ok, das mit den Lizenzschlüsseln habe ich nicht bedacht. Es wurde nach den Seriennummern gefragt...das hab ich verwechselt.

Nun wieder zur Sache:

1. VDL2015 lief zufriedenstellend

2. Nach Update ruckelt die Vorschau und ist unbrauchbar

3. Das tritt immer auf und hat nichts mit alten oder neuen Versionen zu tun. EIn neues leeres Projekt, ein Video rein, Vorschau und ->ruckelt.

4. Das alles spielt sich auf identischer HW und BS ab. Daher nehme ich an das dies als Grund ausfällt. Bin aber nicht sicher, daher anbei ein HW-Report.

5. Evtl. interessant: Ein Wechsel zwischen MainConcept und Standard bringt in dieser Hinsicht keinen Unterschied.

Ich hatte gehofft, dass jemand so etwas schon mal hatte und das Problem gelöst hat.

Ok, hier der Report:

ok, das mit den Lizenzschlüsseln habe ich nicht bedacht. Es wurde nach den Seriennummern gefragt...das hab ich verwechselt.

Nein, es wurde nach der Versionsnummer gefragt!

Versionsnummer findest Du hier:

Gruß

Also nur zur Kalrstellung: Außer dem Update auf VDL 2016 Premium habe ich keine Änderung am Rechner gemacht, keine Cleaningtools oder ähnliches.

Bis unmittelbar vor dem Update lief VDL2015 so wie immer, Vorschau von einem Video lief recht flüssig, hakelig wurde es nur bei vielen Spuren oder mehreren Effekten. So wie es zu erwarten war.

Nach dem Update sind beide Programme -was die Vorschau betrifft- unbrauchbar.

Auf dem Notebook sind schon ein paar Programme installiert, aber der effekt ist mit Sicherheit auf den Update zurückzuführen. Auch mehrfacher Neustart des Rechners brachte keinen Unterschied.

NB: Ich bin ein Anwender. Viele Details meines Rechners kenne ich nicht oder nicht inder evtl. erforderlichen Tiefe. SInd mir auch egal. Ich will ja gerne versuchen solche Infos zu besorgen, daher der hier gepostete Report.

Egal, ich würde mich freuen wenn es mal etwas Sachdienliches gäbe.

Nachtrag: Evtl. ist es interessant, dass die Anzeige eines Videos mit der "Pfeil-Rechts" Taste recht flüssig läuft. Wenn die Vorschau genauso liefe wäre das ok.

Für mich als Laien bedeutet dies das das Rendern nicht das Problem darstellt. Oder liege ich falsch?

ok, der Uodate auf die aktuelle Version von dotnet brachte: Genau nichts.
