Utility: ShowAnalyzer Beta

[UniKyrn]

Ok, I earlier reported that the "do not mark the last N as commercial" wasn't working in 0.6.1 and there were several replies claiming it did. I believe I've figured out why I'm seeing the problem.

As I originally reported, I ONLY has the "mark last" option checked, I didn't want the last 30 seconds marked as a commercial so I could avoid the PVR350 bug. What I saw was that the last thirty seconds continued to be marked as a commercial if it was indeed a commercial. What I didn't realize was that the first 30 seconds was never a commercial.

I changed the settings to:

neverMarkBeginSeconds = 30
neverMarkEndSeconds = 60

and reran ShowAnalyzer on a number of shows tonight, then looked at them to see how they were marked and what was in the log files. I found several examples of the last 30 and first 60 being forced as show instead of commercial, when the times should have been just the opposite. I believe one of the counter examples to my claim was somebody who was marking the first and last 180 seconds, and since they are the same value, the reversal would not have been noticed.

It's working, I think it's just using the wrong value, which is why I thought it didn't work when I was only trying to mark the last and not the first.

Jere,

I tried to send you a complete file but was unable to do so. Sorry. The current version (0.6.2) seems to do the same thing. In schoolhouse, I can load the file and playback but when I try to start the analysis nothing happens.

I am really guessing here, but I think that with HD you are struggling upstream aganist a fast river until Sage comes out with a version that does not mess around with the bitstream, but simply writes it to the drive. But I could be wrong.

I will try the next version unless you have some suggestions.

It would help for you to use WinRar or 7zip (not video editing software) to split it into 50 or 100 meg chunks. Then if one fails you don't have start over again.

I realize it is a long process, but it is the most effective means for me to troubleshoot bugs that I can't reproduce.

Jere,

I was unaware of these file splitting programs. Certainly, I will try to upload something Monday when I can get these files to a T1 connection.

I could be way out of date here (been using SA but never really worry about it ), but have you ever considered using the padding to aid commercial detection? For example a score modifier like "InPadding" or something.

[MrApollinax]

I'm not sure if it's what you are looking for but 6.2 has a four new options:

Always mark the begining xx seconds as commercials
Always mark the last xx seconds as commercials
Never mark the begining xx seconds as commercials
Never mark the last xx seconds as commercials

So if you have the EOF bug to deal with toggle Always mark last "1" second of a file as a commerical to skip that last frame.

[stanger89]

Actually I was thinking more along the lines that if it falls in the shows padding it's much more likely to be a commercial than show. So SA could bias it's calculations such. I pad a lot of stuff with several minutes beginning and end, which are usually parts of the leading/following show. SA (smartly) marks them as show usually, but it would be cool if it could recognize that since they're in padding they're probably not part of the show

[MrApollinax]

i see what you're getting at now. You could probably still use these new features to do what you want though. Setup a new profile for that show and toggle those to match the padding of the show you set up. So if you alway pad a show 30 seconds you could set SA to always mark the first 30 seconds as commercials. I'm having much more success wiht 6.2 than i had with 5.10 so I'll try playing around with these settings.

[stanger89]

Except I don't want it to "Always" mark the padding

[MrApollinax]

Has anyone had any success running SA on the show Lost? I've tred schoolhouse but everytime I change a setting another part of the show that i want marked changes. I've tried running with some of the settings found on the dragonglobal forum but I'm still getting parts of the show marked as commercial. I thought I'd bounce this off here as well to see if anyone has had any luck. My system specs are in my sig.

[Jere_Jones]

Since Lost seems to be one of the major problem shows, I've added it to my list of favorites. Thursday, I'll take a look and see what I can find.

Jere

[Jere_Jones]

Using the padding is an interesting idea. I'll look into it.

This show continues to foil my Com Skipping too! They seem fade to black more frequently and for longer amounts of time than a standard show..

Good Luck figuring this one out Jere! This show, and the new Battlestar Galactica are about the only two shows on TV now that I actually look forward to each week!

Jere,

I split up the file (into 33 100MB pieces) and you should have a complete episode within an hour of this posting. This is a 1/2 hour upconverted show.

On another note, I went back last night a played around with version 5.10. That version processes all of the files just fine, but the accuracy is bad. Maybe you could give me just a few suggestions. I have run schoolhouse on a number of recordings and have the following:

-With very few exceptions the edge frames get marked correctly but almost without fail, SA incorrectly marks the beginning, ending or some middle commercial as part of the show.

-When I try to adjust the parameter that caused this, I need to adjust it so much as make SA mark large segements of the show as commercial or vice versa.

-With regard to the middle commercial, since the length is under the "min show segment length" why does it get marked as show.(ie. How does a 30 sec segment between two commercial segments get marked as part of the show).

Any advice you could give would be appreciated. Since the edge frames are found properly, I would think a very simple tweak that I am missing would at least make 5.10 work at 90% accuracy.

Update: I got about half of the files there when it kicked me off. I am having trouble getting back on but will get it there eventually.

I am usning dirmon and showanalyzer together, its been working great but I have a question, I have 3 tunners sometimes recording at the same time 3 shows (as expected) and dirmon and showanalyzer can work on one show in real time. Is there a way to set up dirmon to be able to run showanalyzer on 3 recordings at the same time? I have pretty good system so I do not think that running 3 instances would kill my system in terms of CPU performance, also since it would be working on "live recordings" it should not take much of the CPU power anyway... Please let me know.... Thanks.

This feature is badly needed, yet it seems to continue to be overlooked.

[MrApollinax]

Jere has stated that a future release of DirMon will allow for multiple processors. Once that gets supported you should be able to run as many instances of SA as you want to handle your PVR cards.

[Wheemer]

Cool... I must have overlooked that. Can't wait!

[geogecko]

Ah, ha! That is what my problem was. Once in a while, while watching delayed live TV, I would notice that no commercial breaks were being detected, while recording. Now I realize, that another show was recording at the same time, and DM and SA were working on that file, and not the one I was watching. Then, all of a sudden, after the show ended in real-time, all of a sudden the commercial breaks showed up (SA got finished with the other show, and then started the one I was watching).

That makes a lot more since... Can't wait for multiple instance SA...

Does the latest version of ShowAnalyzer, ver 0.6.2, create .edl files ? They are not being deleted after Sage deletes the show. Anything I missed ?
