load video with sound?

[CharlieC]

hi all-

when i'm animating i always want to reference my previously-made animatic within my tvp animation project. i load the animatic into tvp as a guide layer so i know how long the sequence is and where stuff is happening in time. however- usually there is sound to consider too, but since (i think) tvp can't use the sound in a video, i must create a .wav file from the animatic, then load both the animatic and the new .wav into the tvp project separately and then sync them both up again. so in effect i work hard on visual and audio syncs to create the animatic, then when i want to create the animation matching the animatic i have to un-sync the animatic's picture and audio to bring both into tvp, only to try and sync them up again in tvp, and hope i haven't created new sync errors.

my above method reminds me of airline passengers carefully packing at home, only to be required by airport security to unpack and undress, then hurriedly dress and pack again to catch their plane... (i suspect some sadistic conspiracy here...)

surely there's a better way than i've found, yes? referencing picture with sound must be a very common need for all the tvp users...

thanks!

Well, of course TVPaint can load a video and the sound at the same time

You just have to check "import sound" in the import footage panel.

(sacreblue!)
so glad i asked.

well-
i've checked the 'import audio' and i've tested several video formats and i still don't get audio when loading video that has audio; no sound wave indicated in the 'master' sound timeline area, no audio during playback preview with audio button lit.
i tried .mov's uncompressed and h264, then .avi, .wmv.
video and tvp prefs set to audio rate of 41.000.
'playback proj sound in clip' checked.

i'll keep checking around; any other ideas appreciated.

thanks,

.avi .mov are just containers, while h264 refers to the images compression ...

how is compressed the audio datas in those files ?

hi Fabrice-

how is compressed the audio datas in those files ?

.mov sound settings are usually AAC, 44.100 khz or 48.000khz, mono, bit rate 64 kbps; is that the compression you mean?

anyway i'm not done experimenting but i notice that i can bring video in with its audio when i load into the project tab, and the clip tab, but NOT the layer tab into an existing clip; is that the problem? so i copied/pasted all my layers into the new tvp clip with video and sound; that seems to be a work-around for now. but loading video as a layer into an existing clip is supposed to load sound as well if checked?

odd- seems that when NOT preloaded the visual sync pops don't stay on the same frame #, they slip around a few frames either side as i shuttle thru the frames. but when preloaded they're locked into a frame as i'd expect.


thanks again,

mmmmm... mono may be the problem...
Try with the same parameters but stereo instead of mono.

When not preloaded, we are entirely dependent on the codec. We ask it to return frame number N, it does what he can to fullfill that request, but because of the compression, it is not always possible, or not fast enough.
For exemple, an mp4 with a keyframe every second, if you ask for the frame just before the keyframe, the codec has to rewind to the keyframe before that one, uncompress all the frames between those two keyframes, to just return the last one.
