Image stabilization is probably the major factor in the longer Timeline rendering times, and the complexity of the Timeline content in general needs to be factored in. However, I would need to know the actual details of the Timeline build (effects applied et al) to appreciate fully why 15 to 30 hours for Timeline rendering time.
High end video cards/graphics cards are not your answer in Premiere Elements since they cannot take advantage of the perks of these cards.
Premiere Elements does not support CUDA.
What is the duration of these 6 to 8 files? Is each of them image stabilized using the Premiere Elements Stabilizer?
If you did some insignificant edits to force the Timeline content to need rendering, did not image stabilize the Timeline files, rendered the Timeline content,
a. what does the before and after Timeline content look like at playback in the Edit area monitor
b. what is the Timeline render time?
What is the extent of the camera shake of the source? What drives are involved with the storage location of the source and the storage location of the preview files generated during the Timeline rendering process?
No concrete answers, only questions seeking your answers to get at cause and effect.
thanks for the reply. I'm new to GoPro and Premiere Elements, so I don't know exactly what some of your stuff is.
The video is taken on my dirt-bike, a motorcycle going through trails, woods and rocks. Its unwatchable without stabilization.
The files are all taken as a single ride, single push of the shutter, and I go off and ride for a couple of hours. The GoPro automatically switches to a new recording file when the old one gets to 2.4 GB (which is about the maximum file size for 32 bit file formats.
I copy all of the video clips to the SSD from the GoPro. Then I load them as assetts. Since that it the only disk I have, everything is there. But an SSD should be fast enough to handle swapping, file reading and writing. I don't think that you can get two separate SSDs in a MacBook Pro Retina. It has no optical drive (which you could replace with an SSD in older models)
I'm not against buying Pro if I have to, I'm cheap, and would rather not, but if that will make the workflow feasible, I'll cough up the money.
All of clips (everything) have "Motion" "Opacity" "Stabilizer" and "Image Control"
I actually have no clear understanding of what Motion does vs Stabilizer.
Timeline rendering takes 10+ hours. More if the Mac sleep mode sets in. I have no idea where the rendered files are. Whereever PE defailts them. Still SSD
What is "the Edit area monitor"? Do you mean the smallish video window above the timeline? Sometimes the video looks pretty good, other times the viewing of it lags 30 seconds or more behind the sound and timeline pointer.
I don't think I understand your comment about when to stabilize. I agree that I should be able to work and do edits, titles, etc. without stabilization, and then just turn it on at the end. Or maybe even render it for export and then stabilize that file. But I don't know how to do any of that.
