Visual Hub - Audio sync issues converting .m2t files from SA 8300HD PVR.

[Eug]

Hi. I have a Scientific Atlanta 8300HD PVR and have been using MPEG Streamclip to capture some programs, particularly ones in HD. However, the output format is .m2t.

I can play these files in VLC, but I want to convert the .m2t files to something more manageable.

I can use MPEG Streamclip to convert the files, but conversion to good quality H.264 takes forever, and doesn't always create a file that QuickTime can understand. Furthermore, straight output to unmodified MPEG2 simply doesn't work for some reason.

So, I downloaded the Visual Hub demo and it reads the .m2t files just fine. However, if I try to convert the files I get severe audio lag. I tried the MPEG and H.264 output settings as well others such as I think DivX IIRC but all had the audio lag.

Anyone have the same problem, or know how to fix it?

Do you have the x264 QT component (works great and is much faster than QT's h.264 encoder) installed? Use that from Streamclip.

Thx, I'll give that a shot with Streamclip.

However, it'd still be nice to get Visual Hub working as well.

Try this in the Advanced panel's Extra ffmpeg Flags:

-async 0

So, I tried it, but the audio sync was way off for some reason. I didn't have this problem with H.264 using the encoder already there in MPEG Streamclip.

OK, something else I'll look into.

Why does have to be so hard? :P
