Hint, don’t use AVI, use Quicktime with the same 8bit or 10bit YUV 4:2:2 attributes and v210 flavour, goes two to three times faster. A 400ft real of film for example, digitized in either 8bpp or 10bpp HD YUV 4:2:2 AVI form, rendered after edit can take up to 12 hours (Windows 7 64bit, multi-core 3GHZ, 12GB RAM) to complete. Of course you can’t escape the final render time for the HD file which can be many hours. All of the edit attributes (stored as meta tags and other functions) of the “edit”, is applied to the uncompressed file, which can then be rendered in its final form with all of the edits, or further tweaked with finer edits. Once the edit is done – this includes the regular raw edits, any compositing, special effects, transitions, titles, synchronizing audio tracks, etc., the chopped up and modified low resolution file is replaced by the higher quality “unedited” equivalent on the time line. It is faster and less frustrating to the video editor. Then an average powered computer platform can work in real-time to preview and help when editing and correcting your work. It simply means that rather editing the large uncompressed files on the NLE timeline, use a lower resolution clone. Did I mention slow as molasses in January. Why do this? Uncompressed HD video files by nature are large and as such present a data handling problem on most computer platforms particularly when editing them.

When working with uncompressed YUV video files like we do at HomeDVD, we use a technique called proxy editing. Posted by Bill on in Tech Tips | 27 comments Offline Proxy editing for High Definition Video
