The squares in a row on the right represent the buffer memory of your camera. When you are recording video the data goes roughly as follows: Sensor -> Buffer memory -> Memory card When the last square turns red it means the buffer is full. This is caused by the fact that the buffer memory could not move it's contents to the memory card fast enough. ...

That's EIA-608 analog closed captioning data. It should be on line 21, which is within the vertical blanking interval of the SD signal. Either the line was shifted down or the VBI was captured as being active video.

Here is what I do (for my videos on http://www.youtube.com/user/killergege). Tools : Software : Reaper for audio recording, Sony Vegas Pro for video editing Hardware : a camcorder, an audio interface (POD HD500 in my case) Process : I create a new project in Reaper and Vegas and setup everything to record audio properly on Reaper through my audio ...

I don't have experience with that particular Samsung camcorder, but I did do some long term recording on an older Samsung camcorder. My camcorder had a time lapse mode that allowed it to capture a frame every minute or so. It would record while plugged in to A/C power. Although the camera used the FAT32 filesystem with 2GB file limits, it was able to span ...

Short answer: no. Long answer, maybe. You have very limited scripting ability via the auto update function of the camera. You simply drop a text file called "autoexec.sh" on the SD card before turning the camera on and the camera will execute the script. Though I haven't seen a script that would do something like infinite recording by erasing the oldest part ...

It is best to match the source dimensions with your recoding dimensions. Using a larger number of pixels requires more data or bandwidth to encode the scaled source. You wont be able to make a sharper image as there isnt any additional information being generated and in fact the scale up might make the image softer or add artifacts like aliasing.

The reasons for an automatic stop are either reaching the 30 minute limit (thank you European Union video camera tax that ends up impacting what's available to most of the rest of the world), hitting the 4gb file limit (file system limit for the OS on the camera), the sensor is overheating (high usage + temperature) or the buffer is being used up (memory ...

Deciding whether or not to shoot interlaced is really a matter of matching your destination format. If you're shooting video for the web, you should record it in progressive scan mode. You can record interlaced, and then de-interlace it in software, but this will likely lead to video artifacts, especially considering your subject matter. I think the ...

You can use any microphone for any instrument. However which one you use will depend on your specifics - is the instrument going to be moving, do you want to be very directional to just record one out of an orchestra, do you want an omnidirectional mic to record a group of instruments? Do you want to record the vibration of the wood through a contact mic, ...

While it is true that you can sometimes gain additional sharpness by recording at higher resolution and then downsampling after you have finished any other changes you plan to make, that isn't applicable in this case as your source material is only 720p. The only reason that downsampling matters is that it can make sure that information that would have ...

If you want the “best possible results” I would recommend the following workflow, or similar variation thereof: Export your captured video source to a JPG Image Sequence. This will create a JPG for each discrete frame of the video. If you want ultimate color control, with no loss of quality due to JPG compression, you can export instead a TIF sequence, but ...

Unless the DSLR/Mirrorless camera you are using outputs 10-bit 4:2:2, using an external recorder to up-convert the footage to ProRes HQ will not result in a better image quality than what the camera is able to produce/output. If anything it will allow you to edit and re-compress the footage multiple times without losing the original quality. Using an ...

A typical solution is to create better acoustic isolation between your keyboard/controller and the microphone. The thing that really stops sound waves is not foam itself, but mass. Eight ounces of foam is nothing compared to 8 lbs of rigid fiberglass. Another solution is to use a downward expander. This audio-processing device (which can be an external ...

Google has supported 60fps video since 2014. YouTube has a page that talks about video formats, codecs, framerates, etc., here. It is up to the Browser and YouTube to negotiate what format, frame rate, etc., should be served for optimal playback. If you only care about YouTube as a video display platform, and not at all about any other platform, then you ...

Both RED and Alexa cameras offer this feature, and the Sound Devices PIX 240i reads it. But nowhere on the Internet is there any documentation that your SONY camera offers this feature. Either SONY doesn't have it, or they greatly need to improve their documentation.

