It sounds like a combination of two things from the comments discussion. First, with the very high frame rate, your laptop simply can not handle the high data rate. If you need to edit on the laptop, I would suggest re-compressing the video down to a smaller size and then when you are done, you can replace the low quality footage with the original for the ...

As an alternative I would suggest Duplicate Video Search (shareware).

The default video files made by most Canon DSLRs is an H264 video file in an MOV container. Decoding high definition video at the data rates that most Canon cameras use is intensive for both memory, disk and CPU unless you have a dedicated decoder chip. Your iPod Touch uses flash storage (which is fast) and has H264 decoding capability to make it run ...

You seem to have a fundamental misunderstanding of how video works. Video is composed of frames. You can't have millisecond precision because video doesn't have millisecond precision. If there are 30 frames per second in the video, you can only stop after one of those frames. That means your options are only every 1/30th of a second roughly.
What are ...

Adobe Encore can do what you are looking for. It is included with Adobe Premiere. You can either buy a copy of CS6 or if you only need it for the one project, you can use Creative Cloud to obtain it for just a month or two.
In general, you will find most DVD authoring software comes in fairly expensive packages. It's not as easy as you would think to do ...

Take a look at Movie Studio Platinum 12 (or DVD Architect Studio w/o video editor)

If the overlay has transparency, you could use an Add strip instead. Then keyframe the Multiply setting for it going from 0.0 (invisible) to 1.0 (fully visible).

For archiving VHS I suggest using MPEG2 720x576 as the best format in terms of quality/space.
DV is 12 GB per hour, but this is the best format for editing. H264 takes up much less space, but it is the delivery format, not for editing. MPEG2 is a compromise. In addition, you can burn them to DVD w/o reconverting.

DV has a something of a focus on simplicity, so it can be encoded with primitive microprocessors and decoded quickly in an NLE. In particular, it's intra-frame: a DV file is basically an array of still-image files.
That's useful for professional editing; it means however DV can't achieve nearly as high compression ratios as more complicated formats with P- ...

What you are looking for is called a Screen Capture program or Screen Cast program. A quick Google search turned up gtk-recordMyDesktop as an option that should work for your purposes and appears to be built in to Ubuntu. This was the site I found that explained more detail on how it is used. I personally have no experience working with Ubuntu, let alone ...

No, it is not possible. Mpeg-4 compression is based around storing information about patterns found within the video. It doesn't deal with particular pixels. Blacking out certain pixels alters the pattern and thus alters the way the video would compressed, potentially significantly.

DVD video is actually MPEG video, packed in VOB format (with audio and subtitles). So you don't have to reencode your footage. Adobe Premiere Pro and Encore are high-end software programs, not for beginners. I recommend you to find more user-friendly software (like ConvertXtoDVD or similar).

Encore should work fine for your purposes. When you look at the original source, what is the resolution? Is it still 728 by 480? Most likely the original image is using oblong pixels to make a 16:9 image with a non 16:9 resolution. This is fairly typical and is called Anamorphic Widescreen. The 16:9 image is compressed to a 4:3 size (720 by 480 is a ...

That's really a loaded question. In general, the rest of your content is going to look better if you leave the computer at native resolution and let the computer scale the video. If for example you have a video that is a slightly different size, then you would end up scaling to get the resolution setting and again to get the native resolution of the ...

I couldn't find specific details, but it appears that ancillary data on SDI in general conforms to SMPTE 291M. I couldn't find any details about the specific implementations used for deck control. It appears like there could potentially be some variation between manufacturers or even particular decks since the ancillary space doesn't seem to be that ...

m3u playlists only contains links to the media itself that you're playing.
It doesn't actually consider the srt file at all. If the software used to play back the m3u file support srt files it will look in the same folder for the same file as the video only with the extension switched to srt.
You will therefor always need to store the srt together with the ...

There are two different approaches that can be used. Motion/Camera tracking and Motion Control.
In Motion or Camera tracking, multiple non-coplanar fixed points in the scene are tracked and from that it is possible to extrapolate the position of the camera within the scene. This information can then be fed into a virtual camera used to generate the output ...

Ok, now that I was able to reproduce your technique thus far, I can fill in the missing pieces. Your use of the Track Matte Key produces a layer that is transparent everywhere other than where the mask is present. You need to layer it overtop of the video that you want behind it and you need to apply the dimming effect to the background layer.
In your ...

To do this, you would need real time encoding hardware and some seriously high speed hard drives. I know devices like the Matrox MX-02 will work for 1080p30, but I'm not sure about resolutions higher than that and at 60p. I think Black Magic Design has some 4k real time encoders but I'm not sure if they support 60p. Multiple SSDs would also pretty much be ...

It can depend on the compression used, but generally yes, there will be a loss of quality, particularly if there is any alteration to the video. For a fairly low compression format like DV it probably isn't going to be much, but the best bet, if the format supports it, is to append the stream data and alter the file such that it has the necessary format or ...

Compression is a very complex field that you can get in to either a little or a lot or anywhere in between. There are companies whose only job is to do high quality compression for major releases. Part of the trick is that there are different compression algorithms, different storage formats, different codecs and each codec has its own set of settings.

There are two main concepts that I think are key here. The first is learning about signal paths and what the functions of each piece of equipment does along the way. The second is understanding the signals themselves and how they work. In video, this can be particularly important since many signals are actually the same on different cables. In both ...

There are no filters applied there. It's pretty much basic shots, probably from a DSLR based on the feel of the video. The shots with the one guy were shot with things overexposed and then they upped the contrast to try and do recovery, but it results in large overblown highlights where there was too much light to fit in the dynamic range (the amount of ...

The easiest way I can think of would be to actually do it as multiple videos and stills. Have the first video play and then go to a still of the last frame. The next would be the next video clip followed by the still. Continue doing that for the length of it. Not sure if it works like that in Keynote or not, but that's how I'd do it in any of my ...

I tried using Miro as well to transcode H.264 MP4 into VP-8 WebM so that Firefox would play using HTML5 rather than a Flash fallback.
But at least when the mp4 source was exported from Premiere then the Miro conversion did not work properly
it finished in my case, but the webm file would always start to play from the last second of the video for some ...

If I understand you correctly, this is traditionally done by compositing programs such as Adobe After Effects. You could track the wall and then replace the wall with an image but it's going to be a lot trickier if anything is moving in front of the wall. (You would need to make a rotoscope mask to tell it where not to render the image.) You could then ...
