I have a TV show that has a channel logo scene that is displayed ever time before going back to the show. From what I've been able to gather is that using a cutscene file will allow cutting the video at these points. And it would seem that you can create said file by using the -u, --dump=<int> argument. However, when I use this argument the program seems to just dump every frame from the video one-by-one into the dump file. Is there some tutorial or more information somewhere that I just could not find or can someone enlighten me on what I am doing wrong?

running:
Linux Mint 18.0 | kernel 4.4.0-59
comskip 0.81.089

command used:
Code:
comskip -u 102300 --ini=comskip_default.ini video.ts

Drag and drop the recording on comskipGUI.exe
let it run till completed
Click on the time bar at the top to navigate to where you want the cutscene being recorded.
Hit F1 and see what key to press to save the current frame as a cutscene file

Okay, so first off, I'm using linux. So I tried running comskip-gui and I received an error "ComSkip: missing option <file>. So then I run "comskip-gui --ini=config.ini path/to/file.ts" and it runs displaying the video, however, once it completes the pass it closes and says "Commercials were found. Close window when done." Not sure where to go from here.

Seems the linux comskip-gui is incomplete and does not support the reviewing.

I'm trying to tune a specific .ini file for a TV channel that doesn't work with default settings neither with Comskip nor Videoredo Ad-Detective.
This cutscene feature works very well, as I captured two DMP files and enabled cutscene mode in my INI file:
Code:
detect_method=132 ;1=black frame, 2=logo, 4=scene change, 8=fuzzy logic, 16=closed captions, 32=aspect ration, 64=silence, 128=cutscenes, 255=all

cutscene_frame=0
cutscene_dumpfile=""
cutscene_threshold=10
cutscenefile1="paramount1.dmp"
cutscenefile2="paramount2.dmp"
cutscenefile3=""
cutscenefile4=""
cutscenefile5=""
cutscenefile6=""
cutscenefile7=""
cutscenefile8=""

After processing the MKV/TS file from TVHeadend and opening the resulting Vprj file, there are the "red marks" indicating the cutscenes in the correct positions, but the blocks are not marked as commercial (i.e. found none).

What I was trying to do is instructing Comskip to begin marking commercials with the first cutscene and then stop at the second cutscene; the two marks must be between 4-8 minutes of distance between each other. Also, the best would be align the block at the scene change before/after the two cutscenes.
Is something possible?

The cutscenes generate cutpoints. They do not force block start/end
In the GUI you should be able to confirm cutpoints have been added at the cutscenes
Are they present?
Forcing block start/end is behavior not yet present

I'm unable to tell from the debugwindow, even after reading the manual; what colour should they be?
Here's the result window after processing.

If I open the resulting Vprj file in VideoRedo I get:

So definitely Comskip detects the correct cutscenes, but does not create the "blocks" (in my image above: 1, 2, 3 and 4).

Yes, I could, but basically I just wanted to know which is the method to make Comskip work in cutscene mode "generally".
Set the detect_method=128 and cutscene_threshold=10 (for example), then pass the cutscene files and then...? How would it mark the commercials?
I'm already done that but it seems not to create the blocks, even if my min_commercialbreak < cutscene distance (see picture above) < max_commercialbreak. Am I missing something?

The cutscenes are only used to find where to cut. Not for deciding if something is show or commercial
You need the use the regular scorimg methods for that

I was able to solve the problem, eventually, by reading this post:
http://www.kaashoek.com/comskip/viewtopic.php?p=1900#p1900

So the important INI parameter that I was missing was:

global_threshold=0.95

... that toghether with:

detect_method=128
delete_show_after_last_commercial=1
delete_show_before_first_commercial=1

and the INI posted before now works well.
How can I improve it with scene change, as the cutscenes are a couple of seconds "inside" commercials?
I've tried with detect_method=132 (128 cutscene + 4 scene change) but the output frames are exactly the same; on the CSV however, I have this for example:
Code:
sep=,
frame,brightness,scene_change,logo,uniform,sound,minY,MaxY,ar_ratio,goodEdge,isblack,cutscene, MinX, MaxX, hasBright, Dimcount,PTS,2500

The cutscene is detected (correctly) on frame 72302, but the commercial should end at 72325 included (72326 is the show). Any suggestion on how to "align" the cut correctly?
