Rendering Preview leads to black video

Hi. I'm making a Live Concert DVD, and in cutting the footage I've run into a problem. My timeline is complete, and I've finished editing it. However, the second half of the show is unrendered (preview wise, it plays a preview but it has the green bar above the timeline still). When I render out that preview footage, the video disappears and all I see is black. The audio for that section still plays, but the video doesn't. I tried to get around this by exporting to a Quicktime file for DVDSP without doing the preview render, but there it outputs it as simply black with the actual audio as well. Has anyone else had this problem or have any suggestions? Thanks!

Reinstalled QTPRO / MPg2 filter. Can open my own VOB files!!!! These are movies I made in Video_VOB form. If /when I try to export these movies as a QT Movie and choose settings - QTPro crashes.

Premiere CS4 sequence/esting rendering leads to black spaces

Help! When I drop a sequence
into another sequence and render it out, sometimes black video will appear for a few seconds. The same thing happens on some clips when I nest 2 or 3 layers together in a sequence (even though it plays back fine if i go to that sequence). The videos all seem to play back fine in their original sequences. And this will happen in exactly the same place if I try to rerender that sequence in another sequence. And I'm talking about anything really complex here.

Thanks, that is a good option. I was able to find and remove two clips on the raw footage timeline that seemed to be causing rendering problems. I have not had any crashes since. If I do, I will use your advice.

Video Preview Screen Is Black But Still hear the sound

I was having problems viewing previews for movies and videos. Itunes support kept having me re-install just Quicktime but it never solved the problemn so I started digging around the prefernces for Quicktime. Here's what I did:
1. Open Quicktime, click on edit and pick Quicktime preferences.
2. Choose the advanced mode and click on all the Direct X options.
3. Hit apply.
4. Close Quicktime and open your itunes.
This should fix it. Hope this helps anyone else who has this problem.

Thanks for this tip! It solved my black music videos preview and overall poor Quicktime performance

Pre 9: black video, only sound.

I used to use premiere many years ago, but this newest version is totally different from what i've used in the past, so bear with me.
here's my problem: When editing my video, I can cut and rearange clips pretty easily, everything seems to be working fine, however when i go to render the final product, or apply any sort of effects (i'm trying to keep my edits simple for now, but in the future i'm going to need to be able to green screen, color correct, and other effects) I end up with a black video and only audio. this loss is permanetly part of the project, even if i re-load another save. (edit: never mind this bit, i can re-load just fine) it seems to only occur when i have a lot of clips, since if i just apply filters or render raw footage it seems to work just fine.
my machine, though certainly not top of the line is pretty respectable, Its only a few months old and will play any game with full graphics settings (i'm a gamer so this is my best point of reference, I know video editing can be more taxing) specs:
AMD phenom X4 3.4 ghz
4 gigs of ram
NVIDIA GeForce GTS 450 (with latest drivers, i updated them about 20 minutes ago)
windows 7 64 bit
I don't really know much about video files (there's so many variations!) so here is the properties window:
type of file: Movie Clip (.MPG)
I've tried a few different presets with this file and all of them get the same results. I tried standard dv 48hz, whatever the default was, and the standard 48hz under the hard drive (since it mentioned sony cameras and that's the brand i'm using)
I'm really at a loss of what to do, but i would be happy to provide any further info if you think you could help me.

Thanks for the help guys. I got the project set up correctly, and all seems to be in order. I also think there may have been issues with converting when rendering the final product, but I could be wrong on that.
also thanks for the tip on mpeg and GOP, i have noticed in the past that editing files from this camera can lead to the sound and video getting out of sync. oh and to answer your question, it's just a simple sony point-and-shoot that i was editing for this particular footage, though I also have a flip (and I did see that there are settings for my flip)

Quicktime 7.5 - Black Video and no Audio - Using Windows Vista

Hello,
I tried asking this, but I don't think I was clear enough.
Current Computer - Dell Inspiron, Quad Core, 4gig Ram, < 1yr old.
Running OS - Vista Home
Up until recently Quicktime worked fine, then all of the sudden the video is gone.
The audio is still there however.
What I have done to try to resolve -
1) Reviewed previous topics and tried the following -
a) update Preferences to Safe Mode (That made a white stripe in the black screen)
b) Update preferences to remove Direct 3D video acceleration, nothing changed
2) Reinstall Quicktime 7.5 - No change, still shows BLACK video and will play audio
3) Reinstall Itunes with Quicktime - No change still shows BLACK video and will play audio
Thank you for any help you can provide!

