I guess that's my question: at what point do I need to "tell" it what I want, after dragging the TS file onto the Streamclip. I'm not seeing anything that asks me what I want, so in order to get something "moving" on the screen, I'm clicking on the arrow at the bottom of the page. I think this is achieving the goal, but not sure.
OK. Once you drag the Video_TS folder into MPEG Streamclip, the first thing I would do is to push the Play button, (or hit the spacebar) to play the video and see that all is well.
When you are ready to convert the video, use FILE/EXPORT TO QUICKTIME and choose Apple INtermediate Codec for the compression.
YUP, that's what I've done!!!!!
Am so encouraged that it actually looks like I will not only be able to finish up the DVD for this grant before Monday morning, but may also have time to sleep and eat! Thank you so much, everyone, for guiding me through this process. Am hopeful it will prove useful to someone else wandering in the wilderness of technology!
