Does telecine affect the playback speed?
The difference in speed is imperceptible to the viewer. For a two-hour film, play time is extended by 7.2 seconds. If the total playback time must be kept exact, a single frame can be dropped every 1000 frames.
What does reverse telecine mean?
Telecine is the process of converting motion picture film to the NTSC video format used in broadcast television. This process is known as reverse telecine. An additional benefit of restoring the original is that it’s easier to convert this to PAL, the European broadcast standard, which uses a 25 fps frame rate.
What telecine means?
: the equipment used in the process of transferring a motion picture to videotape or converting it into television images also : such a process.
What is telecine quality?
TELECINE (TC) : A telecine machine copies the film digitally from the reels. Sound and picture should be very good, but due to the equipment involved and cost telecines are fairly uncommon.
Which frame rate is most notably pal?
PAL and SECAM use 25 FPS in Europe and in Japan they use 29.97 NTSC. This is the universally accepted film frame rate. Movie theaters almost always use this frame rate. Many high definition formats can record and play back video at this rate, though 23.98 is usually chosen instead (see below).
How do you detect telecine?
Watch the bottom of MPlayer’s output to see these messages. You should check the “30000/1001 fps NTSC” sections to make sure they are actually telecine, and not just interlaced.
How does a telecine work?
A telecine is designed to work in real time. The film is played back at normal speed, captured at video or HD resolutions in the proper color space, color-corrected in real time, and written to disk or tape. The speed at which the film is transferred is the native speed of the recipient video format.
Is Hdtc good quality?
However, the result is inferior since the source material is usually a lower quality copy reel. Telecine machines usually cause a slight left-right jitter in the picture and have inferior color levels compared to DVD. HDTC is used to label a High-definition video recording.
Should I use inverse telecine?
If your video player doesn’t have direct hardware controls, you should enable noise reduction and inverse telecine. For most video, keeping noise reduction at around 25 to 30 percent is good enough.
How can I get rid of judder on my HDTV?
The “120 Hz” HDTV sets will remove the 2:3 frame repeats from 59.94 inputs resulting in 23.976 film rate. Then these frames are repeated 5x to 119.88 fps free of judder. The same is done following inverse telecine or from direct “24p” inputs from some Blu-Ray players.
What causes judder in a telecine video?
The thing about telecine is that it uses 3:2 (or 2:3) pulldown, and CREATES this kind of non-steady motion. To some, this is very noticeable, and just compounds the jerkiness quality that people may already notice about lower framerate presentations (24p – cinema, or 25/29.97/30p video).
What’s the frame rate on a 29.97 telecine?
For 29.97 telecine, they will first inverse telecine to 23.976p, then frame repeat 2:3 to 59.94 fps. The “120 Hz” HDTV sets will remove the 2:3 frame repeats from 59.94 inputs resulting in 23.976 film rate.
Is it OK to watch movies with judder?
24p judder only matters when you watch movies, so if you don’t watch movies, you have nothing to worry about. Overall, 24p judder is not a major problem; most people will never even notice it. If you’re wondering whether it’s an issue for you, take a look at this video and compare the look of 24p with judder (left) to judder-free 24p (right).
