Hi i'm trying to find the best codec and configuration for a 4 min slideshow. The problem is that the project has to be 1920x3240px and the result are huge files! If I use mepg4 the quality decrease notably.I tried with prores and the file are too big
I'm using adobe encoder and quicktime file.

quicktime png video is smallest size you can get and still be 4:4:4. It's only 8 bit though
quicktime jpeg video is lossful quality but at 90 or higher, quality stays good.
h.264 has bitrates you can select from adobe media encoder instead, which gives more options. I'd go above 2500.

what i would do is render each one for 10 seconds. then do simple math, final size = 24x(rendered size). then decide which one you like the best.

I tried in png but the rendering crashes in encoder.
H264 has a max high about 2200 px!

1920x3240 is three 1080p rasters. If this is a multi-display setup, then we should discuss your playback system as these often have particular codec requirements.

[bernat comellas] "I use VlC in a PC."

The maximum height varies according to H.264 profile/level and frame rate:
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

What about rotating your displays and rendering a 3240x1920 movie?

ProRes files may be big, but why is that a problem for playback? ProRes is reliable and works at arbitrary raster sizes. How about ProRes LT to save a little file size?

I tried to render from the other side 3240px 1920px , but VlC crashed.
The problem I have with prores is that I have to work with mac and then move it to a PC . With a fat 32 external hd. the file can't be bigger than 4g.

Use exFAT [link] instead of FAT32 for cross-platform compatibility without the 4GB file size limit.

Yes! I used ex fat 32 and it solves my problem. The size of the file is no longer an issue. I use the prores codec and it looks pretty fine! 18g size.
Thank you for your help.

18GB for 4 minutes? I'm surprised you can play it back in realtime without studdering. Also, media player classic home cinema is better than VLC. It runs more videos, takes 10x less CPU power, and even does post sharpening in realtime.

I'll try with media player. But now is playing without any problem in VlC.
