How to split HDV files without loss of quality ?

[bokan]

I got tons of questions today ! :)

Can you please advise me wich software to use to derush my HDV footage (m2t files). I want it to create clean split of mpeg stream without recompression.

Thanks all.

If you want 100% lossless then export as tga/sgi sequence, or as quicktimes (png, animation, etc) I spit mine out at MJPEGB 95% - it's lossless enough without being ridiculously huge or CPU heavy.

Not sure if you still care, but I was happy when I discovered (freeware) MPEG Streamclip (http://www.squared5.com/). It cuts .m2t MPEG2 Transport Stream files at keyframe precision, resulting in lossless subclips. It can do lots of other conversion too that might come in handy.

It doesn't look great but it does the job best for freeware tools I've seen so far. If you got a better one, I'm interested.

Only problem I've found so far:
Footage with keyframed date/time/exposure/aperture metadata will loose that metadata. But the footage itself is still identical to original. I've contacted the author and he sais it's not his tool's fault.

I am not confident, but the VideoCharge is able to work with m2t files and to split without recompress.
