How do I set up my Windows system so I can properly play back video with the 64-bit version of Live?
- Liveバージョン: 8.4b9 - 9 (64-bit)
- オペレーティングシステム: WIN
A digital video file (e.g. .mov, .mp4 or .avi) basically is a container that encapsulates one or more video and audio streams. Each of these streams again is encoded using an industry standard codec (e.g. mp3 or aac for audio, H.264/AVC or MPEG-2 for video).
To be able to play back such a video file on a computer, there must be installed both a suitable demuxer to read the container file and a matching decoder for each audio and video stream.
The most frequently used codec with acceptable performance and good quality is H.264 (also called AVC). As container file format, the best choice is .mov (Quicktime) or .mp4.
The 64-bit version of Live can use any DirectShow compatible demuxers and decoders that are available on the computer, but on a fresh Windows system, only a limited number of video codecs is installed by default. That's why you might need to install additional codecs.
In practice, some decoders are more suitable than others. Live is tested with the following two solutions that you can install on your machine to enable proper video support with the 64-bit version of Live.
Free solution with good performance and a wide range of supported codecs and file formats:
- Demuxer: Haali Media Splitter (also known as MatroskaSplitter, download directly)
- Codec: ffdshow 1.2.4422 (H.264, DV)
Lowest resource usage and high responsiveness, needs to be purchased:
- CoreAVC 3.0.1 from CoreCodec (H.264)
Only with properly encoded video footage, fluent high quality playback is possible.
When it comes to encoding uncompressed video, it is recommended to use as many Keyframes as possible (optimally encoding with Keyframes exclusively), which will noticeably enhance responsiveness and lower CPU usage.
This can be enabled in the settings of the video encoder when rendering the video. If you do this with Live, you'll find these settings in the "Export Audio/Video" dialog accessible after enabling "Create Video".
