Hi everyone,
I hope the topic heading makes sense, I'm VERY new to video encoding!
I have a number of video files that I am trying to play on my Panasonic Smart TV. Most of the videos play just fine, but I have a few that do some really weird stuff. When I play these problem files the audio appears to be fine, but the picture appears to jump randomly forward very quickly, just showing individual frames for a few seconds before jumping to another still frame.
I've done a lot of reading, which has led me to download mediainfo and take a closer look at the encoding methods used in the videos. All the videos that WORK have the following details:
Video
ID : 1
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Main@L3.1
Format settings, CABAC : Yes
Format settings, ReFrames : 4 frames
Codec ID : avc1
Codec ID/Info : Advanced Video Coding
Duration : 11mn 10s
Bit rate : 1 360 Kbps
Width : 1 280 pixels
Height : 718 pixels
Display aspect ratio : 16:9
Frame rate mode : Variable
Frame rate : 29.970 fps
Minimum frame rate : 29.412 fps
Maximum frame rate : 30.303 fps
All the videos that DO NOT WORK have these details:
Video
ID : 1
Format : AVC
Format/Info : Advanced Video Codec
Format profile : High@L5.0
Format settings, CABAC : Yes
Format settings, ReFrames : 11 frames
Codec ID : avc1
Codec ID/Info : Advanced Video Coding
Duration : 11mn 27s
Bit rate : 917 Kbps
Width : 1 280 pixels
Height : 720 pixels
Display aspect ratio : 16:9
Frame rate mode : Variable
Frame rate : 23.976 fps
Minimum frame rate : 23.810 fps
Maximum frame rate : 24.390 fps
The main differences I can see are the format profile and the REFrames, although I don't really understand what those mean! Could anyone suggest if these differences are likely to be the problem? If so, could anyone also suggest the simplest way to re encode the videos so they have the same encoding parameters as the working videos?
I have tried re encoding using handbrake, setting it for Apple TV 2 output and this resulted in the videos crashing altogether at around the half way point. I'm at a loss as to what I should try next for any advice at all would be greatly appreciated.
Thank you!
