>>- Download the video
You can use the sample from our How To tutorial to download the media file: "Download a file from the Internet"
>>- Check that video plays as source video without any noise or any
Sounds like it should be an intelligence comparison that should be done by a human. I don't think that any third-party video comparison tool will give 100% results.
>>- Check for all other parmeters like quality, pixel, etc.. is same as source video.
It looks like this is what the sample above does.

It would be nice to have metrics that could measure "smoothness" and the like, but you're right. That won't likely be automatable until true AI is on tap.
That being said, is there any way to log or capture video for the person who is reviewing the test log to evaluate?

Hi,
Not been actively involved in this type of testing, so just a quick idea that came:
It might be acceptable for the quick smoke verification to get several frames at the known moments of time (say, every minute from the video start) and compare then the captured frames with the expected ones.
Obviously, the result depends on at least the used video codec.
Several links found by quick googling that might appear to be relevant:
