Stuttering with transitions

I created a short video with MM2 using fade, dissolve,
snow wipe and snow burst (both of the later from the
winter fun pack). With the video converted to a .wmv
file, the video stutters in the middle of the transistions
(except fade).

Does anyone know what might be causing this to occur?

Thanks,
Eric
 
Is the stuttering with Audio, Video or both?

There is a known and annoying bug in the software that
causes glitches in the additional audio (EG - added MP3
audio track etc) when transitons are running.

I have spent some time trying to get some kind of
feedback in this group that MS knows about and is working
on the problem, but to no avail.

PapaJohn has made sure that they are aware of the problem.

Look back through the history for other postings from
myself and you'll see some quite in depth discussion on
the problem.

Also - have a good look at papajohn.org for any info in
the troubleshooting section.

Personally, I have not had stutters in anything other
than the extra audio track during the transitions, so one
way around the problem for me was to record at DV quality
*without* the extra audio, re-import the whole movie
(which now includes the transitions) and then put down
the other audio tracks.

As it turns out, this was still of no help to me, as
there is another bug in the DV (PAL) output that causes
every 3rd or 4th frame to be incorrectly (fuzzy) rendered
causing the video output to look dodgy. As I need to
record it twice, by the time it's done virtually every
second frame is blurry.

Dunno if this helps, as maybe it's not the problem you
are having, but any informaiton is better than none!

For future posts, include as much detail as possible. It
helps to know more if people are to recognise the problem
as one they have seen..

Hi there,

It may interest you to know that I have never had the stuttering you
mention in either the primary or secondary audio tracks. I doubt that this
is a bug, rather an incompatibility of perhaps hardware/software. See the
opening video page on my web site at www.the-kellys.org for an example of
audio on secondary track with lots of effects on the video track as well as
cross fading between 5 or 6 different audio clips

If you are referring to my posting, I must ask: Have you
tried at DV quality, PAL output?

I have mentioned in my previous postings that it only
happens at DV quality output...

Have a quick look through my previous postings in this
group and I think you'll agree that there is a bug in the
software, or at the very least, the CODEC, which came
with MM2, so still the software...

Look out for my complete wrap on what I have found
regarding this problem in the next week or so It'll
include BUG REPORT in the title. There will be 2. One for
the glitches in additional Audio during transitions and
one for the bad rendering of every 3 - 4th frame on DV
quality output for clips over a certain length.

I actually have workarounds for both, but they are both
miserable solutions to something that I could not imagine
being anything other than a bug after the testing I have
done.

Thanks.

Nathan.
 
Hi there,

John -

Yes, I do all of my output to DV-AVI. Have never had a stutter. Did you see
the video I referred you too ? It was cut down by WME to its size on the
web from a 720 x 576 DV-AVI file. If you continue on that page and look at
all of the other video's, also reduced from their original DV-AVI parents,
you will see loads of transitions and audio transitions...without a single
stutter.

No, I can not agree about this being a bug in the software. There may be an
issue with the software on your system that is causing this, but that does
not mean that MM2 has a bug.

If there were a bug, then the many people who do not have this problem
would have to, by accident, do something wrong, that caused the bug to
disappear. You should remember that in general the few dozen people you see
in here with problems are a very small sample of the actual number of
people using this software.

Yes, well as I have already said, this must be a problem with your system,
either software or hardware or both.
I actually have workarounds for both, but they are both
miserable solutions to something that I could not imagine
being anything other than a bug after the testing I have
done.

Well if the testing was within the environment where a condition exists
such that MM2 does not function as intended then all you are doing is
re-affirming that the condition exists on your system. Its almost like
saying "All horses have four legs, I have two legs, therefore I am not a
horse"

Consider this. When you are doing your testing you are performing an
"Empirical Analysis" which results in your creation of a "Hypothesis" that
then becomes a statement of fact. No problem there at all, its how we all
live. But, as soon as one single exception to that statement occurs (In
this case all of the people who do not have this problem) then the
statement as it stood has to be modified because it is no longer valid.
There is a lot more to that argument, so cutting it short....your belief
that there is a bug in MM2 that causes a stutter is no longer sound (pardon
the pun)

If it will help, I made this offer to someone else in here, I will take a
video of my screen at all important stages of the production to show that I
do absolutely nothing special and that the result will be a DV-AVI video
with loads of transitions in Video and Audio and that there will be no
stutters in the output.

All the best......John Kelly

Okay folks, here we go: first off, video processing will bring nearly any PC to its knees. Without adequate resources your PC may not be able to go through a video-transition-video and audio without some hiccup. This is because of inadequate System Memory which causes Page Filing. Page Filing is when your processing runs out of System Memory (RAM) and has to write/read to the Hard Drive. This takes a bit of time and thus you see or hear a stutter in the playback. The solution is to bring System Memory to between 500MB-1GB or more. Also, if your Processor is slow, stuttering can occur while it tries to play catch-up with the demand. It's All Data: 1's and 0's. Video has data rates that can easily exceed processor, memory, video card, sound card, bus speeds, etc. Upgrade to all you can afford. Another solution is to burn a cd or dvd and see if the stuttering is there on playback. In all likelyhood, the stuttering will not be on the disc.
