Let us say both to beginning and end but not the middle where the camera is doing a slow pan.

The MSU_FRC is not working yet as AutoCrop() command not recognised.

Will check.

Yeah, that's what I thought. Very easy:

Code: [Select]
v = MpegAutoIndexSource("HD video by Canon SX50 camera - 50x zoom example 1.mp4")
fps = v.FrameRate()

v1 = v.Trim(50, 75).AssumeFPS(fps/4)
v2 = v.Trim(76, 175)
v3 = v.Trim(176, 200).AssumeFPS(fps/4)

#v = v1.ConvertToYV12().AutoCrop(0, wMultOf=16, hMultOf=16).MSU_FRC(4, "fast") + v2 + v3.ConvertToYV12().AutoCrop(0, wMultOf=16, hMultOf=16).MSU_FRC(4, "fast")
v = Dissolve(v1.ConvertToYV12().AutoCrop(0, wMultOf=16, hMultOf=16).MSU_FRC(4, "fast"), v2, v3.ConvertToYV12().AutoCrop(0, wMultOf=16, hMultOf=16).MSU_FRC(4, "fast"), 10)

return v

You can use either but Dissolve has better transitions.

zoom split

You have to install the plug-in: new version of AutoCrop plugin

Yes, I have now installed the AutoCrop plugin but am stuck with ConvertToYV12.

Says the input image format is not suitable.

Please post the script. Read: Convert.

BTW, can you move all the stuff that is not directly related to time-lapse to a new thread? This is way off topic by now.

reyalp will move it to 'Movie processing with AviSynth'.

The script is same as above but using the alternative syntax and does not return a clip.
QTSource() is used to input the original MOV file which I believe is RGB colour space.
Everything works up until ConvertToYV12().

Will read the link.

P.S.

I have a LOT of timelapses taken this year, my apple tree timelapse has been running since April.

That's too general. How about 'Panning a panorama image and slowing down a video using AviSynth'?

RGB should work acc. to docs. Did you try MpegAutoIndexSource? My clip is YUV like I believe yours is and it worked for me.

That sounds cool. Be sure to post the video.

No, because QTsource loads the file OK.

That looks remarkably similar to mine which was also shot on an SX50:

Frame rate : 23.976 fps
Color space : YUV

All the more reason you should be using MpegAutoIndexSource, which worked for me. What are you waiting for?

You used it on an mp4 file not a mov file.

However, it apparently supports mov so I will try it.

According to the Convert link you gave, the SX50hs' YUV colour space with 4:2:0 subsampling IS YV12.
However, if ConvertToYV12 is omitted FRC complains.
