VideoStudio :: Clips Are Jerky Within Project
Jun 4, 2012
I just created a project with many different clips. Some of them play perfectly while others are jerky in playback. The original videos were imported to Correl from video files downloaded from the internet. Some of them are MPEG and others are AVI. It seems that the MPEG files play fine while the AVI files are slow. Not sure why this is since I created another very similar project and the AVI files in that project played back fine.

I am importing some .avi files and burning to a disc. Most of the .avi clips are fine on the DVD, but two that have panning sequences are very jerky. I checked the source .avi files and they pan smoothly.
I've explored changing the Speed to Quality slider and also the Frame Type (Upper/Lower field first) setting to no avail.
AVI Clip Properties:
File Format: Microsoft AVI files
File Size: 13,513 KB
Frame rate: 23.976 frames/sec

Data rate: 215.01 kbps

I'm wondering if it is normal for my clips to have jerky preview. I am editing 1080p MOV clips and I've made sure that Smart Proxy is enabled and that the files do exist. Smart Proxy settings are default to activate with any clip that is larger than 720X480. After I've dragged a clip onto the timeline I get jerky preview if I select "clip" and then click play. But if I select "project" it plays smoothly. Scrubbing is also smooth. My question is why are my clips so jerky? It seems that "clip" preview is automatically using the original video file and not the proxy. I'm on a slow computer, but that's not the issue because everything except the individual clips plays smoothly. And yes, the Smart Proxy icon is on my clips and it's had plenty of time to complete the proxy creation. I've even completely removed VS with Revo Uninstaller and reinstalled it. No change.

Have just started working on VS and discovered a strange issue. I can put a piece of video in the clip window to mark in/out points and it plays fine. When I drag it to the timeline and play as a clip, there is no audio!

Problem I was having was using clips of various sizes and properties in the same project. Original entry follows below.
I have a new system (see my profile) that I think should work with Pro X4 just great.
However, I had some AVI videos I tried to edit. I could not get frame resolution in the time line, as I remembered getting with older Corel products editing MPEG files.
Nevertheless, I was able to edit AVI and get good results as long as the AVI files did not have sound. When I tried to edit AVI with sound, preview was unusable. The transitions got lost during the preview, and the sound dropped out around cuts and splices and transitions.
Needless to say, editing did not go well without a decent preview. Are these artifacts of trying to edit AVI files, or is there something else amiss? Should I be capturing in MPEG or some format other than AVI?
The following settings seemed to get the best preview results, but I still had sound drop outs around cuts, splices, and transitions (which are splices). I expected the sound to x-fade around transitions.
NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps
Upper Field First
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 6000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 3/2(L,C,R,SL,SR)
I set the project to MPEG, even though the source was AVI, because it seemed to improve the preview response time a bit, but not enough to make a real difference.

I'm trying to integrate 16:9 HD video clips into a 4:3 project (or vica versa). Obviously it will take cropping the edges but how? VS does not appear to be up to the task that I can figure. Maybe a third party utility?

Basically, I want to use part/pieces of several project files already created, i.e. to combine the chosen sections into one new project file. Have looked in the Manual and cannot locate the answer! I am now using Prox5.

I'm working on a project that pulls together many short clips from many much longer video files e.g. there might be less than a minute pulled from a 60 minute file then another then another etc. I found that my computer (which is reasonably beefy) was struggling to cope with the workload so I split the project into separate project files i.e. Part 1, Part 2 and Part 3. My thinking was that once I had done all the editing I could cut and paste all the clips into a single new project file before rendering the entire thing. But I can't work out how to do it! Sure, I can copy and past individual clips or even a sequence of clips but on pasting they lose all the editing I've done! I just end up with a uniform bunch of unedited clips!
I guess the alternative is to render each project file (1, 2 and 3) separately then pull the rendered videos together into Project 4. I can then render Project 4 to give me my final 'movie'. But surely that means as I've rendered everything twice I'm suffering a quality loss?
So the question is: is there any way of copying edited video clips from one project file into another project file AND retaining all the edits?

I have previously created a project using avi files and successfully burnt a dvd. Now when I reload the project all the AVI clips on the timeline are "unreadable" (black and white horizontal bands) yet they have not been moved from their original folder and all clips are visible on under "video" on the "edit" page. I have even tried relinking but to no avail. All the clips still play perfectly on Media player.

After realizing the Mercalli runs better on single clips, is there a way of editing a clip within a project and saving (after "creating" this clip only) and then reinserting into the project?

