Sony m2t file workaround
This has to be the biggest oldschool trick I’ve ever stumbled across related to video.
If you’ve captured HD video with Sony Vegas, you’ll no doubt notice the filename extension is .m2t and After Effects won’t load these files.
I did some digging and found that it’s based on the CineForm codec which is licensed to Vegas, so you have it on your system. So After Effects should be able to read it. If you try with the .m2t files, it won’t. Huh?
Okay, believe it or not, the solution is as simple as this – rename the .m2t to .mpg
Ya, that’s it. Now try to load it and After Effects has no trouble recognizing it. I’m going to delve into Vegas to see if it can change the extension on files it captures to save a few keystrokes but at least I’m back to editing rather than agonizing over having to render my files to another format before taking them to AE.

That’s just completely wrong. m2t files have nothing to do with vegas or cineform. m2t are mpeg transport stream files, that’s the way sony hdv cameras record the mpeg video on tape, and vegas is merely capturing that to disk.

I wish there was a way to effectively transfer files from Vegas to After FX whether it being m2t files or .AVI’s because as much as I love Vegas I’m considering changing due to these issues. If anyone knows the best settings, even for DV files, I would greatly appreciate it. Sure, DV files work but the colours and contrasts change considerably. And outputting to frames, especially in HDV is such a headache with long projects. As for converting to MPG, I’ll have to see if it does what it’s suppose to.

well, actually, if you capture with cineform software, it goes from inter to intraframe compression so AE won’t crash because it’s now all “I” frames. that’s why it costs a lot.
