.avi import to PPCS3, movie length cut off

[Mike Velte]

I just did a screen capture using Windows Media Encoder 9…4 minutes long and all imported fine into CS3. What app are you using to screen capture?

Mike,

The video files were captured with a capture utility created in-house by one of our programmers. I’m wondering if there is something about how his program is written that is friendly with PP1.5, but not PPCS3. The programmer is looking in to this. I think the question is: what is different between PP1.5 and PPCS3 in terms of how it handles these video files?

Thanks,

Bruce

[Bruce Liddil] “how it handles these video files?”

Obviously, but we dont know what is the difference. Why not use Microsoft’s free encoder or even better, Camtasia 5.

Hi Mike,

For a lot of reasons, we need to use the video capture utility developed in-house. We are doing scientific research in the area of human factors of flight systems that requires requires a lot of custom built systems to interact. Also, we need to turn around long movies (30 to 60 minutes) fairly quickly. Because of that, Microsoft or Camtasia’s product aren’t an option. Actually, we used My Screen Recorder in the prototype stage, but we needed to write our own capture utility to get the functionality we needed. At this point we’re looking at buying more licenses of PP1.5, since we know it works. Might be easier than trying to figure this out!

Thanks,
Bruce

Hi Mike/Bruce

Did you guys manage to find a solution for this?

We have a 1.4gb movie that runs for about 15mins and was recorded using a tool called Morae by Techsmith. It uses its own codec https://www.techsmith.com

We are finding that when we play the avi in Windows Media Player the length is fine. When we import into PPCS3 we get a file lenghth of 43 seconds only?

The output of the properties from PPCS3 are below:

File Path: E:\D
Type: AVI Movie
File Size: 1.4 GB
Image Size: 1280 x 1024
Pixel Depth: 1280

Project Audio Format: 48000 Hz – 32 bit floating point – Mono
Total Duration: 00;00;43;13

AVI File details:

Video track 1:

There are 113 keyframes, 8912 delta frames.
Frame rate is 10.00 fps

Any ideas how we can get round this?

Hi Ben,

Sorry it has taken so long for me to reply. I’ve been out of town.

We never did solve this problem. Our programmers think that Premiere Pro CS3 doesn’t like our codec (developed in house).

Premiere Pro 1.5 doesn’t have a problem, so we switched back to that. 🙁 Not the greatest solution, but gets the job done for us.

I’m sorry I don’t have a better answer for you. If I find further information or a solution, I’ll let you know.

Good luck!

Hi Bruce

Thanks for coming back to me!

We ended up going back to the original usability company and obtaining a copy of the orginal source footage in another format. The problem was caused by the compression and codec used by Techsmith. Adobe Premiere CS3 was not liking it!

Cheers
