problem incongruence sync between playback/pause
Hi everybody
I’m Italian, sorry for my english.
I’ve a big problem with fc pro: I have the audio track and the video track, recorded from two different devices, imported in my project, then synced in my timeline. All is good when I watch playback. But when I press pause the video is not sync anymore. Worse: at the beginning of the clips. both audio and video are synced, but going on the video go little by little away from the “right point” till the end, where is many seconds out of sync. I repeat, I see all this only when the timeline is paused, but the playback is ok at every point. The export confirm that thing, making me see the video going out of sync graduately. I encountered this problem again and I fixed it enlarging the size of the clip from 100% to 100,01%, so it lose the render, and after rendering all works, but in that case the out of sync was constant. How can I fix something that lose sync graduately??!!
Maybe it can help you to give me an answer:
I use a macbook pro OSX 10.7.4 8 GB RAM, 1 GB videoboard
My software version is fc pro 7.0, never update (I’m a donkey, but I’m afraid that with some updates I will lose my copy of the software, cause I’ve not “exactly” bought it)
The Video clip format is (copied from fc browser): mp4, 1920×1080, 25 fps, compressor H264, data rate 2,1 MB/sec. (Originally it was a sony .MTS HD format, converted into the format above using “Aimersoft Video Converter”
The Audio clip format is: DAT RATE 187,5 K/sec; AUD RATE 48,0 KHz; AUD FORMAT 16 bit-integer.

Ehm…
ok, I fixed it… I re-convert the mp4, again in mp4, using the same settings and the same converter… and now magically works….
no words…
Anyway if someone could explain to me why this gradual de-sync happens I really appreciate…
Thank you

mp4 or H264 are not editing codecs. Convert in Compressor to ProRes 422

I need all the basics of compressor… never learn to use it…
can you indicate to me a good tutorial… or some basic instructions maybe?
for example, did compressor read .mts files (sony Handycam HD)? that was the source format

.MTS files? From an AVCHD camera? You need to use Log and Transfer to convert the footage. I have a tutorial:
