With PD 20, we notice that audio & video of the same track are not synced. Video could be delayed by audio more than 5 seconds. We didn't notice such issue with PD 19 on the same computer. Video speed is not very smooth either.
Windows Task Manager shows that PD 20 takes almost all CPU bandwith when it plays a video (98% when play video vs. 1% when not paly video). Please see the attached screenshot. Not sure why PD 20 takes so much CPU bandwith, and if it's possible to improve it.
By the way, we didn't check PD 19 CPU usage when it plays video as we didn't encounter this issue.
Please see the attached video for details. We are processing an outdoor dance performance video. Since it's not very easy to replace video background even with Motiong Tracking Mask in ColorDirector, would it be possible to clean background a bit? For example, the attached video shows a couple of people in background, someones sit (still subjects) and one walks (moving subject). Would it be possible to remove them or make them fuzzy in background?
QuoteThe tool will be more likely to automatically track a moving object when the subject is clearly defined and there is little or no background. In other words, the more like a green screen, the better.
In most situations, however, I think it's going to take lots of manual editing to keep the tracking on target, and you'll then need to make sure you're using the right workflow. I'd plan on spending at least 1 hour for every minute of recorded video, maybe double that if you need to have every frame close to perfect.
I spent a few hours today playing around with this feature which I've never used to make a video before, and it's clear that when you use the automatic tracker you need to pause it as soon as you see that it's gone off track. Manually click the back arrow until you get to the first frame that's wrong and use the Brush and/or Erase tool to correct the mistakes, then try the automatic motion tracker again.
Giving it better information when it's started again should take care of the mistakes it originally made in this section, and you'll need to repeat these steps each time the auto tracker goes off track.
Here's a quick video showing these steps:
Once the main tracking is finished, you'll probably need to go though the entire video and use the forward/backward frame keys to change the mask at some or all individual frames. Doing this doesn't change the mask anywhere else and you can make as many revisions as needed.
Here's what that looks like:
Please remember that using the auto tracker or the Track one frame only button will erase all mask frames following the current frame, so don't use either one if you only want to adjust a few parts of some frames.
If you have trouble getting the auto tracker to work in any specific sections, try the Track one frame only button since that will give you perfect control over how each frame is masked.
Even though it's tedious, it will give you great results and may be faster than going back and correcting many frames if the auto tracker is having a hard time.
Here's how to use it in combination with the forward/back review & tweak method:
Thank you so much for the details, videos and your time. It helps a lot. Much appreciate!
Using Motiong Tracking Mask is indeed very time consuming. Not even mention if we use this feature to edit a vedio that has multiple fast-moving dancers. But we are still thankfull for this CD feature. Hope future CD can improve this nice feature with more precise algorithm.
Please see the attached video for details. We tried to use motion tracking mask of ColorDirector 9 (for replacing background) but it doesn't work as expect. Once create mask and start motion tracking, the mask will start missing part of dancers (leg, heads, etc.) masked originally. When this issue happens, we can certainly pause the motion tracking to adjust the mask, but the same issue happens again soon after resume motion tracking. So how can we make motion tracking mask work better and more precise?
Suppose we have two tracks. Track 1 is a video clip, and track 2 is a still photo with the color we want to match (please see attached screenshot). We plan to use (match) the photo color on one section of the video (track 1), say 40s - 50s. Can we use PD 19 Ultimate Color Match to do this job with keyframes added on video clip?
Color Match section in PD help is very simple and doesn't mention keyframes.
One option (if we cannot use keyframe) I can think of is to splie video from 40s to 50s, then match color to the whole splitted video. But if possible we'd like to keep video as a whole piece without spliting it.
Since chromakey cannot be keyframed, it cannot work correctly.
This is just by way of an illustration of what I think chromakey tries to do.
Perhaps the best way to look at it is to view chromakey as a filter not an edit. Further edits to the clip apply to the clip, not to the filtered view, hence the filter does not always work as intended.
