Audio sync issues with WinTV files

Hi all
I use a Hauppauge HVR2215 TV tuner with WinTV 7.2 to watch and record free to air television broadcasts. I’m looking to create a DVD from a recorded local show which features family members to send to relatives in other States.

Win TV can record to either a .ts or .mpg file and either format plays back fine in WinTV, Media Center, Media Player VLC etc. Both file formats can be imported to the Vegas Movie Studio Platinum 12 and DVD Architect timelines but have a 1-2 second audio sync issue. VMS is updated to bulid 12.0.1184 (most current as at today). I also have an older version of Edius 3.6 which will import the .mpg file with no sync issue (the .ts file isn’t recognised). Re-encoding the original WinTV .mpg file (with no edits) directly from the Edius timeline using Procoder for Edius produces a correctly synced .m2p file. However opening and re-encoding the original .mpg directly in Procoder for Edius produces a .m2p file with audio out of sync.

I’ve tried selecting different codec options within WinTV with no effect. Fortunately Edius means I can achieve what I want to do, but I prefer using VMS these days and am left curious as to why it is so. Given that re-encoding directly within Procoder suggests it’s not just a VMS issue, but thoughts or suggestions would be appreciated.

Thanks in Advance
Robbie
Ps. I’ll also be sounding out the Hauppauge community.

Search "Hauppauge" or "PVR" or "Transport Stream" on these forums.
Not too keen on answering the same question a third time this week.
WinTv format is actually worse than TS with resync errors.

I'm with musicvid. Non-standard video formats and codecs, as those created by the Hauppage unit, are really something of a crap shoot in Movie Studio. Sometimes they work, most times they don't. At least not with any reliability. The video they produce simply isn't designed to be edited (any more than broadcast TV is meant to be pirated and burned to DVD).

Let me clarify a number of things:
1. Despite a thinly veiled and uninformed inference that my intentions are tantamount to piracy, what I am intending to do is not inconsistent with Australian copyright law and indeed is permitted under the fair use provisions of that law. (FWIW I hold copyright on a number of musical and visual art works and take copyright seriously)
2. Before posting I spent more than an hour and a half reading posts and responses on these forums without finding anyone who described the same problem I encountered or any suggested actions or third party software recommendations that have resolved it.
3. Notwithstanding the above I searched the forums using suggested parameters but didn’t find any posts that I had not already read or specific information that was relevant beyond generalisations that transport streams have problems or Hauppage files have issues.
4. I am still hoping to find a technical understanding why Movie Studio (which remains my editor of choice) has issues with files that are able to be played accurately in every media player I’ve tested them in and in Edius (owned by a broadcast focused company) and a couple of other editing packages that I’ve tried since my original post.
Thanks, Robbie

1. What are you feeling guilty about? Maybe read the forum rules first?
2-3. You need VideoRedo h264 or TSDoctor to clean up stream errors. Not understanding or not searching the suggested terms is a different matter.
4. Your files are TRANSPORT STREAMS, not program streams. Transport streams contain errored frames and some really nasty timecode / indexing discontinuities
5. Last time, I know they play fine on a software player. This has absolutely nothing to do with unpacking the media to raw unerrored bits for editing. Again, not understanding is not a cause for defensiveness.

Done, and best of luck.

I don't see anything wrong with this. If you're going to sell DVDs for profit, that's another thing.

(any more than broadcast TV is meant to be pirated and burned to DVD).

With TiVoToGo, I can download TiVo recorded shows to my PC. I used to burn them to DVD for private viewing but now encode them for mobile players.

Just like with a DVR, watching TV on my own schedule. Time Shifting.

Done is fine, but a question was asked and suggestions made so it would be discourteous on my part not to respond.

I’m feeling guilty about nothing and have nothing to feel guilty about, but I will always respond when someone incorrectly and inappropriately infers that I’m doing something I should feel guilty about.

Apologies that I was apparently not clear enough when I said that I hadn’t found any suggested third party software recommendations that resolved the issue. VideoRedo h264 and TSDoctor were amongst a number of programs I downloaded, installed and persisted with simply because they were recommended here on this forum but at the end of the day did not produce any favourable result.

The essence of my original post was why Edius (and a number of other editing programs I have tried since then) can handle the Win TV Files but Movie Studio cannot. Fortunately, I’ve had participants on other forums that have been able to articulate those reasons at a technical level pretty well so all’s good.

… and my experiences over many years have convinced me that the more I understand, the less I need to rely on luck.

cheers, Robbie

Yes, part of the Quickstream fix processing in VRD involves outputting as TS or PS MPG wrapper for use in Vegas Movie Studio. I feel remiss for not having made that clear.

You say that Edius is opening the files but not giving you good sync. That is because the audio track (resynced to the sanitized video) is not the same length as the original. These issues are very common, and I doubt anyone here will be able to help with support for your Edius product or Wintv format.

The success rate with VRD and Hauppauge files in Sony Vegas is high -- approaching 100%; I think most folks don't capture to WinTV format, since it has its own set of troublesome quirks, especially in editing environments as you have already seen.
