Still Image File Size for HDTV

I'm in the process of creating my first movie
incorporating mostly stills, but also some movie clips,
and sound files for background effect.

Is there an ideal still image resolution when the
intended output is to High Definition TV?

I assume 16:9 format, but what about PPI?

Does TV screen size enter into the equation?

Tiff or JPEG?

Thanks
 
1280x720 pixel is the lower high resolution size and 1920x1080 the higher...
work just with the total pixel dimensions, not PPI. No, TV size doesn't
enter into it, but the resolution capabilities of the TV does.

Unless you can use WMV files at these higher resolutions on your playback
units.... standard DVDs will be constrained by the MPEG-2 files created from
your Movie Maker project.

Thanks for the quick response.

How about the issue of TIFF vs JPEG. Since PREG images
are already compressed, does the MPEG-2 format cause the
file quality to lessen even further?

Am I, therefore, better off using an uncompressed format
like TIFF?
 
Hello there,

The procedure you should adopt is as follows...

1) Using an editing program crop the image so that its dimension conform to
your target ration...if you want wide screen use a cropping tool set to 16:9 or
4:3 for old fashioned TV

2) Using the same program resample the image so that its height conforms to the
height of your target image...so if using PAL DV-AVI resample so that the
height of the image is 576 pixels. The width will take care of itself if you
have done step one above

The reason for this is that Movie Maker makes a poor job of resampling stills
and has no abilities to crop.

If you want a video editor that WILL do the above as well as a lot more try to
find the free version of MovieXone...its often found on publications like PC
Utilities.....

With regard to whether the image should be A TIFF or JPeg etc....it is far
better to do all of your preparation and eventual use in Movie Maker by using a
standard BMP file. Such a file has no compression of any kind and will not
therefore suffer from Compression and re-compression fatigue causing additional
artifacts in your working image. In fact the same argument applies to
Video....when editing always use the highest quality, in the case of Movie
Maker that is currently DV-AVI. Much higher High Definition is possible with
the other program I mentioned...MovieXone or its very BIG brother MovieDV
Version 6....you can get that from the German site www.aist.de the program
works in a variety of languages, gives 11 Video and Audio tracks with some big
league effects/transitions and editing options.

Hope this helps.
