Thanks, feel free to move it.

I presume an 4TB external drive can be hooked up to a lap top and then easily moved to a desk computer when necessary? Is this true?

yes, it's why you have an external hard drive. by using it, you can sync all your computers, laptops, notepads, etc. When you connect a computer to it using Goodsync, Goodsync will go through all your files and update them to a newer version, or if you want, delete old files. It quickly makes a carbon copy of the computer with which you are syncing. You can also select files/folders to ignore during the syncing. This is good if you, say, have a small notepad with limited storage and only want work-related documents or perhaps the music folder synced.

I started with a 2.29 GB file with 25 minutes of footage. I took out 15 minutes of this footage (a complete waste of footage--I got dressed and stopped in a bar for a quick drink), thus reducing the file to 10 minutes. True to form, the new file is strangely large, right around the original 2.29 GB even though 15 minutes (more than 50%) of footage is now excluded.

Clearly, I'm adding something to the footage that is taking up massive space....

I've tried goggling this problem but I can't seem to locate any info about it online.

In Windows/PC, if your right click on the video file, then, look at "Details", you'll see specific information including frame width/height and bitrate. Bit rate affects both file size and quality.

Rather than explain how that increases file size, this guy does a great job:

also, good explanation:

Awesome links, thanks. For some reason, I can't access the bitrate of my files when I right click or when I open in Quicktime. I will try again tomorrow on a different computer.

I'm thinking that bitrate is indeed the culprit. The VSDC video player gives me the option of a normal bitrate or a high quality one. I always select the high quality one. I may be adding bitrate to the file, which would explain the increase in file size. I'll know more tomorrow. Thanks again!

Quicktime is an Apple product, so it's probably why a Windows (Microsoft) product may not be able to see the information. Again, AVS can convert anything to anything.

As I understand it, there are essentially three ways a video takes up space.

1. Frame size (i.e. 1920 X 1080 vs. 1280 X 720)
2. Frame rate (i.e. 30 frames/sec vs. 60 frames/sec)
3. Bit rate

If the original, raw footage is, say, 1280 X 720, increasing the frame size just makes it bigger on the screen without increasing resolution. The view can do this themselves by simply controlling the size of the screen of their media player; thus, don't increase frame size in your video editor as it unnecessarily takes ups space.

2. Frame rate is the fluidity (smoothness) of the video. Same thing applies - if you've recorded at 30 frames a second, increasing the frame rate will not make a better quality video.

3. Bit rate is how much information is flowing. It's like a series of paintings in sequence. If each painting (frame) is highly detailed, then a higher bit rate is warranted to convey the detail of each frame. However, if each painting (frame) is maxed out at a certain resolution, increasing the bit rate does not increase quality, it only increases the amount of hard disk space.

Just a couple of things I have learnt through experience. You are best to buy 2 drives! Hard drives can fail and that could be an end of the world type thing. I have 3 1TB drives and rotate them with a backup every month (in rotation). I then keep one drive hidden in the car (house might burn down).
I have also paid $1.59 a month for 100GB of online google drive to save all my photos.

This might be extreme backup but I've lost files on hard drives which failed, including a bunch of photo-shoots of my wife pre kids in her late 20's which I have lost forever and which give me nightmares of the day it (the drive) died on me. I spent $100 on trying to salvage it but it was kaput, the reader arm had come loose and scratched the disk heads to hell.

Morale of the story....... 1 backup is NEVER enough. I have 3 but 2 would suffice. Remember that this stuff is irreplaceable!

Make sure you get a Seagate, Toshiba or Samsung drive as they have the highest manufacturing standards.Ensure it's USB 3.0, USB Powered and only requires one USB port (some use 2 ports, one for power, one for transfer of data).

You da man, Brad! Thanks for figuring this out for me. The Bit Rate is the culprit. I looked at my files on another computer, and I discovered that they were 720p (I already knew that), 60 frames rate (I already knew that), and a Bit Rate of 128 (I didn't know that at all). My VSDC player is set to 720p with a 60 frames rate, and so I knew both factors were not increasing GB. VSDC offers three Bit Rate options: high quality at 224 kbps, normal quality at 192 kbps, and low quality at 128 kbps. I always use the high quality and thus I'm adding Bit Rate to files that contain 128 Bit Rate.

I edited the video again, taking out the same amount of footage. This time, I saved the shorter video at the normal bit rate of 192 and and the GB decreased!!! Based on what you say above, I should probably use the 128 Bit Rate since my videos use that Bit Rate, and a better bit rate does not improve quality. I'll know that for the future.

I'm a little disappointed to learn that my hidden camera takes low quality bit rate. I went out of my way to ensure 720p and, more importantly, 60 frames per second verses 30, but I never knew anything about bit rate. For me, the Frame per second is crucial. At 30 frames per second, slow motion gets too blurry and you miss out on reactions & elevator eyes. At 60 frames per second, slow motion is much clearer and you capture the girl's eyes.

Issue resolved. Thanks again. For the sake of organization, I'm still going to purchase an external hard drive and save and organize my material on it.

Once I move my material to the external hard drive, I will have a ton of empty flash drives. I plan to save some of my better files on flash drive. That way, if something catastrophic happens to the external hard drive, I will have backup copies of my best CFNM reaction material.

Frame rate for NTSC DVD players (used in the USA) is slightly less than 30 frames per second and PAL players (generally used outside the USA) is 25 FPS. Since movies look okay at 25 FPS, coding at anything higher is just using file space unnecessarily unless you are shooting some very unusual situations. Thus using 60 FPS unnecessarily increases the file size. Maybe it has some use if you are shooting on a fast moving bike down a mountain side.