I have found a temporary workaround for this. I can open the indeo 5.1 formatted avi's in another program (either fade to black or virtualdub) and change/convert to another indeo codec called IYUV (as opposed to IV50) and while it renders a much larger avi file, those DO open in Quicktime, and when I export to convert this larger avi into a MOV file, it is about the same file size in the end product as the ones I render from the same 5.1 avi on the other computer. Knowing I can do this as needed saves me having to re-render all 400 or so of my avi's to another codec or lose them.
I STILL think there is a fix out there that is related to somehow telling the registry to recognize the ir50_32.qtx codec the same as I finally did to get Windows MP to play these files, but I haven't figured out how to do that yet.
Progress is supposed to make these files SMALLER with BETTER quality, but all I see so far with these "new improved" codecs is bigger files and no better (or even worse) image/sound quality. I'll change to more "modern" codecs when they show me one that is an actual improvement over the old one based on this criteria. And AVI remains the ONLY file format that can be extensively modified and edited artistically (zoom, crop, add watermarks and color filters and special effects). Apple is shooting themselves in the foot if they make us unable to open our AVIs in the pro version so we can continue to use QT Players on our web pages. I LIKE the mov finished product for both file size and quality, and I am happy to drive new customers to them as long as they let me convert my files in QT Pro. When I can't any longer, I'll convert every single website on all my websites player to Flash.

Adobe Flash with R9 290 Hardware Acceleration Black Videos

I am not sure what causes this bug. I can restart the computer and it fixes the issue but randomly after a while it goes back to black. I can disable hardware acceleration and sometimes that works and sometimes it doesn't. There are 2 other people I know that had this issue. This happens to me both in Firefox and Chrome.
http://www.tomshardware.com/answers/id-2179088/290-black-screen-issue-possibly-due-adobe-f lash.html#14303459
I would report it to the bug site but it seems to be broken.

R9 290 Black Video Bug - Imgur

With hardware acceleration, we basically just hand everything off to the video card driver. It's pretty much an on/off proposition. My recommendation would be to install the latest AMD drivers that match that chipset to see if there are bugfixes that the OEM hasn't picked up. Ongoing driver updates on these OEM cards typically aren't as good as what you'd get from an AMD-branded card, but the AMD drivers will typically work (but are unsupported) for the cards made by third-party integrators. Just set a system restore point or keep a copy of the OEM drivers handy in the odd case you need to roll back.
If you're experiencing this with hardware acceleration disabled, make sure that you're looking at Flash video. YouTube serves a lot of HTML5 video these days. If you right click on it and it says About HTML5, disabling hardware acceleration in Flash isn't going to help you.
Anyway, if you're for sure looking at Flash videos that aren't rendering and hardware acceleration is disabled, please send me an exact link to the video that reproduces it.
In addition, detailed information about your OS and the browser version would be helpful in attempting to reproduce it on our end.
Thanks!

Locked a Black Video Layer and Premiere Pro CS5 Hangs Up

Ran into a problem whereby I have on Video Layer 1 a layer of Black Video about 30 minutes long.
I have 2-4 additional video layers above and about 9 audio layers.
When I locked Layer 1 which has nothing more than a premiere pro generated Black Video layer, Premiere Pro CS5 completely froze up, became unresponsiveand not even able to move the CTI, particularly when I tried to zoom in on the layer. However when I locked any of the other video layers, not a problem. Hardly ever lock layers so didn't notice it before.
Filed a bug report but was curious if anyone ran into this problem.

Nope, me neither. Caught me by surprise. Tks.

Use of Black Video to Fill Timeline Gaps???

Hello,
I have read articles in the past on using black video to fill any gaps between clips in the timeline. Is this a nessecary proceedure? I have rendered plenty of videos without doing this, and had no problems. Premeire will simply render black frames wherever there is not a clip. Does anyone have any pointers on this?
Thanks,
Clayton Nolen

It depends on your specific workflow. There can be advantages to moving clips around when there are black videos keeping everything from inadvertently sliding around and getting out of whack.
But there is no reason to have black video that in any way makes a difference to the output.

Black video after exporting sequence in FCP7 - help please!

hello,
So i'm not doing anything new - i've edited my clips as usual, settings are all as usual, but after i export the finished sequence and try to play it back, all i get is a black screen, with audio, for the entire duration of the sequence.
in the canvas it plays back fine, theres nothing to render, i've tried both with H.264 and Apple prores 422 HQ and nothing, i have tried to export as QT and also using QT conversion, checked the video settings there, all good, the video is rendered, also i checked the video processing in settings, used both render in RGB and render in 8 bit YUV, but no luck.
and i dont think it has to do with in and out points because the black video I get IS the duration of the audio, and the whole sequence for the matter.
The only thing I am wondering about is that I added some png files to make "gifs" over the video - I exported this same video BEFORE adding the pngs and everything was fine, but it is after adding these still images that the whole video goes black after exporting. But I have done similar projects before, with the same type of files, and I have never gotten this problem.
note; there are only a few of these still images scattered over the sequence, the majority of the video doesnt have these pngs over, but it is the whole of the video that goes black after exporting.
Can someone help me please, i dont know what else to give a go at and i cant find answers to my problem online!
many thanks.

Could be your sequence is corrupt. Create a new sequence with the same settings and copy everything from the old sequence to the new sequence.
If you need help with this post back.

