removing ads from a tv recording

[thecrock]

I have a number of dvd movies recorded from the television. I rip them from dvd to my hardrive using isobuster pro. I want to edit out the advertisements with as little fuss as possible. I know next to nothing about dvd recorders so i have a couple of questions.

1)Do dvd recorders flag the disk image at the point of the adverts(hopefully making them easier to remove)?
2) Is ripping as an iso image a good idea for editing?

I know that i could rip the dvd as an avi file and use virtualdubmod to edit it- but i am weary of all the audio sync issues i seem to get when editing this way. Is there an app that removes the ads automatically(i couldn't help but ask)

Any suggestions?

I'm not aware of anything that achieves this - as there's often no obvious, ubiquitous method of detection - especially given international markets.

I take it you are talking about a standalone DVD recorder?

In software, it tends to require a fair amount of tweaking.

2) Is ripping as an iso image a good idea for editing?

Well if you extract to a VOB you can directly edit with VideoReDo, which (the plus / beta version) has ad detection code in, which will very much help in this regard.

VideoReDo can directly edit the VOB, only has to recode a couple of frames at cut points, and is excellent at preserving audio-sync.

Well as I said - VideoReDo will allow you to directly work on an extracted VOB (or mpeg for that matter), and has ad detection software - I suspect that's as good as it gets, currently.

Thanks a lot for the reply, yes i'm using a standalone dvd recorder-i will definately be looking at VideoReDo, will rip the vobs with dvddecrypter or shrink. I will post back and tell you how it went.
Peace

Rip to mpg, and run comskip.
With a little tweaking, it can accurately identify where all the commercials are, and output a .txt file with the frame numbers.
You could then run comclean on it, which will read the .txt file, and automatically remove the commercials permanently.
Both files available in the forums at www.gbpvr.com

I just rip them to my HDD, open in TDA, edit out the ad's, ad chapters, make a menu, reauthor & burn to dvd, 3 easy programs,

DVD Decrypter (file mode)
TMPGEnc DVD Author
Nero

You could actually burn with TDA also.

And if you are using dvd-ram i just use IsoBuster or just copy and paste.

Noahtuck's suggestion is a good one but I would forget Nero and just use DVD Decrypter to do the burn.

Videoredo is also a very good way to go.. It is mpeg frame accurate and will not mess up audio sync, has a GUI that is taylored for cutting out commercials, it does have Ad Detective, which is the same as comskip, it is fast, does not re-encode and has great tech support. When your done cutting everything out it will save as an compliant mpeg2 file which you can drop into TDA. I have done hundreds of recordings this way with no problems.

[reboot]

But comskip and comclean are free

[TBoneit]

I'll go for the VideoReDo route. It is easy, it is reliable, And it works. I Never have sound sync problems.

Having said that the interface makes it very easy to move around in the file, the keystrokes and mouse click settings are customisable. The Ad detective works very well but as with any commercial detection scheme it needs to have its findings checked. On a couple of channels I recorded one or two of the commercials never went to black before the advert. I don't know if it is just something they do or if they do it to thwart cpmmercial detection as black detection was the way some VCRs detected commercials. But over all the COmmercial Detection worked slick and was a time saver.

And Yes VideoReDo is payware but has a free trial. Paying for something that works and works well is not a crime. Especially when the support is as good as theirs is.

Cheers

Edit: A couple of other things I do with VideoReDo as a FYI, I Open Vobs directly or mpg/mpeg, or Transport streams (.ts) and save as MPG (Mpeg/mpg program Streams), Elementary streams (mpv & mpa), or DVD stream (VOB).

[wwjd]

reboot,

You get what you pay for. With Videoredo you can see exactly where Ad Detective THINKS the commercial is and adjust as needed. I have done hundreds and I know from experience, no matter how much tweaking you do to comskip/Ad Detective, you will have to adjust the cut points at least 40 to 50% of the time. Auto detection and auto cutting of commercials is a dream not reality!

Using Videoredo I find that it is actually faster to find the commercials manually.

No, it's not. I have recordings here, done on my PVR-250, and I can prove it. You can run any check you want on the files, to see if they've been "doctored".
Yes, comskip does take an extreme amount of patience to tweak right, for YOUR computer/reception quality/logo detection/blackframe detection/CC's dictionary/etc., but it does work.
Combined with comclean (which is just a .bat that runs mpgtx (a free commandline mpeg editor), on the comskip.txt file, I have no more commercials in my recordings.
On some channels, it's better than others, but it's STILL far better than the 40 to 50%...closer to 5% adjusting/editing.
It's no dream.

[wwjd]

reboot,

Yes I have had a fair number of cases where the commercials were found and auto cutting them would have been ok. Yes you can tweak and get more consistant results for a given sitcom. But if you record shows from numerous different sitcoms over an extended period of time, then you will see numbers significantly greater than 5%.

In my mind even a 5% fail rate is too high and means that you really should check each and every cut. Why not pay a little money and use something like Videoredo and have the best of both worlds, auto detection and a fast easy GUI for spot checking and verifying the intended cuts.

