Hi,

I would like to product M2TS file at 1080i/50 to playback on WDTV Live. But it has to confirm to High Profile 4.1 My source videos were recorded at PAL 1080i/50 at 24mbps.

If possible, I would like to retain 50fps in producing. WDTV Live stutters at 1080/50p playback and loses sound as it is apparently High Profile 4.2

I've produced at 25p but the playback is jerky in fast moving scenes.

How can I retain 50fps smooth playback whilst comforming to the High Profile 4.1 requirement?

What is the recommended video/audio setting to satisfy HP 4.1? Can I set average video framerate to 24mbps at CABAC encoding and still conform to HP 4.1? Audio is 256kps. If not, what is the maximum average video framework to choose?

Would be grateful for any advice.

Hi Mergen -

Using the AVC profile in the image below will give you the closest to what you want with PD10. The AVC profile used is High @ 4.0 in PD10 (PD uses 4.1). By default, the audio is 256Kbps

By clicking the + button you can customise the profile if you wish.

Cheers - Tony

Thanks, Tony.

But when I select the AVCHD 1920 x 1080/50i (24mbps) profile and click on the "+" sign for more information, it defaults to 25i frames, not 50i frames. If I change the default video setting from 25i to 50i, it then becomes a custom profile. Can you try it and see if it happens on your system? Is this a bug in PD10 or did my camera actually recorded 50 frames under a 25i container format?

The funny thing is, AVC HP 4.1 specification does not list 50i. It says 1920x1080 25/30i, 1920 x 1080 24p and 1280x720 50/60p. So what category does 1920 x 108 50i fall into? I don't think it comes under HP 4.2

Any owners of WDTV Live have problems playing 1920 x 1080/50i files?

Hi Mergen -

Here's some information about compatible playback formats from WD - http://wdc.custhelp.com/app/answers/detail/a_id/2698/p/208,333/session/L3RpbWUvMTM2NDc4MDk1NC9zaWQvTG15REVBbWw%3D

I use the WD TV HD Media Player and have had no trouble (video or audio) with playback using a variety of formats & profiles - typically AVC H.264 1920x1080/50i (20MBps)

Cheers - Tony
