Not sure if this is the right place to put this, but it does involve the 24p pulldown...when recording last weekend I would have scenes that went on for 15-20 minutes at a time, and maybe contain 2 minutes of footage I actually want to put into a movie...

What is a simple way to clip m2t files, because doing pulldown will be ALOT more convienient if I just have to process a short clip...but I can't really find a tool to do this that doesn't involve reendocing the .m2t two or three times, which I really don't want to bother with.

Any ideas?

I am not familiar with any tool that does that. In fact, from developer's point of view, it would be pretty complex to create such a tool. :(

I would suggest you just record smaller clips if you need to remove pulldown.

Not really, I took a look at Apple's AVCVideoCap source code (available free on Apple site), and it would be trivial to implement clip length limitation and on proper boundaries at that. Don't know the situation on the PC side though.

Oh snap! :D I got it! Feel like a noob now tho, it works easy enough in MPEG Streamclip, just select in the in and out flag and save as a .ts transport stream file...then do the pulldown on it, works PERFECT.

Right, in theory my versoin of the "free" pulldown app, only the Vegas UI Plugin, could do that as well by utilizing the time markers in the Vegas settings.

VDub / AVISynth can take in the specific frames that you want processed, so even with the existing .exe, you could update it to do exactly this. There is a VDub setting that specifies the start & end frames. Just create a one off template and set the appropriate start & end points and it will work for you...

Hi,

I use MPEG2 VCR, it's a handy little app. You can bring your .m2t files into it and trim them quickly as you like, and save right back to .m2t format. I do this first before the 24p reverse pulldown process, saves on disk space too...
