clever FFmpeg-GUI, small FFmpeg UI, fully portable, no installation.

I'm trying to figure out how to add AVS script, but I can't seem to be able to do it. I know you already have settings for the contrast, brightness, and such, but I'd like to change the hue to a movie that has a lot of yellow in it and try to shift it a bit more to the blue spectrum. I made a txt file with the simple 'Tweak' function, but I don't see a way actually to load that script into Clever FFMpeg in any way. It just says 'Test' or 'Edit' I even found a Virtualdub exe, but it is super confusing.

I have NO bloody idea exactly what I should choose to change the hue, but I'm just trying a script guessing at this one:

Tweak(sat=0.75, startHue=250, endHue=330)

But, I see no clear way to 'Load' or actually preview the script in any way. Any suggestions please on what I should do if I want to add AVS script, and specifically how I should set the parameters to shift the colour of the movie a bit more to Blue?

Here is a shot from the original m2ts file. I did set the contrast to +.08 and bumped up the saturation a little and that really did look better, but I would LIKE also to shift the color away from that yellow to perhaps more towards Blue:

If your FFmpeg is built with Avisynth support it shoule be able to just open the script as input.

Start clever FFmpeg-GUI, load your video, click encode videostream, click various, click use Avisynth, click create script, click edit script.

Enter all your avisynth filters and choices you like, then save the file.
You can preview the result with test script.
If it's fine for you, click encode.

Newest beta (v3.4.2.02), online now.
(Changelog will follow in the next full release).
With this version changes the update function.

Thanks! I thought I did that like you said, but when I chose Create Script, or maybe after I chose Edit Script, nothing showed, or it looked for a txt file somewhere that already existed. I tried creating the script I mentioned above, but it didn't look like it either provided me with an interface to create a script or allow me to navigate to the file I created. It just sits there and I THINK at that point it just locks up if I choose Test Script. I'll try again though, thank you!

I'm thinking that perhaps when one chooses Create Script, IF an interface then popped up with a blank field so you could simply write your script and when completed, simply allow you to Save script, and then Test script. But, the way it is now, at least to me, the navigation is confusing.

To edit the script you need a text editor like notepad or notepad++.
To test the script you need virtualdub2.
Both programs must be registered in the settings of clever FFmpeg-GUI.

Thanks mate, I'll give it a go! I did have notepad open and I did navigate to VirtualDub64, but I'll try again.

Thanks Bro!

One thing though... I tried to update the FFMpeg through the program and I got an error message that 2 dlls are missing and when I hit 'Okay' the program terminates. Now when I start the program it keeps opening to that error prompt and all I can do now is hit 'Okay' and terminate the program. So, it is kind of stuck in a loop now where I cannot use the program.

I think what I will do is simply download the entire new update and start over with that, I'm thinking that should work...

But, I thought you should know about that closed loop error where after it shows you cannot use the program anymore.

[john33]

Same here. Fresh download fixes it.

[ProWo]

This is intended, because without the dll's the program can't work.
As the message says, download the release (v3.4.5), extract all files and restart.
The last nightlys contain the exe only.

I don't know what I'm doing wrong (what else is new...?) But, I'm trying to add AVS before encoding. I'm doing my usual HDR-SDR to 1080 encode from UHD-HD. But, when I click on Avisynth and 'Add Script', I create the script which your program has kindly provided the basic template. I simply put 'add borders (60,0,60,0) because apparently the UHD file is a 1.67 AR and MediaInfo shows the resolution to be 3600x2160, I simply want it to be fully Blu-ray compliant with a full 1920x1080 AR as it should be (Don't know why the UHD file doesn't already have the Black Bars on the sides making it compliant?) But... when I add the script the program completely freezes up and I have to close it.

Am I don't something wrong in the few, simple steps to add AVS script (in this case to add borders to the sides to make it Blu-ray compliant?)

Thanks!

Hi Lathe,
for adding borders only, using avisynth isn't the right way; use padding instead.
Look at the pic.



First of all check the checkbox, then insert the frame height you want:
1080 in your case. The frame width is calculated automatically.
Then insert 1920 at pad width, 1080 as pad heigth is inserted automatically.
That's all. You can check with preview.

btw
the correct syntax is addborders(60,0,60,0)

Hey thanks Pro Wo Bro! Heh, good catch on the syntax. Excellent feature, glad you have it in there!