Just use virtualdub to load them , locate the first frame of the video you want , lock it , locate the frame at the end , prior to the next add and lock it .

Make sure audio is set to full processing , change to 48k if need be .

Frameserve too bbmpeg .

Repeat the process for the next part .

Might take a while , but is damn acurate , and free

This can also be done using the batch mode in job list in virtualdub , a little faster ..

You could actually burn with TDA also.

If it's a non protected dvd, TDA will do all three steps. you can also use TDA to save as a mpeg to your hard drive.

[thecrock]

Bjs i can't use virtualdub because i'm not working with avi, i'm going to be working with vob as i don't want to recode the files.

A BIG thanks to EVERYBODY who posted here.

Yep!!!
Wait.. TDA will save as a mpeg ?? as far as i have ever known (and i use TDA 99.9% of the time to author my own videos to dvd) it saves to vob's ect. in a VIDEO_TS folder ?? unless i have missed something for the last 2 years

It's a fairly simple program but i love TDA!!!!!!
But if you rip with DVD Decrypter first it won't any longer be protected

Noahtuck's suggestion is a good one but I would forget Nero and just use DVD Decrypter to do the burn.

One problem with that... DVD Decrypter only burns ISO images, which TDA does not make

And i have burned 100's if not 1000's (being conservative) of dvdr's for people all over the world with maybe about .05% of people having any playback problems which i found out was due to standalone players playing any kind of dvd-r... so i don't go for nero being a problem at all.......

I'm not sure but are you suggesting how to or to use DVD Decrypter for this ?
Because i had the same problem as he has and not even DVD Decrypter would show anything on the disc at all, just saw it as a blank dvdr, not in any mode way shape or form and i tried the way on that link also.
The only program i could get to rip or transfer the files on the dvdr was with IsoBuster.

Edit: Oop's, got this thread partially mixed up with another one in my answer

[thecrock]

sorry guys, i stated earlier that i would try to do this using vob files. I will have to use iso because as said by noahtuck dvddecrytper wont rip the disk, i can only get isobuster to rip to my harddrive.

[Mister Flonk-Flonk]

Use MPEG-VCR to scene chop all the commercial segments out & resave as a new file.

[zak_swan]

I have a number of dvd movies recorded from the television.

forgive my ignorance but is it legal to record movies off of TV or anything off of TV?
What with all the copyright stuff i've been reading on here.
If u record movie off TV can u legally make a copy?

[hudsonf]

Wait.. TDA will save as a mpeg ??

Yes.
1. Add DVD Video
2. Point TDA to the VIDEO_TS folder of the DVD you want to copy
3.Select the title and sound you want to copy to your hard drive
4. select the option " Copy the clip video data to the HDD "
5. Choose a destination folder to save to and hit OK

you turkey



I knew that was there too (the little check box option) and i never even thought about it because i never use it and never have because i only use TDA to author dvd's I can't even remember the last time i paid attention to it, i just fly through so fast i don't even have to look at anything 8)

[thecrock]

So i could transnfer the dvd to my hard drive in mpeg2 format using tmpgenc and then use videoredo to cut the advertisements out and then burn the mpeg to dvd? Will tmpgenc give me 1 file on my hard drive or will i have to remux the audio and video before burning which isn't a problem?

[hudsonf]

TDA will give you 1 mpeg file.

Just a thought on automated commercial cutting.

Long ago, I did some experimenting with PVAStrumento. Tried the "broken GOP's" and some others but I seem to recall this option had something to do with Time Stamps. Which is where there would be a major break with commercial interruptions. Anyway, at one point the program gave me a video of nothing BUT commercials. Not what I wanted at the time. Cannot say for certain if ALL commercials were in this file, but there was NO movie at all. Process was totally automated.

The beauty of this method is that it does not rely on any visual recognition method, but works by checking the time stamps imbedded within the video. I have no idea if future broadcasting techniques might invalidate this method.

Reboot,

I can't find a link to comskip or comclean on the forums you linked to. Do you have a direct link?

Thanks,

If you use TMPGEnc DVD Author it'll give you one big mpeg, Note: You'll need to be running Windows 2000 or WinXP and have the drive be a NTFS or it'll stop at the 4gig mark. You could also use DVDDecrypter to create one big VOB file. VideoReDo will open either and allow you to edit and save as one file the edited results. I'd sign up for the free trial if I were you as a test of how you like it. Then I would go to their forums and get the latest beta of VideoReDo Plus with commercial detection built in and use that version. Then you take the edited MPG and re-author with DVD Author. Done. If you wanted to get fancy play the mpeg with a DVD Player Software and do some screen caps to use as menu background or edit out a sequence to use as a motion background. I did a Christmas Shows DVD where I used one of the dance numbers for the background. I was carefull to select a clip where there was space to put the chapter buttons using TMPGEnc DVD Authors menu edit function.

Just a thought.

Good Luck