Color Bars play instead of Black Video

I created black video from FILE>NEW>Black Video
I placed it on the time line and when I play it I get color bars
Any Ideas
Thanks
Dennis

Dennis,
The only thing even remotely like this is some problems that QT has with "synthetic" Video, like Black Video and Transparent Video, but nothing like what you are getting.
So I imported some old black video that I had output before I had up graded to CS4 that was .avi video. I dropped it on the time line and I got Black Video.
This was basically the solution to the QT issues - Export the "synthetic Video" as the proper format/CODEC for the Project and all was good - still, we're talking Rendering/Transcoding issues, and not Color Bars there. In those cases, it was the lack of synthetic Video, and was not version-specific. Once this material was Exported to Video, it worked fine. While this could get your Project finished, there has got to be some reason for what you're seeing. You should be able to Export from a Sequence, the Black Video to match your Project Presets and then Import that .AVI, etc., into the Project, to replace the synthetic Video. I do not think that you'll have any problem doing this from a Sequence in CS4, or you could use the old material.
I'm thinking, but can't come up with any new tests to make you run. Thanks for trying the stuff I've thrown at you, and sorry that we're not any closer to the cause, than when you posted.
Good luck,
Hunt

Preview screen is black...

whenever i go to my list of video effects on imovie hd 6 i click the effect once and the preview screen is black it says its playing but its just black. everything else is fine, like i can apply the effects and everything but i just cant preview them
please help
thanks.

Is your machine Quartz Extreme capable? iMovie will usually let you know if it is, or not. If not, certain effects, such as transition and video effects previews, Ken Burns effect, etc. won't work correctly.

Adobe Media Encoder CC outputs black video

I've been having problems with AME for quite some time, such that I don't even use it except for very short videos. If I export video in AME, the first half is good, but the second half is black video only. If I export directly from Premiere Pro, all is well every time. It's most frustrating to be paying for a product monthly that does not work, so please overlook my frustration. Has anyone successfully gotten a discount from Adobe for the failure of software to work as advertised?
Here's another issue I have: there is no way to file a bug for AME as it is not available in the drop down list on Adobe's support site. (How is that even possible?) I would have reported a bug long ago if this was available.
Has anyone seen this? I've tried many different things the last few weeks but have given up using AME altogether. This week I have a little time to troubleshoot.

Ask in the AME/ Premiere forum and by all means provide some solid technical info - system specs, sequence settings, render settings, footage used. Nobody can help you without that.

Black video thumbnails in iPhoto (Mavericks)

Hello everyone.
I have Mavericks on a late 2012 Macbook Pro running iPhoto 9.5.1.
I recently noticed that rough a third of my videos were displaying thumbnails that are just black. I freaked for a second, thinking the movie files were gone or something but thankfull the video files are still there and play just fine.
Still it would be nice to see that the video thumbnail images are rather than just black rectangles, right?
I tried all the different iPhoto rebuilding options (which takes a heckuva long time! ... then purchased iPhoto Library Manager and attempted some rebuild options using that with no luck.
Wondering if anyone has had this issue too and/or solved it?
Cheers!

Thanks for the quick reply!
I triple checked a handful of the video files and they aren't exhibiting black at the start.
How I checked:
- Select black video thumbnail image
- Press space bar (to "zoom" and begin playing video"
- Stop video playback at approx. five seconds in (video counter reads 00:00:05)
- Rewind "playhead" to very start of video so that the counter reads 00:00:00 and there is definately an image / content being displayed (e.g. is not black)
See attached screen shot with playhead at 00:00:00

How do I create some black video in Final Cut Pro?

I am new to fcp having moved from premiere how do I create some black video in fcp please
Thanks
Derek

Drew's right - and another way is to go to the same "film strip" (generator) to the right bottom corner of the middle box (called the Viewer) and select "Matte" > "color". It is grey by default, but in the viewer under Control you can select black. This way of making black will not lay in audio tracks, only black on the V1 - video track, (unless you have select another video track.

Lightroom suddenly stopped rendering previews

I've been using Lightroom since v1 and have been using v3 since it was released. All of a sudden tonight, while working on photos that were already in my catalog, Lightroom has stopped rendering previews and is much slower to operate.
I've optimised my catalog, I've tried purging my cache, I've rebooted etc. Nothing I've done is helping, if I zoom in in Library view I just see a blury outline that is the existing thumbnail. Some of my other images don't even have thumbnails anymore. If I go to Develop view it behaves normally, it's just Library view that seems broken.

I'd purged the CameraRaw cache, but after no success I ended up deleting my entire "Lightroom 3 Catalog Previews.lrdata" directory (which freed up 30GB of space and took over 10 minutes at the command line).
Fingers crossed it seems to have resolved my issue... certainly on relaunching Lightroom it's now recreated this folder, hammered my CPU and successfully created new thumbnails for the folder I was viewing in Lightroom. It's a little concerning just how much it hammered my CPU (100% for about 5 minutes, still sitting at 75% now after nearly 10 minutes) when I was only looking at a folder with 23 images in it... it was also hammering my Lightroom/System disk for the first 5 minutes, but not the disk with my photos on it.
Oh well, will see if it happens again and I might start to manually delete the previews folder semi-regularly.
