Avid Xpress Pro: Strange Quicktime Export problem ...
Frage von Maik: November 2007
I will either slowly crazy, or my Avid spins. I have a rather strange problem with Quicktime reference export files from Avid.
First: After export a sequence as QTR I have seen when looking in QuickTime s.mehreren strange places Farbspratzer. There are large square area with small colored squares, sometimes but synonymous chessboard-like gray squares (between 4-6) on the Picture. The problem is, they occur only when playing on, so I can eg no screenshot ... if I have the appropriate location by hand Frame by frame in search is nothing to find.
Second: This Spratzer I have not in the original material. The original is as single track on the timeline, no effects, etc. A re-export as QTR brings similar effects s.anderen bodies. With each playing but s.gleichen place! New Export, Spratzer s.anderer body, but always the same, uswusf.
Third: Further processing of the QTR in Sorenson Squeeze, since the Spratzer in the MPG with included and are synonymous in each frame. Screenshot synonymous not possible here, because Media Player, for example, the frame can not spend.
Software: Avid Xpress Pro 4.5 Sorenson Squeeze 4.2 Quicktime 7.2
What is going on? Is there somewhere to help me? incomprehensible,
Antwort von WoWu:
... how is the original format and then you expect to MPEG? Sounds like an aborted quantization. "n" is perhaps not deep enough or set the Encodieralgorithmus on the "View", in order to encode the "fast" is. The "real-time coding" means in relation to the image quality is always the worst choice.
Antwort von WoWu:
... did you have a picture somewhere to view uploaded?
Antwort von emu:
Xpress Pro 4.5 and QuickTime 7.2?
QT 7.2 is only since Xpress Pro 5.7.5 officially supported. Did you have problems always or sometimes ran the neatly in the Kombi?
Antwort von Maik:
So, new day, new luck, I thought and I've just tried again. What can I say? I have just an error-free export target. The MPS expects straight, but I assume that the synonymous what will. The only difference from yesterday is: the calculator is still cold and I've disconnected the external disk. I had yesterday, but synonymous sometimes only the internal disk probiert, functioned not synonymous. The thing is bewitched, maybe a temperature problem of the computer? Or external hard drive has a quirk.
@ Wolfgang: Screenshots of the phenomenon were not possible, Original was HDV -> DV downconvert to 16:9 (in the Camera), I had The doll has theories regarding MPG compression errors that insidiously and enforced only in the third format change occurs, the material on the timeline in any case was always clean and showed no disturbances.
@ Emu: I had Quicktime 6.5 first, which I hate yesterday in an emergency upgraded to 7.2 The error was in both versions.
... the calculated MPG is now ready ... and has no disturbance. So probably some hardware problem, temperature-related. I tasted 5 hours yesterday. I think not.
