AVCHD vs HDV

Scott
What do you eventually end up delivering to the client? DVD, bluray, broadcast quality file?
The reason I ask is that for the theatre work I mainly do, the client wants DVD, so component+XLR out from all the cams to a vision mixer which is then recorded on a deck that receives an audio feed from the sound desk is sufficient. We recapture to PC and edit the best of 2 performances.
We have shot both in SD and HDV, but once crunched down to DVD, the difference is a slight improvement. Where it is noticeable is when there is a poor quality cam in the mix. We have used mainly Z1P’s, but next year plan to use P2. It helps when most of the team works for broadcast A/V product retailers and organisations with high quality A/V departments :-).
I am with Danny that a good quality cam that records AVCHD in HD 1920 at a data rate higher than 24 mbps may give you the results you are seeking. I am not sure the barrel cam with manual controls is suitable for your work, but I guess you have to try before you buy. For me, I have live operators controlling focus, zoom, iris and gain. We work in a live theatre environment, and with 12x to 20x zooms, get up a personal with the stage performers.
When my Z1P or FX1 goes into retirement, I’ll be looking at replacing them with something like the Sony HVR-NX5U which records simultaneously to card and the HXR-FMU128 memory unit. If my budget (and missus) allows it, perhaps I can dream of an EX1/EX3 or a Panasonic P2… * sigh *

Thanks guys,
As much as you like the Panny TM700 Danny, I need to have component out and LANC control on any cam I use. I use robo heads on 4-5 of the cams when I shoot as many are on a JIB or towers that are 11′ high…no options there. That specific panny does not have either unfortunately. I need to go component HD as well to match my cabling and I don’t have the $ to spend on HDMI amps to send them over 150′ so component is a must. I have been looking into the Blackmagic stuff and there requirements for computers and RAID arrays as well. Anyone use any of the sony AVCHD cams like the AX2000? Just wanted to check, again thanks for all your input.Scott Francis

The TM700 does have component as well as composite SD and S-video with analog stereo audio out, but it doesn’t have lanc for external control, just a remote control. To bad as it has a 5.1 mic built in that would give you some good crowd audio and if you set the Vegas project settings audio to 5.1 and drop in the native .mts file on the timeline, all of the 5.1 audio tracks show up as well as the video. I do wish it had the ilink or lanc ext. control as well as phanton power XLR like my Sony but I don’t use the audio from the camera normaly either. I use another computer with Protools for that and use the camera waveform to sync it up, then mute the camera audio. If you go with the Blackmagic Intensity card or Shuttle, defently do the research as the two main Blackmagic forums show more people can’t get them to work right or at all. I had the luxury of my work buying one first and I did my homework and got the Shuttle working the first day, then bought one and bult an i7 just for it. One very important thing about the intensity cards is the source rez and framerate must match the capture settings or it won’t capture video. It’s kind of missleading as the outputs show video when you input video even if they’re not the same rez and framerate, but it won’t capture it.

These two forums will let you know what your up against.
