ok it works fine!!!!

Where is the ini file you use to remember the values? Or are you using the registry?

thanks!!!

I wont touch the registry. Waaaaayyyyyy to easy to screw things up.

I know that the registry is what you are now supposed to use for this kind of thing but I think ini files work just fine.

The ini file is "HCbatchGUI.ini" and is located in your "C:\Windows" directory.

do you mind at all putting it in the install directory? It is cleaner and lets users see all files installed....this is just my preference for seeing all files installed.

The .ini file is not deleted upon uninstall in any case.

happy new year!!!!

That's just the way my compiler does it. I didn't place it there by choice. Borland doesn't (as far as I know) give me a way to change where the ini is saved to. If I can find a way to change it I will though because I agree about having them all in the same directory.

is it possible to add msharpen? is there room in the gui?

sometimes I have some DV that needs sharpening.

you can get it at:

http://neuron2.net/msharpen/msharpen.html

It is a nice subtle sharpener. Nice default setting is:

MSharpen(threshold=15,strength=75)

Note that you can add a high quality variable...maybe a check box for high quality so you get:

MSharpen(threshold=15,strength=75,highq=true)

this would really finish your product up nicely!!!!

if you want to add this though, Msharpen MUST be the last part of the script....just like digital imaging, sharpening is last after all other effects, otherwise you sharpen noise.

I'll look into it. Wont promise anything right now though. Currently I'm working on making the app more stable for Linux (Ubuntu - which I'm really starting to enjoy. Right now I have the batch video working I'm just having difficulty getting the audio right).

If I can find the time to read up on Msharpen (so that I know what I'm doing... because I know nothing about that filter) I'll try to add it for you.

Hope you New Year went well ron!

Linux...HAHA...that is weird...I just put SUSE on a laptop to try...what a coincidence.

New Year was fun......our Malay neighbours had us (and 15 others) over for a ton of Malay and Chinese food.....still full!!!! All the kids came too.

I hope you had a good time as well.

The only reason I mentioned msharpen as I was thinking about what could be missing. Really all is here, denoising, audio transcode, encoding, etc. Really the only thing I could think of that was left out was sharpening (not that important, but it can make a nice difference). Really you could just add some presets with no high quality box.

for example, Default
Subtle
Subtle High Quality
Low Sharpening
Low Sharpening High Quality
Medium Sharpening
Medium Sharpening High Quality
High Sharpening
High Sharpening High Quality

or just use HQ for high quality.

Sharpening is the last step when you edit in photoshop or what have you and is often forgotten about with video. I will try to get up some preset settings, but I understand that you are busy.....but look on the bright side....I would not bother for enhancements anymore

Good luck with Linux port!!!!

Released v14.1

Additions include an option to shutdown the pc when done using pstools psshutdown.exe

Added Msharpen avisynth filter and user configurable presets.

New is version v14.1 optimized for linux wine.
It has the same functionality as the windows version but has been optimized to work in linux through wine. It is now fairly stable and can do anything the windows version can including creating your avisynth scripts, video encoding, and audio encoding (2channel ac3, upmix, 5.1, and wav extract)

You can get both versions at https://sourceforge.net/projects/hcbatchgui/

Hey...a new version....thanks!!!!

Seems ok....I did notice one slight problem with the Msharpen dialog.

If a user chooses "# Don't Load Plugin", then can still choose in the box below it MSharpen (and vice versa). In this case the script will be, for example:

LoadPlugin("C:\Program Files\HCbatchGUI\Convolution3DYV12.dll")
# Don't Load Plugin("C:\Program Files\HCbatchGUI\MSharpen.dll")
Avisource("C:\1..To Encode\TestDV.avi")
converttoyv12(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (preset="NoisyDV")
evn=SelectEven.Convolution3D (preset="NoisyDV")
Interleave(evn,odd)
Weave()
Msharpen(threshold=10,strength=100,mask=false,highq=true)

This will cause problems and the plugin is not loaded and yet it is called later (the vice versa case will not be so bad as you will load the plugin but not use it).

So I suggest that if use chooses NOT to load Msharpen that the box below is set to "# Don't Sharpen" and then greyed out so user cannot change. Vice versa case too if you want to be clean.

thanks again....never tested the shut down...maybe later...congrats on linux too!!!

also....the end you must accept the licence for the machine shutdown ON THE FIRST USE...so it will not shutdown in this first instance...maybe this should be noted on the shutoff page so user can goto install dir and run it first...all other times you use it is ok

few more things....

