- If your clips are initially importing with a red line your project preset may be wrong - what preset are you using?
- After applying transitions or effects it is normal for those segments to go red line.
- It doesn't help to use two different types of video in one project. What is your final output intent - DVD or BluRay? If DVD then it would be better to convert your HD material to DV-AVI. See the Gspot link below - analyse both types of clip you are using and post the screen images here.
Install all Windows Updates.
Install latest version of Apple QuickTime (v7.6.7 at time of writing). Even if you don't use QuickTime, PRE relies heavily on it.
- Install most recent graphics and sound drivers from the manufacturers web sites.
- Run Disk Cleanup.
- Run Defragmenter.
- Temporarily disable any anti-virus realtime scanning.
- Use the GSpot Codec Information Utility to analyse the file and post screen image.
- Post back here with the necessary information described here: Got a Problem? How to Get Started
Insanity is hereditary, you get it from your children
Two factors figure in to how long it takes to render a clip: The speed of your computer's processor and the resolution of the original footage.
By nature, AVCHD takes much longer to render than standard DV video.
Also, it's never a good idea to mix video from two different sources in the same project. If you'll let us know which two types of camcorders your video came from, we can recommend a method for converting one type to the other for a smooth, efficient project.
I suspected that there might be a problem mixing the formats but these were the only two camcorders I had and I needed two because I was filming a wedding. I have used two or more 8mm camcorders before without this problem. The two camcorders here are a Panasonic HDC-TM60 (HD internal memory) and a Sony DCR-TRV530 (digital 8MM). The aspect ratios are different but that is acceptable since the ratio simply changes with the edits and isn’t particularly objectionable in this situation. The Computer is a AMD Athlon 64 X 2 Dual Core Processor 5600+ 2.8 GHz with 3 GB ram. The movie is about 1.5 hours long and I have captured about 40 or so clips from the 8MM to insert over a single track running the entire length from the HD camcorder. I have gotten a couple of messages during the editing stating that the resources were low and to save the work and I was wondering if more ram would help there. But what I can’t understand and what is causing me so much grief is why a clip that has been rendered would need rendering again after adding a transition or being trimmed.
Whenever one changes anything in a Rendered Clip, that part will need to be Rendered again. In the case of Transitions, only the area with the Transition will require Rendering. If one adds an Effect, or a PiP, or an overlay Title, then that Clip has changed and will need to be Rendered again. That is because the pixels have been altered.
