    Why the Canon HV20 is a poor choice for car mounts

    The bottom line is that the HV20's single CMOS imager has a rolling shutter (i.e. it doesn't read one entire frame at a time - instead it reads the top line first, then the second line, then the third etc etc). This produces nasty artefacts when the camera is vibrated. The resulting images look a little like jelly.

    Wide-angle adapters

    Not all wide-angle adapters produce barrel distortion. Aspheric adapters are particularly distortion free. The "Bolex Aspheron" (or some-such name) is apparently "the best wide-angle adapter" available. But you have to make your own housing for it and it costs about £420.Tom Hardwick over on knows lots about aspheric lenses. Wittner-Kinotechnik in Germany sell aspheric adapters

    There are loads of threads on about wideangle adapters


    Tests and thoughts about de-interlacing footage using Premiere Pro and aviSynth

    I've made quite a few notes over on this thread on The main observations are:

    Timelapse photography

    Control of cameras for time-lapse photography

    Using PICs

    PICs (programmable integrated circuits) to have timers etc so it would be possible to make a decent time-lapse controller using a PIC but it would take a lot of effort to programme. Advantages: low cost, lost power consumption. Disadvantages: would take ages to develop, would only work with a camera that I'd hacked, would only control one camera, can't be network-attached, can't control camera settings etc

    Using a laptop


    Runs on Linux, supports loads of cameras, is scriptable

      DVCproHD in Premiere Pro

      How to edit DVCProHD in Premiere Pro? Several options:
      • Serious Magic DV Rack HD (Serious Magic was bought by Adobe and DV Rack will be included with Premiere Pro CS3 and re-badged "OnLocation". Not sure if OnLocation will support DVCProHD - here's a thread on The Cow).
      • Cineform Aspect / Prospect HD
      • RayLight
      • Ingest as uncompressed onto AJA HD card.
