If you could explain the behavior in detail, it would help.
"Screen Flicker" is very generic.
I will try to explain. The video starts with a freeze image (map with travel route) on the screen. That’s OK. Then the zoom starts into the image for details. In this moment, the image change between dark and light in a frequency of about 4 times or more per second. The image jerks. Details don’t move continuously. The same happens, during a camera turn. If the zoom or the turn is finished, the image looks very well.
Were both versions of PrPro on the same computer? Did the computer get any sort of an upgrade, say a wipe and reinstall of a new OS?
The reason that I ask is that there are several versions of the H.264 CODEC. Some users have found similar issues, when using the Apple version. Most have had better results when the go with the Lead, or the MainConcept versions. If you had another H.264 CODEC installed, when using the older PrPro, things could be different. It could also be that you had a better one, and along the way, one that was not quite so good was installed, and seized the priority of the better one.
Just thinking here,
CS3 runs on an older 32-bit Windows XP Professional Computer, CS5 runs on a new Windows 7 Home Premium, 64-Bit Computer. Now I installed the CS3 on the Windows 7 Computer and I tested the export of a short video with CS 3 and CS 5 on the same Platform.
Both versions are exported with same settings:
- Format: H.264
- Standard: HDTV 1080p 25
- Video-Codec: Main Concept H.264 Video
- TV norm: PAL
- Frame width: 1920 pixels
- Frame height: 1080 pixels
- Frame rate: 30 fps
- Scan type: progressive
- Display aspect ratio: 16/9
- Profile: high
- Level: 4.1
- Bit rate coding: VBR, 1-Pass
- target bit rate: 12
- maximum bit rate: 18
The result is:
CS 5: Zoom problems are continuing. File size: 54 kB.
CS 3: Not any problems. File size: 73 kB
Using the same parameters the file size is different! Maybe the problem is here, but I don’t know.
