Hi NCH After replying to a question regarding changing the speed of a clip/part of a clip, is there any possibility that a SPEED effect could be incorporated into the FX "Motion" options. I can see this being useful where a gradual acceleration or deceleration of a clip could be achieved using keyframes. Currently this can't be done without chopping up the clip into small pieces manually and applying a different speed to each. Nat
I am using the latest version of Videopad professional (v3.81), on a Windows 32 bit machine running Windows 7. The two faults have been present in previous versions too, and are easily replicated. Take any two clips, with movement so that each frame transition can be easily seen, and place them on the timeline (could also accomplish this by placing a single clip on the timeline and splitting it). If this simple sequence if exported, everything is fine. Now, firstly, if a simple fade transition is used between the two clips, everything appears fine on the sequence pane when stepping through frame by frame. However, when exported (mp4, H264), duplicated frames exist at the start, mid-point, and end of the transition. Frames are also missing, so that the exported sequence is the same length as the original sequence. These duplicated/missing frames can be easily seen by adding the exported video file to the project, and stepping through, frame by frame, and comparing to the original sequence. Secondly, if we return to the original dual clip sequence, without a transition, and add a visual effect (e.g. brightness) to the second clip as an effect across the whole clip, without using keyframes, then the exported file is fine. However, if we use keyframes to vary the brightness across the clip, then the exported file has several duplicated/missing frames across the whole clip (seem to occur every fourth frame). Both of these faults cause visible stuttering in the exported file, which renders these effects/transitions unusable. These problems have existed in the software for several months, across several updates/releases. I cannot use the software in its present form, which is a pity, as other than these significant faults, the software is nice to use. Please advise.