Not had this before, just put a couple of minutes clip into the timeline ready to edit and when I play through it, the video is jerky/jittery on playback. If I click on it in the library and play it without pulling it in to the timeline, it is fine, and if I click on the video without opening the programme, it also plays fine ? If you watch the timeline scrubber as the video jerks, you can see a trail of little white shadows that the scubber leaves behind as it stutters ? I have tried with other clips and it does exactly the same ! The clip is AVCHD clip, and.... I have let it create a smart proxy file before playing it.

I am using a trial version of Videostudio Pro X3 and am experiencing some difficulty producing good quality DVD's & video files (via share->Create Video File).
My original video has been captured from an 8mm camcorder and is good quality. The file type is MPEG-2 TS Video & is 2.2GB.
If I import it into the timeline, select Share->Create Video File->Custom and set the video data rate to 8000kps
my resulting mpg file has overall good quality but there are some very jerky movements and pixelation.
These are not present in the original mpeg-2 file. I get a similarly poor result if I select Share->Create Disc which starts up DVD Factory and burn a disc
However, if I have nothing in my timeline and select Share->Create Disc which starts up DVD Factory, add media, selecting my MPEG-2 TS Video file and then burn a disc. The resulting disc is excellent quality with no jerky movements or pixelation.
However, this isn't much use to me because I want to edit my video but seems to prove that something strange is happening in VideoStudio Pro X3 or my use of it.

Using a Canon Powershot G12 camera and it records 1280x720 px .mov, H.264, 23.976 fps.
Doesn't matter how my project properties are in Videostudio Pro X3. Think I tried almost everything. As soon as I create a video through VS Pro X3 (all update patches installed) the result is a jerky video. Using the recommended (by Corel) version of Quicktime, as the most recent Quicktime version causes VS to crash. Tried this on 3 different computers with the same result.
Project settings:
TV standard: 24 fps
Frame rate 23.976 fps
Frame Type: Frame based
Frame size: 1280x720 px
Compression: Doesn't matter (same result anyway)
Share:
Create Video File:
- Same as project = Jerky video
- Upload to YouTube (MPEG-4 HD 16:9) = Jerky video
- Xvid or any other format = Jerky video
Here is the file on YouTube as it should look (original .mov file from the camera directly uploaded to YouTube): [URL]
Here is the file on YouTube after created with Videostudio Pro X3: [URL]

basically my 24fps footage isn't rendering smoothly ON X5 Ultimate.
[URL]
What i've done is put the same clip together twice, as strangely the first clip is smooth, then subsequent clips are all jerky. This has been going on for some time, so switched to 25fps. 25fps from my Canon 5D MKII wasn't as good as 24fps, so switched back and decided to try and sort this out.
I have been through multiple settings, deleted all older versions of Corel, removed then re-installed X5, made sure all patches and updates were installed - made no difference.

I have a number of video files captured at 1080X720 full frame resolution at 29.97 frames/second, shown on my PC as .MOV files.
When watching the original files either on my PC or TV, movement is fluid and smooth.
When watching a finished video created via VideoStudio Pro X4 using the aforementioned files, movement is jerky, and is particularly noticeable when watching a panned scene. The effect is so bad that it makes viewing on a large screen impossible as the picture movement jerks/judders about. I have looked at the project preferences, and notice under Project Option>General tab, the only available frame sizes are the standard ones which only go up to 720X576. The radio button to select a user defined frame size is greyed out and cannot be selected to input my own frame sizes. I’m therefore unable to actually input the frame size of the source video files.
Basically how do I render a finished video without jerky movement?

I've just bought a fluid head tripod and have been practising with it and getting some fairly smooth results. I've been shooting at a resolution of 1920x1080 at 30fps in MPEG4 AVC/H.264. When I watch the video in the LCD display on the video camera or plug my video camera (Sanyo Xacti FH1) into my 40 inch TV the results look smooth. But as soon as I download them onto my computer and watch them in VideoLan or QuickTime, the results are awful. The picture jerks several times a second throughout the panning shots. I have imported some of the clips into VideoStudio Pro X4, and made smart proxies of them and some but not all of them run smoothly but when I create an MP4 HD file in VS4 the results are just once again awfully jerky. My computer is only a couple of months old: AMD Athlon II X4651 Quad Core and Radion HD6700 series graphics card with 4Gb of ROM running Windows 7 Home Premium 64bit. What I can't understand is why the panning looks so smooth on the camera and on my TV (so it isn't due to the small size of the camera's LCD) but as soon as I download it to the computer it looks so awful. I'm aiming to put up some film clips of archaeological sites in Crete on YouTube and I am due to go round the island shooting video but I can't possibly put results like these on the Internet. What could be causing the difference between what my camera shows and what my computer shows?

