Adobe Media Encoder has a preset for YouTube which encodes to the typical and should I say traditional 320 x 240 pixels. YouTube has since moved into the “HD” category (no, nothing like Vimeo just yet) and supports a bit higher quality uploads. Uploads are limited to 10 minutes, file size limit is not set. H.264 MP4 is a good codec format to use (x.264 will do), but others are just as well supported.

And now for the promised ideal dimensions (as of today) and according to my testing:

640 x 360 px

MD5 checksum is a number used to verify integrity of files. Let’s say you download a file from the internet and want to make sure it is the same file as the one you intended to download (i.e. there was no man-in-the-middle attack, or no integrity corruption happened during the data transfer).

I found the easiest way to check this number in Windows is to download Nero MD5 Verifier from http://www.nero.com/enu/tools-utilities.html then 1. copy paste the number from the issuer, 2. browse for the file to be checked. Done. If the number in “Step 1″ appears green and is identical to the number the last text box you’re on.
