3 questions - First: What is the format that is used by Youtube to run its videos?

Secondly, can I somehow take a video I have uploaded to Youtube and make some still photo shots from the Youtube?

If so, how?

1. I don't know how to upload videos to YouTube,

however, once it is loaded to YouTube you can pause the video at the desired point, take a printscreen and crop the picture to remove extraneous data using a program like Microsoft Paint.

11. I have never mastered the printscreen function.

For a long time, I had a fabulous $ 35 program that did it for me, and it included a remarkable program that I used instead of Paint. But that company was pushed into oblivion when Micro$erf made Windows XP, and the Windows 95 software people in small companies couldn't move over quick enough. I still miss the ability to use the paint part of that program.

I found out last night that hitting PrntScrn on my computer won't do a screenshot. Rather I have to hit "ALT" while hitting PrntScrn. So that explains why I couldn't ever do that right.

I am still loopking for a program that will actually save still shots. I downloaded one that was supposed to last night, but it overwrites the first photo with the second photo, so it is not a lot of help, since I would like to do more than one single vid to still shot conversion. (My computer was very stripped down, and did not come with Paint. Somewhere or other I have some Photoshop DVD's so I could use Photoshop if I ever locate them.)

2. Do you have a copy of the original video you uploaded?

A video player like the (free) VLC can take a snapshot of one of the video frames.

If you don't have the video you can install one of the free youtube downloader addons to firefox
and download the video to your computer.

3. Okay that sounds good.

The VLC thing-ee you mention.

And how do I go about getting the free youtube downloader? Usually the spouse doe sit for me, but if he is not around, it would be great to do it on my own.

Very much appreciated.

6. If you aren't sure which frames you want,

you can get a free program like Irfanview that will take every frame from the video and stick them in a directory so you can browse through and see which ones you want.

Run the video in the program, go to "options" in the menu, and "extract all frames".

7. Youtube adapts videos to your computer, browser, and connection speed.

Their preferred download format is WebM or H.264

http://en.wikipedia.org/wiki/WebM

Some highly commercial videos still seem to require Adobe Flash, probably for tracking and copy "protection" reasons, but I see fewer and fewer of these. I won't install Adobe Flash on my computers.

Youtube's reccomended upload formats are here:

https://support.google.com/youtube/answer/1722171

Container: .mp4

No Edit Lists (or you may lose AV sync)
moov atom at the front of the file (Fast Start)

Audio Codec: AAC-LC

Channels: Stereo or Stereo + 5.1
Sample rate 96khz or 48 khz

Video Codec: H.264

Progressive scan (no interlacing)
High Profile
2 consecutive B frames
Closed GOP. GOP of half the frame rate.
CABAC
Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
Color Space: 4.2.0
