[VP16_248] Stabilize crashing on frame rate mismatch

AVsupport wrote on 8/26/2018, 7:43 PM

With excitement I tried out the new 'Video Stabilization' with XAVC-S 50p source clips on a 25p timeline. This lead to repeated crashes on analzye or attempted playback. Only keeping project framerate and clips identical allowed me to successfully deploy Stabilize.

Attempting to further stabilize somewhat 'floatey' gimbal footage (z-axis walking motion) didn't really offer many improvements in my situation sadly. So far my first impressions of the plugin are slightly underwhelming in this particular scenario

Is there any ability to combine motion tracking and video stabilisation to stabalise an object/person in the video rather than stabalising the camera?

@AVsupport

What framerates are you working with?

AVsupport wrote on 8/27/2018, 1:25 AM

as I said OP, 50fps (double PAL) on a 25fps (PAL) timeline. not working. everything in 50 is fine.

Peter_P wrote on 8/27/2018, 1:31 AM

Sorry I missed that. If you are using same frame rates, what preview fps do you get.

AVsupport wrote on 8/27/2018, 1:34 AM

all of em. fast system. that's not the issue I believe. As it's also crashing during Analyze.

Peter_P wrote on 8/27/2018, 1:40 AM

It is not crashing on my system (i7-8700k) with UHDp30 footage- Not in Analyze nor in preview. You did use it as a media FX, did you ?

AVsupport wrote on 8/27/2018, 1:48 AM

@Peter_P try to use 60p footage on a 30p timeline if you can, for a valid comparison; and Yes you have to use media FX, as there's no other way..

What resolution are you using?

AVsupport wrote on 8/27/2018, 2:16 AM

1920x1080 XAVC-S

I'm currently only using UHDp30 XAVC-S footage, but found some older XAVC-S with FHDp50. This 50p footage in a FHDp25 timeline with the default FX setting and 'Avoild black borders analyzes fine and preview is 25fps in internal window. So the preview performance issue comes up with UHD footage and not with FHD on my system.

@Former user

Yes sure you can. This video was taken with a long focal length and free hand by me. I just edited a 1080p50 clip which is stabilized in Vp16 with the new media FX and uses the new motion tracking feature.

Former user wrote on 8/27/2018, 5:29 AM

Did you mean to share the clip or were you just confirming it can be done?

thanks either way.

Peter_P wrote on 8/27/2018, 5:52 AM

I tried to upload it here directly, but it did not work.

AVsupport wrote on 8/27/2018, 6:08 AM

It was the VP16 crashing that was what concerned me the most. When it was 'working', the 'performance' of the plugin was fine (I didn't have playback performance issues). Apart from the Quality of the result which if it was to be discussed, but that's another matter entirely

@AVsupport

Not on my system. As I wrote, I also had 1920x1080 (FHD) 50p XAVC-S footage on a 25fps timeline and Vp16 did not crash.

AVsupport wrote on 8/27/2018, 7:03 AM

interesting. how long were your clips? how many have you tried?

Peter_P wrote on 8/27/2018, 8:33 AM

Since you have to stabilize one clip after the othe I just used one of about 10s in length. If you tell me the number you used, I can try this again.

Thankyou for your example. This is what I mean. In this video, camera stabalise & object stabalise.

Can vegas do object stabalise when associated with motion tracker?

thankyou

Peter_P wrote on 8/27/2018, 9:42 AM

I did not try, but would assume not with the Vp16 internal stabilizer. Because the stabilizer is to be used as a Media FX and thereby can not be part of a FX-chain, where you can change the order of the FXes. But this should be possible with the Mercalli V4 plugin, which is to be used as an event FX.

Good to hear!

Blastrio wrote on 8/27/2018, 4:45 PM

In my case, it crashes even when the project frame rate matches the clip's.

AVsupport wrote on 8/27/2018, 5:29 PM

@Peter_P I noticed you mentioning in another post you had So4... disabled. Is that the case for your above stabilization tests?

@Blastrio what source clips are you using?

Does Mercalli V4 work with Vegas 16?
