Weird Speed Issue

[Mike Truly]

Edius is incapable of generating a still in a bitmap type format (such as TGA, etc.) where the brightness/look-of-the-image is IDENTICAL to an adjacent HQ clip when that still is used on the timeline abutting the original HQ clip. This was confirmed by others in a thread long ago and Brandon gave me the only viable solution which is to render a single frame HQ file of the desired still area and then adjust the speed of that still HQ clip to be as long as desired.

This produces an identical still and works well (although it's a bit of a hassle to have to set IN and OUT points, render, adjust speed settings, etc. before being able to place/adjust the still clip on the timeline. It would be far better if GV simply made a function where the user could save an 'HQ-Still' in one easy step and then drag the IN/OUT of the still clip without the need for the speed settings hassle... but I digress).

But my current problem is this. Normally, this one-frame HQ method works flawlessly for me. I render the HQ clip, set the speed to something like .11, set de-interlace to NONE and then adjust this clip on the timeline.

But for some reason, I have just rendered an HQ one-frame clip, and when I go to set the speed, the clips instantly becomes half-res. If I set the speed back to 100%... the clip is full-res again. Anything less than 100% and the clip drops to half-res. It's like the clip is being de-interlaced even though I have set de-interlace to NONE.

Is this a known issue I've missed with 4.61? I should note that this is an older project that has been opened in 4.61.

Any ideas?

Thanks!

Another tidbit on this.

When I take a one-frame HQ clip and I put it on the timeline and set the speed to be 25% (with de-interlace on NONE)... I now have a 4 frame clip on the timeline. This is as desired.

But when I then scroll through and examine that clip... the 1st frame is half-res, the 2nd frame is full-res, the 3rd frame is half-res and the 4th frame is half-res.

One of the fixes of 4.61 had to do with a negative speed... I wonder if the Speed function has been wacked in some way?

Thanks!

Editing HDV 1440 X 1080i and getting grabs from time line to use right next to HQ clip and last frame and still are identical in every way? I have not tryed in SD and its 50i

Are you using sd footage?

[Rusty]

Have you tried making 1 frame 1% speed?

Thanks!

I did that 15 years ago with Matrox Digisuite and Speed Razor, export 1 frame to matrox avi and drag it back to timeline, it would automatically be the duration set by still duration, in my case 4 seconds, I was then able to stretch it to any duration

Thanks for the ideas folks. I should have given a bit more information.

Using the 'render HQ single frame' method is required because using the bitmap render method produces bitmaps with a slight difference (best described as a slight change in brightness) when the still is used directly abutting the original HQ clip. This was confirmed long ago and the 'render HQ single frame' method has worked flawlessly for me in the past.

This particular project is D1 SD res. It is computer animation that is rendered as progressive (no fields).

I have tried many speed settings such as 1%, 25%, 50%, etc. and each is producing the same result. Normally, I always use .11% (Edius refuses to take a .1% for some reason but takes a .11% just fine).

Tommorrow I will do some more testing on other res projects such as 720p to see if it's working there and perhaps is related to loading this older SD project in 4.61.

Thanks!

I have tested a 720p project and in that, I can render a one-frame HQ clip and then adjust the Speed and it does NOT make the clip appear half-res.

But the SD project does have the problem with Speed. Any Speed other than 100% results in a half-res image. The attached images are rendered stills that show what appears as the result of various Speed settings. The first shows the one-frame HQ clip at 100% speed... the image is full res. The second shows the one-frame HQ clip at 1% speed... the image is half res.

This is on a 720x486 SD project. Can someone test and see if they get similar results on a similar project?

Thanks!

[Mike Truly]

ONe other thing to note. If I take the one-frame HQ clip and set the speed to something other than 100%... I get a half-res image. But as I scroll through that speed-adjusted clip, the visual result is NOT constant. It changes as I scroll through that clip.

For example, as I scroll through the beginning of the clip... it is half-res. As I get to about the 25% point of the clip, the image looks as though it is dissolving to something closer to full-res. As I get to about the 50% point, it dissolves back to half-res and stays like that until the end of the clip. This is with only this single clip on the timeline... nothing else influencing anything in any way.

Weird.

Thanks!

can you make available 1 frame of the problem avi so I can apply slomo to it and see for myself

[Mike Truly]

Anton,

Sorry for the delay in getting back to this.

Attached is a one-frame HQ clip. In an SD 720x486 project, when Speed is set to anything other than 100%... I get a half-res image. 100% gives a full-res image.

(I just tested again in another area of the timeline rendering a one-frame HQ clip and settings the Speed... same result).


Thanks!
