Flickr is an online photo and video sharing website that allows you to backup photos and videos to share with other people in the world. You can upload videos to Flickr as the same way you upload photos. Flickr has created 3 content types to video i.e Normal Video, Screencasts and Animations/CGI. Flickr allows you to upload HD videos. To view HD video you need to upgrade your free account to Pro account. If you upgrade your accoount, the HD option will automatically appear. If you have a video in a different format which is not supported by Flickr, then you need to convert it into file format which is supported by Flickr.
Following are the video file extentions that are supported by Flickr: .mov (AVID or other proprietary codecs may not work), .mp4 (recommended with H.264), .avi, .wmv, .mpeg (1, 2 and 4), .3gp, .m2ts, .ogg, .ogv.
You can install PicBackMan's Flickr uploader for Mac from the website and start backing up photos and videos.
Quick Tip to ensure your videos never go missing
Videos are precious memories and all of us never want to ever lose them to hard disk crashes or missing drives. PicBackMan is the easiest and simplest way to keep your videos safely backed up in one or more online accounts. Simply download PicBackMan (it's free!), register your account, connect to your online store and tell PicBackMan where your videos are - PicBackMan does the rest, automatically. It bulk uploads all videos and keeps looking for new ones and uploads those too. You don't have to ever touch it.
