Can you swap .m2t and CFDI in a timeline?

With Vegas 7, playback of CFDIs is now slower than it was in Vegas 6, and considerably slower than playback of .m2ts. But we still need to use CFDIs for rendering if we are doing compositing, complex color corrections, etc. Because of the generation loss issue. I've read that Sony and Cineform are working together on a solution to improve CFDI performance in V7.

While we wait for this, I would like to ask if anyone has tried doing a project with .m2ts on the timeline, then swapping them with CFDIs at render time using "replace media". Can it be done, or is there a timecode problem? I guess this would be sort of analagous to what GearShift does with proxies...

Anyone know and/or tried this?

Thanks!

Can't be done. They won't line up. Even a recaptured m2t wont line up most of the time. That is one of the MAJOR drawbacks of HDV

"Can't be done?" I swap CFDI and m2t all the time. Back and forth. Not sure if I'm grasping what you're asking.

Caveat: m2t up until V7 didn't have accurate timecode, correct? So capturing twice, once direct to CFDI and the second time to m2t more than likely won't line up.

I capture the m2t. Then I create the intermediate from within Vegas. 2 identical length clips, different formats.

Of course, I normally (Vegas v6) go from cineform intermediate during editing to swapping to m2t for final render, as long as I'm not doing any keying. I don't see why you can't do it the other way around.

I'm using HD Connect. It saves the .m2t files and converts them (simultaneously). So I'm assuming they are the same (just different formats).

You might try taking a long clip, placing both the m2t and the CFDI on the timeline on separate tracks. Then go to the end of the clips, and toggle the video mute on/off and carefully watch the output in preview or external.

You should see no difference as you toggle.
