Ok, this how it takes a lot of time
So far the timeline for the Battleshed DVD.
Upgrade computer to suitable handle HD video editing
Find, aquire and become familiar with suitable HD video editing software
Atempt to capture video
Fix problems where it is not wokring / dropping frames / generally crapping out.
Note, two cameras so double the footage
Cut out each individual fight as I reveiw the footage for dropped frames etc.
Review footage, choose angles, sync etc
- now this is the real time killer, I am sure i could do it much faster but I am picky and will tend to review stuff a lot to make sure I have the best shots
Downconvert each finished HD fight file to SD for DVD.
Build DVD menues, extra features, blah blah.
Burn countless copies of DVD's
All fairly straight forward. One major problem for me is that while it is easy to say that I can do something else while the video is capturing, converting, burning etc it is not that simple.
For example, capturing a tape. So you set it up, start the capture. It is doing its thing so I can go do something else. Unfortunately I have very few things to do that involve being around my apartment for an hour. Maybe I could relax and play a game or watch a DVD? Oh wait, i do both those on my PC, so no can do. Most things I do involve being elsewhere for longer periods of time.
So anyway, I set it to capture, go out, work on cars, etc etc. Thats fine, I figure I can at least get one tape a day. Then I come back and find the program froze, it didnt work, workmen turned off power to my building etc.
Eventually I do get the fights on the PC, but it takes time.
If I am home, I am usually sleeping, eating, or spending time with my wife. I am not even home right now!
I am sure it is possible to get videos done far faster, but in my experience these things take plenty of time in large blocks. I don't have it, so things progress slowly.
But, thats what Xmas holidays are for!

In theory HD is the same as SD to capture edit and export, as it is just using higher compression to store more info in the same amount of space.
However, I practice I have not found that true at all. There could be a number of reasons but most likely -
The programs needed.
For example, during my time at Uni at used a 3.2 GHz P4 and Adobe Premier to happily edit SD footage, including the original Battleshed DVD. During that time I upgraded my camera to an HD model and found that my computer struggled to capture and edit the footage properly. In order to manipulate the HD footage I had to upgrade to the latest version of Premier and it ran badly on that PC even with SD footage. It wasnt till after I got married and got a new job that I put some funds into a new PC that handles Premiere fine.
The HD codec itself.
While the footage takes up the same amount of tape and HDD space as SD it uses a different codec to handle the extra compression. That codec does work the PC harder than the codec for SD, as you would expect since it is doing a lot more compression. I suspect part of the problem is once again just the program itself, but the HD codec does need more CPU cycles to get the job done.
Uncompressed footage.
Depending on what you are doing it is often best to work with the uncompressed footage. Obvioulsy this isnt going to be something really worthwhile for Robotwars footage, but for things like adding CG effects you will get best results working with uncompressed footage. As expected HD footage uncompressed is much much bigger and does require more processing power and storage space than uncompressed SD.
Capturing
HD footage recorded to miniDV has a weakness in that if a single frame is dropped from capture the way the compression works causes you to lose 15 frames, over half a second. This is very significaant and can totally ruin a shot. Dropped frames can be managed by using high quality tapes, keeping the tapes dust free and not using them more than once to record and once again to capture. While not as critical for robotwars footage HD is much more time consuming to reveiw and check footage.
Editing.
SD is much more forgiving of bad editing than HD. Minor problems such as shake, focus, framing, etc are that much more noticebale in HD over SD. While my HD footage will be downconverted to SD for the DVD I still keep a saved copy in HD and thats what I edit for. I personally find HD footage much more demanding to edit. For example at Uni some students did some editing at home in HD but only with a SD monitor to reveiw on. When they played the completed footage back on a 1080p projector they found a lot of problems they had not even seen in editing.
On the plus side recording in HD and downconverting to SD results in a much much nicer image than simple recording in SD in the first place. (at least on the cameras I have personally used) Any post processing for levels, colour balance is best done before downconverting. It is also nice to have the HD files for future use.
I know i go on about this a lot, but I enjoy all the various factors with video work. I don't profess to be good at it or to know more than anyone else, but I do try and complete anything I do in a way that I am happy with. I basically consider any footage I record to represent myself and my video work / values and as potentially useful as part of a showreel. I have probably spent at least as much time doing video related stuff for Robotwars as I have actually building and competing.
And I wouldnt have it any other way, but it does mean for now that I have a big backlog of footage. I would love to get it all online and it will happen, but it will take a while and it is not going to be on youtube.
Hopefully in the new year I can get things rolling and won't get beaten up over it by my own state, let alone other ones!
EDIT
Hmm, that was excessivley massive. Started typing before you post Aaron, but I agree, lets get this split into another thread?
I love lazy fridays at work if only I could do my video editing here hehe