So, assuming you don't want to change the stool clip much, just enhance the color a little etc. etc. perhaps do all that before applying the chromakey, and see if you can get the chromkey to work sufficiently well over the changes you apply.
In effect, that is what optodata suggested but his idea is more "predictable", but I think it will still suffer from the basic problem with large color changes and chromakey technology.

Thanks for your suggestion and information. Yeah, agree that chromakey is a filter not editor. That's also what we feel about it. At least the issue we reported does not affect our work. With PD 19, we can get our job done without problems. Thank you and Optodata for your dedicated support. Much appreciate.
Quote Submit a support request here, and be sure to include a link to this forum discussion so they can see everything that's happened and can download your very helpful test project.
As a workaround, produce each clip once you're happy with the chroma key settings and then do all the other edits, like Color Enhance on the new versions.
Thank you for your confirmation. A support request was entered (CS002402086).
QuoteThis may be something to report to CL tech support. You didn't mention whether changing the Hardware decoding or OpenCL settings have any effect.
As far as I'm aware, Quicktime or QT Lite are required for MOV clips and there's a chance that installing one of these codecs/support packages will resolve your issue.
Again, if you could share that specific clip here that would let other people see if they encounter the same issues or not on their systems.
I created a new and very small project that can reproduce this issue. Attached zip file contains a clip showing the steps on how to reproduce the issue. It also contains all other files including PD project file so you can easily duplicate what I did to see the issue.
Again, after change the default value of Color Enhancement from 50 to 0, this issue disapears. My bold guess is if Color Enhancement didn't have impact/changes in the areas covered by chroma keys, then this issue wouldn't happen.
By the way, OpenCL and HW decoding do not seem having contributions to this behavior. After they are un-selected, the same issue still happens.
QuoteI followed your steps of applying a chroma key to a green screen clip on track 2, then splitting the clip and adding every keyframe in the Fix/Enhance section (including Color Enhancement) a few seconds in and I don't see the issue your recording shows.
What happens if you turn off Open CL and then Hardware Decoding from Preferences | Hardware Acceleration?
You may also want to upload your green screen sax player clip as there may be an issue with it. Do you have Apple QuickTime or the QTLite codec installed?
Also, if you're not going to change every single one of the other settings, there's no need to set an initial keyframe in each one.
No, Apple QuickTime or the QTLite codec is not installed. Try to narrow down this issue. Here is what I found.
A newly-created project has the same issue
After all keyframes (including Color Enhancement) are created at 10 sec, the issue (background becomes black) is recreated. Now if I change Color Enhancement default value 50 to 0, the background is changed from black back to "transparent" (i.e. the issue is gone).
The same issue occurs even I only create Color Enhancement keyframe at 10 sec. But again, if Color Enhancement default value 50 is changed to 0, the issue is gone
QuoteBased on your other post about that keyframe afffecting the chroma key, it looks like something in your project is damaged. Try using File | Save Project As and see if the keyframe can then be deleted.
You may also want to try making a new project with just that clip and see if you're able to place and remove keyframes normally.
In the moment, you should always be able to click on Undo (or type Ctrl+Z) to remove it.
Thanks for your suggestions. We can try to start a new project but we need to keep the chroma key values we currently use. We spent some time to adjust 3 chroma keys in order to hind green background because the green background is not perfect and has shadows. Each chroma key has Color Range and Denoise, which are easy to find (see attached screenshot). But could you please let's know where we can find the keys's "main" values (they reprent where we clicked on green background)?
After adding a bunch of keyframes, chroma keys, which are used to hide green background, are malfuntion. The hiden green background becomes black. This is PD 19 Ultimate.
We add those keyframes at 10sec location without changing any property default values (Hue, Contract, etc.) because we want to lock/keep the original/default property values from 10 sec onwards. If this issue didn't happen, we would add other keyframes at 0 sec and change property values at 0 sec. The final effect would look like color is graduatly changed from 0 sec to 10 sec, and stay unchanged after 10 sec.
