Downconversion of HD footage
M2t files...when producing a SD disc with with footage shot in HD does it matter if you downconvert via the cam when uploading files to the PC or when rendering from the timeline?

As far as I know, doing it in cam is faster (no computer down convert step) and takes up less HD space, but I only have one project recorded to HD that uses m2t, and I haven't touched it yet.

Thanks Jason. I ended up rendering the original HD files to plain NTSC widescreen, seemed to work fine. Since the files are the same size, it now occurs to me that there is no reason to down-convert from the camera...it's pointless. I just edit the files and render into the desired format and therby retain the original quality.

If you capture in HD you have the option to zoom in some if needed without affecting the image quality after downconvert to SD. The SD picture quality will also be better in my opinion.

If I had an HD cam, THAT is what i would be doing. Especially because I have not had a single bride request HD from me. The downside is of course less low light performance (from what I've heard) so there is a trade off. |

That is a good point Darrin, more flexibility in post. That is exactly what I needed to hear to know which way to go.
As far as cropping Jason, SD vs HD has to do with resolution, and I think you are referring more to 16:9 vs 4:3. |

Nope. If you display a SD frame on top of a HD frame, the SD frame will be much smaller (note that you have to not resize / stretch). If you keep the SD frame at native SD frame sizes, then the SD frame size will be 720x480, while the HD frame size will be 1920x1080. Plenty of room to fit an SD frame at native resolution in there.

I see what you're saying...I guess I'm still figuring this out. They are indeed different sizes!
