Little Test-series HD-Output

[stardealer]

I have created one simple slideshow with one single image and created MP4 files, no sound.

All MP4 files where created in 1920x1080, lenth of the show is always 34 seconds

Here are some observations regarding size and quality that I have found:

Version 1: small (Zoom 50%) still image without fade-in/out

Settings: high quality, 30p

Size: 1,7 MB

Version 2: small (Zoom 50%) still image with 1,5 sec fade-in/out

Settings: high quality, 30p

Size: 17,3 MB

Conclusion: compression does an impressive job, when nothing is changing on the screen

(just kidding, but now move on to the [maybe] more interesting samples)

Version 3: image (Zoom 100%, full-screen) floating from left to right over 30 seconds with fade-in/out

Settings 1: quality 100%, 30p

Size: 15,6 MB (why this is smaller than Version 2 with the non moving image I can't explain)

Settings 2: quality 100%, 60p

Size: 31,3 MB

Settings 3: quality 60%, 60p

Size: 9,1 MB

Settings 4: quality 30%, 60p

Size: 4,5 MB

Quality observations: 60p delivers smoother animations than 30p (may depend on output medium), quality 60% with 60p delivers smoother animations than 30p without noticeble loss of picture quality and smaller files, quality 30% with 60p delivers smoother animations than 30p but with minor noticeble loss of picture quality and very small files.

Seems that I will use 60p with 60% quality setting (and somtimes when size is crucial 30% quality) when creating MP4s from now on.
