Premiere 6.5 (PC) constantly creating video and audio bugs when rendering AVI files

Discussion in 'Amateur Video Production' started by François Arsenault, Jan 5, 2005.

  1. Hello everyone,

    I've been using Premiere 6.5 (for PC) for over a year now and have created
    several videos with it. I recently got a new computer. Before that my
    computer was just powerful enough for Premiere, but barely. I had many
    problems, like Premiere would crash randomly during capture (usually after 5
    to 45 minutes), it didn't always succeed as rendering a clip, it created
    brief but annoying video glitches, especially when I used transitions or
    messed with brightness/gamma/contrast/etc., that sort of thing. It could be
    infuriating, because I often had to try again and again. It made simple jobs
    take a lot longer than they should. But in the end it worked.

    I thought a new, more powerful computer would take care of my problems. I
    was wrong. Oh, the job gets done much faster than on my old computer, and I
    can capture as much as I want without Premire crashing. But it still fails
    rendering jobs for no reason from time to time, and there are still video
    bugs. At least I don't have to wait as long before starting over. Still, it
    appears that the problems I've been having all this time aren't all due to
    my processing power. It's like Premiere itself isn't very stable, even on a
    fairly powerful computer. Which is a shame, because otherwise it's a very
    nice piece of software that has served me fairly well until now.

    Now, I could live with this imperfect situation, but a few days ago things
    took a turn for the worst. For some reason, Premiere is now totally
    incapable of creating an AVI clip without inserting not only video, but also
    audio glitches. For video it's like big blotches of large, multicolored
    pixels. It only lasts a fraction of a second, but it's enough to ruin a
    clip. I used to get those before, but now it's constant. As for audio, it's
    a loud PSSSSHHHHH! sound that can last for as long as a second. I used to
    have those before but very rarely, and usually at the very beginning of a
    clip. Now I can't create a 3-minute AVI without getting a video bug, an
    audio bug, or most often, both at the same time. No matter how many times I
    try to produce an AVI, I always get at least one bug like this. I once
    worked 8 hour on a single damn 4-minute clip, and it never got it right. By
    the way, the glitches are really produced when a clip is rendered from a
    captured AVI. They don't show in the original captured footage. Also, while
    these tended to happen right after a transition on my old computer, they can
    now appear anywhere.

    Another problem that I didn't use to have is that when I capture from my
    camcorder, every few minutes the sound gets dropped for a single frame. This
    affects the original captured footage, not just the rendered clips, and it's
    random. It's extremely brief of course (1/30 of a second), but it's
    noticeable. I'm quite sure it's not caused by my camcorder, and I've never
    experienced this until recently. It's not a video killer like the video and
    loud audio bugs, but it's somewhat annoying, and it's an additional sign
    that something is very wrong with Premiere or my computer. I mean, this
    started happening pretty much at the same time Premiere started being
    incapable of rendering an AVI without problems.

    I should point out that I didn't have these problems when I changed my
    computer. For the first several weeks it worked just fine. Well, with a few
    problems like I said, but not constantly like now. It seems to have happened
    a few days ago. Clips that I produced successfully a couple of weeks ago are
    now bug-ridden if I try them again.

    I've tried everything I could think of to get around the problem. I tried
    producing a clip several times from the same footage, hoping it would manage
    it at least once. I tried recapturing the footage from the MiniDV tape and
    rendering a new clip from the freshly captured material. I tried building
    clips a bit at a time. I tried producing a clip with glitches and then
    reproducing it after splicing out the glitches. I tried sending a timeline
    directly to my camcorder without producing it first. I scanned my computer
    for viruses. I defragmented all of my partitions. I uninstalled and
    reinstalled Premiere. Nothing works. I still can't produce a single AVI file
    with Premiere.

