VideoStudio :: Jaggies When Panning - Can Shutter Speed Have An Effect
Nov 1, 2013
I have recently upgraded to a HiDef video camera and at first was recording at 1080i (interlaced) and now changed to record at 1080p (progressive).
I have noticed when viewing (on my PC) some of the clips I recorded that there are 'jagggies' along the edges of objects.
I have found that this is a result of 'interlace' and possibly panning too fast. My camera displays a warning "camera is panning too fast" if in fact I do pan too fast but this was not the case as when recording with panning I usually pan so slowly that I often have to increase playback speed during editing AND also the clips I viewed were on people walking in the same direct at the camera, hardly panning too fast. With that said I am thinking (and hoping) that it was a result of using 1080i (interlaced).
This begs the question - Can shutter speed have an effect. The reason for the question is that I have noticed that my new camera (seems to) automatically sets the shutter speed faster and leave the aperture wide when there is a lot of light (I can see that by changing to MANUAL mode and noting the aperture and shutter speed.
If this is the case then should try using a NEUTRAL DENSITY filter to force the camera to use a slower shutter speed? I used to have to do this with my old MiniDV camera to prevent overexposure in brightly lit scenes (the shutter speed never seemed to change without me manually doing so).
I'm near completion of a year long video project. I inserted several HD video clips into my VS X4 time line which includes many other HD/SD and .jpg clips along with transitions, music, etc. For effect, I used the tool in VS to speed up two or three of these clips by about 300%. Without the effect, the scene doesn't work so I'd like to keep it this way.
I noticed that when playing the clip in the time line after the effect is added, it plays very jumpy and jerky. Without the effect it plays fine as do all the other clips in my project. I am guessing the effect puts a strain on the system but mostly, my system is fine. However, the hard drive may be the culprit and not able to get the data fast enough to provide a smooth video. Is that possible? My cpu (core 2 quad Q6600 clocked to 3.0 g), new video card, memory, and monitor (HD certified) are all new and well within spec.
My question: Do you think the stuttering video will also be present in the final burn of a Blu-Ray? Or is this just a function of the preview window?
I have a technical question I wonder if anyone on here can answer. I am far from a Photoshop newbie having been using it from version three, but rarely get the chance these day to fathom all the new widgets on new versions.
For many years I have always hoped that Adobe would include a filter for a speed blur. I know it does a motion blur, but what I want is a blur that show the direction of the apparently moving object. I am working on a project where I have animated a chilli on the companies web site where it flies around. I want to give the impression of movement with the blur coming from the tail of the chilli for a leaflet.
Here's the image I am working with, though it looks a bit crap here as it's cmyk.
I captured in HD, edited in Video Studio X3 then output to MPEG using same settings as video files. I then gave up trying to burn using Movie Factory Pro 7se as it kept crashing during render so I used DVD Flick. the resulting DVD seems fine apart from when the camera pans and the video appears to be a little blurry. Any stills or slow panning are perfect.
Dropping the bit rate from 9000kbps to 8000kbps but that just made the video look awful.
Basically, I have a Sanyo HD camera which I've used to capture quite a bit of holiday footage. I've edited some together but when I output the project to either mp4 or mts the picture is choppy when panning.
The camera was set to 1080p @ 30fps (there's no option of 25fps even though the camera was bought here in the UK) which I have matched by choosing the "Custom" option when creating the movie. I've matched the bitrate (16789bps on the source) but this ends up being 15540bps on the output file. (??) According to the properties on the source file it's 29.97fps which I have also matched in the Custom settings option.
I understand I should expect dropped frames if I was trying to output the file as PAL compliant, but I've got VS set to NTSC so I don't think this is an issue.
The source file is mp4 and looks fine when viewing the panning scenes.

A friend gave me an SD card of her wedding to tidy up and put onto a DVD. The format is MPG-4. The clips play fine but as soon as I put it all onto onto the time-line I get the odd jump on panning of the camera, which are not there on the clips. I know this can relate to the project settings and I have played around with these, adjusting the bit rate up and down.
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 thought I would just check with the experts before I go down a road that may be a dead end.
What I am trying to do can best be described if you happen to have watched some of the Harry Potter movies, where they walk down a staircase that has all the historical paintings on the wall. Unlike standard paintings, these ones take on a life of their own and have movement inside the frame.
I would love to do something similar, albeit in a simpler fashion, by having a large static image on the main track, containing several picture frames, and then pan and zoom around this static image looking at all the moving images (videos) in the picture frames.
