How are you playing the video and what format and codec are you using?
The playback speed depends on your system's performance. If it is a weak system like e.g. a notebook with a measly intel core2 processor, not enough RAM and a weak graphics chip to boot, it will be impossible to achieve realtime playback beyond a certain resolution. And of course as Silkrooster already said, the kind of footage would also matter, in particular if it uses a specific compression that may cause further heavy processing to decode it.
Hi, I was just playing it in Photoshop. I'm new to photoshop animation so am just working it out. I don't know what codec means. thanks for your help though.
I would say my system isn't the fastest. I've had my computer two years am running windows 7 and haven't added anything extra to it. Don't know much about computers so not sure how much ram and stuff I was just playing the animation in photoshop, I haven't exported it yet. It's a stop frame animation with about 1500 jpeg images imported into a video layer.
Thanks for your help
Click the windows start button, then right click on computer, this will bring up a window that will tell you how much ram your system has.
Also Start>Accessories>System Tools>System Information will give you all the details you need to know.
As for Codec, That is an abreviation for code/decode it tells windows how to code when saving a video and how to decode when playing a video. Most formats are wrappers (avi, wmv, mov, rt) Each of these have a codec that you can choose from when saving a video, that codec then must be installed on the users computer to see that same video. Most formats come with a basic number of codecs and the creator of the video can purchase other codecs that provide better feature set.
What the codec really does is takes the video and compresses it like a zip file then the user when playing require that codec to uncompress it.
So each codec has its own strength and weaknesses. Some can compress more making a smaller file and perhaps inturn removes more data to get that compression and therefore has a poorer quailty video (just an example)
I am sure you heard of a few codecs if you think about it. mpg, mp2, mp3, mp4, h.264 and so on. Mp3 is the only one I listed here that is for audio only. Yep thats right even audio uses codecs.
What version of Photoshop are you running (check in helpo>system info...) if it is 13.1, you can go to the animation panel, and change the preview to 50% or 25% to speedup replay.
