picture quality; mf 6

Post by drenee »

hi, i am new to this and need some help. i would just simply like to make a slideshow with some pictures we took on our vacation (jpeg) to play on the tv. the pictures are good quality but look very grainy on the tv. Can someone please tell me very specifically what settings i should use on moviefactory 6 to get the best results. If I understand what i've read one of the things is to burn using the slowest speed? I'm really ignorant about this so please help me in words i can understand! :lol:
thanks in advance.

Hi

This is a tricky subject as image size is set by Pixels as the previous post.. However as a very general guide for any of the MF progs. I use an image of not much less or bigger than 500Kb. As I guess you only see file sizes on your jpeg images. The reason I post this is all the MF Programs reduce your images to the given PAL or NTSC pixel sizes hence the drop in picture quality. There is no way round this as standard TV images (unlike HD) are only a very poor facsimile of the original quality.

So if your original images although look good on the PC screen and print remember a TV is composed of only a few lines. Also if being viewed like mine on a new large screen TV the effect is to take a very small image and enlarge to the TV size. Like all enlargements this will show as a poor image if the original picture jpeg is also small. Hence the comment about jpeg file sizes being some 500kb. Hope this helps a bit it is all about understanding the two media and the effect of enlarging an already degraded image to suite a TV output.

To get you thinking about this if you have a photo edit program try a few experiments by reducing the jpeg image outputs (please do not do this to the originals but make copies) and then view at 100%. You will see the quality effect dramatically as you reduce the jpeg image sizes to say 30Kb.

It gets worse when dealing with picture sizes in inches as many professional photographers use 5x7 inches or 10x8 inches etc image sizes. So I ask my pro photographer to cut his image file sizes to 500kb approx to keep the quality to a max for the slide show.
I have made many good slideshows using the MF family from 3 to 6.

Hope this helps, if not ask again.

Best

M :D

I suffered from fuzzy TV slide shows for years through following the use upper/lower fields suggestions of experts.
One day I accidently made a DVD using the framebased setting, and voila - no more fuzz.

HQ 4:3 (Dolby Digital)
setting TV MPEG files
24 bits, 720 x 576, 25 fps
Frame-based
(DVD-PAL), 4:3
Video data rate: Variable (Max. 7000 kbps)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

GQ 4:3 (Dolby Digital)
Video data rate: Variable (Max. 4000 kbps) works too.
