Audio Problem with HDV footage
Hi, sorry if this has been discussed all ready but I have found no answers.
I have exported a clip from FCP using current settings. Footage is HDV 1080i50. Once rendered the clip plays fine in QT and also in the project window of AE, but once i put it into a comp, the audio seems to dissapear, this is driving me crazy! As I exported another clip from the same timeline and it works.. Im stumed. When I look at the properties of both clips they are identicle, but one plays and one does not.
Video track HDV 1080i50
Sound track 1 : Integer (Little Indian)
Sound track 2 : Integer (Little Indian)So why does one not play????? Ive re rendered it and still nothing….. STUMPED.
Any help would be great thankyou.

Have you inadvertently turned off the audio in the comp. Is the button on the left under the speaker icon selected? Also check the waveform to see if it’s there or if the gain’s been reduced.

Hi John,
The audio is fine on other clips. When I click on the this clip in the project window I can see the waveform on the thumbnail of the clip, and it previews with audio. But once its in a comp and I click down to the waveform it just displays two flat lines. Have been using hdv footage for a while and have never come across this.
Any other ideas?

When you twirl down the audio arrow is the audio level at 0.00dB? If not, change the level to that and see if the audio & waveform return. If that’s not it, I’m baffled. Maybe try posting this in the AfterFX forum.

Yeah its at 0.00dB. Yeah its very odd. It has wave form in AE it the project window then just dissapears. I posted this in AE forum but CCow moved it here.. Thanks for your efforts! 🙂

Might be worth an email to Adobe support. Please post back if you figure this out.

Hi John, I will email Adobe when I get a chance, have just found a workaround for the time being. I am still stummped at what is happening. This is my work around.
1. I rendered from FCP with my current settings in my case HDV1080i50 (adjust to whatever setting you are using)
– Did not have audio on time line when opened in AE
2. Open clip in QT and then rendered using HDV1080i50(the same as i did out of FCP.) (adjust to whatever setting you are using)
– Audio works fine in AE
No idea what is causing this, hope this workaround helps some people before the real solution is found.
Ive posted it on the other thread as well. Very interesting.
Thanks for your input. I might host the clips somewere and see if someone can figure it out but it must be something about how FCP is encoding the audio…. I really dont know!
Thanks for your input John.
