What you are talking about is upscaling and any current HDTV will do upscaling automatically. Upscaling doesn't work miracles though, it will only make it so that the lower quality signal can be watched on a higher quality display. It just multiplies the pixels so that a 720 by 480 (.9 pixel compressed) signal for example doesn't end up only taking up 1/4 ...

I think pretty much every editing program would allow you to zoom, pan and insert text. Inserting another video into the main video is a little more complex and the only program I know for sure that does it is After Effects. But I'm sure there are others that will. I would suggest using Premiere because it's a very powerful program. Even though I've never ...

The cabling is likely your problem. The composite cables you're using (red, yellow, white) will only move analog signal from the set top box to the TV. Likewise with RG59 or RG6 (coaxial). While both varieties of cables there are technically capable of passing digital signals (they don't care... they're just dumb cables), set top boxes typically only ...

It uses a lower data rate (within the TV, not for the actual signal) and is cheaper to produce. That is all. The only difference is that if you are going to view it on a 1080i display, then shooting in 1080i would look slightly smoother since half the information updates every half a frame rather than updating the whole thing at once, but 1080p is ...

I assume the actual data rate is 3.3 Mb/s, not MB/s (bits, not bytes). This is very low for 1080p60, and artifacts are likely at such a low rate. You might consider capturing at at least double that rate. Alternatively (or also), halving the frame rate to 29.97 would double the effective bit rate. You would be trading some motion artifacting for less ...

I don't use CS4 but in CS5.5 you can do it this way: Open the Composition dialog, open the Settings tab, and choose Custom as preset (this should be the first entry). Now you can change all parameters. To save you preset, click the button Change preset at the lefthand bottom.

Unacceptable is in the eye of the watcher, so that part is tough to answer. Distinguishable is easier: yes, there will be a difference. It will not be obvious in every frame or circumstance, but it will be there. If you simply truncate the lowest bit, it will raise the noise floor and the effect will be most evident in low light areas. So, it will look ...

Use Mpeg Streamclip, its an industry used conversion software that is reliable and fast, and free

The parasites you talked about is called noise. The setting you can change to get less is called the ISO. It corresponds to the old ASA value we had before the digital age. We can't see a thing, we can only see light. That's the way the universe is built up. Same with the camera. It sees the light reflected off surfaces. So white objects reflects all light ...

Drives are definitely the answer. My miniDV setup worked fine with 5400rpm, but HD playback looked like internet video from 2004. Upgraded to 7200rpm internal SATA drives, and ~most~ of the time, I've got good results. While I've never done any work with SSDs, I suspect those would be the ideal circumstance. For external drives, I've used 5400rpm USB2.0 ...

If you have a 8 core CPU I'd bet it is a fast one too, so that shouldn't be a problem. 16 GB is more than enough for HD, and DDR3 should ensure the speed. The GPU shouldn't have much to say as long as it's not crap. If you have 6 slow harddrives, it would be a bottleneck. You should have at least 7200 rpm disks!

I reviewed the specifications for the Samsung HMX-Q10 and have to say there is not a whole lot of information e.g., optics has no mention of "Minimum Focus Distance". So we are pretty much in the dark on the near boundary of the depth of field. (a little rant on auto-focus) Most auto focus systems have two modes: Single AF and Full-time AF. Single AF ...

The most easy to use Video Editor I know is Magix Video Delux It has HD capabilities, a lot of fixed crossover effects. My mother swears by it and she still has trouble sending mails and stuff. For more advanced users, there's even the option to go in timeline editing, but most of the things you can do in a block overview what you just drag & drop ...

Sony Vegas is my second option to Final Cut. You can do everything you need in a very intuitive interface. Like Chard says, there are hundreds of tutorials online that take you step by step through the process and many good free video editors around.

Either Avidemux or FFMpeg+Avisynth(+Avanti) will do the job. The former should be faster to get going.

A common problem for a slow edit is incorrectly setting the codec of the sequences. Unless under very specific circumstances (of which I'm not sure of), you should set your sequence codec (when you create the new sequence and Premiere asks you what preset it should use) to be identical to your footage.

Native resolution is always better than non-native. If it only has a resolution of 720p, then it would have to be down-converting to that resolution which means it has to blend pixels which can produce artifacts from the pixel blending. (Notably, softer edges is the most likely.) Update: I'm sorry, re-reading, I noticed that it isn't native for either ...

I have no practical experience, but you might take a look at using a (linux) computer with blackmagic decklink or intensity pro card. There are command line tools like bmdtools which (should) allow you to interface the capture card. https://github.com/lu-zero/bmdtools You could then pipe the video input to ffmpeg to record. I don't know of a setting to ...

There is no way around needing more data rate to capture that much video information. It sounds like the camera probably isn't actually capable of delivering 1080P/60 but that they use a very low quality version so they can slap the label on the box. Data rates are generally measured in Mb(bits)/sec rather than MB/s, but even if your suggested rate ...

They both matter. What really matters is the combination of the two. Scaling always produces a loss of quality unless you are using an even multiple of the resolution. This is because interpolation must occur during a scaling operation that isn't an even multiple or divisor of the original resolution. This is due to the fact that some pixels must ...

If you're only delivering to the HTC One mini, then yes, screen resolution overrides source resolution, as you put it. Your assumptions are correct about 1080p video either having to be scaled or cropped to fit the display, and you're right, whether the source media is scaled or cropped does depend on the playback application. As a general rule, you ...

It is unlikely to be noticeable. This is basically the principal on which steganography operates. It changes the least significant bits in images and video such that there is not a noticeable change in the final image, however software can later pull out the data without it being obvious that the data was there. Without access to the original image it is ...

FFmpeg can do this. By "FLV (Flashvideo)" I assume you mean "FLV1 / Sorenson Spark / Sorenson H.263". Not sure why anyone would choose this these days over H.264. Example: ffmpeg -i input -c:v flv1 -q:v 2 -filter:v scale=iw/2:-1,hqdn3d output.flv What the options mean: -c:v flv1 Choose the encoder named flv1 -q:v 3 Quality level. Range is 1-31 (for ...

Regarding this part of the question: "Can I achieve this kind of dark image with my cam (or maybe it is darkened in post production ?)" This looks like post production work and Vegas can do this. There are two things going on in the video to make it look dark. One is the use of a border or frame that is feathered on the inside edge and totally black at the ...

The parasites you are referring to is actually called 'noise'. Digital noise comes from two main sources. The first being the inherent noise in the camera's sensor. This is exacerbated by heat buildup on the chip from multiple exposures or long exposures, or by having many photosites clustered onto a small chip. This is why dSLRs have less noise than ...

If you're missing the presets (which is what it sounds like) I have a solution for it here. It involves uninstalling the CS suite, then reinstallling premiere as a standalone OR you can just click on help>update (if that option is available for you). There are a few tools you need to download as well to clean it from your registry after uninstalling. The ...