One thought I had was to create a very large images (4000 X 3000) containing all the picture frames. Then, in the overlay tracks I would place all the videos that would represent the moving paintings. The videos would be lined up with the picture frames using the picture-in-picture effect, and then I would pan-and-zoom around the static image viewing all the videos as they played simultaneously in the overlay tracks.
I fear there are several problems with this strategy, the central issue being that when I pan-and-zoom the main track, the overlay tracks wont pan-and-zoom with it.... Perhaps I could move the videos around the screen in sync with the pan-and-zoom, but that seems pretty difficult.
Is what I am trying to do even practical in VS Pro X4?
I am very familiar with the editing software I have (Video Studio Pro X3). I was wondering if there was a way to make your title stationary, while the camera is in a panning motion for instance.
For example, I want to pan right to left and have my title sitting on a tree branch the whole time stationary as if it were "in the scene" I searched forever to find an example but came up with nothing.
I do understand if this editing software just isn't capable just want to know if it is possible.
When I try to combine 2 videos to play over each other (i.e. one full screen one anchored in a corner) the overlay track plays at an accelerated rate with no sound, whereas the main video will play as normal. However if I switch them around the same problem arises, the overlay video plays fine the main accelerated with no sound.
If I play them separately they will both play fine. The video I am trying to anchor was recorded with a webcam and therefore may be the problem. If I need to give more details w/ specs etc.
How to setup the burning speed for DVD using the Videostudio x4??? My setup menu for adjusting the speed recording wont highlight.. I've try to reinstall the software many times, but i wont get it done.
Problems in selecting the DVD recording speed in VideoStudio pro X4? I prefer to use a fairly low rate, but the selection is greyed out in my Create DVD window and it seems to be set permanently on maximum. I've tried a program re-install but it hasn't worked at all.
Since quite some time I have been succesfully uploading FullHD (AVCHD 1920x1080 50i) movies on YT. Some weeks ago I got a strange playback problem with my last uploads: video's are played in (very smooth!) slow motion mode at some resolution settings. The same Divx video's on the contrary always playback OK In order to illustrate the YT playback speed problems I uploaded two times the same 10sec video. The first video has been rendered as a fullHD AVCHD video in VSX4 (never got problems in the past with similar video’s), the second is a fullHD DviX version of that same video (from another converter). The lower resolution settings in the AVCHD video slow down while the 720 and 1080 settings run OK [URL]
I wish to use the Speed TimeLapse effect (actually slow motion) I have a clip that last approx 8 min I would like to "slow motion" only a portion of the clip approx 20 sec. Is it possible to apply the effect without having to cut/trim the original clip. The clip properties are as follows;
ntsc/hdmv H.264 Video Upper Field First ;1920/1080 16:9 ;24bits;29.97 fps Audio 5.1 Dolby Digital
I'm trying to get my audio synched up. Someone once told me that the best place for the camera is often the worst place for the microphone. And in my case it's true.
So- I am trying to use audio from a different source and the speeds are very slightly different. I have the beginnings synched perfectly. Toward the end I stomp my foot- it sounds like a door slam and is something I'm trying to use to synch the two because it's a loud sound short in time.
Doing it visually doesn't work because VideoStudio (version 2) doesn't preview the video properly. So I had the idea- don't mute the source audio so I have both playing. Then render an audio-only file and listen to hear how far apart the two stomps sound, and adjust the audio track's speed.
I've shortened it by 2 frames and 10 frames but it still sounds exactly the same. Is there a bug in the audio-shortening feature or am I missing something? I tried using Audacity to shorten the audio but that didn't work well either, because it rounds off, and 2/30th of a second over 30 min is a tiny fraction.
I've got a lot of crossfade transitions in a project and want them to be 2 seconds. Altering the default 1 second for every one is a lengthy pain - is it possible to change the default and if so how>?
I have a video shot from inside a vehicle driving down a rural French road. I would like to increase the speed to 110% to 115% as the video progresses to match the music I will overlay it with.
I know how to increase the playback speed, but I can't seem to find if it's possible to do it gradually. Everything I try increases the speed all a once. Is this possible (gradually increase speed) with the Playback Speed settings, or do I need to make two clips of the same segment, 1 at regular speed and 1 at the final speed, and use a long transition between them?
I use X5 Pro. I have some projects with lots of video clips. When I load a project, the project itself loads fairly quickly (as indicated with the green progress bar), but the Icons in the Project area then begin loading ONLY for the page being displayed. This applies for both the storyboard and timeline view. This is very frustrating, especially on the storyboard view, because every time I scroll a page I have to wait for the icons to load. With a lot of pages, it takes a very long time to get everything loaded.
