movie formats
Posted: Sat Aug 02, 2014 2:03 pmHi,
When I tried to play a 1.5GB movie in MKV format, there were two problems.
First off, my iDevice is the Apple iPad 3rd generation, 32GB, Verizon cell.
The aspect ratio was wrong. The aspect ratio was correct in other players. Data from an info page in another player
gives the following info:
general
format : matroska, webm
bitrate : 2048 kb/s
video : h264, yuv420p, 1920x800 [SAR 1:1 DAR 12:5], q=2-31
audio : eng aac, 48000 Hz, 5.1, fltp
metadata : title is "blahblah 2013 1080p BlueRay 264-SPARKS (1)
from IMDB :
Video
Codec: MPEG-4 AVC (21.82 Mbps)
Resolution: 1080p
Aspect ratio: 2.40:1
Original aspect ratio: 2.39:1
Audio
English: DTS-HD Master Audio 5.1 (48kHz, 16-bit)
disc : Blue-ray, DVD, ultraviolet
time : 91 minutes
If I get this right, the aspect ratio is about 12:5, which is not on OPlayer's list.
From Wikipedia's Aspect Ratio :
"The most common aspect ratios used today in the presentation of films in cinemas are 1.85:1 and 2.39:1.[1] Two common videographic aspect ratios are 4:3 (1.33:1),[a] the universal video format of the 20th century, and 16:9 (1.77:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently."
[1] The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' American Cinematographer Manual (Many widescreen films before the 1970 SMPTE revision used 2.35:1).
How about adding the most common film formats?
The play of this video was sluggish. This may be due, in part, to the format. Other players ran the film more smoothly and with the correct aspect ratio, but had problems with crashing 19:57 minutes into the film. The screen would turn green and a multi-colored strip of pixels appeared across the top, about three millimeters high.
Hope this helps.
