Editing HDTV captures on Mac OS X?

For my PAL SDTV captures, I've been able to easily remove the adverts/commercials and trim the start and end points with Avidemux but the program doesn't cope with performing the same tasks on HDTV .ts files. The final result nearly always suffers from audio sync issues.

I could run VideoRedo from my Bootcamp partition but I'd really prefer a Mac option instead and one that doesn't involve re-encoding. Can anyone offer recommendations? Although Avidemux is free, I'm happy to shell out the cash and buy a program that will get the job done.

Thanks as always. 

Try ClipWrap or EditReady.

I tried both of them and they don't read .ts files, unfortunately. Thanks though.

Have you tried mpegstreamclip?

BTW, are files within the .TS container MPEG2 or H.264?

For SDTV broadcasts, the files within the .TS container are MPEG2 and for that Mpeg Streamclip was usually my default choice :) but it doesn't even recognise the H.264/MPEG4 AVC based .TS files that my PVR churns out from HDTV recordings.

Have you tried ffmpeg to convert to a .mov?

e.g. ffmpeg -i <input-ts-filename>.ts -vcodec copy -acodec pcm_s16le -ar 48000 -ac 2 <output-filename>.mov

I'll give it go and tell you what happens. :)

Success! After processing and converting the .TS via FFMPEG, I was then able to import the .MOV into Mpeg Streamclip, then perform the necessary trimming to the start and finish and the final .MOV plays in VLC without any audio sync issues whatsoever! For the future, I know what to do and hopefully this will be of benefit to other Mac users too.

Thanks so much for your help with this. 

Took me a few false starts, but glad it got you over the line.
