The utility supports:
NBTVA (standard 32 line)
Baird (30 line with outermost 3 lines widened)
TeKaDe/Telehor (30 lines landscape)
Visionette (24 lines, 30 frames/sec, landscape)
The utility allows video to be created from bitmaps either provided internally or user provided.

NBTC7E1.tmp
Depending on your system the temp folder is usually something like
C:\Users\<your>\AppData\Local\Temp\
gary wrote:Albert, when you create the file can you play it? That's after it is created do you then get a dialog box saying:
"Video created
Press 'Viewer' button to preview
Press 'Save As..' to save to a file"
and then if you press the "viewer" button and press start does it play?
Viewmaster wrote:Yes Gary, it sure does. Everthing works OK on all formats, except the save.
Viewmaster wrote:Well thanks for that reply, Gary. I shall have to ponder upon all that and then re read it.
Thanks once again for all your suggestions re OmniNBTV.
I created a 2 minute file from it in its new folder, with only line sync (no missing frame), and it saved all OK.

I just realised I may or may not have answered your question - if not don't hesitate to ask again..
gary wrote:Re the file saving - it's a shame really I would have like to have discovered the root cause of that.