When overwriting happens, usually old file is removed. So, new file size is around 0 bytes. Here nothing to rescue. If you realized your mistake ASAP, in a few seconds, you can press RESET button. You will lost everything unsaved. Perhaps, even file system commit with new data, so old data will be here. Otherwise, your file lost. You can try to recover ...

You could both record your individual screens and microphone inputs. In after effects (or another program of choice) you have the ability to separate the audio and visual so it is possible to change perspectives without affecting the audio. This would probably require a little manual adjustment of one of the audio layers given the lag of skype. Good luck!

None. If you want low CPU/GPU usage and small file size, you need a hardware encoder. Period, end of story. Games are CPU/GPU intensive and video compression is also exceedingly demanding on CPU/GPU. Programs like FRAPS capture video smoothly by postponing the compression until later and instead save video as very large, minimally compressed files. This ...

This is really the same trick as what is needed for a music video. There are two options for it. If you want to record the actual performance, play the backtrack while recording the video and synchronize it after the fact. You can either directly mic the instrument and play the backtrack aloud or you can use headphones or in-ear monitors to play the ...

You can record video upside down, and then flip it using PC software. Eg. Avidemux, which is freeware can flip videos. For sports or action, GoPro Hero is very good camera. I can stream to PC or Mac. It also can record upside down. And there are a lot of accessories to mount it in many places.

Verify again that your source is indeed a stereo source and that your cabling is TRS cabling. I own this same camera and have been able to record audio in full stereo and also on only one side of the stereo spectrum.

According to the Using Commercially Available Microphones section on page 76 of the manual for the HF G20, it should be possible to connect a stereo microphone to the external mic connection. There may be some problem with the kind of a source you are using or the way you are connecting it.

If you are actually using a component cable (3 or 5 connectors with 2 more for audio) then you should be able to do HD signals unless your capture device or source device is limiting you. Based on the SD resolution limit, it sounds like you may actually be using a composite cable though (1 yellow cable for video and a white and red cable for audio). ...

This is just a crop effect (also sometimes called picture in picture or size and position). Any video editing software that supports layers and layer resize can do this, though the exact approach varies from software to software. It is a very basic thing to do and just involves bringing in each of the video clips as a layer, synchronizing them time wise ...

This was a feature on some Mini DV camcorders back in the day. I know the Canon GL2 supported it, but as I recall I think it also required a MiniDV tape with a circuit in it that cost extra and I'm not sure if you can still get them anymore. Having to deal with capturing tapes is also a bit of a pain. If you don't mind a momentary break in the footage, ...

If the camcorder records stereo sound and you are only interested in mono recordings, the foot switch could trigger an oscillator that injected a short tone on the left channel and the inverted tone on the right channel. During regular playback where you might be mixing left and right audio to one mono audio signal, the tone will be unheard because of ...

The focusrite scarlet 2i2 has no inbuilt mic, you need to connect an "external mic" to it, or connect the guitar lineout to it. If you have effects pedals, just connect the last 1/4" connector n the chain to the input of the Focusrite. Please update why you are having sync problems. Anyway don't not rely on a webcam to give synced audio/video. I would say ...

FRAPS gets its speed specifically because of the large file size. When dealing with video you have two conflicting goals, low CPU usage vs low space usage. To use less space, more compression must be applied. To apply more compression, more CPU must be consumed. If CPU consumption gets too heavy, it impacts performance of games. Thus FRAPS goes to the ...

There isn't really a good answer to that. There isn't a whole lot you can do with a fixed shot and making adjustments on a live shot is always a danger of being distracting, even when controlling it by hand as an experienced operator. Making adjustments via a Pan Tilt Unit while the camera is live is going to be anything but smooth and will be very ...

You are hitting a bottleneck of some kind - from your description it is hard to see whether it is CPU or I/O based, but things that could well be culprits: You are only running with 3GB of RAM - this is pretty low. The Java engine can require large amounts of RAM. I play a fair bit of Minecraft and 8GB really helped me out! A Core 2 Duo is not exactly ...
