MSP 8 Bug: Thumbnails fall out of sync with actual video

[tyamada]

You folks that are having sync problems seems related to the speed of your processos. AMD is slow with AVI files and both of you are using what are 2.0 Gig CPUs.

Devil is using a processor that is 1Gig faster than that and he and I don't have that problem. My processor is 3.02 Gig. We also have Processors that Hyperthread (two processors to handle workload).

I don't get what you try to say?
I have Intel, not AMD, BTW my also with HT.
Do you think my bug is happening just because of difference between 2.8 and yours 3.06 MHz?
Did you try to reproduce what I was describing or it's just your guess?

ddima:
I never use avi files just mpg and my system has 3 gigabytes of memory, you might want to install another 512 mb of memory, there is a performance gain with the extra memory, it depends on what Asus mother board you have and if it uses dual channel memory. I noticed a performance gain when I went to 1GB of memory, there isn't any noticable performance gain going from 1GB to 3GB.

1. I've no intention to be acerbic, but I try to be brief.

Just making sure. I've been around bulletin board systems longer than most, so I know what 2D posts can do to a message.

2. Charlie Hill's book has been available in print for a few weeks now. It is excellent.

I'll have to check the local bookstore. I've been waiting for Ulead to get them in stock under the apparently false assupmtion that they'd get them in stock before bookstores since it's their product.

I'm not saying you're wrong, because I have occasionally seen in the past a difference and I'm reasonably sure I have seen it in earlier versions, as well as 8.0. All I'm saying is that I wasn't able to see it with 20 minutes of testing. Can you give a sure-fire way of creating it?

Sure. Load a clip. It happens every time on my system.

However, I do not have the same version on MSP8 installed as you do. I don't think that is an issue though, because there is no mention of the problem in the documentation. Notwithstanding, I'll ask for confirmation.

Again, it's not a big deal. Just one of those things to add to the list to be fixed if possible -- assuming that it can be properly replicated.

This is complete, utter nonsense. You've apparently been successfully brainwashed by Intel's megahertz propaganda.

There is far more that goes on behind the scenes than raw MHz to make a CPU comprable with another. Ask anyone who has worked with building his own systems about the inner working of motherboards, its components, and peripherals. Better yet, ask anyone who's worked with AMD, PowerPC (IBM), or SPARC (Sun) about the accuracy of comparing systems based on raw MHz. I'm not going to turn this into an AMD vs. Intel thread, but the fact that you're even trying to make raw MHz an issue shows that you know nothing about which you speak.

First off, this sync problem never manifested itself with previous versions of MSP on this very same AMD processor.

We're also not talking about real-time synchronization. We're talking about displaying the frames on the editing board. If it was a matter of CPU utilization, it would take longer to render, but it would still render the same way. The improper display of a frame comes down to MSP improperly displaying the contents of the first frame of the clip. Improperly showing the contents of a datastream - regardless of how long it takes to render that datastream - has nothing to do with the speed or architecture of the CPU.

If you would check the internet it is a known fact that AMD processors are slower with AVI files than Intel, not proproganda. I have my on company and put together over a thousand computers so don't speek before you know the facts.

I don't dispute that Intel is faster than AMD when it comes to video rendering. I've seen the results on Tom's Hardware and others as well.

What I will vehemently dispute is your statement ("You folks that are having sync problems seems related to the speed of your processos.") that using an AMD, because of its slower throughput for video rendering, is somehow reponsible for MSP incorrectly displaying the wrong frame image when in thumbnail or film strip modes. Displaying the wrong thumbnail is 100% related to the interpretation of the contents within the datastream. It has zero to do with the CPU that is being used. That's what I was replying to.

And I'm supposed to be impressed? That's like saying that because you've changed a thousands spark plugs you know how to diagnose and fine-tune a transmission. Knowing how to put PCs together does not equate to knowing the intricacies of PC hardware and their component intercommunication capbilities. Oh, by the way, I've been building PCs for family, friends, and work since 1990, so kindly spare me the holier-than-thou dogma.
