Quote: G'day Steve -

No - I don't think it's anything to do with Win7 updates or IE. From what Kevin posted in the other thread, it appears to be a YouTube problem with "certain" WMV uploads... and not just with PD9! Users of other NLEs are having the same problem.

I just did another quick test to check whether YT may have corrected the issue - but NO... http://youtu.be/RI2AQY2CF4A
Here's the same clip produced in PD11.

I still find it strange that the issue only happens with PD9 - not PD10 or 11. When you look at the MediaInfo reports from both produced files they're identical (except the bitrate which I forgot to change).

I guess - for now - all you can do is upload in a different format.

Cheers - Tony



Thanks Tony. I produced in MP4 and uploaded and it worked. Not too sure about the quality though... definitely not the HD that it appears as on my computer.

Cheers,
Steve
Quote: Hi Arthur -

If you've uploaded a WMV file, it's a YouTube issue with WMV files out of PD9 (and othe NLEs apparently)

http://forum.cyberlink.com/forum/posts/list/27671.page

If you upload in a different format (e.g. MPEG-4) through your channel, you'll find it's OK.

If that's not the issue, you'll need to give more information about the source video & the production selections.

I seem to be in almost exactly the same boat as tanstaafl49, except that all my downloads have been in wmv. Previous downloads to youtube all worked fine. Now, all of a sudden, all my downloads are turning out flattened, stretched horizontally. I wonder if any of this is related to my recent Windows7 Internet Explorer update a couple of days ago. Before I got that update, I briefly had trouble getting onto youtube because google was pushing their Chrome browser, and for a day or two, it seemed that the Chrome browser had become a prerequisite for further youtube access. The latest W7 update "fixed" that... but at what price?

Again, it looks fine when I play the wmv file back on my computer.
Robert, if you were to start out all over again with a new camera, would you stick with the GoPro, or would you recommend something different? What about the Drift Stealth Action Camera that some hangies have been using?
Tony: "why not produce as AVC 1440x1080? The output will be 4:3 with no distortion... & there'll be less re-rendering."

Works very well. No corrective stretch, nothing. Just one-for-one perfect replication. No change in flow quality (jumpiness), either. Can't tell the difference in any way, shape or form.

Good call about updating my GPU drivers/software. I haven't done that for a loooooong time, so maybe that'll get rid of the green, empty screen, in the original scenario I described, once I get around to it.

You were both right. It was a GoPro.

Thanks James, for the lowdown. Quality degradation after processing was a priority concern for me in deciding on the editing program to buy, but I balanced that against value for money. Fortunately, in my situation described above, replication has turned out to be good, in the end. But there are quirky issues I've noticed, touched on briefly, that raise questions about the robustness of PD for all circumstances. Still, PD comes at a good price and is fun to use. And just to clarify loss, James... I'm assuming that you've factored in all variables, like flow, robustness, etc. As you know, picture quality is but one dimension of the whole package. A pretty frame don't mean jack if the rest of the clip is unstable or jerky. How does MAGIX/Sony Vegas compare on the other performance variables?

Thanks everyone, problem solved.
But that's an aspect ratio of 3:2, which falls into neither mainstream camp. And must my original, glorious high-definition videos have to compromise with a drop in quality?

You ask, "What will make my video?" A friend of mine attached his camera to my glider, and I don't know its specs. All I know is that the original source vid looks terrific and it would be a pity to compromise on that. I just want to get past first base and establish, as close to possible, the same quality as the source, and then decide later on the media that it should be viewed on.

cheers
Following on from the recent produced video issues thread, as suggested by senior contributors... thanks ynotfish for your analysis, but it's true, I do get the green screen problem when doing the same routine. But I've found a fix for that problem, at least for now... The more urgent problem is distortion in the produced vid.

My produced video in fullscreen mode does not match one-for-one the source video in fullscreen mode. For example, when I measure the length of an object on the screen in the produced vid, its length is very different in the source vid. An object like my arm, say, seems to be 75% shorter in the source vid than it is in the produced vid. The produced vid seems to be mulitiplying the fish-eye effect of the source video, but I can't be sure what exactly is taking place, because I cannot view them side-by-side in fullscreen mode.

I'm suspecting that it might have something to do with the aspect ratio. I want an aspect ratio 4:3 with resolution of 1280x960, but that option is not available in PD (or at least, I cannot find it). So I've tested my productions with two available resolutions, being 1920x1080 and 1280x720. But the distortion problem is replicated pretty much identically in fullscreen mode, from what I can make out.

When I'm not in fullscreen mode and when I line up the videos with the same horizontal resolution (1280) they line up vertically ok, but the taller vid is in 4:3 and the other is in 16:9, so clearly there is something that needs to be cleared up here.

Here's the specs of my source file:
Type: H.264 AVC (but I output it as MPEG4 high definition, because I don't have a blue-ray player)
Bitrate: 12.32 Mbps
Resolution: 1280x960
Frame rate: 29.97 fps
Aspect Ratio: 4:3
Profile: Main profile

Thanks in anticipation
In the event that this might assist Laura or other newbies, here is the solution to my original question...

It seems that PD does not like to reproduce source files that it has already produced individually, even though they are still MPEG4s. That is, produce your project once only. Don't produce file by file and then produce the whole again.

I still have the problem of distortion and reduced quality though, and if anyone has suggestions, would be appreciated. Thanks.
I seem to have exactly the same problem as Laura.

I've taken on board one of the answers suggesting that it might be the player. But in my case, I've had 4 video clips about 500MB each that played back fine individually, but when integrated into the production as a single movie, nothing but an empty green screen for the most part, with a few seconds of footage before going green. So I'm wondering if it is a question of file size (more than 2GB in the final production).

The format that I produced it in was high-definition MPEG-4. This was also the format of my original source files.

Also, I'm a complete newbie at this, so if the answer seems obvious to someone, please be gentle with me

PS... while I'm here... I'm a little disappointed with the post-production change in quality on the smaller 500MB files. Is there a way of minimizing the distortion/quality to match the output specs with the input specs? I'm thinking of getting boilsoft file-splitter to circumvent this, given that their file-splitter does not reprocess the file in the splitting process (the output file format matches exactly the input format).
