When encoding for upload to YouTube, playability isn't an issue, so Louden recommends an IDR frame every third keyframe.ĭitto for adaptive B-frames, which improve quality, but some producers avoid because they can cause playback issues on some devices. However, IDR key frames are larger than normal key frames, which is less efficient compression-wise. For example, the rule of thumb when encoding for playback is that each key frame should be an IDR frame. This relates both to data rate and encoding parameters like IDR frames and adaptive B-frames. Louden also noted that because it's all about quality, you don't have to worry about playability, which frees you to create a file that might not play smoothly on many computers. The higher the input quality, the higher the output quality. Second, your job is to provide the highest possible quality file to YouTube, since, as we all know, video is a garbage-in/garbage out medium. First, don't try to match YouTube's output so it won't re-encode your video it always re-encodes. Telestream Episode product manager Kevin Louden started by noting that YouTube re-encodes all video uploaded to the site, which has several implications. Let's start by chatting with our experts.

Seasoned YouTube posters might also find value in this article, where I synthesize YouTube's encoding recommendations, advice from several compression experts, a look at presets from common encoders, and the results of my own tests, to provide specific advice about how to configure your video for optimal quality and the most efficient upload time. If confusion about the best way to post videos on YouTube was part of the reason, you're reading the right article. At this point, if you're not posting your videos on YouTube, it's more appropriate to ask, "Why not?" Many companies, including Deloitte and IBM, use YouTube to host the videos posted on their own corporate websites. When YouTube started, poor video quality and a young audience caused many organizations to ask, "Why bother?" Today, many Fortune 100 companies have their own corporate YouTube channels, as does the AARP. In 2011, YouTube had more than 1 trilllion views, or around 140 views for every person on Earth. According to YouTube's FAQ, over 800 million unique viewers visit YouTube each month watching over 3 billion hours of video. According to one source, in February, 2012, YouTube accounted for 75.9% of all visits to video-related websites, with AOL Video and Hulu tied for second with 2.8%.
If we didn't live with YouTube's scale on a daily basis, and somehow seemingly take it for granted, it would almost be too big to imagine.
