Here are the preferred YouTube video specifications for optimal playback quality: The maximum video file size on YouTube is up to 128GB (or 12 hours in length)-otherwise, there are no upload limits. While YouTube re-encodes every uploaded video to ensure high playback quality, it also encourages all users to upload videos as close to their “original, high-quality source format” as possible. Below is a breakdown of social media video specs for YouTube, Vimeo, Dailymotion, Facebook, and Instagram. Whichever platform makes the most sense for you ultimately depends on your content and goals. While Vimeo has a smaller audience, it’s also known as a “ home base ” for filmmakers and emphasizes video presentation, audio quality, and customization options.
Google-owned YouTube has better searchability and a higher viewership, but it’s mostly casual viewers looking for viral clips. While Film Shortage (which exclusively posts its content to Vimeo) insists there is no right or wrong answer, each platform has unique differences. It’s better to launch your film on one platform and then release it to others once you’ve gained some momentum. While taking the “shotgun approach”-uploading to every video hosting site available-may seem clever at first, the folks at Film Shortage note that initially posting to multiple platforms can dilute your impact by spreading out the number of plays and likes. The method is illustrated by synthetic data containing flat and dipping reflectors in depth dependent velocity media.It’s important to strategize when posting your new short film. We approximate the true amplitude weights for v(z) media by the weights for constant-velocity media, but accurately compute the takeoff and emergence angle terms that would otherwise contribute to a large error. Along this line of approach, we present approximate amplitude weights that produce high quality images with less cost. An alternative approach is to compute the traveltimes analytically and compute the amplitude weights on the fly. However, this increases retrieval time significantly. tables are computed in advance when traveltime tables are generated. This involves building tables of in-plane and out-ofplane spreading terms, takeoff and emergence angles for each source and receiver pair in addition to the traveltime tables. Usually this is achieved by incorporating the amplitude weight factors in the Kirchhoff summation. Summary Properly controlled migration amplitudes are essential in amplitude versus offset analysis.

The MPEG4 derivative DivX ) claims to have the capability of storing 10 times as much video as DVD-video, without a loss of quality. New and better encoding formats have been produced and there is a possibility that DVD's will become obsolete just as it becomes mainstream. DVD-video is becoming more and more popular as the cost of hardware and media falls but the world of technology has moved on since the format was finalised.
