- Even when video is rendered to a .Mov Lossless file the video is still juddery and appears to be dropping frames when played in Quick Time - VLC is better slightly.
That is to be expected (unless you have a RAID setup for your computer's hard drives). An uncompressed HD file has a data rate that is much too high for your hard drive to handle. If you take that high data rate file into the Adobe Media Encoder and render it into a deliverable format such as H.264, it should play back without issue. If this is the case (and I'm pretty sure it is), this is unrelated to your RAM preview issue.
What version of AE are you running? You say CC, but is it 12.2.0 or 12.1.0? If you haven't yet, update to the latest version; it fixes a lot of bugs.
Also, when you say you've been using AE version 5 and 5.5, do you mean CS5 (actually version 10) and CS5.5 (actually version 10.5) or do you really mean you're using the really old versions?
We have an older mac here which has an older card with more ram (1024 MB) on the card, which takes longer to render the preview (is that due to less system RAM?)
Rendering speed usually has less to do with RAM and much more to do with the processor's clock speed. This is likely the difference.
Is this older Mac running CC or is this the older version you mentioned in the "Extra notes" section?
Have you tried updating the driver for the graphics card? The GPU has very little to do with rendering in AE (except for the Ray-Traced renderer, but that doesn't matter as you don't have an NVIDIA card), but it does have to do with AE's display of its playback.
Hi Szalam, Cheers
I am running: Running After Effects CC 18.104.22.168
- I have just rendered out to a H.264, AAC .MP4 file and it is smoother (but still every 3 seconds stutters a little. - but much better than the uncompressed file so you are right about that being a separate issue to the RAM preview playback)
- For the other version tested on this iMac I have been using CS5.5 (version 10.5) not the old, old versions
- The older Mac is running After Effects CS5, it is an intel 2.93 GHZ Core i7 so has a faster processor (which I’ve only just realised, but is an older model mid 2010) it is slower to render, but plays back at normal speed and will play the exported video smoothly too.. But overall a better machine I think so I'll be swapping with my colleague soon when he's not looking : )
- As to updating the driver - I’m not if I actually can.. The AMD site only has a windows file: http://support.amd.com/en-us/download/auto-detect-tool
- Is it possible to update the driver on a Mac? only seems to have Windows support.
