Streaming Media Production Tips

For recommendations regarding production, editing and video quality, please review the Best Practices section.

From lighting to camera work to video resolution, there is plenty you can do to make sure that the compression consultant has the best possible footage with which to work. Most filming locations, although perfectly suitable for human beings, are not that well-suited for filming. Lighting continues to be a sensitive area for streaming, but color is no longer an issue due to expansive modern codecs.

Motion, however, is still a very large concern. Video codecs use motion as the primary determinant for deciphering what is most important in a scene. This means any excess motion during a video production will result in a lower-quality streaming video. Any unnecessary motion should be avoided.

Streaming media rarely takes up more than a quarter of a screen, which means the video has to make more economic use of available screen space than it would in a full-screen dynamic. Typically in a streaming media movie, you may want to frame tighter on a person's face to capture the most action and emotion.

There are several things you can do to ensure that your final product leaves an impact. Though these are not binding rules, they can save your final product from looking cumbersome and sloppy.

When moving from analog to digital format in the capture stage, there are some things you can do to help streamline the process.

  • If possible, try to use digital tapes to record the media (DV/Mini DV instead of VHS).
  • Try to capture clips in segments rather than capturing all of your footage at once. Sometimes sound may get out of sync if the computer is trying to read too much information.
  • You can avoid the "hissing" effects of poor-sounding audio by incorporating the use of a microphone or by recording in smaller spaces.

Tips for Advanced Users

In the event that you have streamed before or are confident in knowing enough of the information already supplied, you may find this section more helpful. Here are more specific details about the compression software.

Deinterlacing
The deinterlacing feature can make your video look better by removing interlacing artifacts caused by the two-fields-per-frame nature of conventional video.

Telecine removal
Telecine removal maintains video quality by removing the extra frames that are added (3:2 pull down) when film (24 frames per second) is transferred to video (30 frames per second).

One-Pass Variable Bit Rate (VBR) compression
One-Pass VBR compression reduces processing time to non-VBR standards while delivering only slightly lower quality than Two-Pass VBR compression.

Two-Pass Variable Bit Rate (VBR) compression
Our software supports Two-Pass VBR, which produces higher quality video than standard compression while only adding slightly more processing time.

Aspect ratio
You can keep the original format (4:3) or (16:9) depending on the capture device. However, the software can also simulate both views to accommodate a full-screen or cinematic viewing area.
