Unable to use video clips shot with my devices in other, 2 , Adobe Pre and others

Question

I tried shooting a video, first since new iOS, I photograph a lot of hockey , I will combine video from different sources to a single file. I've this for years. I convert from .Mov to 264. I use a few diff programs, one is Streamclip, and Adobe Prem Elem.  When I try to open in either of these, the thumbnail look black and will not convert, this happened with both of my devices 4s and iPad.

OP, update, I was able to get it to work, but only after several days of trial and error.
First, Compressor does NOT come with a preset to create multi-track friendly MPEG-2's. This is serious issue because Compressor is part of the FCP/DVDSP/FCP Studio package and since DVDSP (4.2.2, claims to) support multi-track DVDs there should be a preset in Compressor.
Step one, copy one of Compressor's MPEG-2 presets for DVD and edit it as follows:
Video Format: NTSC (or PAL)
Frame Rate 29.97fps (not sure if others will work but my footage is in 30p)
Quality:
Mode: One Pass CBR
Average Bit Rate: 6.2Mbps (keep below 7.0Mbps, basically)
GOP (Group Of Pictures):
GOP Structure: IBBP
Closed
GOP Size: 15
Extras:
[X] Include Chapter Markers Only
Save and re-render using the preset with the above modifications.
In addition, once you are done re-rendering your videos, you must re-import the videos into DVDSP (remove and import) and re-add (remove and drag and drop) the videos to each track if DVDSP complained about a prior video.
Make sure that you add (drag it) to the very beginning of the track of else DVDSP will give errors about GOP alignment. Basically all the videos have to be exactly the same length.
Hope this helps!
