Let us stay with the Windows 7 Ultimate 64 bit for now with Premiere Elements 12 tryout to which you have applied the 12.1 Update.
a. You have the latest version of QuickTime installed on your computer with Premiere Elements 12/12.1
b. You are running the program from a User Account with Administrative Privileges and also have applied Run As Administrator to the via the Premiere Elements desktop icon.
c. Your computer's video card/graphics card is up to date according to the web site of the manufacturer of the card or the web site of the manufacturer of the computer.
d. The computer is optimized.
1. What are the properties of the source media that you are importing into the project? A fast start to answer that would be to give the brand/model/settings for the camera that recorded the video. Properties readout programs give more comprehensive details in this regard...MediaInfo and GSpot codec utility. We are looking for video compression, audio compression, frame size, frame rate, interlaced or progressive, file extension, pixel aspect ratio, duration. Is the duration of the Timeline content related to the appearance of the workflow issues?
2. What is the project preset that is being set by the project automatically or by you manually.
(See Edit Menu/Project Settings/General)
3. Where have you directed the project's Scratch Disks and how much free space is at that location(s)?
(See Edit Menu/Preferences/Scratch Disks)
4. Please describe the edits that you are making to the Timeline content, especially those when the project problems appear.
Let us start here, ruling in or out the factors mentioned above.
Thanks for the detailed response.
Sorry I didn't know there was a 12.1 update - just applied
a. Yes Latest Quicktime 7.7.5 (1680.95.13)
d. Yes although do you have any specifics..
1. (I will try hereL Camera, Go Pro Black
Is the duration of the Timeline content related to the appearance of the workflow issues : No
Re the properties of the video clips :
Type: MPEG Movie
File Size 1.7GB
Image Size: 1280 x 720
Frame Rate: 50.00
Sounds Audio Format 48000 Hz - Compressed - Sterio
Project Audio Format 48000 Hz - 32 bit floating point - Sterio
Pixel Aspect Ration 1.0
3. The Scratch disk location has some 900GB free
4. Sometimes cutting the timeline content, maybe increasing scale or rotation..
BTW the movie clips are of various sizes, I just chose one, right click, properties
Thanks for the follow up with all the details...
Continuing in the real computer environment Windows 7 64 bit.....
From what you wrote, you have GoPro Black 1280 x 720 @ 50 progressive frames per second video and you or the project have set
PAL/AVCHD/AVCHD 1080p50 as the project preset. So far so good.
When you import one of these GoPro Black clips into this project, do you see no colored line or an orange line over the Timeline
content? Assuming no colored line for the moment...
a. right click the Timeline file, select Time Stretch, and then, in the Time Stretch dialog, change the Speed % to 99. Click OK. Now render the Timeline content which should be displaying with an orange line over its content. After this Timeline rendering is completed (color of line goes from orange to green), is the editing performance same or improved? (The rationale behind this was to force Timeline rendering rather than to apply any Time Stretch Speed% changes to the file.
If the above does not result in improved performance associated with the GoPro Black clip editing, delete the 720p50 from the project and import
a. 1080p25 from the GoPro Black
b. jpg photos
For each of the above, do you encounter the same Timeline freezing episodes as with the GoPro Black 720p50?
In what you have written, the freezing is independent of file size and file duration. Is that correct? Does that observation have limits?
Depending on your results, would you consider posting a sample of your GoPro Black 720p50 via a Dropbox link in a reply in your thread?
As a cross check, I was be glad for the opportunity to work with it in my computer environment of Windows 7 64 bit/Windows 8.1 64 bit on a variety of Premiere Elements versions including 12/12.1.
Please review, consider, and then let us know the outcome. We will go into computer optimization considerations next.
>When you import one of these GoPro Black clips into this project, do you see no colored line or an orange line over the Timeline
We get an orange line..
Re the time stretch - each clip is already "time stretched" to various speeds all faster than normal, some as fast as 3000 if that makes sense
>For each of the above, do you encounter the same Timeline freezing episodes as with the GoPro Black 720p50?
After the right click run as admin the program doesn't fully freeze any more but it is very gittery i.e. when you play the clips (the sped up clips) they don't run smoothly, is it because they are sped up to high ?
Thank you for all you help as ever, we are rendering the project now (it is starting to go green) and will let you know.
Well with your excellent help and support Premier Elements (touch wood) now seems stable.
We have also purchased, so looking forward to creating lots of excellent video
Is their anything specific we can do for optimisation ? Rendering seems to take a long time, but I presume that is down to the required output quality as I can see my processors being hammered.
Thanks for your help.