    I've no idea whatsoever what could be the cause. I mean, until a few days
    ago I could still use Premiere just fine. Oh, it wasn't 100% reliable, but
    it still managed to work eventually. What happened that screwed up Premiere?
    Or, what happened to my computer that makes Premiere even more unstable than
    before all of a sudden? I don't remember doing anything special to my
    computer recently. And why would Premiere in particular be affected like
    that? Like I said, I tried reinstalling it, thinking maybe it got corrupted.
    But it didn't fix the problem at all. It's like my computer doesn't like
    Premiere anymore.

    It's funny, I never had problems like this with my old VideoWave4, which I
    used before I got Premiere. Oh, VW4 used to annoy me for other reasons, but
    it never failed to produce an AVI and never created video or audio bugs.
    It's still working just fine (to a point), and at the moment that's what I'm
    using to produce short clips until I find a solution to my Premiere problem.
    If my computer doesn't have a problem with VW4, why would Premiere 6.5,
    supposedly a significantly more advanced program, would give me so much
    trouble? And I don't just mean the catastrophic situation I'm experiencing
    now. I also mean the fact that it was never totally stable. I've never been
    able to apply brightness/contrast/etc changes without problems, for
    instance, though VW4 can.

    Sorry about the length of my post, but I didn't want to forget anything
    potentially relevant. Oh, while I'm at it, my current computer is an Intel
    3.0 GHz with 1 GB of RAM and and a Radeon 9800 Pro card (128 MB), running
    under Windows XP. Obviously the problems aren't due to lack of power.

    Anyway, I'm very worried that I may never figure out what's wrong and may
    have to switch to another program, even though I'm sure there isn't anything
    wrong with Premiere per se. But I'm hoping someone may have an idea what's
    going on. I'd be very grateful for any advice. Thank you in advance.

    Francois

    P.S. I tell you, there are times when I really wish I were a Mac person.
    Video would be so much simpler.

  2. Except that you didn't mention what you are using to capture video
    (are we to assume it is the Radeon?) Frankly, all the problems you
    are having sound much more like hardware problems than software.
    Many of us have used Premiere for many years through several versions
    on dozens of computers and have NEVER seen such artifacts, even once.
    I'd bet that if you were capturing video with something like the
    ultra-reliable Canopus ADVC-100 and a cheap $15 Firewire card,
    you'd likely see all these artifacts disappear.
    Don't kid yourself. The Mac/FCP crowd live in their own little
    private hell. Pride keeps them from talking about the problems
    out of school. Ask "nappy" who hangs around these newsgroups.

  3. I capture through the Firewire card. Is that wrong? I'm not even sure how to
    do it through my video card. Never tried, anyway.
    I'd like to point out that I'm not, in any way, putting down Premiere. I
    know it's an excellent piece of software, and I know my situation is an
    exception. I really wish it was working normally for me, because I want it
    to be my main video editing tool. But no matter how good Premiere is and no
    matter how I like it, it doesn't change the fact that it doesn't work
    properly on my computer right now. I don't know why, I know it's not normal,
    but it's the truth, and I'm trying to figure out what the problem is.

    Also, if hardware is the problem, how come I had basically the same problems
    with my old computer than with my current one? It was an entirely different
    system. I didn't recycle a single component. Well, besides my Pioneer A06
    DVD-RW burner, but how can that be the source of the problem? And why did
    the problem suddenly become a lot worse a few days ago?
    I'm not quite sure how that would fix the problem, since capture is usually
    the least of my problems. Oh, it used the be a bit quirky on my old
    computer, but it worked in the end if I was careful. And yes, I do have a
    tiny little problem with the audio for single frames being dropped from time
    to time now, but it's very minor, and I didn't have that until a few days
    ago. Capture isn't my main problem. It's rendering. I mean, I don't see how
    the capture process can cause glitches when I create an AVI file.
    Oh, well, I guess we all have our problems, including Mac owners. Though
    they really don't talk about them much, do they?

  4. What capture solution are you using? And in regard to your statement
    concerning using a Mac for editing here's a little clip for you.
    http://digitalvideosolutons.com/video/usingamac.wmv Detail your capture
    settings and your export settings. I personally have never heard of having
    these types of problems, especially on two different systems.