Just wondering why we cannot remove newly-added keyframe of Color Enhancement. Please see attached screenshot. "Add/Remove Current Keyframe" icon is greyed-out so it cannot be used to remove keyframe. Pop-up menu entry "Remove All Keyframes" cannot remove it either. We don't see this issue with keyframes of other properpies so far.
Found the cause. The chroma keys added earlier in PD, which were added before CD changes background to green, causes this issue. After I remove those chroma keys, the background is green now. Sorry for the fault alarm.
I used CD 9 (Brush Mask with motion tracking) and changed the background of a clip to green. However, the green background is changed to black after go back to PD from CD (by clicking "Back"). Please see attached screenshots.
Can someone please tell me why this happens and how to fix it? I need the green background as I need to remove it in PD.
I searched online and found an old post back 2013 (link below). It seems we couldn't open two PD at that time. Now we have a newer version PD 19. Can we do it now with newer version PD 19 Ultimate? So we can work on another project while PD is producing video (a lengthy process) for a different project.
Hi,
Maybe I misunderstand but if you play the clip in the PiP designer, it should play as in the final video??
Cheers
PowerDirector Moderator
Yes, you are right. We can play the clip in the PiP designer. Then the zoom change will be played. This is what I missed. Thank you for your remind.
What I originally expected (but it doesn't exist in PD 19 Ultimate) is a dsiplay area for final video without actually playing the clip. Please see attached screenshot zoom_2-expected.jpg. The white color rectangular I added in the screenshot is what I expected, which shows the updated view area for the final video after zoom in. If PD 19 had it, we wouldn't have to play the clip to check whether or not zoom is correct. It will make the work easier.
Not sure what I miss here. Your input would be appreciated!
After opening PiP for one clip, I can see the display area in a rectangular frame (the 1st keyframe showin in attached zoom_1.jpg), which should be what we can see in final produce video. After change Scale (by drag the edge of the pic) to zoom in, the pic is enlarged (zoom in effect. the 2nd keyframe in attached zoom_2.jpg). However the original display area (the rectangular) is not changed. If we move the slide bars, we still see the original display area but it's just enlarged. So how can we visually check the zoom in effect (i.e. what will be displayed in final produce video after zoom in)? We can save the scale (zoom in) changes, and go back to PD home page to see the zoom in effect but that's not very convinient as we have to go back to PiP again and again to fine adjust zoom in.
You didn't. I think the first method is ideal for your specific situation, while Color Match is better suited when you need to quickly match one clip to another. I wanted to make sure you (and future readers) knew about both options.
QuoteWhen keyframe attributes can't be copied, the other way to accomplish that is to place a copy of the "master" clip elsewhere on the timeline then drag and drop the clip you'd like to match from the Media Library directly onto the copy and choose Replace.
Wow, this is a nice trick. After drage a clip from Media Libray and drop it directly over the "master" clip and select Replace, the chroma keys and their attributes are transferred to the dropped clip.
The two clips we are trying to match chroma keys are actually trimmed from the same originally recorded (long) clip. Then we spent time to adjust positions for both clips. Next time we really should apply chroma keys to the original clip first before trimming them. This way, we don't have to worry about copying chroma keys from one clip to another.
Quote For specific color matching, you can also try selecting the "master" clip and an unedited additional clip then click on the Color Match button. Make sure you have the correct clip in the lefthand Reference window - use the double arrow button above the divider if you need to swap the Reference and Target clips.
You can then select reference frames in each clip and tweak the level and 3 other settings to get the best match
This procedure is very useful. What I can see is this procedure only matches color of two clips, but not copy chroma keys from one clip to another. Hope I didn't miss anything here.
Just wondering... would it be possible for PD 19 Ultimate to copy all 3 chroma keys including their Color Range and Denoise attributes from one clip to another, like what we can do for coping keyframe attributes from one clip and past them to another?
Please see attached screenshots for details. If we manually pick chroma keys and their attributes for two seperate clips, it's not easy to make two clips match 100%.
