subtitles and ad detective not working

[roguewarrior]

Hello!

I am a n00b so please go easy. The tool does a GREAT job of not reencoding and removing unwanted content - many thanks for that!

My issues so far are:

1) I lose subtitles from my wtv HD content. I record a movie using mce windows 7, remove the commercials from my wtv source file and save it back to wtv and I lose my subtitles.

2) The ad detective does a real poo job of detecting ads. Is this because ads are now all hd and so, there is no change of screen format, that the detective depended upon?

3) Finally, I was having a problem saving my movies at first, as the tool seemed to choose the Spanish audio stream! I chose the English one in streams (there were two), but no joy, it kept saving it in Spanish. Finally, I chose the save as - in only one stream (under advanced options on the save as box), and it works great now.

Thanks,
David

I'll let Dan203 address 1 & 3.

2. You can optimize your Ad-Detective settings to improve commercial detection.
Here is a guide to assist you:

1) We only support closed captioning and DVB subtitles in WTV files. If your file has Teletext subtitles those will be lost. The reason for this is that Microsoft encodes teletext subtitles in a non-standard format and we can not figure out how to decode them.

2) Ad detective works by detecting black frames. If your file does not have an obvious black frame when transitioning from show to commercial it will not detect the break. I've seen some shows where they will do a direct cross fade from the show to the commercial, or vice versa, and that is something we can not detect.

3) WTV files have a special method for marking a default stream. Our output routine does not current support that method. MCE should automatically detect the stream based on the language of your system, but there are a couple of things that can mess that up. First if the original stream did not have a language assigned then it will be flagged as being English and if there are multiple English streams MCE will simply pick the lowest numbered on. There is also a minor problem with our code that can cause some languages to be marked as English even when they have a proper language code. This is rare, and has been fixed for the next beta. I'm investigating a way to add the default stream marker, but it's difficult so I'm not sure how/if I'm going to be able to do it.

Thanks - how do I figure out if the CC is teletext versus CC?

Indeed - they are almost leaving zero black frames between the transitions. It is nasty, but hey such is life thanks! I can do it by hand.

No worries - this was more an FYI than a bug, I work around it just fine. Thanks again!

Open the file in VideoReDo and click Ctrl+L. If you see the subtitles listed, but they are not being preserved in the output file then something is wrong. However if there are no subtitles listed at all then they are likely teletext.
