In this article we will go over some recommendations for compressing your videos for delivery through the Amazon S3 servers.
A
scenario you might be familiar with is that you have filmed and edited
your content into a package that meets your needs, but once you go to
view your video on your website it takes forever to load or the video
stutters during playback. This problem is not necessarily a bad
encoding, but it could be the result of not encoding your video to a
targeted connection speed.In an ideal world you would be able to load your uncompressed video directly onto the web and end users would be able to view the file. Unfortunately, the quantity of data present along with the bandwidth limitations of your clients, makes this an impossibility at this point in time.
To reduce the data being pushed through your video you will have to perform a compression using a codec, which was covered in our previous article here: More
What to do
- Upload videos in their original resolution - Videos should be uploaded at the highest resolution available. Videos uploaded with a 16:9 aspect ratio will fit the player perfectly. Most 4:3 resolutions are supported, but the video will be pillarboxed in order to fit the player.
- Upload videos with high bitrates - Higher bitrate content will look better on YouTube, simply put. View our recommended bitrates for high quality uploads.
- Upload videos with a 1:1 pixel aspect ratio - Videos without a square (1:1) pixel aspect ratio may not fit properly in the player.
- Upload videos with a supported file format - Supported file formats are consistently more reliable than alternatives.
- Upload videos in original quality whenever possible - If you do not need to edit your video, simply upload the unaltered original recording for optimal quality.
- Upload videos with a identical Audio/Video durations - Audio and Video tracks should begin and end at exactly the same time.
What NOT to do
- No Project files - Project files are not real video files. Common unacceptable project files are .mswmm and .wlmp. Learn how to convert project files to an acceptable format.
- No audio or images - YouTube does not accept audio and image files. However, you can easily convert these files to video.
- No DVD files - Don't upload files types such as .WOB, .IFO and .BUP, which are not actual video files.
- Don't alter videos from the original frame rate - Altering videos from their original frame rates prior to upload may result in an undesirable outcome. For example, videos captured at 24 fps should be uploaded at 24 fps.
- No interlaced content - Your videos should be deinterlaced prior to upload. In your video encoder, you should select Deinterlace or Progressive scan if these options are available.
