Lower resolutions are not affected.Īudio Only: This format will strip the video entirely, leaving just the audio as an MP3. So.if Default doesn't work well for you, your built-in alternatives are:ġ080p: Upscales 1080i to 1080p. MP4 files with H.264 encoding, and most of the Formats we recommend use this container/codec combination. The computer industry has mostly standardized on. Some people will feel that's a good tradeoff some won't.įortunately, the compatability issue is much less of a problem than it used to be, except for older devices.
DECRYPTED TIVO FORMAT CTIVO 1080P
Given the reality of the compression that most cable sources do, this seems a reasonable compromise, but if you'd like to have cTiVo convert 1080i to 1080p for you, we've provided a 1080P Format to do just that however, it will take about twice as long to convert each video and generate almost double the size of the file as a result. The Default Format encodes to a maximum resolution of 720p.
DECRYPTED TIVO FORMAT CTIVO 720P
Now, 1080i is technically higher resolution, but at half the frame rate of 720p (30 versus 60). The computer industry generally thinks this is crazy notably, iTunes will not accept interlaced videos). For historic reasons, the TV industry frequently uses Interlaced video, wherein the odd lines are sent in one group, followed by all the even lines. ("p" stands for Progressive "i" stands for Interlaced. HD TiVo shows will normally be recorded in either 720p or 1080i. Generally speaking, there are tradeoffs between:Ī) the size of the converted video file (usually significantly smaller than the original)ī) the resolution and the quality of the video when displayedĬ) the time it takes to convert (aka encode) the video (ranging from 20% to 300% of the length of the video)ĭ) the compatibility of the video with different devices. Selecting a Format for cTiVoĪs the name suggests, the "Default" Format should work well for most uses, but we've provided many alternatives to handle different situations. We provide a wide range, in addition, you can use the Format Editor to build your own.
A Format stores the information needed to convert to a specific video format. In order to maximize flexibilty while keeping it simple, cTiVo gives you a choices of "Formats".
The video formats used by broadcasters are not very compatible with those used by computer industry so cTiVo needs to convert the vido files that you bring over from your TiVo. Many factors such as resolution (the number of horizontal and vertical pixels), the encoder used, the amount of compression, all affect both the amount of space used and the quality of the resulting video. Video can be stored in many different ways in a file.