Is there a way to either speed up the loading process or have it load in the background so that I can leave the computer and come back later to find the icons all loaded, rather than having to sit there and scroll through one page at a time waiting for each page to load until all pages are loaded?
I have used many different video editing packages and really like videostudio. The high quality output and many features make it a solid product.
However, I am confused why there is no way to change the speed of an audio or video clip in smaller than 1% increments. 1% is a very large increment, even when dealing with a 3 minute clip. An exact sync is near-impossible. .1% would be a great deal better.
I see in the 'change speed' dialog that you can also choose the clip duration, down to 10ths of seconds. But when I do this it seems to 'snap' to the nearest percent.
Is there no way to change the speed in smaller increments than 1% or am I missing something?
I have a video recording of an event with not so good audio, but also a separate high quality audio recording. The problem is that the audio recordign speed is not the perfect match to the video recording, and when I put them in overlap, audio runs about 2-3 seconds quicker than the video by the end; seems real bad.
the obvious solution is to adjust the speed of the audio to match the length of the video; sounds easy.
One small problem is that the audio recording and the video recording were not perfectly synced, so the audio has some superfluous part at the end, so all in all the situation is as below:
Video track length: 1:57:16
Audio track length 2:14:20 with a lot of wasted part at the end
Current length of the Desirable Audio track: 1:55:15; this is the part which should in fact finish at 1:57:16 to match the video.
Below is what I did:
1- Clipped the audio at 1:55:15, Let us call the first part of the audio (the desirable one) Audio A, and the remaining part, Audio B
2- Deleted Audio B from the audio track
3- Pressed shift and dragged Audio to match the length of the video hoping that it will speed the audio track perfectly to cover the 2 seconds gap
4- Played the audio clip to see if it worked; Result: weird. Instead of keeping the track contents as it is and only changing the speed, it somehow resurrected some contents from the Audio B. I thought I had deleted that . So now it plays the same length as the video, but with added audio contents at the end, so the problem remains where it was.
5- Pressed undo, to instead try the Speed / time-lapse dialog on Audio A. Right clicked audio A, clicked on Speed / Time-lapse and entered the time for which it should play directly.
6- played the audio clip to see if it worked; Result: same as 4.
7- Pressed undo again, and tried reducing the speed this time instead of entering the exact time manually. Even 99% stretched the video way beyond the length of the video (as I expected) but strangely enough the contents from the deleted Audio B are still appended at the end.
8- This time tried to shrink the stretched audio to the length of the video by using Shift+drag. And it works perfectly for the stretched clip, but that had the audio contents from Audio B anyway. So the result is exactly the same as 4 & 6 . 9- Trying to delete the unwanted audio bits at the end of Audio A from Audio B, and then stretching the Audio A to the right length actually reduces the Audio A further down, deleting some part of the wanted audio too :S ... thus just turning the problem upside down ..
I am using Corel videoStudio X5 Pro with Service pack 1.
I have recorded my bowling action (the English game of cricket, where you throw/bowl the ball the the batsmen). It was recorded side on to my run up. I wanted to measure my speed, so I thought, using 2 consecutive frames from movie maker, giving a time of 0.04 sec. Then using Pixlr(free photoshop), overlap the two frames, and measure the pixel distance the ball has traveled. Then I use the diameter of the ball (known) to measure how much distance each pixel is in real life. Then I calculate speed.
This should be accurate, with the only uncertainty coming from the pixel measurements. The results so far have me questioning if there are other factors I have missed, I got most of readings at 40mph, this is very slow, spinners bowl at this speed, I have been told I am faster, then I have one reading at 75mph. The fast one showed really good technique, so is why is that fast, but the slower ones shouldn't be that slow.
I don't know why Corel made this program without the ability to change the playback speed in project view. You can only change the speed on each clip. When you have 50 or more clips, this can take all day, when it could take a few seconds if you can do it in project mode.
Does a Sata hard disk drive of 5400rpm allows successful capture of video via Firewire. I checked the boxes which v10+ and Pro X3 but they do no state this.
I am contemplating purchasing a notebook which has a Sata HDD of 5400rpm and Intel Pentium Centrino Duo (dual core 1.83GHz) - the CPU should be fine I think but what about the HDD? I think that when I first started video editing (VS v 6 I think) that I only had a 5400rpm drive and had no problems but just wanted to be sure. Oh yes the notebook does have a firewire port.
I know how to change the playback speed of a video clip in my project, but is there a way to have it smoothly transition? For instance, can I have it go from 1x to 3x over a period of 2 seconds or must I jump directly from 1x to 3x (or manually break the files into dozens of super small chunks and manually increase each one... which will still not look smooth)?
