Those are two very different formats, so they're going to have very different needs.
If those .mts files are from an AVCHD camcorder, find out if the camcorder shoots in 1920x1080 or 1440x1080 and whether it shoots in stereo or 5.1 audio, then make sure that the project you start uses the correct project settings for that format.
MOVs can be any of hundreds of codecs and formats. What kind of camera or camcorder did these videos come from?
Once you've got the proper project settings for each video source, you can share it in many MOV compressions and quality settings so that it fits within your size parameters.
One is AVCHD (mts) from a Canon camera that I use more for action. The other is a Kodak Zi8 flip type camera that records in .mov. That one is just used for close-up interviews with coaches/players.
In elements 7 & 8 I played around and got the file small enough and saved both as .mov files. They need be to be around 4-5 mb for a minute video in the .mov format at 640X360. They are saved in h264 codec
But the Elements 9 I am trouble getting either one small enough yet with clarity like I did in 7 & 8.
I did about 40 tests in different settings and never got it. The final product when playing back in quicktime is blury. I'd take any help or advice you can give on settings and what do. I'd probably buy Elements 9 if I can figure it out.
You still haven't told me enough about your camcorder to be able to help you, bashhawk. Canon, after all, makes many many models of cameras and camcorders.
If you're talking about a Canon Vixia, however, the camcorder shoots in 1920x1080 stereo -- but only in FXP mode. You may not be able to edit video shoot in other, lower quality modes in Premiere Elements.
Same with that Kodak. I'm not sure you'll be able to edit that video in Premiere Elements. Not without a lot of experimenting to find just the right settings.
But I'm sorry, there's no universal recommendations I can offer.You may be in a gray area where the formats you're editing may or may not follow the regular rules.
Yes it is the Canon HF20 Vixia. I am shooting in wide screen.
I can do it in both Elements 7 & 8 with both cameras so I assumed I could do the same in 9.
