK so maybe this feature already exists or has already been requested, but I've thought to myself that a source range option would be very useful on occasion. By that I mean an option where you could specify the start and finish frames for the encoding.

I thought of this when I noticed that many movies these days add their studio logo in colour (like Paramount in particular) after the B&W end credits of the movie. If you use the hidden option to decrease the bitrate and greyscale the end credits, then when the studio logo comes up it becomes obvious what has been done. It would be ideal if the studio logo could just be discarded entirely and not included.

Of course I know that I can just do this manually after the fact with VirtualDub and a direct stream copy, but that's not really technically the best way of doing it.

Hello DRP535,

You could consider "torturing" the .d2v file :) ; the how-to is given step by step by ukb 007 here: http://forum.doom9.org/showthread.php?s=&threadid=83382

I'd have to agree with DRP535 on this. Could prove to be a very useful option once AVI-file input is implemented. I am currently testing encoding TV-captures using GK, but I am very pleased with the automation in AutoGK.

If AVI-file support means support also for AVS (Avisynth) file input, then this problem can be solved using the trim functions in Avisynth. If not, the I would really like to see this in AutoGK, otherwise I will have to stick with GK (which is really not a bad idea, but you have to do more work yourself).

Keep up the good work Len0x. I like the results from it very much!

Hi BigDid and thanks for suggestion. I read that post but to be honest that's a bit more work and complication than I really need and is justifiable for the minor annoyance I pointed out. If it would take that much effort to do, I just wouldn't bother at all and learn to live with the B&W Paramount logo after the credits.

Like I said, I am only an infrequent user of AutoGK and as such not fully into all the technical underbonnet workings of it. Its automation of all that technical stuff is what I value it for, so I'd be reluctant to start complicating it up again. Like the next poster said, if you want that kind of flexibility there's always GK instead. I just thought I'd mention it though since it would seem to me to be a nice fit with the other available hidden options. If len0x deems it a worthy enough idea to add then great, if not then I'll learn to live with it :-)

No it doesn't mean that... You will always need a proper video file to start with.

Firstly, thank you developers for such a wonderful project and program. AGK is very easy to use and free! Amazing.

I would love to see a greyscale encoding option in AGK. I mainly process classic b/w movies and this would be an invaluable add to me personally. I know it wouldn't save much on file size, but that wouldn't be the point. It can help avoid the purple and green rainbow effects in some rips. Short of adjusting someone's television set to remove color, a greyscale built in would be fabulous.

Now if I could only get the force mono box to work again (it apparently has stopped and AGK is processing in AC3, even when I tell it not to). Oh, got that figured out. Tried to create a file for 1/6 DVD when the force will only work with 700mb option. Doh!

Thanks again.

Hi and welcome to the forum,

I suppose using greyscale credits should work (hidden option with Ctrl/F9).
Set frame=0 (or 1),quality to 100 (percent) and check greyscale and encode credits with different settings.
That should trigger the credits with greyscale at the beginning of the movie.

Make a test with a regular encode and the greyscale tip to see if quality is comparable with Drfanalyser between the 2, use a short clip to save time; you can cut mpeg2 sources with mpg2cut2 (or others).

Now there are filters (in avisynth) to remove those "pesky rainbows" but not directly usable in AGK :search: on rainbow(s)

To add to what Did said, using the Credits hidden option should work for you. Most of the B&W movies don't have any scrolling credits which needs to be separately compressed to save on bits, so you are OK there.

Another option is to use AGKPal (http://forum.doom9.org/showthread.php?t=100517) and add Greyscale() in your avs script. Depending on the severity of the "rainbowing", perhaps you might need to use an actual Derainbower (use forum search to get info on Derainbowers).

[sigloxx]

Thanks for the replies. I'll look into them.

The greyscale for credits option doesn't really do anything, as it doesn't apply the greyscale option to the entire movie, which is what I'm after. I can look into using the plug-in and adding the line to AviSynth, which should work.

I was thinking perhaps by using the greyscale credits feature, then altering the contents (if they're editable) of the option created, it may also work.

Either way, I'll look into it further. Greyscale will also remove the rainbows.

I've also turned off any color correction, as there isn't really any color to alter (other than b/w) and that has seemed to help quite a bit.

Thanks again.

Are you sure?

Set frame=0 (or 1),quality to 100 (percent) and check greyscale and encode credits with different settings.

Did you -really, effectively- tried the above proposition with all params?

Did

[sigloxx]

Did, no, I haven't tried to switch the parameters, but I will. Without switching them (I assume with Notepad edit), it doesn't work at all on the entire movie, perhaps only the credits, which is what the AGK method was originally intended for. Haven't gotten around to it yet, but will report back the results once I do.

Ah, got it, I set the frame to 1 and set to 100 percent. I think before the default was a lot lower, like 24 percent and frame at 0. I'll see what happens.

Glad to know that , I also have been sucessfull with same params (frame=1) ;)

Seems like the frame = 1, greyscale, encode credits, doesn't work. I've tried it on a few movies and I get a bit of color in the beginning (DVD capture edit), prior to the movie actually starting. With a full greyscale encode, I shouldn't see that color in the resulting avi. I may have to try the AviSynth plug-in method.

Hi,

It is kind of difficult to "Try" Avisynth cause you have to learn it first and you can have to learn a loooooooooooooong time (I'm still learning ;) )

So you may have to reset the codec to default to get rid of the zone(s) mixing up.
Taskbar -> Programs->Xvid->Configure encoder(Xvid Configuration)->"Load Defaults"

Close the window (Xvid configuration) launch AGK and when encoding (ie, for the comptest) you can verify that a new zone starting frame1 is created; by 2-clicking on that zone you can verify that greyscale encoding is checked; you're done :D

[sigloxx]

Strange, wonder why the XviD reset would work. Since AGK relies on the defaults anyway, doesn't it? No amount of programming the XviD panels will alter how AGK behaves, though I suppose it's possible that default associations could be meddled with.

Since I've turned color corrections off, the rainbow effects are nearly nill, which is partially what I'm after.

I may mess with things later as well. Thanks for the suggestion.

Cause at 1 point, it got messed up.

Your choice, but dont bother to ask for help if you don't want to try the given solutions. I'm out.

[sigloxx]

Thanks, Did, the solution appears to have worked. My first attempt after looks like a greyscale encode. Thanks.
