Converting 1440 HD Video to 1920

[Stephen McDonald]

I ran some 1440 X 1080p clips from an HX1 through the free Prism Converter and changed them into Xvid at 21 Mbps. This format is accepted as a widescrren format by AVS Video Editor 4 and there, I strung them together and converted them to 1920 X 1080p, at 15.4 Mbps, using their generic MP4 format.

The results are pleasing to me and if anyone wants to use the 1440 X 1080P mode on an HX5V and then convert the rectangular pixels to square ones at 1920 X 1080, this will work. See my Mallard & Ducklings video with this conversion here, on Vimeo: http://www.vimeo.com/11098961 There's more detailed explanations about using Prism and Splash Lite 1.3 for playback, on the Vimeo video page.

I can't seem to get my Windows Movie Maker 6.0 for Vista to work with AVC videos anymore, but WMP 11 plays them and the 1920 X 1080 MP4 conversions just fine. The Windows Live Movie Maker can handle AVC, but the bit-rate for the finished videos is only 8 Mbps and the editing features are limited. AVS Video Editor 4 comes with a large ensemble of A/V programs, for just $60. (U.S.).

I used my shoulder-mount steadying rig for this video. The wind made a lot of noise, but I've recently installed a furpiece as a windscreen, that will reduce this to a low level in the future.

This should be easier for people with slower connections:

Is there any advantage in converting 1440x1080i video to 1920x1080i, if Vimeo or YT simply compress it to 5mbps and 24p? Each recoding entails some IQ loss. If you edit, you might best simply stay in 1440x1080i, export to a format which might coincide withe the YT or Vimeo standard, allowing the sites to upload without recoding trauma to IQ.

I wonder if the 1920x1080 "Full HD" boasted by streaming sites can support anything with much motion without artifacts and judder, since it takes at least 17mbps to support quality motion in AVC at that resolution and perhaps 30mbps in HDV-MPEG2.

I don't think WMM on Vista ever imported AVCHD or h.264 MOV directly.

thanks. can you show us the windscreen?

here's a picture of the windscreen, although it's on another current thread.

The reason for my converting 1440 X 1080p video to 1920 X 1080p, is so I can use it with players and editors that don't properly decode 1440 video in the AVC format and instead display it as a squeezed 4:3-aspect image. Also, Vimeo requires 1920 X 1080, if a video is shown with their new 1080-sized display. In the process of converting to a 1920 video, I also change the format to another MP4 format that WMM 6.0 for Vista will accept. Not all these advanced MP4 formats require as high a bit-rate to show full-quality 1920 X 1080 video.
