Exporting without re-encoding?

[Tony Connoly]

Are you sure about that Ann? The manual says “AVCHD Lite” and the extension is .mts. Maybe the Panasonic GF1 and other Panasonics aren’t true AVCHD, but they are heavily compressed/encoded nonetheless. In any event, I wish Premiere let you trim and join files without having to re-encode them. It seems there is demand for such a feature.

OK, AVCHD Lite is a subset of AVCHD and limited to 720p.
If you feel that strongly about smartrendering make a feature request.

They’ll probably include in CS6 to give me a reason to upgrade 🙂

Ann–does Smartrendering work when you’ve made changes to the underlying footage (such as color balancing etc.) or only when you’re passing the footage through without any changes?

Btw, would you happen to know whether Encore has the same rendering engine as PP?

Final Cut Pro Classic can do just what you describe – it can trim and export some codecs without recompressing them, like DV and DVCPRO HD. I think we should all ask Adobe to add this.

I’d be surprised, though, if you can find any software that truly trims AVCHD without recompressing it, unless it’s AVC-Intra. AVCHD is a different animal. In AVCHD, most frames borrow pixel data from the immediately preceding frames, making them very hard to slice up without re-encoding. I suppose it’s possible to just re-encode the 15 or so dependent frames surrounding a cut, but most software doesn’t go that deep.

Does CS6 have the ability to trim and export any codecs without recompressing them?
