How good is the video quality on modern HD camcorders?

HD Video - Seriously, who knows this?

  • So I've bought two camcorders in the past year. Each around $800. (Canon Vixia and Sony Handycam) Video's great, but they both record in god-awful .mts or .m2ts format. I can edit them in Adobe Premiere but there's a significant quality loss for any bitrate lower than say 25 - 29mbps. My question is - How in the world do movie producers get hour long videos to down under 1gb? A super high quality HD porn vid is like 1gb for 60 minutes. ONE minute of HD footage at the highest settings with my cam is around 1gb. That's outrageous! Help!

  • Answer:

    There are 2 stages to making your video - the render to make the final product, and everything that happened before that. The final product is exactly that - it's not going to change, so you can apply as much compression as the quality will allow. With modern formats like H.264 which allow both variable bit rate and variable frame rate that's a lot of compression. Prior to that final render you're constantly changing the video - cutting bits out, changing colour balance, etc, and these all need the video to be as uncompressed as possible. For professional work, while the finished video may be very highly compressed, it wasn't shot or edited that way.

for starters, people that shoot and edit HD video for a living don't use the mts format. That's strictly consumer. You need minimum prosumer equipment for this type of work. avcHD is the most compressed format that's used and the stuff still looks great. most professional editing systems can use this format. fully uncompressed 1080i video is 480 gigs per hour. That's 8 gigs per minute of video and audio. 1920 x 1080 pixels is alot. this is per frame of video. There is 24 - 60 frames of video per second depending on what format you use.

You should start by reading up on HD video formats. Depending on what compression you use determines the size of the final video. 1 GB for 1 hour is VERY compressed HD video. Uncompressed HD video (like what's being shot by your camcorder) is 328 - 410 GBs per hour, depending on how many frames per second your shooting in.

HQ HD vids are NOT 1 gb for 60 mins. I think you have your facts mixed up.
