I was looking at several clips and when I loaded on there wasn't any audio playback. Loaded several more and still no audio playback. Restarted VideoReDo and everything was back to normal.

I was checking a clip I just edited. As I was moving the slider it would not move past a point about 3/4 the way into the clip. Play would move me past that point but I still could not move past the point where I stopped playing. Restarting VideoReDo solved the problem.

I have a new problem. I have been trying to cut out parts of a video and convert from letterbox to widescreen. The output file has only one channel of audio, PID81, which is the wrong one. I have tried multiple ways of doing this and can not find a way to get the main audio, PID80. I have done each step separately and it looks like the main channel of audio disappears when converting from letterbox to widescreen. Restarting didn't solve this problem and it is repeatable. The other problems went away with a restart.

I was just about ready to uninstall and start over.

Can you replicate?

Are you using the latest build? 629? If not upgrade. It supports multiple audio streams so all audio should be retained during output.

If you don't want all the streams then you need to select the stream you do what via the Tools->Select stream dialog, then when saving click Options and uncheck the "Allow multiple audio streams" option. Then only the one you selected will be output.

I am using the latest 629.

I select the main audio but it outputs the secondary audio.

The last two shows I have converted from letterbox to widescreen have ended in a crash after the processing but before the final dialog box.

Try selecting the main audio but unchecking that "Allow multiple audio streams" option I mentioned.

One thing we're unable to do right now when outputting WTV files is set a preferred stream. So while the original file will have a designated preferred stream, a WTV output by VideoReDo and then reopened will always just select the first stream in the file. This is something we have a fix for, but it's not part of a public build yet.

I guess that means that I can't convert from letterbox to widescreen and keep both audio channels.

When I convert from Letterbox to widescreen and have Allow multiple audio streams enabled I only get one audio stream, the wrong one.

When I follow your suggestion and disable multiple audio streams I only get one stream, the correct one.

This doesn't happen with all recordings, just some.

Why do you think that? This shouldn't be an issue.

What kind of file is this? If it's anything other then WTV can you please open it in MediaInfo and copy/paste the info here.

It was an off air recording from the local PBS station. The file was edited to remove the beginning and end.

@MrVideo:
- Quicker converting from SD to other format in MPEG4 [not all have quadcore 3ghz+]
- Maybe he has no HD subscription
- Maybe his STB doesn't support HD
- Maybe his onboard card doesnt support HD
- Maybe he just wants to have 'a' version rather than a big sized [higher quality] one.
... who knows.

I have plenty of HD channels, but sometimes I prefer capturing the SD feed.
[What's the use encoding 1935-1945 war stuff from HD, its shot on 8/16mm tops]

He wasn't converting, just editing.

- Maybe he has no HD subscription
It was PBS - OTA

- Maybe his STB doesn't support HD
It was PBS - OTA - HD automatic as part of ATSC tuner.

- Maybe his onboard card doesnt support HD
Impossible. All ATSC tuners support HD, if they display to the computer's monitor. Otherwise, support is not required as the stream is captured on the computer and VRD works with the select video stream.

- Maybe he just wants to have 'a' version rather than a big sized [higher quality] one.
Ugh. It is ATSC. You don't get large HD files with ATSC :D OK, they will be larger than SD files, but the quality is so much better. NOVA is SO MUCH better in HD.

What's the use encoding 1935-1945 war stuff from HD, its shot on 8/16mm tops
Because, if the film was retransferred to HD, the quality will still be much better than the SD transfer. A film scanned with 1080 lines will me much better than the same film scanned at 480 lines. It doesn't have to be 35mm film in order to get the HD treatment.

Maybe I missed the HD broadcast and my only choice was a SD rebroadcast on a sub channel.
IIRC, it aired twice in HD, once WED night and then again SUN night. That assumes your local PBS station follows the PBS network schedule on WED and SUN.

The original air date for the NOVA show was:
Friday 10/31/2003

The last air dates here were:
11/17/2011 6 a.m. on World
11/17/2011 noon on World
11/17/2011 5 p.m. on World

World is a SD subchanel here.
I did not record it in '03.
Back then it was properly broadcast in SD anyways.
I recorded the 11/17/2011 6 a.m. showing.

After double-checking, the string theory episode of NOVA's Elegant Universe aired in HD on 11/16/11. It was not aired again that Sunday.

It may not have been in HD back in 2003, but it was widescreen, so that upconverts to 16:9 fairly well. A widescreen upconvert to SD is better than a widescreen downconvert to SD letterbox, where vertical resolution is lost in that process.

What did you use to capture the program? A normal OTA card should have given you a Transport Stream, not a Program Stream.
