Vorn has a point,

I have a Samsung TV and it plays pretty much everything.  Oddly enough though the matching Samsung Blu-ray player, which also plays from USB sticks, is more fussy about file formats.  So some things play on the TV but don't play through the blur-ray machine.

My friend also has a Sony Bravia and as Vorn says it's much more fussy about file formats.  I was very surprised to discover that his Sony Bravia does not play mkv files, for example.

So it would seem to depend on the TV itself and if you can find out the exact type of TV that is being used, you can always check the manual online for more information.

I would suggest that an MP4 file will be the safest bet though, using H264 encoding.  You might need some guidelines regarding bit rate.  If you want high quality, you're probably looking at anywhere from 5000 - 20000 kbps.

Subject: Re: [AE] Frame rate for digital file

I'm going to sound a bit pedantic, but there is no PAL or NTSC any more.  They were analogue transmission standards and they're history.  Once you're in the digital world there's just resolution, frame rate, and either progressive or interlaced.  Even interlacing seems to be on the way out.

If you have a TV that is new enough to play a digital file from a USB stick or other device then it will be able to play any common frame rate and resolution.  

Digital files already come in a range of resolutions, most commonly 1280 x 720 and 1920 x 1080.  But there are many others - especially if you start looking at downloaded or ripped movies that were originally letterboxed.  And frame rates - you'll find 23.976, 24, 25, 29.97, 30 and more.  A modern TV can handle all of these different resolutions and frame rates.

I don't think a Sony or a Samsung TV will have any problems with a .mov, but you might find some obscure TVs that prefer a mp4 rather than a .mov.  But basically - if you have a TV that can play files off a stick then it will be able to handle 1920 x 1080 @ 25 fps.

If you have a master file you're compressing for delivery then it isn't too hard to make a range of different files to avoid compatibility problems.  It's not hard to deliver an MP4 and a MOV, for example.  And if you're compressing on a Mac then Apple's built-in defaults for apple TV and iTunes devices are worth trying too.

Esteemed AE professionals,

I'm rendering an HD 1920x1080 25fps AE sequence. The client intends to play the digital file from a dongle directly into a TV. 
Do I need to ensure I have both NTSC and PAL frame rate versions if they are taking it to the US (I'm UK based) or will the 25fps suffice?

I'm also rendering with QT using H264, if anyone knows of a better format to render to for this particular purpose I would appreciate the feedback.

Many thanks for any help given folks,

Marc
