About Meyer Library
* Drop-in computer lab with image, audio, video editing support
* Demographic: Students, staff, and faculty. Everyone from 1st time users to very experienced users.
* Free overnight checkout of camcorders (including Canon HV30), external hard drives, Macbooks, AV cables, etc, with SUID card.
** Supplies are limited: Currently 5 HV30s, 20 SD camcorders, 10 Macbooks.
* Influx of students from Stanford Film Society and Journalism
Canon HV30
* If you remember nothing else: HDV native capture, Compressor workflow: http://support.apple.com/kb/HT2410
* Many of these specs also apply to earlier HV20
* Func:Menu:Rec/In Setup: HD Standard:
** HDV (60i)
** HDV30 (30p)
** HDV24 (24p)
* Cine Mode optional (gamma adjust + ?)
* Remember that HDV records as 1440x1080.
** Scales to 1920x1080 square pixels later.
* Data rates:
| Codec | Rec Mode | Mbps | GB/hour | Notes |
| HDV | 720p30 | 19.2 | 8 | Very few consumer HDV camcorders record to tape as 720p30. |
| HDV | 1080i30 | 25 | 11 | Most common recording format for HDV camcorders. |
| ProRes | 1080p24 | 117 | 53 | "Film Look" that this presentation will focus on. |
| ProRes | 1080p30 | 147 | 66 | Most typical conversion format prior to editing. |
| 8-bit 4:2:2 | 1080p30 | 994 | 437 (!!) | Thank goodness for ProRes! |
* iMovie 08/09 import:
** Either "Full" 1920x1080i or "Large" 960x540p using Apple Intermediate Codec (AIC)
** Random Tidbit: iMovie 08/09 will only work directly with HFS volumes
* Final Cut Pro 6 import:
** Capture as HDV or ProRes directly (since v.6.0.2)
** I've had tons of problems using HDV Log and Capture, but normal Log and Capture works for me.
* Now we want to do all of the deinterlacing and frame rate "conversion" before editing.
* HV30 uses 2:3 Pulldown for 24P
** Recorded on tape as 60i for maximum compatibility.
** Basically need to find a workflow to throw away 2 interlaced frames, keep 3 progressive frames, throw away next 2 interlaced frames, keep next 3 progressive frames, ...
* If you forget everything else, remember this HDV native capture, Compressor workflow: http://support.apple.com/kb/HT2410
Discussion Notes
Q: Any direct to DVD cameras at Meyer?
A: No, we're pretty entrenched in miniDV.
Q: Do you use miniDV decks in workflow?
A: No. Consumer camcorders are cheaper than decks. For our users, even when we had the option to use decks, they generally used the camcorder anyway.
Q: Does Meyer carry digital still cameras?
A: No. We try to provide equipment the typical user is not likely to already have access to.
Q: How do you conform HD footage to SD?
A: Letterbox or else crop to 4:3 aspect ratio.
Q: Is USB 2.0 or FireWire 400 better for video editing?
A: USB 2.0 transfers 480 Mbps and FireWire 400 transfers at 400 Mbps theoretically, but most people agree that FW is just faster. FW 800 is even better...
Q: How many people are teaching video production / post-production classes on campus?
A: Good question! We should get together and pool resources, compare notes.
Q: Ideas for future VMG events?
A: capture cards (hdmi) and demo the new Mac Pro