1. does the shutdown command need admin access? If so, maybe it should be listed where that option can be ticked.

2. Can you add VBR Bias and Last Frame I-Frame to template settings? These are pretty important, esp. VBR Bias. The default is zero which can make large macro-blocking....most use 30

3. You can get frame accurate chapters in your authoring package if the start of a chapter is an I-Frame....HC can do this if you supply a chapter file with the frames of the chapters...it then encodes that frame as I-Frame, this is VERY useful. Can you make the setup tab called "Setup/Chapters" and in it have a tick box (you need it so program does not use a file when not need to) and then browse to the .txt file to send to HC that has chapters in it? Does HC have as part of CLI an option for this? If not then maybe a page to enter the chapters and then have gui modify the HC ini file?

thanks!!! Other than this I really think this is all complete!!!

awesome on yur part 4 sure!!!!

I dug something up from my old avisynth stuff, especially for those who use the mainconcept codec. Also can help those in NTSC land, maybe you can put this on first tab, it is useful and does help in some circumstances. From Doom9 way back (still relevant):

http://www.doom9.org/index.html?/dv/guide.html

freebird73717 · Posted: Jan 15, 2008 14:44

Hey ron how's it going?

You've come up with some interesting suggestions.

ron spencer · Posted: Jan 15, 2008 17:49

I am OK...thanks!!! Linux seems cool...not too much time on it I must say though. In terms of chapter import, I will check into it as well, but it is USEFUL....

Now as far a reinterpolate411 is concered, there is no colorspace conversion issues as long as it comes right after avisource....all DV decoders output YUY2 anyway, so there is no color conversion if you use it right after avisource, and if you use the mainconcept DV decoder like I do then you get nicer output. So you do not need to convert anyway, unless you have an FFDSHOW YV12 going on, but 99.9% of people do not. So the example would be:

LoadPlugin("C:\Program Files\HCbatchGUI\Convolution3DYV12.dll")
LoadPlugin("C:\Program Files\HCbatchGUI\MSharpen.dll")
LoadPlugin("C:\Program Files\HCbatchGUI\ReInterpolate411.dll")
Avisource("C:\1..To Encode\TestDV.avi")
reinterpolate411()
converttoyv12(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (preset="GoodDV")
evn=SelectEven.Convolution3D (preset="GoodDV")
Interleave(evn,odd)
Weave()
Msharpen(threshold=10,strength=80,mask=false,highq=true)

This works perfectly and no colorspace issues.

Whadda think?

I hope you have been well......

On the chapter note....maybe a screen to have user enter chapters if there is no chapter CLI. User would need to enter number of chapters and frames of them, thenyour program would need to modify the HC ini...for example you would add this to hc.ini if you had 9 chapters with frame numbers as follows:

*CHAPTER 9
203
1056
1897
2409
2607
3371
4432
5430
6536

Will check later....kids are bellowing LOL!!!!

it is not the camera, but the DV decoder a person has on their system.

For example, I have some DV from my camcorder....I have mainconcept DV Decoder....it outputs yuy2 so on my machine reinterpolate will be good (necessary actually with this codec due to chroma error). But some decoders, such as Cedocida, let you choose whatever, even YV12. Others such as Panasonic are RGB only, so there is color space conversion needed. So if you know what you are doing, then reinterpolate() will be very advantageous (for NTSC only). So this is an advanced option, but it does have very nice upsides. Most decoders are yuy2, but there are some older ones that are not.

In general the 4 decoded color spaces are:

RGB24
RGB32
YUY2
YV12

with YUY2 being most used....

YUCK!!!!

well....I cannot find a way to pass a chapter file...Not sure you can add a window so user can enter farme of chaper like I mentioned up top. This then is copied to ini file for HC....

linux is not soooo bad BTW

Well according to the hc pdf there is a way to impliment chapters from the commandline.

ron spencer · Posted: Jan 16, 2008 16:32

lumigain has some issues with buffer overflows right now....I think hank is fixing it...

Bah....I forgot to read manual...duh!!!

I think it is easy then....the user needs to make the chapter file FIRST, typically as an export from their video editor.

In it are the frame numbers:

123
1441
12445

etc....there is no need for *chapters 3 in this case.

So user would need to specify location and file name....could you browse to it via a dialog like in the setup tab? so if that was c:\Video\Encodes\chapters.txt, then your command would just be:

-chapter c:\Video\Encodes\chapters.txt

Is it that easy? Remember, it is up to the USER to provide the proper chapter file in .txt format, not HCbatchGUI

I guess I better read HC docs more LOL!!!!
