In any case, it is usually best to make your comp to a losless format (QT none, or TGA sequence, etc.) and then compress your video with Media Encoder. You can get a better quality if you encode 2-pass VBR with a maximum bitrate set to what you calculated previously. So, if you want a 10 sec clip to be 15 MB (excluding noise), divide 15 MB at 10 s and get you 1.5 Mbps bit rate, or 12 Mbps. The file size is directly related to the baud rate at which you are encoding, not the size of the image or images per second. I thought that in the past my QT h264 renders were perhaps double the size of my wmv file renders more leap of 15 x. same timeline, pixel dimensions and speed = approximately 150 MB and a similar quality. The quicktime h264 out much more than expected. Some of my clients have flip for mac, so I have to make a quicktime. Project in progress - my wmv renders out approximately 10 MB and of reasonable quality that is excellent. I wonder if someone can recommend a codec quicktime good for very small file sizes, for overview makes. Frustrating, I know.Īfter effects cs5 - quicktime h264 of very large file size So everyone on Yosemite will have to argue politely ask Apple to fix the problem or wait until the update of EI. According to the people at Adobe, the updated version of the AE with the new preview is supposed to go out to the 'spring '. The problem is that the fix is to completely rewrite the code from the heart of EI. Until Apple releases a fix (if they ever will be), you're pretty stuck if you can not go back to the Mavericks. It is a problem to Apple they changed stuff in Yosemite. If you are using a different operating system, you will not have this problem. Even if you try with CS6, you will still see this problem. It is a known issue with Yosemite on all the versions of AE. Is there a way to solve this problem on my side or flat? Why is this happening? It was something that worked perfectly for years and now does not work. You must wait until it passes at the end to watch the start. Playing audio but the picture is frozen and no shortage on the beginning of the preview. When I visited a working space, there is a 22 frame delay before the picture becomes visible. Last year only preview rendering After Effects ' seems to have been much worse. New version after effects now have a very poor delay with render preview Preview RAM CS5 offers excellent performance. In short: on the same machine, RAM of AE CS5.5 preview offers terrible performance. In my preview, I tried setting my default resolution to "Auto" to "Quarter" without any difference. On my screen magnification ratio setting, I use 25% and my Resolution/Down sample is on the quarter. Yet once, no matter what I set it to, I have the same problem of performance. Currently I have MP'ing activated with allocation of 1.5 GB per background CPU and real processor used is 4. I tried different settings for multiprocessing, which translates the same less-than-2 fps previews RAM. Reserved for other applications of RAM: 4 GB My settings for CS5 and CS5.5 are similar (and I tried many variations in my attempt to solve this problem).įast previews: Adaptive resolution limit 1/4Ĭompatible OpenGL and two sub-options for active OpenGL. When I create a similar test inside the CS5 project, it creates the RAM Preview almost instantly and displays good real-time (23.976 fps). I still have AE CS5 installed and it gives me strong and predictable results with RAM Preview. I created a project of 1080 p 23.976 with two solid layers simple and retouching position and scale values to one of them without other effects to be switched on. It's even with the simplest compositions. Problem: RAM Preview in CS5.5 give me less than 2 fps (Yes - two images per second). My system: Windows 7 Professional, two-processor Intel Xeon X 5650, 12 GB of RAM and a NVIDIA Quadro FX 4800. After Effects CS5.5 - Performance very serious issues w/RAM Preview
