Vegas Movie Studio as well as you to come up with stunning videos were giving minimum effort. This software leans towards the more experienced side, and is really only suitable for those with a true passion for video editing is not only does it have a high retail price but its interface and internal elements can be too complex and confusing for those just beginning.
The software that it came with is amazing, and works even better if you can use it correctly with Windows Movie Maker (save file as Windows Movie Maker, then import that file on Movie Maker, add effects, save, and import back to the Pinnacle software if you like). Or, if you don't want to use the Pinnacle software, that's fine too... just find on your computer where the file is saved at, and import that to whatever software you use. (As for Mac users, I suppose you could use garage band... I don't own a Mac so it would be difficult for me to say)
4) As some other reviewers have pointed out, the Dazzle chip is not a HD device. Even though Dazzle Video Creator Plus HD is it's name, it does not record HD video. This is because S-video and component (the two types of ports on the capture card) are not capable of recording in HD quality. What HD refers to is Pinnacle Studio's ability to edit and render HD video.
The T#i line is what they call a "pro-sumer" line, which is basically between a consumer line camera like a very basic DSLR and a professional DSLR camera, thus the term "pro-sumer." Typically what this meant is an DSLR with an APS-C sized sensor, decent resolution, and some hand-me-down professional features of pro-grade cameras from a few years ago. For this reason, sometimes it's not worth upgrading from one of these cameras to the next until at least a few generations have past (meaning if you have a T5i, it's not really a giant leap forward to upgrade to a T6i). However, the T7i is somewhat different. When I was doing research on what features it has and what it is missing compared to the pro-grade DSLRs that are considered "current" right now, I was surprised to find very little. The main differences really is that the pro-grade cameras have the LCD display on the top that would display all of your relevant camera settings, and then a few of them would also sport a full-frame sensor. Other than that, the differences are very minor. Something like maybe 1 or 2 frames less in burst mode or something like that. Nothing that would really jump out at you and make you regret not stepping up to the professional grade equivalent (Think it would be the 77D?). It actually has pretty much all of the big features of even their current pro-grade DSLRs, making the T7i probably one of the best prosumer DSLRs to buy.