I’ve been using very happily been using x2 for a number of years to make a lot of movies from my standard definition camera, I’ve loved the programme, and it has generally been able to do everything I wanted, and made for an enjoyable editing process. However, the camera has finally given up and I’m now going down the HD route, and the old x2 version just keeps crashing with any new clips. So I have recently downloaded the trial version of x5 (5 days of trial left), with the intention of trying it out and then purchasing it.
Unfortunately however I have found it to be jerky and jumpy when editing clips together, particularly when using the overlay tracks, the more overlays the worse it gets. This happens when I want to watch the edit, and while the sound runs ok the video just freezes on a frame then jumps ahead a few seconds and freezes etc etc. Impossible to watch and edit to really.
I am using the smart proxy to get the files to a manageable size, and I can see the separate proxy files in explorer. Smart proxy enabled. I have all the acceleration on that can go on (the ”Enable Hardware Encoder Acceleration” is greyed out so I can’t tick it). When I share/render the movie it comes out just fine, so it’s only with the editing process that is jumpy. I have really enjoyed x2, and could get good results really quickly, and I enjoyed the editing interface and process with Corel VS, but am now thinking I might need to change to a different video editing programme.

Everything is just running off the laptop’s hard drive. I’ve installed The CVS x5 Service Pack 1

I am using Elements 10 and do a lot of editing in slide show projects. I want to add video clips that are iin my catalog to my slide project. Every time I click on video clips it tells me I have to go to Premiere to activate. Is there a simpler way? I usually don't go to Premiere until I want to burn a disc..I don't need to edit the video clips.

I've built a project up with several smaller project file components. It's an easier way to create a video than editing one big project.
Opening the overall project and running it on screen is not a problem. However, when I try to create a smart package of the composite project, I get a consistent error message rejecting the process because of the existence of the component vsp's.
Is there a way to avoid the error and create a smart package from a project file that has smaller component project files?

each time I force quit Smoke with the service monitor in a project when I open the same project after it takes several time to load the clips (EDITDESK: LOADING CLIPS). Sometimes the project just didn't open and stay on the EDITDESK: LOADING CLIPS screen.
There's something I'm doing wrong or my project is totally corrupt ?

All of a sudden my Videostudio X4 will not play any clip for longer then a second or two. When you play a clip or the project it plays for 1 or 2 seconds and stops just like you hit the stop or pause button. Click play again and it does the same thing. Makes it really impossible to edit. It had been working great up until last week. I tried uninstalling and reinstalling but still have the same problem. I have excluded my anti virus from scanning the Corel folder.

So I drag and drop a bunch of video files into the timeline and want to mute them all in one easy step. It would seem that all you would need to do it right click and mute while they are still all selected from the import but the mute setting isn't active. meaning I have to mute each clip separately. That takes a LONG time.

I have ONE large 1hr AVI file captured from a DV camcorder. I have used Corel Videostudio to "split by scene", and that works fine, all clips are cpatured. BUT the shooting date for the clips are shown as the same date and time for all clips.
Where can I see the actual shooting date for each clip? I tried to use the old Win Movice maker on a WinXP machine, and here it works fine.
In corel VS I also tried to take one clip in the middle of the file and used the shared function to create an DV AVI file. This file I imported to VideoStudio - and now the date and time for this single clip is right. Unfortunately if I a convert all clips into one single file again I still have the problem.

In the past using VS10+ I noticed an issue importing sound and music clips. I did import them into my project from my music folder without any problems. The issue is when I deleted the sound and music clip from my folder it disappeared from my video project and I would have to get the clip back into my music folder and keep it in there until I burned a DVD. Is this routine for VS?

Cannot preview .MPG files.VSPro5 won’t play MPG clips.
I have only ever worked with AVI files, MOV files OR Video_TS files with few problems and have recently upgraded from CVSProX4 to X5. A family member has asked me to put all his home movies onto DVD. These are in MPG format.
I can import all the individual clips into CVSProX5 – however, the clips will only play when they are selected as the whole project. Selecting an individual clip for editing purposes results in a green screen. However I can manually move the scrubber through every frame within that clip (with an absence of sound) – but will not play that clip. I have converted some clips to .MOV format and can then play (and edit) and listen to individual clips.
I don’t particulary want to convert many hundreds of individual .MPG clips.
