DV or HDV?


Luckily me and Harry got the chance to use one of the schools 5 Sony HVR-HD1000E which is of much better quality than the cameras which we used to film last year, which were Sony Handycams.
Last year the opportunity was indeed
there to use Mini-HDV tapes over the more frequently used Mini-DV tapes. However we felt that although technically the aspect ratio would be classed as HD the actual difference (especially in the low-lighting we were using to capture the conventions set out by a thriller) noticed on screen wouldn't be worthy of the extra cost.
However this year due to the differences in filming equipment we were faced with a very different opportunity. We were filming in good light, with a much higher quality camera so visible differences would be apparent. So the question was: is it worth it?
When filming in HD you run into a lot of different problems with compatibility etc, not to mention the cost factor - where Mini-HDV costs around 10x more than a standard Mini-DV. When capturing footage in HD it is not consistently possible to capture in real-time (depending on the speed of your processor) and therefor this could hav
e in theory slowed down our capturing process - and with over 3 hours of footage to capture this would have amounted to a lot more than we would have wished to have spent on capturing.
After this you then have to look at comparability with different systems, some computers do not 'work' with HD footage if it is not correctly de-interlaced meaning two frames can 'merge' together so to speak looking like the picture to the left. This became an issue because we would then have to spend extra time exporting any finished footage (or simply footage to look at) twice, once in high definition once in standard.
Through post-production would also have been a difficult time as we were working with masks there was a lot time consuming rendering to be done, and this could have been double-y so if we had have gone with HD footage. So with an accumulation of all these reasons we decided against Mini-HDV and instead have opted for every-day standard Mini-DV.

During filming we used three different Mini-DV tapes an shot a total of 2 Hours and 53 minutes of footage.

It's good to see that you are evaluating the technologies you have available, especially getting to grips with the terminology. I like that you have linked the resulting effect to the required genre of your video.