  5. I'm not sure what you mean. Do you mean what I use to capture footage from
    the camcorder? Just an ordinary FireWire card. But I'm not sure what capture
    has to do with my main problem, which is the glitches that appear in the AVI
    files that I render. I can live with having occasional problems capturing
    footage (though I do wish I ddin't have any). It's the glitches that really
    makes using Premiere an impossibility right now.
    Oh, uh, I'm very sorry, but the link doesn't appear to work at the moment,
    though maybe it's just me.
    Unfortunately, neither have I, which makes an easy fix next to impossible.
    No one seems to know what's my problem. Oh, I get some good suggestions, but
    no one has been able to tell me "Oh yeah, I used to have the very same
    problem. Here's how you fix it".

    Haven't had the exact same problem, but glitches I have seen in much
    the same way as you, it seems.
    I was making 768x576 PAL MJPEG video files with Premiere 6.5, and they
    would often contain random 1-2 frame glitches with garbage.
    I remember cutting and rerendering and rekeying and despairing.
    The glitches disappeared, and have never come back, when I changed
    the audio from 22050 kHz to 44100 kHz.
    I really don't know why that happened, and I can't tell you how to fix
    your problem, but it might be a good idea to try different
    codecs/settings and see if the glitches persist, if you haven't
    already.

  8. HAHAHAHAHAHAHAHA!!!! Oh man, that was absolutely hilarious! I feel much
    better about using a PC now. Thank you so much for referring me to this
    great clip!

    Take care

  9. Exactly! In my case it's mostly when rendring AVI files, but what you
    describe is exactly what I get, at least in terms of videos glitches, as I
    also get audio glitches now. It's very short, about 1 or 2 frames, a big
    blotch of big multicolored squares (garbage indeed). Even though it doesn't
    last long it's still enough that you can't miss it, and it's enough to ruin
    a clip if you intend to do something serious with it. Actually, I'd also
    find it very annoying even if it were only for my personal use. I'm
    currently trying to produce material for sale, so the glitches aren't very
    good for the professional image. I simply can't tolerate them. They used to
    happen only occasionally (except when modifying the picture in a significant
    way, like adjusting gamma or something), but now it's all the time. Loud
    audio static glitches too.
    I did the same. Before my problem got worse a week or so ago I mostly got
    such glitches when modifying the footage is some way, like when adding
    transitions or messing with brightness/contrast/etc. You know, stuff that
    made the processor work a bit harder than basic rendering. With transitions
    it typically happened during or right after a transition, like that
    particular addition was too much for my computer. With picture adjustments I
    had a very hard time producing a clip lasting a fewe minutes without a video
    glitch appearing at random. So what I did was take the resulting clip, cut
    out the few bad frames and splice everything back together. Since no other
    modifications were involved my computer usually managed it. Some times you
    could notice the missing frames, especially when it was 2 or 3, but that's
    something I could live with. Just a slight skip. Much better than getting it
    completely right after 10 agonizing hours of trying again and again and
    again. I tell you, things got very tense when I checked my clips, spending
    excruciatingly long minutes praying I wouldn't see a damn glitch. Man, the
    frustration when I finally saw one after several minutes. In any case, while
    I could get the job done in the end (unlike my current situation), it did
    mean that I couldn't trust my computer, so like I suggested earlier I had to
    check each and every clip in real time to make sure it was glitch free. What
    a pain.
    Well, a few people have been suggesting that the fact that I lack a sound
    card, using the motherboard's audio capabilities instead, may be part of the
    problem. I don't have a card now and my old computer didn't either, and
    besides Premiere there are several other little problems I've been having
    other the last 3 years or so that seemed to be licked to audio in some way,
    without me knowing exactly what was causing them. So getting a dedicated
    sound card may help. If it doesn't fix my Premiere problem it might still
    help in other ways.

    Thank you for your post!
