Variable Frame Rate Function Enhances the Image Expression

Variable Frame Rate — Also Supported in 1080p Mode

The Variable Frame Rate (VFR) function was inherited from the Panasonic VariCam, which is widely used for producing movies, TV series, and TV commercials. It creates a wide range of film-camera-like images, such as overcranking for slow-motion and undercranking for quick-motion effects.

Image Modes and Variable Frame Rates

1080/59.94i, 23.98p, 29.97p: 1/2/4/6/9/12/15/18/20/21/22/24/25/26/27/ 28/30 fps (frames per second)

1080/50i, 25p:1/2/4/6/9/12/15/18/20/21/22/23/24/25 fps

720/59.94p, 23.98p, 29.97p: 1/2/4/6/9/12/15/18/20/21/22/24/25/26/ 27/28/30/32/34/36/40/44/48/54/60 fps

720/50p, 25p:1/2/4/6/9/12/15/18/20/21/22/23/24/25/ 26/27/28/30/32/34/37/42/45/48/50 fps

•Normal cinematic shooting (at 24 fps, 25 fps or 30 fps) refers to the same rate as used in film cameras. The AG-HPX255/HPX250 can record in 24 fps. Note that 25 fps and 30 fps are the standard frame rates used in the production of TV commercials, music clips and video media.

•Overcranking (higher-speed shooting) produces a slow-motion effect. This is especially effective for high-action scenes like car chases or crashes, or to create a dramatic impact in a scene. For example, when a scene is shot at 48 fps and played at 24 fps, a slow-motion effect of 1/2x is attained.

•Undercranking (lower-speed shooting) gives you a quick-motion effect. This technique can be combined with a warp-speed effect to give special emphasis to flowing water, fast-moving clouds, etc. For example, when a scene is shot at 12 fps and played at 24 fps, a quick-motion effect of 2x is attained.

Versatile Recording Functions Enabled by File-Based Recording

Clip Thumbnail Display and Clip Editing

Recorded clips are automatically allocated a thumbnail image and metadata. This lets you display the thumbnail images on the LCD monitor, delete clips, and confirm or edit metadata (using the built-in Software Keyboard function).

•Last clip delete: The clip that was most recently recorded is deleted with a single touch.

•Rec check: The beginning and ending of the clip that was most recently recorded are checked with a single touch.

Shot Marker and Text Memo*1

•Shot marker: Clips can be marked during or after recording. When mounted to a PC,*2 the user can display only the marked clips if desired.

•Text memo: This lets you post a memo on any scene of any clip, up to 100 memos in all, similar to a sticky note.

*1: Shot marker and text memo cannot be used in loop rec, interval rec, or one-shot rec.

*2: When using P2 viewer, a Windows PC viewing application that can be downloaded free of charge by P2 users. See the following website for details. http://pro-av.panasonic.net/en/sales_o/p2/index.html

One-Clip Rec Mode

Whereas normal Rec mode produces a clip for each Rec start/stop cut, One-Clip Rec mode records up to 99 consecutive cuts as a single clip, which greatly improves the nonlinear editing work that follows. A text memo is automatically attached when recording begins, making it easy to find desired cuts within the clip.

Recording Modes That Meet a Wide Variety of Needs

•Loop rec: This repeatedly re-records a particular recurring time slot, always maintaining a recording of the most recent period.

•Pre-rec*:While in standby mode, you can continuously store, and subsequently record, up to 3 seconds in HD (7 seconds in SD). This will help you to get the shot you want every time.

•Interval rec*: This gives you automatic intermittent recording based on a set interval and recording time.

•One-shot rec*: This frame-shot recording function is useful for producing animations.

•Time stamp: The date and time can be stamped onto recorded images. Commonly used for evidential images.

* These functions cannot be used during Variable Frame Rate recording.
