NO EX1R AUDIO with new beta from HDLink

[Stephen Armour]

Okay, I'm sure this has an easy answer........right?

We just converted a bunch of clips with HDLink and using the new beta 5.2.2 .

Video's fine but NO AUDIO! It sounds like a bunch of static. We know there is original audio in the EX1R originals, as we can play them back in the cam.

Suggestions? We rolled back to the previous version and same story...NO AUDIO.

HELP!!!

[Jake Segraves]

what were the audio settings used in camera? send a sample file to support and we'll check it out.

[Stephen Armour]

Cameraman's gone already, Jake, so I'll have to get that to you tomorrow. I assume you're referring to sending an original mp4 file, right? It's totally normal when played back direct from the cam

I'll check it out with him for audio settings and a file tomorrow. It'll have to be a short file as our internet is VERY slow.

Yes, confirmed, EX1 audio is coming out byte swapped. Funny thing is we haven't changed anything in this area either. We will explore further.

I have problem too with this build and with the sound. This is when I convert my 1280x720 (pal) filmscan-2 file to 720x576 (pal) widescreen, I get just pink noise.

Another strange thing is that when I use Premiere CS3 I can do a perfect resize within Premiere timeline export from 1280x720p (pal) to 720x576 widescreen (pal), but inside CS5 I get black sidebar?

Strange?

Regards
Mikael

We'll hold further CF conversions from EX1R source files until you can squash this serious bug.

Hopefully it's something simple and you'll have a new beta out for us ASAP.

We've got lots of work stacked up and this will now require a pile of recaptures. Doing the audio separately and re-linking it all is a pain, but an easy workaround, so it's no showstopper.

The hiss has been fixed for XDCAM EX sources, and will be available in the next build.

@ Mikael

The black bars come about because since CS4, Adobe has treated the PAL SD anamorphic image as being equivalent to 1050x576 square pixels, rather than the previous 1024x576. It seems odd but is in fact 'correct', in as much as a circle on a TV should appear perfectly circular. The bars should be outside TV safe on a televison, but are obvious on an overscanned screen (such as the computer).

A 102.5% horizontal scale will get rid of them, though circles will go a little squat (as they did in CS3 and before, which shows how subtle it is!)

For a thorough explanation:

Instead of scaling up footage i use the Crop feature in the Export Settings dialog and crop ~13 pixels at the Top and at the Bottom. Use the Output tab to verify that the black bars are gone. Go back to the Source tab and re-adjust if needed.

By cropping one does not need to upscale the footage and thus loose some quality, and the circles are perfect. :)

I wish the new PAR's will find its way into HDLink as well since the geometry of downscaled HD footage is lost when using HDLink to downscale. :)

Same problem here with the hiss. I simply exported the video from preimiere CS5 as a Cineform AVI file and then put the outputed file back into a premiere CS5 timeline. White noise on the audio. It seems to be a problem with the decoder, as previously creaded Cineform files now hiss when played back in Premiere CS5.

[David Newman]

Scott, that is completely unrelated, so please contact support as you may have discover a different issue, as no one else has reported this. The hiss in the audio discussed in this thread is for EX1/3 files converted in HDLink, it has nothing to do with Premeire. The HDLink issue has been fixed in the upcoming v5.2.2
