For example, if your clip is 30 seconds long and it takes 1 minute to download, give your clip a 33‑second buffer. For short clips, use the following formula: Pause = download time - play time + 10% of play time. While the first part of your video clip downloads, you can display other content that disguises the download. Learn how long it takes to download enough of your video so that it can play to the end without pausing to finish downloading. For example, pillarboxing results when you encode NTSC footage to a PAL frame size. To prevent pillarboxing, choose a frame size of the same aspect ratio as the frame aspect ratio of your source footage. When you select the frame size for your encoding settings, consider frame rate, source material, and personal preferences. Select a frame size that fits your data rate and frame aspect ratioĪt a given data rate (connection speed), increasing the frame size decreases video quality. If reducing the frame rate, the best results come from dividing the frame rate by whole numbers. For mobile devices, use the device-specific encoding presets and the device emulator available through Adobe Media Encoder in Premiere Pro. For web delivery, get this detail from your hosting service. However, if you compress high-motion video, reducing the frame rate has a much greater effect on the data rate.īecause video looks much better at native frame rates, leave the frame rate high if your delivery channels and playback platforms allow. For example, if you compress a clip with little motion, cutting the frame rate in half can save you only 20% of the data rate. If you have a higher data rate clip, a lower frame rate can improve playback through limited bandwidth. Make the clips short to keep the download times within acceptable limits for dial‑up users.įrame rate indicates frames per second (fps). Users with fast Internet connections can view the files with little or no delay for loading, but dial‑up users must wait for files to download.

When you deliver video over the Internet, produce files at lower data rates.
