No audio on my camera?




Cody


I have a Coleman Xtreme sports camera. It is waterproof. I got it to record videos much like a GoPro. I have made the horrible decision to buy the Coleman instead of GoPro. I have a video on youtube and I had to replace the audio with a song because it was so bad. It is just almost no sound, Can somebody help me fix this?
It isn't crap, though. I don't buy something unless it is worth my money. It is a great camera the only problem is the audio. I'm guessing your intelligence is limited. I will try the other options suggested. Thank you all.



Answer
Depends on the audio available to capture../

The camera gets excellent reviews../
It says..it uses a 16-GB SD-card../
Try--the SanDisk 16-GB Extreme Class 10

Part# SDSDRX3-016G-A21

the better the ??? the better the video quality?

what are video cameras( like film) based off of i always assumed it was the megapixels? but i hear that that is just the picture quality? im looking for the film quality-ish ive heared about the cannon but am still looking for cheaper not so bad ones.


Answer
The better the person behind the camera operating it, the better the quality.

Real film cameras capture at 24 frames per second. After the film is exposed, the film is sent to a processing company. The processed film can be edited directly or each frame is canned and digitized for computer based editing.

Video cameras come in two versions. Studio cameras send video signals to a "production" room and the video is recorded to video file servers. Usually, these cameras have no audio capture storage; and they rarely have local video storage capabilities. If you watch TV gameshows (Jeopardy shows their cameras and audio mixing board regularly) you will see these studio camera. Many TV news broadcasts and pro or college sports broadcasts show these cameras a lot, too.

Camcorders usually have local video and audio storage. They can record analog or digital video - depending on the camcorder. Today's digital camcorders basically allow light in through the lens, the light hits an imaging chip, the light is digitized and written to storage media - digital tape, flash memory, hard disc drive are most common. At the point that digital information is written is where the 24 progressive frames per second needs to happen. *Most* consumer and prosumer video cams (camcorders or dSLRs) use a digitally derived 24p capture - they really capture at NTSC standard 30 fps, but have a "drop-down" to eliminate certain frames to provide the 24p spec.

The camera or camcorder is only part of the equation. Because of the dropdown process, the video edito needs to be able to deal with that frame elimination to maintain the frame rate continuity. This should provide you *some answers on the "film-look" and you need to do more research.

As for "video resolution" and quality... there are multiple contributors to that - not just one.

Video is measure in horizontal line count... not megapixels. Megapixel count is a resolution measurement for digital still images. With video, 480 horizontal line is standard definition video.. For high definition video horizontal line count is either 720 or 1080. Anything past this is "ultra high definition". On top of this, the amount of data compression applied to the video will define the video quality... For example, low compression standard definition video will look a LOT crisper than very highly compressed high definition video.

The Canon HV40 and the HF S series are worth a look at the low end. Less than this and video quality (and audio control) will suffer. The Sony HDR-CX900 is worth a look as is the Panasonic HDC-TM900. We assume your computer and computer editor can deal with connecting to and dealing with the video captured by these camcorders - including the various drop-downs they use to achieve their 24p capability. As well, the video editor needs to be able to output - render the video file to 24p... many cannot. Final Cut (Macintosh) and Adobe Premiere Pro (Windows, Macintosh) and AVID (Windows) can... some others can, too.

As for the first line in this post... I know skilled, experience people who can make an awesome video using the least expensive video image capture device available... and I know people who have no skill or experience who would create garbage video with the most expensive equipment available. This has nothing to do with video resolution - but has lots to do with understanding the capability of the equipment being used and staying in that useful window and not trying to use the equipment in a way that it was not designed to be used.
