PDC Video Download

Hello!

Recently bought access to the 100 hours of PDC content.

Going into a scenario where I'm going to be without internet access for a while (beyond a small amount of mobile data) so I thought it would be worth it to upgrade to the tiny download.

Question... do I have to download each PDC video one by one? Is there no bulk download option?

I don't mind downloading a large file and walking away while it does it's business but one by one for all of the videos seems rather time consuming.

Is there a bulk download option?

If there isn't, why not? Why not have a download option that allows you to download a zipped file containing all 100 hours of videos so that someone can download it all in one fell swoop (at a shorter download due to the zip compression)?

Hopefully there is a bulk download option.

Please tell me there is! Oy!

Because the file would be too big.

I take that to mean that there is no zip file download option (drat).

Are you sure it would be too big?

Newer compression software has some rather amazing compression capacity. Not uncommon to get a file down to a tenth of its original size. Sure it takes time to compress it in the first place but wouldn't it be easier to download a single file the size of a 10 hour video over downloading many smaller videos that together equal 100 hours?

Daniel,

Take 100 mp4 files and compress them into a single zip file.   And then take that zip file and compress it into another zip file.   I think what you will find is that the final file is only 2% smaller than the original files.  Compressed files (like mp4) tend to not compress very well.

Righty-o!

Challenge accepted =).

Now I'm going to download all the PDC Tiny Download files and try compressing them just to find out how much of a reduction there is or isn't!

You may very well be right but I'm going to experiment and find out personally =)

You might want to try and compress a handful of files and see what happens.  

You will find that if you compress text files and xml files and html files - those compress REALLY well!  Like 90% or more!  But files that are already compressed tend to not compress much - and sometimes will end up even bigger!

Sometimes you can find a compression that might get 5% compression - but then you send it out and get 90% support calls saying they cannot uncompress it.  This is why the podcast gobs are in uncompressed zip files.   The mp3 files generally don't compress well, but sometimes a really great zip tool will get 2% compression but other zip tools will not know how to decompress that "fancy" compression.

Good to know!

Personally I'm hoping some of the newer compression technology will still have a decent compression rate on video but... there's a strong chance your right.

So yeah =D I'll simply try it and find out!

Because man if it doesn't?

Boy does it take a long time to download these videos!

Eh... here's an alternative thought~

USB 3 and higher is coming out (approximately 5G transfer speeds) so the older USB 2.0 technology flash drives are now very cheep on the market [$3] (approximately .5G transfer speeds).

Ever thought of offering to mail a flash drive with the content on it as an alternative to download? If so what were your conclusions?

If you haven't thought about it previous, what do you think about it now that I bring it up?
